The use of freely available online data is rapidly increasing, as companies have detected the possibilities and value these in their businesses. In particular, from social media are seen interesting they can, when properly treated, assist achieving customer insight into business decision making. However, unstructured uncertain nature this kind big presents a new challenge: how to evaluate quality manage within architecture? This paper contributes addressing challenge by introducing...

Emerging opportunities for open data based business have been recognized around the world. Open can provide new actors that data, consume and develop innovative services applications data. requires models a collaborative environment—called an ecosystem—to support businesses on services, applications. This paper outlines ecosystem (ODE) from viewpoint then defines requirements of such ecosystem. The outline are state-of-the-art knowledge explored literature state practice data-based in...

Energy markets are currently evolving due to the rapid digitalization, increasing amount of renewable energy sources, and technology development. Market actors being forced adapt their business models these changes or find new opportunities. In our earlier work, change scenarios were identified that reflect future potential Finnish companies in domain particularly with respect demand flexibility, actor roles, consumer services novel activities a kind market. The purpose this paper is examine...

A digital service ecosystem enables value creation and the co-development of services in a network under common regulation. The members are able to focus on their core competences can strengthen forces by co-operating; yet remaining act independently. However, due regulated environment, elements—i.e. members, capabilities, infrastructure existing assets—have an influence engineering, especially requirements engineering phase. main contribution this paper is describe how specify ecosystem. To...

An increasing amount of today's software systems is developed by dynamically composing available atomic services to form a single service that responds consumers' demand. These composite are distributed across the network, adapted during run-time, and still required work correctly be on The development these kinds modern requires new modeling analysis methods techniques enable reliability run-time. In this paper, we define phases design execution achieve reliable service. described in...

The opportunities of open data have been recently recognized among companies in different domains. Digital service providers increasingly interested the possibilities innovating new ideas and services around data. ecosystems provide several advantages for developers, enabling co-innovation co-creation ecosystem members utilizing sharing common assets knowledge. utilization digital requires innovation practices, development models, a collaboration environment. These can be provided by...

The use of Open Source Components (OSCs) is rapidly increasing in software systems. One the biggest obstacles for OSCs fact that integrators can not be sure quality components. Thus, it responsibility to perform evaluation. When building products using OSCs, should have a clear method and tools facilitate automate evaluation work. Our contribution tooling trustworthiness testing OSCs. provides guidelines assist their own development environment. assists technical evaluation, containing...

Now-a-days o pen data is in high demand worldwide due to the possibility of creating innovative digital services and applications around open data. This paper discusses from business perspective; about status information usage companies motivation, opportunities obstacles that relate based business. We carried out 11 interviews with company representatives receive up-to-date directly industry study estimate how far current It seems enables new for actors providing consuming but also requires...

As the number of embedded systems in everyday usage has been increasing at an enormous rate recently, demand for reliable and readily available is continuously growing. Problems reliability availability are typically detected after system implementation, when fault correction modifications difficult expensive to implement. This why a new method developed predicting already from architectural models. However, be beneficial development, prediction should enable quick, easy repeatable quality...

Reliability-aware software architecture development has recently been gaining growing attention among architects. This paper tackles the issue by introducing an ontology-based approach, called OntoArch, which is characterized by: 1) integration of reliability engineering and design; 2) targeting reliability-aware development; 3) OntoArch ontology in context design engineering. The approach validated applying to a PIR (Personal Information Repository) system architecture.

The EU has several directives aiming toward carbon neutrality and is attempting to promote encourage individual electricity consumers participate in this endeavor. key idea behind consumer awakening activation push become aware of their consumption behavior. purpose paper was examine the current behavior Finnish intention support goals through energy efficient consumption. aim reveal how far people from tackle climate change. To reach goal, a qualitative research method applied evaluate...

The ability to shift energy consumption a time when lot of is available supports the integration renewable sources. Services that intend do this automatically are currently emerging in markets. These kinds flexibility services targeted as smart household consumers, promising them cost savings, optimal living conditions, and other benefits. purpose paper examine current demand offering these Finland. We performed an extensive consumer survey untangle consumers' potential, motivation,...
