- PART A Speedy Bicycle Company (SBC) is a wholesale distributor of a wide variety of bicycles and bicycle parts. The most popular model is the Dragonfly, which sells for $170. All manufacturing is done at a plant in China, and shipment takes a month (30 days) from the time an order is placed. The estimated order cost is $75, including customs clearance. SBC's cost per bicycle is 65% of retail price, and inventory carrying cost is 11% per year of SBC's cost. If the company cannot fulfill a retail order, the retailer will get the shipment from another distributor and SBC loses that business. SBC is planning inventory for 2023 based on forecasted demand and wants to maintain a 93% service level to minimize lost orders.

Monthly demand for cans of white paint is normal with mean 28 and standard deviation 8. The replenishment lead time is 14 weeks. Excess demand is backordered, but costs $10 per back ordered can in labor and loss of goodwill. There is a fixed cost of $15 per order, and the holding cost is based on 30% interest rate per annum. In your computations, assume 4 weeks per month. - Write down the model name and parameters. - What are the optimal lot size and reorder points for white paint (include the formulas)? - What is the optimal safety stock (include the formula)? *** Suppose the paint shop from the above problem adopts a service level policy. - What are the optimal lot size and reorder points for white paint, such that 90% of the cycles are filled without backordering (include all formulas)? - What is the fill rate…arrow_forward
