The aim of this paper was to explore decision-making using Pythagorean fuzzy sets with an acronym in Portuguese for Interactive multi-criteria decision making (TODIM) approach. We propose a novel model that TODIM integrates the technique order preference by similarity ideal solution (TOPSIS) and concepts solve problems related core alternatives facing innovative companies under bullwhip effect ...

This paper presents fuzzy goal programming approach for solving multilevel programming problems with fuzzy parameters. The proposed approach is based on ? -cut and fuzzy goal programming. In the proposed approach, the tolerance membership functions for the fuzzily described objective functions are defined by determining individual best solution of the objective function of every decision maker....

‎in this paper we introduce a numerical approach that solves optimal control problems (ocps)‎‎using collocation methods‎. ‎this approach is based upon b-spline functions‎.‎the derivative matrices between any two families of b-spline functions are utilized to‎‎reduce the solution of ocps to the solution of nonlinear optimization problems‎.‎numerical experiments confirm our theoretical findings‎.

Autonomous multi-agent systems that are to coordinate must be designed according to models that accommodate such complex social behavior as compromise, negotiation, and altruism. In contrast to individually rational models, where each agent seeks to maximize its own welfare without regard for others, socially rational agents have interests beyond themselves. Such models require a new type of ut...

INTRODUCTION Patients suffering from nasal obstruction due to nasal valve compromise may benefit from a nasal dilator. Several devices for widening of the external/internal nasal valve region can be applied endonasally (Airmax, Nasanita, Nozovent) or externally (Breathe Right). MATERIALS AND METHODS 100 patients suffering from nasal obstruction due to external or internal nasal valve compromi...

As the easiest and cheapest way of authenticating an end user, password based approach has been consistently chosen by implementers of every new computer or mobile device based web service. Unfortunately, the explosive growth of web applications has made it impossible for users to manage dozens of passwords for accessing different web services. The situation is even worse considering the potent...

Blockchain technologies, which form the basis of Industry 4.0, paved way for cryptocurrencies to emerge as technological innovation in technology age. Recently, investors worldwide have been interested with increasing acceleration due high earning expectations though they no backing and intrinsic value. As such, this paper seeks identify most proper from an investment standpoint our era. Fiftee...

In this paper a redundancy allocation problem is studied where for the first time the supplier selection is taken into consideration and redundant components are provided from appropriate suppliers with the most suitable offers such as discount on buying price of components, warranty length for components, things like that, so that the system reliability, profit and the warranty length proposed...
