Item A conceptual framework for managing petroleum products pipeline(Texas Tech University, 1998-05) Ali, Shahid IbrahimA barrel of cmde oil is transformed into various refined products and these products travel through pipelines before reaching demand points. Refined products shipped through pipelines include various grades of gasoline, kerosene, jet fuel, diesel, and home heating oils. These different products are carried in the same pipeline. Since a multiple product pipeline transports different types of petroleum products, it faces the issue of product mixing. Movement of more than one product in a single pipeline obviously calls for more sophisticated monitoring and control than is required for continuous movement of a single product (Kennedy, 1993). Because of the variety of refined products, it is necessary to segregate them. To achieve the segregation, the refined products are transported in batches, maintaining the integrity of their shipments. Batch size depends upon the amount of interface or mixed products that can be tolerated as the batches move down the line (Wolbert, 1979).Item Integrated inventory problem and vehicle routing problem in one warehouse and multi-retailer distribution system(Texas Tech University, 1998-12) Prutsakul, AnchaleeThe objective of the one warehouse multi-retailer distribution problem is to find replenishment policies that specify delivery quantities, delivery intervals and vehicle routes that minimize inventory and transportation costs. Since each retailer has a different demand, the warehouse has to supply each retailer with different order quantities and replenishment periods. In addition, the warehouse has to decide which retailers can be served by the same route. Thus, to solve this distribution system, we must include both the inventory problem and the vehicle routing problem. This chapter is organized as follows. The inventory problem, which is the EOQ model, will be described first and the classical VRP model will be discussed next. Finally, we present the single warehouse and many retailers distribution system including some general assumptions.
