Abstract:	現今，企業與企業之間已從相互競爭朝向彼此合作的關係，供應鏈成員需以整體利益作為最優先決策考量。隨著資訊科技不斷地發展，供應鏈已開始透過有效的資訊交換與處理，使上下游關係更為緊密。不過大部份的企業並不願意在未知任何好處的情況下主動分享資訊給合作夥伴，因此，本研究針對資訊分享的議題進行討論，並進一步評估資訊分享將帶來的效益，使企業願意進行資訊分享。不同以往各學者僅以成本角度分析資訊分享的效益，本研究除以模擬工具建構資訊分享下之供應鏈架構模式，並在模式中加入利潤的觀點。利用實驗設計探討在不同的平均需求d、需求自我相關係數 ρ、需求波動性 σ、製造商利潤率P、製造商單位缺貨成本 Π 、製造商單位持有成本 H 、零售商單位缺貨成本 π 及零售商單位持有成本h，對供應鏈中之製造商在資訊分享相較於無資訊分享之總利潤上升比率影響情形。並針對各因子在不同水準及因子兩兩交互作用之情境下，對製造商在資訊分享相較於無資訊分享總利潤變化情形，進一步探討製造商是否可分享合理的利潤給零售商以激勵零售商分享資訊的意願。本研究實驗結果發現，需求自我相關係數及需求波動性越強時，資訊分享越能產生其價值性。研究發現雖然資訊分享確實能對製造商總利潤有提升的情形，但在某些情況下資訊分享並不會顯著的為製造商帶來額外的利潤，因此，零售商在分享資訊後，應在合理的範圍內對製造商提出利潤分享要求，才能使彼此達到共同獲利且長期合作的關係，且製造商利潤率對製造商在資訊分享相較於無資訊分享總利潤上升比率之影響並非最關鍵因素，因此，零售商在分享資訊後，不應以製造商利潤率的多寡來提出利潤分享的要求。此外，在資訊分享下，製造商需特別注意環境因子的變動可能會提高/降低原先資訊分享帶來的成效。 Nowadays, the relationships among enterprises relationship have been changed from competition to collaboration. The overall benefit of the supply chain is a top priority consideration for decision-making by members. With the advance of information technology, members of the supply chain are closely together through effective information exchange and processing making between the upstream and downstream partners. Hence, information sharing is a very important issue. Most companies are not willing to share information actively to their partners if they do not know any benefits produced by information sharing. In this study, we discussed the issue of information sharing and further quantify the benefits of sharing information so enterprises are willing to share information.Different from past analysis most scholars discussed benefit of information sharing only from the viewpoint of the cost. In this study, we will build the supply chain information sharing model by simulation and add the viewpoint of the profit. The experimental design is explored to discuss whether or not the following factors will significantly affect total profits rise ratio of manufacturer in information sharing compared to no information sharing: average demand d, demand self-correlation coefficient ρ, demand volatility σ , profit margin of the manufacturer P, unit shortage cost of manufacturer π, the unit holding cost of manufacturer H, unit shortage cost of retailer π and holding cost of retailers h. In addition to analyzing main effect of each factor, the interaction between two factors is also addressed. This study further explores whether the manufacturer can share reasonable profits to its retailer and encourage the retailer to share the information. The results show that information sharing can produce more profit with highly self-correlation coefficients, highly variable. This study also finds that although information sharing actually enhances the total profits of the manufacturers, but in some cases, there is no significant profit gain for manufacturers by information sharing. Thus, the retailer can request a reasonable profit through information sharing in order to achieve common benefits and long-term cooperative relationship. And the profit margin of manufacturer is not the critical factor that effect the total profits rise ratio of manufacturer in information sharing compared to no information sharing. Therefore, the amount which the retailer can request is not based on manufacturer profit margin after the retailer shares the information. In addition, manufacturers need to pay attention to dynamic environment which may increase or reduce the original effectiveness of information sharing.
