【DPFSP问题】基于斑马优化算法ZOA求解分布式置换流水车间调度(DPFSP附Matlab代码

在Matlab中，ZOA（Zoom Optimization Algorithm）可以用来求解DPFSP（Distributed Permutation Flowshop Scheduling）问题。以下是一个简化的Matlab代码示例，展示了如何使用ZOA求解DPFSP问题的框架：

function [best_sol, best_cost] = zoa_for_dpfsp(problem, params)
    % 初始化种群
    pop_size = params.pop_size;
    population = init_population(problem, pop_size);
    
    % 迭代次数
    max_iters = params.max_iters;
    
    % 存储最优解
    [best_sol, best_cost] = get_best_sol(population);
    
    for iter = 1:max_iters
        % 计算适应度
        fitness = calculate_fitness(population, problem);
        
        % 选择操作
        selection_prob = calculate_selection_prob(population, fitness);
        offspring = selection(population, selection_prob);
        
        % 交叉操作
        for i = 1:pop_size
            if rand() < params.pc
                cross_over_points = randperm(problem.n-1);
                cross_over_points = [1 cross_over_points+1];
                offspring{i} = cross_over(population{i}, offspring, cross_over_points);
            end
        end
        
        % 变异操作
        for i = 1:pop_size
            if rand() < params.pm
                offspring{i} = mutation(offspring{i}, problem);
            end
        end
        
        % 更新种群
        population = offspring;
        
        % 更新最佳解
        [best_sol, best_cost] = get_best_sol(population);
    end
end
 
function population = init_population(problem, pop_size)
    % 初始化pop_size个个体
    population = cell(pop_size, 1);
    for i = 1:pop_size
        population{i} = randperm(problem.n);
    end
end
 
function fitness = calculate_fitness(population, problem)
    % 计算适应度，这里需要实现DPFSP的适应度函数
end
 
function selection_prob = calculate_selection_prob(population, fitness)
    % 计算选择概率
end
 
function offspring = selection(population, selection_prob)
    % 根据选择概率进行选择操作
end
 
function offspring = cross_over(parent, offspring, cross_over_points)
    % 实现交叉操作
end
 
function offspring = mutation(individual, problem)
    % 实现变异操作
end
 
function [best_sol, best_cost] = get_best_sol(population)
    % 寻找种群中最佳的个体
end

这个代码框架提供了ZOA求解DPFSP问题的基本步骤，包括初始化、计算适应度、选择、交叉和变异操作，以及更新最优解。具体的DPFSP适应度函数、选择方法、交叉策略和变异策略需要根据问题的具体细节来实现。
