Formulating and delineating a problem and presenting a solid proposal for follow-up research is a challenge for any strategy or policy analyst. This paper describes how at TU Delft students in policy analysis and engineering management learn how to use a systems approach for exploring and analyzing complex problem situations. Their analysis should result in a clear and consistent problem framing, including definition and scope of the problem, the parties involved and their interest and power, possible strategies, relevant uncertainties, and recommended further research.

Despite the relative maturity of knowledge management, the problem of facilitating knowledge creation and sharing at multiple organizational levels in a uniform way is still crucial. Moreover, managing knowledge at each organizational level implies a number of critical heterogeneities (representational, semantic, etc.) which current solutions do not address adequately. In this paper we present a faceted ontology which addresses the content, context, community, domain and business issues of knowledge management. We describe the ontology, its applicability and its benefits in three Knowledge Management System implementations.

The dynamic and uncertain scenarios that economic organizations have to face force them to deeply rethink themselves and their structure through an internal innovation process aimed at making them more reactive and proactive. Organizations can be viewed as systems whose components (people, team, groups, organizations) are joined by formal and informal relationships, and any process of internal change requires complex negotiations based on them. It is therefore of paramount importance to perceive accurately the network of informal relationships and to actively manage them. On the basis of the concept of distance between individuals and making use of the social network analysis we provide a methodology for determining both the actual network of relationships that links all actors in the organization and an index (IDO, Informality Degree of Organizations) able to measure the level of informality prevailing within an organization. IDO index gives both theoretical and practical indications to the management for successfully implementing an internal change policy.

This paper studies the co-evolution of the GPU (graphics processing unit) and PC (personal computer) game sub-systems, with respect to graphics performance delivered to end-users during game play. Employing the concept of the reverse salient - a component which trails in technological performance and thus hinders potential system-wide development - the paper develops time-gap and performance-gap measures of reverse salience and applies them in an empirical study. Additionally, the paper evaluates technological pressure, which is equivalent to the amount of technological performance delivered in a given period of time. The results firstly identify the PC game sub-system as the reverse salient, trailing at a steady time-gap and with increasing performance-gap. Secondly, the results show that technological pressure increases continuously over the time frame of analysis.

This paper describes the successful application of management techniques to a R&D power project created for developing new technologies to reduce connection costs of low income customers to the power utility grid. Such innovations will speed up the process of extending the power supplying benefits to all inhabitants of the Bahia State, in Brazil, through a program called universalization. The paper shows the R&D projects rules established by the Brazilian regulatory agency and the scenery in which this project was conceived. It describes the project management approach used to cope with the challenges ahead of us, the project planning, organization and execution details of the entire process. The products were successfully developed and they are finally shown with recommendations for the future of such products.

The Analytical Strategic Environmental Assessment (ANSEA) is a relatively new tool that targets to manage the ongoing shortfalls and infeasibilities especially in strategic decision-making levels of SEA process. The ANSEA incorporates the phase of Multi-Criteria Analysis (MCA) into the assessment scheme in order to perform more sensitive approach to the real decision-making context in environmental planning & management. This paper proposes an approach based on Fuzzy Axiomatic Design (FAD) to assign suitable MCA technique during execution process of ANSEA. The proposed decision aid mechanism is expected to ensure additional contributions for enhancing the current ANSEA procedure in practice.

Ben Abdelaziz et al. (2008) have shown that any non-dictatorial fuzzy social choice function is vulnerable to strategic manipulation, when individuals express their preferences trough fuzzy weak relations on the set of alternatives. This paper proposes a new definition of fuzzy manipulability and dictatorship of fuzzy social choice functions. For this purpose, the decomposition of fuzzy weak relations in terms of symmetric and regular components is considered and a parallel result is provided. The proof is done by induction on the number of individuals.
Ben Abdelaziz等人(2008)表明，当个体通过备选集合上的模糊弱关系表达自己的偏好时，任何非独裁模糊社会选择函数都容易受到战略操纵。本文提出了模糊社会选择函数的模糊可操纵性和专政性的新定义。为此，考虑了模糊弱关系在对称分量和正则分量上的分解，并给出了一个并行结果。证明是通过对个体数量的归纳法完成的。

Computer Human interaction (CHI) capabilities are critical for successful systems development life cycle (SDLC) in order to manage information systems (IS) effectively. CHI capabilities play crucial roles in interfacing information technology (IT) deployment with organisational goals. It is said that success of IT deployment is dependent on a successful process, usability, usefulness of IS products and services which are CHI centric. End-users in the organisation contribute the most towards CHI issues and their capabilities influence success of IT deployment projects. However, modern SDLC models are based more on organizational needs than understanding CHI capability needs. This incapability shows up in the form of poor reflection of user-intentions to use the services in post implementation stages. Insensitivities of IT acquirers towards end-users contribute to the gap between satisfying organizational needs, end-user deliveries and supporting organisational goals in the process. This problem can be addressed by carefully integrating end-user capabilities issues in the SDLC process to achieve a truly human-centered IS development. In this paper a framework is suggested to capture CHI capabilities in an acquiring organisation. The framework is tested for its fitness through structural equation modeling (SEM) with active participation from thirteen organizations. A case is discussed to appreciate application of the framework.

In this study, we will show that cultural factors are used to explore the different findings; it can influence the initial variables directly without mediation. We also apply an extension model to the Technology Acceptance Model - the COMPASS Acceptance Model which is very suitable for testing mobile services adoption, and may be used to define the weighing factors of mobile servicespsila life cycles in different culture contexts. Data collected from France (Paris) and China (Beijing) was tested against the research model; the results strongly support the proposed model in predicting consumer behaviours when using 3G mobile services. Several implications will help 3G players to determine efficient marketing strategies and access the potential adoption of new mobile services.

A two-phase approach to provide decision support in the design and selection of load control actions in electricity networks is described. The first phase consists in the use of a multiple objective genetic algorithm, coupled with physically-based load models, for the design and selection of a set of potential non-dominated solutions (load control actions). The second phase performs the selection of the control action, to be implemented over groups of electrical loads, based on the analysis of indifference regions associated to each alternative in a parametric diagram.
