...adds new methods to your RAMS toolbox and new skills in the application of these.

Brief background of course

This course is the specialization course in reliability, availability, maintenance and safety (RAMS) in the last fall semester of the (2 year) international master program in RAMS program and the (5 year) master program in Mechanical Engineering (in Norwegian: Produktdesign og Produksjon - PUP).

...

The course belongs to the large envelope of RAMS , for example for the optimization of system design, operation, and maintenance. The course is part of the big envelope of courses given from the department of Production and Quality Engineering at NTNU, and it is lectured with personnel that belong to the .  The course is adminstred by the RAMS group at this department. It is expected that the students already have taken (or have relevant background corresponding to):

...

This course replaces the earlier arrangement with two specialization modules in RAMS, one in risk and reliability and one in maintenance optimization (each with 3.75 credit points). The new (merged) course TPK 5170 therefore includes both subject This means that TPK 5170 includes some subjects from both areas: risik and reliability and maintenance optimization, and gives 7.5 credits (i.e., as a regular course normally does at NTNU).

• You may ask why this is necessary, if the you (for example) are focusing mainly on risk analysis in the specialization project and master thesis. The answer is rather simple: This course should give you the remaining topics that we - as a RAMS group - think you should have when you leave NTNU with a specialization in RAMS.

...

The course responsible person in for TPK 5170 in the fall of 2014 is Professor Mary Ann Lundteigen. I will also give about  She will give approximately 50% of the lectures. This Since this is a specialization course, need the support of some  some "specialists" on certain topics. Some special topics will thererfore be lectured by Associate Professor Yiliu Liu and our new (at NTNU) Professor Anne Barros. As the course responsible, I will always be present in the lectures (with one or two exceptions) , also those not given by meare brought in for specific topics. For example, Associate Professor Yiliu Liu  will lecture methods like PetriNets. Lectures that belong to the topic maintenance optimization are planned to be lectures by our new Professor Anne Barros.

Course objective and motivation

Expected learning outcome

More specifically, the learning outcome should be: 

Knowledge:
Basic insight into the Obtain a more thorough understanding of the theoretical foundation and the practical applications of RAMS assessment and optimization methods. 

Skills:
Being able to identify and use framework and methods available to solve suitable frameworks, methods, and software and to use these to solve RAMS assessment and optimization tasks, and to select suitable methods for also more complicated situations. Solve optimization problems in practice. Assess RAMS performance for systems. 

General competence:
Understand RAMS as an important cornerstone of industrial and commercial systems and in the public administration. 

Industry relevance

Reliability assessments of safety-critical systems are key services provided by many consultancy companies, such as with Safetec, Lloyd's Register Consulting, and DNV-GL (link to the GL-part of the services), and Lilleaker Consulting. Manufacturers like ABB, Siemens, AkerSolutions, FMC, Kongsberg Maritime and many others need to design systems in light of reliability requirements, and also demonstrate (sometimes with assistance of the consultancy companies) that the reliability requirements are met. End users, like railway service providers like Jernbaneverket, oil companies like Statoil, Det Norske, GDF-Suez, Shell and Conoco-Phillips, and Wintershall and other industries like smelting plants and water power suppliers must be competent to select proper system design, follow up the system performance and select the most suitable maintenance strategies to keep costs and safety within the accpetable limits.

Topics covered

Topics to be covered are as part of the course are (organized according to whether the application is mainly for safety-critical systems or production-critical systms, or both) presented below. Note that more than one lecture may be used to cover one particular topic. See the lecture plan for more details. 

Reliability analyses of safety-critical systems

...

• Development of reliability requirements
  
  "Safety integrity level (SIL) is a key reliability performance measure used for safety-critical systems. Reliability requirements are therefore often given as SIL requirements are identified in an extension of the risk analysis, using methods often refered to as SIL allocation, SIL targeting and SIL classification. Key methods like Layers of protection analysis (LOPA), risk graph, and minimum SIL are presented and discussed."
  
• Reliability analyses: Extending with new analytical & dynamic modeling approaches.
  
  "In TPK 4120, some analytical formulas were introduced to calculate the average probability of failure on demand (PFD). It was also shown how the average PFD may be calculated using Markov methods and fault tree analysis. This reliability measure is of high importance in relation to SIL, as a relationship is established between a SIL requirement and the maximum PFD tolerated for a safety function. In this course, we go a step further and introduce the foundations for analytical formulas presented in IEC 61508 (a key standard for reliability of safety-critical systems), the PDS method (a method along with a set of analytical formulas widely adapted in the Norwegian oil and gas industry, but which has a wider application area), and dynamic modeling, using Petri Nets."
  
  
• Special analysis challenges (possible candidates for under this heading):
• Partial and imperfect testing
• Follow-up of SIL requirements in the operational phase
• Hardware fault tolerance - Hardware design constraints of safety-critical functions
