Computerized Relative Allocation of Facilities Technique (CRAFT) methodology was utilized in this case as part of the strategy to portrait the relationship between each department to generate improved layout alternatives.

• The main objective of the CRAFT is to apply multidisciplinary concepts; tools and technique to solve organizational problems and to evolve innovative theoretical frame work.
• In this work the present layout of the foundry section is improved (CRAFT).
• The model of the proposed improvement layouts will be modeled using ARENA.
• The models will be validated and verified. Experimentation of each layout proposal will be done using the simulation model.
• The results will be analyzed and compared with the existing layout
• It starts with an initial layout and improves the layout by interchanging the department pair wise so that the transportation cost is minimized.
• The algorithm continues until no further interchanges are possible to reduce the transportation cost.
