In this paper, we propose a new measurement metric of love/attraction between a male and a female for getting married based on a few inputs by using fuzzy logic technology. A difference in physical attraction, social status and success in their respective fields are necessary to be measured for the calculation of love. As the behaviours and status of persons are full of uncertain, fuzzy logic technology is a perfect to be used in this context. In this paper, all the inputs are taken as fuzzy, and finally, the measurement metric of love is formulated by using a fuzzy inference system. A survey in a semi-urban place Tamluk, West Bengal, India is conducted, and their love value is calculated based on the proposed approach. Our new measurement metric of love value will replace the matchmakers in traditional marriage, especially in the survey place. We hope that this approach will also stimulate future studies on fuzzy logic based measurement metrics.
