Embodiment 1

[0071] This embodiment provides a method for optimizing medical trunk lines, such as figure 1 As shown, the method includes the following steps:

[0072] Use the time-space network model to establish an optimized model for the medical trunk network;

[0073] In order to effectively analyze the time sequence (time constraint) and spatial relationship (distribution of collection points) in this problem, this application adopts the "temporal and spatial network" model to model the medical trunk network. The spatiotemporal network is an extension of the static network, by discretizing the continuous distribution of time at certain intervals, each node represents both a location and a certain point in time. There are two types of arcs (edges connecting nodes) in the space-time network.

[0074] In this embodiment, one week is taken as an example. The designed departure schedule is at least 4 times a week and is a weekly fixed cycle. Therefore, the model divides a total of 168 hours in a ...

Abstract

The invention provides a medical trunk line optimization method and system, equipment and a storage medium. According to the method, a spatial-temporal network model is adopted to perform modeling ona medical trunk line network, wherein the optimal model is based on historical data, an integer programming algorithm is utilized to calculate an optimal relation curve of transportation cost and average time by finding Pareto optimality, and the optimal relation curve is provided off line for planning and selection according to service demands. Through the optimal model, the chronological order and the spatial relation in the medical trunk line network can be analyzed more effectively to optimize departure shifts. A constraint condition of an objective function guarantees that each OD must select one exact spatial-temporal path from optional spatial-temporal paths; a departure arc in each section of the spatial-temporal network has sufficient capacity to bear a corresponding express quantity; and the departure shifts are balanced in counter-departure between two arbitrary cities. Through the optimal model, overall planning can be performed from a global perspective, low-cost and high-timeliness delivery demands are entirely met, and good balance can be reached in terms of overall effect.

Description

Technical field [0001] The invention relates to the field of operations research optimization, and in particular to a method, system, equipment and storage medium for optimizing medical trunk lines. Background technique [0002] With the development of the economy and the advancement of science and technology, the demand for distribution of pharmaceutical products across the country has continued to increase, and gradually occupy a higher market share, while cross-city logistics services have placed extremely high requirements on the trunk network. For some special medicines and certain cities, special car delivery is the most common form. However, for most suppliers and demanders, the demand of a single customer at a certain point in time is very dependent on the trunk line LTL bus network. Take a domestic express company as an example. There are currently 23 urban bus stations nationwide, with at least 4 fixed schedules per week and long-term recurring cycles. Therefore, how to...
