EIQNK curve analysis for the design of distribution center and warehouse with spline function

This paper discussed the EIQ and EIQNK curve metohd for the selection of machine and equipments in the design of distribution center or warehouse.This curve are expressed with orthogonal polynominals and spline functions and how the function applied of this problems.The shape of EIQNK curves are split into differents classes and discussed the characteristic of warehouse or distribution. Fuzzy EIQNK curve analysis also discussed.
