The ongoing transition from traditional plan-based waterfall development models to iterative and software development has created a need for redefinition of software requirements engineering. One of the key driving factors for success in software development is achieving a shared vision of the projects' goals and constraints already early in the process. Having a shared product vision defines the...
The aim of the work is the presentation, critical analysis and the evaluation of contemporary ideas and dilemmas on the basic hypotheses and axioms for consumer behavior modeling. Considerations in the work include the ideas on consumer sovereignty, supposition of consistency and persistency of consumer choice, choice rationality in the conditions of uncertainty and risks, the problems of rational...
In this paper the notion of generalized possibilistic risk premium is introduced as a measure of the risk aversion of an agent faced with several components of possibilistic risk. The main result of the paper is a formula for the calculation of the generalized possibilistic risk premium expressed in terms of a utility function and of some possibilistic indicators.
Lots of risks existed in the process of Emergency Logistics especially when natural disasters happened. Evaluation research on Emergency Logistics Risks (ELR) is the basis of effective early warning and responding to risks, so it's of great theoretical and practical significance to establish an early warning index system for ELR. Firstly, some foundation research about ELR was carried out, including...
Context based recognition system, which can improve the accuracy of scene recognition if robots cannot obtain adequate recognition features in the camera, has attracted researchers recently. However, there are few researches which focus on part-whole supplement system based on context which can describe the scene using detail parts in the scene and also reduce the ambiguity of each detail part using...
Based on Chinese reality, we must continue to promote technological innovation and enterprise culture construction of a common mechanism. Enterprise Culture is a unique cultural management with the core of value, power source of technology innovation. Enterprise Culture provides a power source for technology innovation and it is the foundation to guarantee the performance of enterprise technological...
The main contribution of this paper is to present a new stability criterion of a kind of uncertain systems with time-varying delay. While the system matrices endure segment uncertainty, we show that there is an extreme criterion for the asymptotic stability of the given systems. Such result make it possible to check several vertex conditions. It is proved that, under our assumption, the interval system...
By incorporating intrinsic motivator into the Technology Acceptance Model, this study attempts to explain students' behavioral intention in using the E-learning system from a motivational perspective. In addition, we empirically compared the E-learning system adoption and usage behavior between Chinese students and Canadian students. The results show that both perceived usefulness and enjoyment have...
The paper focused on enterprise and industry level to analyze the resilience of supply chain and point out the resilience analysis thought based on Hooke's law. The analysis result is that the supply chain resilience at industry level is much better than enterprise level. The order of supply chain resilience at enterprise level is: cross expansion type, vertical expansion type, horizontal expansion...
In this paper, the multi-period fuzzy multi-attribute decision making is discussed, where the attribute values are considered as triangular fuzzy variables. A new approach to determine the weights of all periods is proposed. The weighted distance operator and the dynamic weighted distance operator are proposed. A distance method for multi-period fuzzy multi-attribute decision making is presented....
The contribution sketches a possibility how to represent and manage uncertainties in decentralized systems. For this purpose the formal concept of fuzzyness in combination with the formalized language-theoretic concept of grammar systems is used.
Excellent performance model is a systematic management tool to improve quality and performance. This paper focuses on the research of performance measurement and assessment with GB/T 19580 criteria. Aimed at its characteristics of multi-levels and multi-criteria and the uncertainty of information in application, expert fuzzy judgment and a revised ER approach based on D-S theory are applied to measure...
Aiming at threshold uncertainty caused by fuzziness of image for image segmentation, an adaptive thresholding method for gray-level image segmentation using type-II fuzzy sets is proposed . Fuzzy index is got using type-II fuzzy sets technique, that can overcome effectively the uncertainty, histogram peaks value of an image can be find out automatically based on maximum Mahalanobis distance and minimum...
This paper establishes a post-evaluation index system which can be used to economic benefits post-evaluation on the grid construction projects. According to the features of this project evaluation, the membership functions using to evaluate indexes is formed and the value weight is determined by fuzzy AHP .Then, this method is applied to one project with economic effects evaluation. This method can...
With the coming era of intellectual economy, compensation management has become more and more important in business management. How to manage compensation management safely and efficiently has been the focus of attention in modern enterprise. This paper, which starts with risk recognition of compensation management in modern enterprise, analyzes main sources of compensation management risk and offers...
In this paper, the minimal cost spanning tree interval game is studied. It is proved that the interval core is no empty when n=2. By introducing the concepts of the left game, right game of MCSTIG, and compositive, it is proved there exists a hyperplane with non-negative normal vector to separate L and R strictly. when the interval core of MCSTIG is empty. It obtained the sufficient and necessary...
The nonreversibility of strategic investment and nondeterminacy of information acquired from inner and outer environment put importance on the strategic choice timing. Whether the conversion timing is chosen correctly or not has become one of the key factors influencing the conversion performance. At first, this paper analyzes the influencing factors and random characters of strategic choice timing,...
Technological innovation has a vital influence on the development of enterprises. Although the discontinuous technological innovation is the abnormal form, it is the extraordinary important to enterprises. We discuss the discontinuous technological innovation management (DTIM) and analyze the influential factors of DTIM. It is benefit enterprises to improving the DTIM and lowering the risk of discontinuous...
In multi-attribute group decision making, The weights of experts directly affect group decision making. In this paper, from an objective point of view, An adjustment method of experts' weights is proposed on the basis of concrete judgement abilities of experts. Furthermore, a new uncertain multi-attribute group decision method is put forward, Finally, an example verifies its validity.
The purpose of this study was to identify switching costs and examine the moderating effect of switching costs on buyer loyalty model in the B2B e-marketplace. Then a questionnaire was constructed and data were collected from 649 buyers of a Chinese B2B e-marketplace in 114 countries all over the world. Multi-group analysis was applied to examine the moderating effect of switching costs. Finally,...
