In stochastic programming and decision analysis, an important issue consists in the approximate representation of the multidimensional stochastic underlying process in the form of scenario tree. This paper presents the approach to generate the multistage multidimensional scenario tree out of a set of scenario fans. For this purpose, the multistage K-means clustering algorithm is developed. The ...

Many actual multistage manufacturing processes are not serial structure, but parallel structure or hybrid structure. The quality relationship model for multistage manufacturing process with parallel structure was developed based on state space model. The quality relationship model of multistage manufacturing process with hybrid structure was developed via the hierarchical iteration method based...

The design of constrained multirate systems using a relative ` error criterion is considered. A general algorithm is proposed to solve the problem. One application of the algorithm is the design of a new class of multirate lters for signal decomposition{projection lters. These multirate systems are projection operators that optimally approximate linear time-invariant lters in the ` norm. A seco...

In parallel/distributed computing systems, the all-to-all personalized communication (or complete exchange) is required in numerous applications of parallel processing. In this paper, we consider this problem for logN stage Multistage Interconnection Networks (MINs). It is proved that the set of admissible permutations for a MIN can be partitioned in Latin Squares. Since routing permutations be...

The notion of indirect separability is exploited to derive a new multistage demand system. The model allows a consistent parameterization of demand relations at various budgeting stages and it fulfills the requirement of flexibility while satisfying separability globally. Two propositions are derived to characterize flexible and separable functional forms, which lead to the specification of a f...

Omega Networks are a famous subclass of blocking Multistage Interconnection Networks (MINs). They have been recently identified as an efficient interconnection network for a switching fabric of communication structures such as gigabit ethernet switch, terabit router, and ATM switch. Interconnection network performance is also a key factor when constructing multiprocessor systems. In this paper ...

Multistage stochastic optimization leads to NLPs over scenario trees that become extremely large when many time stages or fine discretizations of the probability space are required. Interior-point methods are well suited for these problems if the arising huge, structured KKT systems can be solved efficiently, for instance, with a large scenario tree but a moderate number of variables per node. ...

In digital signal processing, decimation is a technique for reducing the number of samples in discrete-time signal used for multi-rate signal processing in wireless communication systems. In this paper optimized decimator has been presented to improve the implementation complexity. The proposed decimator is implemented using MATLAB as standard FIR, Half Band FIR and Nyquist FIR by using the mul...
