Modelling and Simulation of Operations and Maintenance (OFF640)

Modelling and Simulation is the process of designing a model of a system and conducting simulation experiments to understand the behavior of the system and/or evaluate various strategies for the operation of the system. Modeling & Simulation has become an important tool in all phases of the acquisition process and can be used within most systems life cycle processes, including requirements analysis, architectural design, design, development, test, verification, operations, and maintenance. System dynamics is a rigorous modelling method that enables us to use computer simulations of complex systems in order to design more effective policies and strategies for greater success. Asset simulation helps to determine the impact of your business decisions before they were implemented into our technical systems.

This course teaches the skills required for understanding how the structure of complex systems creates their behaviour. Learning in a world of growing dynamic complexity requires us to become systems thinkers in order to expand the boundaries of our engineering and management models. Therefore, systems dynamics modelling is important for the analysis of policy and strategy, with a focus on business and engineering applications. The course is based on system development and dynamic modelling methodology. The course teaches the most commonly used simulation techniques: system dynamics simulation (continuous systems), discrete-event simulation, and agent-based modelling with help of the most well-known simulation packages e.g. AnyLogic, Vensim, Arena.

Language of instruction



The course provides understanding and knowledge of industrial systems modelling, discrete and continuous distribution models, discrete-event simulation, system dynamics simulation, the alternatives evaluation analysis, and Performance improvement analysis. Some of the psychological and judgmental aspects of how people understand dynamic behaviours of systems, under uncertain and complex decision situations, will be discussed.

Learning outcome


  • Understand the complexity of the modern systems behaviors and multi-disciplinary systems e.g. energy systems.
  • Gain an understanding of system thinking and its toolbox.
  • Gain the required knowledge of modelling deterministic and stochastic processes, entities, events, conditions, and queues of several production and service systems.
  • Gain the required knowledge of simulation analysis: discrete events, continuous dynamics, data collection, alternatives evaluation and comparison.
  • Gain good understanding of operating production, service and energy systems.


  • Able to develop the business process model for any production and service system.
  • Able to collect the required data sets and select the effective distribution models to simulate the dynamic behavior of the studied system.
  • Able to simulate the system performance based on key metrics such as costs, throughput, cycle times, equipment utilization, energy losses and resource availability.
  • Able to evaluate potential alternatives to determine the best approach to enhancing performance.
  • Determine the impact of uncertainty and variability on system performance.
  • Run "what-if" scenarios to evaluate proposed process changes.
  • Visualize results with 2D and 3D animation.

General competence

  • Acquire system-thinking, problem-solving, multi criteria - decision-making approach.

Required prerequisite knowledge



Project report and oral presentation

Form of assessment Weight Duration Marks Aid
Project report 90/100 Letter grades
Oral presentation 10/100 Letter grades

There are no re-sit opportunities on the project assignment, if students want to take this part again, they must take the course again the next time the course is lectured.Students who do not attend the presentation cannot expect to take this part again. If there is a valid absence, the student can, by agreement with the subject teacher, complete the presentation at a later date.Students who do not pass one of the assessment sections, or wish to improve their grades, must retake all assessment sections within the same semester in order to obtain a new overall grade.

Coursework requirements

Self study/Group work, Obligatory written reports and oral presentations.
