Abstract


This paper presents a simulation-based scheduling tool which assists production planners in Zimbabwe to generate optimal production schedules, quickly react to unexpected events and give customers more accurate delivery promises. It was noticed that a cable manufacturing company suffered a lot by failing to meet customer due dates as a result of using manual static scheduling techniques which are inadequate to use in such a dynamic environment. The proposed system employed discrete-event simulation modeling as a means to evaluate the sequencing rules and then use tardiness and flow times as performance measurement parameters in order to select one optimum rule. The objectives pursued include developing the description of processes document, designing a simulation model for the plant operations, designing an information system and performing experimental designs of the simulation model. A user friendly excel interface was designed so as to retrieve data from Arena and present it in a more comprehensive manner. 2 sets of  experiments were done under different conditions and the Simulation based Scheduling system was developed. The system is recommended for use by small to medium cable  manufacturers in Zimbabwe.
