摘要：Empowering the value realization of ecological products with a digital economy is an important path for achieving the transformation of“two mountains”and the construction of ecological *** on the panel data of 30 provinces in China from 2011 to 2022,a fixed-effects model was used to empirically test the impact,heterogeneity and mechanism of the effects of the digital economy on the value realization of ecological *** analysis revealed three key findings.(1)The digital economy has a significant driving effect on improving the ability to realize the value of ecological products,and this effect is still applicable in a variety of robustness tests such as shrinking the years,replacing explanatory variables,and endogeneity tests.(2)The rise of the digital economy affects the value realization of ecological products to different degrees in different regions,especially in the eastern region,while the effect in the central region is not obvious.(3)The analysis of mechanistic variables indicated that the digital economy has an impact on the value realization of ecological products through the development of green finance and government ***,the government should design differentiated and multi-level support policies for the realization of ecological product value according to the heterogeneity of natural resources,ecological potential and the levels of digital economy development in different regions,and it should strengthen the control of non-environmental protection behaviors of the *** should accelerate the digital transformation of the entire production,distribution,circulation and consumption chain of ecological products,and actively develop financial products and services that meet the characteristics and needs of ecological products.

摘要：To study the effect of cooperative advertising on the supply chain of deteriorating items, this paper establishes a Stackelberg game model for a two-echelon deteriorating items supply chain composed of one manufacturer and one retailer under a given support program with an exogenous participation rate. The manufacturer as the leader determines the wholesale price and production rate, and the retailer as the follower determines the retail price and advertising strategies. The strategies of the players under the decentralized scenario and the centralized scenario are respectively characterized. Numerical simulations and sensitivity analysis are conducted to gain some managerial insights. It is shown that the pricing, advertising and production strategies are negatively correlated to deteriorating coefficient, and both the profit and the channel efficiency decrease with deteriorating coefficient; The interaction between price, advertising investment and production rate results in a higher retail price of the centralized channel compared to that of the decentralized channel; Implementing the cooperative advertising program does improve the performance of the supply chain in some cases and the participation rate roughly at 0.5 is most preferable, but it is also possible to distort incentive and damage the channel performance when the participation rate reaches a relatively high level.

摘要：Minimizing the impact of the mixed uncertainties(i.e.,the aleatory uncertainty and the epistemic uncertainty) for a complex product of compliant mechanism(CPCM) quality improvement signifies a fascinating research topic to enhance the ***, most of the existing works in the CPCM robust design optimization neglect the mixed uncertainties, which might result in an unstable design or even an infeasible design. To solve this issue, a response surface methodology-based hybrid robust design optimization(RSM-based HRDO) approach is proposed to improve the robustness of the quality characteristic for the CPCM via considering the mixed uncertainties in the robust design optimization. A bridge-type amplification mechanism is used to manifest the effectiveness of the proposed approach. The comparison results prove that the proposed approach can not only keep its superiority in the robustness, but also provide a robust scheme for optimizing the design parameters.

摘要：The government subsidy plays an important role in the recycling and remanufacturing process of a closed-loop supply *** paper focuses on the impacts of different patterns of government subsidy on the chain members'profits and the ***,we develop three models in a supply chain including a manufacturer,a retailer and a collector,namely(1)the government invests public service advertisement to stimulate the remanufacturing process(Model AS);(2)the government offers only monetary subsidy to the collector(Model MS);(3)the government allocates the subsidy into two parts,namely both advertisement and monetary subsidy(Model HS).We find that,no matter which subsidy pattern the government adopts,both the manufacturer and the collector are beneficiaries of the government subsidy,and that such subsidizing activity is definitely conducive to the environmental *** into account the chain members,profits and the environmental impact,the optimal hybrid subsidy scheme(Model HS)is more beneficial than that in both Model MS and Model AS,which can be attributed to the combination of the incentives provided by the public service advertisement and the price attraction by the monetary *** also find that,for single advertisement and monetary subsidy,the amount of government subsidy will decide their merits and *** direct monetary subsidy in Model MS will have a greater influence regarding to the supply quantity of used products than the mere advertisement subsidy in Model AS when the subsidy is relatively large.

摘要：Industrial development can enrich people＇s lives, but it also causes environmental pollution, which is an area of significant concern among governments, consumers, and companies. Governments formulate some environmental policies, which motivate industry by providing greater incentives for green product development. Consumers are classified into two groups - ordinary and green market segments - according to their environmental awareness and attitudes. In this regard, companies need to reconsider their primary product design strategies. By investigating the interactions among customers＇ preferences, firms＇ product strategies, and government subsidy policies, this paper presents a theoretical model for new product design strategies. After detailed theoretical analysis of such strategies, we found that to motivate firms to choose environmentally friendly product design strategies, governments should inaugurate effective subsidy policies. After simultaneously considering environmental issues and firms＇ benefits, we designed a subsidy policy. With such a policy, firms can change their primary product design strategies and develop both green and ordinary products, thereby increasing the firms＇ profits and improving the total environmental quality.

摘要：For the gray attributes of the equipment program and its difficulty to carry out the quantitative assessment of the equipment program information, the gray relation projection method is simply reviewed. Combining the super-data envelopment analysis（DEA） model and the gray system theory, a new super-DEA for measuring the weight is proposed, and a gray relation projection model is established to rank the equipment programs. Finally, this approach is used to evaluate the equipment program. The results are verified valid and can provide a new way for evaluating the equipment program.

摘要：Product customization has been recognized as an effective means to implement mass cus-tomization （MC）. A new theory and method for MC-oriented evolutionary design of configuration product is presented based on the study of developing law of evolutionary design in integrated envi-ronment, which focuses on the innovation and reuse properties of configuration product. The key technologies for general requirement modeling in quick response to customer requirement, multi-level stepwise configuration optimization driven by customer requirement and evolutionary deduction of product variable structure based on configuration association are thoroughly investigated. The suc-cessful application of the presented method in the development of real-life products demonstrates its utility, flexibility and robusticity.
