1. Introduction The potential of remote sensing for the monitoring of the Earth environment and the detection of its temporal variations is well known. A variety of applications in the fields of flood monitoring, forest fire detection, landslide and subsidence, surface deformation and land cover variations were shown in the last ten years using space optical and radar data. However, the real-ti...

As evidenced through both a historical and contemporary number of reported over-runs, managing projects can be a risky business. Managers are faced with the need to effectively work with a multitude of parties and deal with a wealth of interlocking uncertainties. This paper describes a modelling process developed to assist managers facing such situations. The process helps managers to develop a...

We define (d, n)−coherent risk measures as set-valued maps from Ld into IR satisfying some axioms. We show that this definition is a convenient extension of the real-valued risk measures introduced by Artzner, Delbaen, Eber and Heath (1998). We then discuss the aggregation issue, i.e. the passage from IR−valued random portfolio to IR−valued measure of risk. Necessary and sufficient conditions o...

On a land suitability assessment map that is derived from an overlay of n parent maps, each bearing k land capability categories, how many permutations of land suitability scores can there be when the scores are calculated by the commonly used rating and weighting method? In this paper, we estimate that this number is between k n(n−1) 2 and kn+1!/(kn!kn−1! · · · k!)k−1.

When the stakes of stakeholders are not properly incorporated during early phases of a planning process, it may later give rise to severe conflicts. The issue of how to deal with stakeholders in regional water management has been a subject of ongoing debate in the Netherlands. This paper promotes a ‘platform’ approach where stakeholders collectively attempt to develop plans for regional water m...

Risk management is of great importance to outsourcing deals. While the traditional outsourcing focuses on risk management by one partner (typically the outsourcer), this paper proposes a risk sharing approach. Such an approach requires the identification and prioritization of risks from both the outsourcer’s and the service provider’s perspective to identify areas of shared interest. The analys...

This article is devoted to the study cashflow maps used in the computation of value-at-risk (VaR). Properties and characteristics of the approaches found in the literature are presented and two new approaches are introduced. The goal of this paper is to study the quality of these maps. This is done by calculating the risk induced by the difference between the mapped cashflows and the original one.
