An Intuitive Application of Cost Risk Analysis to a LRFS

Methods and Models II Track



This presentation explains the implementation of an Uncertainty Modeling Capability (UMC) into a USMC LRFS. Similar to Life Cycle Cost Estimate (LCCE), the Logistics Requirements Funding Summary (LRFS) captures Integrated Logistics Support (ILS) related costs for a program throughout its life cycle. The LRFS provides visibility of logistics requirements for Program Objectives Memorandum and budget submissions. Additionally, it helps to plan and quantify requirements, identify and defend funding, and serve as the ILS input to the LCCE.

The purpose of including the UMC is to provide an intuitive process for logisticians to produce uncertainty adjusted LRFS estimates. The logistician can use the UMC to report uncertainty-adjusted outputs at varying confidence levels for improved budgeting and decision making. The UMC uses a simulation engine that is entirely Microsoft Excel based. All statistical analysis is performed by Excel functions and all simulation, allocation, and phasing processes are performed by Visual Basic for Applications. Using the LRFS child element point estimates and a user designated Coefficient of Variation (CV), the UMC provides the uncertainty-adjusted outputs. The default CVs are determined in the UMC based on a program’s maturity, USMC risk standards, POPS 2.0 CV Standards. The user can further customize the CVs based on qualitative confidence levels (i.e.; low, medium, or high). The UMC models each child level element’s total program cost as a lognormal distribution.
