Využití simulací k redukci nákladů za telefonování v reálné firmě

This diploma thesis deals with the practical use of simulation models. It is divided into theoretical and practical part. The theoretical part is intended to acquaint the reader with the history of simulation, possibilities of their use and basic starting points for creating simulation models. The content of the practical part is usage of simulation models to solve real problem in a particular company. That is a finding of mobile tariffs to four central office employees of the Executive Board of the Czech Union for Nature Conservation, which would minimize their costs of telephone calls. The data required to create a model was obtained on the basis of previous observations. The entire model was created in the program product Microsoft Excel using the Crystal Ball software addon.
