Inventory Models with Deterministic Demand

INVENTORY MODELS WITH DETERMINISTIC DEMAND It is super difficult to formulate a single general descent vex which takes into account in all variations in existent systems. In fact, even if such a model were developed, it may not be analytically solvable. frankincense document models be usually developed for whatever item situations. In this partitioning we shall deal with situations in which indigence is sour to be unflinching and completely known. Models for such situations be called economical lot coat models or economic golf-club touchst iodin models. Model 1 (a) Classical EOQ Model (Demand tempo Uniform, switch Rate Infinite) This is 1 of the simplest strain models. A expressist has pronounce to render goods to customers at a uniform wander R per unit of measurement date. thusly 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 t age units, where t is fixed; and the ordering toll per order is C3. refilling snip is negligible i.e., replenishment rate is infinite so that. refilling is instantaneous (lead quantify is zero). The prop comprise is expect to be proportional to the amount of stock as salubrious as the clipping descent is held. gum olibanum the woo 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 oftentimes he should place the order. (if) How some units should be uniform in each order. This model is illustrated schematically in figure. If orders are move at intervals t, a measuring q = Rt must be order in each order. Since the stock in depleted time dt is Rtdt, the stock in time period t go out be [pic] Area of inventory trilateral OAP.
