Problems solved by technology

[0005] From the above research, it can be seen that in the distribution of conventional orders, most of them take the minimum cost as the objective function, and solve the model by improving the algorithm, but the solution process of the algorithm It takes a long time. In emergency orders, more vehicles are used to use the remaining vehicle resources in the distribution center or the vehicles that have completed the delivery task are returned to the distribution center to carry out the delivery of urgent orders in the form of special delivery, resulting in high delivery costs

Abstract

The invention discloses an emergency order delivery scheduling optimization method. The method comprises the following steps: 1, establishing a conventional order delivery model taking the minimum delivery total cost as a target function; 2, on the basis of the conventional order delivery model established in the step 1, building an emergency order delivery model with the minimum insertion cost based on a time axis strategy; 3, designing an SI heuristic algorithm and dynamic insertion algorithm solving model, and applying the SI heuristic algorithm and dynamic insertion algorithm solving model to the emergency order delivery model obtained in the step 2 to perform delivery scheduling optimization of emergency orders. By performing instance verification on the two-stage model and the algorithm, the result shows that the two-stage model has the characteristics of feasibility in processing emergency orders, high timeliness in order delivery and quick response.

Description

technical field [0001] The invention relates to the technical field of vehicle intelligent optimization scheduling, in particular to an emergency order delivery scheduling optimization method. Background technique [0002] With the rapid development of social economy, the demand for logistics has increased sharply, which has effectively promoted the rapid and efficient development of the logistics industry; the logistics industry is a composite service-oriented industry integrating transportation, warehousing, information technology and other related industries. An important part of the national economy, it has the function of improving the economic structure, enhancing the quality of the national economy and the ability to resist risks; with the rise of e-commerce and the improvement of the degree of individualization of consumer demand, the requirements for the timeliness of logistics distribution have also been significantly improved; In logistics distribution, the planni...
