This project covers supply selection and supply chain management, which includes steps from production to delivery and support. All calculations has been bundled into a web application to make examination useful.

Supply selection is an extensive problem with many variables involved. Comparison between suppliers is crucial and needs to be performed with utmost delicacy. In order to perform this comparison one can compare two criterias in each step. AHP is one of the methods which can perform comparison with many criterias involved, can be used to help compare suppliers with many criterias. In this project AHP is used to compare such suppliers with the help of the real world variables obtained from real world institutions. Using this real world data a Python application has been written to simulate comparision between suppliers with many criterias.
