Summary The focus of this work will be the continued development of a software system for the modeling and simulation of flow of supplies through a logistics combat network, and the use of this simulation to predict adequacy of the network to meet sustainment requirements on rate of delivery of supplies to ground combat elements. The software will be used to both design the logistics network and to assess the effect of equipment and personnel random attrition rates during the course of the operation. The Year 1 effort has produced a software simulation system which is capable of modeling a network of ground nodes (logistics elements) connected by “connectors” which typically are a set of trucks, but could also be air or sea vehicles. The objective node is the ground combat element (GCE). The GCE and the intermediate nodes have a requirement that the various supplies required for the mission (e.g. fuel, water, ammo, food) never fall below user-specified levels. The software simulates the flow of these supplies through the network versus time, and predicts the levels of supplies at all nodes. Currently, the software requires as input a large number of planning factors, such as the number of ground nodes, the distance between them, the number and speed of trucks moving between nodes, the loading and unloading rates for the trucks, and the rate of consumption of supplies by the nodes. During the course of the operation, the ability of the network to meet the sustainment requirements on supplies can be jeopardized by the loss of availability (attrition) of both personnel and equipment. This loss of availability can be due to both planned (e.g. routine maintenance) and unplanned (unplanned maintenance and combat-related random events). The logistics simulation will be used to predict the robustness of the logistics network in its ability to meet sustainment requirements with the loss of availability of equipment.
