Abstract

Abstract : Purpose: In a complex semiconductor manufacturing system (SMS) environment, the implementation of dynamic production scheduling and dispatching strategies is critical for SMS distributed collaborative manufacturing events to make quick and correct decisions. This paper attempts to assist manufacturers in achieving the real time dispatching and obtaining integrated optimization for shop floor production scheduling. Design/methodology/approach: In this paper, an integrated model is designed under assemble to order environment and a framework of a real time dispatching system (IRTD) for production scheduling control is presented accordingly. Both of the scheduling and ordering performances are integrated into the days of inventory(DOI) based dispatching algorithm, which can deal with the multiple indicators of dynamic scheduling and ordering in this system to generate the "optimal" dispatching policies. Subsequently, the platform of IRTD system is realized with four modules function embedded. Findings: The proposed IRTD system is designed to compare the previous CONWIP method in the experiment, which shows the better performance achievement of the IRTD system for shop floor production dynamic scheduling and order control. The presented framework and algorithm can facilitate real time dispatching information integration to obtain performance metrics in terms of reliability, availability and maintainability. Research limitations/implications: The presented system can be further developed to generic factory manufacturing with the presented logic and architecture proliferation. Originality/value: The IRTD system can integrate the real time customer demand and work in process (WIP) information, based on which manufacturers can make correct and timely decisions in solving dispatching strategies and ordering selection within an integrated information system. Keywords Real time dispatching, Integration, Production scheduling.
