An Inventory Model For Deteriorating Items

Under the environment of the coexisting economic model of E-commerce and physical store,and “Supply” Reform,many companies begin to seek for their own developing path,which is to shift production driven rather than market driven.Many companies market research shows that agricultural products often appear slow-moving or deteriorating.According to the annual report of The Ministry of Land and Resources,two or three line of the city’s commercial housing Demand Greater or Overstock.It can’t meet the needs for housing and solve the housing problem,suitably.The phenomenon of agricultural products’ slow-moving or deteriorating indicates that the social needs and the marketing of agricultural products is not entirely consistent.It also shows the importance of planning and developing sales channels.It can be attributed to the Supply Chain Management in Theory.Based on this consideration,this paper mainly discusses an inventory model with deteriorating items.It spread along the main supply integration,which is the “Production-Sales-Transport”.The full text is divided into five chapters to start gradually.The first chapter and the second chapter briefly introduce the selected background and reviews the results of previous studies,and then describe the basic theoretical knowledge and mathematical knowledge.The third Chapter mainly considers an inventory model under time-varying productivity.firstly,an inventory model with learning phenomenon is introduced.As the human learning phenomenon,its operational skills will be more and more skilled.it is the reason why the corresponding to the time of pruductedindividual items will gradually decrease until a fixed time.The study efficiency influence on the optimal production quantity is given by The Numerical Simulation.Secondly,an EPQ model of production side sales under quadratic functional productivity is introduced.It shows that the influence of the replenishment time under the various unit efficiency and the number of labor on the planning cycle.The fourth chapter discusses the inventory models of deteriorating items based on consumer purchase strategy.The optimal selling cycle and initial goods supply under verities purchase strategy are given,and then the sensitivity of the best selling time to other parameters is analyzed.The fifth chapter,a new inventory model under the big data environment is given,combined with the research methods of location problem and routing problem.It mainly considers the impact of transportation costs and customer satisfaction on the path choice of delivery personnel,at the same time,to maximize meet customer demand to pick up,the best delivery point location is given.
