3 .Results of Model
In this chapter the results of the basic model will be described and discussed，Additionally a sensitivity analysis will be done in order to estimate the delays under different conditions of capacity and demand at Logan.
3.1 Description of Results of Model
We have run the model described in Chapter 2 and derived statistics on the delays to landing operations at Logan for 250 days. For each day of analysis, the following statistics were Collected: total capacity, total demand, total delay, maximum delay per aircraft, number of delays greater than 15 minutes, the average hourly delay for each hour, and the average delay per aircraft. A brief explanation of these statistics is in order. Total capacity for each day is the total capacity generated by the weather model for each day and is a stochastic quantity. Total demand for each day is derived from the demand profile, and is thus non-stochastic. The total delay for each day is the sum of the delays for each aircraft landing that day. The maximum daily delay is the maximum of the delays


在這一個(gè)章節(jié)中，我們將描述和討論基本模型的結(jié)果，另外我們將以洛根（Logen）機(jī)場(chǎng)為依據(jù)做一個(gè)有意義的分析：估算不同狀況下的延遲的能力。
3.1 模型結(jié)果的描述
我們已經(jīng)在第二章的洛根機(jī)場(chǎng)的延遲模型描述和整理后統(tǒng)計(jì)數(shù)字中忙了250天之久了，在每天的分析中, 我們收集了下面的統(tǒng)計(jì)數(shù)據(jù): 總?cè)萘?、要求容量、總延遲、每一飛機(jī)最大值延遲、 延遲大于 15 分鐘、 每小時(shí)的平均每小時(shí)延遲 、和每架飛機(jī)平均延遲。并對(duì)這些統(tǒng)計(jì)數(shù)據(jù)作出了簡(jiǎn)短的解釋。每天的總?cè)萘渴怯擅刻斓奶鞖饽Ｐ秃鸵粋€(gè)隨機(jī)數(shù)產(chǎn)生的。每天的要求容量是客觀需求的，因此不是隨機(jī)的。每天的總延遲是那天登陸的每架飛機(jī)的延遲的總數(shù)。每日最大延遲是那天的飛機(jī)登陸經(jīng)歷的延遲的最大值。 平均的每日延遲是在一個(gè)給定的日子期間所有的飛機(jī)登陸經(jīng)歷的延遲的平均。 一個(gè)給定時(shí)刻的平均每小時(shí)的延遲是進(jìn)入等待的隊(duì)伍在那小時(shí)期間登陸的每架飛機(jī)遇到的延遲的平均。 (并非在那小時(shí)內(nèi)登陸的飛機(jī)遇到的平均的延遲)
通過(guò)前面250天的分析，每時(shí)期的總延遲、最大延遲、和平均延遲是每架飛機(jī)所有延遲的平均。
除非另外說(shuō)明，所以的統(tǒng)計(jì)將以分鐘計(jì)。每天開始和結(jié)束于早上五點(diǎn)。所以的統(tǒng)計(jì)都將以實(shí)際的數(shù)據(jù)為依據(jù)。
3、2 模型結(jié)果
我們首先來(lái)看在第二章中所描述的基本模型，在這個(gè)基本模型中所用
