Variable Precision Rough Set (VPRS) model is one of the most important extensions of the Classical Rough Set (RS) theory. It employs a majority inclusion relation mechanism in order to make the Classical RS model become more fault tolerant, and therefore the generalization of the model is improved. This paper can be viewed as an extension of previous investigations on attribution reduction problem...
A evolutionary identification algorithm RLS-PSO is introduced to the Hammerstein system, the details of calculation are shown. A numerical example is proposed to show the rationality and effectiveness of this algorithm. The convergence performance is also analyzed in this paper, it is proved that the algorithm can converge with a large N.
Influence of electron beam misalignment and emission inhomogeneity on gyrotron operation regimewas studied. A comparison of experimental results, numerical simulation data based on multimode nonstationary models of beam-wave interaction in a cavity gyrotron and 3d simulation was made.
Today's service systems are growing more complex and dynamic due to the coupling of functionalities required under different contexts, which asks for extra effort from both service users and services developers. An ideal service system shall provide just right functionalities and just enough qualities to its user under a given usage context. Moreover, the service shall adapt itself when requirements...
According to the data feature of customer's consumption records of bank POS machine and the analysis depending on the actual requirements, a new modeling framework on consumption behavior of bank POS machines is presented in this paper, and further research on the implementation method of main aspects in the model is carried out. Firstly, we conduct data discretization and customer segmentation by...
The research on the business models is a hot topic in recent years. It is an interesting problem to study the business model of the service. There are three kinds of models related: classical service models, Business process (BP) models and the enterprise business (EB) models in management. However, none of them covers all the properties of the service business model. In this paper, we define the...
With the development of the Internet, online shopping has become a symbol of the times. The delivery, as the most critical part is also developed rapidly. The study of the relationship between online shops, express delivery and customer satisfaction has become a hot topic. This article analyzed the impact of online shops and express service quality from the perspective of customer satisfaction, taking...
With the increasingly serious situation of global warming, governments all over the world have adopted various carbon emission policies to strengthen the carbon regulation to enterprises and supply chains. This paper builds a supply chain (two-echelon supply chain, one producer and one retailer) carbon emissions model based on the theory of System Dynamics. We introduce the carbon emission polices...
This article considers extended warranty decisions in competing dual-channel supply chains and uses game theories to analyze three model. We also discuss scenarios when the manufacturer provides the extended warranty and when the retailer does in each model. Our analysis reveals that: 1) In model MR, scenario MR-R outperforms MR-M for the manufacturer, the retailer and the whole system. 2) In model...
Gift cards are widely used by many enterprises nowadays for products promotion. Gift cards are used not only for a basket of goods, but also for some specific kinds of goods. In this paper, we characterize consumers' purchasing behavior according to descending consumers' reservation price, then develop a model to derive the optimal purchase amount threshold and gift card value. We find that offering...
We consider a dual channel supply chain in which a manufacturer sells a single product to end-users through a traditional retail channel and a manufacturer-owned direct online channel. This paper analyzes the profits and the demands of the manufacturer and retailer in three service policies of the retailer using Stackelberg game. Combined with the numerical example, the results show that: The profits...
Terminal iterative learning control (TILC) has been developed to track a single desired point at the terminal end of operation interval over iterations. In this paper, the feedback control knowledge of previous time instants is utilized via an equivalent dynamical predictive model to update the input signals for the TILC problem. The proposed scheme consists of a control input updating law with feedback...
This paper is a study of staff issues at the bank, ICBC China. Due to extra and imbalanced staff, the system was idle most of the time. By using the qualitative approach, M/M/s queuing model and discrete event simulation, the staff was sub-optimized. First, observation of the system was conducted and recorded using the existing operations system used by the bank. Arrival time of customers, service...
Knowledge transfer is an important type of knowledge service. Based on existing studies on knowledge transfer between employees, this paper builds a research model of factors affecting the pre-retiree's intention to transfer knowledge to the younger employee. Data collected from 4 leaders and 7 pre-retirees in different industries through face-to-face interview is used to test and improve the model,...
This paper investigated the influence of suppliers' profits who manufacture the alternative commodities and the consumer utility, in the situations that the suppliers choose the common or the excusive shop to sell their commodities. By comparing suppliers' profits and consumer utility, the analysis suggested such a conclusion: in general, suppliers' profits and consumer utility in the exclusive shop...
Based on the result in literature[5], the paper focuses on exploring enterprise optimal production problem, considering emission permits and trading, restricted by Government subsidies and punishment policy. We build the corresponding model considering such condition, and compute its optimal solution, then investigate the relationship between optimal output and enterprise optimal revenue in the model,...
In hydrogeology, estimating aquifer permeability is an important issue. This can be useful in understanding the flow of pollutants from one area of an aquifer to another. For this aquifer analysis sake, the Hydrogeological Experimental Site of Poitiers (France) covering a limestone aquifer is an appropriate instrumented test bed enabling measurement of hydraulic responses of a series of observation...
We extend the expectation-based loss-averse newsvendor model according [1] by assuming that decision maker confronts deterministic demand and uncertain supply at the beginning of a selling season. We show with numerical study that the higher the penalty coefficient, the lower the optimal order quantity. Higher retail price and salvage value lead to optimally order more. However, when the wholesale...
Instructional activities should allow applying the knowledge acquired in the day by day and in real situations. Different studies evidence the potential impact of video games on learning, however very few empirical studies that focus on continuous assessment. On the other hand, because the variables that influence the achievement of learning objectives are different levels becomes complex to validation...
This paper builds a simple model to analyze advertisement on a digital map. In our model consumers search for a specific firm but might be lured to nearby firms. A map owner charges a lump sum fee and controls entry. We show that the map owner has incentive to manipulate the quality of firms on the map according to the level of consumers' switching propensity and advertisement aversion. Strong switching...
