The inventory management can help enterprises accurately predict production demands, reasonable inventory management and purchasing planning are carried out according to market demands, the enterprises can avoid excessive backlog of finished products, reduce capital occupation, and reduce inventory cost while maintaining supply, so that supply chain efficiency is improved. The water-based paint is particularly sensitive to temperature and humidity environments, and the quality of the water-based paint is extremely easy to be influenced by storage environments, so that the water-based paint is more important to the inventory management.
Currently, the existing water paint inventory is to stack the packaging barrels to ensure that space utilization is maximized, and because the paint is stacked together, the monitoring line of sight is blocked, and if the stacked paint is not properly marked or classified, the risk of confusion or misuse may be increased. In addition, the lack of analysis of the amount of inventory safe storage, the market demand being floating, the lack of a reasonable analysis of the amount of inventory safe storage may lead to an unbalanced supply and demand situation. When the quantity of the stock safety storage is insufficient, market demands cannot be met, potential sales opportunities are lost, and when the quantity of the stock safety storage is excessive, stock backlog and price reduction sales can be caused, and profit and enterprise competitiveness are further damaged.
On the other hand, the inventory purchasing plan of the existing production enterprises depends on sales data more, and there are some limitations in this way, one of the main problems is that the problem of storage loss caused by poor storage conditions in the storage process is neglected, and the poor storage conditions can cause the quality of goods to be reduced or damaged, so that a part of inventory cannot be sold on time, further the storage loss of the enterprises is increased, and meanwhile, the after-sales service cost caused by quality problems may be increased due to the inconvenience of environmental monitoring conditions.
