The study analyzes the existing supply chain network within a poultry industry and recommended its improvement based on the identified factors while giving more emphasis on the routing and distribution network aspects of supply chain. The recommendation, in the form of optimization model, is verified  and validated using Lingo optimization software. Also, heuristic method is proposed and tested to overcome the complexity of optimization model.
