Tank field scheduling work flow planning method

Abstract

The invention discloses a tank field scheduling work flow planning method, which comprises the following steps: 1) work flow planning in which a dispatcher appoints a tank field starting device, a passing-through device, and a terminal device and takes the shortest path, the fewest nodes, and the single line / double lines as the restraint conditions with the useable state of the devices being of input state. A network algorithm-extended state task network is used to automatically reason for a number of optimal operating flows; and 2) operating flows reviewing and releasing in which the dispatcher chooses suitable operating flows to be submitted for reviewing by management staff who releases the operating flows after the reviewing of the operating flows. According to the invention, available states and restraint conditions of a tank field are combined and a network algorithm-extended state task network (ESTN) is employed for dispatching flow planning. Compared with the dispatching schemes relying heavily on human experience, this planning method is more objective and reasonable, and can effectively minimize the errors of oil transporting operations in a crude oil tank field and a product oil field, therefore, raising working efficiency.

Description

technical field [0001] The invention relates to a method for planning a tank farm scheduling operation process, which belongs to the field of computer control Background technique [0002] The scheduling optimization of oil transportation operations in the tank farm includes the optimization of crude oil scheduling and the optimization of refined oil scheduling. Crude oil scheduling optimization includes a series of processes such as unloading, storage and transportation, transportation and mixing of crude oil from the arrival of the port to the end of the device feeding. Scheduling optimization of refined oil products includes a series of processes such as unloading, storage, transportation, transportation and mixing of refined oil from the storage area to the storage area. Both crude oil scheduling optimization and product oil scheduling optimization need to make reasonable arrangements for the oil tanks, pipelines, feed quantities, blending ratios and devices involved. ...

AI Technical Summary

Problems solved by technology

[0003] 1) At present, crude oil and refined oil storage and transportation scheduling mostly rely on manual experience and are completed manually. For fluctuations in the entire scheduling process, integrated scheduling optimization cannot be carried out from a global perspective, and various uncertain factors cannot be dealt with in a timely and effective manner. Resulting in high inventory, ineffective use of funds, and increased operating expenses

[0004] 2) Scheduling instructions are sent to the operation team by fax or telephone, which has low execution efficiency and narrow audience
