摘要

Ｔ公司為台灣最具規模的專業鏈條廠，藉由供應商的協助，Ｔ公司得以製造品質穩定的工業鏈條。然而隨著變化迅速的產經環境，逐漸考驗Ｔ公司與供應商的長期夥伴關係。
在標準化物料方面，對於供應商的貨源搜尋、服務、成本要求更甚從前。在模組化物料方面，對於供應商的交期、成本、品質的要求逐漸提升。在客製化物料方面，希望供應商能配合Ｔ公司的JIT、TQM之生產態勢，幫助生產成本的降低與生產效率的提升。
本文依文獻探討各種不同供應商能力及關係層次。其供應商能力包括成本能力、交貨能力、品質能力與服務能力，供應商層次包括功能層次、社會層次與結構層次。續以個案Ｔ公司進行供應商對生產管理成效影響之問題進行探究，提出下列研究結果：
1.物料特性對於採購管理中供應商能力選擇、關係程度發展之關聯：
(1)客製化之供應商選擇以供應商品質能力、交貨能力、服務能力為重點，彼此之間著重於技術開發、應用技術及物料使用成效提升之整合，因而雙方關係需較緊密程度的結構關係。
(2)模組化之供應商選擇，以供應商成本能力、交貨能力、品質能力為重點，彼此著重於交易資訊及物料應用技術整合，需要適度之社會關係層次。
(3)標準化物料供應商選擇，以供應商交貨能力、品質能力、服務能力為重點，彼此偏重於交易資訊，雙方則為交易關係。
2.供應商能力及供應商關係程度對於生產管理成效之影響：當供應商成本能力、交貨能力、品質能力及關係程度越高，對於生產成本降低的成效越高。當供應商交貨能力、品質能力、服務能力及關係程度越高，對於生產效率提升的成效越高，但各項能力需以總成本為概念，方能實現採購管理的適價、適量、適時、適質原則，獲得較高的管理成效。

T Company is the largest firm of specialized conveyor chains in Taiwan. By cooperating with its suppliers, T Company is able to produce and deliver indus-trial conveyor chains in stable quality. However, in such a rapidly varying envi-ronment, the long-term partnership between T Company and its suppliers is fac-ing a challenge.
For standardized materials, there is more requests for supplier’s resources searching, services and costs. For module materials, the requests of lead-time, cost and quality are also increasing. In customized materials, suppliers are ex-pected to cooperate into JIT, TQM in T Company’s production line so as to reach cost down and increase production efficiency.
This study focuses on the capability and relationship level between T Com-pany and its suppliers. The capability of suppliers includes cost, lead-time, qual-ity and services. As for suppliers’ relationships, it could be functional, sociality and structural relationships. As an example of T Company, this study arranges to conduct a research on the effect of suppliers on production management and proposes the research results as follows.
1.Material characteristics vs. suppliers’ capabilities selection and relation-ship development in purchasing management:
(1)The supplier selection for customized materials focuses on the sup-plier capabilities of quality, lead-time and customized services. Because it is key to integrate technical development, application skills and material usage rate, therefore there exists a closer struc-ture relationship between T Company and its suppliers.
(2)The supplier selection for module materials focuses on the supplier capability of cost, lead-time and quality. Since the trade informa-tion and the integration of material application are important, so a proper social relationship may be appropriate.
(3)The supplier selection for standardized materials focuses on the supplier capability of lead-time, quality and service. As both parties emphasize on the trade information, therefore their relationship is functional.
2.The affection of supplier capabilities and relationship level on production management: The higher capabilities of supplier cost, lead-time, quality and relationship level, the higher management effectiveness in cost down in production. When a supplier is of more capabilities in lead-time, quality, services and relationship level, there will be higher effectiveness in production rate. However, it should be necessary for each capability to base on the conception of total cost so as to carry out the principal of right price, right quantity, right time and right quality and achieve high effectiveness in management.
