Pre study: RAMS/LCC in the planning phase

Published: 13 June 2016

The purpose is to develop applications and methods for using RAMS and LCC in the design phase. The aim is to increase functional, operational and delivery reliability and maintenance of railway facilities by changing the behavior of the projector to rely on regulations instead of using the same or better results (with the help of RAMS / LCC) (as well as creating climate for innovation while taking into account the best cost-effectiveness Throughout the plant's entire life cycle.

Life Cycle Cost Analysis (LCC) is used to get an overall picture of the cost effects such as rebuilding of the track results in the entire life of the track. In addition, the LCC analysis is attached to the decision-making basis when it comes to weighing between two or more design or technology alternatives. The analysis estimates costs for investment, maintenance and operation for the current options.

The advantages of LCC are that the method provides a comprehensive picture of the costs that an alternative choice entails. The decision base thus becomes better when it comes to choosing alternative solutions and is not limited as usual to the investment component only.

The method is used in the real estate sector to assess the effects on operating and maintenance costs of alternative technical solutions for refurbishments and additions.

RAMS is used to describe a product / facility operating, functional, maintenance, and safety.

The advantages of RAMS are that the methodology can be used in the development / projection phase and the maintenance contract period to identify / predict the likelihood of errors / events and to find methods / strategies for preventing / safe functioning, reliability, maintenance and safety in the product's operating phase.
