If you will be an operations manager of Zitcongs taxi business in Bangkok, solve the problem of Zitcong by assigning the taxis to the clientele (1:1). Because of customers preference regarding the driver, taxi 1 cannot be assigned to customer D, and taxi 6 cannot be assigned to customer K or L. Solve this problem using the Solver function of MS Excel. Find the optimal assignment that could achieve the minimum total mileage. This is an imbalance assignment model, hence there are two customers who will not get an assigned taxi. Paste a screenshot of your spreadsheet solution in # 3 of course paper.
