Abstract
The failure criterion for students in examinations in many universities is based on binary logic, i.e., a student either passes or fails. If the 'pass mark' is fixed at, say 50 marks (out of 100), it follows that a student who scores 49 marks is declared as failed, whereas another who manages to score 50 marks is declared as passed. This is a typical example of an unfair outcome of binary logic. There are shades of grey which lie in between failure and success, and these can be well quantified in the framework of fuzzy logic, which has been widely used in recent years in diverse fields. A 'fuzzy failure criterion' is described in this paper, and with the help of illustrative examples, it is shown how the application of this criterion assists in arriving at more rational and fair decisions in evaluation than are possible using the conventional crisp failure criterion. Based on fuzzy logic, guidelines are also recommended for framing criteria for promotion of students from one level to a higher level, and for deciding the eligibility of students for receiving awards or scholarships.
