如何从纸浆模型中提取值

编程问答 2022-06-06

问题描述

```
print("Total Cost:",model.objective.value())
# Decision Variables
for v in model.variables():
    try:
        print(v.name,"=",v.value())
    except:
        print("error Couldnt find value")
```

Total Cost: 1239859526.0
X_Apple = 833167.0
X_Huawei = 100.0
X_Oppo = 100.0
X_Samsung = 35.0

如何从该纸浆溶液中分别提取值？

解决方法

print(dir(prob))打印prob的属性列表

variables和variablesDict在其中：

prob.variables()[0].name
prob.variables()[0].value()

prob.variablesDict()['X_Apple'].name
prob.variablesDict()['X_Apple'].value()
