[0055] Step 1: Using the area where the breakwater is planned to be constructed as the target area, establish a finite element or finite volume mesh based on the terrain and water depth. The mesh boundaries should include land boundaries and open boundaries. Land boundaries are boundaries that water cannot pass through, while open boundaries are boundaries that water can pass through. The land boundary of the target area is the land-water boundary of the port. The open boundary of the mesh should be located in the open sea and should be no less than 500 km from the target area to ensure that the non-local effects of wind and waves can be simulated by the model. The mesh resolution of the target area should be no less than 50m to accurately simulate the wave propagation, sedimentation erosion, and water exchange processes in the port waters.

[0056] Step 2: Construct a regional wave, tide, and runoff dataset centered on the target area.

[0057] Step 3: Determine candidate locations for breakwater construction. The candidate locations should comply with the relevant provisions of the Breakwater and Bank Protection Design Code (JTS154-2018) and the Port and Waterway Hydrological Code (JTS 145-2015).

[0058] Step 4: Set construction parameters (including maximum elevation , Cost per unit length of the corresponding design breakwater elevation , Maximum elevation change of a single breakwater , Minimum elevation change of a single breakwater , the highest cost ).

[0059] Step 5: Set the evaluation parameters (including minimum wave attenuation coefficient, maximum construction budget, minimum water exchange rate, maximum sediment erosion / deposition rate, etc.).

[0068] Step 8: Create target constraints:

[0069] These are the constraints of the optimization process, representing the maximum acceptable cost, the maximum rate of breakwater erosion / deposition, the minimum wave absorption coefficient, and the minimum water exchange rate. Solutions that do not violate any of the constraints are considered feasible solutions, while others are considered infeasible solutions.

[0070] Step 9: Randomly assign values ​​to each breakwater section according to the maximum breakwater elevation set by the researcher, and randomly generate N The specific process of generating each breakwater design scheme is as follows: The formula for calculating the elevation of the breakwater at each candidate location is: ,when When it is 0, it means that no breakwater will be built at that location. The set of breakwater elevations at all candidate locations is the generated breakwater design scheme. The expression for calculating the construction cost based on the breakwater design options.

[0072] Step 11: Place all solutions into a pending set and compare them. If a solution A outperforms another solution B on any objective, then B is considered dominated by A. Find all non-dominated solutions in the pending set. These solutions constitute layer 0, the Pareto front of the set. Remove the solutions marked with layer 0 from the pending set. Repeat the marking and removal process for the remaining solutions, extracting one layer at a time, until the pending set is empty.

[0073] Step 12: Compare the Pareto front of the new solution with the existing Pareto front and update the Pareto front.

[0074] Step 13: Calculate the fitness of each solution:

It is in After sorting the objective functions from small to large, the individual No. The sequence number of the objective function. and is an individual No. Two adjacent objective function values. and It is The maximum and minimum values ​​of the objective function in the population.

[0081] Step 14: Take the fitness of each solution As the probability of being drawn, there is a replacement extraction candidate solution until the number of individuals is drawn The samples serve as parents for the next generation.

[0082] Step 15: Continuous gene recombination. First, randomly select one parent as the father and one as the mother, and then select the parent according to the candidate position of the breakwater. Generate a column of random numbers , and then generate a column of random numbers ,in , ,if ,but ,otherwise ,in For The child breakwater elevation at the location, and are the breakwater elevations of the male and female parents, respectively.

[0083] Step 16: Continuous gene mutation. Same as above, based on the candidate position of the breakwater Generate a column of random numbers , and then generate a column of random numbers ,in , ,in , ,for The child breakwater at the position, such as its corresponding random number ,but ,in , is the ratio of the number of feasible solutions in the parent to the total number of solutions. ,but ,if ,but .
