Performance-oriented logistics assessment (POLA) preparing the logistics decision model for use in analysess

This Note explains how to prepare the Logistics Decision Model (LDM) for use in subsequent analyses. This Note depends heavily on the LDM Users' Manual, which should be read first. LDM was developed by the Performance- Oriented Logistics Assessment (POLA) project as part of a larger methodology. Performance-Oriented Logistics Assessment has developed a prototype methodology to help build the logistics portion of the Army five-year program. When building its program, the Army first estimates a requirement for each resource, but the price of satisfying all requirements always greatly exceeds the amount the Army can spend. Therefore, the Army prioritizes the different requirements; it decides which ones will be funded immediately and which ones will be deferred, perhaps for several years. The POLA methodology attempts to estimate the impact on combat performance of alternative investments in logistics resources. Combat performance measures thus become the common scale on which different resources are rated. If an increment of one resource has relatively little impact on combat performance and an equal-cost increment of a second resource has a large impact, the Army may prefer to satisfy less of the requirement for the first resource and more of the requirement for the second.
