Developing a computer shop floor control model for a CIM system - using object modeling technique

In this paper, an analyzing process for building a shop floor controller mo del is addressed by using Object Model Technique (OMT). The major objective of the proposed shop floor controller model is to bridge the gaps between the production planning level and manufacturing level in a CIM environment such that production orders can be properly carried out by the shop floor e quipment. In addition, shop floor dynamic conditions also can be fed back t o the planning level. There are three modules in this model. (1) Planning a nd Scheduling Module takes charge of transferring production orders into de tailed manufacturing tasks. (2) Dispatching and Coordination Module issues production commands to the controllers of proper production equipment. (3) Data Monitoring and Analysis Module collects and analyzes shop floor data i n order to identify the shop floor dynamic conditions. An implementation en vironment about the proposed model is also presented in the final part of t his paper. (C) 2000 Elsevier Science B.V. All rights reserved.
