AbstractPurpose -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. The purpose of this paper is 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 (IRTD) system for production scheduling control is presented accordingly. Both of the scheduling and ordering performances are integrated into the days of inventory 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 constant work in process 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 information, based on which manufacturers can make correct and timely decisions in solving dispatching strategies and ordering selection within an integrated information system.

A Generation and Repair Approach to Scheduling Semiconductor Packaging Facilities Using Case-Based Reasoning

“…This implies that there is no polynomial-time algorithm that can solve the problem efficiently [13]. For solving the scheduling problem while reducing the computation time and implementation efforts, rulebased methods have been still widely adopted [14], [15], [16]. However, it is difficult to devise a single well-performing rule whenever new scheduling problems are given.…”

Learning to Dispatch Operations with Intentional Delay for Re-Entrant Multiple-Chip Product Assembly Lines

“…In particular, simulation-based studies have attempted to understand the characteristics of lot flows by performing tasks virtually in advance [6,13,[15][16][17][18]. Case base reasoning Utilization [31] Artificial neural network Flow time [32] Utilization [33,34] There is another line of research that aims to control lot flows by using dispatching rules [4,[19][20][21][22][23][24]26]. Dispatching rules have been widely used in various areas because they have the advantages of short computation time and ease of implementation [35,36].…”
