| PLM Concept Set - What Everybody Needs To Know by Roger Tempest |
|
|
I was asked about PLM knowledge by a manager at a $2bn US company. With striking use of the vernacular, he wanted to know: "What are the PLM fundamentals, that if we don't follow, somebody should slap us?"
The PLM Standards Workshop in Oxford generated the answer - the 'PLM Concept Set'. These are the definitions and principles that everyone needs to know in order to understand PLM correctly.
By lunchtime on the second day the Workshop had the drafts of a number of standards that could be written up and published. However, would it be sufficient just to print them out and hand them to somebody, and expect that person to be able to apply them? You would need to know some basic fundamentals about PLM in order to understand how and why the standards are likely to work in your company. Almost everyone who has worked in PLM for some time knows these concepts implicitly, but they have never been formally defined.
PLM managers, vendors, integrators and consultants all speak the same "PLM language", and share some vague kind of common experience, but what is it that experienced PLM people know that someone new to the role would not? Obviously, you need to be able to explain what you are working on, so the Concept Set begins with two standard definitions:- PLM; and the relationship between PLM and PDM. You need to appreciate that PLM always acts on the business from an enterprise context; to be able to know how far PLM has progressed through your current organisation; and to know how much effect it has on your business.

This involves three concepts:-
Finally you need a standard definition for the future PLM state that you are aiming for: PLM Maturity; and for the best way of getting there: PLM Best Practice. It is important to note that the PLM Concept Set is not "rocket science" - it is merely the embodiment of fundamental PLM ideas into an industry standard grouping. Its value lies in formalising, in a very simple way, a standardised base point for PLM expertise. As well as creating a common PLM language, standards also enable accurate analysis of PLM issues that were previously thought too difficult to resolve. The Oxford Workshop defined a new standard for Product Structure, which for many companies is an area of massive complexity. When the PDM Definition from the Concept Set is combined with the primacy of 'As-Designed' data from the Product Structure, many spurious viewpoints of the PLM-ERP scenario are discounted. This makes the picture much simpler and paves the way for a PLM-ERP standard later in the year. The PLM Concept Set is published on the PLMIG web site, and the Product Structure Standard is contained in the Q1 2010 issue of the PLM Journal.

| CL2M Case Study 1 : End of Life Vehicles by David Potter |
|
|
The ELV (End of Life Vehicle) directive (EU/2000/53) introduced by the EU in 2000 addresses pollution arising from vehicles that have reached the end of their useful life. The directive specifies thresholds for the reuse, recycling and recovery of materials from ELVs.
By 2006 the ratio of materials in an ELV which should be reused, recycled or recovered was set at 85% of the total vehicle weight. This is set to increase to 95% by 2015. This case study is based on the first of 10 commercial applications developed during the EU PROMISE Project. It showed how information collected during the Beginning- and Middle-Of-Life phases of a private passenger vehicle could be used to improve decision making and materials tracking, contribute to the achievement of the ELV targets and influence new product design:
The primary focus of this application scenario was to enable a licensed vehicle dismantler to make:
The application flow is as follows. On arrival at the dismantler the vehicle is deregistered and its ownership is transferred to the dismantler and processing instructions are provided.
The vehicle is identified by a top-level Product Embedded Information Device (PEID), which will indicate basic information; the type of vehicle, its ID, the assembly date. Mission profile information, and statistics about the use of the vehicle and components (such as kilometres travelled, average humidity, external temperature and temperature in the engine area), are accessible. History of all maintenance activity, and of replaced parts (and their corresponding dates) is also available. |
Components and subsystems that are worth reusing or remanufacturing are identified by and according to the information and work instructions downloaded from the back-end system, the PROMISE PDKM (Product Data Knowledge Management) system and its associated PROMISE Decision Support System (DSS).
Components and assemblies that are removed are identifiable through information stored on a local PEID. Besides the ID, information such as the manufacturing date, installation date and material code is available. Summaries concerning use, environmental conditions, history of maintenance activity, and the list of replaced parts and corresponding dates, are accessible. Routing instructions to the recycler/remanufacturer are made available.
The vehicle is tracked until the shredder. After reaching the shredder the vehicle is permanently deregistered and statistics are updated. The amount of information captured depends on the type of component concerned. Parts for re-manufacture will require more information than parts for recycling. Closed-Loop Lifecycle Management (CL2M) ensures that the traceability of, and accountability for, materials can be assured through the processing of the relevant information gathered during all phases of the vehicle’s life.
The primary business benefit of this application is to turn legislative threats to the business into an opportunity, establishing a used parts business model for a major motor manufacturer and its affiliated agents. The use of whole-of-life lifecycle information increases the effectiveness of decision making regarding the re-use or recycling of components and enables regulatory requirements to be met. The design and implementation of this application was in accordance with the PROMISE Architecture. The existing vehicle ECU (Electronic Control Unit) was exploited and enhanced as the top-level PEID. Vehicle components - such as clutch, alternator, starter motor and battery - were enabled with local PEIDs in the form of RFID tags with re-writable memory. PROMISE Data Services (middleware) was used to link the PEIDs with the back-end PDKM and DSS systems.
Readers who are registered at cl2m.com will be able to access the full public text of this PROMISE demonstrator case study by following this link: Case Study 1: End of Life Vehicles. There is no charge for registration. In the next issue of the 2PLM newsletter, I will present the second in this series of case studies, dealing with the application of PROMISE technologies to engine remanufacturing for heavy construction machines.
