The effects of warship and replenishment ship attrition on war arsenal requirements

A three-phase simulation written in Pascal and using a suite of procedures developed by Lancaster University and the London School of Economics is developed to model a group of ships subject to submarine and air attacks during an extended period of conflict. The simulation collects statistics on weapon usage by the ship group in order to study the impact of attrition, including the effects of preferential targeting, and correlation between the usages of different weapon systems, on war arsenal requirements.
