An Intelligent System for Building Bioinformatics Workflows
2012
In this paper a new intelligent system designed to support the researcher in the development of a workflow for bio informatics experiments is presented. The proposed system is capable to suggest one or more strategies in order to resolve the selected problem and to support the user in the assembly of a workflow for complex experiments, using a a Knowledge base, representing the expertise about the application domain, and a Rule-Based system for decision-making activity. Moreover, the system can represent this workflow at different abstraction layers, freeing the user from implementation details and assisting him in the correct configuration of the algorithms. A sample workflow for protein c…
Reusability and modularity in transactional workflows
1997
Abstract Workflow management techniques have become an intensive area of research in information systems. In large scale workflow systems modularity and reusability of existing task structures with context dependent (parameterized) task execution are essential components of a successful application. In this paper we study the issues related to management of modular transactional workflows, i.e., workflows that reuse component tasks and thus avoid redundancy in design. The notion of parameterized transactional properties of workflow tasks is introduced and analyzed, and the underlying architectural issues are discussed.
Knowledge organization for modelling workflows in Taverna environment
2014
Today Workflow Management Systems (WFMS), like Taverna and Kepler, have a very important place in the everyday work of the scientist. These tools support the access to computational resources and act as interface for building complex data processing chains. The next step is to support decisions of the researcher on autonomously developing workflow parts guided by requirements of the scientist while she/he is working on the high-level goal of the experiment. To this aim, it is necessary an ontology to store the knowledge related to the experiments and tools used, and to make this knowledge available not only to the scientist, but also to a suitable artificial intelligent system. In this pape…
Workflow-Based Decision Support for Failure Mode and Effects Analysis
2010
Abstract To achieve high quality designs, processes, and services that meet or exceed industry standards, it is crucial to identify all potential failures throughout a system and work to minimize or prevent their occurrence or effects. This paper presents an innovative approach to Failure Mode and Effects Analysis (FMEA) that uses a Decision Support System (DSS) for supporting the FMEA processes. The DSS is powered by a workflow engine that guides the users through the processes by considering standard work templates or previous similar cases. It is also built as a framework for decision support tools so, beside its default one, different FMEA work instruments can be plugged-in and used thr…
