Derivation of the relationship between logistics customer service and revenues

As the derived shape of the logistics customer service-revenue curve is of qualitative nature, a quantification of that relationship is called for. The exact curve progression is determined by surrounding conditions like product, customers, industry or company (Hsin-Hui et aly 2009 112, 121 ). The below introduced fuzzy-based model ascertains the curve progression considering these fEictors.
