Abstract
Effective resource scheduling and machine maintenance are two important interactive factors to improve prefabricated component productions. However, previous studies focused on machine maintenance without simultaneously considering stochastic resource scheduling, or studied job scheduling but neglected the resource constraint and machine availability. This paper explores the interaction between resource scheduling and machine maintenance to optimize the maintenance decisions and human resources in the prefabricated component production process. To solve this problem, a new integrated optimization model with aim of minimizing the uncertain project duration under the cost constraint is formulated. A differential evolution algorithm is designed by incorporating the simulation method. A real-life example of prefabricated walls is used to demonstrate the significance of jointly optimizing stochastic resource scheduling and machine maintenance, and analyzes the effectiveness of related parameters on the production system. Related results provide a new perspective to simultaneously consider multiple factors in the production process for future research.
