台灣地區花卉最適運銷量之決定：兼論採行遠端拍賣之可行性

The Determination of the Optimal Flower Distribution in Taiwan : With A Discussion on Feasibility of Implementing the Remote Auction System

本研究以民國86年12月國內四家花卉批發市場交易檔資料作為資料來源外，並選定前十大花卉品項，分別為康乃馨、火鶴花、大菊、小菊、非洲菊、葵百合、劍蘭、香水百合、玫瑰及姬百合，作為分析對象，利用數學規劃模式，而在追求整體花農效益最大的目標下，考慮各批發市場的拍賣價格及運費，各縣市之花卉應如何轉運，使其既能滿足各縣市之需求，又能使整體花農效益極大，以提高農民所得。模式執行結果顯示在最佳運銷量調配下，台灣地區花農總體最大效益約為1.7億新台幣。四家花卉市場各有其服務特色，民國86年12月期間，進口數量最多的花卉品項為火鶴花，且主要供應量不足之地區為台北市，因此，花農可多搜集些資料以決定是否要多種些火鶴花，以供應台北市。最佳解中各花卉市場的供應人較集中於某些縣市，而非如現況散佈於台灣西岸各縣市。而在承銷人方面，最佳解與現況較無顯著差異。其次，本文也將討論此規劃結果在遠端拍賣制度下落實之可行性。

The purpose of this research is to build a mathematical model. The model is designed to determine the optimal bunch of flowers to be shipped from each wholesale market to each county in Taiwan flower industry. The objective of this mathematical model is to maximize the income of the whole Taiwan flower industry. The factors considered in this research include: auction price, logistics cost, supply and demand quantity of each type of flower in each county. The result shows that each flower wholesale market has a very clear position (e.g., Taichung flower wholesale market is a local market, mainly, serving Taichung county). Also, in the optimal solution, suppliers of each flower wholesale market will be located in several counties only. But, buyers may come from different counties in Taiwan, The contribution of this paper are twofolds. One is to provide the optimal decision in terms of how many bunches of flowers suppliers in a county should ship from his county to another one. The other is to know the situation of demand and supply quantities. For example, the domestic supply of Flamingo Flower (FF) is insufficient. Therefore, we know we need to import FF from other countries. Also, in this paper, we discuss the feasibility of implementing the optimal result of the mathematical model in remote auction system.
