چکیده
Companhia Siderúrgica de Tubarão CST, is investing to expand production level in 50%, adding new equipment and altering production process. Simulation is widely used in CST, mainly in strategic phases prior to capital investment. A previous simulation model developed with ARENA was enhanced to help CST achieve new goals: to analyze new process plan with operational details, testing different production and operational scenarios, evaluating new procedures and best practices. Two case studies are presented here to show how CST uses this technology: the expansion of an steelmaking plant and the expansion of the raw material handling conveyor system.

Optimization of production systems through integration of computer simulation, design of experiment, and Tabu search: the case of a large steelmaking workshop
The objective of this study is to optimize the performance of discrete production systems by integration of computer simulation, design of experiment (DOE), and Tabu search (TS). Optimizing performance of a steelmaking workshop was considered as the case of this study, but it could be used to optimize the throughput of other production system. The simulation model is built by considering all ma...
متن کاملFoamy Slag Fundamentals and their Practical Application to Electric Furnace Steelmaking
This paper will define the slag compositions required to obtain and control optimum foamy slag conditions in the Electric Furnace. In defining the optimal slags, consideration is given to the effects of scrap quality, carbon injection, slag basicity and MgO content. A computer model based on published phase-diagrams has been developed which graphically maps the chemistries for optimal foaming c...

متن کاملEffects-Based Air Operations Planning Framework: A Knowledge-Based Simulation Approach
Planning air warfare operations has always been a complex endeavor. However, as technology evolves at an increasingly fast pace, so does the complexity of managing its resources. In modern air operations, planners have to deal with a highly changing environment influenced by enemy air defenses, weather forecasts, among many other factors, demanding much effort to handle the great number of cons...
متن کاملAn integrated simulation-DEA approach to multi-criteria ranking of scenarios for execution of operations in a construction project
The purpose of this study is to examine different scenarios for implementing operations in the pre-construction phase of a project, based on several competing criteria with different importance levels in order to achieve a more efficient execution plan. This paper presents a new framework that integrates discrete event simulation (DES) and data envelopment analysis (DEA) to rank different scena...
