There is a general desire of many stakeholders in the product supply and value chain (from designers to users and recyclers) to enable the seamless flow, tracing and updating of information about a product, after its delivery to the customer and up to its final destiny (decommissioning, deregistration and EOL) and back to the designer and producer.
A closed-loop PLM system allows all the actors who play a role during the lifecycle of a product (managers, designers, service and maintenance operators, recyclers, etc.) to track, manage and control product information at any phase of its lifecycle (design, manufacturing, MOL and EOL), at any time and any place in the world.
the main elements of the closed-loop PLM concept and requirements are:
- use of smart Product Embedded Information Devices (PEID)
- local (short distance) connection mode for product data and information exchange
- internet (long distance) product information and knowledge retrieval
- data and information flows
- decision support software.
in PROMISE, 20 partners from 9 European countries have participated in industrial applications from various sectors such as railway, heavy construction equipment, automotive, brown goods, and white goods.
the PROMISE System Architecture
the purpose of the PROMISE architecture is to provide a secure infrastructure for the exchange and processing of product lifecycle management data throughout all lifecycle phases, but with a particular emphasis on improving the accessibility and usability of lifecycle data during the middle-of-life (MOL) and end-of-life (EOL) phases.
the PROMISE architecture defines standards, interfaces and components. These allow the creation of a PROMISE implementation in a flexible and reliable manner.
the PROMISE architecture supports the development of innovative new technology components, yet at the same time allows the integration of existing technologies and systems to form a consolidated infrastructure that creates a flexible medium for the collection, processing and exchange of lifecycle data. It is designed to support and encourage the flow of lifecycle data between multiple enterprises throughout the life of a product and its components.
there are a variety of systems, technologies and products that can participate in PROMISE, and, using PROMISE architecture, interfaces and technologies, can exchange product life cycle data, thus closing the life cycle information loop. In PROMISE, the Internet is the main medium for communication between the different information sources, no matter if they are Product Data and Knowledge Management (PDKM) systems, Decision Support Systems (DSS), Product Embedded Information Devices (PEID) or some other source. These different information systems can be grouped together under the concept of a 'node', whose internal implementation is not critical so long as it is capable of communicating using the PROMISE Messaging Interface (PMI). The PMI is a key interface which enables a web-services based approach, permitting any PMI-enabled user to exchange data with another. Depending on the complexity of any specific application, this can be achieved on a simple peer-to-peer basis if the two users are known to each other, or on a more complex wide-area basis using advanced PROMISE Data Services (middleware). The PROMISE connectivity model is similar to that of the Internet itself. Where the Internet uses the HTTP protocol for transmitting HTML-coded information mainly intended for human users, PROMISE uses PROMISE Messaging Interface (PMI) for transmitting XML-coded information mainly intended for automatic processing by information systems. It is important to understand these relationships because PROMISE in effect proposes an extension to the Internet itself.
