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.
When the objective function f is a vector rather than a scalar, the problem becomes a multi-objective optimization one. If the design optimization problem has more than one mathematical solutions the methods of global optimization are used to identified the global optimum. Optimization Checklist [2] Problem Identification; Initial Problem Statement
Value-based engineering (VBE) is a system development and innovation approach that implements the IEEE St. 7000 "Model Process for Addressing Ethical Concerns during System Design" released in 2021. [1]
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.
A problem statement is a description of an issue to be addressed, or a condition to be improved upon. It identifies the gap between the current problem and goal. The first condition of solving a problem is understanding the problem, which can be done by way of a problem statement. [1]
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.
Abercrombie & Fitch's chairman and chief executive Michael Jeffries, in this Feb. 16, 1998, file photo, has a contract that includes a $1 million annual salary & a retirement package not tied to ...
The problem P1 can be solved directly by computing antiderivatives. However, this method of solving the boundary value problem (BVP) works only when there is one spatial dimension. It does not generalize to higher-dimensional problems or problems like + ″ =. For this reason, we will develop the finite element method for P1 and outline its ...
