工程实践:生产调度优化

复杂调度问题建模

    def __init__(self):
        self.objectives = [
            'minimize_makespan',      # 最小化总完成时间
            'maximize_utilization',   # 最大化设备利用率  
            'minimize_setup_time',    # 最小化换型时间

        visual_constraints = self._generate_visual_constraints(machines)
        
        # GLM-4.5V多目标优化
        solutions = self.model.multi_objective_optimize(

    """分析调度方案性能"""
    metrics = {

        self.search_space = search_space
        self.history = []
    
    def bayesian_optimization(self, objective_function, n_iter=50):
        """贝叶斯优化超参数"""
        from skopt import gp_minimize
        
        def wrapped_objective(params):

            model_params = self._params_to_dict(params)
            performance = objective_function(model_params)
            self.history.append((params, performance))
            return performance
        
        result = gp_minimize(
            wrapped_objective,

        return result.x, result.fun
    
    def _params_to_dict(self, params):
        """转换参数格式"""
        param_names = ['learning_rate', 'batch_size', 'num_layers', 'dropout_rate']
        return dict(zip(param_names, params))

# 超参数搜索空间定义
