This paper presents a new decision support model COSIMA-DSS that examines socio-economic feasibility risks involved in the implementation of transport infrastructure projects. The model makes use of conventionally costbenefit analysis embedded within a wider multi-criteria analysis. The basic approach set out in the paper looks upon the mix between so-called “hard” and “soft” evaluation criteri...

The objective of this study is to review and develop methods and measures for assessing the costs and benefits of medical information systems. The paper discusses different approaches to evaluating medical information systems and discusses the rationale behind analysing the costs and benefits of such systems. It also lists previous studies, which report costbenefit analysis of medical informati...

When collecting subjective human ratings of items, it can be difficult to measure and enforce data quality due to task subjectivity and lack of insight into how judges arrive at each rating decision. To address this, we propose requiring judges to provide a specific type of rationale underlying each rating decision. We evaluate this approach in the domain of Information Retrieval, where human j...

Sustainability is defined in terms of four overlapping positions, ranging from very weak to very strong sustainability. The core idea is of a non-declining capital stock (including natural capital) over generational time. Weak sustainability positions emphasise capital substitution possibilities and the power of technical process to mitigate resource depletion and pollution problems. Climate ch...

Many methods aimed at cost-benefit analysis for IT-projects can be found in literature. These all have one thing in common: actual usage is limited. In our view this is due to two factors: the criteria to take into account in the analysis are fixed and the process to support the analysis is lacking or at least flawed. In this paper an approach towards costbenefit analysis will be described that...

software reuse, costbenefit analysis, decision support The field of software reuse is attracting increasing attention from academics and practitioners who recognize the economies to be gained from reducing duplication of software development effort. However, development for reuse requires additional costs that are difficult to justify under a single-project management view. Since reuse benefits...

This paper looks at the concept of reputation from four angles: costbenefit, semiotics, quality and complexity. The complexity outlook may include all the other approaches in certain conditions but is in comparison wider, deeper, evolutionary and more fickle. It can embrace apparently contradictory states that evolve through interaction. The focus is on ambiguity, one of the less-known principl...

Usability is an important quality characteristic of software (SW) products and systems. Usability costbenefit analysis models outline the potential benefits and costs of usability. These models are important for selling the usability activities for management. The implications of open source software (OSS) development context on usability cost-benefit considerations have not been addressed. Bas...

A large number of modelling tools and approaches that can be used for supporting waste management decisions at different levels in society have been developed. Examples include Life Cycle Assessment (LCA) and different types of Material Flow Analysis (MFA), CostBenefit Analysis (CBA), Life Cycle Costing (LCC), different types of optimizing models, etc. The shear number of different methods that...
