Abstract
Project delivery system selection is an essential part of project management. In the process of choosing appropriate transaction model, many factors should be under consideration, such as the capability and experience of proprietors, project implementation risk, and so on. How to make their comprehensive evaluations and select the optimal delivery system? This paper proposes a decision-making approach based on an extended linguistic preference structure: simplified neutrosophic linguistic preference relations (SNLPRs). The basic elements in SNLPRs are simplified neutrosophic linguistic numbers (SNLNs). First, several distance measures of SNLNs are introduced. A distance-based consistency index is provided to measure the consistency degree of a simplified neutrosophic linguistic preference relation (SNLPR). When the SNLPR is not acceptably consistent, a consistency-improving automatic iterative algorithm may be used. Afterwards, a decision-making method with SNLPRs is developed. The example of its application in project delivery systems’ selection is offered, and a comparison analysis is given in the end as well.

Summary
Construction is a carrier of fixed asset investment in a country, and a channel to adjust products and industrial structures [1,2]. A few scientific and rational decision-making methods related to the selection of project delivery systems have been established. Constructed a project delivery system model based on fuzzy sets. The decision-making methods based on a judgment matrix (preference relations) with NSs or other extensions may be valuable and necessary. On the basis of linguistic term sets and simplified neutrosophic numbers [59], simplified neutrosophic linguistic numbers (SNLNs) may be one of the most widely used extensions [60,61,62] The former stands for the qualitative evaluation values of project systems [63,64,65], and the latter are the truth-membership, indeterminacy-membership, and false-membership of the qualitative assessment. This paper studies a decision-making method with preference relations under simplified neutrosophic linguistic environment.
