\(\lambda \)-possibility-center based MCDM technique on the control of Ganga river pollution under non-linear pentagonal fuzzy environment

Indians regard the River Ganga as religious because it sustains the ecosystem and ecology. Over the past few decades, human activities have caused significant changes in the Ganga river system. Ganga pollution’s leading cause is the need for more management of drainage and industrial design in the metropolitan cities of India. Therefore, in this paper, we have developed a \(\lambda \) -possibility-center based multi-criteria decision-making method under a fuzzy environment. With this decision-making technique, we have found which causes one of three leading causes of Ganga river pollution Disposal of industrial waste into the river, Human sewage and animal waste and Increasing population density. \(\lambda \) -possibility MCDM technique can deal the how to control the Ganga river pollution. Finally, we have Ganga river pollution with \(\lambda \) -possibility MCDM technique under a non-linear pentagonal fuzzy environment.
