-agricultural sector is considered as a risk-mitigating strategy by rural Pakistani households. This issue has already been addressed but … whether ex ante engagement in the non-agricultural sector is partly motivated by a desire to mitigate risk. The main feature … of the paper is the use of an ex ante food vulnerability estimate. Vulnerability is defined as the probability of falling …

In R\&D projects, managers face a high degree of uncertainty due to their lack of experience with innovative products …. However, managers, usually within a group, have to decide under uncertainty, to make the projects advance. In this context … framework that formalizes the collective decision-making process under uncertainty is proposed. This framework illustrates how …

This paper addresses the integration of ill-know requirements (imprecision or uncertainty on f quantities or due dates … requirements are analysed and a representation model based on mathematical models of uncertainty is proposed. Moreover, a method is …

any quantified uncertainty levels is problematic because it may lead to unjustified attention to the extreme scenarios …

This work deals with strategies of risk management techniques in projects and portfolios in the situation of radical … innovation. Existing literature suggests different methods of risk management at the level of 1) projects (S1) (unknown reduction … by selecting a priori the less uncertain projects, depending on the identified market and technological risk) 2 …
