A company operates for 50 weeks a year and uses a fixed quantity inventory system for one of its most important items. Below are the characteristics for the item:
Weekly demand follows normal distribution: mean of 400 units and standard deviation of 100 units Order Cost = $40 per order Annual Holding cost = $2/unit/year Desired service level = 95% (z = 1.645) Lead Time = 4 weeks Economic Order Quantity (EOO) = 894 units
Now suppose that the management is considering switching to a fixed time inventory system where the time between orders is 2 weeks. Everything else being the same as the information provided for the original problem, which system (Q or P system) is likely to have more safety stock? Please explain why.
Sam's Pet Hotel operates
52
weeks per year,
6
days per week, and uses a continuous review inventory system. It purchases kitty litter for
$13.00
per bag. The following information is available about these bags:
≻Demand=75

≻Order

≻Annual

≻Standard

≻Current
on-hand inventory is
320
bags, with no open orders or backorders.
Part 2
a. Suppose that the weekly demand forecast of
75
bags is incorrect and actual demand averages only
50
bags per week. How much higher will total costs be, owing to the distorted EOQ caused by this forecast error?
The costs will be

A store has collected the following information on one of its products:Demand = 4,500 units/year Standard deviation of weekly demand = 12 units Ordering costs = $40/order Holding costs = $3/unit/year Cycle-service level = 90% (z for 90% = 1.28) Lead-time = 2 weeks Number of weeks per year = 52 weeks a.
If a firm uses the continuous review system to control the inventory, what would be the order quantity and reorder point?
