General Loss Function Applied to Satellite Scheduling Optimization

Abstract

Satellite imagery utilization is an oversubscribed problem and therefore requires optimum scheduling methodology to maximize the use of the systems. There are many methods to determine performance of a scheduling algorithm, many of which rely on comparison to already established standards. Based on Taguchi s quality loss function formulation that was developed for the manufacturing industry, four general quality loss functions are presented. These loss functions show the dollars lost when two different performances are changed. The two examined are (1) system response time to user image request and (2) total number of image requests satisfied. The general loss function is applied to the satellite scheduling problem to associate losses captured by the algorithm into a common unit, dollars lost. These loss functions, once developed, help decision makers determine how best to utilize their systems in terms of expected bottom line value to the company.
