Embodiment Construction

[0038] see figure 1 , the simulation steps of hydropower engineering transportation simulation in this simulation optimization algorithm invention are as follows:

[0039] Step1: Start the simulation, and read in engineering data such as earthwork transportation plan and road information;

[0040] Step2: Initialize various simulation parameters;

[0041] Step3: Generate a dynamic loop network of dump trucks driving in the transportation system;

[0042] Step4: Set the start time of the system simulation clock;

[0043] Step5: Scan all flow entities to determine the leading entity corresponding to the next earliest event; if there is no leading entity, go to Step 15;

[0044] Otherwise, execute Step 6;

[0045] Step 6: Determine whether the current leading entity is in the queuing queue, if not in the queue or is the head element, then execute Step 7; otherwise, accumulate the current

[0046] Queuing time of the former dominant entity, and go to Step 5;

[0047] Step 7: ...

Description

technical field [0001] The present invention relates to a hydropower engineering transportation simulation optimization algorithm, specifically a method for integrating computer simulation technology and heuristic optimization algorithm. Group the optimal transportation machinery configuration scheme to provide decision support for engineering decision makers. Background technique [0002] At present, with the development of computer technology, simulation theory and system engineering technology, it has become possible to establish the simulation and visualization performance of large-scale engineering construction transportation system. Transportation is a highly complex stochastic process, and it is very effective to use simulation technology to describe this time-varying and complex stochastic process. However, the simulation model is only an intuitive description of the problem, and the simulation operation can only provide a feasible solution under certain conditions,...
