Present worth (PW) analysis is an important technique in engineering economics for investment analysis. The values of PW parameters such as interest rate, first cost, salvage value and annual cash flow are generally estimated including some degree uncertainty. In order to capture the vagueness these parameters, fuzzy sets often used literature. this study, we introduce interval-valued intuition...

Neutrosophic theory has many applications in graph theory, interval valued neutrosophic graph (IVNG) is the generalization of fuzzy graph, intuitionistic fuzzy graph and single valued neutrosophic graph. In this paper, we introduced some types of IVNGs, which are subdivision IVNGs, middle IVNGs, total IVNGs and interval valued neutrosophic line graphs (IVNLGs), also discussed the isomorphism, c...

The aim of this paper is to investigate the multiple attribute decision making problems to deal with the supplier selection in supply chain management with interval-valued intuitionistic fuzzy information. Based on the traditional project method, calculation steps for solving interval-valued intuitionistic fuzzy multiple attribute decision-making problems with known weight information are given...
