機(jī)場航空管制模擬實(shí)驗(yàn)報(bào)告

機(jī)場航空管制模擬實(shí)驗(yàn)報(bào)告實(shí)驗(yàn)題目假設(shè)機(jī)場有一條跑道，每架飛機(jī)需花費(fèi)一定時(shí)間著陸，花費(fèi)一定時(shí)間起飛，飛機(jī)的起降滿足一定的概率。一般來講，機(jī)場存在兩個(gè)隊(duì)列，一個(gè)等待著陸的飛機(jī)隊(duì)列和一個(gè)等待起飛的飛機(jī)隊(duì)列，同樣等待時(shí)間下，等待著陸的飛機(jī)比準(zhǔn)備起飛的飛機(jī)具有更高的優(yōu)先級。試編寫程序模擬這個(gè)機(jī)場的運(yùn)行。要求使用隊(duì)列或優(yōu)先隊(duì)列實(shí)現(xiàn)；要求可以變換起飛和著陸頻率來模擬一天中的飛行頂峰期和空閑期；要求可以改變著陸和起飛時(shí)間以模擬不同的效果。實(shí)驗(yàn)內(nèi)容分析1.1實(shí)驗(yàn)?zāi)康膶?shí)驗(yàn)?zāi)M了機(jī)場的航空管制，通過程序，來模擬管理飛機(jī)的起飛與著陸。它要求我們考慮起飛與著陸的優(yōu)先級不同，以及根據(jù)飛機(jī)起飛/著陸時(shí)間，起飛/著陸頻率模擬機(jī)場一天的運(yùn)營情況。并計(jì)算出跑道的繁忙程度、著陸飛機(jī)的總的等待時(shí)間和平均等待時(shí)間、起飛飛機(jī)的總的等待時(shí)間和平均等待時(shí)間,計(jì)算每架飛機(jī)花費(fèi)在一個(gè)隊(duì)列中的平均時(shí)間。1.2內(nèi)容分析 系統(tǒng)主要模擬了機(jī)場一天的運(yùn)營。所以，需要一個(gè)計(jì)時(shí)器〔以分鐘計(jì)時(shí)〕來計(jì)算機(jī)場的運(yùn)營時(shí)間。同時(shí)，為了管理飛機(jī)的起飛與著陸，需要兩個(gè)隊(duì)列來存放著陸和起飛的飛機(jī)。 設(shè)計(jì)用戶輸入的數(shù)據(jù)為：機(jī)場開始、結(jié)束運(yùn)營時(shí)間；頂峰期開始、結(jié)束時(shí)間；空閑期開始、結(jié)束時(shí)間；著陸飛機(jī)最長等待時(shí)間；頂峰期、空閑期以及一般時(shí)期每小時(shí)起飛、著陸的飛機(jī)數(shù)，飛機(jī)起飛、著陸需要的時(shí)間?？紤]到機(jī)場的頂峰期，與空閑期，設(shè)計(jì)了Workslot類，設(shè)定不同時(shí)期的飛機(jī)起飛、著陸率。設(shè)計(jì)Timer類，其主要方法是實(shí)現(xiàn)計(jì)時(shí)功能和返回當(dāng)前工作時(shí)間。Plane類主要功能是記錄飛機(jī)開始等待時(shí)間，開始工作時(shí)間以及起飛、著陸所需時(shí)間。飛機(jī)起飛/著陸都需要花費(fèi)一定的時(shí)間，并不是馬上就完成的。所以在起飛/著陸效勞函數(shù)中，不僅要調(diào)用spend〔〕，還需要判斷takeoff/landing是否結(jié)束。當(dāng)t.now-startworktime<workTime時(shí)，說明飛機(jī)還在準(zhǔn)備著陸/起飛，占用了跑道。當(dāng)t.now-startworktime==workTime時(shí)，表示飛機(jī)著陸/起飛成功。調(diào)用pop方法，從隊(duì)列中刪除一架等待效勞的飛機(jī)，并獲取當(dāng)前時(shí)間，減去飛機(jī)接受效勞的時(shí)間，得到該飛機(jī)的等待效勞時(shí)間。我們就可以計(jì)算出所有飛機(jī)的等待效勞時(shí)間。等待起飛/著陸隊(duì)列總長度，等待效勞總時(shí)間，以及效勞起飛/著陸的飛機(jī)總數(shù)，我們就可以得出起飛/著陸飛機(jī)的平均等待時(shí)間，平均等待隊(duì)列長度。同時(shí)根據(jù)當(dāng)天的的工作時(shí)間，跑道的忙碌時(shí)間，可以計(jì)算得到跑道的繁忙程度。1.3程序根本流程圖1實(shí)驗(yàn)根本流程1.4根本數(shù)據(jù)結(jié)構(gòu)，類設(shè)計(jì)1.4.1類Airport輸入:變量名注釋Timert;計(jì)時(shí)器StructBusyb;跑道是否忙碌inttakeoffTime;飛機(jī)起飛所需時(shí)間intlandingTime;飛機(jī)著陸所需時(shí)間intstartworkTime;機(jī)場當(dāng)天開始運(yùn)營時(shí)間intendworkTime;機(jī)場當(dāng)天結(jié)束運(yùn)營時(shí)間ClassWorkslothighslot;頂峰時(shí)間段ClassWorkslotlowslot;空閑時(shí)間段ClassWorkslototherslot;一般時(shí)間段deque<Plane>takeoffq;等待起飛飛機(jī)隊(duì)列deque<Plane>landingq;等待著陸飛機(jī)隊(duì)列intworkTime;跑道忙碌時(shí)間intTwaitTime;總起飛等待時(shí)間intLwaitTime;總著陸等待時(shí)間inttakeoffwaitTime;所有起飛飛機(jī)總等待時(shí)間intlandingwaitTime;所有著陸飛機(jī)總等待時(shí)間intmaxlandingwaitTime;最大著陸等待時(shí)間intintakeoffNum;進(jìn)入起飛隊(duì)列飛機(jī)數(shù)intinlandingNum;進(jìn)入著陸隊(duì)列飛機(jī)數(shù)inttakeoffNum;已經(jīng)起飛飛機(jī)數(shù)intlandingNum;已經(jīng)著陸飛機(jī)數(shù)intt_rate;用來保存起飛速率intl_rate;用來保存著陸速率輸出變量名備注t.now當(dāng)前時(shí)間inttakeoffNum當(dāng)前已起飛飛機(jī)數(shù)量intlandingNum當(dāng)前已著陸飛機(jī)數(shù)量intintakeoffNum當(dāng)前已入起飛隊(duì)列飛機(jī)數(shù)intinlandingNum當(dāng)前已入著陸隊(duì)列飛機(jī)數(shù)deque<Plane>takeoffq起飛隊(duì)列，元素類型為飛機(jī)類型deque<Plane>landingq著陸隊(duì)列，元素類型為飛機(jī)類型double(workTime/(endworkTime-startworkTime))跑道的繁忙程度〔用機(jī)場總工作時(shí)間與跑道忙碌時(shí)間之比來衡量〕doublelandingwaitTime著陸飛機(jī)總的等待時(shí)間double(landingwaitTime/landingNum)著陸飛機(jī)平均等待時(shí)間double(LwaitTime/landingNum)著陸飛機(jī)在隊(duì)列中的平均等待時(shí)間doubletakeoffwaitTime起飛飛機(jī)總的等待時(shí)間double(takeoffwaitTime/takeoffNum)起飛飛機(jī)平均等待時(shí)間double(TwaitTime/takeoffNum)起飛飛機(jī)在隊(duì)列中的平均等待時(shí)間intIntakeoffNum–takeoffNum運(yùn)營結(jié)束時(shí)，起飛隊(duì)列中剩余飛機(jī)數(shù)量成員方法名備注voidrun()運(yùn)行仿真voidsetTimer()設(shè)定計(jì)時(shí)器函數(shù)voidsetTakeoffTime(intt1)設(shè)定起飛所需時(shí)間函數(shù)voidsetLandingTime(intt2)設(shè)定著陸所需時(shí)間函數(shù)voidsetMaxlandingwaitTime(intmlwd)設(shè)定著陸飛機(jī)最大等待時(shí)間voidsetStartworkTime(strings)設(shè)定機(jī)場開始工作時(shí)間函數(shù)voidsetEndworkTime(strings)設(shè)定機(jī)場結(jié)束工作時(shí)間函數(shù)voidsetHighslot(Worksloth)設(shè)定頂峰期機(jī)場屬性voidsetLowslot(Workslotl)設(shè)定空閑期機(jī)場屬性voidsetOtherslot(Worksloto)設(shè)定一般時(shí)段機(jī)場屬性1.4.2類Plane成員：方法名備注intstartwaitTime開始等待時(shí)間intstartworkTime開始起飛/著陸時(shí)間intworkTime起飛/著陸時(shí)間1.4.3類Timer成員：方法名備注intnow計(jì)時(shí)器當(dāng)前時(shí)間voidspend()計(jì)時(shí)累加函數(shù)1.4.4類Workslot成員：變量名備注intstartTime該時(shí)間段開始時(shí)間intendTime該時(shí)間段結(jié)束時(shí)間inttakeoffRate起飛頻率〔每小時(shí)起飛數(shù)〕intlandingRate著陸頻率〔每小時(shí)著陸數(shù)〕1.4.5結(jié)構(gòu)Busy成員：變量名備注boolis_takeoff跑道中是否為起飛飛機(jī)boolbusy跑道是否忙碌1.5根本函數(shù)功能1.5.1類SimulationsetTimer():設(shè)定計(jì)時(shí)器函數(shù)setTakeoffTime(intt1):設(shè)定起飛所需時(shí)間函數(shù)setLandingTime(intt2):設(shè)定著陸所需時(shí)間函數(shù)setMaxlandingwaitTime(intmlwd):設(shè)定著陸飛機(jī)最大等待時(shí)間setStartworkTime(strings):設(shè)定機(jī)場開始工作時(shí)間函數(shù)setEndworkTime(strings):設(shè)定機(jī)場結(jié)束工作時(shí)間函數(shù)setHighslot(Worksloth):設(shè)定頂峰期機(jī)場屬性setLowslot(Workslotl):設(shè)定空閑期機(jī)場屬性setOtherslot(Worksloto):設(shè)定一般時(shí)段機(jī)場屬性run()：模擬飛機(jī)場運(yùn)營。display()：該函數(shù)主要用于計(jì)算一些值，并輸出在屏幕上。跑道的繁忙程度=

LwaitTime++;這時(shí)就遺漏了當(dāng)隊(duì)列只有一架飛機(jī)但由于跑道此時(shí)為忙碌，所以該飛機(jī)仍處于等待狀態(tài)這種情況，故敬愛那個(gè)代碼修改為：if(takeoffq.size()>1||(takeoffq.size()==1&&takeoffq.front().startworkTime==-1))TwaitTime++;if(landingq.size()>1||(landingq.size()==1&&landingq.front().startworkTime==-1)) LwaitTime++;更改前運(yùn)行結(jié)果：修正后運(yùn)行結(jié)果：3.3.2問題2問題：一開始的程序沒有參加deQueue.h文件，而是直接用了#include<deque>，后面參加程序后一直沒有調(diào)試成功。調(diào)試過程：有報(bào)錯(cuò)框可知，因?yàn)槌绦蜷_始設(shè)定的時(shí)候用了模版類，因此。隊(duì)列類里也需要參加模版函數(shù)。在隊(duì)列類的函數(shù)調(diào)用過程中修改了需要用到的函數(shù)，確保其運(yùn)行成功。解決方法：完善了隊(duì)列類3.3.3問題3問題：要求機(jī)場24:00結(jié)束，但是程序只模擬到21:23分左右，之后再無飛機(jī)產(chǎn)生。而且之后的幾小時(shí)內(nèi)只有起飛飛機(jī)，無著陸飛機(jī)。屢次模擬，均是類似結(jié)果。解決方法：首先分析該問題產(chǎn)生的可能原因，由于這種結(jié)果的太過規(guī)律性，疑心是產(chǎn)生的隨機(jī)數(shù)的問題，因此對產(chǎn)生隨機(jī)數(shù)的語句進(jìn)行分析，發(fā)現(xiàn)是將srand((int)time(0))語句放在for循環(huán)內(nèi)造成的，故將srand((int)time(0))語句放到for循環(huán)外面。測試結(jié)果4.1正常運(yùn)行輸入數(shù)據(jù)正確的情況：輸入數(shù)據(jù)錯(cuò)誤的情況：4.2邊界數(shù)據(jù)測試輸入全部為0后期擴(kuò)展目前程序只模擬了一個(gè)跑道的情況，后期可以使用優(yōu)先隊(duì)列管理跑道，實(shí)現(xiàn)多跑道的飛機(jī)場運(yùn)營模擬。由于實(shí)驗(yàn)要求先處理完著陸隊(duì)列再處理起飛隊(duì)列，可能會(huì)導(dǎo)致模擬出來的情況與實(shí)際不符，期中可能要考慮更多因素，目前的實(shí)現(xiàn)上來說還有待提高。源代碼6.1類設(shè)計(jì)deQueue.h#ifndefDEQUEUE#defineDEQUEUE#include<iostream>usingnamespacestd;template<typenameT>classnode{public:TnodeValue;node<T>*next;node():next(NULL){}node(constT&item,node<T>*nextNode=NULL):nodeValue(item),next(nextNode){}};template<typenameT>classQueue{public:
