This paper presents some convex stochastic programming models for single and multiperiod inventory control problems where the market demand is random and order quantities need to be decided before demand is realized. Both models minimize the expected losses subject to risk aversion constraints expressed through Value at Risk (VaR) and Conditional Value at Risk (CVaR) as risk measures. A sample ...

In this paper, we consider the problem of optimal reinsurance design, when the risk is measured by a distortion risk measure and the premium is given by a distortion risk premium. First, we show how the optimal reinsurance design for the ceding company, the reinsurance company and the social planner can be formulated in the same way. Second, by introducing the “marginal indemnification function...

Risk is inherent in all human activities, both personal and professional. While the number and variety of risks have grown and changed dramatically throughout history, the basics remain the same: risk of loss of life, limb, health, livelihood, or property due to predictable events (reduced income upon reaching the mandatory retirement age) or to unpredictable events (loss of life in an earthqua...

The paper is based on a general conceptual supply chain flow risk model developed in an earlier paper, a literature review and case studies. The paper has the title "Developing a supply chain risk model" and is reported as a final paper at the NOFOMA 2005 conference. The literature review has been focusing articles and reports/books on supply chain management. Some of its findings have earlier ...

The recent financial turbulences raise questions on how risk analysis is conducted. Regulatory requirements and professional standards have been introduced in the last decade in order to obtain a more reliable internal control on financial reporting process with a new emphasis on business processes. However, there are no standards yet available on how business processes should be captured for f...

Risks are factors frequently beyond control and can negatively impact organizational ability to achieve the established goals. These are factors that create differences between the reality and an ideal situation. Accurate evaluation of potential risks is integral to a large-scale project, especially when the project has enormous and longterm organizational implications. In that aspect, the risk...
