Optimal control problem of variable-order delay system of advertising procedure: Numerical treatment

<p style='text-indent:20px;'>This paper presents an optimal control problem of the general variable-order fractional delay model advertising procedure. The describes flow clients from unaware people group to conscious or bought band. new formulation generalizes that proposed by Muller. Two variables are considered increase number customers who purchased products. An efficient nonstandard difference approach is used study numerically behavior solution mentioned problem. Properties system were introduced analytically and numerically. schema maintains properties analytic solutions as boundedness positivity. Numerical examples, for testing applicability utilized method show simplicity, accuracy efficiency this approximation approach, presented with some comprising standard methods.</p>
