Dual-channel supply chain pricing decisions with a risk-averse retailer

Abstract: This paper investigates a dual-channel supply chain with one risk-neutral manufacturer and one risk-averse retailer where there is only one perishable product with price-dependent stochastic demand. We choose Conditional Value-at-Risk criterion to measure the retailer’s risk-averse level, and assume that the manufacturer’s direct sales channel and the retailer’s traditional channel adopt a consistent pricing strategy. The model explores a Nash bargaining problem where the manufacturer and the retailer negotiate with each other on the wholesale price, the retail price and the order quantity when they have equal bargaining power. It is found that when demand uncertainty follows a uniform distribution, a Nash bargaining equilibrium exists and the retail price will decrease as the retailer becomes more risk averse. However, when the risk-averse indicator increases, the manufacturer’s profit on his direct channel will decrease, increase or first increase and then decrease, depending on the values of the relate...

Alternative Ranking-Based Clustering and Reliability Index-Based Consensus Reaching Process for Hesitant Fuzzy Large Scale Group Decision Making

Abstract: Recently, large scale group decision making (LSGDM) problems have become a hotspot. This paper focuses on hesitant fuzzy LSGDM problems where decision makers (DMs) use hesitant fuzzy preference relations (HFPRs) to express their assessment information. HFPRs can represent the fuzziness and hesitancy of DM assessment information well. To improve the efficiency of hesitant fuzzy LSGDM problems, we first propose a reliability index-based consensus reaching process (RI-CRP). By assessing the ordinal consistency of DM's assessment information and measuring the deviation from collective opinion, the DM's opinion reliability index is given. To avoid unreliable information, we propose an unreliable DM management method to be used in the RI-CRP, based on the computation of DM's opinion reliability index. Moreover, an alternative ranking-based clustering (ARC) method with HFPRs is proposed to improve the efficiency of the RI-CRP. The similarity index between two DMs’ opinions is provided to ensure the ARC method can be effectively implemented. Compared with those clustering methods which need to preset several correlated parameters, the presented ARC method is more objective with a different approach based on the alternative ranking. A numerical example shows that the proposed ARC method and the RI-CRP are feasible and effective for hesitant fuzzy LSGDM problems.

The five-factor asset pricing model tests for the Chinese stock market

Abstract: We provide out-of-sample tests of the five-factor model introduced by Fama and French (2015a) for the Chinese stock market. We find strong size, value and profitability patterns in average returns, but weak investment pattern. For portfolios we test, we find that the profitability factor significantly improves the description of average return, however, the investment factor makes marginal contributions. Factor spanning tests prove that the investment factor is redundant during 07/1995–06/2015 and 07/1997–12/2013 for the Chinese stock market. More importantly, the five-factor model passes the GRS tests of Gibbons et al. (1989) for most of portfolios we test.

Building life cycle assessment research: A review by bibliometric analysis

Abstract: This study aims to examine the literature related to the building life cycle assessment (LCA) that are published from 2000 to 2014 by means of bibliometric methods based on databases of the Science Citation Index and Social Science Citation Index. Of 2025 retrieved publications, 95% were journal articles. The patterns of these articles were investigated such as subject categories, journals, countries, institutions, hot topics and the most highly cited articles. The results showed a rapid growth of building LCA related publications with the USA being the leading country in terms of contributing to the largest number of articles and possessing the greatest influence. Norwegian University Science and Technology is the leading university in terms of building LCA research, which is followed by University of California at Berkeley. All the top 15 institutions possess a favorable cooperative relationship with other institutions. Most journal articles were associated with energy (521 articles), followed by material (388), sustainability (304), carbon (299) and technology with 180. According to the comprehensive analysis of the keywords, it can be concluded that subtopics such as energy, materials, environmental impacts and sustainable development will be prominent directions of future building LCA research, while life cycle costing and life cycle inventory will continue to be the common research methods. These findings help to identify hotspots in the building LCA research. Similarly, this study provides useful inputs for the decision making on the subtopic selection and publication strategy in the building LCA research.
