In their day-to-day work, personnel rely on the knowledge of their colleagues to solve problems, indicating they may need assistance from others who are more competent and knowledgeable in certain areas. Drawing on a case study of the heavy equipment maintenance department, this study contributes to knowledge transfer at the individual level among non-management personnel and aims to formulate a knowledge management strategy. The study employed a framework combining Delphi, AHP and TOPSIS methods, divided into three stages. The first stage involved the Delphi method, where important factors of knowledge transfer were identified. The second stage used the Analytical Hierarchy Process (AHP) to determine the weight of these factors. In the third stage, the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) was applied to prioritize the knowledge management strategies. This study identified three major strategies for non-management personnel: training and assignment/involvement in projects, establishing a reward system and conducting after-action reviews. Among these, the personalization strategy emerged as the most preferred strategy.
