Systems engineering, basically an applications of systems analysis to the design and also procurement that hardware equipment to accomplish specific ends, have the right to be an reliable tool of monitoring when fine defined and consistently implemented. The essential commodities of the equipment engineering procedure and your programmatic use are described in this section.

You are watching: As part of the overall systems engineering process

The systems engineering procedure involves the top-down advance of a system"s functional and physical needs from a basic set of mission objectives. The purpose is to organize information and also knowledge to help those that manage, direct, and also control the planning, development, and operation the the systems vital to attain the mission (Sage, 1992). The system"s physical requirements lead to the details hardware contents that should be gained or arisen to perform the determined functions. The solution engineering procedure should be conducted in a means that includes factor to consider of alternative system configurations. The an outcome should be a set of traceable demands that may be supplied in design and also procurement and also in system verification and also validation, a baseline description of the physical system, and also a baseline description of the operational concept. This should also include a collection of documented interfaces to ensure compatibility of different parts that the mechanism as they space developed. The procedure being supplied in the Tank rubbish Remediation system (TWRS) routine at Hanford follows from what is defined above; that is illustrated in figure 1.

Several terms offered in systems engineering are defined listed below for the convenience that the reader. Traceability imposes the problems that the interdependencies amongst physical and also functional demands be made explicit and also that each requirement be trackable longitudinally with the whole systems engineering process and through the system" s full life bicycle (Eisner, 1997). System verification is a two-step procedure to assure, first, that system design successfully captures the full set of device requirements, and second, the the mechanism hardware and software completely implement the design. System validation is the process of assuring that, as soon as the system is developed, that operational ide will fulfill the original system requirements (Sage, 1992).

Baseline descriptions, both of style of the physical system and of the features the device is an alleged to perform, as soon as built, are essential to the process of editing the device as new information or endure is obtained. Configuration monitoring and adjust control are important quality assurance actions that ensure alters to the baseline occur in a planned manner and also are thoroughly documented, so that implications for device performance room understood. The direction that desirable alters is stated through configuration control (Sage, 1992). The system"s initial baseline description is additionally referred to together its conceptual architecture.

The systems engineering procedure provides worth to the development, management, and implementation that a large program by ensuring:

orderly definition of a device through top-down advance of functions and requirements; clear distinction between architecture requirements developed by the program/project (potentially modifiable) and also externally enforced constraints (not conveniently subject to modification); top-down consideration and also evaluation of alternative solutions and designs, and also completeness and traceability for style of device elements and also interfaces, for construction and adjust control, and also for the system verification and also validation plan(s).

This value of the equipment engineering procedure may be realized in a variety of ways, including:

increased ability to estimate device life-cycle costs, reduced redesign early out to factor to consider of the entire system throughout its development, increased ability to effect style changes and retrofits because of clear traceability of requirements, design features, and also configuration control, and also increased probability of achieving the best technical de-
