A black-box solver for the solution of nonlinear functional equations is a compromise of exibilty, eeciency and stability of the algorithms. We will present a general form of functional equation, a general error indicator and the eecient interaction of the error indicator and the Newton-Raphson iteration during the solution of the problem arising from the discretization by mixed nite element me...

The development of artificial intelligence and the recent COVID-19 pandemic as well emergence other diseases has led to dramatic changes in overall supply chain development. choice a suitable supplier will be key ensuring sustainable company normal operation chain. However, evaluation data selection contains both qualitative quantitative simultaneously. In addition, information provided by expe...
