Common Shop Stock Lists for the Army's Ground Brigade Combat Teams : RAND Corporation , May 1 , 2025
From the report: “Analysis of the current shop stock lists (SSLs) across each of the Army’s ground BCT types revealed that there was very high variability in the SSLs across units supporting the same equipment, both in terms of breadth and depth. Up to 40 percent of units did not have SSLs (e.g., inventory levels on ten or less parts). The analysis further revealed that where appreciable SSLs were set, the performance was poor (10 percent or less) in terms of filling all parts on high priority workorders both overall and when limited to work orders for critical equipment.
The goal of this research was to dramatically improve performance to better support readiness of critical equipment, while still enabling unit mobility on the battlefield and reducing workload and cost required to conduct periodic SSL updates. Like common authorized stockage lists (CASLs) it was determined that units that support the same equipment would all use the same SSL, referred to as a common SSL (CSSL).
The CSSLs were derived using two key changes. First, the demands across units supporting like equipment were pooled to increase the sample size used to compute inventory levels. Second, the algorithm was changed from a two-step heuristic approach to mathematical optimization. Together these two changes when simulated against actual demands led to increases in shop stock fill rates for maintenance significant parts (MSP) from 5-10 percent for current SSLs to 30-35 percent for the updated CSSLs.”
