SIMULATION LANGUAGES AND ITS APPLICATONS</li></li></ul><li>SENSORS<br />A sensor is a device that measures a physical quantity and converts it into a signal which can be read by an observer or by an instrument. <br />For example, a Mercury in glass thermometer converts the measured temperature into expansion and contraction of a liquid which can be read on a calibrated glass tube. <br />A Thermocouple converts temperature to an output voltage which can be read by a voltmeter. <br />For accuracy, most sensors are calibrated against known standards<br />
What is sensor?<br />Non-electrical physical quantity: temperature , sound or light<br />sensors<br />Electrical signal<br />
Electrical and electronicsetc…</li></li></ul><li>sensors<br />
<ul><li>It is a technology, based on computer applications, intended to study the model of this real world system by numerical evaluation software.
It is carried out to evaluate the performance of a system, product or process before it physically built or implemented to imitate or predict the behavior of manufacturing system.</li></ul>SIMULATION<br />
Types of simulation<br />Static or dynamic <br />Continuous or discrete<br />Deterministic or stochastic <br />
<ul><li>Static or dynamic simulation</li></ul>In static simulation time does not have a role.<br />In dynamic simulation time have a role. The most of the manufacturing system are time dependent are hence dynamic<br />
<ul><li>Continuous or discrete simulation</li></ul>System in which continuously varies with time.<br />Eg: refinery, themal power plant and plate glass manufacturing where production is continuous but may fluctuate over time.<br />An automotive assembly plant is more or less a continuous system.<br />A job shop where batch quantity may vary from one to many is a discrete manufacturing plant<br />Eg: machine tool, motor, pumps etc<br />Mixed continuous –discrete system: combination of both<br />
<ul><li>GENERAL PURPOSE LANGUAGES</li></ul>The programs can be written in the high level languages like FORTRAN , C. This approach was popular when simulation languages is not available.<br />The advantage of this approach is the opportunity to design the system to specific application in the customized manner.<br />Disadvantage: very long, time consuming, error prone<br />
<ul><li>SIMULATION LANGUAGES</li></ul>General Purpose Simulation System(GPSS) is one language mainly used for simulation.<br />Mostly declarative languages designed for discrete event simulation and system modeling. It consist of Set of blocks which includes Generators , queues , routers ,data collectors , timing and computational nodes.<br />Includes integers ,real numbers ,strings and records.<br />SIMSCRIPT, SLAM, SIMAN…were latest languages<br />These are very flexible to simulate variety of system<br />
<ul><li>HIGH LEVEL LANGUAGES</li></ul>In addition to above mentioned type ,this is more powerful to graphics user interface, menu and dialog boxes.<br />Standard constructs enable the user to model a system quickly . This make model creation faster.<br />Facility for dynamic graphic animation gives the user to visualize the actual working of the system.<br />
