Using Dyna-Metric to Compute Base Level Self-Sufficiency Spares Requirements,
Abstract
This document compares the current system's method to compute Base-Level Self-Sufficiency Spares (BLSS) requirements to the modified Dynamic Multi-Echelon Technique for Recoverable Inventory Control (Dyna-METRIC) computation. The current system computes a fixed safety level requirement. It is not scientific; it does not maximize weapon system performance nor even minimize back orders or costs. In addition, the current system does not consider identure relationships. As a result, the current system stocks unnecessary items, too many of some items, and too few of other items. Dyna-METRIC reduces BLSS requirements cost by $.45 to $51.28 million, while meeting the weapon system support objective. Dyna-METRIC reduces the range and depth of the BLSS without reducing its combat capability. In addition using Dyna-METRIC to compute BLSS means the Air Force will use the same method to both compute and assess wartime requirements. Shown are Dyna-METRIC computed BLSS requirements to achieve a confidence level of 95 percent results in support at least equal to the current BLSS at less cost. The Air Force should use Dyna-METRIC (with a 95 percent confidence level) to compute BLSS requirements. The Weapon System Management Information System (WSMIS) Requirement Execution Availability Logistics Module (REALM) currently uses Dyna-METRIC to compute War Readiness Spares Kit (WRSK) requirements, so AFLC has the capability to begin using Dyna-METRIC immediately. Keywords: Air Force logistics command, Confidence levels, Materiel. (KR)
