By developing pushover methods and tendency of seismic codes to use ductile structures, the ductility concept (demand and capacity) is defined in different performance levels.
The ideal behaviour is defined in a performance index the minimisation of which defines an ideal trade-off between deviations in boiler pressure and water level from their respective setpoints and the cost of burner switches and variation of continuous input flows.
If there are m different MOEs defined in the performance attributes P i, then the single-attribute utility function of P i is written as follows: u(P_{i} ) = sumlimits_{i = 1}^{m} {(D_{i} times u(X_{i} ))^{lambda } }, (4 where D i are the MOE weights defined using the Delphi method and λ is the risk parameter.
The generation and modification of the control rules are achieved by assigning a credit or reward value (i.e., performance index) to the individual rule combinations defined in a multidimensional performance index matrix, part of which is shown in Table 1 [ 6, 50].
The peak is indeed seen often throughout the film — not in isolation, but framed by whatever built element is nearby; similarly, Rivette dramatizes, with tenderness and ferocity, his idea (one of the key themes of his half-century career) that human identity is defined in terms of performance.
Logistics quality can be "defined in terms of performance 'gaps' and is measured as the ability to distribute a product or materials in conformance with customer requirements and standards" ([29] p 350).
The design goals are defined in terms of deterministic performance functions and/or performance functions involving reliability measures.
The molecules are identified to meet the process performance defined in terms of properties.
It could have a specified process performance defined in relation to the measure requirements changing rate, given by the upper and lower limits 0 and 0.25, respectively.
IT systems have to provide to their users prescribed Quality of Service (QoS) levels, usually defined in terms of application performance, which must hold irrespectively of the significantly time-varying workload.
