On-site management is to plan and control the on-site activities of on-site personnel, organizations and leaders, and make full use of personnel, materials and equipment resources to ensure a clean environment, complete equipment, timely production, orderly logistics, leading cost and high-quality products. The production site is the carrier and foundation of the enterprise's production system, which directly creates value for the enterprise and is the most active place for the enterprise. The active production site is the most exposed place, and it is also a field management problem that is often ignored.

There are too many hidden and huge wastes in our work field: waste of manufacturing, waste of repair, waste of operation, waste of processing and moving, waste of transportation time, waste of repetition and so on. This audacious waste not only affects the production cost, product quality and safety work efficiency of enterprises. In view of this waste, it is the most effective way to keep the best production site and improve yourself through the site.

Based on the theory of lean production, this paper comprehensively uses the relevant technical methods of industrial engineering and lean production, discusses the qualitative and quantitative analysis of the system, summarizes the company's production site on the basis of the system, clarifies the improvement activities in production line layout, logistics, procedures, line balance, etc., and analyzes and optimizes the waste and non-elimination activities, so as to improve the comprehensive value of workshop production efficiency, fundamentally reduce production costs and enhance the competitiveness of products, which is of great significance to the future of this enterprise and other related enterprises.
