The following paper proposes a framework on how to face the challenge of designing a maintenance schedule that ensures the achievement of the requirements related to the assets of a company. The presence of internal and external factors to the organization make it necessary to adjust the way of carrying out the maintenance schedule, and the ability of the company to adapt is fundamental to comply with the maintenance goal. Anticipating risky situations and taking actions to deal with them is of vital importance for the companies. However, carrying out this task is not easy, since it requires a high understanding of the system, analysis of external factors that affect performance, determination of changes in maintenance task, among others. That is why this framework is presented, where the main objective is to design of weekly maintenance schedule for a fleet of trains for the achievement of organizational requirements. To achieve this, different phases are carried out, where the principals are to increase the comprehension of the system that generates the maintenance schedule, identify the key concepts behind the way in which the schedule is designed and the creation of a model that represent the function of the system. Once the created model has been validated, a series of experiments is carried out, which seeks to define the design of more adequate maintenance schedule.
