چکیده
This paper describes a work ow speci cation language namely MFDL and the implementation of its scheduler in a distributed environment Distributed nature of the scheduling provides failure resilience and increased performance Since work ow scheduling and management is highly a ected from the way the work ow is speci ed a work ow speci cation language should be e cient to prevent the problems of complexity in work ow speci cation and di culties in debugging testing the further steps of the work ow management system development MFDL being a block structured procedural work ow speci cation language is capable of de ning a work ow in an easy comprehensible and clear way so that implementation of the scheduler is simpli ed The paper also presents task handling in the system through a CORBA compliant ORB

A Work ow Speci cation Language and its Scheduler
This paper describes a workkow speciication language, namely MFDL, and the implementation of its scheduler in a distributed environment. Distributed nature of the scheduling provides failure resilience and increased performance. Since workkow scheduling and management is highly aaected from the way the workkow is speciied, a workkow speciication language should be eecient to prevent the problem...
متن کاملAutomating Handover in Dynamic Workflow Environments
Workkow technology has been widely used in business process modelling, automation and reengineering. In order to meet the fast-changing business requirements, to remain competitive in the market, an enterprise may constantly reene the workkow models of its business processes. The most challenging issue in evolution of a workkow model is the handover of its running instances from the old speciic...
متن کاملWorkflow Process Engine Interface External Workflow Engines
We introduce the ActivityFlow speciication language for in-cremental speciication and exible coordination of workkow activities. The most interesting features of the ActivityFlow speciication language include (1) a collection of speciication mechanisms, which provides a workkow designer with a uniform workkow speciication interface to describe diierent types (i.e., ad-hoc, administrative, or pr...
متن کاملConceptual Modeling of Workflows
Workkow management is emerging as a challenging area for databases, stressing database technology beyond its current capabilities. Workkow management systems need to be more integrated with data management technology, in particular as it concerns the access to external databases. Thus, a convergence between workkow management and databases is occurring. In order to make such convergence eeectiv...
متن کاملSpecifying Complex Process Control Aspects in Workflows for Exception Handling
Contemporary speciication languages of workkow management systems focus on capturing process execution semantics. Constructs are ooered that allow the speciication of sequential execution, iteration, choice, parallelism and synchronisation. While in workkow modelling it is absolutely imperative that exceptions are dealt with properly, virtually no support for the speci-cation of exception handl...
