Problems solved by technology

[0005] Therefore, MRP and Kanban management have their own strengths and weaknesses. If an enterprise only chooses one of the two as the production management mode of the enterprise, it will inevitably encounter their own defects.

Embodiment Construction

[0070] Kanban composition: Electronic Kanban is composed of header and details (i.e. items). Kanban header is based on order, including demand summary number, process route, sequence, record type, work center, production order number, production order status, etc.; Kanban uses the process as the minimum distribution unit, so the details are based on the process, including specific information such as demand summary number, process route, bench, required materials, factory, inventory location, backflush mark, and material demand time. It meets the requirements of lean production and distribution. In the lean logistics kanban system, the header and details of the kanban are connected through the demand summary number.

[0071] The work center in the present invention includes a production branch factory and a logistics center.

[0072] 1. Kanban generation:

Abstract

The present invention provides a lean logistics system based on kanban, which includes: using parallel processing technology to generate a material demand kanban based on materials in production orders or three-day plans according to process and team information. The present invention calculates as needed The data volume defines 20-30 jobs, defines a job name for each job, and all order processes are cyclically assigned job names according to the defined number of jobs. When running a job, only data with the same name as the currently running job is taken; at the same time , in order to maximize the use of server resources, weights are allocated according to work centers. The weights are proportional to the data volume of the work center and the total quantity; when running to generate Kanban details, due to the large amount of data, the data insertion and calculation of the Kanban are done in the background The job execution calculation means that the time difference between the actual business and the actual business also means that there is discrepancy in data. The present invention adds an operation identifier to the data to be generated on the material demand board.

Description

technical field [0001] The invention belongs to the technical field of motor vehicle manufacturing, in particular to a Kanban-based lean logistics system in the motor vehicle manufacturing process. Background technique [0002] The two major bases for material distribution are MRP and Kanban. [0003] MRP refers to according to the subordination and quantity relationship of the items at each level of the product structure, taking each item as the planning object, taking the completion period as the time basis to reverse the plan, and distinguishing the order of the planned delivery time of each material according to the length of the lead time. It is an industry. In the material planning management mode of a manufacturing enterprise, MRP can help people convert the master production plan into a capacity demand plan, generate a load report, and then adjust the master production plan according to the load report analysis results and feedback, but it should be noted that in the...
