System Mode Changes - General and Criticality-Based
نویسنده
چکیده
In this paper we summarise, and attempt to unify, the many descriptions that have been published on general mode changes. We then use this summary to position the criticality mode change. We conclude that a criticality mode change (from low to high) is closest in nature to a (graceful) degradation mode change following (partial) system failure. However, a criticality mode change (from high to low) has more in common with a (exceptional) functional mode change. The paper also addresses systems that may have both criticality and general mode changes.

State-Based Mode Switching with Applications to Mixed-Criticality Systems
We present a new graph-based real-time task model that can specify complex job arrival patterns and global statebased mode switching. The mode switching is of a mixedcriticality style, enabling immediate changes to the parameters of active jobs upon mode switches. The resulting task model therefore generalizes previously proposed task graph models as well as mixed-criticality (sporadic) task mo...
متن کاملSchedulability Analysis of General Task Model and Demand Aware Scheduling in Mixed-Criticality Systems
Nowadays, the embedded systems are undergoing an unprecedented trend towards integrating components or tasks of different criticality levels onto a common computing platform, as the task integration can reduce the “SWaP” (Size, Weight, and Power) related costs. Those systems, commonly referred to mixed-criticality systems, consist of functionalities with two or more distinct criticality levels,...

In System Engineering, one of the most critical process is the requirement management, particularly when it deals with the safety requirements. These one are non-functional requirements and are related to emergent properties, which come from the integration of the different system components. They must be identified as soon as possible, because they are guards to validate or not the system, whi...
متن کاملDeveloping an economical model for reliability allocation of an electro-optical system by considering reliability improvement difficulty, criticality, and subsystems dependency
The nature of electro-optical equipment in various industries and the pursuit of the goal of reducing costs demand high reliability on the part of electro-optical systems. In this respect, reliability improvement could be addressed through a reliability allocation problem. Subsystem reliability must be increased such that the requirements as well as defined requisite functions are ensured in ac...
متن کاملFuzzy FMECA-Based Reliability Analysis of Welding Robots
A welding robot is an advanced piece of machinery in industry, especially in the field of industrial automation. As a complex system, it has a high failure probability because it manipulates, controls and performs complicated objects and tasks. Therefore, more attention has recently focused on the reliability of a welding robot. Reliability is very important because its performance will affect ...
