An intuitionistic fuzzy extension to RAMS-RATMI methods for optimizing electrical discharge machining processes by Srinjoy Chatterjee, Shankar Chakraborty

“…Multi-Criteria Decision-Making (MCDM) approaches have emerged as competent mathematical tools capable of handling multiple input factors and their interactions with numerous conflicting responses to figure out the ideal EDM process parameter values. In this paper, two recently introduced MCDM methods, namely Ranking Alternatives by Median Similarity (RAMS) and Ranking Alternatives by Trace to Median Index (RATMI), integrated with intuitionistic fuzzy sets (IFSs) for taking into account the uncertainty inherent in the opinions of different stakeholders, are proposed in a single framework to optimize two EDM processes. …”

Hybrid and Multi-Hop Advanced Zonal-Stable Election Protocol for Wireless Sensor Networks by Fakhri Alam Khan, Majid Khan, Muhammad Asif, Afsheen Khalid, Inam Ul Haq

“…To reduce this problem, several routing protocols are designed in order to minimize energy consumption and increase the lifetime of the sensor network. In this paper, we introduced a new heterogeneous routing protocol known as advanced zonal stable election protocol (AZ-SEP) in which communication of sensor nodes with the base station is hybrid, i.e., some nodes communicate directly, while others use clustering mechanism to transmit data to base station. …”
