Decision making with the generalized intuitionistic fuzzy power interaction averaging operators

Abstract: Considering the interactions between different intuitionistic fuzzy sets, this paper extends the power averaging operators to intuitionistic fuzzy environments and develops some intuitionistic fuzzy power interaction aggregation operators, including the generalized intuitionistic fuzzy power interaction averaging operator, the weighted generalized intuitionistic fuzzy power interaction averaging operator and the generalized intuitionistic fuzzy power ordered weighted interaction averaging operator. The properties of these aggregation operators are investigated. The key advantages of these operators are that they not only accommodate situations in which the input arguments are intuitionistic fuzzy numbers (IFNs) and take the interactions of different IFNs into consideration, but also consider the decision situations that the relationships between the IFNs are fused. Moreover, we apply the new proposed aggregation operators to multiple attributes decision making and examples are illustrated to show the validity and feasibility of the new approaches.

Key Factors of Project Characteristics Affecting Project Delivery System Decision Making in the Chinese Construction Industry: Case Study Using Chinese Data Based on Rough Set Theory

Abstract: A project delivery system (PDS), as one of the crucial factors of project success, not only influences innovation in the construction industry but also strongly affects project schedules, costs, and quality. Traditionally, decision making concerning PDSs have often been made by owners or other decision makers on the basis of these individuals’ experiences, which often fail to reflect the inherent laws and dependencies among various factors and different PDSs. Recent studies on PDS selection have primarily focused on owners’ characteristics, project characteristics, and external environment. This study was first conducted exclusively on the project characteristics as the continuation of research on owners’ and contractors’ characteristics. First, 16 project characteristic factors affecting the PDS selection were described through a literature review. Next, project characteristics data from 101 domestic projects were collected using a questionnaire survey to determine the key factors that affect the...

Merger strategies in a supply chain with asymmetric capital-constrained retailers upon market power dependent trade credit

Abstract: Merger and acquisition activities, which are increasing in both deal volume and value, are believed to be profitable. However, a merger is not always the best option. To investigate participants’ preferences regarding merger strategies, we consider a supply chain consisting of one supplier and two asymmetric capital-constrained retailers; in this chain, the supplier and two retailers vertically interact in a Stackelberg game, while the two retailers compete horizontally in a Cournot game. Through investigating the impacts of merger effects and the retailers’ market power on each player's optimal decision and post-merger supply chain performance, we find that when merger effects perform well, the supplier prefers that the two retailers merge horizontally if their market power does not vary significantly, while it would prefer to merge with the large retailer if the market power of the two retailers varies greatly. Conversely, when merger effects perform poorly, the supplier prefers that all players maintain their independence. Moreover, the larger retailer will seek a horizontal merger when merger effects perform well, and will prefer to merge with the small retailer in the occasion of poor merger effects and balanced market power. However, if the large retailer possesses significantly more market power than the smaller retailer, the most beneficial outcome is that all members operate independently. Furthermore, a horizontal merger benefits the small retailer most. Surprisingly, we find a Pareto zone that produces a multi-win result when all players prefer a horizontal merger.
