Real-time Allocation of Multi-Type Production Resource with Due Date grouping for MTO Manufacturing

Abstract

The simultaneous n-type resource allocation method SRAR2 was improved both in the computational time and the optimization levels in this study. The computational time becomes less than 1 second for the actual resource allocation problem of three types of resource and of 2 months demands (# decision variables:157440, wafer test process). SRAR2 and due-date oriented dispatching such as EDD (Earliest Due-date first) achieved the best performance as the result of supplemental effects.
