Conceptual modelling: choosing a critical infrastructure modelling methodology

This paper reports on further research undertaken regarding systems modelling as applied to critical infrastructure systems and networks and builds upon the initial modelling research of Pye and Warren (2006a). We discuss system characteristics, inter-relationships, dynamics and modelling of similar systems and why modelling of a critical infrastructure is important. In overview we compare four modelling methods and techniques previously
used to model similar systems and discuss their potential transference to model critical infrastructure systems, before selecting the most promising and suitable for modelling critical infrastructure systems for further research.

Preface to CMLSA 2007

Life sciences applications typically involve large volumes of data of various kinds and a multiplicity of software tools for managing, analyzing and interpreting them. There are many challenging problems in the processing of life sciences data that require effective support by novel theories, methods and technologies. Conceptual modelling is the key for developing high-performance information systems that put these theories, methods and technologies into practice. The fast-growing interest in life sciences applications calls for special attention on resource integration and collaborative efforts in information systems development.

Integrating the conceptual and practice worlds : a case study from Architecture

A compelling challenge for tertiary educators is to respond meaningfully to pressures to provide curricula that translate readily into realworld professional experience. To explore the synergies of an integration of the conceptual and practice worlds, this paper draws on a program, which the author evaluated, that was part of a Committee for University Teaching and Staff Development funded project for students of architecture and construction. The aspect discussed here, Composing Architecture—The Music Room, involved 74 second year students at Deakin University in semester 2, 2001. The case study is used as an illustration of curriculum design, including assessment, to explore how it met the aims of creating learning experiences that were purposeful, rich in their complexity, and mirrored the demands of the profession in a supportive environment that fostered development. One of the major aims was to model professional practice within the academy—in a sense, to enter into a dialogue between the academy and the profession—with the quality of that dialogue being determined by the accuracy or authenticity of the modelling. With this focus, having articulated and discussed the stated educational challenge that this project was intended to meet, the paper tests this against the attributes of authenticity in the environment of education as delineated by Martin-Kniep (2000) and, in so doing, questions some of her claims. Although some theorists (eg, Petraglia, 1998) contend that to prescribe what counts for authenticity is impossible, it is hoped that some insights into linking the academy and the profession will be gained.

A conceptual model for security outsourcing

This research analyses the current literature on IT security outsourcing and the organisational attitudes towards this approach to determine the applicability of outsourcing IT security in a commercial environment. A conceptual model is developed as the main goal of research which provides guidance in the process of outsourcing IT security functions to a third-party security service provider. The research conducted has established a complete process for outsourcing IT security.

Causal modelling of construction disputes

Disputes have become an inherent feature of the construction industry. A plethora of studies have been undertaken to identify the causes of disputes so as to determine the most appropriate prevention and resolution strategies. While it is widely known what the main causes of dispute are, they still remain prevalent in the Australian construction industry. This is because there is a need to better understand the complexity and interplay between causal variables. Using data derived from the
literature a conceptual causal model of construction disputes is developed. The model identifies the key causal variables and pathogens that can contribute to disputes.

Security analysis and modelling framework for critical infrastructure systems

The provision and delivery of many of the services that modern society enjoys are the result of ubiquitous critical infrastructure systems that permeate across many sectors of the Australian community. Moreover, the integration of technological enhancements and networking interconnections between critical infrastructure systems has heightened system interdependence, availability and resilience, including the efficient delivery of services to consumers within Australia's industrialised society. This research delivers a system security analysis and system modelling framework tool based on an associated conceptual methodology as the basis for assessing security and conceptually modelling a critical infrastructure system incident. The intent to identify potential system security issues and gain operational insights that will contribute to improving system resilience, contingency planning development applicable to disaster recovery and ameliorating incident management responses for Australian critical infrastructure system incidents.

Beyond e-commerce: an entrepreneurial business modelling method for profitable e-venturing

E- business is used as a term that embraces e-commerce, its commercial exchange or transaction component. Both are subsets of a larger concept, e-venturing. E-business is a major disruptive innovation that is rapidly changing many of the accepted norms of effective management. So the paper revisits and reassesses several established principles of economics, strategy and entrepreneurship to place them in the context of the forces driving the emerging e-business economy. Entrepreneurship is applied as a 'framework enrichener', model-building tool and critical organisational behaviour to guide integration of e-business strategy into the total organisational strategy of a profit-seeking firm This permits development of a new business modelling process, labelled 'map and locate', that adapts a combination of entrepreneurial and strategic imperatives to the internet environment. The process assumes that value-provision, competitive distinction and profitability are the three essentials of any successful e-business strategy design and execution. Apart from its general conceptual role of linking strategic and entrepreneurial thinking, the 'map and locate' modelling process can be used as a practical tool for specific performance in a variety of circumstances. It focuses on learning and the development of metrics useful for measuring progress towards achievement of target outcomes.

Semantic data modelling and visualization using Noetica

Noetica is a tool for structuring knowledge about concepts and the reIationships between them. It differs from typical information systems in that the knowledge it represents is abstract, highly connected, and includes meta-knowledge (knowledge about knowledge). Noetica represents knowledge using a strongly typed graph data model. By providing a rich type system it is possible to represent conceptual information using formalized structures. A class hierarchy provides a basic classification for all objects. This allows for a consistency of representation that is not often found in `free' semantic networks, and gives the ability to easily extend a knowledge model while retaining its semantics. Visualization and query tools are provided for this data model. Visualization can be used to explore complete sets of link-classes, show paths while navigating through the database, or visualize the results of queries. Noetica supports goal-directed queries (a series of user-supplied goals that the system attempts to satisfy in sequence) and pathfinding queries (where the system finds relationships between objects in the database by following links).

Preliminary insights from a multiple case study on process modelling impact

Process modelling – the design and use of graphical documentations of an organisation’s business processes – is a key method to document and use information about business processes in organisational projects. Still, despite current interest in process modelling, this area of study still faces essential challenges. One of the key unanswered questions concerns the impact of process modelling in organisational practice. Process modelling initiatives call for tangible results in the form of returns on the substantial investments that organisations undertake to achieve improved processes. This study explores the impact of process model use on end-users and its contribution to organisational success. We posit that the use of conceptual models creates impact in organisational process teams. We also report on a set of case studies in which we explore tentative evidence for the development of impact of process model use. The results of this work provide a better understanding of process modelling impact from information practices and also lead to insights into how organisations should conduct process modelling initiatives in order to achieve an optimum return on their investment.

Critical infrastructure systems : security analysis and modelling approach

A system security analysis and system modelling framework tool is proposed adopting an associated conceptual methodology as the basis for assessing security and conceptually modelling a critical infrastructure system incident. The intent is to identify potential system security issues and gain operational insights that will contribute to improving system resilience, contingency planning, disaster recovery and ameliorating incident management responses for critical infrastructure system incidents. The aforementioned system security analysis and modelling framework is applied to an adverse critical infrastructure system incident case study. This paper reports on the practical application of the framework to a case study of an actual critical infrastructure system failure and the resultant incident implications for the system and the wider regional communities.

Modelling interplay in normative social systems: towards a heuristics formalism of agents and networks

The need for guiding model formulation of normative social systems in support of a digital ecosystem is introduced. Normative social systems improve the understanding of computational social processes in simulation and experimentation, and provide support for digital ecosystem developments. However, a successful simulation requires the appropriate implementation of a conceptual model. It is proposed that an heuristic formalism of agents, networks and environments, complements the conventional creative approach to model formulation by guiding the formulation of conceptual models via abstract components and facilitate interface with other components in a digital environment.

Diffusing knowledge-based core competencies for leveraging innovation strategies: modelling outsourcing to knowledge process organizations (KPOs) in pharmaceutical networks

As pharmaceutical firms try to market their products and reduce costs, vertically integrated structureshamper innovation processes. Yet, pharmaceutical firms must innovate to compete. Outsourcing knowledgeintensive activities to knowledge process organizations (KPOs) serves to reduce innovation process obstacles.Grounded in diffusion theory and strategic management literature, this conceptual paper explores fourinterrelated strategic concepts: core competencies, economies of scale and scope, knowledge sharing,and learning. This paper claims that (a) accumulated core competencies of multinational pharmaceuticalcompanies (MPCs) erode over time and these companies become dependent on KPOs (b) MPCs mustunderstand how KPOs manage core competencies (c) economies of scope benefit KPOs enabling them tosustain competitive advantages for their MPC partners, meanwhile the benefits from economies of both scaleand scope shift from MPCs to KPOs (d) KPOs need to monitor their rate of learning to remain competitive.The paper identifies implications for industrial managers and directions for future research.
