Supply chains are becoming more vulnerable because of harsher and more frequent natural and man-made disasters. Supply chain disruptions now seem to occur more frequently and with more serious consequences. During and after supply chain disruptions, companies may lose revenue and incur high recovery costs. Therefore, if supply chain managers were able to better measure and manage supply chain vulnerability,...
One of the most popular techniques to handle insecurities and risks in project management is the well-known PERT approach. But this approach contains some disadvantages that are not always clearly visible at first sight. In this contribution we show how to overcome these disadvantages of the PERT approach by using Monte Carlo simulation.
Most of questions have the uncertainty and the illegibility. Taking account of the insufficiency of two value logic neuron, the paper puts forward three-valued logic neural network, based on the multiple correlation analysis, which have been successfully used in the bank risk assessment. The paper, firstly has constructed the multiple correlation model. Secondly, puts forward the three-valued logic...
The research proposes a new method of assessing performance risk and uncertainty with high confidence for a linear-quadratic class of stochastic pursuit-evasion on the basis of multi-player confrontations and competitions. The proposed method to characterize higher-order performance uncertainties for this class of differential games is enabled by three prerequisites: 1) the Know-How related to competence;...
Risk assessment (RA) can be considered to be a sub-system of risk management (RM). Some socioeconomic aspects of creating uncertainty in a residential development in a South African case study are discussed within a systems context. The cultural dimension creating uncertainty in the residential development undertaken by a Chinese company in South Africa is also explored. Conceptual risk simulation...
This paper examines that the investors do not ignore but overestimate the earnings persistence, which rejects the earnings persistence hypothesis for the post earnings-announcement drift. Investors have more concerns about the past accounting information than the current accounting information probably because of the conservatism in the information uncertainty. Investors are not able to distinguish...
Enterprise risk conduction is the course that a little beginning departure or uncertainty has been transferred to process of operation, because of disturbance of interior and exterior uncertain factors in enterprise. The article firstly establish multi-dimensional characteristics matter-element matrix about subject which can describe the quantitative process of enterprise risk conduction, then discusses...
Recommendation-based trust models have emerged as an important risk management mechanism in E-commerce and online environments. This paper presents a trust model with trust derivation and transitivity based on subjective logic and the theory of collaborative filtering. For dealing with trust derivations, the theory of subjective logic is used to translate similarity taken from Collaborative Filtering(CF)...
B2C e-commerce brings many advantages for online consumers. Meanwhile online consumers face much more uncertainty in B2C e-commerce. Customers' perception has direct effect on customers' online initial trust and purchasing intention. Furthermore, customers' perception affects consumer's acceptance of B2C e-commerce.
