我目前正在尝试解决这个问题。我需要使这家公司的利润最大化。
这就是我目前拥有的代码：
from pyomo.environ import *
from pyomo.opt import *
opt = solvers.SolverFactory("ipopt")
model = ConcreteModel()
model.x1 = Var(within=NonNegativeIntegers)
model.x2 = Var(within=NonNegativeIntegers)
model.y1 = Var(within=NonNegativeIntegers)
model.y2 = Var(within=NonNegativeIntegers)
model.b1 = Var(within=Boolean)
model.b2 = Var(within=Boolean)
model.c1 = Constraint(expr = model.x1 + model.x2 + model.y1 + model.y2 <= 7000)
model.c2 = Constraint(expr = 2*model.x1 + 2*model.x2 + model.y1 + model.y2 <= 10000)
model.c3 = Constraint(expr = model.x1 <= 2000)
model.c4 = Constraint(expr = model.x2 <= 1000)
model.c5 = Constraint(expr = model.y1 <= …pyomo ×1
