Transportation networks are open and accessible, by design, and thus vulnerable to malicious attacks. Transportation networks are integral parts of larger systems, where individual transportation networks form a network-of-networks within a defined geographical region. A security incident on an asset can propagate to new security incidents in interconnected assets of the same or different netwo...

Commitments play a central role in multi-agent coordination. However, they are inherently uncertain and it is important to take these uncertainties into account during planning and scheduling. This paper addresses the problem of handling the uncertainty in commitments. We propose a new model of commitment that incorporates the uncertainty, the use of contingency analysis to reduce the uncertain...

We present a hill-climbing algorithm to solve planning problems with temporal uncertainty. First an optimistic plan that is valid when all actions complete quickly is found. Then temporal reasoning techniques are used to determine when the plan may fail. At time points that cause an unsafe situation, contingency branches are inserted. We describe our planner PHOCUS-HC, give preliminary results,...

The IS development industry is currently undergoing profound changes. The well established, large system developers (hubs) take the lead in establishing partner networks with much smaller, often young companies (spokes). This paper takes the perspective of these spokes and seeks to understand their motivations for entering into such partner networks. Drawing on research of strategic alliances a...

This study examines the business value associated with business intelligence (BI) systems, based on the premise that business value is largely contingent on system type and its unique contribution. The study adopts a process-oriented approach to evaluating the value contribution of BI, arguing that it stems from improvements in business processes. The study develops and tests a research model t...

Worst case scenarios for pandemic influenza planning in the US involve over 700,000 patients requiring mechanical ventilation. UK planning predicts a 231% occupancy of current level 3 (intensive care unit) bed capacity. Critical care planners need to recognise that mortality is likely to be high and the risk to healthcare workers significant. Contingency planning should, therefore, be multi-fac...

Interactive epistemology in dynamic games studies forms of strategic reasoning like backward and forward induction by means of a formal representation of players’ beliefs about each other, conditional on each history. Work on this topic typically relies on epistemic models where states of the world specify both strategies and beliefs. Strategies are conjunctions of behavioral conditionals of th...

There has been much recent interest in planning problems with deterministic actions but stochastic observations. Examples include Mars rover planning, robot monitoring tasks and the Rocksample domain from the planning competition. However, theoretical results show that in general these problems are as hard as solving partially observable Markov decision problems (POMDPs). We propose an approach...
