ISBN: 9798191741321 - handbook of systems engineering principles and practice: from requirements and architecture to integration, verification, and lifecycle delivery (5 Ergebnisse)

Paperback. Zustand: new. Paperback. Complex systems rarely fail because a calculation was wrong. They fail because two teams held incompatible assumptions about an interface and neither wrote them down. They fail because a requirement was satisfied exactly as written, and the written version was not what anyone needed. They fail because a decision made in the first eight weeks, on very little information, quietly determined an outcome that surfaced three years later. These are failures of relationships, and no single engineering discipline owns them. Most engineers arrive at systems responsibility sideways. They were excellent subsystem engineers, they were handed ownership of the whole, and they found that the skills which earned them the promotion do not automatically extend upward. The available guidance often makes this harder: methods are presented as procedures without the conditions under which they break, and worked examples skip the arithmetic that would have taught something. This handbook was written to close that gap. Seventeen chapters across seven parts, with worked examples that show every step, practice problems with answer keys, three appendices, a glossary and a list of symbols.Methods are presented with their documented failure modes - why a trade study built on multiplied ordinal scores can reverse its ranking when a scale is relabelled, and why a risk matrix built the same way can rate a low-probability catastrophe below a routine annoyance.Worked examples carry their units through every calculation, state assumptions before using them, and show intermediate quantities instead of jumping to a result.Allocate reliability across subsystems, build fault trees and minimal cut sets, and see where redundancy stops helping because of common-cause failure.Construct a verification cross-reference matrix, select verification methods deliberately, size test margin against measurement uncertainty, and judge what must be re-verified after a change.Write requirements that are verifiable, separate derived from allocated, and review a set for ambiguity and completeness.The vocabulary is locked and used consistently, because verification and validation are not interchangeable, a need is not a requirement, and architecture is not design - and each collapse corresponds to a real failure mode.Proportionality is addressed directly: how much process a programme actually warrants, with the honest acknowledgement that this judgement is made badly in both directions.Coverage follows the shape of the work: emergence, boundaries and system context; lifecycle models, stage gates and technical reviews; stakeholder elicitation, operational concepts and measures of effectiveness; requirement quality, traceability, budgets and margin; functional decomposition, states and modes; architecture views, modularity and design structure matrices; interface specification and the two-party ownership problem; model-based practice; trade studies, value functions and sensitivity; model fidelity and uncertainty propagation; the human element; reliability, availability, maintainability and safety; risk, opportunity and management reserve; integration, verification and validation; configuration and data management; technical planning and leading indicators; and transition, support, obsolescence and retirement. It is written for the practicing engineer who has become responsible for a system rather than a component, for graduate students meeting these methods formally in a one- or two-semester sequence, and for the experienced practitioner who needs one specific method on one specific afternoon. It assumes an engineering background - algebra, basic probability, elementary calculus - and no prior systems engineering training.
