Abstracten Decision making is a very important area of research. In the era of data, the efforts to support decision making by powerful data processing tools are becoming intense. True and in-time decision is of great importance. For this, decision makers need qualified data and qualified processing. Simulation is the reconstruction of real world scenarios in the virtual environment. It makes possible to analyze the different scenarios that is hard or dangerous to accomplish with a trial and error method. This is a simulation case study in which a hardware maintenance service is the subject. The aim of the study is to illustrate how simulation can be used as a valuable decision support tool for managers and directors by first detecting the bottleneck and then find a solution by applying different scenarios. In this study, a hardware maintenance unit of a hospital, which is suffering for long fixing times, is modelled. Data are collected from the system that the hospital uses. Results show that there is a problem in the firm service unit and it can be overcome by increasing the number of personnel.
