A QFD-AHP-Based Approach for Determining Storage Performance Parameters

Abstract

Storage Reliability plays an important role for long-term storage products, while degradation of storage performance parameters directly reflects the changes of storage reliability. In this paper, a storage performance parameter determination method was brought forward to select the performance parameters to be monitored during the product storage period and provide support for maintenance guarantee for state-based products and thereby improve the storage reliability level of products. The process and specific methods of storage parameters determination was presented. By analyzed from the product storage profile, storage environment, component internal characteristics, failure modes and mechanisms and other aspects, the performance parameters that may be affected by the storage for different components of product were obtained and thereby characteristic requirements matrix of storage performance parameters were established to determine the weight of characteristic requirements through AHP and evaluation, comparison and optimization of parameters were conduct, and then the product storage performance parameters were determined.
