线-单元（或线-seru）转换是装配系统的一种创新，但很少受到关注。其实质是拆除装配输送线，采用一个小型装配单元，称为seru（或单元）。在本文中，我们讨论了如何做这样的线细胞转换，特别是集中在组装细胞形成（ACF）和组装细胞加载（ACL）。我们进行了64个阵列的全析因实验分析，其中包括三个因素：工作站，产品类型和产品批量。我们构建了一个双目标线细胞转换模型，最小化总吞吐量时间（TTPT）和总劳动时间（TLH）。三个非支配的解决方案，从两个目标模型被用来评估性能的线细胞转换。通过研究ACF和ACL的实验结果，我们总结了几个管理的见解，可以用来帮助成功的线细胞转换。
The line–cell (or line–seru) conversion is an innovation of assembly systems that has received less attention. Its essence is dismantling an assembly conveyor line and adopting a mini-assembly unit, called seru (or cell). In this paper, we discuss how to do such line–cell conversions, especially focusing on assembly cell formation (ACF) and assembly cell loading (ACL). We perform 64 arrays of full factorial experiment analysis that incorporate three factors: work stations, product types, and product lot sizes. We construct a two-objective line–cell conversion model that minimises the total throughput time (TTPT) and the total labour hours (TLH). Three non-dominated solutions obtained from the two-objective model are used to evaluate the performance of the line–cell conversion. By investigating the experimental results of the ACF and the ACL, we summarise several managerial insights that could be used to help successful line–cell conversions.
