Lean Improvement Of Car Sunroof Assembly Line And Optimization Of Operation Assignment

Automotive sunroof assembly line is a typical mass production assembly line,and this kind of assembly line for production capacity and production beat requirements are very high,the production of a high degree of lean also has a greater demand.In this thesis,according to the specific research target of the automobile sunroof assembly line,it has carried out a detailed field research and data record,and strive to restore the actual field production of the research object.And based on the theoretical method of lean production to improve it,so that the target assembly line to maximize production capacity,waste minimization.Based on the data of field research,this thesis first uses the theoretical method of industrial engineering to analyze the on-site production status of the research object,process analysis and process priority relationship analysis.Make initial lean improvements to the unreasonable processes,processes,etc.that exist at the production site.Make the automobile sunroof assembly line conform to the idea of lean production theory,make its process operation standardized,production on time.After the preliminary analysis and lean improvement of the car sunroof assembly line,it is necessary to solve the waste of uneven distribution of workload in the current production line.Based on the data of field research and the actual working status of automobile sunroof assembly line after the initial implementation of lean improvement,a mathematical model is established to describe the problem of uniform distribution of vehicle sunroof assembly line workload.According to the characteristics of mathematical models and the characteristics of solving problems,a variety of group gene interaction algorithms are designed to solve the established models in order to arrive at the theoretical numerical workload allocation scheme.After combining the intelligent algorithm to find out that the work conforms to the distribution scheme,in order to further analyze the feasibility of the distribution scheme under the actual production constraint conditions and the comparative evaluation of the distribution scheme under different circumstances,this thesis uses the system simulation technology to simulate the distribution scheme in different situations in the actual production state according to the simulation under the fault state.And combined with the actual production status to give a reasonable distribution plan.The overall work research goal of this thesis is to improve the operation process of the car sunroof assembly line by leaning,and to optimize the workload allocation of the car sunroof assembly line,so that the balance rate and production efficiency of the car sunroof assembly line can be significantly improved...
