What is the average time‚ in weeks between orders? EOQ = (2DS)/H EOQ = (2*20000*40)/2 EOQ = 800000 EOQ = 894.43894 TBO = (EOQ/D)*52weeks TBO = (894/20000)*52weeks TBO = (0.0447)*52weeks TBO = 2.32442.32weeks 2.

not inventories in the Nigeria Bottling Company‚ Ilorin Plant can be evaluated and understood using the various existing tools of optimization in inventory management. The study methods employed include the variance analysis‚ Economic Order Quantity (EOQ) Model and the Chi-square method. The answer to the fundamental question of how best an organization which handles inventory can be efficiently run is provided for in the analysis and findings of the study. Consequently‚ recommendations on the right

2 EOQ Model The first model we will present is called the economic order quantity (EOQ) model. This model is studied first owing to its simplicity. Simplicity and restrictive modeling assumptions usually go together‚ and the EOQ model is not an exception. However‚ the presence of these modeling assumptions does not mean that the model cannot be used in practice. There are many situations in which this model will produce good results. For example‚ these models have been effectively employed

One such policy is ordering ECONOMIC ORDER QUQNTITY for stock replenishment at this point holding cost reduces significantly and total annual inventory cost is lowest. Though maintaining exact EOQ is sometime not possible working in the vicinity of it results in lower total annual inventory cost. Holding cost is straight line that is it directly varies with ordering quantity

Case Report: Jamie CHANG 1. Based on the assumption that all data collected are accurate and the methods used to collect are reliable‚ the EOQ calculations are correct. Given by the EOQ model‚ the optimal Q (quantity of an order) is set by the equation Oopt=[2(Demand Rate)(Order Setup Cost)/(Holding Cost Rate)]^(1/2). In this case‚ order setup cost=setup hours per order × setup cost per hour; holding cost rate= 30% × product unit cost. 2. Jamie Change only shows the optimal inventory levels for

Question 1: Using the EOQ methods outlined in Chapter 9‚ determine how many kegs of nails Low should order at one time. Question 2: Assume that all conditions in Question 1 hold‚ except that Low’s supplier now offers a quantity discount in the form of absorbing all or part of Low’s order-processing costs. For orders of 750 or more kegs of nails‚ the supplier will absorb all order-processing costs; for orders between 249 and 749 kegs‚ the supplier will absorb half. What is Low’s new EOQ?

economic order quantity (EOQ) is the order size that minimizes total annual cost So to respond to the criticism whish say that EOQ models tend to provide misleading results because values of D‚ S and H are at best educated guesses‚ we should explain that first of all the holding cost (H) instead to computed they are determined by management; that’s why the EOQ should be an approximate quantity. In addition as we saw in class that the total cost curve is relatively flat round the EOQ. In other words if
