%X 基于U型线的物流运输特性，提出一种新的位置编码及解析方式，来建构起能满足优先约束关系的工位与位置间的关系；基于该编码表示决策变量，描述出在装配生产过程存在的学习效应和加强约束；以工位最小化为目标，建立基于混合整型非线性规划的U型装配线平衡模型；把学习效应表达式离散化、将非线性模型线性化，降低了模型的计算复杂度，以快速有效求解。算例结果表明，所建模型可有效解决融合了学习效应和加强约束的第一类、混合模型U型装配线平衡问题。<br>Based on the logistic transportation characteristics of the U-shaped line, a position encoding method which identifies the relationship between the work station and location of U-shaped line is put forward and resolved. According to the position coding method, decision variables are represented, and the learning effect and sequence-dependent tasks are described. The U-shaped assembly line balancing model based on nonlinear mixed integer programming is constructed with the objective of minimizing the number of workstations. The learning effect is quantified according to positions and the nonlinear model is linearized so as to reduce the computational complexity of the model and solve the problem quickly and efficiently. The experimental examples show that the proposed model can effectively solve the type-I and mixed-model U-shaped assembly line balancing problem which is integrated with the learning effect and sequence-dependent tasks
