A Dynamic Business Network is a distinct system of participants (customers, suppliers, complimentors, competitors, service providers) that use the network to achieve customer satisfaction and profitability and where participants and relationships evolve over time. However, unpredictability and rapid change in a Dynamic Business Network creates a significant challenge in implementing and supporting business application software. Traditional information systems implementation methods require an a priori design and are built for a particular purpose for use over an extended period of time. Loosely coupled business networks change interrelationships between nodes both quickly and frequently, thus providing little or no notice for planning, implementing, or changing the supporting applications. The dynamic sourcing capabilities of the emerging Web Services framework provide a key to enabling these complex eco-systems. We explore the strategic and technological dimensions of Web Services and describe how they can be used to support dynamic business networks.

Abstract. In crisis, decisions must be made in human perceptual timeframes under pressure to respond to dynamic uncertain conditions. To be effective management must have access to real time environmental data in a form that can be immediately understood and acted upon. The emerging computing model of Dynamic Data-Driven Application Systems (DDDAS) fits well in crisis situations where rapid decision-making is essential. We explore the value of a DDDAS (iRevive) in support of emergency medical treatment decisions in response to a crisis. This complex multi-layered dynamic environment both feeds and responds to an ever-changing stream of real-time data that enables coordinated decision-making by heterogeneous personnel across a wide geography at the same time.

This study aims to review current issues regarding the application of blockchain technology in health care. We illustrated the various ways in which blockchain can solve current health care issues in three main arenas: data exchange, contracts, and supply chain management. This paper presents several current and projected uses of blockchain technology in the health care industry. We predicted which of these applications are likely to be adopted quickly and provided a supply chain example of tracking the transportation of organs for transplantation.
