Abstract In this paper, we focus on a location-routing problem (LRP) in the dairy industry. This consists of locating cold storage warehouse, from which vehicles limited capacity are dispatched to serve given number supermarkets with uncertain service requirements, and determining order served by each vehicle. First, LRP is solved using classical approach based deterministic model where i.e. cu...

The concept of the neutrosophic hypersoft set (NHSS) is a parameterized family that deals with subattributes parameters and proper extension soft to accurately assess deficiencies, anxiety, uncertainty in decision-making. Compared existing research, NHSS can accommodate more uncertainty, which most significant technique for describing fuzzy information decision-making process. main objective fo...

Let F denote the class of all functions univalent in the unit disk and convex in the direction of the real axis. In the paper we discuss the functions of the class F which are n-fold symmetric, where n is positive even integer. For the class of such functions we find the Koebe set as well as the covering set, i.e. T f2F f ðDÞ and S f2F f ðDÞ. Moreover, the Koebe constant and the covering consta...
