An evaluation method of refined oil supply based on space distance and time cost

Abstract

The invention discloses a method for evaluating the supply of refined oil based on space distance and time cost, which comprises the following steps: 1. Drawing and analyzing a map; 2. Adding gas station information; 3. Defining regional divisions; 4. Measuring natural distances; 5. Calculate the effective natural distance; 6. Investigate the queuing situation for refueling; 7. Calculate the proportion coefficient of refined oil supply; 8. Calculate the daily supply of refined oil in regional divisions; 9. Arrange results; The evaluation method of refined oil supply with time cost is helpful for the accurate evaluation of the refined product supply of regional refueling facilities. The evaluation results are more consistent with the actual refueling behavior patterns of users, which is helpful for the rational formulation of refueling facility layout plans.

Description

technical field [0001] The invention relates to the field of urban and rural planning, in particular to a method for evaluating the supply of refined oil based on space distance and time cost. Background technique [0002] Gas stations are supplementary stations that provide refined oil supply for automobiles and other motor vehicles. During the period of rapid growth of motor vehicles in my country, gas stations play a vital role in urban infrastructure. In the traditional urban gas station layout planning method, the service radius is usually used as an important index to measure the service range and radiation range of the gas station. The default refueling facility has zero utility outside its service radius and is not included in the service scope. However, in the actual refueling behavior There are a large number of cases of refueling across the service radius, and the method of using the service radius as the basis for planning also indirectly leads to one-size-fits-a...

Problems solved by technology

In the traditional urban gas station layout planning method, the service radius is usually used as an important index to measure the service range and radiation range of the gas station. The default refueling facility has zero utility outside its service radius and is not included in the service scope. However, in the actual refueling behavior There are a large number of cases of refueling across the service radius, and the method of using the service radius as the basis for planning also indirectly leads to one-size-fits-all rough planning

In addition, because only the service radius is considered, and factors such as refueling mileage, road traffic conditions, refueling idling and queuing time are not included, this method is relatively simple to estimate the actual supply of refined oil at gas stations, and the evaluation results are also consistent with the actual refueling of users. Behavioral patterns do not exactly match, resulting in deviations between layout schemes and demand distribution characteristics
