Workflow simulation is an effective approach to investigate dynamic workflow scheduling strategies and evaluate system performance. In this paper we report on a series of performance tests run on our workflow scheduling and quality measurement system. Traditional calculations for workflow scheduling strategies focus only on machine service duration; however, in some contexts the variation of transport...
Workflow simulation is an effective approach to investigate dynamic workflow scheduling and evaluate system performance. In this paper we report on a test management system for the evaluation of a range of workflow scheduling strategies based on multi-agent negotiation, where each resource agent performs local scheduling using dispatching rules. The newly developed test management system runs test...
Multi-agent systems (MAS) that link business and physical domains such as in production automation need to be reconfigured correctly and efficiently to adapt to new requirements. The standard UML-based approach only partly supports the reconfiguration process to capture agent classes and their instances, while ontologies allow modeling all aspects of MAS design in one common continuous model. In this...
The quality evaluation of open source software (OSS) products, e.g., defect estimation and prediction approaches of individual releases, gains importance with increasing OSS adoption in industry applications. Most empirical studies on the accuracy of defect prediction and software maintenance focus on product metrics as predictors that are available only when the product is finished. Only few prediction...
Open source software (OSS) solutions provide mission- critical services to industry and government organizations. However, empirical studies on OSS development practices raise concerns on risky practices such as unclear requirement elicitation, ad hoc development process, little attention to quality assurance (QA) and documentation, and poor project management. Event then the ability to produce high...
