我创建了一个带有if流量控件的函数,我想知道一些关于它的事情。
class Supplier(Process):
def weeklySupply(self):
global D1Vals
xMeet = D1Vals[0]
lead = 0
capac = 150.0
supply = 0
if stocked.amount >= 15000:
supply = 0
yield put, self, stocked, supply
S1Vals.append(0)
elif supply >= capac:
supply = capac
yield put, self, stocked, supply
S1Vals.append(capac)
else:
supply = random.triangular(.70 * xMeet , xMeet , xMeet * 1.05)
yield put, self, stocked, supply
print ('Week:'+'%6.0f:Supplied: %6.0f units. CurSupply = %6.0f' %
(now() + 1., supply, stocked.amount))
yield hold, self, lead
S1Vals.append(supply)
del D1Vals[0]
我编码的是:
如果库存对象中的金额>> 15000,则该对象生成零供应 或者,如果产生的供应值大于预定义的“容量”,则供应值='容量'。
如果上述情况不属实,则将供应值作为随机分布生成。当我得到我的输出时,供应值确实超过150的“容量”值。
我是否误解了如何进行流程?

不要像你在问题中那样将if elif
构造与某种or
混淆。仅当elif
条件为if
时,才会评估False
条件。
我想,你真正想要的是:
if stocked.amount >= 15000:
if supply >= capac:
supply = capac
yield put, self, stocked, supply
S1Vals.append(capac)
else:
supply = 0
yield put, self, stocked, supply
S1Vals.append(0)
else:
supply = random.triangular(.70 * xMeet , xMeet , xMeet * 1.05)
...
但是,如果supply
在函数开头没有初始化为0,那么这只会起作用。
答案 1 :(得分:0)
似乎是一种享受,以及一些让我思考的好东西。我能看到的唯一问题是现在我的S1Vals列表已停止将零电源附加到列表中。我可以在输出图表上看到这个,也可以在我做一个len(S1Vals)时看到这个。最终的代码是您的建议:
if stocked.amount >= 15000:
if supply >= capac:
supply = capac
S1Vals.append(capac)
yield put, self, stocked, supply
else:
supply = 0.0
yield put, self, stocked, supply
S1Vals.append(supply)
else:
supply = min(capac, random.triangular(.70 * xMeet , xMeet , xMeet * 1.05))
yield put, self, stocked, supply
print ('Week:'+'%6.0f:Supplied: %6.0f units. CurSupply = %6.0f' %
(now() + 1., supply, stocked.amount))
yield hold, self, lead
S1Vals.append(supply)
del D1Vals[0]
为了到达此处,我使用了MaxPower上面的流量建议,也是min(supply,capac)
,并声明了global supply
。最后一个问题似乎supply = 0.0
从未开始,但它应该真的吗?
