Nowadays in the markets competitive atmosphere, the companies aren’t able to provide their needs. So they prefer to use supply chain. Selecting the suppliers is introduced as a multi attribute decision making (MADM) problem. The current paper tries to solve this problem based on three parameter interval grey numbers. So, within use of AHP-Bull’s eye integration weighting method, this paper wants to weigh attributes and ranks alternatives by PAF (Projection Attribute Function) method. at the end, in order to show the ability of this method, the robustness of this method is tested in front of SAW method (that is one of the celebrated method).

Due to considering the real conditions of project and solving manager’s problems, the primary methods development of scheduling for projects has recently drawn researcher’s attentions so that these methods are looking for finding optimal sequence to realize project goals and to provide its constraints such as dependence, resource constraint (renewable and non-renewable).
The importance of these issues has practically and theoretically led researchers to do much efforts on different conditions of issues for project schedule, various methods to solve and or to develop each of them.
In this research based on selection of some executive methods for any activity with renewable and non-renewable resource and considering prerequisite relation from kind of start to end and having delivery time for any activity in two time periods that has been provided with regard to delivery time of penalty cost with delay or without delay.
The presented model has been solved in small scale by gams software and in small, medium and large scale using meta-heuristic Methods of NSGA ll and cuckoo after coding in software of matlab 2013. The comparison of the answer obtained from the above algorithm indicates the better performance of genetic algorithm in most indexes and cuckoo algorithm has superiority on time index of problem solving.
