objective: to systematically review the current literature of simulation in healthcare including the structured steps in the emergency healthcare sector by proposing a framework for simulation in the emergency department. methods: for the purpose of collecting the data, pubmed and acm databases were used between the years 2003 and 2013. the inclusion criteria were to select english-written arti...

Less than a handful of business process software vendors offer optimization to supplement their simulation capability. However, the need for optimization of simulation models arises when the process analyst wants to find a set of model specifications (i.e., input parameters and/or structural assumptions) that leads to optimal performance. On one hand, the range of parameter values and the numbe...

Simulation plays a vital role in analyzing DEDS. However, using simulation to analyze complex systems can he time-consuming and expensive. Particularly, in the case of precise performance evaluation, computing budget, time constraint, and pseudo-random number generator limitations can become prohibitive. Ordinal optimization is an effective approach for improving the efficiency of simulation an...

The ultrasonic transducers have numerous applications in industries, including medical probes for performing ultrasound scans. One of the significant drawbacks transducer is wastage a large portion energy, due to high acoustic impedance, while transmitting waves target object. present study aimed investigate material design piezo-composite and improve its performance. Different were simulated C...
