Green system reliability assessment method based on life cycle: Resources and economical view
JOURNAL OF CLEANER PRODUCTION(2020)
摘要
The traditional assessment method of system reliability is based on unit reliability and probability theory, but the rationale behind this method of assessment does not consider resources and economy. Unit reliability tests tend to consume resources and economy, and consequently, reliability assessment of large systems tends to consume a large amount of resources and economy. Taking the series system and parallel system as examples, this study proves that the traditional assessment method of system reliability is unreasonable, especially from the perspective of resources and economy, as it does not meet green economy and sustainable development goals. The system life cycle diagram model is established on the unit life cycle. A green assessment method of system reliability is proposed from the resources and economy perspectives. This proposed method does not depend on the number of units and does not require the consumption of a large amount of resources and economy. This study promotes sustainable and cleaner production. The green assessment method of system reliability is applied to the series system and parallel system to assess system reliability. (C) 2019 Elsevier Ltd. All rights reserved.
