ISO 55000 – International Asset Lifecycle Management Standards

ISO 55000 is a set of international standards focusing on Asset Management, and originating from the British Standards Institute’s ‘Publicly Available Specification 55’ (PAS 55). The ISO Standard which was released on January 15, 2014, has now largely replaced PAS 55 as the default global standard for best practice in Asset Management.

The Standard itself is comprised of three components:

ISO 55000 – Provides an overview, key concepts and terminology in asset management.
ISO 55001 – Defines the requirements of an asset management system
ISO 55002 – Details how such an asset management system can be implemented

The ISO 55000 set of standards can be applied to all types of assets and by all types and sizes of organizations.

Why is this standard important?

Unified Process

The ISO 55000 framework guides organizations into developing a unified Asset Management Framework that aligns processes, resources and functional business units. A unified approach to Asset Management drives productivity and business performance.

Compliance

The ISO 55000 standard provides a consensus on what Asset Management is and how it can generate benefits for all organizations, which in turn ensures that organizations are both effective and reliable. Subsequently, businesses are increasingly seeking suppliers and partners that comply with the ISO 55000 standard.

Continuous Improvement

Regardless of Industry, Business Size or Asset Structure, Continuous Improvement is a critical mechanism in ensuring optimized productivity and controlling costs. There is always room for improvement, particularly within asset intensive organizations, and an effective Asset Management system designed around the ISO 55000 framework is essential in driving this process.

Integration with other Industry standards

ISO 55000 integrates with other management standards such as: ISO 9001 for quality management, ISO 14001 for environmental management, OHSAS 18000 for occupational health and safety, and ISO 31000 for risk management. This enables company-wide improvements and inter-organizational synergy.

How barcode scanners can give your business more efficiency & accuracy.

When it comes to streamlining business and making processes leaner, barcode scanners are vital tools. Because they are able to automate what has traditionally been a time-intensive process, barcode scanners save significant amounts of time and money for companies. How exactly do they do this? Why are barcode scanners excellent efficiency-boosting tools? Why are they a smart choice over manual inventory processes? To help answer these questions, here’s a look at specific ways that barcode scanners are good for business:

Easy and Convenient Setup: Implementing barcode scanners into an inventory system is not difficult. In fact, barcode scanners are specially designed to be up and running within as little as one day of business. Most barcode devices operate with a simple driver and little programming, and many also come with wireless capabilities so that you can take them anywhere to scan items. What’s more, because they are simple to use, training employees in how to implement them is fast and easy. Then, as soon as they’re installed, barcode scanners make it possible to experience all the business benefits that come from automated inventory control.


A Way to Prevent Human Errors: When employees have to manually enter information for each product in your inventory, they are going to make mistakes — and those mistakes cost money. Barcode scanners eliminate this inconvenience by turning long and complicated data input into an automated, streamlined process done by machine.


Less Paper Waste: Using barcode scanners lowers the amount of paper your company needs to track products, which is good both for the environment and for your bottom line. What’s more, moving from paper records to digital ones improves organization.


Faster Inventory Management: Barcode scanners automate the data inputting process so that companies can record huge amounts of information in shorter periods of time. Instead of manually keying in each product’s long serial number, employees get to instantaneously scan in the information and move on. Over the course of one business day or week, a company can save a huge amount of time and energy through this simplified process.


Faster Business Transactions: Barcode scanners improve operations on the client side, too, by making checkouts fast and efficient through simple scanning. Rather than having to manually input each purchased item, cashiers can scan and ring up products in order to serve customers faster and better.
Easier Record Changes: Adjusting prices or running sales is much easier with a barcode system than a manual one. Suddenly, changing prices on your product line is fast and easy — not to mention more accurate.


Faster Inventory Cycle Counts: Forget manually entering each product’s information. With barcode scanners, employees can easily scan relevant information for inventory cycle counts and provide faster, real-time control over inventory systems.


Real-Time Updates to Data: One of the biggest beauties of barcode scanners is that they operate in real time. Rather than looking at inventory logs and expecting some sort of delay in accuracy, companies can get immediate updates to know, at any given moment, what is available and where.
Accurate Historical Inventory Data: The barcode system automatically gives you rich historical data about your inventory, which can then be used to inform your business decisions. You can know which items are popular, which items are often bought together, which items aren’t selling, etc. This information is easily available through automatic records that are created through the barcode system. More accurate data gives you a way to lower your purchasing costs and freight costs by using better economies of scale.


Better Overall Warehouse Management: The bottom line is that barcodes and barcode scanners give a company a way to improve its overall operations. It’s possible to use handheld computers to monitor inventory, it’s easier to predict how much product will be needed to meet customer demand and it’s financially efficient to use the warehouse space you need instead of over-purchasing for products that don’t sell.

Five Facts You May Not Know About ISO 55001

1) ISO 55001:2014 – Asset management – Management systems – Requirementsis the first management system that was developed from the high-level framework defined in ISO/IEC Directives, Part 1, Consolidated ISO Supplement – Procedures Specific to ISO. This “Annex SL”, as it is more commonly referred to, is the former ISO Guide 83, High level structure and identical text for management system standards and common core management system terms and definitions. This annex contains the framework for all management systems going forward and contains 10 common elements (Scope, Normative References, Terms and Definitions, Context of the Organization, Leadership, Planning, Support, Operations, Performance Evaluation, Improvement) that are assembled in a Deming “Plan-Do-Check-Act” continuous improvement process is currently being developed using this framework for quality management systems and will be released next year. 

2) ISO 55001 emphasizes identifying and controlling risk to internal and external stakeholders of the defined asset portfolio, while looking for opportunities for continuous improvement throughout the life cycle. Documenting risks and opportunities are common themes throughout the standard and an organization will find it difficult, if not impossible, to comply with the requirements without following the principles and guidelines found in ISO 31000:2009, Risk Management.

3) The Strategic Asset Management Plan (SAMP) is derived from the Asset Management Policy and specifies the asset management objectives. In development of the SAMP, some level of stakeholder mapping is required in order to define the expectations of both internal and external stakeholders and communicate those expectations through the objectives. This ensures that the plans created for the defined asset portfolio take into account the risk to all stakeholders and specify how that risk will be managed and controlled. Line of sight is a significant theme in the standard. A corporation must be able to follow the golden thread from life cycle activities of their asset portfolio contained within the asset management plans all the way back to their business strategy to show documentation and control of risks and opportunities.

4) The asset management plan is an output of the asset management system and takes into account the technical requirements of the asset portfolio that is within scope of the system. The asset management plan is developed to ensure the asset management objectives are achieved throughout the life cycle. An organization should start small on its asset management plan. When planning how to achieve its asset management  objectives, the organization needs to determine and document:

  • the  method  and  criteria for decision making and  prioritizing of the activities  and  resources to achieve its asset management plans and asset management objectives
  • the processes and methods to be employed in managing its assets over their life cycles
  • what will be done
  • what resources will be required
  • who will be responsible
  • when it will be completed
  • how the results will be evaluated
  • the appropriate time horizons for the asset management  plans
  • the financial and non-financial implications of the asset management plans
  • the review period for the asset management plans
  • actions to address risks and opportunities associated with managing the assets, taking into account how these risks and opportunities can change with time, by establishing processes for:

- identification of risks and opportunities
- assessment of risks and opportunities
- determining the significance of assets in achieving asset management objectives
- implementation of the appropriate treatment, and monitoring, of risks and opportunities.

It is top level management’s responsibility to ensure the organization provides competent resources required for meeting the asset management objectives and for implementing the activities specified in the asset management plans.

5) This management system standard also differs from previous system standards in its focus on collaboration. Top management is required to demonstrate leadership and commitment with respect to the asset management system by promoting cross-functional collaboration within the organization. In his  September 2014 keynote address at the 2014 IADC Drilling HSE Europe Conference in Amsterdam, Transocean President and CEO Steven Newman urged the offshore drilling industry to embrace collaboration in order to go from good to great. BS 11000-1:2010, Collaborative business relationships - A framework specification, considered the standard for collaboration, is currently being adopted by ISO and will be published as ISO 11000:2015 next year.

Five Things to Know Before Choosing an Embedded Data Acquisition Device (From BarcodesInc)

Successful data acquisition for barcode reading or part inspection depends on the ability of the data acquisition device, such as abarcode reader or machine vision camera, to function at peak performance within the restrictions of the application. In applications where barcode reading or machine vision inspection processes are embedded inside of equipment, limited integration space puts a unique set of restrictions on how a device can be installed, not to mention demands on the size and capabilities of the device itself. Before installation, it is important to choose a device with optimal specifications to ensure inspections can be done accurately and consistently throughout the life of the machine. This post outlines the five things an engineer should know before choosing a data acquisition device for embedding into equipment, including:

Barcode Type and Orientation
Inspection Requirements
Application Speed
Integration Space
Data Communication Needs

Automation starts with data. The faster and more accurately data is communicated to a machine, the faster and more accurately the machine can perform its automated functions. In stand-alone machines, data acquisition is often achieved by integrating compact automated devices like barcode readers and machine vision cameras, offering companies the tireless efficiency and precision of machine-based data collection. Unlike human operators who function at an error rate of around 1 out of every 300 data string entries, automated devices acquire data with an error rate of less than 1 in 3,000,000. This level of accuracy greatly favors barcode reading and inspection for tasks ranging from logging product and component information, enabling traceability in production, ensuring data accuracy, and communicating with equipment to trigger additional automated processes such as routing, rejecting, and batching.

However, as with human operators, if a device cannot meet the demands for speed, accuracy, and reliability within an application, the true benefits of automated data acquisition are lost. A device must the right fit for each application in order to provide value to the application. In the case of fully-integrated machines, finding a “right-fit” device to embed inside equipment is often determined by fixed space restrictions and inspection distances or orientations. In addition, the usefulness of equipment that performs automated data acquisition depends on the flexibility and longevity of the automation device inside, so great care should be taken to choose the right device for every embedded application from the start.

To ensure the long-term performance of equipment integrated with automated data acquisition systems, engineers should first fully understand the requirements of the equipment and the application. Five critical things to know before choosing an embedded barcode reader or machine vision camera for an application are: barcode type and orientation, inspection parameters, application speed, integration space, and data communication needs.

1. Barcode Type and Orientation

Barcode Type

Knowing the barcode type is key to narrowing down the list of possibilities when it comes to choosing an embedded barcode reader. Barcode readers may be either laser-based or camera based. Laser-based barcode readers – often referred to as laser scanners – shine a laser spot over the dark and light elements of the barcode, measuring the reflected light from each element as it returns to the scanner, and use the scanner’s photo detector to transform a wave pattern light signal into a code string. Camera-based barcode readers and machine vision devices – often referred to as imagers – use rows of CCD or CMOS sensors in a two-dimensional array (the imager’s built-in camera) to generate an image of a symbol that is decoded using image processing.

Linear (1D) barcode like UPC or stacked symbols like PDF417 can be decoded by both laser scanners and barcode imagers. 2D symbols like QR Code and Data Matrix can only be decoded by 2D imagers. This makes the choice of embedded barcode reader clear for applications requiring 2D code reading.

However, an engineer has some flexibility when it comes to choosing an embedded reader for a 1D barcode. Benefits of laser scanners for reading 1D codes include reliable performance at a lower price point, faster decode rates (up to 1,000 real-time decodes per second), longer-distance reading with greater depth of field, and less complex setup due to the scanner’s simpler hardware. Engineers should also consider device flexibility and scalability when integrating barcode readers or machine vision cameras into machines that are meant to accommodate applications for the long term. Camera-based imagers are capable of reading all code types. As application needs change, more and more operators are turning to smaller, denser 2D code types to encode more data into smaller spaces. A 2D barcode imager or a machine vision camera capable of reading both 1D and 2D codes, therefore, gives operators the flexibility to migrate to 2D code types if needed in the future. Imagers are also more suitable for reading badly-damaged codes in applications where code quality cannot be predicted, using high-performance image processing algorithms to repair symbol images.

Barcode Orientation

Space restrictions or specific design requirements for integrated equipment may dictate that barcodes be fed into a machine at a particular orientation. How a barcode reader or machine vision camera is oriented in relation to the barcode and the direction the barcode is traveling are important considerations when selecting such a device for an application. When choosing a laser scanner, the scanner must always be oriented such that the laser scan line is perpendicular to the bars of the barcode. Additionally, barcodes in motion can be in either “picket fence” (code horizontal, lines vertical) or “ladder” (code vertical, lines horizontal) orientation. Picket fence orientation is generally recommended over ladder orientation because the scanner has more time to scan the entire barcode as it passes through the scan width area.

Unlike 1D laser scanners, imagers can read barcodes in multiple orientations, capturing 2D images to acquire symbol data. For this reason, a 2D barcode imager or machine vision camera is capable of reading any code regardless of orientation. In applications where code orientation in relation to the reader cannot be predicted, an imager may be the preferable choice. Imagers are also beneficial for embedding in machines that require specific mounting positions or angles within a defined integration space that do not always allow scan lines to be perpendicular to the barcodes entering the machine.

Alternately, laser scanners can be equipped with different brackets to accomplish optimal orientation or to negotiate corners and other geometric challenges. For example, right-angle brackets allow the mounting of embedded scanners at 90 degrees relative to the scan beam. Incorporating right-angle mirrors also allows readers to be mounted at angles that do not directly face barcodes, using a mirror to aim the beam from a scanner to a code or reflect barcode images back to the reader.

2. Inspection Requirements

Applications requiring automated data acquisition beyond simple barcode reading (such as barcode quality verification; code, label, or part presence and orientation; product defect detection; color inspection; and other visual inspection processes), require the use of machine vision cameras and software. Machine vision cameras, like 2D barcode imagers, are data acquisition devices that function by taking images of parts or codes to be inspected.

These images are processed by the camera to search for pixel level variations, using software to compare the acquired data from the image to an expected result. This comparison results in images that meet the expected criteria (parts that pass inspection) and images that do not (parts that fail inspections).

The key to acquiring accurate and reliable data for machine vision inspection, as with barcode imaging, is to obtain a complete, high-contrast, and high-resolution image for the camera to process. Application requirements can greatly affect the ability of machine vision cameras to obtain high-quality images. Certain environments may require cameras with a greater ability to meet these criteria. In embedded applications where reducing the mechanical footprint of device components is important, choosing a fully-integrated machine vision system (such as a smart camera engineered with built-in lighting, camera, autofocus, and processor) allows design engineers to ensure that high-quality images are captured without the need to plan for and install excess equipment. Using compact, single-device systems of this type also means that less hardware needs to be programmed and configured in case of future application changes. In the case of machine vision smart cameras, many adjustments can be made from the system’s software after integration from outside of the machine where the camera is embedded.

Again, when embedding a device for automated barcode reading or inspection, it is important to keep in mind the scalability of an embedded device to meet potentially changing criteria during the life of an application. Since machine vision cameras are capable of both barcode imaging and part inspection, it may be appropriate to integrate machine vision devices for barcode reading applications in cases where project scope may expand to combine barcode reading with additional inspection criteria such as barcode presence/absence or placement checks. In addition, it is important to choose a machine vision camera that has the flexibility to meet inspection parameters from basic to advanced. Many smart cameras use software platforms that can be upgraded via camera firmware updates, without the need for physical adjustment. This allows machines to meet a range of inspection parameters, from simple to aggressive, if project needs change in the future. Choosing to integrate a more flexible device of this type greatly enhances the utility of a machine for meeting changing application criteria in the long term.

3. Application Speed

Time is of the essence in automated applications, and time savings is one of the main reasons for implementing an automated machine. Automation helps companies do more with less to increase operational output at a lower cost. Depending on how fast a machine is expected to run, and how fast a device is expected to acquire data for automated processes, certain factors may make one device better-suited for an embedded application than another.

Part of this has to do with differences between laser scanners and image-based barcode and machine vision cameras. Laser scanners can be faster at decoding 1D barcodes than imagers – as fast as 1,000 real-time decodes per second, as noted earlier. This is because the laser scanner is interpreting fewer elements when obtaining an encoded data string from a barcode; it is simply looking at a wave pattern caused by a reflection of light. Camera-based imagers, on the other hand, must capture and process complete 2D images, including barcodes, part features, and any elements surrounding the actual area of interest, and extract data based on thousands of varying pixel elements within the image. This means that imagers can be more precise, but may also have longer decode times depending on the device and application. Recent advancements in processing technology have enabled faster processing times, and choosing a high-speed imager for high-speed applications is critical.

The second consideration when choosing a device to optimize speed performance in embedded applications is data communication rate. How fast does the reader need to communicate decoded data or data-dense images to the outside world? While the data content of a barcode is minimal and easy to transmit over a slower connection such as RS-232, some imaging and inspection applications require higher bandwidth than a serial connection can offer. One common data-intensive task is the recording of inspection images, which can be saved for the diagnostic improvement of operations, proof of barcode legibility, or proof of inspection. Devices with high-speed USB or Ethernet interfaces can easily transmit these images for storage over a high-speed connection without impacting overall application speeds. When using Ethernet-based communication, engineers should take into consideration the protocol that the device will require for embedded applications. A device can transmit data over Ethernet using an Ethernet TCP/IP, EtherNet/IP, or PROFINET connection or emulated Ethernet over a USB connection.

4. Integration Space

Integration space within turnkey systems is precious real estate. Every component in a system has its place, but the more efficiently that space is used, the smaller the footprint of the overall machine. Many embedded imagers are designed with constrained and geometrically-complex spatial requirements in mind. When choosing an embedded device for an application, it is very important to understand the integration space to find a device with the proper mechanical envelope and optical envelope to read each barcode or perform inspections reliably.

Mechanical Envelope

The mechanical envelope is the physical space required to accommodate an imaging device in relation to the barcode or part for inspection. Mechanical envelope takes part orientation into consideration as well as several other spatial requirements, including mounting, three-dimensional space allotment, and cable routing. The essential question is: How much physical space must the imaging device occupy in order to read a code or inspect a part reliably?

When evaluating mounting options for embedded devices, first take the time to note the characteristics of the barcodes or parts and their physical substrate. If, for example, barcodes are on a highly reflective surface, an imager may need to be mounted with an angled bracket to avoid specular or direct reflection from the barcodes, which can “blind” the camera. Additional factors to consider are the lighting environment and the level of contrast between the dark and light elements of a 1D or 2D code or the pixels of an image. Appropriate lighting plays a critically important role in any application, ensuring even illumination for obtaining a consistent wave pattern signal (for laser scanners) or a clear image (for camera-based barcode imagers or machine vision cameras). Many data acquisition devices designed for embedded applications have an integrated light source, such as built-in LEDs, saving space where external lighting would otherwise be required.

One should also plan for the routing of cables when embedding a device. Some devices have their communication cables designed to exit the corner of the housing (as opposed to the back or side). These cables are commonly called corner-exit cables and provide engineers with the greatest number of cable routing options. Corner positioning also conserves space to create the tightest fit possible, flush against inner surfaces of the machine. It is important to keep in mind that the bend radius of cabling should be as large as possible and extreme dynamic flexing should be avoided in devices for embedded applications.

Optical Envelope

While it is critical that data acquisition devices be compact enough in size and scale to physically fit the available dimensions of the integration space, even more important is the space required for these devices to capture images (data). Simply because a barcode reader or machine vision camera fits into a particular space does not guarantee that it can read barcodes or correctly inspect parts presented to it at any size, orientation, or distance. The total dimensional space required by a particular device to decode a symbol or inspect a part at a specified distance is called its optical envelope (also sometimes called the “read” or “inspection” envelope).

The challenge when reading barcodes or inspecting parts at close range is achieving a field of view large enough to span the entire symbol or large enough to capture an object of interest.

Device size, mounting angle, and the distance from the device to the part all comprise the optical envelope and directly affect how much space must be available within a machine for a specific device to perform data acquisition tasks with reliability and repeatability. Since each device’s optics are slightly different, the required distance between a device and part will vary from unit to unit. Devices with smaller optical envelopes have the advantage of requiring less physical space between the device and the symbol or part to be inspected, minimizing the overall mechanical footprint.

The size of the optical envelope is calculated by the length of the data acquisition device, the read angle, and the distance between the device and the barcode or part. The length of the device is easily determined by measuring the actual physical size of the device hardware. For barcodes, the read angle is important because it directly determines the width of the reader’s field of view (what the reader can “see”). The optical envelope also includes the required distance between the front of the device and the barcode or part. Again, since each device has different optical characteristics, this distance will vary. Field of view and read distance can typically be found in a document detailing a device’s technical specifications.

In barcode reading, it is also important to take into account the density (or width of the narrowest element) of the barcode. Typically the higher the density of the barcode, the shorter the read distance. For instance, if a barcode reader needs to read both a 10 mil and a 5 mil barcode at the same distance, the reader will need to have an optical envelope that allows the reader to “see” the 5 mil barcode in high enough resolution given read distance.

An additional optical component is the device’s focal range. Camera-based devices may be equipped with built-in autofocus technology that ensures reliable inspection and decoding regardless of distance from the part. If read or inspection distances change, autofocus imagers can be adjusted from outside the machine using configuration software to ensure the best possible image quality for decoding and inspection.

5. Data Communication Needs

The final thing to know about an application before choosing an embedded device for data acquisition is: how will the system communicate with the device, and how will the device communicate data back to the system? Communication specifications can determine the physical space occupied by the device and its accessories, the speed at which an embedded device must perform, the type of connectivity to the system, and the software used to set up and control the device. These characteristics can be determined by a device’s electrical functionality and software interface.

Electrical Functionality

Power requirements, connectivity, inputs/outputs, and trigger methods all comprise the electrical considerations of embedding a data acquisition device. Many devices are designed with low power requirements in order to reduce the drain on the host instrument. Communication and connectivity options range from high-speed USB and Ethernet to RS-232.

While power requirements are fairly standard, triggering methods can vary greatly. Triggering allows an operator to tell a device when to expect a part or barcode to enter the field of view, or how many scans or images to take of each object. There are two kinds of triggers: discrete (external) triggers and serial triggers. The decision about which type of trigger to use is typically based on preference: programming versus wiring. Discrete triggers are separate sensors, often called object detectors, which can be wired directly into a barcode reader or machine vision camera. Discrete triggers require less programming than serial triggers. Serial triggers are sent from an external device, such as a PLC or host PC, which tells the reader or camera to look for a barcode or perform an inspection. Serial triggers are quite often used in embedded applications to provide more control over an embedded device from outside the machine.

Additional factors to consider are what the device will need to do with the acquired data. Devices for embedded data acquisition can often be designed to perform basic external electrical functions such as communicating with an auxiliary device, driving a relay that trips a gate or a light stack, or sounding an alarm for an unreadable code or rejected part. These factors must all be considered when determining the electrical functionality of a device for embedded operation.

Software Interface

Once the hardware setup for the data acquisition device is defined, the engineer should determine the type of software interface needed to control the device and to achieve optimal data output. Barcode readers and machine vision cameras today are capable of more than just interpreting images and outputting data. Instead, these devices function like independent computers with their own algorithms and processors, reducing the amount of programming required on the device to process data and putting the power in the hands of the operator to control the imager from outside the machine. Technologies such as embedded web servers allow seamless connectivity to databases or other systems on a network. A smart camera can also be set up via software to make decisions based on inspection data, such as triggering an event or shutting down a process. Software for data communication should be able to initialize the device, check its status, and create a real-time communication protocol between the device, the machine, and the outside world.
