This paper presents the optimal allocation for the human resource practices in DMUs (Decision-making units) where each unit has multiple inputs and outputs, the units is classified into two groups: efficient and inefficient. From the literature reviews, scientists suggest a “best allocation approach” without seriously taking into account differences. The question arises the issue which this study would like to explore. This paper deems that the human resource practices are the inputs and the measures of organizational performance are the outputs. From the AHP/DEA (Analytical Hierarchical Process/ Data Envelopment Analysis), it can be found which units have the efficiency. But few papers explore which the variable combination of the human resource and organizational performance can make the efficiency. This study continues to look for the weight of the variables. By the weight of the input and output variables, this study presents the allocation of the human resource practices.
