Supplier Selection of Shipbuilding Enterprises Based on Intuitionistic Fuzzy Multicriteria Decision

Table 1

Comparison of supplier selection methods.

Method	Features
Analytic hierarchy process (AHP)	Simple and practical, qualitative, and quantitative combination, but more indicators easily lead to an increase in the amount of calculation
BP neural network method	Strong nonlinear mapping ability but need a large number of samples and modeling is difficult
Fuzzy set theory and method	The certainty of fuzzy problem is helpful to understand the uncertainty problem and has strong subjectivity
Network analysis method (ANP)	It can reflect the dependence between hierarchies, and it is difficult to understand the relationship between factors
TOPSIS method	Full use of original data, less information loss, strong subjective factors
Mathematical programming (MP) model	Solving single-objective and multiobjective models, more complex
Hybrid methods	Combine a variety of methods to solve, play the advantages of each method
