公交車調(diào)度方案設(shè)計
公交車調(diào)度優(yōu)化模型設(shè)計
摘要 本文所要解決的是公交車調(diào)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(diào)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(shè)定1系列的指標(biāo)，利用模糊評價的方法來對調(diào)度方案進行綜合分析與評價。其次，把這個調(diào)度問題抽象成為1個數(shù)學(xué)規(guī)劃模型，通過到本城市公交車站實地調(diào)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(jié)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(dá)雙方最優(yōu)滿意度（0.8807，0.8807），且此時結(jié)果為474次50輛；從日共需車輛最少考慮，結(jié)果為484次45輛。對問題2，交待了綜合效益目標(biāo)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(guān)鍵詞 公交調(diào)度；層次分析；滿意度。
Abstract This text wants to resolve of is data data and requests that bus adjust a degree problems, have according to first, in consideration of horary restrict in car in etc. in passenger, established a line model, make begged of adjust a project even meet the topic request.Then, hand over with from the passenger the benefits of the company set out, setting up a series of index sign, making use of the method of the misty evaluation to make exchange a project proceed to synthesize the analysis and evaluate.The next in order, adjust an of thises degree the problem abstraction becomes a the piece learns to program the model, passing this city bus stop on-site inspection visit, being carried the camp data collects the method.Finally, made use of the method that calculator imitate to proceed the examination to the model, at the same time to the merit and shortcoming proceeding of the model analysis, and put forward to improve the direction.In model first, to problem 1 established to beg the biggest a capacity, car the number of times, hair car time partition etc. model, application decision the method gave the biggest a capacity in each time counts, comparing with biggest a capacity in vehicle again, getting a minimal car for carrying overly should hour a passenger a minimal vehicle for 462 times, from the easy to operation with hair car density considering, giving first wholely distributing the car schedule with needing count 61.Model two establish the misty analysis model, the combination level of structure analysis begs the model on bringing the company with both parties day in passenger approval is;(0.941,0.811)According to both parties approval scope with degree, find out to arrive the both parties superior approval(0.8807,0.8807) at the same time, and the this time result is 474 times 50;Need the vehicle totally from the day minimal consider, result is 484 times 45.To the problem 2, handed over to treat to synthesize performance target model and line programming methods beg the solution.For the problem 3, asked for help to check the data with collects data.
Keywords The hands 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(diào)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(jīng)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(diào)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(diào)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(biāo)準(zhǔn)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(diào)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(yīng)超過120%，1般也不要低于50%。
試根據(jù)這些資料和要求，為該線路設(shè)計1個便于操作的全天(工作日)的公交車調(diào)度方案，包括兩個起點站的發(fā)車時刻表；1共需要多少輛車；這個方案以怎樣的程度照顧到了乘客和公交公司雙方的利益等等。
如何將這個調(diào)度問題抽象成1個明確、完整的數(shù)學(xué)模型，指出求解模型的方法；根據(jù)實際問題的要求，如果要設(shè)計更好的調(diào)度方案，應(yīng)如何采集運營數(shù)據(jù)。
