چکیده
In this paper, we present a simulation testbed for wireless and mobile telecommunication systems, a two-stage PCS parallel simulation testbed which makes use of a conservative scheme at Stage 1, and of time warp at Stage 2. While Time warp is considered to be an effective synchronization mechanism in parallel and distributed discrete event simulation (PDES) it is also well known for its unstability due to rollbacks and its devastating effect, i.e., serie of cascading rollbacks, among other factors. Thus, our primary goal in this paper is to study the impact and the importance of partitioning in our PCS model while reducing significantly the number of rollbacks.

A multi-objective genetic algorithm for a mixed-model assembly U-line balancing type-I problem considering human-related issues, training, and learning
Mixed-model assembly lines are increasingly accepted in many industrial environments to meet the growing trend of greater product variability, diversification of customer demands, and shorter life cycles. In this research, a new mathematical model is presented considering balancing a mixed-model U-line and human-related issues, simultaneously. The objective function consists of two separate com...

متن کاملDynamic Performance Analysis of Hysteresis Motors by a Linear Time-Varying Model
Hysteresis motors are self starting brushless synchronous motors which are being used widely due to their interesting features. Accurate modeling of the motors is crucial to successful investigating the dynamic performance of them. The hysteresis loops of the material used in the rotor and their influences on the parameters of the equivalent circuit are necessary to be taken into considerat...
