A heuristic procedure for determining the tradeoff between expediting the ordering of materials and delaying the project is presented. The heuristic procedure is a modification of the procedure taken from the literature. With the use of an illustrative example, it has been shown that the modified procedure provides schedules with lower total cost values. Experimental results performed on randomly generated problems reveal that the modification can bring a decrease in total cost values as much as 52%.
