| 摘 要： | 针对过程系统最优综合的混合整数非线性规划（ＭＩＮＬＰ）模型，提出了一个整型变量松弛的新算法－罚函数－凑整算法，只需求解ＮＬＰ问题就可得到过程系统最优综合ＭＩＮＬＰ问题的解。典型算例表明，计算时间和算法的有效性都优于传统的ＭＩＮＬＰ分解算法。

| Abstract: | The mathematical and physical model of temperature field caused by pulse laser irradiation on the surface of the specimen has been established with complex initial conditions, and the temperature distribution is obtained with finite difference method for investigating into the time and space characteristics of temperature about effects between laser and materials. This paper can be greatly helpful to analyze the heat absorbing effect and heat bending of material. |
