This research proposal is concerned with the analysis and optimization of systems performance over their life-cycle: from the design stage to the recovery and reuse stage. In a context of increased competition and rationalization, performance gains can ensure competitiveness, profitability and increase customer service. Particularly, this research program focuses on modeling and optimizing the performance for systems subjected to random failures in an environment-friendly context. Systems performance is defined and evaluated as one or the combination of several of the following indicators: reliability, availability, maintainability, energy consumption, quality, etc. This performance is affected by the system's design, production and assembly processes, distribution, operating environment, integrated logistics, maintenance, etc. It is therefore required to model the system in order to identify the main factors which reduce its performance and develop decision-tools for the selection of performance improvement actions. Research actions will be dedicated to defining the performance factors and their assessment at different stages in the life-cycle. Which should, subsequently, help analyzing and modeling the system behavior. This research program consists of 6 main topics: 1-Development of performance monitoring, assessment and optimization models. 2- Reliability and availability modeling for multi-components systems subjected to random failures. 3-Provisioning strategies integrating the recent development of connective technologies. 4- Maintenance strategies combining the use of new and reconditioned replacement parts. 5- Development of decision-making models and tools for the selection of optimal recovery options for retired systems. 6- Life Cycle Engineering.

本研究计划关注系统在其生命周期内的性能分析和优化：从设计阶段到回收和重用阶段。在竞争加剧和合理化的背景下，绩效提高可以确保竞争力、盈利能力和提高客户服务。特别地，本研究项目侧重于建模和优化环境友好环境下随机故障系统的性能。系统性能被定义和评价为以下几个指标的一个或组合：可靠性、可用性、可维护性、能耗、质量等。这一性能受系统的设计、生产和装配过程、分销、运行环境、综合物流、维护等因素的影响。因此，需要对系统进行建模，以确定降低其绩效的主要因素，并开发决策工具，以选择绩效改进行动。研究行动将致力于确定生命周期不同阶段的绩效因素及其评估。这将有助于随后对系统行为进行分析和建模。本研究计划包括6个主要课题：1 .开发性能监测、评估和优化模型。随机故障下多部件系统的可靠性和可用性建模。整合连接技术最新发展的供应策略。4-结合使用新的和已修复的替换部件的维护策略。开发决策模型和工具，用于选择退役系统的最佳恢复方案。生命周期工程。
