Abstract: The manufacturing industry plays a significant role in the economic development of a country. Efforts are being made to address complex issues and improve the functioning of the manufacturing sector. Job shop relates some such intricate problems as it handles a variety of jobs with varying demand. The current study involves improving the overall production process in a job shop handling several components. Any job shop problem involves sequencing and scheduling of incoming jobs. The study was organised into the three phases, the first phase relating to sequencing of jobs in a job shop for which a priority dispatching rule (PDR) was developed using technique for order preference by similarity to ideal solution (TOPSIS) method. The second phase involves the development of a discrete event simulation (DES) model of the press shop in order to compare the performance measures of various PDRs. The final phase deals with the development of an active production scheduling algorithm that can generate an active schedule for a job shop. All these three phases need to be integrated for better, optimised solutions as they are all interdependent.
