LEAP (Logistics Effectiveness Analysis Process) Vis-a-Vis SESAME (Selected Essential-Item Stockage for Availability Method)

摘要

It is possible to compute the quantity of spare parts needed for aviation weapons systems by two different models, the Logistics Effectiveness Analysis Process (LEAP), and the Selected Computer Essential-Item Stockage of Availability Method (SESAME). SESAME is detailed, complex, and somewhat difficult to use correctly while LEAP is simplistic and easy to use. It was desired to know how the results of the models differed and a comparison of the two models was performed. Even though both LEAP and SESAME can compute spare parts requirements, they do so with different underlying assumptions. The spare parts computation of each model depends on at least one parameter which is not used in the other model. Using sample data, it was possible to vary those parameters, so that the spare parts requirements computed by the models were somewhat similar. However the similarity of the results depends on the manipulation of the parameters, not necessarily a fundamental similarity of the models. Keywords: Provisioning; Replenishment Spares; Computations.
