Generation companies operating in a competitive market face price and volume risks that affect their return. Being able to identify and quantify these risks for each type of generation asset and how they interact is fundamental when making investment decisions regarding the portfolio of generation assets. This paper proposes a set of tools to support the decision of investment in a portfolio of generation assets, according to portfolio theory. The concept of efficient frontier of risk and return as set in that theory is used to find optimal generation portfolios. Gas-, coal- and fuel- fired as well as hydroelectric and on shore wind power plants are considered. Risk and return are estimated through Monte Carlo simulation of free cash flows. For that effect, exogenous variables such as fuel, electricity and emission prices, wind speeds and water inflows are modeled with stochastic processes. Investment decisions are studied for two perspectives: fixed capital costs allocation and installed capacity allocation. Considering constraints for risk, return and capacity over the efficient Pareto frontier, decisions of buy and/or sell required to achieve optimal generation portfolios are pointed out.

The core functions of engineering management involve forecasting and planning, organizing, directing, coordinating, controlling, communicating and motivating. Underlying to an effective and efficient realization of such so- called processing elements of management is the notion of collaboration. Collaboration is the process of shared creation through which a group of entities enhances capabilities of each other. Thus, mastering collaboration in its many forms is key for the engineer manager successful professional engagement. Collaboration, enabled by technology, can be seen at least in two dimensions: Interoperability, for businesses to work together seamlessly, by enabling interactions with each other across enterprise boundaries; and Collaborative Working, for ensuring that employees have at their fingertips the information, applications, services needed for team-work. By combining both, the first capturing the systems perspective and former addressing human interaction aspects, one is able to grasp the competences and skills of Collaboration. This paper presents a dynamic curriculum for advanced training on Collaboration, by integrating Interoperability and Collaborative Working paradigms, organized in three training curricula following the typical career path of engineers. Equipped with such abilities, supported by traditional components of management, professionals can drive improved management of engineering and engineering processes leading to efficiency, differentiation and innovation towards growth.

Our purpose with this paper is to report what we have been researching in the field of project management scope design. We address scope design as a process of change in a network. A process of change of settings where actor-networks evolve and dissolve, grabbing new actors and providing alignments. This approach in project scope management facilitates richer possibilities for capturing requirements, intensifies identification of tensions among actors (hybrid actors as stakeholders) and contributes to adapt project scope to context changing. This view is explored trough three short engineering stories.

Information systems used at higher education institution support essentially academic management processes like student's registration, student's management, student's marks, among others. These systems do not permit the closely monitoring of student's academic activities, the evaluation of their academic success and the support of academic activities concerning with teaching and tutoring. On the other hand, it is largely accepted that there exists a strong correlation between the closely monitoring of the students' activities and the scholar success promotion. To support the teaching and tutoring processes it is essential to acquire knowledge about the students. This knowledge will allow the adoption of adequate and effective actions/decisions in order to closely follow the students' activities. In order to be possible such procedures, this paper proposes a student relationship management (SRM) system. This system will support the SRM concept and the SRM practice and will be implemented using the concepts and the technological infrastructure that supports the Business Intelligence systems. The concept, practice and architecture of the SRM system are presented in this paper and its main goal is to provide a technological tool that support higher education institution in the acquisition of knowledge that is essential to the decision- making process.

This paper investigates whether Foreign Direct Investment (FDI) and investment in Information and Communication Technologies (ICT) advances the development of technological entrepreneurship. We propose that the combination of inward FDI with investment in ICT is an important driver of technologically-oriented entrepreneurial activity. Under a feedback causality context, a Cointegrated Vector Autoregressive approach is used to examine the 'pull' effect of ICT and the 'push' effect of FDI. On the one hand, ICT 'pulls' inward FDI; on the other hand, FDI 'pushes' investment in ICT. Under a neo-Schumpeterian approach, the triple-mix among technological entrepreneurship, inward FDI, and ICT drives creative destruction through the creation of further SMEs, thus revitalizing the entrepreneurial innovative capability of nations.

This paper presents a Geographical Information System (GIS) based risk assessment model for road transportation of hazardous materials (hazmat). Existing and proposed risk models are applied to truck shipments of hazmat through the road network of Istanbul. Our empirical analysis on the Istanbul road network points out that different risk models usually select different routes between a given origin-destination pair. In this study, we propose a new risk assessment model named as ldquotime-based risk modelrdquo for hazmat transportation. We speculate that the proposed model is the most suitable one for the city of Istanbul and alike.

Construction industry involves several players in a same project. Defining and coordinating such players and their activities is a very complex task. Hence, an information system capable of aggregate and display the relevant information, in the right time, is an extraordinary tool to help the construction site managers. There is a diversity of software available in the market that is very powerful in many specialised areas, but lacks the supply chain management overview. An integrated web portal to assist the managers in their daily tasks and simultaneously effectively control the entirely construction project is a partial result of a research project in a Portuguese construction company. This paper intends to show the main developments and preliminary conclusions in the implementation of this web portal to assist the logistics of construction projects.
