Analysis and control of complex collaborative design systems

This paper presents a novel method for modelling the complexity of collaborative design systems based on its analysis and proposes a solution to reducing complexity and improving performance of such systems. The interaction and interfacing properties among many components of a complex design system are analysed from different viewpoints and then a complexity model for collaborative design is established accordingly. In order to simplify complexity and improve performance of collaborative design, a general solution of decomposing a whole system into sub-systems and using unified interface mechanism between them has been proposed. This proposed solution has been tested with a case study. It has been shown that the proposed solution is meaningful and practical

The Trans-Pacific Partnership (TPP): In Brief

The Trans-Pacific Partnership (TPP) is a proposed free trade agreement (FTA) among 12 Asia-Pacific countries, with both economic and strategic significance for the United States. If approved, it would be the largest FTA in which the United States participates. The 12 countries announced the conclusion of the TPP negotiations on October 5, 2015, after several years of ongoing talks. The President released the text of the agreement and notified Congress of his intent to sign on November 5, 2015. Congress would need to pass implementing legislation for a final TPP agreement to enter into force for the United States. Such legislation would be eligible to receive expedited legislative consideration under the recent grant of Trade Promotion Authority (TPA), P.L. 114-26, if Congress determines the Administration has advanced the TPA negotiating objectives, and met various notification and consultation requirements. TPP negotiating parties include Australia, Brunei, Canada, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore, the United States, and Vietnam. Through the TPP, the participating countries seek to liberalize trade and investment and establish new rules and disciplines in the region beyond what exists in the World Trade Organization (WTO). The FTA is envisioned as a living agreement that will be open to future members and may become a vehicle to advance a wider Asia-Pacific free trade area. It is a U.S. policy response to the rapidly increasing economic and strategic linkages among Asian-Pacific nations and has become the economic centerpiece of the Administration’s “rebalance” to the region. The TPP has slowly evolved from a more limited agreement among four countries concluded in 2006 into the current 12-country FTA agreement, with the United States joining the negotiations in 2008. Japan, the most recent country to participate, joined the negotiations in 2013. This significantly increased the potential economic significance of the agreement to the United States, because Japan is the largest economy and trading partner without an existing U.S. FTA among TPP negotiating partners (thus having greater scope for trade liberalization with the United States). The United States already has FTAs with 6 of the 11 other countries participating. Malaysia and Vietnam also stand out among the TPP countries without existing U.S. FTAs, given the rapid growth in U.S. trade with the two nations over the past three decades and substantial presence of state-owned enterprises (SOEs) that will be affected by the TPP’s SOE provisions. Views on the potential impact of the agreement vary. Proponents argue that the TPP has the opportunity to boost economic growth and jobs through expanded trade and investment opportunities with negotiating partners that currently make up 37% of total U.S. goods and services trade, involves writing new trade rules and disciplines, and deepening U.S. trade and investment integration in what many see as the world’s most economically vibrant region. The agreement would eventually eliminate all tariffs on manufactured products and most agricultural goods. It also includes new trade disciplines on issues such as digital trade barriers, state-owned enterprises (SOEs), and regulatory coherence, among other provisions. Opponents voice concerns over potential job loss and competition in import-sensitive industries, and how a TPP agreement might limit U.S. ability to regulate in areas such as health, food safety, and the environment, among other concerns. The Obama Administration, joined by many analysts as well as many policymakers in the region, has argued that the strategic value of a potential TPP agreement parallels its economic value, contending that the agreement would strengthen U.S. allies and partners and reaffirm U.S. economic leadership in the region. The President has repeatedly highlighted the importance of maintaining U.S. leadership in crafting global trade rules, notably with reference to potentially alternative Chinese initiatives. China is not a party to the TPP. Others argue that past trade pacts have had a limited impact on broad foreign policy dynamics

Critical success factors for e-tendering implementation in construction collaborative environments : people and process issues

The construction industry is increasingly engulfed by globalisation where clients, business partners and customers are found in virtually every corner of the world. Communicating, reaching and supporting them are no longer optional but are imperative for continued business growth and success. A key component of enterprise communication reach is collaborative environments (for the construction industry) which allows customers, suppliers, partners and other project team members secure access to project information, products or services they need at any given moment. Implementation of the stated critical success factors of the project is essential to ensure optimal performance and benefits from the system to all parties involved. This paper presents critical success factors for the implementation of e-tendering in collaborative environments with particular considerations given to the people issues and process factors

MOSAIC roadmap for mobile collaborative work related to health and wellbeing.

The objective of the MOSAIC project is to accelerate innovation in Mobile Worker Support Environments. For that purpose MOSAIC develops visions and illustrative scenarios for future collaborative workspaces involving mobile and location-aware working. Analysis of the scenarios is input to the process of road mapping with the purpose of developing strategies for R&D leading to deployment of innovative mobile work technologies and applications across different domains. One of the application domains where MOSAIC is active is health and wellbeing. This paper builds on another paper submitted to this same conference, which presents and discusses health care and wellbeing specific scenarios. The aim is to present an early form of a roadmap for validation

Electronic negotiation and security of information exchanged in e-commerce

In settings such as electronic markets where trading partners have conflicting interests and a desire to cooperate, mobile agent mediated negotiation have become very popular. However, agent-based negotiation in electronic commerce involves the exchange of critical and sensitive data that must be highly safeguarded. Therefore, in order to give benefits of quick and safe trading to the trading partners, an approach that secures the information exchanged between the mobile agents during e-Commerce negotiations is needed. To this end, we discuss an approach that we refer to as Multi-Agent Security NEgotiation Protocol (MASNEP). To show that MASNEP protocol is free of attacks and thus the information exchanged throughout electronic negotiation is truly secured, we provide a formal proof on the correctness of the MASNEP.<br /

CITIZENS AND INSTITUTIONS BETWEEN COMPUTERS AND INTERNET - AN EMPYRICAL EVIDENCE FROM THE ITALIAN CASE

The diffusion of ICT technologies that generated the Internet phenomenon, is responsible of the world-wide incredible expectation level related to its high potential contribution to problem solution in many socio-economic sectors. In facts, the contribution of ICT in some sectors, as organizations management (public or private, profit or no-profit), was undoubtedly highly effective. The interaction between citizens and institutions is also considered extremely interesting, as the specific funds appropriation since the end of 90es of European Union on these topics can demonstrate. This wide interest caused the expectation of a remarkable services improvement, but the obtained results doesn’t seem as much satisfactory. This international and European scenario had a meaningful reflex also in Italian case, because the lack of information flows between Institutions and citizens in our country is always strongly perceived as critical point. In a former study of 1998 (Tesauro, Campisi), some institutional web sites was included in a wider study sample about the usage of internet communications, reaching unflattering results. Nevertheless, some recent “accidents” in citizen-institution relationships, widely reported by mass media and strictly related to computer technologies, suggest remarkable doubts about the usage of these technologies. This happen in spite of the creation of a specific Ministry in Italy and five years later the cited study, an incredible amount of time in terms of evolutionary dynamic of virtual environment). So, the main objective of this contribution is to show a scenario of citizen-institution relation via Internet in Italy at different scales (national, regional and local), identifying strength or weak points not only from users viewpoint and trying to underline the difficulties inherited from a poor usage of actual computer knowledge.
