In computer science, rate-monotonic scheduling (RMS) [1] is a priority assignment algorithm used in real-time operating systems (RTOS) with a static-priority scheduling class. [2] The static priorities are assigned according to the cycle duration of the job, so a shorter cycle duration results in a higher job priority.
Deadline monotonic priority assignment is not optimal for fixed priority non-pre-emptive scheduling. A fixed priority assignment policy P is referred to as optimal if no task set exists which is schedulable using a different priority assignment policy which is not also schedulable using priority assignment policy P. Or in other words: Deadline ...
In some applications and programming languages, notably Microsoft Excel, PlanMaker (and other spreadsheet applications) and the programming language bc, unary operations have a higher priority than binary operations, that is, the unary minus has higher precedence than exponentiation, so in those languages −3 2 will be interpreted as (−3) 2 ...
Dynamic priority scheduling is a type of scheduling algorithm in which the priorities are calculated during the execution of the system. The goal of dynamic priority scheduling is to adapt to dynamically changing progress and to form an optimal configuration in a self-sustained manner.
In computer science, priority inversion is a scenario in scheduling in which a high-priority task is indirectly superseded by a lower-priority task, effectively inverting the assigned priorities of the tasks. This violates the priority model that high-priority tasks can only be prevented from running by higher-priority tasks.

U.S. President-elect Donald Trump refused on Tuesday to rule out using military or economic action to pursue acquisition of the Panama Canal and Greenland, part of a broader expansionist agenda he ...
For example, a value of 3 for (Req1, Req2) indicates that requirement 1 is valued three times as high as requirement 2. Trivially, this indicates that (Req2, Req1) has value ⅓. In the approach of Karlsson and Ryan, five steps for reviewing candidate requirements and determining a priority among them are identified. These are summed up below. [3]
