A Direct Approach for Determining the Switch Points in the Karnik–Mendel Algorithm (2017)
Journal Article
Chen, C., John, R., Twycross, J., & Garibaldi, J. M. (2018). A Direct Approach for Determining the Switch Points in the Karnik–Mendel Algorithm. IEEE Transactions on Fuzzy Systems, 26(2), 1079-1085. https://doi.org/10.1109/tfuzz.2017.2699168

The Karnik-Mendel algorithm is used to compute the centroid of interval type-2 fuzzy sets, determining the switch points needed for the lower and upper bounds of the centroid, through an iterative process. It is commonly acknowledged that there is n... Read More about A Direct Approach for Determining the Switch Points in the Karnik–Mendel Algorithm.

Type-2 fuzzy linear systems (2017)
Journal Article
Najariyan, M., Mazandarani, M., & John, R. (2017). Type-2 fuzzy linear systems. International Journal of Granular Computing, Rough Sets and Intelligent Systems, 2(3), doi:10.1007/s41066-016-0037-y

Fuzzy Linear Systems (FLSs) are used in practical situations where some of the systems parameters or variables are uncertain. To date, investigations conducted on FLSs are restricted to those in which the uncertainty is assumed to be modeled by Type-... Read More about Type-2 fuzzy linear systems.

Enhancing evaporative mass transfer and steam stripping using microwave heating (2017)
Journal Article
Ogunniran, O., Binner, E., Sklavounos, A., & Robinson, J. P. (2017). Enhancing evaporative mass transfer and steam stripping using microwave heating. Chemical Engineering Science, 165, doi:10.1016/j.ces.2017.03.003

The effect of microwave heating on evaporative mass transfer of hydrocarbons was investigated for a number of contaminated solid materials. The rate of oil removal could be rationalised by the velocity of steam that was created by selective heating o...

On Nie-Tan operator and type-reduction of interval type-2 fuzzy sets (2017)
Journal Article
Li, J., John, R., Coupland, S., & Kendall, G. (2018). On Nie-Tan operator and type-reduction of interval type-2 fuzzy sets. IEEE Transactions on Fuzzy Systems, 26(2), doi:10.1109/TFUZZ.2017.2666842

Type-reduction of type-2 fuzzy sets is considered to be a defuzzification bottleneck because of the computational complexity involved in the process of type-reduction. In this research, we prove that the closed-form Nie-Tan operator, which outputs th... Read More about On Nie-Tan operator and type-reduction of interval type-2 fuzzy sets.

R-fuzzy sets and grey system theory (2017)
Conference Proceeding
Singh Khuman, A., Yang, Y., John, R., & Liu, S. (2017). R-fuzzy sets and grey system theory. In 2016 IEEE International Conference on Systems, Man, and Cybernetics (SMC)doi:10.1109/SMC.2016.7844949

This paper investigates the use of grey theory to en- hance the concept of an R-fuzzy set, with regards to the precision of the encapsulating set of returned significance values. The use of lower and upper approximations from rough set theory, allow... Read More about R-fuzzy sets and grey system theory.

Multi-objective optimisation in inventory planning with supplier selection (2017)
Journal Article
Turk, S., Özcan, E., & John, R. (2017). Multi-objective optimisation in inventory planning with supplier selection. Expert Systems with Applications, 78, doi:10.1016/j.eswa.2017.02.014

Supplier selection and inventory planning are critical and challenging tasks in Supply Chain Management. There are many studies on both topics and many solution techniques have been proposed dealing with each problem separately. In this study, we pre...
