Prior studies regarding this issue have primarily focused on stable relationships between manufacturers and suppliers. The principles of Supply Chain Management emphasize that appropriate choice of a cooperative partner is the first step toward a stable relationship. Key to success is choice of a supplier capable of providing all necessary materials and services. An appropriate supplier will be able to comply with all specified customer demands and this in turn will serve to promote supply chain overall competitiveness. If otherwise, operation of the total supply chain will be dysfunctional with regard to production and product delivery both, and will ultimately result in loss of company credit. When products involved are diverse and of small quantity, other issues arise such as for example cost overruns, stock piling, throughput and delayed delivery, and so choice of a qualified supplier is even more so the most important step in Supply Chain Management. Taiwan’s aerospace industry is a typical case of the above. Quantities ordered are usually insufficient to assist in the creation of a normal buyer/supplier long-term stable relationship. Resulting consequence is that manufacturer selection of supplier is often based solely on bidding price criteria. This in turn will lead to problems directly impacting upstream supplier manufacturing management where sufficient support cannot be guaranteed. It is therefore highly necessary for aerospace industrial suppliers to create close relationships based on mutual cooperation in order to achieve the goal of mutual benefits. This present study attempts to establish a systematic supplier selection framework applicable to the Taiwan aerospace industry. Research summarizes new supplier selection criteria and includes a questionnaire, both of which are based on Dickson’s 23 indices, the indices of other researchers, and the opinions of local Taiwanese professionals. Structure of these indices is a leveled AHP Questionnaire utilized to investigate and assess suppliers. In this study a new set of criterion modified by field professionals and specifically applicable to diverse/small quantity products is proposed, these based upon the 23 indices for supplier selection (Dickson, 1966) as well as supplier selection criteria noted from other literatures. A questionnaire is created which assigns differing weights for each criterion using Analytic Hierarchy Process (AHP) principles. Finally, a supplier selection model, which combines supplier selection flow and weighed criteria, is proposed; this model is specifically applicable to products characterized by diversity and small quantity. Conclusion of this research is that many unreasonable and ineffective factors exist in current supplier selection frameworks. AHP results demonstrate the expectations of field professionals with a view to Job Lot Type Manufacturing Systems. Finally, we propose a new supplier selection framework based on our AHP analysis results for ”Job Lot Type” manufacturers. This new framework that is comprised of eight essential aspects is superior to the above noted previously utilized single criterion, bidding price.
