QUESTION 1: Two products (E, F) will be distributed in a system having three dealers (D1, D2, D3). Four candidate central warehouse location sites (CWI, CW2, CW3, CW4) are available. CW2 must be opened before opening CW1. However, opening CW2 does not imply that CW1 will be opened, only that it can be. If CW3 is opened, then CW4 should also be opened, and vice versa. Two central warehouses must be opened in the system. The sales amount of product E at D1, D2 and D3 is estimated as 9300 units, 11.500 units and 8600 units, respectively. On the other hand, product F's sales amount is predicted as 6250 units, 8900 units and 4300 units at D1, D2 and D3, respectively. Other related data are provided below. The supply costs for both products are the same. Construct the location-allocation model of the system (Define the decision variables explicitly!). Warehouse location Fixed cost (TL) Warehouse capacity (units) CW1 325,000 25,000 CW2 775,000 19.800 CW3 490.000 7600 CW4 605,000 9750 Supply cost (TL/unit) D1 D2 D3 Dosyanz bulmak iin "Gzat" seeneine ve yklemek iin "Ykle" seeneine tklayn.

(10 points) The depot manager has decided to locate a parking area for the forklifts anywhere in the depot. Assuming rectilinear distance, where must this new parking area be located? b. (15 points) Now suppose that the parking area will be located outside the depot, and either along the west or the south wall. Which side of the depot is more appropriate?
