In the railway technical centers, scheduling the maintenance activities is a very complex task, it consists in ordering, in the time, all the maintenance operations on the workstations, while respecting the number of resources, precedence constraints, and the workstations' availabilities. Currently, this process is not completely automatic. For improving this situation, this paper presents a mathematical model for the maintenance activities scheduling in the case of railway remanufacturing systems. The studied problem is modeled as a flexible job-shop, with the possibility for a job to be executed several times on a stage. MILP formulation is implemented with the Makespan as an objective, representing the time for remanufacturing the train. The aim is to create a generic model for optimizing the planning of the maintenance activities and improving the performance of the railway technical centers. At last, numerical results are presented, discussing the impact of the instances size on the computing time to solve the described problem.

“…Accordingly, the cost-benefit analysis methods were investigated by researchers to find the best solutions to realize the risk reduction in a cost-effective way (Ikpe et al, 2012;Seiler et al, 2016). More importantly, as studied by Karakhan et al (2018), Panwar and Jha (2021), and Bakhtiary et al (2022, not only many factors were involved in the safety performance improvement, but also a complex and interrelated connection existed between the safety, quality, cost, schedule, and other construction activities. That is, finding the best trade-off solutions for the project Chapter 2 -Literature review improvement, including the safety issues, should be indispensable, i.e., it is necessary to incorporate the MOO solving methods.…”

I have to say deepest gratitude only goes to my supervisor Prof. Zhang Limao for his sincere guidance and kind support throughout the research. After the completion of my undergraduate study, I had worked for several years, and I lost. I lost my motivation and didn't know what should I do next. I had tried part-time jobs for years, and out of those experiences, I thought being a teacher may be the right thing for me. I believed I was good at learning and I loved sharing my knowledge and communicating with others.That's why I decided to get back to school, pursuing a doctoral degree so that I could be a teacher one day. To be honest, however, I was not that confident. It took courage for me to make this decision, and I would try my best without doubt, but I also acknowledge that I had left school for too many years, and I wasn't very sure if I could catch up and become a qualified doctoral candidate in time. So, firstly, I have to thank prof. Zhang for giving me the opportunity to be a doctoral student here. Secondly, it was his demanding and supportive supervision that really changed me. I had to admit that I was kind of stressed at the beginning, for that I was way behind from the schedule. I had too much to learn, and it was my own responsibility to catch up in time. However, prof. Zhang tutored me with unbelievable patience. I cannot even remember how many times and how much time prof. Zhang had spent to teaching me even if I made the stupidest mistakes. I just know that I may achieve nothing if without his great patience and valuable, inspiring, and professional tutorial. What's more, he sets an example of being a good supervisor for me. He not only helps me become a qualified doctoral student, but also his professionalism, dedication, and meticulous attitude enlighten me of what a great supervisor is and make me determined to be one as he does. Now, I know how, I am confident and I am resolved that I will become a qualified professor.Surely, I am also deeply grateful to my family, my parents and my beloved sister.You are always there to support. Thank you.
