Redesigning the layout with algorithm craft on boiler manufacturing

Abstract

Smooth production flow must be considered in planning the production floor layout. Good design of manufacturing facilities can increase effectiveness and efficiency through reducing material transfer distances, material handling costs and cycle times used. A boiler-making industry has constraints in the preparation of machinery so that back tracking occurs which has an impact on long cycle times and increased material handling costs. So this research was conducted to redesign the layout using the graph method and the CRAFT algorithm. And the results of the layout design of the two methods are done by comparing the moment of displacement. The design of the proposal using the CRAFT algorithm provides an increase in time efficiency of 8.95% or the equivalent of 1598 minutes per product and the cost of material handling fell by Rp 47,403.90 / year.
