Hofacker 1, D. Gandhi2  \nABSTRACT  \nStructural Steel Fabrication is a process in which there is a wide variety of product mix and where most of the products are unique in nature. A lot of work has been done to analyze the use of Discrete Event Simulation in various manufacturing and construction projects for application of lean concepts and other purposes to detect opportunities for optimization. However, there is a lot of different Discrete Event Simulation (DES) Software available in the market. After a first evaluation, 5 different software tools were selected that all claim to identify bottlenecks in processes and optimize or improve them. This paper specifically takes the complexity of Structural Steel Fabrication Process into consideration and uses these 5 different Software Simulation tools available to model these processes. It not only shows the need for using simulation for better production planning and layout-decisions during execution to improve productivity, but also compares these Softwares, in order to help Simulation practitioners to make informed decisions on software selection based on the mentioned parameters for comparison.  \nKEY WORDS  \nDiscrete Event Simulation, Steel Fabrication, Structural Steel, Process modeling, Software Comparison, Productivity analysis, performance metrics  \nINTRODUCTION  \nSteel is being used in most of the construction projects because of the flexibility, speed of erection and the economic benefits that it provides for the designers and the contractors (AISC 1998) . Structural Steel is mostly fabricated in controlled shop environments off-site, for better precision and accurate detailing and manufacturing. The different parts are then grouped together as modules at steel-fabricators and then assembled on the construction site. The complexity of Steel Fabrication process is originated in the uniqueness of steel projects like bridges, car parks, power-plants, etc. This makes processing, routing and resource or labor requirements different for each product within a steel fabrication shop floor. Hence, Steel Fabrication is a project based industry with low repetitiveness in production and a diverse range of products.  \nAlthough knowing all the complexities involved in structural steel fabrication, currently still in most fabrication shops planning, scheduling and estimating activities are left totally on the personal experiences of Production engineers and managers. The only tools used by most fabrication shops for estimating and scheduling are CPM/PERT along with the available  \n1 Research Associate, Institute of Technology and Management in Construction (TMB), Karlsruhe University (TH), Germany, Am Fasanengarten Geb. 50.31, D-76128 Karlsruhe.

However, these tools offer a very limited opportunity to evaluate the different possible scenarios that take into account the many options that each product has across the shop floor and also the way in which available resources are utilized. Moreover, these tools don’t show waste and non-value adding time. Hence they are not adequate to manage the production flow, to detect potential for production improvement and to optimize the performance of the material flow.  \nSimulation tools can imitate the operations of real-life systems or processes to almost any amount of detail required.
