Problems solved by technology

Traditional vehicle scheduling only considers the distance or travel time between two customers, while ignoring the influence of road conditions and different models
This kind of scheduling problem has the following problems: First, the fuel consumption of the car is not only related to the model, but also related to the road conditions on this section of the road, including vehicle speed, acceleration and deceleration, uphill and downhill, etc.
Second, this scheduling model does not take into account the impact of pollutant emissions

Embodiment Construction

[0065] It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other if there is no conflict.

[0066] Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments.

[0067] The invention is intended to be used in a government monitoring vehicle emission system, comprehensively considering the common benefits of the government and the enterprise, taking the minimum fuel consumption, urea consumption and pollutant discharge as the planning goals, and establishing an integer programming model with time windows. Among them, the weight relationship of the three can be determined according to the degree of importance or focus.

[0068]

[0069] The above formula is the objective function. The first part represents the weight multiplied by the standardized value of fuel consumption, the second part represents the weight multiplied by the standardiz...

Abstract

The invention provides a vehicle scheduling and path planning method based on environmental protection and cost saving. Minimization of a fuel oil consumption quantity, a urea consumption quantity anda pollutant emission quantity is used as a planning goal to establish an integer planning model with time windows. According to the method, the fuel oil consumption quantity, the urea consumption quantity and the pollutant emission quantity are used as the goal to design a reasonable vehicle scheduling scheme for an enterprise through data which are input by the enterprise and of the number of and models of distribution-center vehicles, loadage of the vehicles, distribution-center and customer location information, time requirements of goods distribution, supply quantities and demand quantities of all points and priority levels of goods distribution, transportation costs of the enterprise are enabled to be reduced, pollution on environments is reduced at the same time, and sustainable social development is facilitated.

Description

Technical field [0001] The invention belongs to the field of logistics technology, and in particular relates to a vehicle scheduling and route planning method based on environmental protection and cost saving. Background technique [0002] The problem of vehicle scheduling and route planning is a key technology of enterprise transportation. According to the different needs and time requirements of customers, reasonable and efficient scheduling and route planning of enterprise vehicles can reduce costs and improve service quality. With the gradual increase in the country’s emphasis on environmental protection in recent years, the common goal of comprehensive government and enterprises is the foundation of future enterprise development. Therefore, the vehicle scheduling and route planning method based on cost and environmental savings is a cutting-edge scheduling method and a future development trend. In China, many scholars have conducted research and discussion on vehicle schedu...
