装配线平衡 (ALB) 将各个任务分配给工作站，同时尊重物理、安全和质量限制。双面装配线一般用于中型或大型产品（如汽车、家用电器）的生产。我们考虑了几个特征，包括分区约束、任务与任务关系、工具和站相关约束，以提供真实环境。 ALB 最常见的两个目标是最大限度地减少工人数量（类型 1）和最大限度地减少周期时间（类型 2）。本文提出了针对 1 类和 2 类 ALB 问题的整数规划公式以及解决这一复杂问题的元启发法。即使 ALB 给出的结果比我们行业合作伙伴应用的当前生产线平衡更好，也不能保证日产量会因生产线的随机性而增加。我们模拟建议的生产线平衡，为生产线平衡结果提供测试平台，并帮助识别系统中的低效率和瓶颈。
Assembly line balancing (ALB) allocates individual tasks to work stations while respecting the physical, safety, and quality constraints. Two-sided assembly lines are generally used in the production of medium or large-sized products (e.g. automotive, household appliance). We considered several characteristics including zoning constraints, the task to task relationships, tooling and station dependent constraints to offer the real-world environment. The most common two objectives for the ALB are minimizing the number of workers (type-1) and minimizing the cycle time (type-2). This article presents an integer programming formulation for both type-1 and type-2 ALB problems and metaheuristics to solve this complex problem. Even if ALB gives better results than the current line balance that our industry partner applied, it cannot be guaranteed that the amount of daily production will increase due to randomness in the line. We simulate the proposed line balances to provide a testing platform for line balancing results and to help identify inefficiencies and bottlenecks in the system.
