To manage the constraints, Goldrattproposed five focusing steps (5FS). If we increase constrained output, the output of system will beincreased. In this paper, we focus on step four of the 5FS and use the remained capacity of nonconstraintto elevate the system’s constraint.}, keywords = {theory of constraints,five focusing steps,Queueing system,Threshold}, url = {https://www.ije.ir/article_71882.html}, eprint = {https://www.ije.ir/article_71882_0d197409fe19aa667ab5d9c7b2825ccf.pdf} }
