Delays at Logan Airport 1. A) Delay in minutes per plane: Λ = 50 | Λ = 55 | Λ = 59 | 6.54 minutes | 12.52 minutes | 60.5 minutes |

Delay costs:
Turboprop:
Λ = 50 6.54min*($352 + 65%load*15passengers*$30.9)/60 = $71.20
Λ = 55 12.52min*($352 + 65%load*15passengers*$30.9)/60 = $136.31
Λ = 59 60.5min*($352 + 65%load*15passengers*$30.9)/60 = $658.72
Regional jet:
Λ = 50 6.54min*($672 + 65%*50passengers*$30.9)/60 = $182.71
Λ = 55 12.52min*($672 + 65%*50passengers*$30.9)/60 = $349.78
Λ = 59 60.5min*(672 + 65%*50passengers*$30.9)/60 = $1690.22
Conventional jet:
Λ = 50 6.54min*($1590 + 65%*150passengers*$30.9)/60 = $501.70

As shown by the case, when the arrival rate exceeds the service rate, costs will be incurred for the airport in terms of both passenger and operational costs as a result of delays. A second assumption of queuing theory is that there is only one waiting line, even when there are multiple channels. However, in the case, there are multiple channels (various runways), but there are separate waiting lines for arrivals for each runway. B) Peak time is between the hours of 5 and 6 pm.
Arrival rate between 5 and 6 pm is between 55-60 planes/hour
Good weather:
-Two runways for only arrivals (three used total).
-Arrival capacity = 30 planes/runway/hour delay time ranges from 12.52-60.5 min/plane. Delay costs for the different types of planes during good weather has been calculated in part 1.A.
Adverse weather:
i) Bad weather
-Two runways used for both arrivals and departures.
-Arrival capacity = 22.5 planes/runway/hour delay time cannot be calculated because the arrival rate exceeds the arrival capacity. ii) Severe weather
-One runway used for both arrivals and departures.
-Arrival capacity = 30 planes/runway/hour delay time cannot be calculated because the arrival rate exceeds the arrival capacity.

4. We believe that in the short run, peak-period pricing would be an effective measure to manage demand and reduce delays. Looking at our calculations from question one, when the arrival rate increases by merely five more planes/hour, much
