A Combined Inventory And Delivery Model For Repairable Items, Bahtiyar Eren Mar 2000

A Combined Inventory And Delivery Model For Repairable Items, Bahtiyar Eren

Theses and Dissertations

Traditionally, logistics analysts have treated the delivery problem separate from the inventory and repair problems. In other words, each of these three problems-delivery, inventory, and repair-are treated individually. We combine the vehicle routing problems and inventory allocation problems in a single formulation. Furthermore, lateral re-supply is considered, in that supplies are not only available from the main depot, but also from other bases. After we get the lateral re-supply information, we set a delivery allocation plan out of the main depot. Such allocations are then delivered via vehicles stationed at the main depot. There is a repair capability for each …

Multi-Objective Evaluation Of Target Sets In A Logistics Network, Paul D. Emslie Mar 2000

Multi-Objective Evaluation Of Target Sets In A Logistics Network, Paul D. Emslie

Theses and Dissertations

This thesis addresses the selection of target sets to disrupt an adversary's logistics network in a wartime environment. In the presence of many objectives--such as reducing maximum flow, lengthening routes, avoiding collateral damage, all at minimal risk to our pilots--the problem of determining the best target set is complex. Previous efforts have not adequately considered the value of the remaining network functionality after target destruction. In addition, current network targeting procedures optimize target sets with respect to only a single metric. This thesis uses a multi-objective decision analysis framework capturing actual targeting decision-maker values and preferences to evaluate and analyze …
