The Swiss engineering master's degree

In this module, students are introduced into basic concepts of lifecycle management of infrastructures with respect to costs vs benefit. Established cost and benefit models of infrastructures are discussed. Based on lifecycle costs analysis, we introduce different methods for the assessment of maintenance strategies, and for decision making with respect to construction, preservation, and replacement. The cost-based approaches are complemented with methods for the analysis of reliability, availability, and risk.

Compétences préalables

Basic knowledge in mathemetics (introductory lecture in analysis and linear algebra)

MS Excel (implementation of formulae, graphs)

Objectifs d'apprentissage

• the students understand the function and the benefit of infrastructures, and their effect on society, economy, and environment
• the students are familiar with the challenges for sustainable development of infrastructures
• the students are familiar with concepts for deriving requirements for infrastructures, their verification and validation. 
• the students are familiar with the most important methods for decision making in infrastructure management, and are able to apply those methods in concrete cases; for example the calculation of life cycle costs or socio-economic impact, or the simultaneous minimization of costs and risks. 
• the students are familiar with the different maintenance strategies (reactive, preventive, condition-based)
• the students know different models of failure and wear behavior, and can apply them
• students know the concepts of reliability theory
• the students are familiar with the method of risk-based maintenance, and can apply this method for maintenance management
