内容简介

The development of complex engineering products faces many challenges such as meeting the development budget, release time, and performance goals. Most of the new product development processes have been experiencing challenges to meet these goals within an increasingly competitive global market environment. In addition, the reliability of the new product has always been a major concern for new product developers and it has been a difficulty to balance the development cost and time while increasing product reliability

The main goal of this research is to develop methodologies to support new product developers meet their product requirements and strategic business goals. This research consists of two main parts. In the first part, a novel methodology in modeling and optimizing the reliability growth is proposed, which considers the multiple stages of a new product development process and provides an optimal reliability growth plan in terms of time, cost, and the reliability of the newly developed products. The proposed approach differs from the existing research in the literature by, (1) considering multiple stages of the reliability growth program in the early stages of the new product development process, and (2) optimizing all three new product development goals simultaneously. The second part of this research provides an innovative approach to model and optimize the planning of a verification and validation (V&V) process in the early stages when designing a new product. This mathematical approach provides an optimal way of implementing a design verification and validation process to have maximum reliability improvement of a new product under development, when the implementation time and cost are limited.

复杂工程产品的开发面临着满足开发预算、发布时间和性能目标等诸多挑战。在竞争日益激烈的全球市场中,大多数新产品的开发过程都面临着实现这些目标的挑战。此外,新产品的可靠性一直是开发人员关注的主要问题,在提高产品可靠性的同时,如何平衡开发成本和时间一直是一个难点。

李钊军博士研究的主要目标是提出方法来支持新产品开发人员满足其产品要求和战略业务目标。研究主要由两个部分组成,第一部分提出了一种新的可靠性增长建模与优化方法,该方法考虑了新产品开发过程的多个阶段,并从时间、成本和新产品的可靠性方面提供了最优的可靠性增长方案。本文提出的方法与现有研究的不同之处在于:(1)在新产品开发过程的早期阶段考虑可靠性增长计划的多个阶段,(2)同时优化三个新产品的开发目标。本研究的第二部分提供了一种创新性方法,对设计新产品早期阶段的验证和确认过程进行建模与优化。在时间和成本有限的情况下,提供了一种实现验证和确认过程的最佳方法,最大限度地提高正在开发的新产品的可靠性。
