Redesign layout of production floor facilities using Algorithm CRAFT

High productivity is the main thing that must be owned by all companies and industry players in meeting the needs of consumers. To increase the productivity of the company must be supported by the smooth process of production, one of the ways is setting the right plant layout because it affects the cost of the production process. A cracker maker manufacturing company has constraints in layout arrangements that result in inefficiency in production and distance which results in high material handling costs so that a layout redesign has to be done to minimize material handling costs. The design of the production floor facility layout is done by CRAFT algorithm with the help of WinQSB software. The results of the study found that alternative proposals that provide a reduction result of 9.21% or equal to Rp 6,781,236, - per batch of the total cost of material handling initial layout.
