Simulation models are becoming an increasingly popular tool for the analysis and optimization of complex real systems in different fields. Finding an optimal system design requires performing a large parameter sweep. In this paper, we present the design of SOF (Simulation Optimization and exploration Framework on the cloud), a framework which exploits the computing power of a cloud computational environment...

Organizations now resort to service-orientation as it enables them to quickly create and offer new business services (BSs) or optimize existing ones. In many cases, organizations must cooperate to offer such services so as to concentrate only on their core business. An initial phase to the design of a novel BS concerns the determination of the BS's functional and non-functional requirements. The respective...
This paper presents a methodology for composing a SOA service chain by evaluating and selecting a service for the purpose of business result optimization. The methodology requires the business performance model for applied services to measure the value produced by services in a specific business context. Understanding the business characteristics where services are applied is a prerequisite for evaluating...

This paper presents an integrated intelligent system being capable of automatically estimating and updating a large-size matrix. In the theoretical economics, the input-output model of economics uses a matrix representation of a nation's (or a region's) economy to predict the effect of changes in one industry on others and by consumers, government, and foreign suppliers on the economy. The system...
The increasing ubiquity of mobile embedded systems has been matched by the evolution of a variety of wireless network standards and technologies. The major constraints of wireless embedded systems are limitations of communication bandwidth, processing capabilities, and battery power. Remote wireless embedded systems often act as sensors, which provide data to a certain community. The exchange of data...
This is an introduction to the proceedings of the MWS 2007 workshop held at EDOC 2007. It first explains the motivation for and background of the workshop. Then, it contains a short description of the keynote, each long and short peer-reviewed paper, and the discussion session "impact of various execution environments on middleware for web services". After the closing statements, MWS 2007...
