Pay structure is the ordering of pay rates for jobs or groups of jobs within an organization and plays an important role in the employment relationships affecting the efficiency of an organization. Design of a pay structure is a complex process requiring the evaluation many factors including both quantitative and qualitative data. Grey Relations Analysis (GRA) a useful mathematical tool for dealing with uncertainty and system analysis with limited information is introduced for creating a pay structure. Fuzzy Analytical Hierarchy Process (FAHP) is also used to determine the factor weights of payment types by pair-wise comparisons. The hypothetical case study shows the applicability of the model.
