Airport Crisis Management Scenario

The Airport Crisis Management Scenario is a small fictional example of how it is envisage that a system of systems can be employed in practice to deal with a crisis situation. The crisis captured in the scenario is that of a fire breaking out at one of the airport's gates. It is envisaged that the crisis situation can be better resolved via the use of a system of systems. This involves such things as sharing critical information over PDAs to be issued to the rescue workers, the use of a geographical information system with corresponding GSP tracking devices, sharing the CCTV video streams between the involved organisations and the use of a central information store to record details on the people who need treatment, etc. So is this envisaged system of systems useful for the crisis scenario and if so how useful? And alternatively are there better options where the airport's limited financial resources can be spent? For example could the airport maintain an on-site medical team or have an on-site fire fighting team.

CATMOS: Capability Acquisition Tool with Multi-Objective trade-off Support

CATMOS is an MDE tool the provides support for capability-based planning, to facilitate systems of systems acquisition. CATMOS is targeted at acquisition scenarios that involve significant costs. In these situations, a better understanding of uncertainty can increase confidence in decisions, and thus in investments to be made in acquisition. In CATMOS, users model their problem scenario by defining a set of desired system capabilities and a set of available components. CATMOS then generates a set of output models that represent combinations of components that can meet the capability requirements of the scenario. Every solution model has a cost and a capability score, and the solution set can be represented as a Pareto front of capability versus cost (i.e. no solution dominates any other in all objectives), which can be used by stakeholders in decision making.
Note: Unfortunately, the CATMOS tool that generated these models is unavailable due to commercial restrictions. For more information, contact jw [at] cs [dot] york [dot] ac [dot] uk.

Sensitivity Analysis Results

CATMOS produced a Pareto front of satisfied scenario models, to which sensitivity analysis has been applied. These models, plus the associated reports which were generated, can be downloaded below. Furthermore, you can inspect two example reports and view a high resolution version of the frontier analysis plot provided in the paper.
