就經濟學觀點，價格是市場上許多決策的依據，也是調節供需「一隻看不見手」。當一產品在市場上供給量大於需求量時，假設其他情況不變，價格會下降；反之價格會上昇。但實際上影響供給及需求的因素很多，且這些因素多有具連動性，會造成飼料價格的變動。本研究再以飼料商、養豬戶間，因飼料價格的變動產生“朦懞市場“飼料價格差異性大而設限；由於我國為海島型的國家，在貿易進口與出口之經貿發展實為重要，穀物的供需危機，小麥、玉米、黃豆這三樣最基本的大宗物資在近年價格齊揚，可說是為高糧價時代揭開序幕。 本研究以毛豬飼料價格預測為標的，採用近年來廣為應用的類神經模糊網路做為預測模式並與預測飼料價格常用時間序列預測模式比較，以期找出更有效更精確的價格預測模式。資料期間為民國88年1月至民國98年1月資料為月資料，以期分別衡量模式的預測能力。 Economics point of view，Price are many policies 's basis on market ，Also is regulating supply and demand 「A looks disappear hand 」。Ases a product at market on supplies quantity be more than demand time ，Supposes other situation not change ，Price can descend ；Vice versa price can rise。But actually affects supply and requirement's factor many ，And these factors many have move sex，Will result in feed pricing alteration 。This researches again as feed business 、Between swineherd ，Because feed pricing alteration bring forth “ Mang meng market “Feed price otherness big but set up limit ；Because our country for island type 's country ，At trades import with export of economy and trade develop be really important ，Corn's supply and demand crisis ，Wheat, Maize, Soya this three kinds of more basic a large amount material at recent years price neat Yang ，Can say be be high grain price era open prelude 。 This researches as live pig feed price forecast for article ，Adopts in recent years widely application's kind nerve ambiguous network do for forecast model and with forecast feed price in common use time series prediction mode comparation ，Ins order to seek come out more effective much precise price forecast model measure mode comparation 。Is the people country 88 year one month to the Republic of China 98 year one month data for month data course data, Ins order to difference measure mode 's forecast ability 。
