本研究在設計一個信任機制以提供網路致能組織(network enabled organizations) 評估與選擇潛在的供應商。期望透過此信任機制能夠有效的提高整體供應鏈的效能。
因此本研究參考文獻所提出對信任的定義與前因後果，設計一信任機制。以模具產業供應鏈為例，透過Swarm 模擬平台的幫助來評估在不同的供應商選擇策略下，整體供應鏈效能是否改變。此兩種選擇策略分別為:1.以價格及交期為決定因素,2.除了價格與交期等決定因素外，再參考本研究所提之信任機制來決定供應商。本研究設計三個實驗以分析不同的模擬設定下，兩個選擇策略的供應鏈效能。實驗一設定四種不同的訂單需求變動環境，實驗二設定三種不同的信任傾向，實驗三設定三種不同的信任前導因素權重。
根據研究結果顯示，在訂單需求環境變化大的時候，透過信任機制來選擇供應商可以顯著的降低平均訂單週期率及顯著提升訂單滿足率。信任傾向越高，供應鏈效能越好。而信任前導因子的權重對供應鏈效能的影響則不顯著。

In this study, we seek to contribute to theoretical understanding of the effect of trust on supply chain performance under different market environments. We are aiming to design the trust mechanisms suitable for network enabled organizations (Straub and Watson, 2002) to evaluate partners’ trustworthiness on the fly of supplier choice. The sophistication of agent technologies in the future also can execute such supply chain negotiation based on the developed trust mechanisms. Before that, in this research, we use the multi-agent simulation system, Swarm, for simulating and analyzing the supply chain performance in four different market environments. Supply chain performance is evaluated using an example order fulfillment process of the mold industry to compare its performance with versus without trust mechanisms. Sensitivity analysis is used for examining the properties of the proposed trust mechanisms.
We found that the trust mechanism will reduce the average cycle time rate and raise the in-time order fulfillment rate, but increase the unit cost of materials. Higher of trustor's propensity to trust results in higher in-time order fulfillment rate. This mechanism is better than just using quote price and due date, but it raises the unit cost of materials. The range of raised cost are controlled within 3%. We can consider this 3% additional material cost as the premium of the expectation of better quality and shorter cycle time.
