A multiple criteria decision analysis (MCDA) problem is studied in this paper, for which the evaluation results obey a particular distribution. First, when solving a multiple criteria decision analysis (MCDA) problem, a grey target decision analysis framework is proposed to determine uncertain parameters and criteria weights. A measurement for comprehensive off-target distance is defined, which includes the undetermined parameters. Second, to satisfy the requirements of a specific distribution (such as a normal distribution) in the assessment results, an optimization model that incorporates the off-target distance constraints is proposed by considering the skewness and kurtosis test method. Third, a particle swarm optimization (PSO) algorithm is extended to solve the proposed model by seeking the appropriate parameters and weights. Fourth, a numerical example is applied to demonstrate the feasibility and application of the proposed method. In the end, the proposed model is extended to other distribution requirements.
This paper analyses the strategies of the substitutable suppliers competing to collaborate with a main manufacturer in “main manufacturer–supplier” (M-S) mode. In the research and development (R&D) of complex products, only one supplier can be chosen for one kind of part as a long-term collaboration partner with the manufacturer. The competition between substitutable suppliers focuses on the technology docking and price-concluding strategies. In this paper, one original supplier as the first-mover and one new supplier as the second-mover chose between the two strategies sequentially to compete for the collaborative preference of the manufacturer. We also took the delay cost brought by strategy changing into the consideration of the risks, which the suppliers and the manufacturer should prepare to share. With evolutionary game theory applied, we can conclude that the initial costs have little impact on suppliers’ making decisions, while the initial prices are correlated with both suppliers’ decision making. Results also show that hesitation and fluctuation periods exist in suppliers’ decision making, which have a relationship with existing strategy conditions, initial prices, and the cost caused by modifying the part. These results provide practical and reasonable managerial implications for M-S collaboration.
This paper analyzed the effects of the problem size and the problem proposing mechanism on the decision-making processes, for the manufacturer and the supplier, regarding processing a problem in a new main manufacturer–supplier collaborative system using evolutionary game theory. Unpredicted problems may arise in the process of collaborative research and development (R&D) of complex products, like big passenger aircrafts, without any relative advanced contract, and either player will take risks to announce it. In addition to the factors of traditional cost and income, we take another two factors (i.e., the problem size and the problem proposing mechanism) into account in the examination of the problem processing mechanism. With evolutionary game theory applied, we can obtain the stable decision-making states of both players and how these two factors affect the problem processing mechanism. From the result, we find that the problem size has little effect on the two players’ decisions, while the problem processing mechanism has an impact when the experiences or the capacities of the manufacturer and the supplier are unbalanced. This paper contributes to manufacturer and supplier in a newly-established collaborative system to consider how to behave when unpredicted problems come.

To deal with emergencies in the development of large passenger aircraft, the optimization of supply chain resilience is studied. First, based on the “main manufacturer–supplier” model adopted by the synergistic development supply chain of large passenger aircraft, a resilience analysis framework is established from the perspective of the main manufacturer and supplier, based on which a bilateral grey quality function deployment resilience measurement model is proposed. Second, a single-perspective resilience optimization model of the main manufacturer and supplier under cost constraints is constructed. Then, an overall resilience optimization model of the supply chain considering the synergistic effect and cooperation uncertainty is presented. Finally, the development of a large airliner’s fuselage is taken as an example to illustrate the feasibility and validity of the proposed model. The results show that (1) the synergy between the main manufacturers and suppliers can not only improve resilience of the whole supply chain, but also reduce their own competitiveness and resilience, respectively; (2) a benign cooperative relationship can effectively improve the overall resilience; on the contrary, it can reduce the overall elasticity; (3) the cost of supply chain has a great impact on the resilience of the main manufacturers and suppliers, respectively.
