Problem for Group F (formulate the problem and find optimal solution) Allocation of Aircraft to Routes. Consider the problem of assigning aircraft to four routes according to the following data: 1 2 4 Capacity Aircraft type Number of Number of daily trips on route (passengers) aircraft 3 1 50 5 3 2 30 2 1 3 8 4 3 3 2 20 10 3 5 4 2 Daily number of customers 1000 2000 900 1200 The associated costs, including the penalties for losing customers because of space unavailability, are: Operating cost ($) per trip on route 1 2 3 4 1 1000 1100 1200 1500 2 800 900 1,000 1000 600 800 800 900 Penalty (s) per lost customer 40 50 45 70 Aircraft type Determine the optimum allocation of aircraft to routes, and determine the associated number of trips
