The XYZ Company has six retail sales stores in the city of San Marcos. The company needs a new warehouse facility to service its retail stores. The location of the stores and the expected number of deliveries per week from the warehouse to each store are Store Location (miles Expected Deliveries 4 (2, 5) (3, 8) 4 6 Assume that the travel distance within the city of San Marcos is rectilinear and that after eaclh delivery the delivery truck must return to the warehouse. If there are no restrictions on the warehouse location, estimate where it should be located using the Mini-Sum method Single-Facility Mini-Sum Location Problem FORMULA · X=(x, y) · P=(a, b) location of the new facility location of existing facility = 1, 2, 3, n "weight" associated with travel between the 戡 new facility and existing facility i The objective is to Minimize f(X) = Sum! WL d(X, Pi) where d(X, Pi,-/-al/ + /y-bl/ Minimize f(X) = Sum Mi /r-al/ Sum Wi + bl/ .
