The nurse scheduling problem (NSP), also called the nurse rostering problem (NRP), is the operations research problem of finding an optimal way to assign nurses to shifts, typically with a set of hard constraints which all valid solutions must follow, and a set of soft constraints which define the relative quality of valid solutions.

The time lag between two jobs is the amount of time that must be waited after the first job is complete before the second job to begin. Formally, if job i precedes job j, then C i + ℓ i j ≤ S j {\displaystyle C_{i}+\ell _{ij}\leq S_{j}} must be true.
The interpretation of in accelerated failure time models is straightforward: = means that everything in the relevant life history of an individual happens twice as fast. For example, if the model concerns the development of a tumor, it means that all of the pre-stages progress twice as fast as for the unexposed individual, implying that the ...
Nursing Times has regularly run campaigns on issues affecting nurses including most recently Time Out for Training (2008), A Seat on the Board (2010–2011), Speak Out Safely (2013–2014) and Covid-19: Are You OK (2020–). In 2018, Nursing Times was inducted into the International Academy of Nursing Editors’ Nursing Journal Hall of Fame. It ...
Also called skilled nursing facilities or convalescent homes, nursing homes are designed for seniors who need 24-hour medical care or a high level of support with activities of daily living (ADLs ...
Accelerated life testing is the process of testing a product by subjecting it to conditions (stress, strain, temperatures, voltage, vibration rate, pressure etc.) in excess of its normal service parameters in an effort to uncover faults and potential modes of failure in a short amount of time.
Liveness analysis is a "backwards may" analysis. The analysis is done in a backwards order, and the dataflow confluence operator is set union.In other words, if applying liveness analysis to a function with a particular number of logical branches within it, the analysis is performed starting from the end of the function working towards the beginning (hence "backwards"), and a variable is ...
Diagram showing the relation between schedule padding and expected delay. Schedule padding—sometimes called simply padding, [1] or recovery time—is some amount of 'additional' time added to part or all of a schedule, in excess of the expected duration, that allows it to be resilient to anticipated delays and increase the chance that the published schedule will be met.
