Research On Public Bicycle Vehicle Allocation Problem In Taiyuan

Environmental problems continue to increase,the greenhouse effect,atmospheric warming,increasing haze weather,we realized that the necessity of green travel.Governments at all levels to actively respond to national call to supervise the public to use simple travel,less damage to the low carbon traffic daily travel to the environment,have launched zero pollution,zero emissions,green health,city public bicycle rental service system convenient.Taiyuan is no exception,four seasons climate,as the most suitable cycling city,in the second half of 2012,led by government,built a public bicycle system within the city,convenient for people to travel to bring.The quality and leasing point of the system layout are inseparable,more closely related to the vehicle scheduling of bicycle.However,there are often people in the peak period,"to borrow the car rental points,no pile can also occur situation.So the research on the scheduling problem of bicycle is of practical significance.This paper expounds the embodiment of public bicycle development and social background at home and abroad,studied the relevant theoretical system,and based on the analysis of the function and location of the Taiyuan public bicycle in the city public transportation system in Taiyuan City,combined with the specific conditions,analysis of the day which is the peak time of peace the peak of public bicycle travel,and to determine the number and frequency of public bike is needed.Finally,a numerical example analysis,establish the model,with the greatest satisfaction peak in public as the goal,the establishment of a vehicle scheduling problem with time window path and the peak period to minimize cost as the goal,establish a time window cost optimal path optimization,so the establishment of specific model of two vehicle allocation.Programming with MATLAB simulation,the optimal path.Finally,based on this research subject,put forward opinions and suggestions.
