Modern mechanical products such as aeronautical astronautic systems show the features as follows complex structure, nonlinear performance, limited samples, less information and strict demand of reliability and maintainability. All these features make the reliability and maintainability analysis is a huge challenge in precise and efficiency. Introducing the system engineer methodology into the mechanical products reliability analysis is an important and practical way. The traditional system reliability analysis methods such as FTA, reliability block diagram, Markovian approach and Petri nets are on the basis of history data. These methods can t work well and even could be inadequate in system analysis because of the complexity of structure and nonlinearity of their behaviors. For example, the space satellite is a system with complex structure. Its samples are very limited because of expensive cost, and its work environment is very complicate and uncertain.

This book describes and gives examples of systems engineering methodology and safety tools, and describes the management needed to build the bridge between these two disciplines. This bridge must be properly built at the outset and maintained throughout the life cycle of the project. 

In Chapters 4 and 5, we shall see how safety management is incorporated into the systems engineering methodology through technical and project processes. 

The technical processes of the systems engineering methodology are used to... 

As specifications are generated, a rule of thumb in the systems engineering methodology is that 50 to 250 functional/performance requirements per specification are appropriate. 

It is the requirements analysis technical process of the systems engineering methodology that resolves potential conflicts and redundancies, and further decomposes requirements so that each applies only to a single system function. 

Architectural design is strongly focused on analysis of alternatives and is part of the overall systems engineering methodology that includes Requiranents Analysis (described in Section 4.3) and Decision Management (described in Section 5.4). An initial set of functions is identified to carry out the system s overall mission. 

The SEMP is the top-level plan by which the systems engineering methodology is employed to manage the project and, as such, defines how the project will be organized, structured, and conducted as well as how the total engineering process will be controlled to provide a product that satisfies stakeholder requirements. The SEMP is supported by a project Work Breakdown Structure (WBS) that defines the project task hierarchy.

The reports produced by the Navy, Congress, and Sandia as a result of this incident show a clear example of what happens when the tools of system safety are not incorporated into a systems engineering methodology. The battleships had been recommissioned without solid manning and training plans in place, and oversight of safety procedures was not exerted.
