Handbook of Reliability, Availability, Maintainability and Safety in Engineering Design - Part 40 studies the combination of various methods of designing for reliability, availability, maintainability and safety, as well as the latest techniques in probability and possibility modelling, mathematical algorithmic modelling, evolutionary algorithmic modelling, symbolic logic modelling, artificial intelligence modelling, and object-oriented computer modelling, in a logically structured approach to determining the integrity of engineering design. . | Theoretical Overview of Availability and Maintainability in Engineering Design 373 i Establishing Maintenance Strategies for Engineering Design From the three fundamental principles of a maintenance strategy it is evident that all required maintenance work is made up of one or more types of maintenance that accomplish specific technical benefits. As stated previously it is the combination of these different types of maintenance that constitutes a maintenance strategy. From an engineering design perspective a maintenance strategy is the establishment of the most effective combination of the different types of maintenance to be carried out on specific equipment in order to achieve the most desired technical benefit from that equipment. This is determined through designing for reliability availability maintainability and safety . designing for engineering integrity where in this case the concept of safety is considered as part of designing for reliability . On the other hand the most effective combination of the different types of maintenance for completed engineered installations . a maintenance strategy for operational systems and equipment is established through a RAMS reliability availability maintainability and safety program DoD . 1997 . The deliverable results are the establishment of operations and maintenance procedures and work instructions in which the different types of maintenance are effectively combined into maintenance strategies for specific equipment. The established maintenance strategies for the effective care of the condition of engineering equipment are taken up in a RAMS program. The RAMS program The goal of the RAMS program is to establish policies and strategies for effective care of the condition of engineering systems and equipment through the implementation of various RAMS methods and techniques. The objectives of the RAMS program are to Ensure effective care of equipment condition. Optimise the technical benefits derived
