Aerospace product development value streams design and planning for sustainable performance improvement and optimal value under uncertainty

航空航天部门对加拿大很重要，2013年为加拿大国内生产总值贡献了近280亿美元，并提供了超过17万个就业机会。该行业还将其20%的活动投资于研究和开发，使其成为该国研究和开发最密集的行业之一。随着加拿大计划在2015年进入大型喷气式飞机市场，该行业将面临日益复杂和不确定的产品开发环境。复杂的项目通常提供的效益低于预期，超出其预算范围，并且交付较晚。考虑到航空航天领域的产品开发周期和投资回收期很长，加拿大工业受益于政府的大量援助。提高航空航天产品开发价值流的绩效已成为一项迫切需要，以确保加拿大航空航天工业的持续竞争力，减少该行业对政府援助的依赖，并减少与建立一个低效率的行业相关的风险。 该研究项目的目标是在加拿大航空航天产品开发价值流的不确定性下，为实现可持续性能改进和最佳价值做出贡献。 为了实现这一目标，需要在产品开发价值流的设计、规划和控制中考虑多个战略和运营因素。 这些因素与产品开发价值流的架构、遵守法规的方法、利用率和多任务处理水平、产品开发任务规模和价值以及不确定性等有关。 航空航天产品开发价值流的性能受到缺乏综合决策工具和过程纳入这些因素的影响。 该研究计划在短期内的重点是发现，建模和量化影响产品开发价值流，流程，项目和产品的性能的因素，模型的发展相关因素水平的产品开发性能指标，将因素集成到自适应产品开发随机建模过程中，以随着时间的推移为产品的设计设定期望的因素水平，产品开发，以及考虑因素水平和不确定性的先进计划和控制优化模型的开发。 从长远来看，在设计和产品开发价值流的规划和控制中同时使用多个因素水平，将导致创建创新的，强大的和系统的优化方法，支持航空航天工业产品开发绩效的可持续提高。

The aerospace sector is important to Canada, with a contribution of close to twenty eight billion dollars to its gross domestic product, and more than one hundred and seventy thousands jobs in 2013. The industry also invests twenty percent of its activities in research and development, making it one of the most research and development intensive industries in the country. As Canada plans to enter the large jet market segment in 2015, the industry will be faced with an increasingly complex and uncertain product development context. Complex projects typically provide less benefit than anticipated, exceed their budgetary envelope, and are delivered late. Considering the very long product development cycles and payback periods found in aerospace, the Canadian industry benefits from significant governmental assistance. Enhancing the performance of the aerospace product development value streams becomes an urgent necessity, to ensure the continued competitiveness of the aerospace industry in Canada, to reduce the industry reliance on governmental assistance, and the risks associated with creating an inefficient industry. The objective of this research program is to contribute to the efforts towards the sustainable performance improvement and optimal value under uncertainty of the Canadian aerospace product development value streams. To achieve this objective requires taking into consideration multiple strategic and operational factors in the design, planning and control of the product development value streams. Such factors relate to the architecture of the product development value streams, methods of compliance to regulation; utilization and multitasking levels, product development task size and value, and uncertainty among others. The performance of aerospace product development value streams is affected by the lack of integrated decision making tools and processes incorporating such factors. The focus of this research program in the short term is on the discovery, modeling and quantification of factors influencing the performance of product development value streams, processes, projects, and products, the development of models relating factors levels to product development performance measures, the integration of factors into an adaptive product development stochastic modeling process to set desired factors levels over time for the design of the product development, and the development of advanced planning and control optimization models taking into consideration factors levels and uncertainty.  In the long term the concurrent use of multiple factors levels in both the design, and the planning and control of the product development value streams will result in creating innovative, robust and systematic optimization approaches supporting the sustainable enhancement of the aerospace industry product development performance.
