Abstract

The makespan in multilevel product scheduling is affected by product structure complexity and process routing complexity. This study was a part of long term study in multilevel product scheduling done by Production System Laboratory of UAJY. The objective of the study is to find a short-cut justification of lot size decision giving minimum makespan, based on some parameters of product structure complexity and process routing complexity. This paper presents a preliminary result of the study, i.e. the effect of product structure complexity and setup time-run time ratio (R) on makespan. The analysis was based on a set of hypothetical data. Product structure complexity was limited up to 5 levels and up to 5 parts in one level. Process routing complexity was limited up to 3 machines and up to 5 operations. Forward scheduling was used to compute the makespan. Different R was employed to find the minimum makespan. The R giving the minimum makespan was called optimum R. The result showed that the values of average optimum R varied from 0.198 to 0.455. This study is still underway for analyzing further the effect of product structure complexity and process routing complexity
