Displan: A Multiproduct Plant/Warehouse Location Model With Nonlinear Inventory Costs, Ronald H. Ballou Nov 1984

Displan: A Multiproduct Plant/Warehouse Location Model With Nonlinear Inventory Costs, Ronald H. Ballou

Research Reports from the Department of Operations

DISPLAN is a large-scale computer model used for the strategic planning of physical supply and distribution networks. This planning may involve determining the number, size, and location of plants, warehouses, inventories, terminals, and similar facilities. Although several mathematical models address this problem, a unique feature of DISPLAN is its handling of nonlinear inventory costs. The proper economic analysis of network designs requires balancing all relevant costs to achieve the minimum cost configuration of facilities. These costs include facility inbound and outbound transportation costs, facility fixed costs, warehouse storage and handling costs, order processing costs, and inventory carrying costs. Accurately describing …

Distribution System Design: A Problem-Solving Approach, Mohammed Ali Chowdhury Hakim Aug 1982

Distribution System Design: A Problem-Solving Approach, Mohammed Ali Chowdhury Hakim

Research Reports from the Department of Operations

This paper presents a methodology for designing an effective two-echelon multicommodity distribution network. Addressing key logistics issues, such as warehouse location and product distribution, the model integrates cost and service trade-offs, regional warehousing practices, and shipment alternatives. Unlike previous models, this approach offers comprehensive problem representation and accurate cost structure, enhancing solution quality and flexibility. Using a linear programming (LP) approach, it generates solutions within 3% of the optimum for all tested cases. Comparative evaluation against existing models highlights its superior problem representation, computational efficiency, and analytical versatility. The study emphasizes the importance of a global consideration of design alternatives …

Synthesis Of A Crude Oil Supply System: A Non-Convex Network Problem, Samuel Jackson Mathis Aug 1972

Synthesis Of A Crude Oil Supply System: A Non-Convex Network Problem, Samuel Jackson Mathis

Research Reports from the Department of Operations

This problem involves the synthesis of a system to supply crude oil to refineries by transporting it in tankers that travel on various routes of a network. The costs involved are non-convex, which is assumed to mean that they are sufficiently non-linear to preclude approximations by convex functions, and specifically includes the possibility of integer-valued functions and fixed costs. The problem was inspired by considerations of a crude oil transshipment system, but the resulting formulation is sufficiently general to include many types of network problems with non-linear flows or costs, which can be discretized.
