An Integrated Approach to Modeling Distributed Manufacturing Control and Human Operators
نویسندگان
چکیده
Manufacturing systems are experiencing several trends which are increasing the importance of the control system as a component of the overall manufacturing system. Among these trends are increased levels of automation, increasing differentiation and customization of products, and increased demands on system performance. A control system must coordinate the various activities of a manufacturing operation so that requirements and performance goals are met. Most manufacturing control systems are distributed in nature and incorporate both computerized controllers and human operators. There are few generic modeling approaches, however, which represent interactions between these manufacturing control entities. This research proposes a modeling approach which synthesizes a generic architecture for modeling computerized manufacturing control and the operator function model (OFM), a methodology to model operator actions and tasks in complex systems. This approach is based on an underlying client-server representation and has the potential to facilitate design and prototyping of manufacturing control systems.

This paper proposes a new integrative view of manufacturing cell formation and both inter-cell and intra-cell layout problems. Cells formation and their popular bi-directional linear layout are determined simultaneously through a Dynamic Programming algorithm (with the objective of minimizing the inter-cell flow cost under a cell size constraint). This Dynamic Programming algorithm is implement...
