Decomposition method of equipment quality characteristic based on STT and fuzzy QFD

Integrative quality characteristic is an important indicator of the system project for equipment. On the basis of strategy to task technique (STT), fuzzy quality function deployment (QFD) and ADC model for evaluating weapon effectiveness, a decomposition method of equipment integrative quality characteristic was proposed. Equipment structure and mission were decomposed with this method; then, the whole system effectiveness was broken down into some key quality characteristics relating missions and lower function systems; finally a system effectiveness model formed based on these characteristics. The result makes reference to evaluate different system projects for the equipment and to choose the key quality characteristics working on the system effectiveness.
