Stellenbosch University. Faculty of Engineering. Dept. of Industrial Engineering. Production scheduling -- Data processing Machine-shop practice Hours of labor -- Data processing Dissertations -- Industrial engineering Thesis (M. Ing.) -- University of Stellenbosch, 1991. The problem addressed in this thesis is to schedule multiple jobs on multiple machines in a maintenance job shop. The scheduling problem is classified with the aid of a classification scheme for scheduling problems and their models, based on literature mainly from 1980 onward. A survey of solution methods for the scheduling problem has shown that optimal solution methods are not feasible for solving practical job shop problems. Instead a heuristic solution method based on a priority rule was used to solve the scheduling problem. The priority rule used is a composite rule which uses information on initial job priorities, processing times, number of remaining operations, number of operations waiting at the next machine, and the remaining slack time. The solution method was implemented on a micro-computer and tested with actual workshop data. The computer generated schedules resulted in improved mean flow time and weighted tardiness compared to the hand schedule. Other advantages of the computer generated schedules are: -Cost savings through less in-process-inventory, meeting of due dates, and improved materials procurements planning, and -Accurate feedback to clients on job completion times. Before the proposed scheduling system can be implemented successfully in a dynamic scheduling environment, a data management system needs to be implemented in the workshop under consideration.
