中文摘要 | 排序問題為生產管制活動之主要課題,傳統方式乃假設工作時間為確定數之前提下來作其排序工作。但揆諸事實,往往工作時間為模糊數,本文乃在工作時間為模糊數之前提下,對二製程,Johnson法則之開始時間;完成時間及相關性質作推導及分析,最後以一釋例解說。 |
英文摘要 | Scheduling is a major topic in production control activities. Traditionally, work time has been assumed to be a crisp number in scheduling. But, Practically, work time is a fuzzy number. This paper is aimed at studying the flow-type scheduling of two-process Johnson's Rule on the basis of the fact that work time is a fuzzy number. Fuzzy numbers and LR-type fuzzy numbers are introduced to derive fuzzy start time, fuzzy finish time and their related properties. Finally, an example is given to explain the above. |
