介绍了自行设计并运行于ＶＡＸ机上的彩电电路优化设计系统（ＥＣＣＯＳ），详细论述了该系统所采用的电路中心值优化设计算法（按彩电性能指标优化），电路优化设计算法（按彩电电路性能理论曲线优化），以及整个系统设计功能．最后给出了两个采用该系统进行设计的电路实例．提出的优化算法，满足了工程设计要求，避免了在成品率求解中对变量维数和可接受域凸性的要求，因此有较强的实用性．
In this paper, the design and operation of the color TV circuit optimization design system (ECCOS), which is designed and run on the VAX machine, is introduced. The circuit center value optimization design algorithm (optimized by color TV performance index), circuit optimization design algorithm Theoretical curve optimization), as well as the entire system design features. Finally, two examples of circuits designed with this system are given. The proposed optimization algorithm meets the requirements of engineering design and avoids the requirement of the variable dimension and the acceptance of domain convexity in solving the yield, so it has strong practicability.
