A new concept of adjacency for concurrent consideration of economic and safety aspects in design of facility layout problems

摘要: Abstract In this manuscript a new phenomenon of adjacency and closeness rating is proposed for constructing the optimal facility layout design. approach, applied to every pair neighboring departments in range their attached point up predefined distance between them. Also, while traditional approach determining either proximity or farness two departments, considers both degree as economical purposes, safety purposes concurrently. A mathematical model For evaluating efficiency flexibility model, computational experiment conducted. Through results experiment, three major novelties such its concurrent consideration economic aspects design, ability varieties designs, better implementation among department's pairs during designing processes are demonstrated.
