An approach to assess collaboration readiness

Abstract: The level of readiness of an organisation to join a collaborative process depends on ‘hard’ factors such as competency fitness or technological compatibility, but also on several other factors of a ‘soft’ nature such as an organisation's character, willingness to collaborate, or affectivity/empathy relationships. Considering these aspects, a modelling approach to assess how prepared an enterprise is to join a collaborative network is proposed. The approach is based on the notion of ‘character’ of the organisation, addressing behavioural aspects regarding collaboration. The distinction between collaboration readiness and preparedness is established. In order to deal with the incompleteness of information and uncertainties associated to the readiness assessment process, it is proposed to use belief networks, which allow performing inference concerning behavioural characteristics of organisations. The approach is then extended in order to handle decision making under situations characterised by uncertainty. ...

Care services ecosystem for ambient assisted living

Abstract: Effective provision of care and assistance services in ambient assisted living requires the involvement and collaboration of multiple stakeholders. To support such collaboration, the development of an ecosystem of products and services for active ageing plays an important role. This article introduces a conceptual architecture that supports such care ecosystem. In order to facilitate understanding and better interrelate concepts, a 3-layered model is adopted: Infrastructure layer, Care and assistance services layer and Ambient Assisted Living ecosystem layer. A holistic perspective of ambient assisted living, namely considering four important life settings is adopted: (1) independent living; (2) health and care in life; (3) occupation in life and (4) recreation in life. The proposed architecture is designed in the context of a national Portuguese project and in accordance with the findings of a large European road mapping initiative on ICT and ageing.

A comprehensive research roadmap for ICT and ageing

Abstract: Ageing societies face tough challenges namely in terms of the pressure on their healthcare and social security systems, which makes it urgent to find new models to accommodate current demographic trends. A possible answer to this challenge may come from new integrated and technology-supported services. In this direction, a European roadmapping initiative has addressed the implementation of a new vision for technological support to ageing. The main findings of this initiative are presented as a roadmap, which synthesizes the contribution of a large number of stakeholders coming from different backgrounds.

Extended competencies model for collaborative networks

Abstract: One of the steps usually undertaken in the formation of partnerships is the assessment of organisations’ competencies. The typical notion of competencies, which have a functional or technical nature and provide specific outcomes, refers, in fact, to what can be considered as hard competencies. However, the very act of collaboration has its specific requirements, for which the involved organisations must be apt to exercise other types of competencies that affect their own performance and the success of the partnership. These competencies are more of a behavioural nature, and can be named as soft competencies. This study aims at addressing the effects of the soft competencies on the performance of the hard ones. An extended competencies model is thus proposed, allowing the construction of adjusted competencies profiles, in which the competency levels are dynamically determined according to the requirements of collaboration opportunities. The idea of competencies fitness arises from this adjustment, allowing...

A multi-agent based platform for virtual communities in elderly care

Abstract: The growing numbers of elderly population impose an urgent need to develop new approaches to care provision. The convergence of a number of technologies such as multi-agent systems, federated information management, safe communications, hypermedia interfaces, rich sensorial environments, increased intelligence of home appliances, and collaborative virtual environments, represents an important enabling factor for the design and development of virtual elderly support community environments. In this paper, a platform based on mobile agents combined with federated information management mechanisms is introduced as a flexible infrastructure on top of which specialized care services can be built.

Goods and services.

Abstract: A good is something you buy and consume. Goods are things that you can keep, eat, or use. If you go to the store and buy an apple, you get to keep the apple and take it home with you, so it is a good. A service is something that someone does for you. When you buy a service, you hire people to perform work. You are not buying something you can touch or hold. If your car is broken, you might hire someone to fix it. You are paying for a service.

A Review and State of Art of Internet of Things (IoT)

Abstract: The Internet of Things (IoT) is basically like a system for connecting computer devices, mechanical and digital machines, objects, or individuals provided with the unique system (UIDs) and without transfer to transmit data over an ability human-to-human or computer-to-human relation. Another thing on the internet is that the items in the IoT are like a connected manner with humans and computers to which internet protocol addresses can be assigned and which can transfer data over the network or another man-made object. In this paper, we describe the utilization of IoT in the cloud, fog, IoT technologies with applications and security. Specifically, we provide IoT architecture for design and development with sensors in 6G. Finally, we discuss the current research, solutions, and present open issues of future research in IoT.

Internet of things (IoT) applications for elderly care: a reflective review.

Abstract: Increasing in elderly population put extra pressure on healthcare systems globally in terms of operational costs and resources. To minimize this pressure and provide efficient healthcare services, the application of the Internet of Things (IoT) and wearable technology could be promising. These technologies have the potential to improve the quality of life of the elderly population while reducing strain on healthcare systems and minimizing their operational cost. Although IoT and wearable applications for elderly healthcare purposes were reviewed previously, there is a further need to summarize their current applications in this fast-developing area. This paper provides a comprehensive overview of IoT and wearable technologies' applications including the types of data collected and the types of devices for elderly healthcare. This paper provides insights into existing areas of IoT/wearable applications while presenting new research opportunities in emerging areas of applications, such as robotic technology and integrated applications. The analysis in this paper could be useful to healthcare solution designers and developers in defining technology supported futuristic healthcare strategies to serve elderly people and increasing their quality of life.

Inter-firm collaborations and supply chain coordination: review of key elements and case study

Abstract: Considering the effects of globalisation, the increase of production and energy costs, and the introduction of advanced technologies, companies need to change their way of doing business if they want to stay competitive. One way of doing this is to establish collaborations with suppliers, distributors and retailers, in order to exchange products efficiently and create value for customers. Nevertheless, the structure of the collaboration must be designed carefully and some coordination mechanisms must be implemented to support this way of doing business. In this article, we first analyse: why companies work together, how they should build their partnership, and which strategies they can implement to facilitate coordination of supply chain activities. We then report a case study of collaboration in the forest industry that shows the benefits of implementing coordination mechanisms as well as the necessity of using incentives to better share these benefits.

Readiness assessment of collaborative networked organisations for integrated product and service delivery

Abstract: More and more firms are entering into alliances and coalitions to deliver competitive customer solutions, and there is a need to establish a common and recognised methodology in order to evaluate and qualify the impact of such company partnering on collaborative networks. These measures are necessary for informing decisions to admit/omit partners, for the delivery of integrated products and services, i.e. a product-service system, and for enhancing operational efficiency and competitiveness in the rapidly changing and dynamic global environment. In this article, a conceptual model is proposed for assessing the readiness of collaborative networked organisations for product-service system delivery. The model consists of a structural assessment of collaborative network topologies and densities, and a behavioural assessment of partner delivery competences and performance. Based on these concepts, an assessment process model was developed and used in case studies across industrials, consumer goods, health care...
