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
Λ = 55 12.52min*($1590 + 65%*150passengers*$30.9)/60 = $960.44
Λ = 59 60.5min*($1590 + …show more content…

iii. However, in the potential future scenario of a 10% turboprop, 30% regional jet, and 60% conventional jet mix, the PPP would have an insignificant effect. iv. Our analysis in 1. and 2. shows that the potential savings in delay costs that result from demand management can potentially offset the peak period fees. For example, if the current peak period demand is 59 planes and a fee of $250 can reduce it to 40 planes, the total costs that conventional jets incur decreases from $4641.11 to $526.16. However, if the current demand is 50 planes, a fee of $250, which reduces the demand to 40 planes, would not be offset, Further, it must be noted that conventional jets benefit the most from a decrease in demand resulting from a PPP. If the current demand is 59 planes, for turbotrops the landing fee can be offset from delay costs savings, but this is not the case if the current demand is, for example, 55 or 50 planes. To conclude, the savings in delay costs that result from demand management can offset peak period fees, but only if the initial demand is high and usually only in the case of conventional jets. 3. A) One of the fundamental assumptions of waiting line systems is that the arrival rate cannot exceed the service rate or the system is said to be unstable. In the case, the arrival rate at times is almost equal to, or greater than, the service rate, hence
