A Development of Multi-Purpose Agricultural Fertilizer Package Scheduling Plan with Dynamic Demand and Period of Time

Abstract

Currently, the Chemical fertilizer industry of agriculture faces backorder and charges from unsuccessful delivery of goods. The researcher studies the problem and presents this research with the objectives. to design the fertilizer packing schedule to suit the customers' unstable behavior of picking up products. The researcher has studied the work process and analyzed the customer's pick-up behavior.

The result of the research showed that the developed scheduling concept able to reduce the amount of backorder by 0.89%, which can reduce the backlogged fee commission up to 12.07% per month, reduce backlog produce by 6% - 52% per month and increase machine utilization rate by 7.68% per month.
