What is a demand-based warm standby system with capacity storage?

Demand-based warm standby systems with capacity storage are modeled. Different utilization sequences of warm standby and stored capacity are considered. Multi-valued decision diagram is proposed for system reliability evaluation. Chronological characteristics of warm standby activation are embedded.

Does capacity storage with warm standby improve reliability?

However, correlating capacity storage with warm standby and assessing its profitability to reliability improvement have not been endeavored. To resolve the foregoing limitations, a novel reliability model for demand-based warm standby systems with capacity storage is developed.

What is a hot standby system?

Hot standby implies a system consisting of online components while other components function synchronously as backup [ 2 ]. The hot standby components can be put into operation immediately when system emergency occurs with more energy consumption compared with cold and warm standby.

What is warm standby?

Warm standby , as a type of redundancy technique, has been widely applied to many practical engineering systems, such as computing and power systems . The advantages of warm standby are well reported in the literature. Warm standby outperforms hot standby because it consumes less energy.

What is the difference between hot standby and cold standby?

Different from hot standby and cold standby components, warm standby components usually vary in failure rates or time-to-failure distributions before and after they become operational . Thus, the reliability analysis of warm standby systems usually differs from those of hot standby and cold standby systems.

Do warm standby and storage components compensate for capacity deficiency?

This paper focuses on the reliability assessment of capacity-based systems with warm standby and storage components, which are intended to compensate for the capacity deficiency caused by the failure of operating components.
