Resource leveling schedule is important for construction planning process very much because quantity of resource such as labors is limited. The optimal solution to allocate enough resource for every activity is main principle for project successful. But in ordinary they always observe that have different quantity of resource every time periods is called of “Resource fluctuation”. So planners have to adjust first schedule is called of “Resource Leveling”. This method necessary for decrease resource fluctuations or make uniformly resource demand level . However normal method (heuristic method) to solve this problem is difficult and use much time. So in present there is new developed method by create model in spreadsheet computer programs such as Microsoft Excel. This new method can solve very complex resource leveling problem well..So in this research if we add vary relationship options such as SS (Start-To-Start) FF (Finish-To- Finish) or NO (No Relation) for activity in model objective is increasing optimal solution flexibly and output solution is better than El Rayes & Jun ‘s Model. We can discover for optimal solution from this new model that received uniformly resource demand level of project schedule in the end
