Abstract:
This study aimed to study the factors affecting the success of multi-product maintenance with everyone involved in the automotive industry in Rayong Province. A questionnaire was used as a tool to collect data from a sample of 166 people. The data analysis used percentage, mean, standard deviation, comparison of mean differences, one-way analysis of variance, and pairwise analysis of mean differences. The research findings revealed that:1 The majority of respondents were male, aged 31-45 years, holding executive positions, with a bachelors degree and an average income exceeding 50,000 baht. Most worked in the maintenance engineering department, had over five years of work experience, were employed in medium -sized businesses, and belonged to organizations that had been operating for more than 10 years.2 Respondents rated the overall importance of multi-product maintenance at a high level. When analyzed by specific aspects, self-maintenance, planned maintenance, specific improvements, initial tool management, quality management, education and training, safety, health and environmental management, and Total Productive Maintenance (TPM) in the office were all considered highly important. 3. Hypothesis testing results indicated that different personal factors influenced the success of multi-product maintenance. Variations in age, job position, and work experience had a significant impact. Notably, respondents aged 55 and above perceived maintenance success factors as more critical than those aged 31-45. Additionally, executives exhibited different perspectives compared to other job levels.
