Abstract In the present paper concepts of q-rung orthopair fuzzy mappings (q-ROF mapping) and $( \alpha ,\beta ) $ ( α , β ) -cuts are introduced. Some common fixed point results for q-ROF presented in b-metric spaces using Suzuki-type contra...

This paper investigates a novel fuzzy Petri nets (FPNs) method based on q-rung orthopair sets (q-ROFSs) to provide an efficient solution uncertain knowledge representation and reasoning. It not only improves FPN’s flexibility in parameter reasoning algorithms but also addresses the challenging problem that most FPNs cannot implement backward reasoning, which is common task reversely inferring c...

Supply chain management is to improve competitive stress. In today’s world, terms and customer sense have altered in favor of an environmentalist manner. As a result this, green supplier selection has become very important topic. the approach, agility, lean process, sustainability, environmental sensitivity, durability are pointed. Like classical problems, criteria generally emphasize selection...
