Simulation modeling is being widely used in areas such as manufacturing, health, network communications and military. Such popularity of simulation has resulted in a large number of simulation software tools available on the market. This paper presents the results of a survey on the use of simulation software, which has involved academic and industrial members of the Simulation Study Group of the Operational Research Society of Great Britain. Findings of the survey indicate which types of simulation software are primarily being used, the most common application areas of simulation, users' opinion about software and possible ways of improving simulation software.
