An Milp Formulation for the Scheduling of Multiproduct Pipeline Systems
نویسندگان
چکیده
Pipelines provide an economic mode of fluid transportation for petroleum systems, specially when large amounts of these products have to be pumped for large distances. The system discussed in this paper is composed of a petroleum refinery, a multiproduct pipeline connected to several depots and the corresponding consumer markets that receive large amounts of gasoline, diesel, LPG and aviation fuel. An MILP optimization model that is based on a convex-hull formulation is proposed for the scheduling system. The model must satisfy all the operational constraints, such as mass balances, distribution constraints and product demands. Results generated include the inventory levels at all locations, the distribution of products between the depots and the best ordering of products in the pipeline.

Optimal scheduling of multiproduct pipeline systems using a non-discrete MILP formulation
Multiproduct pipelines permit to transport large volumes of a wide range of refined petroleum products from major supply sources to distribution centers near market areas. Batches of refined products and grades are pumped back-to-back in the same pipeline, often without any separation device between batches. The sequence and lengths of such pumping runs should be carefully selected in order to ...
متن کاملAn Improved Optimization Model for Scheduling of a Multi-Product Tree-Like Pipeline
In the petroleum supply chain, oil refined products are often delivered to distribution centers by pipelines since they provide the most reliable and economical mode of transportation over large distances. This paper addresses the optimal scheduling of a complex pipeline network with multiple branching lines. The main challenge is to find the optimal sequence and time of product injections/deli...
متن کاملA New Continuous-Time Formulation for the Scheduling of Single Stage Batch Plants with Sequence Dependent Changeovers
This paper presents a new multiple-time grid, continuous-time mixed integer linear program (MILP) model for the short-term scheduling of single stage, multiproduct plants featuring equipment units with sequence dependent changeovers. It considers combined processing and changeover tasks as opposed to handling them separately and is very versatile in terms of type of objective function that can ...
متن کاملDynamic scheduling of multiproduct pipelines with multiple delivery due dates
Scheduling product batches in pipelines is a very complex task with many constraints to be considered. Several papers have been published on the ubject during the last decade. Most of them are based on large-size MILP discrete time scheduling models whose computational efficiency greatly iminishes for rather long time horizons. Recently, an MILP continuous problem representation in both time an...
