Increasing the dynamics of the conditions governing economic and financial activities and increasing the risk of decision-making in the field of investment or financing of investment projects and economic projects requires the existence of an appropriate and efficient analytical method that does not have the shortcomings of conventional methods of discounting cash flows, including stagnation. Accordingly, and in response to new needs, the real option of assignment with a binomial tree approach in the DERIVAGEM software has been used for decision-making. For pricing using this method, input parameters are required. For the asset price parameter, the present value of the plan is considered, and for the exercise price parameter (agreed price), the present value of the cost is considered. Finally, the conventional method and the real option method are compared. The pricing results show that the value of the option to abandon is 1,273,845 million rials, which is the value of the project, or in other words, the value of the developed project, is estimated at 1,229,258 million rials, which is higher than the conventional method. The appropriate times for the relevant project Abandonment are at nodes (4,5) and (5,6). Based on sensitivity analyses, the strongest variable affecting the project value at the disposal of the release is the fluctuation of the asset value.
