Simulating Material Handling Alternatives for Automotive Machining Processes 780669

This paper describes a technique for developing a computer simulation model of automotive machining processes comprised of machines, conveyors, overhead monorails, and the parts that flow through this system. Employing the discrete-event modeling features of the GASP-IV simulation language, this technique requires that the modeler (a) describe the process configurations in terms of its elements (machines, conveyors, and monorails), (b) provide data inputs that describe the characteristics of each of these elements and define their relationships to one another, and (c) provide data inputs that give the simulation conditions. The model then simulates a prescribed duration of production activity and produces both statistical and graphical reports in terms of production output and operational efficiency. Analysis of simulation trials involving several proposed process configurations, including alternative modes of material handling, enables the selection of a preferred design.
