The paper presents strategies to find the optimal production in a company, policies for preventive
maintenance, and benefits of maintenance. Quite often companies disregard the importance of
preventive maintenance. I always compare it to a vehicle, our personal car or vehicle. Some usually
disregard any preventive maintenance schedule resulting to breakdown of the vehicle or worse,
overhaul is needed. In companies, maintenance serves as the set of activities executed to keep the
system into a state where it can perform its function. Some of the maintenance activities or procedures
can be executed during the production and some can be executed during regular production stops
(holidays, weekends, evenings). However, in some scenarios, shut down is needed to perform
maintenance. This sometimes causes tension between the maintenance and production departments of
an organization. On the other hand, production department needs the maintenance schedule for long-
term benefits for their equipment and machines, but at the same time it leads to shutting down and
production loss. It is clear in the paper that both can benefit from maintenance activities.
It was good to have the case study of Mitsubishi Electric about Stadverke Rotenburg Municipal Services
in Germany as an example for the paper as it showed how service levels were managed and how repair
time and costs were reduced. It was also documented in the paper that issues were discovered early and
there was a real-time data analysis executed.
It is highly important in today’s global competitive markets the timely and cost-effective production
performed by organizations. Especially for manufacturers, it is vital to optimize utilization of equipment
and machines by ensuring schedules are efficient. Usually, the problems of scheduling include those
machines are always available. In realistic situations, machines are unavailable for many different
reasons such as unexpected maintenance and breakdowns.
Furthermore, the topics of the paper cover the benefits of production maintenance like the effective use
of resources and addition of maintenance activities to production scheduling problems. Other machine
environments must also be inspected thoroughly.
