Deterministic models of inventory control
Webderivations in the following make the usual assumptions of deterministic inventory models. That is, the annual demand, D, is constant; the lead time, L, is either zero or constant and known; the reordering cost, 5, does not change with inflation; the unit purchase cost, C, is subject to inflation; the annual carrying rate, i, remains constant; The Economic Order Quantity (EOQ) model is the most basic of all inventory models that helps inventory manager answer the question “how much should I order”?. This model is based on the philosophy of determining an order quantity where the sum of the ordering costs and the carrying costs is minimal. See more Following are some of the assumptions made in deriving an equation for an EOQ: 1. We consider a single item in the inventory system. The demand for this item is known and is … See more Let us now derive an expression that will help us determine an economic order quantity that answers the question of how much to ordergiven that the assumptions listed above are satisfied. We consider a planning horizon of … See more We can use another method to determine the TIC once we have the EOQ. If we ignore the annual purchasing cost in Eq. 3.7, we have Substituting the value of Q from Eq. 3.8 in Eq. … See more Let us now examine the physical dimensions involved in the EOQ equation (Eq. 3.8): 1. The demand, D, is expressed in terms of number of units per year. 2. The ordering cost, … See more

Webin job-shop-systems. Here, the inventory evolutions are outcome of discrete objects, dependent processes and re-entrant structures resulting in often highly volatile developments [14], [15]. The inventory developments are discrete in time and value although between two changes of inventory the value remains constant forming a quasi … WebEven when inventory models are restricted to a single product the number of possible models is enormous, due to the various assumptions made about the key variables: demand, costs, and the physical nature of the system. The demand for the product may be deterministic or stochastic; it may completely predictable, or predictable up to some
