In this thesis, we focus on the proposal of distributed workflow systems dedicated to the automation of administrative business processes. We propose an approach to build such systems by relying on the concepts of multiagent systems, Peer to Peer (P2P) architecture, Service-Oriented Architecture (SOA) and structured documents (artifacts) cooperative edition. Indeed, we develop mathematical tools that allow any workflow systems designer, to express each administrative process in the form of an attributed grammar whose symbols represent tasks to be executed, productions specify a scheduling of these tasks, and instances (the derivation trees that conform to it) represent the different execution scenarios leading to business goal states. The obtained grammatical model is then introduced into a proposed P2P system which is in charge of carrying out the completely decentralised execution of the underlying process's instances. The said system orchestrates a process's instance execution as a choreography during which, various software agents driven by human agents (actors), coordinate themselves through artifacts that they collectively edit. The exchanged artifacts represent the system's memory: they provide information on already executed tasks, on those ready to be executed and on their executors. The software agents are autonomous and identical: they execute the same unique protocol each time they receive an artifact. This protocol allows them to identify the tasks they must immediately execute, to execute them, to update the artifact and to disseminate it if necessary, for the continuation of the execution. Moreover, actors potentially have only a partial perception of processes in which they are involved. In practice, this means that certain tasks can be carried out confidentially.

使用结构化和协同编辑的移动工件进行分布式业务流程管理的语法方法

在本论文中，我们专注于致力于管理业务流程自动化的分布式工作流系统的提议。我们提出了一种通过依赖多代理系统、点对点 (P2P) 架构、面向服务的架构 (SOA) 和结构化文档（工件）协作版的概念来构建此类系统的方法。事实上，我们开发了数学工具，允许任何工作流系统设计人员以属性语法的形式表达每个管理过程，其符号表示要执行的任务，生产指定这些任务的调度，以及实例（符合它）代表导致业务目标状态的不同执行场景。然后将获得的语法模型引入到一个提议的 P2P 系统中，该系统负责执行底层流程实例的完全分散的执行。所述系统将流程的实例执行编排为编排，在此期间，由人类代理（演员）驱动的各种软件代理通过他们共同编辑的工件进行协调。交换的工件代表系统的内存：它们提供有关已执行任务、准备执行任务及其执行程序的信息。软件代理是自主且相同的：每次收到工件时，它们都会执行相同的唯一协议。该协议允许他们识别必须立即执行的任务，执行它们，更新工件并在必要时传播它，以继续执行。此外，参与者可能对他们所参与的过程只有部分了解。实际上，这意味着可以保密地执行某些任务。
