Implementing Parallelism in Random Discrete Event-Driven Simulation
نویسندگان
چکیده
The inherently sequential nature of random discrete eventdriven simulation has made parallel and distributed processing di cult. This paper presents a method of applying Recon gurable Logic to gain some parallelism in event generation. Field Programmable Gate Arrays (FPGAs) are used to create a exible and fast environment in which events may be generated according to various statistical models. The method presented accelerates both event generation and the elimination of some blocked events from the Event Queue.

Appointment process of open-heart surgery in Shahid Rajaei Heart Hospital using a discrete event simulation approach
Background: The waiting list is a list of selected patients in the surgical queue. If demand exceeds capacity, the waiting list grows rapidly, which may lead to unacceptable waiting for patients, especially those in need of acute medical care. Patients waiting for heart surgery are placed on the waiting list for surgery, and sometimes the waiting time is longer than patients expect. Reducing th...
متن کاملHybrid Probabilistic Search Methods for Simulation Optimization
Discrete-event simulation based optimization is the process of finding the optimum design of a stochastic system when the performance measure(s) could only be estimated via simulation. Randomness in simulation outputs often challenges the correct selection of the optimum. We propose an algorithm that merges Ranking and Selection procedures with a large class of random search methods for continu...

متن کاملSynchronous Parallel Discrete Event Simulation on Shared-Memory Multiprocessors
This paper describes the implementation and studies the performance of a synchronous , parallel discrete event simulation (SPDES) method on a shared memory multiprocessor. The presented method aims at the eecient simulation of architectural designs for which the asynchronous PDES methods seem to be less eeective. A multiprocessor machine is simulated, and the performance achieved is compared to...

This paper, considers Network Failure Manufacturing System (NFPMS) and production control policy of unreliable multi-machines, multi-products with perishable items. The production control policy is based on the Hedging Point Policy (HPP). The important point in the simulation of this system is assumed that the customers who receive perishable item are placed in priority queue of the customers w...
