2018year 3In the middle of the month, the safety stock and procurement-related knowledge learning organized by the procurement, quality, technology and other relevant departments of the President Yin organized, let everyone have a new understanding of safety stock, and no longer limited to the narrow scope of guaranteeing the safety stock of production. It is the inventory prepared to prevent uncertain factors (such as a large number of unexpected orders, delays in the delivery of raw materials and other special reasons) on the basis of ensuring normal production. On the one hand, safety stock reduces the possibility of stock-outs, but on the other hand increases the risk of inventory backlog, which does not meet the requirements of lean production. To ensure a reasonable safety stock level is determined by the cooperation of production planning, purchasing and marketing departments, and the safety stock is dynamic. This new concept can be used by employees in their future work, combined with theory and practice, to improve our work efficiency, and improve the company’s operational efficiency and quality. I believe that in future work, everyone can have new ideas in this field. Progress and breakthroughs.
