methyl tertiary butyl ether (mtbe) is known as a promising substitute for tetra ethyl lead (tel) in order to increase the octane number of gasoline. mtbe process, as many other processes, has two distinguished section, namely reaction section and separation section. in this paper we focus only on synthesis and optimization of separation section of this process. in order to achieve this objectiv...

Business process simulation is an important means for quantitative analysis of a business process. With the Business Process Model and Notation (BPMN) being the state-of-the-art language for the graphical representation of business processes, a variety of process simulators exist which already support the simulation of BPMN process diagrams. However, they do not provide well-defined interfaces ...

in the present study, a model of a large lithium polymer (li-po) battery for use in the simulation of hybrid electric vehicles (hevs) is developed. to attain this goal, an equivalent circuit (ec) consisting of a series resistor and two rc parallel networks is considered. the accuracy and the response time of the model for use in an hev simulator are studied. the battery parameters identificatio...

A reliable dynamic simulator (based on a sound process model) is highly desirable for optimizing the performance of individual membrane modules and of entire desalination plants. This paper reports on progress toward development of a comprehensive model of the complicated physical-chemical processes occurring in spiral wound membrane (SWM) modules, that accounts for the...

Alaska Simulator is an interactive software tool developed at the University of Innsbruck which allows people to explore different approaches to process flexibility by using a familiar metaphor, i.e., travel planning and execution. In addition, Alaska Simulator is used for studying research questions in the context of business process management and other related fields. For this, Alaska Simula...

promises shorter time-to-market and decreased life cycle cost. However, those benefits are not guaranteed under every situation and are affected by many factors, such as number of available employees, market demands, reuse rate, process maturity, and product line adoption and evolution approaches. Before initiating a software product line, an organization needs to evaluate available process opt...
