Embodiment Construction

[0052] The present invention will be further described below in conjunction with the accompanying drawings and the distribution example in the numerical control workshop.

[0053] Such as figure 1 shown.

[0054] A method for scheduling automatic distribution vehicles in a numerical control workshop, comprising the following steps:

[0055] (1) The delivery center obtains the delivery instruction information. The delivery center refers to the place where materials are delivered in the numerical control workshop. The delivery instruction information includes: user demand, user location and delivery time window required by the user;

[0056] (2) According to the user's location and demand, under the condition of satisfying the load constraints of the distribution vehicles, the matrix scanning method is used to assign the distribution tasks of each user to different vehicles. According to the different scanning starting points, the scanning method generates different Vehicle ta...

Abstract

An automatic distribution vehicle scheduling method in a CNC workshop, which is characterized by: on the basis of constraint analysis and mathematical modeling of the vehicle scheduling problem in the CNC workshop, an original matrix scanning method is first used to allocate distribution tasks to vehicles, which significantly optimizes The initial population of the subsequent genetic algorithm is then used to solve the optimal delivery sequence of a single vehicle. Based on the driving characteristics of the delivery vehicles in the CNC workshop, the original coordinate addition and subtraction method with direction is used to calculate the actual driving distance of the vehicle. On this basis The golden section method is used to obtain the optimal delivery time of the vehicle, and the elite retention strategy is used to avoid the local convergence of the algorithm, thereby obtaining an ideal vehicle scheduling optimization solution. The invention solves the problem of inefficiency of the existing vehicle scheduling algorithm in the CNC workshop due to the specific distribution of user points and the special process of distribution, and the algorithm is efficient and feasible.

Description

technical field [0001] The present invention relates to a kind of logistics technology, especially a kind of logistics distribution technology in numerical control processing workshop, specifically a kind of automatic distribution vehicle dispatching method of numerical control workshop based on matrix scanning, golden section and genetic algorithm, which uses matrix scanning The method assigns tasks to different vehicles and uses the genetic algorithm to solve the TSP (Traveling Salesman Problem, Traveling Salesman Problem) of a single vehicle, and finally obtains the optimal vehicle scheduling scheme. Background technique [0002] In the study of modern logistics distribution, the transportation scheduling problem, which is to effectively control the inventory cost, transportation cost and transportation time in the distribution, has become the core and goal of the research. The vehicle scheduling problem in logistics distribution is to deliver a reasonable quantity of goo...
