description: Sustainability science primarily emerged from the severe global events that had and were unfolding approximately a quarter century ago; evidence from the literature review conducted in Chapter 1 exemplifies this point. From this situation surfaced a number of concepts and techniques that have been tested and continue to be assessed. The first step of the methodology is the literature review in which the overall picture of the discipline is established and what direction sustainability related science is headed. The literature review found that the forefront of this research endeavours to adapt quantitative sustainability concepts into a method that can assess and analyse a geographical area. To undertake this challenge, the index of sustainable functionality (ISF) model is used via a quantitative multi-criteria method. This method of sustainability assessment establishes a historical and current state of functionality within a geographical area by producing a trend-like record. In sustainability terms, the ISF model uses an approach that calculates the adaptive quantitative results of a geographical area over a record period of time; the methodology in Chapter 2 describes the model’s concept of assessment by way of actions via societal performance and ranking. The structure of the model is based on an engineering viewpoint; its key components umbrella a societal framework that encompasses an intertwined relationship using a triple bottom line (TBL) approach. The formation of this model is founded on a number of aspects, ideas and methodologies based on initial models of sustainability assessment. These initial forms – to mention a few include environmental accounting, integrated assessment and ecological footprint – have helped to establish the current settings of the discipline of sustainability science and the significance of related research. The methodology is broken down into two main components: (1) structure methodology which is framed around five steps that identify and define variables and (2) mathematical formulation which is used to calculate ISF records. An examination of the formulae used, also shows evidence that the principal ideas can be linked to a redefinition of sustainability; this is not the intention of this study, though in a quantitative sense the use of an action being functional or dysfunctional within society can be interpreted in this way. Actions include perspectives, functions and indicators, and sub-indicator(s); the analysis process is limited to the use of two types of data: datasets based on indicators and sub-indicator(s) used to formulate functions and data from the weightings process, that being, from the expert panel and the community telephone questionnaires. The data from the weightings process utilises the formulated functions and is the basis for the formulation of the system- vi perspective cross-reference matrix. This design is a stepladder process methodology and is the fundamental concept of the ISF’s multi-criteria assessment. This report has two applications that examine the Australian regions of South East Queensland (SEQ) and the State of Queensland; the proposed index-based model is tested over a time span of 25 years from 1980 to 2005. The primary focus of the methodology is aimed at the SEQ region, acting as the model’s core focus for its experimentation and development. The SEQ region is broken down into four sub-regions which encompass a total of eighteen councils using the council structure from pre- 15 March 2008. For these regions ISF records are developed and analytically discussed as results in Chapter 3. The results, once merged, form the ISF of SEQ and detail a slow-to-moderate increase in level of functionality. The result in sustainability terms formulate an increase in functional growth rate of 15.38%, equating to an average annual growth rate of 0.62%. For the span of the study this is positive result, showing evidence of a growth in knowledge and awareness of sound TBL measures region-wide. As an extension to the SEQ study, an ISF application of the entire State of Queensland is conducted in Chapter 4. The ISF of the State of Queensland is a case study that uses similar methodology and structure to the SEQ project and demonstrates the applicability and scalability of the model at large. For the State of Queensland, the ISF result closely mirrors its smaller SEQ corner; it is inferred that since SEQ is partially the concluding ISF result of the State application, similar ISF records would be produced. In addition to the main report, there are six annexes that further detail, support and explain subject matter and findings throughout the dissertation (Annex 1 thru 6). Due to the length of the annexes they have been included as supplementary material. As the key contributing factor of this report, the development of an ISF model, using a quantitative multi-criteria method, reveals a transposable approach to assessing other areas within Australia and internationally. It is this transposability via produced traceable records that current and future generations may better utilise decision-making and managerial planning when considering the sustainable development crisis. The intentions of this report is not to produce a solution to this crisis, it is aimed at adding to the knowledge base of the sustainability science and promoting a cleaner, safer society with sustainable higher standards of living that support future generations. From this standpoint, it is hopeful that the methodologies utilised in this report can further the interdisciplinary work and help bring together technical, communicative innovation in a vital field of research.
