Shortest path problem (SPP) is an important and well-known combinatorial optimization problem in graph theory. Uncertainty exists almost in every real-life application of SPP. The neutrosophic set is one of the popular tools to represent and handle uncertainty in information due to imprecise, incomplete, inconsistent, and indeterminate circumstances. This chapter introduces a mathematical model of SPP in neutrosophic environment. This problem is called as neutrosophic shortest path problem (NSPP). The utility of neutrosophic set as arc lengths and its real-life applications are described in this chapter. Further, the chapter also includes the different operators to handle multi-criteria decision-making problem. This chapter describes three different approaches for solving the neutrosophic shortest path problem. Finally, the numerical examples are illustrated to understand the above discussed algorithms.

1. Introduction

Neutrosophic sets (NS) theory is proposed by Smarandache [ (1999); (2005)], and this is generalised from the intuitionistic fuzzy set (Atanassov K. T., 1986) and fuzzy set (Zadeh, 1965). NS deals with indeterminate, uncertain and incongruous data where the indeterminacy is calculated explicitly. Moreover, indeterminacy, falsity and truth membership are fully independent. It overcomes some restrictions of the current methods in portraying uncertain decision. Samarandche’s contribution towards neutrosophic theory is summarized in Table 1.
