Crude oil tank farm scheduling method

Abstract

The invention discloses a crude oil tank farm scheduling method which can accurately and rapidly provide a comprehensively-planned and comprehensively-optimized scheduling scheme for tank farm scheduling. According to the method, the aim of looking for the optimal working route by supporting a designated device which is sure to be passed by and a designated device which cannot be passed by under the constraint conditions such as tank farm devices and pipeline real-time states and by taking the shortest path as the optimization target is considered. By means of the method, enterprise operation cost is greatly lowered, production accidents caused by human subjective judgment are reduced, work safety of a crude oil tank farm is guaranteed, and the scheduling level and the economical efficiency in the tank farm are improved.

Description

technical field [0001] The invention relates to the field of scheduling of crude oil tank farms in refining and chemical enterprises and warehousing and logistics companies, in particular to a method for quickly finding an optimal scheduling operation path, and in particular to a scheduling method for crude oil tank farms. Background technique [0002] At present, the large and medium-sized crude oil tank farms of domestic refining, chemical and warehousing logistics companies generally have problems such as a large number of storage tanks, complex process pipelines, and wide distribution of tank farms. The scheduling decision of tank farms mainly depends on the subjective experience of dispatchers. It is difficult to take into account the conditions of all process equipment, such as pipeline occupancy, the current status of valves and pumps, etc., which often results in low operating efficiency and increases the operating cost of the tank farm.
