A new mathematical formulation will be investigated to model concurrent decision-making in design. Parametric models, initially developed solely to study changes in optimized quantities as problem parameters are locally perturbed, will now be examined in a broader design and manufacturing context. Motivation is provided by recent results on large parameter deformations in the field mathematical optimization. The research effort examines the theoretical properties of a new formulation, and examines the use of two different algorithms to solve the models numerically. Successful treatment of the research case studies will show how the concept of model optimality integrates the design and manufacturing decisions in concurrent engineering.

本文将研究一种新的数学公式来模拟设计中的并行决策。参数化模型最初仅用于研究问题参数局部扰动时优化量的变化，现在将在更广泛的设计和制造环境中进行研究。最近在大参数变形领域的数学优化结果提供了动力。研究工作检验了一个新公式的理论性质，并检验了使用两种不同的算法来数值求解模型。对研究案例的成功处理将展示模型最优性的概念如何集成并行工程中的设计和制造决策。
