MODIFICATION OF CAPP SYSTEMS FOR CAPP SCHEDULING INTEGRATION

This paper presents a new approach-through the modification of an existing CAPP system, i.e. CMPP-for achieving CAPP/scheduling integration. An operation machine index is developed as a relative measure for selecting the best machine from all the alternatives in the process planning stage to satisfy two scheduling criteria: mean flow time and number of jobs tardy. The software program for implementing the integrated system has been written in C. A sample part is used to illustrate that both the mean flow time and the number of jobs tardy can be reduced with the use of the integrated system.
