Computer simulation is the technique increasingly used to study the predictive behavior of a new or modified system, saving time and economic cost resulting from experiences in the real system. Prof. Rui Assis publishes the book entitled “EXCEL in Systems Simulation and Risk Analysis”. This work deals with themes of Industrial Engineering and describes the steps to be taken in the construction of any model and dozens of application examples supported by 48 EXCEL applications in the areas of Services (waiting lines), Industrial Production, Stock Management, Marketing and Sales, Investment Projects, Project Scheduling, Systems Reliability and Maintenance Policies. The book available from AMAZON supports the Curricular Unit Simulation techniques.
