问题如下:

Considering industry changes over the past year, one update that Maxwell should make to the simulation model is the:

选项:

A.

choice of the distribution of CSI and ECI.

B.

relation between CSI and occupancy rates.

C.

removal of constraints on occupancy rates.

解释:

B is correct. Even when the data fits a statistical distribution or when historical data distributions are available, shifts in the market structure can lead to shifts in the distributions as well. In some cases, these shifts can change the form of the distribution, and in other cases, they can change the parameters of the distribution. Thus, relations from historical data for an input may change for the next period, affecting the relation between the nightly room rate and CSI, as well as the relation between the occupancy rate and ECI. The constraints on the occupancy rates are necessary because without them, there may be unrealistic results (such as negative rates or rates exceeding 100%). Further, the choice of the distributions of CSI and ECI is not mentioned to be affected by the changes in the industry over the past year; rather, the relation between CSI and occupancy rates may change.

老师,模拟的这一章节重要吗?这道例题其实我没有看懂,做对的题目完全是记得书上有知识点,做错的是不理解题目问的是什么知识点

同学你好,

这一章相对来说是不重要的一章。而且这章的课后题考察的很奇怪。这章所有的课后题基础班都讲了一遍,可以过一下有个了解就行。

从考试角度出发,优先以掌握上课时讲的这一章的重点概念为主。
