The common access to the broadband Internet allows small and medium enterprises (SME) simpler participation in various supply chains [3]. However the main problem still is lack of consistency between processes which are undertaken by various supply chain participants. The aim of this paper is to propose the concept of broader cooperation between manufacturing companies based on semantic web and multi-agent system. The background of this paper refers to previous experiences of the authors by implementation of the CORELOG project. It promotes cooperation in logistics services among manufacturing companies located in the Bologna metropolitan area in order to increase companies' competitiveness as well as environmental sustainability through the rationalization of the logistics processes. The application of semantic web and multi-agent system in the above mentioned project allows the efficient automatic data collection about logistics services providers and their resources, as presented in the Internet.

An ambient agent system is presented estimating a human's dynamics of desiring and being tempted. The agent is equipped with a dynamical model of the human's processes which describes how a desire relates to responses in the form of being prepared for certain actions, which in turn relate to feelings which can be biased, due to experiences in the past. It is shown how by use of this dynamical model, the ambient agent is able to predict and assess a human's desire state, and his or her preparation for certain actions, and use this assessment to suggest alternatives to avoid falling for certain temptations.

The dimensioning of multistage machining processes consisting of roughing and finishing operations requires a linked consideration of the transformation of target values over all stages. The analytical hierarchy approach (AHP) is used to solve the arising multi-criteria problem regarding technologic and economic criteria based on empirical process models. Therefore, the presented concept includes existing interdependencies by the means of transfer values leading to an effective and comprehensible dimensioning of multistage machining processes. The concept is implemented into a software prototype programmed in JAVA. Individual process stages, targets and criteria can be implemented by the decision maker. The resulting overall target function consists of preference multipliers and standardized sub-criteria functions weighted by AHP. High values of the target-function point out combinations of process parameters for each stage that yield to a multi-criteria optimized multistage process. The concept is exemplary illustrated by means of a multistage grinding operation for 4-cylinder crankshafts.

In a recent paper artificial ants were applied to solve the Undirected Rural Postman Problem. The problem was transformed into a Traveling Salesman Problem and artificial ants were applied to this new problem. This paper applies another transformation, proposed by Pearn et al, which also transforms the arc-routing problem into a node routing problem.

Specification and Description Language (SDL) is an object-oriented and formal standardized language for the specification of complex, event-driven, real-time and interactive applications involving many concurrent activities that communicate using discrete signals. Using SDL formal model for system specification we bridge the gap between ideas in our minds and the actual implementation of the system. In this paper we propose the ontology for the basic SDL elements. We also propose a formal framework of SDL Markup Language as a medium for translating SDL model to SDL ontology.

Virtual design ergonomic evaluation is useful at early design stage where the physical design mock up is not available but human-centred design must be considered. The interactive virtual ergonomics evaluation approach integrates a digital human model (DHM) with a product's digital mock up to form a DHM-included virtual environment (VE). The DHM is interactively puppeteered by a human player who wears motion capture devices. Posture data recorded by the motion capture devices are sent to ergonomics programs for evaluation. The DHM-included VE developed by previous research suffers from two problems. First, the DHM can only touch or reach the virtual objects but can not grab nor manipulate them. As such the range of posture data that could be acquired is limited. Secondly, the domain experts, who are usually non VR experts, have to resort to VR engineers to specify the interactions between DHM and virtual objects, which make the virtual evaluation process inconvenient and inefficient. This paper discusses an interactive VE in which the DHM could grab objects and manipulate them. A two-level Petri-net (PN) is proposed as a high-level, graphical representation that allows domain experts to quickly and easily define the interactions between the DHM and the virtual object. The first-level PN monitors the object-grabbing status whereas the second-level PN monitors the hand-grabbing status and hand coordination. If the object-grabbing status or the hand-grabbing status is wrong, the PN will stop the posture data recording process, reset the object to its original position, and notice the human player to re-do the operation so that correct posture data could be acquired. A case study is presented in which the proposed method is applied to generate an interactive VE to acquire posture data for evaluating ergonomics problems associated in operating and maintaining a control console in a ship control room.

In this paper we present an agent-based add-on for the Social-Net Tourism Recommender System that uses information extraction and natural language processing techniques in order to automatically extract and classify information from the Web. Its goal is to maintain the system updated and obtain information about third parties services that are not offered by service providers inside the system.

In this work we present a multiagent system to draw up an optimum portfolio. By using a distributed architecture, the agents are trained to follow different investing strategies in order to optimize their portfolios to automate the one year forecast of a portfolio's payoff and risk. The system allows to adopt a strategy that ensures a high rate of return at a minimum risk. The use of neural networks provides an interesting alternative decisions to the statistical classifier. With a modular agent composed by a few trained neural networks, the system makes investment decisions according to the assigned investment strategy and the behavior of the prices in a one-year period. The agent can take a decision on the purchase or sale of a given asset.

Technology Innovation has become the principal method for enterprises to survive in the competitive economic environment. This paper, by using the Product Life Cycle Theory, discusses the different technology innovation patterns that enterprises can adopt at different stages of the product life cycle. The paper thus develops a number of technology innovation strategies under those different patterns and further summarizes the choice factors that influence technology innovation patterns.

User preference is often a source of uncertainty in web search. We propose an order-oriented description logic suited especially to represent user preference. Concepts are interpreted as preorders of individuals from the domain. We redefine reasoning tasks to reflect order-oriented approach and we present an algorithm for order instance problem in description logic without aggregation. Furthermore, we describe top-k retrieval which allows us to find the best objects with respect to user preference concepts.
