Enhanced product lifecycle information management using "communicating materials"
Résumé
With traditional PLM (Product Lifecycle Management), people think towards the future: first comes product development, then manufacturing, then support and finally disposal -- data flows only in forward direction. With the CL2M (Closed-Loop Lifecycle Management) concept, there are also flows going backwards, enabling better visibility and control of the product throughout its PLC (Product Life Cycle). CL2M uses "intelligent products" to gather information at any instant of the PLC and to make it available on downstream or upstream PLC phases. However, information is often deported on a database and is accessed remotely via a network pointer carried by the product. To bring the CL2M concept a step further, this paper addresses a dual challenge: i) providing a new kind of intelligent material capable of undergoing physical transformations without losing its communication ability and the data that is stored on it, ii) providing a framework to achieve a high degree of data synchronization (i.e. enabling data updates on the product, regardless of the network availability). An applicative scenario is presented, showing how this kind of material is put into practice in the context of "communicating medical garments" and how the requirements of the desired degree of data synchronization can be reached.
