How to predict the number of hotel beds in travel planning?

The calculation formula for predicting the scale of tourist accommodation facilities (number of beds) is as follows:

E=N×P×L/(T×K)

In the formula ：E--Number of beds; N--Annual tourist volume;

P--Accommodation-to-tourist ratio; L--Average number of days of stay;

T--Number of travel days throughout the year ; K--average bed utilization rate.

According to market forecasts, rural tourist areas are expected to receive 2 million tourists annually in 2015. It is predicted that the ratio of tourists staying in rural tourist areas will be about 10%, with an average stay of one day and an average bed utilization rate of about 70%. The number of tourist days in the year is about 260. It is calculated that the number of rural tourism beds in Pixian County in 2015 is about 1,100:

E1=2 million*10%*1/(260*0.7)=1,100
