With reference to the management of capacity, briefly explain the concepts of utilisation and efficiency. Assuming that flights to Goa from Mumbai cannot be scheduled to take-off before 0600 hours and return flights cannot land at Mumbai after 2100 hours and that ground staff are able to turn the aircraft around in 25 minutes (rather than the 15-30mins indicated in the case), calculate the improvement in the effective capacity of the aircraft that would be a consequence of a permanent reduction in turnaround time from 25 minutes to 10 minutes, given an average flight time of 50 minutes each way. How would the reduction in turnaround time enable an improved customer service?
