CAREER: Design and Implementation of a Knowledge-Based Agile Manufacturing Information System

Description

In the new and emerging Agile Manufacturing paradigm, where multiple firms cooperate under flexible virtual enterprise structures, there exists a much needed mechanism to manage and control information flow among collaborating partners. In response to this pressing need, this research addresses the design and implementation of an agile manufacturing information system integrating manufacturing databases dispersed at various partner sites. We propose a framework in which: (1) Information is modeled in a hierarchical fashion using Object Oriented Methodology (OOM). (2) Information Transactions are specified by the workflow hierarchy consisting of partner workflows. (3) Information flow between partners is controlled by a set of distributed Workflow Managers (WM) interacting with partner knowledge bases, which reflect partner specific information control rules on internal data exchanges, as well as inter-partner protocols for joint partner communications. (4) The prototype system is accomplished using the World Wide Web based on a Client-Server architecture. The overall approach and system provide within a dynamic environment, where virtual partnerships are synthesized in response to specific business initiatives, a dynamic and flexible mechanism to support partner information exchange.
