[A] The probability that a system will be functioning at a certain point in time. Reliability parameter for repairable
systems. The stationary availability is defined using the following formula: A = 1/[1 + MDT/MTBF]. To achieve the
highest possible availability values, it is necessary to perfect all quality assurance measures regarding reliability.
However, this procedure has its technical and economical limits for given production conditions. When the au-
tomation plan is not sufficient to achieve the required reliability parameters, the principle of error tolerance, which
is based on the shortest error detection and reconfiguration times, can allow the availability value to be increased.
Compact 32-bit operating system with multitasking and multithreading that Microsoft developed especially for the
OEM market. It can be ported for various processor types and has a high degree of real-time capability. The
development environment uses proven, well-established development tools. It is an open and scalable Windows
operating system platform for many different devices. Examples of such devices are handheld PCs, digital wire-
less receivers, intelligent mobile phones, multimedia consoles, etc. In embedded systems, Windows CE is also
an excellent choice for automation technology.
