Combat Service Support System Timing Study.
Abstract
This report describes a study conducted to forecast the number of hours required to process the personnel, logistics, and maintenance software systems for a division using the Combat Service Support System (CS sub 3) IBM 360/30 hardware configuration under average to maximum workloads. These systems and their component subsystems range in state of development from the conceptual to operational, requiring use of separate forecasting methodologies based on the life cycle of the software. For the personnel system, linear regression techniques were used to predict runtimes based on expected volumes of input and output. A simulation model was constructed using the Computer Aided Systems Evaluation (CASE) package to predict runtimes for the logistics system. Runtimes for the maintenance system were predicted by CASE simulation and by analyst estimates. The conclusion of this study is that the CS sub 3 hardware system will be adequate under average workloads but may become saturated under maximum workloads. Several proposals which should lower the computer time requirements below the saturation levels are discussed.
