“…However, because maintenance activities require the machine to stop for a period of time, they should be scheduled in accordance with the production planning to avoid impeding the production system's ability to meet its production targets [6]. Study about weighted capacitated planned maintenance by considering perioddependent predetermined time limitations for the scheduled maintenance activities has been carried out by [7]. The objective of that study is to minimise fixed and variable maintenance costs with a feasible schedule.…”

In a mass customisation manufacturing system, the production schedule is tailored to the customer's specifications. However, the production system must be accompanied by an effective maintenance program to ensure that the production lines operate as intended. The purpose of this study is to optimise planned preventive maintenance across multiple production lines. An optimised Weibull distribution is proposed to model the machine's Mean Time Between Failures (MTBF), and the total expected maintenance cost is calculated using this distribution, taking into account the probability of the machines remaining operational and failing. Because the optimised Weibull distribution is a continuous distribution, in order to simulate the continuous time domain, it will be divided into several sub-systems and optimised using Bayesian optimisation during simulation. The maintenance scheduling is carried out by considering available time capacity after production scheduling was arranged. The study's findings indicate that the proposed method successfully optimised the planned maintenance schedule without interfering production activity with total cost for the proposed maintenance planning as low as IDR 50.017,75/maintenance unit time.
