Spec-VALUe, a rigorous scenario-driven approach for the description and validation of complex system functionalities at the early stages of design, is presented.
It was this type of rigorous, scenario-driven planning that helped health officials and other key decision-makers become familiar with the challenges of addressing an influenza pandemic prior to the arrival of novel H1N1.
Similarly, in the rigorous contact reduction scenario the effect of delayed response on attack rate was more pronounced in the Albany model, due to lower effectiveness of interventions in a PNG setting.
Using a more rigorous simulated anaphylaxis scenario and prospective study design, we have clearly shown that device design is a critical factor in successful AAI use and that success rates using commonly prescribed devices are worryingly low even 6 weeks following training.
These results are vital to the foresight process, since they constitute the basis for generating driving factors and trends to be applied in the subsequent stages of rigorous imagining and scenario-building.
A novel and practical discriminator is developed with a rigorous analysis of the scenario characteristics.
Together these problems emphasise the need for careful and rigorous issue-framing and scenario specification as the foundation for assessment.
Rigorous computational experiments in scenarios with and without convex obstacles show the feasibility and efficiency of our approach.
Modelling has much to offer here, through its ability to distil theoretical mechanisms to formal expressions and to afford both quantitative and rigorous analysis of hypothetical scenarios via well-established techniques.
Conducting rigorous assessments of the scenarios thus defined presents further difficulties, not least because of gaps in data, limitations of knowledge and the inevitable amplification of uncertainties involved in devising and parameterising complex and linked models.
The CO2 tax is increased gradually from 4.5 EUR/tCO2016016) to 20.0 EUR/tCO2030030) in scenarios 3, 5, and 7. A more rigorous policy is applied in scenarios 4, 6, and 8, where the CO2 tax is gradually increased from 4.5 EUR/tCO2016016) to 55.0 EUR/tCO2030030).
