An urgent order logistics scheduling method for the iron and steel industry

Abstract

The invention relates to an urgent order logistics scheduling method for the iron and steel industry. Firstly, in response to the urgent order pick-up demand, steel companies judge whether to allocate idle warehouses for urgent orders according to the number of warehouses and their activation status. Secondly, in view of the situation of no idle warehouses, an emergency order pick-up strategy is designed and constructed to minimize the pick-up space The optimization problem with the goal of maximum pick-up time is to ensure priority pick-up of urgent orders while reducing the scheduling time of regular orders as much as possible. The beneficial effect of the invention is that it can efficiently deal with emergencies of urgent orders, make reasonable scheduling strategies in time, and improve the risk resistance ability of logistics operations of steel enterprises.

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
