Some Problems of Optimization in Computer Integrated Manufacturing Systems (CIMS)

Abstract

The development of Computer Integrated Manufacturing Systems (CIMS) is the most important trend of modern technology. The most important subsystems of those are: the manufacturing process planning; production scheduling; manufacturing process control; transport and manipulation; measurement; technological service.The paper analyzes the solution of the design problems of subsystems from the standpoint of total system optimization. The different levels (subsystems) have complicated interconnections. The optimal parameters on one level effect the constraints on the other levels.The real nature of these connections has been shown for scheduling and cutting data determination. In the earlier papers of the author [2,3] an effective method was proposed for optimal cutting data determination. It has also been shown that this relatively simple problem is deeply connected with the total system performance.The so-called secondary optimization method has been proposed to realize management (scheduling) requirements at cutting data determination. In such a way, an example has been presented when the connection of subsystems may be cleared up and a closed solution obtained.In a rather complex approach, the multicriteria optimization methods and expert systems may be applied.
