    For most companies, it is a reality to face uncertainties when conducting complex projects focused on the implementation of Information Systems (IS) and, as a consequence, cost-benefit evaluation of this kind of projects has become a difficult task. In this context, Real Options Theory (ROT) has proved to be a viable alternative to provide methods to evaluate complex projects, not only in Information Technology but in many other economics and business areas. This paper intends to demonstrate how ROT can be applied to evaluate complex Information Technology projects, exploring a case study involving an implementation project of an Enterprise Resource Planning (ERP). In the case study, two distinct solutions for the implementation of an ERP were evaluated, demonstrating the applicability of ROT to such complex situations

    A methodology for the selection of new technologies in the aviation industry

    The purpose of this report is to present a technology selection methodology to quantify both tangible and intangible benefits of certain technology alternatives within a fuzzy environment. Specifically, it describes an application of the theory of fuzzy sets to hierarchical structural analysis and economic evaluations for utilisation in the industry. The report proposes a complete methodology to accurately select new technologies. A computer based prototype model has been developed to handle the more complex fuzzy calculations. Decision-makers are only required to express their opinions on comparative importance of various factors in linguistic terms rather than exact numerical values. These linguistic variable scales, such as ‘very high’, ‘high’, ‘medium’, ‘low’ and ‘very low’, are then converted into fuzzy numbers, since it becomes more meaningful to quantify a subjective measurement into a range rather than in an exact value. By aggregating the hierarchy, the preferential weight of each alternative technology is found, which is called fuzzy appropriate index. The fuzzy appropriate indices of different technologies are then ranked and preferential ranking orders of technologies are found. From the economic evaluation perspective, a fuzzy cash flow analysis is employed. This deals quantitatively with imprecision or uncertainties, as the cash flows are modelled as triangular fuzzy numbers which represent ‘the most likely possible value’, ‘the most pessimistic value’ and ‘the most optimistic value’. By using this methodology, the ambiguities involved in the assessment data can be effectively represented and processed to assure a more convincing and effective decision- making process when selecting new technologies in which to invest. The prototype model was validated with a case study within the aviation industry that ensured it was properly configured to meet the

    Currently, museums are struggling to develop and present their expertise by focusing on the interactive relationship with museum visitors. In order to meet the needs of museum exhibitions, an efficient and workable design process is of primary importance in order to work to develop high quality museum exhibitions. It would be advantageous to generate a design method which allows designers and curators to undertake design work in the context of museum exhibition project. Based on an empirical analysis, this paper suggests that a systematic transformation develops specific aspects of detailed design to carry out its principle, and that the implementation of these aspects can be viewed as a process of organizational criteria of museum exhibition design projects. The paper is concerned with design process in organizations seeking to act systematic criteria in the design activity on the application of museum exhibition project development in complex theories. In particular, this study is developed to address the following objectives: a) To identify the characteristics and concepts of the design activity as they relate to museum exhibition design; b) To contribute to a more complete understanding of design process by developing guidelines for adoption in projects. c) To establish the benefits of the application of design guide theory to the practice of museum exhibition design; Keywords: Museum Exhibition; Design Criteria; Design Process</p

    Use of an agile bridge in the development of assistive technology

    Get PDF
    Engaging with end users in the development of assistive technologies remains one of the major challenges for researchers and developers in the field of accessibility and HCI. Developing usable software systems for people with complex disabilities is problematic, software developers are wary of using user-centred design, one of the main methods by which usability can be improved, due to concerns about how best to work with adults with complex disabilities, in particular Severe Speech and Physical Impairments (SSPI) and how to involve them in research. This paper reports on how the adoption of an adapted agile approach involving the incorporation of a user advocate on the research team helped in meeting this challenge in one software project and offers suggestions for how this could be used by other development teams

    Mobile Life: A Research Foundation for Mobile Services

    Get PDF
    The telecom and IT industry is now facing the challenge of a second IT-revolution, where the spread of mobile and ubiquitous services will have an even more profound effect on commercial and social life than the recent Internet revolution. Users will expect services that are unique and fully adapted for the mobile setting, which means that the roles of the operators will change, new business models will be required, and new methods for developing and marketing services have to be found. Most of all, we need technology and services that put people at core. The industry must prepare to design services for a sustainable web of work, leisure and ubiquitous technology we can call the mobile life. In this paper, we describe the main components of a research agenda for mobile services, which is carried out at the Mobile Life Center at Stockholm University. This research program takes a sustainable approach to research and development of mobile and ubiquitous services, by combining a strong theoretical foundation (embodied interaction), a welldefined methodology (user-centered design) and an important domain with large societal importance and commercial potential (mobile life). Eventually the center will create an experimental mobile services ecosystem, which will serve as an open arena where partners from academia and industry can develop our vision an abundant future marketplace for future mobile servĂ­ces

    WHY FUZZY ANALYTIC HIERARCHY PROCESS APPROACH FOR TRANSPORT PROBLEMS?

    Get PDF
    The evaluation of transport projects has become increasingly complex. Different aspects have to be taken into account and the consequences of the problems are usually far reaching and the different policy alternatives are numerous and difficult to predict. Several pressure or action groups have also emerged causing an even more complex decision making process. The use of multi criteria analysis for the evaluation of transport projects has increased due to this increasing complexity of the problem situation. At the same time, the importance of stakeholders within this evaluation process should have been recognized. Researches on transport projects are generally carried out to provide information to policymakers that have to operate within restrictive parameters (political, economical, social, etc…). Researchers should therefore take greater account of the different priorities of stakeholders such as policymakers, private enterprises and households. These stakeholders should be incorporated explicitly in the evaluation process. The Analytic Hierarchy Process is one of the Fuzzy Multiple Criteria Decision Making methods. It can be applied in a very broad range of applications of decision problems. Logistics, urban planning, public politics, marketing, finance, education, economics are a part of this wide application area. In transport subjects it can be used for the evaluation of transport policy measures or decision making problems. Due to its wide range application area, it has been an exciting research subject for many different field researchers. The aim of this paper is to introduce AHP method and to offer how to benefit it for the preference of urban planners in transport problems. This paper is composed of two main parts. First part consists of the literature survey regarding with the AHP and its application areas. The advantage of methods had been mentioned. Second part focuses on a sample application of AHP technique. The study uses AHP technique to determine the selection criteria in the transhipment port selection decision-making process. Keywords: Analytic Hierarchy Process, Multi criteria analysis, Transshipment port selection.
