Embodiment Construction

[0040] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0041] Such as figure 1 As shown, the present invention is mainly divided into two steps, the first step (step 1-2), collects relevant data of the construction area, builds the duration model library and the system parameter database, and utilizes the discrete event system simulation model to build the construction area transportation system simulation model. The second step (steps 3-4), such as figure 2 As shown, the model in the first step is simulated and calculated several times, and the system parameters are corrected for each simulation, and finally the optimal system parameters, construction cost and construction period are obtained. The detailed steps are as follows:

[0042] Step (1). Collect the duration data of different activities in each time period of the construction area to be tested, identify the collected time data accord...

Abstract

The present invention discloses a simulation method of a dynamic switching-based hydropower engineering transportation system. The method comprises: by collecting data of relevant activities in a construction area, identifying a lasting time model of the activities and constructing a lasting time model library; and molding a transportation system in the construction area by using a simulation model in a discrete event system, and finally performing simulative calculation and analysis. In the course of simulation, a corresponding lasting time model is dynamically selected by determining a time segment of the simulation clock, and system parameters are modified according to a construction progress, thereby implementing a mechanism of dynamic switching. Compared with the prior art, the method according to the present invention can dynamically change the lasting time of the activities according to the specific transportation condition, and more practically simulates the actual transportation system in hydropower engineering, and creates significance to the relevant research.

Description

technical field [0001] The invention belongs to the field of traffic engineering, and relates to a method for simulating a hydropower engineering traffic transportation system based on dynamic switching. Background technique [0002] Most of my country's water conservancy and hydropower projects are located in the mountains and valleys in the central and western regions, with complex terrain and harsh conditions. As an important part of the hydropower project construction site, the transportation system is mainly responsible for the material transportation and management of the project construction. It must not only meet the construction period requirements, but also ensure smooth transportation. It is a key factor in project construction schedule control and cost control. [0003] The traffic and transportation system in the hydropower construction site has the characteristics of complex structure, strong openness, randomness, and many uncertain factors. It is a dynamic and...
