In this paper analysis of reduction and dynamic reducts of an information data is presented. The method of reduction in information system is explained first, the information was assumed to be in a two-dimension or in a matrix form. A discernibility matrix of the data was constructed, and then all reducts from that matrix were found. The best (optimum) reduct was selected from all reducts; that was...
The two-stream discrete ordinates method and the two-stream successive orders of scattering method are compared, and the key features of two methods are discussed. Based on the convergence characteristics of successive scattering, we use a semi-empirical model to improve the computing efficiency in the SOS method. Using the delta-M method, we investigate the effect of the two two-stream method for...
We consider the simulation of constrained optimization problem, the (s, S) inventory system with stochastic lead-time and a service level constraint. We allow the orders to cross in time, which makes the problem more complicated. Bashyam and Fu (1998) first present this problem and obtained the answer by using perturbation analysis. Angun, Gurken, Hertog and Kleijnen (2006) studied the same question...
