Job and Tool Scheduling for Flexible Machining Cells

Abstract

A flexible machining cell (FMC) consists of several highly versatile numerically controlled machines. FMCs typically machine a wide variety of parts and require a corresponding wide variety of cutting tools. Systems comprised of one or more FMCs are the fastest growing class of flexible manufacturing systems. This paper addresses the problem of generating a job and tool schedule for an FMC with identical machines. Schedule quality is a function of job completion times (as measured according to the weighted flow time criterion) and tool movement where the relative importance between these two potentially conflicting performance measures can vary from problem to problem. A heuristic procedure is proposed and evaluated in a experiment that draws on data from industry.
