The main formal tasks of the information security risk management process using functional and contextual models reflecting the basic concepts and basic functions of information security risk management systems.
Issues of development of mathematical models and the software of Information System of Bankruptcy Risk Management of an enterprise (ISBRM) are considered in the paper. ISBRM implements a multilevel approach to bankruptcy risk management of an enterprise, based on three main phases: the identification of risk factors, the assessment of factors and bankruptcy risk level, the choice of risk minimization...
With the increasingly security problems in networks and systems, the evolution of development models that underlie current tools and techniques is all that is required to produce a model of self-defense where all the components are self-protected. The great extension of current models recommends a reasonable transition fundamentally based on the family of standards ISO/IEC 31000, where the selection...
This article discusses the status and problem of risk management technology in domestic commercial bank, and analyze the gap of risk management technology application in commercial banks at home and abroad, and put forward to build the infrastructure of comprehensive risk management system within commercial bank. This article also introduce a project named "Financial Risk Control in the Quantitative...
High risk and high profit are the remarkable characters of enterprise technological innovation. The higher innovation degree is, the higher uncertainty will be. It is very important to analyze entirely all kinds of risk factors which can influence technological innovation and evaluate the process of technological innovation. In this paper, based on the index system of enterprise technological innovation,...
The paper makes analysis of the investment risks towards new power shares in Chinese stock markets based on Markowitz mean-variance model using Monte Carlo simulation for solution. Five stocks from new power fields, including wind, nuclear, solar, biomass, and hydrogen, are used to form the portfolio and get the optimal weights dynamics from 2006 to 2009. It's found that the optimal investment weights...
The information-sharing on supply chain is the basis for the supply chain management, while it has some risk. The existence of destructive risk is the main obstacles for the information-sharing among the members. There must weigh the profits and risks and seek to maximize the interests under the premise of controlling destructive risk effectively in the information-sharing on supply chain. The different...
In an ageing electricity distribution infrastructure as found in many countries, measuring the impact of maintenance is becoming increasingly important. A realistic maintenance impact model will permit to improve existing maintenance strategies. This paper addresses this issue from a risk management perspective. The first part gives a short review of some of the existing mathematical models that are...
From the broking out of U.S. substandard loan crisis and the closing down of commercial banks ,we can see the important reason of suffering heavy losses is that commercial banks did not properly assess a series of facing risks. At present, China's commercial banks risk analysis is still in the traditional objective qualitative analysis phase, as for risk quantification, especially comprehensive evaluation...
Effectively and efficiently performing business processes is a key success factor for achieving economic entrepreneurial goals. Amongst others, the argument of more stringent cost pressure lead companies to enforce outsourcing activities. Thus, the management of services - both, from the service requester and provider point of view - gained importance. However, considering only economic aspects is...
The planning and effective usage of resources is a major challenge for organizations. More than ever through the global interconnections and the current economic situation the domain of resource allocation gains importance. Thus, within this paper we contribute to this research field by introducing a novel approach for dynamic activity and resource allocation using risk-aware business process simulations...
Aiming at the risk management that electricity purchasers will face in power purchase of four markets under the framework of the electricity market, two purchasing electricity models about the restrictions or non-restriction are set up by means of Variance measuring risk. Meanwhile, this paper also proposes several feasible algorithms to minimize risks, including statistical genetic algorithms (SGA)...
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...
Under the opening economic circumstances, evaluating the risk of cross-border capital flow has special significance. For effectively evaluating the risk associated with capital flow, a new evaluation index system of risk is created on the basis of fourteen influencing factors. The analytic hierarchy process is used to determine the weights of indexes and four-grade risk comment set is adopted. Using...
The increased interest in renewable energies has motivated the economic assessment study of different energy systems. Energy systems based on some natural renewable sources, as wind power, have the drawback of a random input, and then, peak user demand does not always coincide with peak power production. Regulation of output energy requires the introduction of new equipment with the capacity to store...
We develop a possibility based model with the aim of helping firms to deal with difficult-to- predict catastrophic failures. Our study is motivated by the recent economic turmoil and recent large financial firm failures. Our results suggest that specialization is an alternative to portfolio diversification in predicting catastrophic events.
Contemporary societies (from individuals to organizations) depend on services delivered by systems to achieve individual goals, meaning that a system must have engineered and guaranteed dependability, regardless of continuous, rapid and unpredictable technological and context changes. The simplest questions that brought out in the surface are to understand on how to evaluate and how much (money) should...
As P2P system has dynamic open and anonymous characteristics, and these seriously restrict P2P system of cooperation between the users and system reliability and availability. To solve the above problems, a trust model of P2P network based on reputation and risk is presented. Taking into account the influence on the calculation of confidence at different periods of trading, time decay function which...
A risk assessment model (RAM) is necessary to avoid the limitations associated with a simplistic and broad classification of applicants into a "good" or "bad" category. The absence of appropriate weights in the current evaluation system triggers the need for the development of the comprehensive model based on proven statistical application. Literature survey undertaken brought...
The purpose of this paper is to develop a conceptual model for e-government acceptance in public sector which is one of the least studied aspects of e-government. The proposed model uses theories from technology acceptance and success and the diffusion of ICT-related innovations. It integrates constructs from the technology acceptance model (TAM), the theoretical extension of the TAM (TAM2), the diffusion...
