Design for quality and reliability using expert system and computer spreadsheet

For all the products, quality and reliability should be designed in. EASYDFQR, which is a computer package for design for quality and reliability, has been developed. Design engineers can use EASYDFQR to obtain important design guidelines for quality and reliability. EASYDFQR is a PC-based expert system. Its knowledge base contains expertise about quality and reliability, such as reliability models, design approaches, failure modes, effects, and criticality analysis (FMECA), fault tree analysis (FTA), derating technique, Kaizen, etc. It can integrate with computer spreadsheets making possible tabular design calculations of quality and reliability. It supports computer graphics for the explanation of design guidelines. In addition, design engineers can obtain the knowledge they need via the shortest path using EASYDFQR. In simple words, EASYDFQR is very helpful for product design.
