Inventory Model Of Taking Account Of Partial Payment And Capital Time-Value

Material inventory in human production, economic, military and other socialactivities are essential, Because it overcomes the material production andconsumption in time differences, created the time value of goods, guarantee theinterflow of commodities and production run smoothly, However, too much stockmaterial and led to a vast pool of liquidity occupied, for social reproduction of thenegative impact，Therefore scientific, reasonable and effective stock managementand control to improve the enterprise and social economic benefits are verybeneficial，The traditional demand mode of economic order model assumption thatall expenses involved and time is irrelevant, While in the world economy appeargenerally greatly inflation today，Funds of real value is ever-changing, So face thetime-varying demand, inventory system in inventory management decisions shouldnot be ignored cost of inventory decision-making influence minim, In addition,ordering fee, inventory keeping, shortages fee and metamorphic charges incurred atignore expenses of duration circumstances, is constant, but take the cost intoconsideration of duration, it is a variable. In this paper。 on the basis of formermade the following progressive research, mainly completed the work are asfollows:(1) consider funding duration, consider metamorphism, initial and end theinventory of zero, and inventory when completed, supplement the instantaneousallowable stock-out, but the last cycle is not allow shortages occur, and the formerone cycle of shortage completely default to next cycle beginning supply under theconditions of the corresponding mathematical model was established, and discussesthe inventory system is the existence and the uniqueness of the solution, find theoptimal storage strategy, reveals the pay of inventory system lags behind theoptimal storage strategy influence.(2) in the model, the lagging pay considering two of the most common situation(a) buy fare from items arrive after a period of fixed system lags behind the timepay one-time teams, and (b) to pay a certain proportion of some articles premiums,had not been paid premiums can lag period of fixed time paid again, models arepresented the optimal solution of the necessary condition and algorithm. Through aalgorithm that control model of solving process (3) Based on the allowable stock-out and Que Liang can completely deep-lyingconditions, establishing a hysteretic payment model, and gives out the model ofoptimal solution the necessary condition of existence, and gives the model simplealgorithm of.Finally, summing up the study, points out the deficiencies and future researchdirection...
