摘要

在現今資訊的時代當中，企業電子化(E-business) 讓企業虛擬與實體的營運活動連結得更為緊密，使得價值鏈的活動更為即時。透過電子化交易加速供應鏈的流程運作，已經是產業保持競爭優勢的基本要求，所以在供應商評選階段導入候選供應商的電子化程度，無形當中可以縮短交易的進行時間與減少採購上的成本支出。故本研究在遴選供應商時將電子化程度視為一重要指標，並在考量運輸成本、採購成本及供應商固定成本外，再配合不同的數量折扣策略進行決策，建構一非線性的整數規劃模式。此外，由於各供應商皆有其資源的限制，所以在進行料件採購時，就必須了解各供應商的產能限制，以降低因為供應商無法出貨而造成缺貨的風險，因此本研究考慮各供應商的產能限制來分配需求量，所以最終所求解出的為一組供應商組合及數量的配置，避免因供應商產能不足所帶來的缺貨狀況。為了能有效求解本研究所提出的數學規劃問題，最後階段將以粒子群最佳化( Particle Swarm Optimizer；PSO)演算法來求解此一考量供應商電子化程度以及成本評估因素的供應商遴選及數量分配問題。

With the rapid progress of information technologies, there is a growing demand of maintaining the competitive advantages by accelerating the supply chain process through E-commerce. This paper analyzed an approach to shorten the transaction time and reduce the purchase cost by means of Internet-based selection of suppliers. While E-commerce was taken as an important index in the selection of suppliers, the cost factors along with quantity discount policies were considered for decision-making. In order to reduce the possible shortage of raw materials, an integer programming model was constructed to solve the problem in consideration of the e-commerce of suppliers, selection of suppliers and quantity allocation based on cost evaluation factors. Finally, this problem was solved through Particle Swarm Optimization (PSO).
