Decomposition of tasks and selection of optimal schemes are key procedures in high-end equipment development processes. However, such procedures are highly innovative, technology intensive, interdisciplinary, and multi-party engineering projects, making the decomposition and scheme selection more difficult and complicated than that in the development of ordinary equipment. In this study, we consider three factors, namely, functional structure, task granularity, and task feasibility in task decomposition of high-end equipment development. Based on the principles of systems engineering, a method of task decomposition is proposed. As for decomposition scheme selection, a method based on the superiority and inferiority ranking (SIR) method mixed information and multiple attribute decision making is proposed by considering attributes of scheme feasibility, uncertainty risk and task integration complexity. To verify the proposed method, development of a military electric vehicle is used as an example to demonstrate the calculation process.

高端装备开发任务分解与方案选择方法

任务分解和最佳方案的选择是高端设备开发过程中的关键过程。然而，这些程序是高度创新的，技术密集的，跨学科的和多方的工程项目，使得分解和方案选择比普通设备的开发更加困难和复杂。在这项研究中，我们考虑了三个因素，即高端设备开发任务分解中的功能结构，任务粒度和任务可行性。基于系统工程原理，提出了一种任务分解方法。至于分解方案的选择，结合方案可行性，不确定性风险和任务整合的复杂性，提出了一种基于优劣排序（SIR）混合信息和多属性决策的方法。为了验证所提出的方法，以军用电动汽车的开发为例来演示计算过程。
