Emergency order logistics scheduling method for iron and steel industry

Abstract

The invention relates to an emergency order logistics scheduling method for the iron and steel industry. The method comprises the steps that firstly, aiming at emergency order delivery requirements, an iron and steel enterprise judges whether to distribute idle warehouses for an emergency order according to the number of warehouses and a starting state; and secondly, aiming at the condition that no idle warehouses exist, an emergency order queue-jumping delivery strategy is designed, and an optimization problem with a goal of minimizing the maximum delivery duration of a delivery location is constructed, so that conventional order scheduling time is shortened as much as possible while delivery of the emergency order is preferentially guaranteed. The method has the beneficial effects that emergency situations of emergency orders can be efficiently dealt with, a reasonable scheduling strategy can be timely made, and the logistics operation risk resisting capability of a steel enterprise is improved.

Description

technical field [0001] The invention belongs to the field of iron and steel logistics dispatching, and in particular relates to an urgent order logistics dispatching method for the iron and steel industry. Background technique [0002] The high-quality development of the steel industry is an important cornerstone to promote the rapid rise of my country's infrastructure, and it is also an important part of promoting the prosperity and stability of the national economy. However, due to the lag of supporting technology updates, the current steel industry has shortcomings such as weak innovation drive and insufficient risk resistance capabilities. The upgrading and transformation of iron and steel enterprises requires them to be able to integrate warehousing, logistics, and informatization, and to fully ensure the orderliness of production scheduling in the face of emergencies. Urgent orders are a frequent situation faced by iron and steel logistics outbound operations. This ty...

Problems solved by technology

However, when confronted with urgent order vehicles whose priority of picking up goods is much higher than that of regular orders, the logistics dispatching of order vehicles in queue is bound to be hindered

At this time, relying on manpower to formulate a logistics scheduling plan is not only inefficient, but will even greatly prolong the delivery time of some orders and increase scheduling costs
