<Background and Purpose>

We carried out this study to present an improved methodology for selecting the authorized stockage lists (ASLs) so that they can capture actual demand with greater accuracy. We also sought to contribute to developing the logistics policy for a future environment.

   ◎ The Army needs to improve its methodology for selecting items on the ASL for the following reasons.

      － As the primary indicator of performance, the accommodation rate of ASL has been so low in recent years that it has fallen short of the Army’s management standards.

      － Selecting the wrong items for an ASL can degrade the combat readiness and operational availability of military equipment and increase their cost of maintenance.

   ◎ We sought to propose improvements to the methodology for selecting the ASL so that resources may be used more efficiently in a future logistics environment.

<Research Results>

We proposed the following improvements to the methodology for ASL selection using predictive techniques and simulations.

   ◎ The concept of an ASL should move away from the one currently understood in the Army and toward a new one that is centered on the formations that need the items that are on the list (an approach across the entire joint force).

   ◎ We also proposed an improved technique for selecting the ASL,

      － taking into consideration factors such as an effective combinatorial search, predictive technique, and costs (inventory, backorder, etc.). 

   ◎ Adopting our proposal may also require certain institutional improvements.

      － The ASL selection timeline needs to be adjusted. An automated selection system needs to be introduced.

      － ASL selections need to take place using the most recent data. Proposed changes need to be implemented gradually through the use of pilot runs.
