Hazards in different areas have different effects and consequences. Nowadays considering industries vital conditions, it seems necessary to boost organizations confronting uncertainties and risks. One solution for reducing these risks, is increasing agility, stability and flexibility in production process. This study tries to increase organization capabilities in supply chain hazards handing, using integration of production and transportation planning, shared transportation navigation and Multi-site manufacturing to minimize total tardiness in supplying required raw material and parts for a manufacturer. Considering that it is a NP-hard problem it is not possible to solve it in a reasonable time using exact methods. Hence, a genetic algorithm named dynamic genetic algorithm (DGA) is proposed to solve it. After that, results in single-site and multi-site problems are compared. The results show that multi-site manufacturing caused less tardiness than single-site manufacturing in reality. Also, increasing the number of suppliers, the number of vehicles and reducing the number of orders, the value of process times and transportation times causes tardiness reduction in a supply chain.
