Python+Gurobi求解案例

模型描述

下面是一个工厂的生产计划模型。模型的集合、参数、决策变量与数学模型描述如下：

编程求解

 模型参数通过一个简单的测试数据给出，模型是在python里面从零开始建立，最后输出结果。代码如下：

import gurobipy as gp
from gurobipy import GRB

#production rate of machine k at facility m
pro_rate = [5,5,5,4,4,4,3,3,3,3]

#total capicity of machine k at facility m
capicity = [30,30,30,30,30,30,30,30,30,30] 

#usage cost per unit of machine k
usage_cost = [3,3,3,2,2,2,1,1,1,1]

#number of worker required for machine k
woker_req = [3,3,3,3,3,3,3,3,3,3]

#energy consume cost of factory m
energy_cost = 20

#number of fixed worker at factory m
fixed_worker = 21

#labor cost per unit time of fixed worke
