Case Study A Bicycle Company is a whole-sale distributor of bicycles and bicycle parts. The firm's primary retail outlets are located within a 650-kilometre radius of the distribution centre. These retail out- lets receive the order from this bicycle company within two days after notifying the distribution centre, provided that the stock is available. However, if an order is not fulfilled by the company, no backorder is placed; the retailers arrange to get their shipment from other distributors, and the bicycle company loses that amount of business. The company distributes a wide variety of bicycles. The most popular model, and the major source of revenue to the company, is the Air Wing The bicycle company receives all the models from a single manufacturer in another country, and shipment takes as long as four weeks from the time an order is placed. With the cost of communication, paperwork, and customs clearance included, the bicycle company estimates that each time an order is placed, it incurs a cost of $65. The purchase price paid by the bicycle company, per bicycle, is roughly 60% of the suggested retail price for all the styles available, and the inventory carrying cost is 1% per month (12% per year) of the purchase price paid by the bicycle company. The retail price (paid by the customers) for the AirWing is $170 per bicycle. The bicycle company is interested in making an inventory plan for 2019. The firm wants to maintain a 95% service level with its customers to minimize the losses on the lost orders. The data collected for the past two years are summarized in the preceding table. A forecast for AirWing model sales in 2019 has been developed and will be used to make an inventory plan for the bicycle company. 2018 7 Forecast for 2019 8 15 14 27 53 86 Demands for AirWing Model Month 2017 January 6 February 12 March 24 April 46 May 75 June 47 July 30 August 18 September 13 October 12 November 22 December 38 Total 343 31 59 97 60 54 34 39 21 24 16 15 13 15 28 25 42 391 47 439 Discussion Questions 1.
