. As no open-source solver outperforms CPLEX, this study demonstrates the power of commercial linear programming software. CLP was found to be the top performing open-source solver considered in terms of capability and speed. GLPK also performed well but cannot match the speed of CLP or CPLEX. lp_solve and MINOS were considerably slower and encountered issues when solving several test problems.4

This document represents the results of Task 1 (Requirements Elicitation) in Phase 2 of the Contingency Contractor Optimization project. The aim of the overall effort is to create a tool for the contingency contractor element of total force planning during the Support for Strategic Analysis (SSA). The goal of Phase 2 is to develop an electronic storyboard prototype of a tool for use in conjunction with the strategic planning framework of the SSA that can be used for communication with senior decision makers and other strategic contract support stakeholders.The requirements presented here are those on which the electronic storyboard prototype developed in Phase 2 were based, and are also intended to be the basis for the functional tool to be developed in Phase 3. 4 ACKNOWLEDGMENTS
