This paper deals with estimations of probabilities of rare events using fast simulation based on the splitting method. In this technique, the sample paths are split into multiple copies at various stages in the simulation. Our aim is to optimize the algorithm and to obtain a precise confidence interval of the estimator using branching processes. The numerical results presented suggest that the ...

The event-scheduling view of the discrete-event simulation technique is widely used to model and simulate dynamic systems. This paper presents DMOD, a formalization of this technique. It ooers two main advantages. First, it retains the powerful intuitions behind this technique yet makes it easier to use them. In particular, it proposes a new method for logically specifying event preemption. Sec...

Abstract The stability control of suspension density is an important means to ensure the quality fine coal in dense medium separation (DMS) process. This paper focuses on tracking issue a non‐uniform sampling and networked environment, proposes multi‐rate event trigger design method. Firstly, lifting technique identification method are adopted establish model. Secondly, event‐triggered predicti...

this paper presents the formulation and solution of the combinatorial multi-mode resource constrained multi-project scheduling problem. the focus of the proposed method is not on finding a single optimal solution, instead on presenting multiple feasible solutions, with cost and duration information to the project manager. the motivation for developing such an approach is due in part to practica...

Studying a system using discrete-event computer simulations implies several activities: conceptual model speci cation, software model architecture description, software development, simulation scenario, instrumentation, experimentation planning, computational resources con guration, execution, post-processing and analysis, validation and veri cation (V&V). Many software are required to complete...
