Value engineering can lead to the substitution of lower-cost materials, as with the exterior cladding that accelerated the Grenfell Tower fire in London. [1] [2]Value engineering (VE) is a systematic analysis of the functions of various components and materials to lower the cost of goods, products and services with a tolerable loss of performance or functionality.
Value-based engineering (VBE) is a system development and innovation approach that implements the IEEE St. 7000 "Model Process for Addressing Ethical Concerns during ...
In economics a trade-off is expressed in terms of the opportunity cost of a particular choice, which is the loss of the most preferred alternative given up. [2] A tradeoff, then, involves a sacrifice that must be made to obtain a certain product, service, or experience, rather than others that could be made or obtained using the same required resources.
For example, a recent Value study of the design for a new rapid transit station eliminated part of the fare collection concourse and associated structural steel framing supporting it for a savings to the project of several hundred thousand dollars.
Classic examples are meat rendering plants or a steel manufacturer. The primary problem in V-plants is "robbing," where one operation (A) immediately after a diverging point "steals" materials meant for the other operation (B). Once the material has been processed by A, it cannot come back and be run through B without significant rework.
Some examples of engineering economic problems range from value analysis to economic studies. Each of these is relevant in different situations, and most often used by engineers or project managers. For example, engineering economic analysis helps a company not only determine the difference between fixed and incremental costs of certain ...
Boundary value problems are similar to initial value problems.A boundary value problem has conditions specified at the extremes ("boundaries") of the independent variable in the equation whereas an initial value problem has all of the conditions specified at the same value of the independent variable (and that value is at the lower boundary of the domain, thus the term "initial" value).
Value-driven design is controversial because performance requirements are a central element of systems engineering. [3] However, value-driven design supporters claim that it can improve the development of large aerospace systems by reducing or eliminating cost overruns [4] which are a major problem, according to independent auditors.
