By reasonably calculating supply volume, cost objective function minimum is solved, economic cost can be more preferably saved, reduces and solves to share
Bicycle parks the economic input of problem, and the commercialization for being conducive to parking device is promoted.3, full by reasonably calculating supply volume
Sufficient active user is to sharing the use demand amount of bicycle, under conditions of taking into account the flexible convenient feature of shared bicycle, rationally
Control stops pick-up, is conducive to shared traffic long-term sustainable development.
Description of the drawings
Fig. 1 is the calculation process of the shared bicycle parking device dispensing method for measuring and calculating shown according to an exemplary embodiment
Figure.
Fig. 2 is to solve bicycle parking device in the dispensing number for planning point according to the graphical method shown in an exemplary embodiment
Amount.
Specific implementation mode
The disclosure is described in further detail with reference to the accompanying drawings and detailed description.
The disclosure draws the parking stall of a certain range area as spare parking stall by bicycle parking device.Bicycle parks dress
The prior art can be used in the structure set.
As shown in Figure 1, a kind of shared bicycle parking device launches method for measuring and calculating, include the following steps：
Step 1：The shared bicycle of statistical rules point parks demand Ni, wherein bicycle parks demand NiIt should be greater than parking
The capacity M of device, if parking demand NiLess than the capacity M of parking device, then can in the places such as residential quarters, campus basis
A parking device is set up in the distribution of building facilities so that the construction cost of Trip Costs and shared bicycle Parking Facilities is minimum.
Step 2：Construction bicycle parks demand NiDistribution law pk, wherein pkDemand is parked to there is k shared bicycle
Probability, i.e., each discrete random variable NiThe number that=k occurs accounts for the Probability p of sample totalk, pk>=0, k are positive integer,Such as k=1, the planning of certain moment, which is put, only has 1 vehicle to park, at this time pkFor in timing statistics section, which only has
The probability that 1 shared bicycle is parked.It can specifically be investigated by the following method：Select a shared intensive diamond of bicycle
Quantity is parked in domain, it is specified that recording once shared bicycle per hour, is denoted as a sample size, can then obtain 24 sample sizes within one day,
Sample total number is 24.
Step 3：The bicycle parking device injected volume measuring and calculating integer programming model is established, which is
Object function.In addition, the model needs to consider following restraint condition：
1) berth that parking device can provide can meet the demand of parking of 100 α % (0≤α≤1), parking device side
Then demand is parked for meeting remaining 100 (1- α) % in the spare parking stall for applying picture.Calculate when a can value 0.95, that is, stop
95% can be met and park demand by putting the berth of device offer.
2) floor space on the spare parking stall of parking device and parking device side should be less than planning point for bicycle parking
Area S.
3) floor space on spare parking stall should be less than the floor space of single parking device.
4) Berth number that parking device is provided with spare parking stall can meet the needs of maximum parking capacity Nmax.
Therefore, combined objective function and constraints establish following mathematical model：
Min=aimx1+ainx2+bix1+cix1；
In formula：Min is cost of investment；aiFor the land used value coefficient of planning point, that is, the price for the land user's area that stops
Coefficient, with reference in " China Wang Yue Land resources classification method compares and value accounting research [D] Maritime Affairs University Of Dalian .2008 "
Public facilities value belong to transiens land used value, be equal to land price；biPrimary construction cost system is launched for parking device
Number can be the cost and the sum of freight and assembly expenses of single parking device；ciFor the operation maintenance of parking device later stage
Cost coefficient can be annual maintenance cost；x1For parking device supply volume；x2To be located at spare parking by parking device
Bits number；M is single parking device floor space；N is the floor space on single spare parking stall；D is the number of plies of parking device.
Step 4：Calculate integer programming model according to injected volume and calculates bicycle parking device in the supply volume x for planning point1。
Specifically, graphical method solution may be used, first acquire optimal solution in feasible zone, it is whole according to optimal solution progress.But if there is n
A decision variable, then accepting or rejecting scheme has 2nKind.Decision variable is 2 in embodiment, so at most in 4 kinds of schemes relatively
The optimal solution asked.As shown in Fig. 2, the x of cost of investment function min1Coefficient is more than x2Coefficient,It enablesMinimum, i.e. intercept are minimum, in figure in feasible zone and axis of ordinates
Bottom have optimal solution, be compared in optimum point attachment round numbers point.
Below using the Wuhan City friendship main road gardens Chai Lin bus stop as planning point, to illustrate the specific measuring and calculating of injected volume
Process.
It shares bicycle and parks application form in the 1 friendship main road gardens Chai Lin bus stop of table
The discrete random variable amount of parking N is calculated according to 1 data of tableiDistribution law, aiLaunch the land used value coefficient in area；
biParking cabinet launches primary construction cost coefficient；ciParking cabinet later stage operation maintenance cost coefficient, wherein in view of bus stop is
Road and means of transportation land used, there is bi>ci>aiRelationship.A can not be known in example calculationi、bi、ciThe same energy of concrete numerical value
It solves, due to cost necessarily x1With x2Value it is smaller, cost is smaller, so being taken under conditions of meeting inequality in example
X1And x2Smallest positive integral solution.Assuming that one 3 layers of parking device capacity M is 24, floor space m is 9 square metres, it is single standby
It it is 0.8 square metre with the floor space n on parking stall, actual measurement S is 40 square metres for the area of bicycle parking, Nmax statistics
It is 99 that shared bicycle, which parks demand peak value,.
Min=9aix1+0.8aix2+bix1+cix1；
The x of solution1=4, x2=3
It needs to put 4 parking cabinets in the friendship main road gardens Chai Lin bus stop, while setting-out planning 3 is reserved on periphery
A parking stall.
It only lists three days data in table 1 to demonstrate as process, practical application need to be calculated in conjunction with big data sample size
Rational supply volume.
The phenomenon that planning point bicycle demand of parking should not consider manually to allocate and transport in the embodiment of the present disclosure, takes a long view, is
Using balance as a result, being finally reached the degree of supply-demand structure in region.
