Applying Activity Patterns for Developing an Intelligent Process Modeling Tool

Due to their high level of abstraction and their reusability, workflow patterns are increasingly attracting the interest of both BPM researchers and BPM tool vendors. Frequently, process models can be assembled out of a set of recurrent business functions (e.g., task execution request, approval, notification), each of them having generic semantics that can be described as activity pattern. To our best knowledge, so far, there has been no extensive work implementing such activity patterns in a process modeling tool. In this paper we present an approach for modeling business processes and workflows. It is based on a suite which, when being implemented in a process modeling tool, allows to design business processes based on well-defined (process) activity patterns. Our suite further provides support for analysing and verifying certain properties of the composed process models (e.g., absence of deadlocks and livelocks). Finally, our approach considers both business processes designed from scratch and processes extracted from legacy systems

Inventing Less, Reusing More and Adding Intelligence to Business Process Modeling

Recently, a variety of workflow patterns has been proposed focusing on specific aspects like control flow, data flow, and resource assignments. Though these patterns are relevant for implementing Business Process Modeling (BPM) tools and for evaluating the expressiveness of BPM languages, they do not contribute to reduce redundant specifications of recurrent business functions when modeling business processes. Furthermore, contemporary BPM tools do not support process designers in defining, querying, and reusing activity patterns as building blocks for process modeling. Related to these problems this paper proposes a set of activity patterns, evidences their practical relevance, and introduces a BPM tool for the modeling of business processes based on the reuse of these activity patterns. Altogether our approach fosters reuse of business functions specifications and helps to improve the quality and comparability of business process models

0021/2009 - Metodologia de identificação de serviços a partir da modelagem de processos de negócio

A arquitetura orientada a serviços (SOA – Service Oriented Architecture) apresenta-se como sendo mais flexível e capaz de suportar serviços independentes de plataforma e protocolo em um ambiente distribuído. Neste trabalho analisamos modelos de ciclos de vida para gestão de serviços e metodologias para identificação de serviços existentes na literatura. Em seguida, propomos um método para identificação de serviços a partir da modelagem de processos de negócio no contexto de um ciclo de vida. O método proposto é baseado em heurísticas, as quais direcionam a identificação de serviços a partir de modelos de processos de negócio
