【优化求解】基于matlab求解小区基站选址优化问题【含Matlab源码 439期】

一、简介

基于matlab 小区基站最优化选址问题

二、源代码

function [C,P] = GetPlan()
clc
clear

Get_OptimalCombination(1);
Get_OptimalCombination(2);
Get_OptimalCombination(3);
Get_OptimalCombination(4);
Get_OptimalCombination(5);
   
end

%function [Plan_BuildStation, Plan_BuildCost, Plan_CoverCommunity, Plan_CoverPeople] = Get_OptimalCombination(SelectNum)
function Result = Get_OptimalCombination(SelectNum)

    %基站建设费用
    Cost = [1.8, 1.3, 4.0, 3.5,3.8,2.6,2.1];
    %基站对应的社区
    BaseStation_Community = [1,2,4,0,0; 2,3,5,0,0; 4,7,8,10,0; 5,6,8,9,0; 8,9,12,0,0; 7,10,11,12,15; 12,13,14,15,0];
    %社区对应的人口数
    Community_Person = [2, 4, 13, 6, 9, 4, 8, 12, 10, 11, 6, 14, 9, 3, 6];

    CB_num = combntns(1:7, SelectNum);%求排列组合数
    [Size_row, Size_column] = size(CB_num);%求组合的行数和列数
    CB_num;%测试项
    %求出每种组合的价格
    for i = 1:1:Size_row
        Build_Cost(i) = 0;
       for j = 1:1:Size_column
           Temp1 = Cost(CB_num(i,j));
           Build_Cost(i) = Build_Cost(i) + Temp1;
       end
    end
    Build_Cost;%测试项    
    %判断是否超出预算,并删除不符合要求的组合
    abcd1 = 0;
    for i = 1:1:Size_row
       if Build_Cost(i) > 10
            abcd2 = i;
            abcd1 = [abcd1 abcd2]; %取出不合适的序号        
       end    
    end
    abcd1(:,1) = [];%删除第一项0
    for i = length(abcd1):-1:1
        abcd1(i);
        CB_num(abcd1(i),:) = [];
        Build_Cost(:,abcd1(i)) = [];
    end
    [Size_row, Size_column] = size(CB_num);%更新数组参数  
    if Size_row == 0
        return;
    end
    %求每种组合覆盖的社区
    for i = 1:1:Size_row
       Temp2 = 0;
       for j = 1:1:Size_column;
           Temp3 = BaseStation_Community(CB_num(i,j),:);
           Temp2 = [Temp2 Temp3];%数组组合
         
           Cover_Community{i} = Temp2(Temp2~=0);%组成元包数组
       end
    end
    Cover_Community{1};%测试项
    %Cover_Community{1}(:,4)
    %求覆盖的人数
    for i = 1:1:Size_row
       Temp4 = Cover_Community{i};
       Temp6 = 0;
       for j = 1:1:length(Cover_Community{i});
           Temp7 = Cover_Community{i}(:,j);%读覆盖的社区
         
           Temp6 = Temp6 + Temp5;%求和
           Plan_TotlePeople(i) = Temp6;
       end
