A simulation of single-level MRP lot sizing heuristics: an analysis of performance by rule

Abstract

Abstract This paper presents the results of a large-scale computer simulation of 12 of the standard single-level, discrete demand lot sizing heuristics. The authors present the results in 3-D illustrations which depict the performance of these heuristics on 15 individual demand patterns. This information is prefaced by a brief review of the method used to perform the simulation. The performance of each of the 12 heuristics was evaluated for 51 sets of cost parameters for each of 15 different demand patterns. This has resulted in the analysis of 9180 combinations of heuristic, demand pattern, and cost parameters. The authors believe that this, by far, represents the largest digital simulation of single-level lot sizing rules completed to date. During the past two decades, a significant amount of research investigating the economics of lot sizing single-level discrete demand patterns has been conducted. However, many of the conclusions reached by individual research efforts on this subject have differed. At...
