Climate change risks consist of three basic components including sensitivity, exposure, and possibility. Uncertainty, future events, damages, and relativity are the major features of climate change risk. Climate change risk research includes two key steps: risk assessment and risk management, the former is the process, and the latter is the ultimate goal which is the basis for actions to address climate change. We present the main framework and methods for climate change risk research. A case study on China's floods risk is taken as an example of climate change risk study. Finally, we point out main aspects of climate change risk research, including ensemble-based probabilistic projection, quantitative risk assessment, risk zoning and mapping, and risk management.展开更多

These issues require efficient risk management techniques. The success of construction companies running projects in international markets depends on how the risks arise from the host country conditions as well as the project specific risk factors. Successful management of risks requires identification of risks, construction of a risk model which can be used to assess the magnitude of risks, and implementation of response strategies so that an acceptable risk-return balance can be achieved. The project success usually depends on the combination of all risks, response strategies used to mitigate risks, and a company's ability to manage them. There exists a need to develop risk models containing the risks of doing business in international markets and factors that affect manageability of these risks. One of the market's critical challenges is scheduled management and the understanding and application of program management. This paper uses systematic risk identification, classification and analysis, and measurement and response methodologies to help international contractors quantify the risks of project development and accomplishment.展开更多

Enhancement of business agility is not possible unless greater flexibility is built into IT infrastructure. More often than not, MIS's today are not flexible enough in this sense to agilely accommodate demands for system change incessantly confronting them. We have been focusing our research on MIS flexibility, its evaluation and the development of methodology for its enhancement. This paper aims to present a comparative evaluation via future oriented POC (penalty of change) analysis of system alternatives involving a case of new technology implementation. To start with, we will define the concept of MIS flexibility. We will then describe an actual case of technology implementation and define the problem it involved and go on to illustrate the evaluation procedure of MIS flexibility via future oriented POC analysis.展开更多

Buildings in Lagos have had nasty experiences from both natural and artificial disasters, claiming lives and properties in the past. This study aims at evaluating the disaster risks, vulnerabilities and response strategies in the high rise buildings in Lagos municipality. Structured questionnaire was administered to building owners, estate managers and disaster managers who manage the high rise buildings. The information obtained was supplemented by personal interviews conducted with tenants and rescue organizations. The study identified collapse of building, fire out break, and communication and power failure as the most likely potential disasters, power failure and collapse had the highest severity of impact, and the degree of preparedness achieved to confront the disasters was below satisfaction. However, the specific status of the response strategies was as expected, but there was room for improvements. The potential disasters were natural, human and environmental and the most vulnerable sectors were other properties rather than the high rise buildings themselves. The magnitude of risk levels could be contained with the level of response strategies already achieved if coordinated.展开更多

In this paper, based on the fuzzy characteristics of contract risks, and overcoming the traditional disadvantages of analytic hierarchy process (AHP), the fuzzy analytic hierarchy process (FAHP) of contract conclusion is proposed for meeting the actual need of equipment procurement contract risk assessment, and implementing the risk factors qualitative and quantitative assessments of different working nodes in contract conclusion. Thus, a scientific and reliable important basis is provided for the risk management of equipment procurement contract.展开更多

To achieve desired results, managers have to implement methods of evaluating and mitigating risk as part of a process well elaborated. Security risk management helps managers to better control the business practices and improve the business process. An effective risk management process is based on a successful IT security program. This doesn't mean that the main goal of an organization's risk management process is to protect its IT assets, but to protect the organization and its ability to perform their missions. During this process, managers have to take into consideration risks that can affect the organization and apply the most suitable measures to minimize their impact. The most important task is choosing the best suited method for analyzing the existing risk properly. Several methods have been developed, being classified in quantitative and qualitative approaches of evaluating risk. The purpose of this paper is to present the advantages and disadvantages of each approach taking current needs and opportunities into consideration.展开更多
