Optimal Scheduling of Flowshop Batch Process for Zero-Wait and No Intermediate Storage Transfer Policy

Abstract

The scheduling zero-wait (ZW) and no intermediate storage transfer (NIS) policy of multi-product batch processes in order to produce a number of low volume high value-added chemical products because of its economic impact. It involves various parameters such as makespan (completion time) which is recognized as one of the important design parameter as it helps to decide for the best scheduling design and normally used as the main parameter for selecting the optimal production sequence which involves various parameters such as batch process recipes, sequence of production and transfer policy for product intermediates. In this paper, we present a development, solution and computational performance evaluation of optimal scheduling for multiproduct batch process with two commonly used transfer policies namely zero wait (ZW) and no intermediate storage (NIS) by using computer program language software (Java) which simplify and improve the determination of Makespan and select the optimum sequence due to the minimum Makespan.
