In the multivariate statistical process control literature, the profile is a function or curve representing the relation between two or more variables. Several types of complicated curves are conventionally applied to analyze the health of humans, such as Systolic and Diastolic blood pressure profiles. This paper proposes a new approach to interpreting the process capability indices of complex health profiles in the human body performance assessment. Using the popular multivariate statistical techniques of profile monitoring for complex health profiles is too complicated or impossible. Hence, the proposed method transforms the health profile into a univariate specification using dissimilarity indices. The applicability of the new approach is verified via a simulation study on an example of human blood pressure profiles. This application also represented the simplicity of the proposed method to conventional techniques and how the profile capability indices could be applied in the health evaluation. In addition, it provides valuable information to evaluate the heart performance in terms of blood pressure and make a judgment on the blood circulation system.
