Muscle Bound is a chain of fitness stores located in many large shopping centers. Recently, an internal memo from the CEO to all operations personnel complained about the budget overruns at Muscle Bound’s central warehouse. In particular, she said that inventories were too high and that the budget will be cut dramatically and proportionately equal for all items in stock.Consequently, warehouse management set up a pilot study to see what effect the budget cuts would have on customer service. They chose 5-pound barbells, which are a high volume SKU and consume considerable warehouse space. Daily demand for the barbells is 1,000 units, with a standard deviation of 150 units. Ordering costs are $40 per order. Holding costs are $2/unit/year. The supplier is located in the Philippines; consequently, the lead time is 35 days with a standard deviation of 5 days. Muscle Bound stores operate 313 days a year (no Sundays). Suppose that the barbells are allocated a budget of $16,000 for total…
Saché, Incorporated, expects to sell 2,030 of its designer suits every week. The store is open seven days a week and expects to sell the same number of suits every day. The company has an EOQ of 1,450 suits and a safety stock of 290 suits. Once an order is placed, it takes three days for Saché to get the suits in.
How many orders does the company place per year? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.)
Assume that it is Monday morning before the store opens, and a shipment of suits has just arrived. When will Saché place its next order?
