System design and implementation decisions for ParaMoise organisational model

ParaMoise is a novel organisational model that permits to specify parallel and concurrent systems' organisation and reorganisation. Workflows, locks and multiple organisation managers are the entities that differentiate this model from it antecedent, the Moise+ framework. All these entities must be efficiently designed and implemented to ensure the practical usage of the theoretically formulated model. The main challenge here is the distributed synchronisation of workflows and locks, that will maximise the performance of the system. This paper presents and analyses different workflows and locks management approaches that can be used to achieve this goal: from basic centralised or middleware based solutions, towards truly decentralised coordination mechanisms.
