The system M/G/1/N was studied. Steady queue index are obtained by using probability analysis and supplementary variable method. The result of M/D/1/N is applied to solid garage. The research of actual example indicates that owner of car can not wait long time when they take their car in solid garage if their arrival is Poisson flow and interval time is enough longer then service time.
In present paper, the measure of probability is introduced to the non-empty finite universe, and the probability rough sets model between different universes is defined. Furthermore, some basic properties of it are built. Additionally, the relationships between the probability rough sets model that is defined in this paper and the other rough set model is investigated, too. The result shows that the...
