Objectives

The aim of this subject is to provide students with an integrated overall view of concepts, techniques and strategies most common used in Maintenance Management. A decision support system for maintenance is presented in order to allow students to solve the main maintenance management problems and to help them making the best decisions.

Learning outcomes and competences

At the end of this subject is expected that students are able to use the different tools presented throughout the subject in making the best decisions to support maintenance management. In particular it is expected that students are able to choose the best quantitative reliability and optimization techniques as a decision support system as far as maintenance strategies are concerned.

Teaching methods and learning activities

The concepts and tecniques are introduced through problems and case studies. Throughout the course some software maintenance-related packages are also presented. Computers, "datashow" and white board are used for teaching support. Two invited talks will take place on “Equipment replacement” and “Total Productive Maintenance”.
