[Abstract]:Based on the detailed analysis of the characteristics of the workshop, this paper takes the workshop of H Company as the research object, and aims at the actual situation of the motor production process and the enterprise. The optimization of the job unit layout in the workshop of this enterprise is studied. The main contents of this paper are as follows: firstly, this paper analyzes and summarizes the relevant literature on the optimization of workshop layout at home and abroad, and makes a deep analysis of the basic theory and methods of the present workshop layout. Then taking the production system of H Company as the object of study, taking the production task of the workshop for half a year as the data, and according to the original data such as the material flow of the workshop and the distance between the operation units, etc. The F-D diagram is used to analyze the logistics system of the current production workshop, and the main problems in the layout of the motor workshop are found out by the analysis diagram. Secondly, aiming at the main problems existing in the workshop at present. In this paper, the relevant theories of workshop layout are consulted and analyzed in detail, and the layout and design objectives of the motor production workshop are determined. A multi-objective mathematical model with minimum handling cost and shortest handling time is established. According to the actual situation of the motor workshop, the constraint conditions of workshop facility planning are put forward. In this paper, the genetic algorithm is used to solve the problem of job-shop layout model. Firstly, the basic principle of the algorithm, the workflow and the advantages of the algorithm in solving the job-shop layout problem are introduced in detail. Then the satisfactory solution is obtained by substituting the relevant data of the motor workshop as the initial optimization scheme for the layout of the workshop. Finally, in order to deeply study the layout optimization problem of the workshop, and to make up for the shortcomings of the algorithm optimization, this paper establishes the simulation model of the motor workshop based on the initial optimization scheme. According to the simulation results obtained from the operation, the layout of the workshop is further optimized, and the optimization scheme has obvious advantages compared with the original layout. The results of this paper can be used for reference in workshop layout of manufacturing enterprises.
