The concept of a real-time enterprise in manufacturing: Design and implementation of a framework based on EDA and CEP

Abstract

Enterprises have to react instantly to changing market conditions and disturbances that occur during execution of value creation processes. Depending upon the processes' context, the goal is to significantly reduce lead times, reaction times, and time-to-market, among others. The vision of a real-time enterprise (RTE), which is able to sense and analyze events from internal and external sources, and perform adequate (re-)actions, has been envisaged by manufacturing enterprises. Daniel Metz presents a framework based on EDA and CEP towards the realization of RTE in manufacturing. The framework closes the vertical integration gap, and further, establishes feedback in (near) real-time among enterprise levels. As such, the framework provides a holistic and closed-loop control of (manufacturing) processes, and encompasses results and insights from management, engineering, and computer science. The framework has been implemented for a small and medium sized foundry in Germany. The developed control approach has led to a significant increase in (manufacturing) processes' efficiency (i.e., performance, quality, and availability).
