生產現場是企業賺取利潤的主要場所之一，在生產過程中，迅速且正確地指派員工進入生產線進行生產，可替企業提高生產力和市場反應力並且可以降低生產成本；就製造流程而言，光組裝線具有彈性將無法適時配合多變的生產訂單，工作人力的彈性配置才能使生產線更具彈性以適應需求多變的市場。因此正確安排適當的員工進入合適的工作站進行生產在製造業將是一項重要之議題。
作業人員配置在過去生產線平衡問題之研究中，鮮少被獨立出來討論，在過去文獻中探討的僅為作業員是否擁有執行某工作站之能力，在實際情況中，由於員工的工作技能通常無法精準被評估且具模糊性，因此本研究在第四章以案例探討並利用模糊集合理論中之語意變數來表達員工技能水準，並且依照各員工之操作水準進行生產線平衡，本研究將建構一數學指派模式，以期達到較佳之工作負荷平衡，可供決策者在面對此環境下如何快速進行配置員工的決策支援模式。

In the production process, assigning the work among all workers on the production line effectively can bring higher productivity, faster responses and lower production costs. A flexible production line requires the flexible allocation of personnel to cope with various orders on schedule. Therefore, it is important to assign the right employees to the right positions in factories.
It is seldom discussed how to assign workers to workstations in the line balancing problem in the existing literature. Previous studies only considered whether workers had the abilities to do tasks or not. In fact, it is generally difficult for decision makers to evaluate the proficiency of each worker, since the evaluation process involves fuzziness. Therefore, we evaluate the proficiency of individual employee by using linguistic variables based on fuzzy set theory and thus assign workers to appropriate positions to make the assembly line more balanced. This research provides a mathematical model to enable supervisors to solve the line balancing problem and to make workloads more balanced.
