Research On Optimization Of Inventory Management Of Q Company

Inventory management is the core content of logistics management,the third power source for the development of manufacturing enterprises,and the key and difficult point in enterprise management,so it is of great practical significance to study inventory rationalization of manufacturing enterprises.Special equipment boiler is the "heart" of thermal power plant,and it is an indispensable equipment in manufacturing industries and social life.With its more and more extensive application,it has been related to the development of national economy.The research object of this paper is the inventory of Q company,a heavy manufacturing enterprise that produces boiler parts for special equipment.Through on-the-spot investigation,it is found that there are some problems in the inventory management of Q company,such as unreasonable inventory classification,low level of inventory management and so on.And the causes of these problems are analyzed.Most of the inventory number is high,a small part of the time,the total inventory is too high,and the inventory cost is high.These problems directly affect the daily business activities and reputation of the enterprise.Aiming at the inventory management problem of Q Company,this paper puts forward six improvement methods,including establishing information technology platform,establishing standardized management system,joint inventory management method,ABC classification method,economic order batch method,and(s,S)inventory strategy.In this paper,the research focuses on quantitative optimization,and the inventory items of Q company are classified by ABC classification after reorganization,and the A inventory is quantitatively optimized.For the inventory with seasonal demand and large consumption under the stable external environment,an economic batch order model with allowable shortage and normal replenishment is constructed by considering the factor of capital occupation fee.For the essential inventory with stochastic demand,considering the factors of safety inventory and capital occupation fee,an economic batch ordering model with no shortage and replenishment in Poisson distribution is constructed,and the actual consumption of inventory is expressed in integral form.For the discrete inventory with sharp drop in demand during the continuous impact period of sudden major public events,considering the actual situation,the(s,S)discrete inventory model with inventory strategy is constructed to optimize it.After the calculation of the above model,the inventory cost is reduced by 7% ～ 10% compared with that before the improvement,and the optimization result is ideal,reaching the expected goal of this paper.It is concluded that using scientific methods to carry out inventory management can help enterprises reduce costs and improve profits,which can provide reference for inventory management and emergency reserve work of the same type of production enterprises and has practical reference significance.
