The production and supply chain system of auto parts companies must cooperate with OEMs to ensure quality and delivery requirements. With the intensification of competition, car companies are constantly pursuing leaner management to cope with market challenges, and high-end customers have also put forward higher requirements for quality, cost, and delivery time. Therefore, it has become a difficult problem for auto parts enterprises to provide the best quality accessories at a reasonable price and effectively improve the manufacturing delivery capability and cost control ability.
In terms of production, auto parts companies have many production types and complex product configurations, and the formulation of order scheduling and production plans is relatively complicated. Due to the long procurement cycle of raw materials or the change of host demand, the cost of raw materials for auto parts factories is relatively high. At the same time, due to the long production cycle and frequent delivery, customers need to track the production progress at any time, and auto parts companies need to balance the operating load capacity of the equipment.
In terms of quality control, most customers have stricter requirements on product quality, and need to quickly and accurately trace the product production process, so that when a problematic product is found, the scope and cause of the quality problem can be quickly identified. In addition, due to the compact production line and limited space, the quantity and practice of material distribution are more accurate, and the stock of WIP is minimized.
In response to the above problems, auto parts companies have adopted MES management system solutions.
First of all, when formulating the production schedule, it is necessary to consider factors such as the shelf life of materials, semi-finished product inventory, combined production of products of the same mold, priority capacity constraints, delivery constraints, and day and night shift priorities. Secondly, through scientific scheduling and real-time monitoring, it is possible to effectively manage workshop sites such as shift handover, waste collection, production machine allocation, and machine pick-up and return, and achieve management goals that cannot be achieved by empirical scheduling. In addition, the system feeds back the production status in real time, realizes on-site process control and monitoring of material information, process information, equipment information, and defective rate in the production process, and displays the production site status in real time through production visualization interface, visualization, and electronic kanban management Information, improve equipment energy efficiency, and ensure that production progress is carried out as planned.
In terms of equipment management, the MES production management system collects equipment operating status, automatically records equipment start-up and downtime, calculates equipment utilization, and provides a complete breakdown of the location and cause of downtime events. Real-time calculation and generation of equipment production utilization rate, mechanical efficiency, predictive maintenance, point inspection, maintenance, repair the whole process, and form a report on the maintenance status of equipment, realize automatic maintenance prompts and performance evaluation of equipment, provide equipment maintenance, Arranging maintenance plans, controlling the health of equipment, and providing a basis for production scheduling, thereby greatly improving the comprehensive utilization of equipment and promoting continuous improvement of production efficiency.
In terms of quality inspection, after the MES system of auto parts enterprises is launched, the corresponding batches of materials and batches of semi-finished products are input during the inspection process, and the system automatically captures the inspection data. Code binding production batches, remote monitoring of production quality, fast traceability of the source of quality, real-time warning of defects, strict quality control, comprehensive control during the quality inspection process, and more accurate data.
In terms of traceability management, the MES system of auto parts enterprises collects, counts, tracks, warns, and analyzes various data in the whole process of parts production, and records the data of the first inspection and sampling inspection of each production in the system one by one. , When there is a problem with the quality of a certain part, it can be traced back to the detailed parameters, which is convenient for the staff to check, analyze the problem in time and solve it in time. Each component product is equipped with a unique barcode or number, effectively establishing a product quality traceability system.
In terms of inventory management, warehouse management involves the control of raw materials, semi-finished products and finished products. Through the implementation of the MES system, the warehouse goods are controlled by boxes, and the warehouse management is carried out through PDA scanning codes. At the same time, ERP documents are automatically generated to complete bookkeeping. Work.
