Abstract
In recent years some of the models for Economic Lot Scheduling Problem (ELSP) have been extended to incorporate Just-in-Time (JIT) concepts, by allowing setup costs, setup times and capacity, to be decision variables. All these models result in some forms of cyclic schedules. Hall (1988) proposes “cyclic scheduling for improvement” as a central theme under Just-in-Time and recommends a continual “cycle time analysis for improvement”. This paper presents expanded economic lot scheduling models based on Common Cycle Policy under the framework of “cycle time analysis for improvement”, and proposes a step-by-step procedure for such an analysis, using the various models. The procedure is illustrated with a numerical example.
