detailed description

The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

Fig. 1 shows a schematic flowchart of a method for setting the number of bus seats provided by an embodiment of the present invention. As shown in FIG. 1 , the method for setting the number of bus seats in this embodiment includes steps S11 to S13.

S11. Obtain the number of passengers on the bus and the number of people with seats at different times within a preset time period.

In this embodiment, the preset time period is defined according to the needs of the observer and statistician, and may be one day, one month or other time periods.

S21. Determine passenger satisfaction within the preset time period according to the number of passengers, the number of people with seats and a preset passenger satisfaction model.

Passenger satisfaction with the bus depends largely on the number of passengers on the bus and whether there are enough seats on the bus for passengers. If passengers often do not have seats, or even sometimes there are too many people on the bus, the satisfaction of passengers will be reduced, so a passenger satisfaction model is established.

S13. Determine the number of seats that should be added on the bus according to the satisfaction of the passengers within the preset time period.

The method for setting the number of bus seats in this embodiment determines the number of seats on the bus by counting the passenger satisfaction on the bus, improves the comfort of the passengers on the bus, and satisfies the passenger's desire for the bus to the greatest extent. ride needs.

In a preferred embodiment of the present invention, step S12 specifically includes sub-steps S121 and S122 not shown in FIG. 1 .

S121. According to the number of passengers and the number of people with seats, determine the proportion of the number of people without seats at different times.

S122. Determine passenger satisfaction within the preset time period according to the ratio of the number of people without seats at different times and a preset passenger satisfaction model.

Sub-step S121 specifically determines the proportion of the number of people without seats at different times through the following formula:

${\mathrm{<span\; class="notranslate">\; R</span>}}_{\mathrm{<span\; class="notranslate">\; k</span>}}<span\; class="notranslate">\; =</span>\frac{\mathrm{<span\; class="notranslate">\; L</span>}<span\; class="notranslate">\; -</span>\mathrm{<span\; class="notranslate">\; 1</span>}}{\mathrm{<span\; class="notranslate">\; L</span>}}<span\; class="notranslate">\; ;</span>$

Wherein, R _k is the proportion of the number of people without seats at different times, k represents different times in the preset time period, k∈[1, N], N is a preset constant, L is the number of passengers, l for the number of people with seats.

Sub-step S122 specifically determines passenger satisfaction within the preset time period through the following formula:

$\mathrm{<span\; class="notranslate">\; R</span>}<span\; class="notranslate">\; =</span>\frac{\mathrm{<span\; class="notranslate">\; 1</span>}}{\mathrm{<span\; class="notranslate">\; N</span>}}\underset{\mathrm{<span\; class="notranslate">\; k</span>}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; 1</span>}}{\overset{\mathrm{<span\; class="notranslate">\; N</span>}}{<span\; class="notranslate">\; \&Sigma;</span>}}{\mathrm{<span\; class="notranslate">\; R</span>}}_{\mathrm{<span\; class="notranslate">\; k</span>}}<span\; class="notranslate">\; ;</span>$

Wherein, R is the passenger's satisfaction within the preset time period.

In this embodiment, a Monte Carlo algorithm is used to simulate passenger satisfaction R within the preset time period. Monte Carlo algorithm is a general term for a class of stochastic methods. The characteristic of this type of method is that approximate results can be calculated on random sampling. With the increase of sampling, the probability of the correct result gradually increases, but before the real result is obtained, it is impossible to know what the current result is Not really the result.

The Monte Carlo algorithm has strong adaptability, and the complexity of the problem has little effect on it. The convergence of the algorithm refers to the convergence in the sense of probability, so the increase of the dimension of the problem will not affect its convergence speed, and the storage unit is also saved.

The method for setting the number of bus seats in this embodiment uses the Monte Carlo algorithm to calculate the proportion of the number of people who do not have seats in each time period. car satisfaction.

In a preferred embodiment of the present invention, step S13 specifically determines the number of seats that should be added on the bus by the following formula:

$\mathrm{<span\; class="notranslate">\; m</span>}<span\; class="notranslate">\; =</span>\frac{\mathrm{<span\; class="notranslate">\; no</span>}\mathrm{<span\; class="notranslate">\; R</span>}}{\mathrm{<span\; class="notranslate">\; 1</span>}<span\; class="notranslate">\; -</span>\mathrm{<span\; class="notranslate">\; R</span>}}<span\; class="notranslate">\; ;</span>$

Among them, m is the number of seats that should be added on the bus, n is the current number of seats on the bus, and R is the satisfaction degree of passengers within the preset time period.

Because the time zone where the passengers take the bus is different from the destination, it is random. In order to ensure the accuracy of the data, the randomness is not affected. Its ride time is calculated from six o'clock in the morning to nine o'clock in the evening, and is calculated on an hourly basis. Thus, the distribution of the number of passengers per hour is obtained. In addition, it is necessary to count the number of passengers every day within a week, so as to obtain the distribution of the number of passengers per hour of each day.

Make the passenger's satisfaction within the preset time period equal to the proportion of passengers without seats, so the passenger's satisfaction can be calculated when the current number of seats is n. According to n and R, the number of additional seats can be calculated. The calculation formula is:

$\mathrm{<span\; class="notranslate">\; R</span>}<span\; class="notranslate">\; =</span>\frac{\mathrm{<span\; class="notranslate">\; m</span>}}{\mathrm{<span\; class="notranslate">\; m</span>}<span\; class="notranslate">\; +</span>\mathrm{<span\; class="notranslate">\; no</span>}}<span\; class="notranslate">\; ;</span>$

Among them, m is the number of seats that should be added on the bus, n is the current number of seats on the bus, and R is the satisfaction of passengers within the preset time period.

After derivation and conversion, we can get:

$\mathrm{<span\; class="notranslate">\; m</span>}<span\; class="notranslate">\; =</span>\frac{\mathrm{<span\; class="notranslate">\; no</span>}\mathrm{<span\; class="notranslate">\; R</span>}}{\mathrm{<span\; class="notranslate">\; 1</span>}<span\; class="notranslate">\; -</span>\mathrm{<span\; class="notranslate">\; R</span>}}<span\; class="notranslate">\; .</span>$

The method for setting the number of bus seats in this embodiment can quickly calculate the number of seats that should be added to the bus, providing a scientific basis for the improvement of the bus.
