Rough Set Approaches to the Problem of Supplier Selection

The data mining approach of rough set theory is being adopted to study the multi-index question of supplier’s evaluation and determination in order to reveal the determining rules hidden in the historical evaluative data. After introducing some basic notions of rough set theory, this paper uses a sample to tell the steps of the deducing process in detail, and figures out some satisfying rules of supplier’s determination and weights of various attribute’s indexes which have been compared to other methods after the calculation. All of these illustrate the method of rough set theory can be used in the area of supplier’s selection and solve them with great efficiency

The Determination of Chemical Oxygen Demand in Water Quality Analysis

The research is supported by a Project Funded by the brand professional project form Yancheng teachers college (2016) and the teaching reform and practice of medicinal chemistry (2018YCTUJGY006) and the Flagship Major Development of Jiangsu Higher Education Institutions”(PPZY2015B113)。 Abstract Chemical oxygen demand is one of the most important items in water quality analysis. The method is mature and the operation is relatively simple. In this paper, several detailed problems in the determination of chemical oxygen demand (GB11914-89 dichromate method) are presented, and solutions are proposed according to the practical analysis and practice. Keywords Chemical oxygen demand; Determination; Uniformity; Dilution factor; Interference eliminatio

Keywords Permanganate index; Formula of calculation; Parsing; misgiving

Exploring How Blockchain Impacts Loyalty Program Participation Behaviors: An Exploratory Case Study

How to keep customers motivated in participative behaviors remains one major challenge in extant loyalty program (LP) studies. While some companies have initiated efforts to utilize blockchain-based distributed ledgers and smart contract capabilities to enhance customer experience and improve LP efficiencies, academic assessment of blockchain application in the LP context remains scarce. This research attempts to establish a theoretical overview of how the key natures of blockchain influence customers’ varying motivations (economy, autonomy, competence and relatedness) and perceived value, which consequently induce participative behaviors in a loyalty points context. Then, using an exploratory case study of Bubichain in China, we verify that the blockchain-enabled loyalty points scheme not only improves customers’ economic perceived value by meeting their economic motives, as the traditional one does, but also enhances their social interaction and psychological self-fulfillment value perception by meeting their intrinsic motivations, thus increasing customers’ experience and participation behaviors
