提出了应用基于非线性目标规划方法的多目标优化技术来执行一般平面机构的优化综合。在这种优化技术中，首先确定设计问题的目标，并根据其相对重要性排列优先级。然后进行机制分析，以确定设计变量及其与因变量的关系。采用非线性目标规划技术来确定最能满足问题所需目标的设计变量的最佳值。这种优化技术的独特之处在于它能够将所有目标直接纳入优化过程。因此，该方法无需为了优化的目的而识别目标或将目标组合成单个目标。使用非线性目标规划技术研究了多个具有多个目标的说明性机制综合问题以获得最佳解决方案，并且该方法在所有情况下都产生了准确且可接受的解决方案。介绍了该方法在三个典型工业型机理综合问题中的应用，并对结果进行了讨论。
The application of multiple objective optimization techniques based on the methods of nonlinear goal programming to perform optimal synthesis of general planar mechanisms is presented. In this optimization technique, the objectives of the design problem are first identified and prioritized according to their relative importance. The mechanism analysis is then performed to identify the design variables and their relationships to the dependent variables. The nonlinear goal programming technique is employed to determine the optimal values for the design variables that best satisfy the desired objectives of the problem. The uniqueness of this optimization technique lies in its ability to include all the objectives directly in the optimization process. This method, thus, eliminates the need to identify or combine the objectives into a single objective for the purpose of optimization.Several illustrative mechanism synthesis problems with multiple objectives were studied for optimal solutions using the nonlinear goal programming technique and the method produced accurate and acceptable solutions in all cases. The application of this method to three typical industrial type mechanism synthesis problems is presented and the results are discussed.
