Document Summary
A simulation is a mathematical model of a real world processor system. This is what we used in business decision models in chapter1. It is the more sophisticated version of a bdi. We study si(cid:373)ulatio(cid:374)s (cid:271)e(cid:272)ause we (cid:272)a(cid:374) study the syste(cid:373)"s (cid:272)hara(cid:272)teristi(cid:272)s a(cid:374)d u(cid:374)dersta(cid:374)d how (cid:272)ha(cid:374)ges will affect the system. Step 1: document a system using a flow chart this is the hardest thing, if you cant do this you cant do anything. Step2: there will be uncertain events in the flow chart so we need probability distributions. We assign random number (customers) to each probability distribution. Step 3:random number probability distribution ( we assign customers) Step 4: use the flowchart to develop a mathematical model of the system. Simulations can be done using pencil-paper or excel or simquick, crystal ball. As you read the problem, think about what the flow chart will look like.
