Abstract
With the increasingly fierce competition in the global shipbuilding industry, shipbuilding enterprises need to maintain competitiveness and cope with rapid changes. In this case, shipbuilding enterprises need to establish effective supply chain management. Among them, choosing the right supplier is one of the most critical activities. The supplier selection of shipbuilding enterprises is considered a complex multicriteria decision-making (MCDM) problem that attracts much attention due to intuitionistic fuzzy sets to deal with possible imprecision and fuzziness in real life. Based on this, this paper proposes a new method based on the intuitionistic fuzzy SWARA (stepwise weight assessment ratio analysis) and COPRAS (complex proportional assessment) method to select shipbuilding enterprise suppliers which is a new research area. First of all, different weights are given to each expert evaluation result according to their position, educational background, and working years. The supplier index’s weight is determined based on the intuitionistic fuzzy SWARA method, and it is easy to understand and operate. The ranking of suppliers is determined by the intuitionistic fuzzy COPRAS method. This method considers all kinds of uncertainties and evaluates the utility index and the cost index of alternative suppliers. Finally, taking a shipbuilding enterprise as an example, applying the intuitionistic fuzzy SWARA-COPRAS method is illustrated. Compared with other methods and sensitivity analysis, it shows that the intuitionistic fuzzy multicriteria decision-making method is effective and stable in shipbuilding enterprises.

In view of the fluctuation of the market economy and the uncertainty of shipowner’s demand, this paper proposes a new intuitionistic fuzzy multicriteria decisionmaking method based on the stepwise weight assessment ratio analysis (SWARA) and COPRAS method
A hybrid method, namely, SWARA and COPRAS, is used to select shipbuilding suppliers. e weight of the supplier index is determined by using the intuitionistic fuzzy SWARA method. e ranking of suppliers is determined by the intuitionistic fuzzy COPRAS method. e method considers all kinds of uncertainties and evaluates the utility and cost indicators of alternative suppliers
Summary
In today’s fiercely competitive environment, shipbuilding companies are facing many challenges. E supplier selection problem of shipbuilding enterprises is an uncertain fuzzy multicriteria decision-making (MCDM) problem. Due to the complexity of shipbuilding enterprise problems, the limitations of decision-makers’ knowledge, the fuzziness of information of alternative suppliers, and the high cost of obtaining the accurate information of shipbuilding enterprises, many criteria decision-making problems are often accompanied by many uncertainties. To solve this problem, fuzzy set and fuzzy logic are introduced to model and describe uncertain information by fuzzy number. (iii) e intuitionistic fuzzy SWARA-COPRAS method is established and applied to a new field: supplier selection of shipbuilding enterprises.
