5、Undertheequallikelihoodcriterion,pleaseselectthebestdecision().

A:HousesB:shoppingcenterC:leasing答案:AI参考:正确答案是C：leasing。\n根据题干中的描述，ColumbiaConstructionCompany需要在建造住宅开发项目、建设购物中心和将公司所有设备租给另一家公司之间做出决策。每个选项的利润取决于材料成本是否稳定或增加。根据给出的表格，按照可能性相等的标准，租赁设备的利润最高，因此最佳选择是C选项。'Inabuscompany,thenumberofstaffs,includingdriversandconductors,requiredforabuslineduringeachtimeperiodisasfollowingtable.Letthestaffsbegintoworkatthebeginningofeachtimeperiodandworkcontinuouslyfor8hours.Howcanyouarrangethestaffingtomeettheworkneedswithaminimumnumberofstaffs?Thenumberofdecisionvariableis（）。

A:7B:5C:8D:6答案:AI参考:通过对题目中给出的信息进行分析，可以得出以下结论：\n\n需要满足工作需求的巴士线路员工人数随时间的变化而变化，其中包含了司机和售票员。为了使员工人数最少，需要合理安排员工的工作时间。\n\n根据表格中的数据，我们可以列出以下决策变量：\n\n*司机：n1\n*售票员：n2\n\n根据题目中的条件，员工需要连续工作8小时，因此可以得出以下方程组：\n\nn1+n2=3\nn1+n2=4\nn1+n2=5\nn1+n2=6\nn1+n2=7\nn1+n2=8\nn1+n2=9\n\n通过观察这些方程，我们可以发现方程组中包含了五个方程和七个未知数，因此选项B中的5个决策变量是不够的。选项A中的7个决策变量是最小的满足工作需求的数量。因此，正确答案是选项A：7。'AfarmerinIowaisconsideringeitherleasingsomeextralandorinvestinginsavingscertificatesatthelocalbank.Ifweatherconditionsaregoodnextyear,theextralandwillgivethefarmeranexcellentharvest.However,ifweatherconditionsarebad,thefarmerwilllosemoney.Thesavingscertificateswillresultinthesamereturn,regardlessoftheweatherconditions.Thereturnforeachinvestment,giveneachtypeofweathercondition,isshowninthefollowingpayofftable,

2、Undertheoptimistic/Maximaxcriterion,pleaseselectthebestdecision().

A:leaselandB:buysavingscertificate答案:AI参考:从给出的选项来看，Iowa的农民正在考虑租赁一些额外的土地或在当地的银行投资储蓄证书。如果明年的天气条件良好，额外的土地将带来丰收，但如果天气条件不佳，农民将面临亏损。储蓄证书的回报率与天气条件无关，始终保持相同的回报。根据这个信息，我们可以通过乐观/最大化标准来选择最佳决策。对于乐观/最大化标准，我们需要找到回报最高的选择。从表格中可以看出，租赁土地的回报在所有天气条件下都高于储蓄证书，特别是在天气良好的情况下，回报更是大幅增加。因此，根据乐观/最大化标准，最佳决策是租赁土地。所以，正确答案是A：租赁土地。'TheAtlanticCoastConference(ACC)hasfourbasketballgamesonaparticularnight.Theconferenceofficew
