We present a systematic treatment of scattering processes for quantum systems whose time evolution is discrete. define and show some general properties the operator, in particular conservation quasi-energy which defined only modulo $2 \pi$. Then we develop two perturbative techniques power series expansion first one analogous to iterative solution Lippmann-Schwinger equation, second Dyson Quant...

This paper studies and gives an analysis of a particular queuing model. It considers a non-preemptive priority queuing system with K ( ≥ 2 ) classes of jobs. The system consists of a single processor. It represents the model of discrete dynamic scheduling problems associated with M k / Gk / 1 / ∞ endogenous priority queues. The processor schedule jobs arriving according to a Markov arrival proc...

This article proposes an original method for simulation code generation in discrete event systems. This method uses the product location information in the running system. The information flux (product id, location, time) is the starting point for the algorithm to generate a queuing network simulation model.

In this paper, we investigate the fuzzy logic based system characteristics of MX/G/1 retrial queuing system with Bernoulli vacation schedule. The service time and vacation time are assumed to be generally distributed. It is found in many practical situations that the queuing models with fuzzy parameters are much more realistic than the classical crisp parameters based queuing models. We have...

Based on queuing theory we develop analytical approximations for the average packet transfer time of a store-and-forward and a cutthrough buffer insertion ring with two client traffic priorities. These types of rings are architectural alternatives for resilient packet rings (RPR) which transport data (e.g., IP) packets over optical media. We use the approximations for a delay comparison of both...
