Transportation optimization model of oil products

Transporting massive amounts of oil products, it is essential to optimize the total efforts from leaving origins (refineries) until reaching destinations (depots). In this paper, integer mathematical programming model were developed to satisfy this oil transportation optimization problem. Specifically, it is dedicated to obtain refineries -to-depots optimal assignments by setting distance and cost minimization as the...

Hyers-Ulam stability of non-homogeneous Euler equations of third and fourth order

  The aim of this paper is to prove the stability in the sense of Hyers-Ulam to non-homogeneous Euler equations of third and fourth order: and. It is shown that if fis an approximate solution of any of these equations, then there exists an exact solution of the equation considered near to f.   Key words:  Hyers-Ulam stability, Euler equation, third and fourth order.
