Job-Shop Sequencing Real Life Problem With Setup Time

Abstract

In this paper, we analyzed the sequencing situations on two machines where the machinesetup time is not independent of processing order.A real case study of Hadhramout Industrial Company Complex, Mukalla, Yemen is takenas a model. Data is collected and analyzed using MS-Excel by different methods. The problemformulation has been presented. Multiple solutions were obtained by applying sequencingmethods. The comparison of different solutions is done to choose the optimal solution. Thetime is reduced by 23% to perform the group of jobs and the setup time is reduced 30.5% aswell as the mean flow time is reduced by 30.5%.
