The Optimum Design on Lottery Schemes
Gao Yun-qing · Gongcheng shuxue xuebao · 2003
The probability of each prize item and the setting of the prize item and the prize were researched, and the effects on rationality of the lottery scheme caused by lottery attraction for lottery fans were also discussed. Two problems were analyzed. In first problem, the 29 schemes were given. Rationality of each scheme was numbered by faint general method and was measured by giving the coefficients to effect on the rational factors, and the result showed that the schemes 26 and 27 are the best schemes, which their rational factor are 0. 5300 and 0.6414. Then the stability of the model was analyzed. In secondary problem, about 29 schemes in the first problem, the rationality of each scheme was computed by linear optimization, which their best rational factor and setting of best prize item were computed by Lingo software. In the final, the other factors about the model were more discussed, and some kind advice was brought forward to management and lottery fan.
