The Application Research Of VMI Mode In A Steel Enterprise

As a pillar industry,the iron and steel industry is an important part of the national economy.In recent years,with the change of the global economic development trends and the intensifying competition,the iron and steel industry around the world is under the huge impact.And most of the iron and steel enterprises have fallen profits or even lost in domestic.The steel output of our country is very high,but the domestic iron and steel logistics function is not perfect and in the low operating efficiency.It makes to meet the demand of the development of iron and steel production and trade impossibly.In the iron and steel enterprises,the related purchasing cost and inventory cost occupy a larger proportion in the total production cost.With the development of the market,more and more enterprises,by using the ideas of supply chain management,reduce the inventory cost and improve efficiency and the level of service to cope with the increasingly fierce competition.The inventory management,as an important part of the enterprise management and the supply chain management,causes the attention from the various aspects.There is uncertain demand in the inventory of steel iron and steel industry.And the demand quantity or the available quantity of steel also can influence the price each other.These uncertain factors lead to that the steel ordering cycle and stock holdings are unreasonable,which in turn improves the inventory cost.Therefore,it is of great significance to study the rational inventory management strategy for steel products.The iron and steel enterprise is selected as the research background in this article and the inventory control method of steel is studied.The combination of the impact from Poisson demand on the inventory of a steel company,the steel inventory management method is considered in particular and the inventory optimization model is established based on VMI mode and random demand.The inventory cost including the fixed ordering cost,the holding cost and the shortage cost is analyzed,and the reasonable order cycle and the order quantity are solved ultimately by the improved hybrid algorithms.It is worth noting that building the demand of Poisson distribution model can better reflect the actual production situation.But it also increases the complexity of the inventory model at the same time,which makes the model more difficult to be solved.In this paper,the improved hybrid algorithms are proposed to solve the inventory model respectively.The improved algorithms can improve the efficiency of global optimization.
