Resilience is a multi-facet property, covering four dimensions: technical, organization, social and economic. [6] Therefore, using one metric may not be representative to describe and quantify resilience. In engineering, resilience is characterized by four Rs: robustness, redundancy, resourcefulness, and rapidity.
The first type of resilience engineering work is determining how to best take advantage of the resilience that is already present in the system. Cook uses the example of setting a broken bone as this type of work: the resilience is already present in the physiology of bone, and setting the bone uses this resilience to achieving better healing ...
In structural engineering, the flexibility method, also called the method of consistent deformations, is the traditional method for computing member forces and displacements in structural systems. Its modern version formulated in terms of the members' flexibility matrices also has the name the matrix force method due to its use of member forces ...
The Connor–Davidson Resilience Scale (CD-RISC) was developed by Kathryn M. Connor and Jonathan R.T. Davidson as a means of assessing resilience. [1] The CD-RISC is based on Connor and Davidson's operational definition of resilience, which is the ability to "thrive in the face of adversity."
The tradeoff exists because accommodating flexibility requires satisfying a larger set of requirements, which results in complexity and usability compromises. [ 1 ] Design theory maintains that over their lifecycle, systems shift from supporting multiple uses inefficiently, towards efficiently supporting a single use as users' needs become more ...
Flexibility is a personality trait that describes the extent to which a person can cope with changes in circumstances and think about problems and tasks in novel, creative ways. [1] This trait comes into play when stressors or unexpected events occur, requiring that a person change their stance, outlook, or commitment.
Constant elasticity of substitution (CES) is a common specification of many production functions and utility functions in neoclassical economics. CES holds that the ability to substitute one input factor with another (for example labour with capital) to maintain the same level of production stays constant over different production levels.
Scores on the CES-DC range from 0 to 60, in which higher scores suggest a greater presence of depressive symptoms. A score of 15 or higher is interpreted to indicate a risk for depression. However, screening for depression is a complex process and scoring a 15 or higher on the CES-DC should be followed by further evaluation.
