Variable-speed scheduling method and system for mixed transportation of crude oil in long-distance pipeline

Abstract

The invention discloses a variable-speed scheduling method for mixed transportation of crude oil in a long-distance pipeline. The variable-speed scheduling method aims at the problems that a traditional manual production scheduling scheme in the long-distance pipeline mixed oil transportation process is low in efficiency and large in time delay of the long-distance pipeline oil transportation, theoriginal established production scheduling scheme cannot be used during transporting oil with variable speed according to the actual production situation, and proposes a variable-speed production scheduling system with self-adapting variable-speed oil transportation of mixed transportation of crude oil in the long-distance pipeline, and the production scheduling scheme can be independently generated after user configuration without manual intervention. Compared with a commonly used mixed integer programming method, the method is small in calculation scale, high in solving speed, low in probability of no solution and less in computing resource occupation; at the same time, according to the method, the problem that the original production scheduling scheme cannot be used after changing theoil transportation speed in case of the long-distance pipeline existing in the oil transportation process is solved; and the production efficiency of enterprises is improved, the loss of the enterprises is lowered, and the economic benefit is improved.

Description

technical field [0001] The invention relates to the field of production scheduling of refining and chemical enterprises, in particular to a variable-speed scheduling method under the condition of long-distance pipelines, and in particular to a variable-speed scheduling method for mixed crude oil transportation of long-distance pipelines. Background technique [0002] At present, in the daily production of refining and chemical enterprises, the scheduling work is often done manually, and it is difficult to find the optimal scheduling scheme in consideration of all the rules, so people often use the mixed integer programming method combined with the solver to find the optimal Scheduling scheme, but the mixed integer programming method has a large calculation scale, often consumes 2-3 days of calculation time, and there is a high probability that there will be no solution. At the same time, when there are long-distance long-distance pipelines in the oil transportation process, ...
