Process-Centered Software Engineering Environments (PSEEs) deal with activities that demand specialized personnel and limited resources. Characteristics about required resources and people (and their dynamic availability) are used by software process instantiation phase to define process allocation strategies. However, most of existing PSEEs do not allow precise resource specification, and the instantiation is often based on the knowledge of a process designer, mostly without automated support. Thus, process managers must make all major decisions based on their individual insights and experience: this constitutes a major obstacle for resource allocation analysis and optimization in process systems and can influence project management and overall software quality. This paper proposes Instantiation Policies as a compact formalism, integrated to a process modeling language, to allow user-defined reusable management strategies for resource instantiation. Through the proposed language it is possible to plan or automate allocation depending on process and organization current situation. This paper discusses the motivations for this solution, shows the proposed meta-model, language and some application examples for this approach.
Este artigo apresenta e discute a modelagem e gerência de recursos de apoio em um ambiente de gerência de processos de software (PSEE). Os PSEEs, tal como os sistemas de Workflow, coordenam tarefas que requerem recursos limitados. Todavia, a maioria dos modelos não permite a especificação precisa desses recursos, o que impede a análise e otimização da sua utilização. A abordagem APSEE é apresentada como contribuição neste tópico, através de um modelo de recursos, da integração do modelo a um PSEE existente e de um mecanismo de auxílio à instanciação de recursos para atividades de um processo. O artigo também discute aspectos da implementação do modelo proposto, além de comparações com trabalhos relacionados.
