Biometric utility: the degree of suitability of the sample for matching.
The degree of suitability was defined by applying Fuzzy membership function.
He/She provided some functions to measure the degree of suitability of each alternative with respect to a set of criteria presented by vague values.
It includes the detailed evaluation of each item (filled checklists and comments), the actions for suitability suggested, and the degree of suitability of the measurement repository for SPC, which is informed as a percentage.

An important chemical parameter for judging the degree of suitability of water for irrigation is sodium content or alkali hazard, which is expressed as the sodium adsorption ratio (SAR) (Asadollahfardi et al. 2012).

For each exercise within the intervention, the following outcomes (assessed among players and coaches) were measured: (i) degree of relevancy, i.e. added value of the exercises; (ii) degree of suitability of the exercises within training sessions; (iii) degree of usability of the exercises.
On the basis of Wilcox diagram that classifies water samples in terms of degree of suitability for irrigation (Fig. 10), the studied river water in water samples collected in points 4, 6 and 11 belonged to the excellent-to-good and good-to-permissible irrigation water categories.
The degree of suitability of anion exchangers for the sorption of Cr VI) and As V) ions under investigations was also estimated from the values of the separation factor constant (RL) according to the following relation (Langmuir 1916): R_{L} = frac{1}{{(1 + K_{L} C_{0} )}} (12).
