ATLAST Deployment & Push Pack Spares Optimization Module
This paper describes the technical features of the Aircraft Total Life-Cycle Assessment Software Tool (ATLAST) developed by Clockwork Solutions for the military aviation communities and particularly focuses on forecasting life-cycle maintenance and logistics impacts associated with spare parts decisions and on Readiness-Based Sparing (RES) optimization. The capabilities developed within ATLAST have been derived from analysis requirements gathered from recent initiatives in military transformation, recapitalization and Performance-Based Logistics (PBL). World-class business organizations have successfully used high-fidelity life-cycle SPAR™ models to reduce ownership cost and increase availability of capital assets such as fixed and rotary wing aircraft, tanks, radar, submarine combat systems, power plants, chemical plants, and gas exploration and production facilities. Knowing a system’s life-cycle characteristics and future behavior in advance enables decision makers to assess the cost-effectiveness of utilization, logistic support and engineering improvements scenarios before they are implemented. However the ability to perform accurate what-if analysis to forecast costs and readiness in several instances is only a precursor to an effective decision support system. Initial provisioning of spares, spares replenishment and maintenance scheduling decisions are all characterized by an astronomically large set of possible scenarios, with each scenario yielding a different performance level. For these types of problems, quick and accurate decision support systems will include a systematic process of ‘optimization’ that reduces an astronomically large number of scenarios to a manageable set of the most-effective options to be considered for further analysis.
