Modelling an economic process

Modelling and simulating economic processes is a discipline that lies on the border to mathematics and informathics and is all about fundamenting the manager's decision in efficiency conditions for the manufacturer, with the help of flexible economic-mathematic models and with the possiblitity of using simulation techniques. Within the simulation activity, three key-elements are involved: the real system, the model (pattern), the computer and two relations: relation and simulation patterns. For the demonstration of those above, we take into consideration the following problem: For a business to carry out its functional conditions at the moment of Romania's adherance to the EU, within an economic section, it needs to accomplish a goal that can be finalized by achieving time/quality indicators withind a well preestablished order.
