The purpose of this study is to explore factors influencing Indonesian consumers to brand loyalty and customer repurchase intention of Korean beauty products. This study uses a quantitative approach to test the hypotheses. A sample of 411 respondents was collected by online questionnaires in Indonesia. Causal research design and SEM analysis are also conducted to determine the relationship between constructs. The finding showed that brand name, product quality, product design, promotion and brand loyalty have significant influence on repurchase intention. Moreover, all of product characteristics (brand name, product quality, product design and promotion) also have a significant influence on brand loyalty. This study explains some practical directions for beauty product companies to do better marketing strategies. Beauty product enterprises should give priorities to brand name, product quality, product design and promotion as the basic factor influencing consumers to repurchase the product. On the other hand, a commitment to build a strong brand loyalty in consumers' mind is a compulsory. Once consumers are loyal to one brand, they will keep buying a same product from a same brand again and again.

Massively multiplayer online games (MMOG) have becoming increasingly popular in recent years, but the problem of low player stickiness has always existed. Meanwhile, little is known about what motivates players to generate such stickiness. This paper built a research model based on the attitude, perceived enjoyment, aesthetic design, telepresence, team participation and network externalities to identify the antecedents of player stickiness in the context of MMOG. Structural equation modeling (SEM) is employed for data analysis. Analysis of 265 valid responses to a survey questionnaire indicate that attitude, a medium factor, has great positive effect on stickiness. Among the antecedents of attitude, perceived enjoyment is found to have the strongest effect. In addition, team participation, weak-link influence and strong-link influence have a positive correlation with attitude. But aesthetic design and telepresence have no significant influence on attitude. Also, implications are discussed in the paper.

Nowadays, as a new commercial format, cross-border e-commerce has rapidly developed with China's policy support and consumption upgrade. With the advantages of “Belt and Road” strategy, China's cross-border e-commerce industry will confront more opportunities, while facing more fierce competition. Under this background, how to increase usage frequency as well as repurchase intention of customers, has become a significant and emergent problem for Chinese cross-border e-commerce platform companies. This paper defines the dimension of platform quality from the perspective of customer perception, which mainly focuses on the three aspects: system quality, information quality and service quality. Based on the theory of Stimulate-Organism-Response theory, this research takes cross-border e-commerce platform quality as independent variable, customer trust as the mediating variable and cross-buying intention as dependent variable. This paper also divides cross-buying intentions into three types, including point cross-buying intention, line cross-buying intention, and plane cross-buying intention. The authors conduct a survey in the form of questionnaire and the research model is tested by a sample of 235 online customers. The empirical results show that: (1)The three dimensions of platform quality all have positive effect on customer trust. (2) System quality and service quality have direct and positive effect on cross-buying intention. (3)Customer trust have positive effect on the cross-buying intention.(4)Customer trust has mediating effect between the three dimensions of platform quality and cross-buying intention.

Along with the rapid development of electronic commerce, the importance of logistics links and new designs of automated warehouse have been developed. A big boost has been given by shuttle-based storage and retrieval system (SBS/RS). Compared with traditional mini-load automated storage and retrieval system, SBS/RS could achieve higher warehouses volume and throughput capacity. Since in each tier there is a single shuttle in most SBS/RS, lift is always the bottleneck of this system. While all of the previous papers use lower left-point input/output location, in this paper, we present a single and dual command cycle time model of the elevator lifting table of the SBS/RS with middle I/O point location and consider the motion characteristics of the lift. The numerical analysis considers three different rack configurations and four velocity profiles. The results demonstrate good performance of our model, the dual command cycle time of lift reduce by 28.3% under the condition of middle I/O point, and the throughout increase by 17.3%.

Membership tier is an important measure for enterprises to implement customer loyalty programs in big data environment. The differences in online review behavior of different tiers of users directly affect the interaction between the company and the customer. This paper uses online review behavior data in the real membership tier to explore the differences in online review behavior from the perspective of membership tiers. This study find that customer membership tier is positively correlated with the review rating score, and membership tier is not significantly correlated with the length of the review. Membership tier is positively correlated with the ratio of review sentiment words, and negatively correlated with the objective description words, showing a significant difference between behavioral loyalty and attitude loyalty.

According to two situations of establishing the threshold of social reputation of the online lending platform, this paper establishes the profit maximization model of P2P lending platform, analyzing the pricing of P2P lending platform and answering whether and when it is necessary to establish a social reputation threshold for borrowers. Moreover, this paper analyzes the influence of the platform's exclusive strategy on the number of bilateral users and the platform's profit. The results show that the platform needs to set the threshold when lenders are more sensitive to borrowers' social reputation. In addition, through the analysis of market size and platform profit, it is found that when the platform strengthens the sensitivity of lenders to the average social credit level of borrowers, it will increase the number of lenders and the platform's own profit at the same time.

To solve these pricing and channeling issues, we consider a dual-channel supply chain consisting of the manufacturer producing new and remanufactured products simultaneously, the independent retailer selling new products, and the manufacturer selling remanufactured products, then investigates optimal pricing strategies for the new and remanufactured products between the centralized and decentralized decision-making models by applying optimization and game theory. By comparing the two models we find that the optimal prices of the new and remanufactured products not only depend on the government's subsidy level of remanufacturing, but also relate to the unit cost saving of producing remanufactured products with respect to new products and the decision-making methods in the dual-channel supply chain. Meanwhile, it is found that there is also a “double marginalization” in the decentralized situation, thus we coordinate the dual-channel supply chain using a two-part tariff contract. Specifically, only the manufacturer adjusts dynamically the wholesale price and fixed fee within the coordinating contract according to the government's subsidy level of remanufacturing. Finally, we obtain several interesting conclusions from the numerical examples and provide managerial insights and policy implications from the analytical results. In particular, our finding of the economic, social, and environmental benefits of remanufacturing operations managed by the dual-channel supply chain has implications for both academics and managers.

Multitasking scheduling is essential for decision making in many academic disciplines, including operations management, computer science, and information systems. In multitasking settings, each waiting job interrupts the currently in-processing job, causing an interruption time and switching time. It is difficult to make production planning under the multitasking settings, especially when considering uncertainty. However, most existing works about the problem focus on the deterministic environment, which is unpractical in actual life. In this paper, we investigate a multitasking scheduling problem on parallel machines. Moreover, uncertain processing times, which may be caused by multi-skilled workers, different machines and so on, are taken into account. The objective is to minimize the weighted sum of the earliness and tardiness. A two-stage stochastic programming formulation based on scenarios is developed. The first stage is to determine the operating machine for each job, and the processing sequence of jobs is made in the second stage. Sample average approximation (SAA) is adopted to solve the model. Finally, computational experiments are conducted and we give the impacts by sensitivity analyses.
