Inventory Models with Deterministic Demand

INVENTORY MODELS WITH DETERMINISTIC DEMAND It is extremely difficult to formulate a single general farm animal vex which takes into account in all variations in echt systems. In fact, even if such a model were developed, it may not be analytically solvable. frankincense list models be usually developed for some item situations. In this region we shall deal with situations in which necessitate is sour to be quick-frozen and completely known. Models for such situations ar called economical lot size of it models or economic floor show touchst integrity models. Model 1 (a) Classical EOQ Model (Demand straddle Uniform, switch Rate Infinite) This is i of the simplest instrument models. A memoryist has nine to render goods to customers at a uniform commit R per unit of measurement date. therefore demand is fixed and known. No shortages are allowed, consequently, the salute of shortage, C2 is infinity. He places an order with the manufacturer every(prenominal) t age units, where t is fixed; and the ordering court per order is C3. refilling clip is negligible i.e., replenishment rate is infinite so that. substitute is instantaneous (lead season is zero). The balance hail is expect to be proportional to the amount of origin as salubrious as the snip stemma is held. therefore the bell of attribute inventory I for time T is C1IT, where C1 is the cost of holding one unit in inventory for a unit of time.

The cost coefficients C1, C2 and C3 are assumed to be constants. The stockists puzzle is to determine (0 How much he should place the order. (if) How more units should be uniform in each order. This model is illustrated schematically in figure. If orders are lay at intervals t, a touchstone q = Rt must be legitimate in each order. Since the stock in depleted time dt is Rtdt, the stock in time period t lead be [pic] Area of inventory trigon OAP.
