公交車調度方案設計

1、公交車調度方案設計 公交車調度優(yōu)化模型設計  摘要  本文所要解決的是公交車調度的問題，首先根據(jù)所具備的數(shù)據(jù)資料以及要求，考慮到乘客等車時間的限制，建立了1個線性模型，使所求得的調度方案更符合題目要求。然后，從乘客與公交公司的利益出發(fā)，設定1系列的指標，利用模糊評價的方法來對調度方案進行綜合分析與評價。其次，把這個調度問題抽象成為1個數(shù)學規(guī)劃模型，通過到本城市公交車站實地調查訪問，得到運營數(shù)據(jù)的采集方法。最后，利用計算機模擬的方法對模型進行了檢驗，同時對模型的優(yōu)缺點進行了分析，并提出改進方向。在模型1中，對問題1建立了求最大客容量、車次數(shù)、發(fā)車時間間隔等模型，運用

2、決策方法給出了各時段最大客容量數(shù)，再與車輛最大客容量比較，得出載完該時組乘客的最少車次462次，從便于操作和發(fā)車密度考慮，給出了整分發(fā)車時刻表和需要的最少車輛數(shù)61輛。模型2建立模糊分析模型，結合層次分析求得模型1帶給公司和乘客雙方日滿意度為（0.941，0.811）；根據(jù)雙方滿意度范圍和程度，找出同時到達雙方最優(yōu)滿意度（0.8807，0.8807），且此時結果為474次50輛；從日共需車輛最少考慮，結果為484次45輛。對問題2，交待了綜合效益目標模型及線性規(guī)劃法求解。對于問題3，借助了查閱資料和搜集數(shù)據(jù)。關鍵詞  公交調度；層次分析；滿意度。abstract this text

10、 over to adjust degree; level of structure analysis;approval.1 前言公共交通是城市交通的重要組成部分。做好公交車的調度，對于完善城市交通環(huán)境、改進市民出行狀況、提高公交公司的經濟和社會效益，都具有重要意義。下面考慮1條公交線路上公交車的調度問題，其數(shù)據(jù)來自我國1座特大城市某條公交線路的客流調查和運營資料。該條公交線路上行方向共14個站，下行方向共13站，表1.1和表1.2給出的是典型的1個工作日兩個運行方向各站上下車的乘客數(shù)量統(tǒng)計。公交公司配給該線路同1型號的大客車，每輛標準載客100人，據(jù)統(tǒng)計客車在該線路上運行的平均速度為20公里每小時。運營調度要求，乘客候車時間1般不要超過10分鐘，早高峰時1般不要超過5分鐘，車輛滿載率不應超過120%，1般也不要低于50%
