in this paper, a new numerical method for solving fractional optimal control problems (focps) is presented. the fractional derivative in the dynamic system is described in the caputo sense. the method is based upon biorthogonal cubic hermite spline multiwavelets approxima-tions. the properties of biorthogonal multiwavelets are first given. the operational matrix of fractional riemann-lioville i...

in this paper, we present a fourth order method for computing simple roots of nonlinear equations by using suitable taylor and weight function approximation. the method is based on weerakoon-fernando method [s. weerakoon, g.i. fernando, a variant of newton's method with third-order convergence, appl. math. lett. 17 (2000) 87-93]. the method is optimal, as it needs three evaluations per ite...

In this paper, we develop a linear optimization model for minimal cost fulfillment of goods in a business to customer (B2C) scenario. In particular, we focus on an Internet enabled retailer (e-tailer) fulfilling the orders received through the Web. We formulate and solve the least cost optimization problem to determine the best choice among the following three options: dedicated fulfillment, ou...
