- 4. The impact of the construction industry on the economic efficiency: In 2012, in the United Kingdom, the construction industry contributed 83 billion Euros to economic output with around 2 million jobs. In 2014, in the United States, this sector contributed 716 billion dollars to the gross domestic product, with around 6 million jobs.

- 5. The construction project management problem comes from practice The project schedules are not always optimal Using optimization methods (i.e. Project resource planning) Introduction and research problem
- 6. Introduction and research problem In construction companies, choosing a finishing strategy to provide resources and raw materials is very important. Contracting companies in the country's construction field may have projects in different parts of the country. If the volume of work or the number of projects in the region increases, it is cost-effective to participate in the preparation and supply of materials.
- 7. Introduction In this study, a new mathematical model is presented. The purpose of this article is to introduce a fractal resource requirement planning (FRRP) model. Assuming three levels of headquarters, regions, and projects as a fractal. This study was carried out in one of the contracting. The finding shows the proposed model could be used in project-oriented construction companies.
- 8. Background of research Warneck (1993) used a fractal method to optimize the supply chain network to increases the speed and reduces the cost of the entire network in manufacturing industries. Liu and Wang (2007) presented a flexible model for resolving linear scheduling problems involving different objectives and resource assignment tasks. Cheng et al. (2013) developed a resource management model using the information constraint net to simulate and optimize resource allocation in the design process.
- 9. Research question Can the fractal model presented in this research be used and implemented for resource management in project-oriented construction companies?

To evaluate the proposed model, it was coded and run by GAMS software and the project information has been used as the input of this mathematical model. Due to the research question, after analyzing and results, it is specified that the proposed model could be used and implemented for resource management in project-oriented construction companies. For future research Discussion & conclusion
