This paper describes the procedures used during the planning of a material delivery system for the manufacturing lines of an electronic company. The paper describes the simulation experiments of a material delivery system for the manufacturing lines, using a logistic train. The main objective of this study is to make simulation experiments, regarding different amounts of equipment and logistic train programming methods, in order to identify and to propose changes that may lead to greater efficiency and precision of the logistic train functioning. The developed models were implemented with Arena simulation software. Experimental results are presented. Conclusions are discussed.

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.

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.

Climate change and the continuous need for energy has influenced the developing of bioenergy technologies. Wood pellet heating is a rather new potential for sustaining heating technology of domestic households. However, adopting pellet heating systems has been rather slow in Finland. The diffusion and adoption of the pellet heating system has been studied earlier but only scant attention has been given to the personal attributes in influencing adoption decisions. The main purpose of this article is to empirically study the attributes of residential customer segments. Theoretically the paper is based on the innovation decision theory and sequence of customer segments adopting technological innovations in different phases of the product life cycle. The empirical material consists of inquiries (n=154) canvassed in the Hameenlinna Housing Expo Finland in summer 2007. The results show the significance of the gender and age in adoption of pellet heating. The managerial implications and future research avenues are also discussed.

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.

By reviewing on the organizational theories and innovative theories, it presents the definition and structure of innovative organizations in knowledge-intensive business services (KIBS), and proposes the structure of innovative organization by three dimensions, namely self-management, interdependence and boundary penetrability, and the innovative performance by two dimensions, namely acquired performance and standardized performance. Then, the empirical analysis on the relationship between innovative organization and innovative performance within standardized KIBS and customized KIBS are carried out. It is found that the characteristics of innovative organizations in two kinds of KIBS are different, and the differences of innovative performance under different KIBS are also testified.

Nowadays technical excellence is not enough to inspire customers for a product. Absolute freedom from error is a basic requirement. But how can customers be rendered enthusiastic about future products? The answer to this question lies in the creation of optimal customer-specific products. Perceived quality of a product is constituted by all visual, tactile, acoustic, gustatory and olfactory impressions. Perceived quality adds customer group specific and subjective perceptible characteristics to the basic understanding of quality. Until now there is no comprehensive systematic approach to close the gap between subjective customer perception and objective product characteristics. To manage these challenges, it is necessary to change the way of thinking within the product development.

Product quality is traditionally seen as the intersection of customer requirements on the one side and the product characteristics on the other. This classical understanding of quality is insufficient to cover all entrepreneurial conditions. It needs to be enlarged by a holistic, more market oriented view. To cover all economical requirements the articulated and implicated customer demands, the defined management strategy and the actual companies' ability should be taken into account. To face these challenges a new quality management framework is required, which allows a holistic organization of the corporate quality management. The architecture of such a model should enable companies to visualize, harmonize and align their project and process landscape to increase production systems' efficiency and effectiveness. Thus, the introduced life-cycle-oriented Aachen Quality Management Model provides such a framework which allows a holistic analysis, assessment and improvement of production systems to increase productivity. The explicit consideration of the customer requirements, the corporate orientation and the corporate skills represents a paradigm shift towards other quality management models like EFQM or the ISO 9000 family.

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.
