Question

我正在尝试运行一长串行来优化我的模型的第J列中的“最低成本”解决方案。
列C，D，E和F中有四个变量，从第9行到第50行，以及一些约束。

一般来说VBA相当新，但最初的单行解算器代码如下所示，基本上需要继续重复该过程，然后通过更改变量C10-F10，然后转到第11行等来解决J10。

非常感谢任何开始循环过程的指针！

干杯！

Sub Macro11()
SolverOk SetCell:="$J$9", MaxMinVal:=2, ValueOf:=0, ByChange:="$C$9:$F$9", _
    Engine:=1, EngineDesc:="GRG Nonlinear"
SolverAdd CellRef:="$C$9", Relation:=1, FormulaText:="23"
SolverAdd CellRef:="$D$9", Relation:=1, FormulaText:="23"
SolverOk SetCell:="$J$9", MaxMinVal:=2, ValueOf:=0, ByChange:="$C$9:$F$9", _
    Engine:=1, EngineDesc:="GRG Nonlinear"
SolverOk SetCell:="$J$9", MaxMinVal:=2, ValueOf:=0, ByChange:="$C$9:$F$9", _
    Engine:=1, EngineDesc:="GRG Nonlinear"
SolverSolve
SolverOk SetCell:="$J$9", MaxMinVal:=2, ValueOf:=0, ByChange:="$C$9:$F$9", _
        Engine:=1, EngineDesc:="GRG Nonlinear"

End Sub

输入由表示范围的字符串定义，因此通过与循环变量连接来创建范围字符串：

File "/home/user/projects/project/.venv/lib/python3.6/site-packages/rest_framework/views.py", line 491, in dispatch
    response = handler(request, *args, **kwargs)
File "/home/user/projects/project/companies/views.py", line 83, in add_bank_account
    if serializer.is_valid(raise_exception=True):
File "/home/user/projects/project/.venv/lib/python3.6/site-packages/rest_framework/serializers.py", line 236, in is_valid
    self._validated_data = self.run_validation(self.initial_data)
File "/home/user/projects/project/.venv/lib/python3.6/site-packages/rest_framework/serializers.py", line 434, in run_validation
    value = self.to_internal_value(data)
File "/home/user/projects/project/.venv/lib/python3.6/site-packages/rest_framework/serializers.py", line 458, in to_internal_value
    fields = self._writable_fields

    res = instance.__dict__[self.name] = self.func(instance)

    field for field in self.fields.values()

    for key, value in self.get_fields().items():
