A large scale simulation model for analyzing the production of pipe valves and fittings

This paper describes a large-scale SLAM II-FORTRAN simulation model of a manufacturing plant that produces pipe valves and fittings. The model represents the functional areas of manufacturing (machining, heat treating, electropolishing, assembly, test and material movement) as well as the production planning and control system. The model allows for experimentation in a variety of areas, including production control, capacity planning, and layout design. Results of model experimentation indicate the advantages of conversion to a new single-floor facility over the existing multi-floor facility, as well as the advantages of a reduction in inventory levels for the plant.
