As mobility permeates into todays computing and communication arena, we envision application infrastructures that will increasingly rely on mobile technologies. Traditional database applications and information service applications will need to integrate mobile entities: people and computers. In this paper, we develop a distributed database framework for mobile environments. A key requirement i...

Todays Web Applications are complex distributed applications, that deploy their functionality to the World Wide Web. In many cases Web Applications have been developed by using an adhoc and unsystematic development process. As a conesquence these applications have a high probability of failure during operation. In order to develop high quality Web Application both the development process and th...

Recently, approaches that combine contexts and ontologies taking advantages of their strengths have been developed. Each of them solves different problems from different perspectives. The objective of this paper is to present problems that are not solved up to date as well as to introduce a conceptual proposal. To this aim, we base our analysis on a collaborative B2B scenario that is relevant f...

Firms no longer compete as autonomous entities and prefer to join in a supply chain alliance to take advantage of highly competitive business situation. Supply chain coordination has a great impact on strategic partnering and success of a firm in competitive business environment. In this paper, we propose a system dynamics simulation model for strategic partner selection in supply chain. Our mo...

In this article we describe our research eeorts in coping with a trade-oo that can be often found in the control and optimization of todays business processes. Though centralized control may achieve better results in controlling the system behavior, there are usually social, technical and security constraints on applying centralized control. Distributed control on the other hand may cope with t...
