“…Comparing the random and dedicated FMS, some advantages in limiting the variety of parts in each family include minimizing bottlenecks caused by delays in data communication and processing, maximizing pooling of machines and added protection against tool breakage, and streamlining the material¯ow, thus simplifying production planning (Co 1990). Ultimately, the reduction in the variety of parts under a random FMS will lead to a dedicated FMS situation.…”

The literature typically assumes that an FMS consists of a number of machines of diOE erent processing capability. Furthermore, in view of the inherent¯exibility of an FMS, many researchers believe that`¯exible' implies that a wide variety of parts can be, and should be, processed simultaneously in an FMS. To do otherwise will inevitably mean some machines are idle and hence the FMS may become a tremendous waste. This paper is an attempt to study this issue. Unlike a job shop, which is typically an eclectic collection of machines of diOE erent process capabilities, most¯exible manufacturing systems consist of only one or two types of versatile programmable machines. We contend that the FMS machines are analogous to the multi-skilled workers in lean production. In lean production, workers work in teams. It is common for each team to work on one job at a time, from start to ® nish. Jobs are not passed around from worker to worker. Likewise, machines in an FMS can be assigned into`teams', where each`team' is dedicated to process a single part type (or family) at a time. Parts do not necessarily have to move from machine to machine in a job shop manner.

This paper considers the issue of whether to mix part-types in one or several of the families to be produced in ā exible manufacturing system (FMS). For this input control problem in an FMS, we have derived conditions that support the mixing of a part-type, which can share the setup of other part-types, in deterministic environment. The problem is identi®ed as a special economic lot scheduling problem (ELSP), and is formulated as a linear programming problem. Analytical insights are derived by considering the special case with three part-families. The results are illustrated with a numerical example.

Part type selection, machine loading and part type volume determination problems in FMS planning

The solution to subproblems of FMS planning problems require an integrated approach. The mathematical programming approaches, which are often followed, are not suitable for large problems. In this paper, we have proposed a three stage approach to solving part type selection, machine loading and part type volume determination problems. In contrast to the usual approach of maximizing the part types in each batch (or minimizing the number of batches), we have attempted to maximize the routeing¯exibility of the batches. A heuristic has been proposed for the part type selection problem and simple mathematical programs for the other two problems. The illustrative examples show that by improving the routeinḡ exibility of the batches the overall system performance has improved.
