If it is assumed that the Sustainability index is a linear agglomeration
function of products between indicators and corresponding weighting
coefficients, we can write the aggregation function, which is presented in the
form of additive convolution. If it will be adapted that each of the criteria is
weighted by the respective factor, the sum of criteria multiplied with the
corresponding factor will lead to the Sustainability Index .
3.1.5. Resilience Index for Global Warming
Resilience Index is integral of the Sustainability Index between the time of
sudden change of the respective indicator and time when it resume steady state
value. The resilience index for an global warming system is composed of the
following elements: economic, environmental, technological and social the
resilience indicators [8,9,10].
