To demonstrate the use of our approach, we chose the JaCaMo agent framework for its inherent support of agent organisations described with the MOISE meta-model.

abstract = {Organizations willing to employ workflow technology have to be prepared to undertake a significant investment of time and effort due to the exceptional dynamic nature of the business environment. Today, it is unlikely that processes are modeled once to be repeatedly executed without any changes. Goal-oriented dynamic workflows are a promising approach to provide flexibility to the execution of business processes. Many goal-oriented frameworks exist in literature to be used for the purpose. However, modeling goals is a burden for the business analyst. This work proposes an automatic approach for extracting goals from a business process for supporting adaptive workflows. The approach consists of a static analysis of the global workflow state. Goals derive from individual BPMN elements and their interactions. For validating the theory, we developed the BPMN2Goals tool, which has been used for supporting a middleware for self-adaptation.},

abstract = {With the increased number of elderly people in developed countries, assistive robotics is gaining more attention allowing to support home care assistance. Here, assistive robotics is adopted to monitor the activities of daily living (ADL) of patients with mild neurological disorders to limit the human monitoring, usually representing a burden for family members. In order to improve the effectiveness and user acceptance level of the robotic system, a middleware layer, able to automatically generate monitoring plans for home care patients, is proposed. The plans are generated as workflow of services, each one representing a monitoring task that can be executed by different devices, including humans, in different ways. We show that a service-oriented approach allows generating adaptive monitoring plans for patients with different levels of neurological disorders, taking into account the dynamic nature of their personality profiles, as well as of the environment they live in.},
