    Abstract

    With the increasingly fierce competition in the manufactural market, manufactural  companies with production orders as the core have gradually begun to develop in the drction of  multi-variety, variable batch size, cycle shortening, lean production. Due to the lack of a scientifie  evaluation system and sbjective avareness, the tadional way of manning job llocationo results  in people unable to make the most of their work and low production eficiency. Traditional  scheduling mcthods are dificult to obtain optimal scheduling plans under muliple constraints  due to limited manual computing apbilie. Therefore, this paper takes the mulisilled  personnel scheduling and scheduling method in the MES system of the construction machinery  assembly workshop as the main research objeet and conducts mathematical modeling and  example simulation to verify is benefit maximization. The main rescarch contents are as follows:

    Firstly, Aiming at the problem that the traditional stffing method of the assembly line is  casily ffccted by subjective consciousness and the team leader has limited awareness of  personnel capbilties, it is dificult to oplimize the deployment of personnel and posts. The  procssing data such as time eficiency, pass rate, and completion rate of mouli-skilled personnel  in the assembly process are used as evaluaion indicators, and the entropy method in the objective  weighing method is adopted to detemine the weigh cofficient of ceach evaluation index. This  paper proposes a calculaion method for the competence index of cach skill of muliskilled  personnel. To maximize the total competency index value of the assembly line, the opimizaion  model of muliskilled personnel scheduling is constructed with the constaint of the relationship  of prsonnel and post configuraion. An improved Hungarian algoritm to solve the opimization  model of personnel scheduling is proposed, which realizes the optimization of the deployment of  muli-killed personnel and workstations on the assembly line, Taking the man-post configuration  of the multi-model MCV mie-low assembly line of M company as an example, the simulation  resuls show that the improved Hungary algorithm can ellivcl solve the opimizaion problem of the mut-skilled personnel configurat ion of the assembly line, effectively avoid the waste of  resources, and increase the production fficiency by 10.95%~ 12.86%.

    Secondly, Because of the complex constraints of the mixed-flow assembly line for multi-  model products of construction mac hinery, the limited calculation capac ity of manual production,  it is dificult to obtain the optimal scheduling plan, Through the general description of the  scheduling problem of the mixed-flow assembly line, the optimization goal is to minimize the  maximum cycle completion period of mixed-flow assembly of multi-model products, and the  production scheduling and scheduling optimization model of the mixed-flow assembly line is  constructed. Combining the rapid convergence characteristics of genetic algorithm and the  feature that the Metropolis criterion of simulated annealing algorithm overflows with local  optimality, a genetic simulated annealing algorithm is proposed to solve the scheduling  optimization model of the mixed-flow assembly line, and realize the optimization of production  scheduling of mixed-flow assembly line of multi-model products. Taking the scheduling  arrangement of the muti-model MCV mixe-low assembly line in the construction machinery  assembly workshop of M company as an example, the simulation results show that the genetic  simulated anneal ing algorithm can efetively solve the optimization problem of the mixsed-flow  assembly line scheduling arrangement, and the mixed-flow assembly cycle period is shortened  by 31. 1min~43.7min. The production eficiency is increased by 18.2%~-23%.

    Thirdly, This paper develops the MES system of construction machinery assembly  workshop. From bottom to top, the system is pided into database layer, server layer, data access  layer, business logic layer, user interface layer, and front-end Ul layer. The database layer mainly  conducts dynamic management and real-time update of various data of the system; the server  layer provides top-level support for the normal operation of the system and the interaction of  system software and hardware; the data access layer real izes the informat ion interaction between  the upper-layer business and the lower-layer database by concretizing the business; the business  logic layer mainly processes logic calculation examples for specific functions of the system, and  responds to front-end user instructions promptly; the user interface layer and the front-end UI  layer mainly include modules such as production management, quality management, inventory  management, equipment management, and basic data management. Users only need to select the  functions in the corresponding modules to operate according to their needs, and the business logic  layer will respond in time.

    Key words: Assembly line: competency index; multi-skilled personnel schedul ing; production  scheduling: MES system
