Application of context-aware computing in Manufacturing Execution System

Context awareness is used to design innovative user interfaces to implement precise routing planning and optimal job scheduling and accurate control of the environment in workshop. The purpose of this work is to propose a context-aware Manufacturing Execution System (MES) with background of dynamic and complex production process in workshop. The context-aware architecture as a backbone of MES, with the help of the reference rules of business in workshop can reveal the dynamic interaction properties of system composite units more thoroughly and guide objects specification and abstraction more formally. Event management provides computing environments with the ability to adapt the services or content they provide, by implicitly sensing and automatically deriving the employeepsilas needs from the context of workshop, making services more attentive, responsive and predictive. This paper concerned with the development of an ambient rule based framework that aims to maximize the automation of the complete production lifecycle via the establishment of a flexible prototype of context ontology in workshop. In the end, the MES model is proved reasonable and effective by structure design and realization of an integrated production management system executing in a locomotive enterprise.
