The students will gain basic concepts of simulation modeling analysis; will learn different specific simulation languages and environments useful in the modeling and simulation of specific problems. The students will be able to: recognize mathematical parameters as if they were physical variables and vice-versa; be able to follow general mathematical concepts of derivation scientific result and possess the mathematical skill to link those concepts; be able to understand the relevance of the mathematical results to real world applications; have the ability to use computational tools for finding graphical, numerical, statistical and analytic solutions to problems; have the ability to use systems simulations appropriate to real world practice; be able to identify input, output, and operating variables as appropriate in various units; be able to identify technical relationships between the input, output and variables and use the relationships to predict mutual changes.

The activity ends with a written final exam (grade E). The seminar homework on computer simulation will be graded (grade S). Students will prepare a software project that will have to illustrate the use of simulation languages to solve a specific task (grade P). The overall students@ activity during the semester will be also considered (grade A). The final grade is the weighted mean of the five grades mentioned above. The final grade = 40%E + 30%S + 20%P + 10%A. Successful passing of the exam is conditioned by the final grade that has to be at least 5.

All university official rules with respect to students@ attendance of academic activities, as well as to cheating and plagiarism, are valid and enforced. Successful passing of the exam is conditioned by grade E to be at least 5.
