Simulation Note By Tej ShahiPage 2AcknowledgementIt is a great pleasure for me to acknowledge the contributions of a large number of individuals tothis work.I would like to thank all the student of the fifth semester, B.Sc CSIT , batch 3rdand 4thofkathford international college as I used this notesin class.I also would like to acknowledge the author of the booksSystem simulation, 2ndedition byGeoffery Gordon”, andDiscrete - Event system simulation by Jerry Bankform which the mostof the content of this note is prepared.I would like to express my special thanks to staff, faculty and HOD of the Computer Sciencedepartment of Kathford international college for their kind support during the period.
Simulation Note By Tej ShahiPage 3Chapter 1Introduction to Simulation1.What is simulation?Simulation is the imitation of the operation of a real-world process or system over time.Simulation involves the generation of an artificial history of the system, and the observation ofthat artificial history to draw inferences concerning the operating characteristics of the realsystem that is represented.Simulation is the numerical technique for conducting experiments on digital computer, whichinvolves logical and mathematical relationships that interact to describe the behavior and thestructure of a complex real world system over extended period of time.The process of designing a model of a real system, implementing the model as a computerprogram, and conducting experiments with the model for the purpose of understanding thebehavior of the system, or evaluating strategies for the operation of the system.2.System ConceptsA system is defined as a group f objects that are joined together in some regular intraction orinterdependence for the accomplishment of some task. For example:Production system formanufacturing automobiles.A system is usually considered as a set of interrelated factors, which are described as entitiesactivities and have properties or attributes. Processes that cause system changes are calledactivities. The state of a system is a description of all entities, attributes and the activities at anytime.Example: A factory system shown as follows:Components of system2.1 Entity, attribute and activitiesAnentityrepresents an object that requires explicit definition. An entity can be dynamic in thatit moves through the system, or it can be static in that it serves other entities. In the example, thecustomer is a dynamic entity, whereas the bank teller is a static entity.
