Abstract

The invention provides an aisle layout method, comprising the following steps: (1) establishing a mathematical model aiming at minimizing material handling costs; (2) obtaining an initial population; The hybrid algorithm updates the population; (4) updates the population; (5) repeats steps (3)-(4) for a predetermined number of times; (6) the population individual with the highest objective function value in the output population is the optimal solution. The present invention fully considers the actual constraints of the site, integrates the genetic algorithm and the flock algorithm, and on the basis of establishing a more accurate mathematical model of the overall layout of the workshop, realizes the multi-objective solution of the precise layout model and improves the solution accuracy. Considering the influence of the change of logistics interaction points in the horizontal direction of the aisle sideline on the aisle layout and the total cost, according to the characteristics of the problem, a mixed integer programming model conforming to the characteristics is constructed to effectively reduce the total logistics handling cost of the workshop.

Description

technical field [0001] The present invention relates to the technical field of workshop layout, in particular, to an aisle layout method. Background technique [0002] In order to gain a competitive advantage, the manufacturing industry pays more and more attention to high-efficiency and low-cost production, and the facility layout problem exists in many types of manufacturing and service systems, such as the layout of production workshops in the manufacturing industry, the layout of office areas in the service industry, and both sides of the hospital corridor Reasonable layout of clinics and wards is directly related to operating efficiency and operating costs. Therefore, facility layout issues have received extensive attention in manufacturing, service industries, and academia. [0003] The workshop layout problem refers to the layout of equipment and facilities in a given space, and the corresponding constraints are met, and the optimal objective function value is obtain...
