    摘要:

    提出了農(nóng)業(yè)機械導(dǎo)航系統(tǒng)多指標(biāo)評價模型，將導(dǎo)航成本、精度、適應(yīng)能力、穩(wěn)定性和計算復(fù)雜性作為評價指標(biāo)，采用層次分析法和信息熵相結(jié)合的方法確定各指標(biāo)權(quán)值，具有兼顧主觀和客觀賦權(quán)的優(yōu)點。建立了神經(jīng)網(wǎng)絡(luò)并訓(xùn)練模型形成評價系統(tǒng)。通過數(shù)據(jù)分析表明，該綜合評價方法克服了人為因素的影響，評價系統(tǒng)使用簡單方便。

    Abstract:

    The multi-index evaluation model of agriculture machine navigation system was proposed, and the cost, accuracy, adaptability, stability and computing complexity were used as five indexes which mainly affect the navigation system performance. The weight of each index was decided by combining AHP and entropy method, which has the advantages of subjective and objective. The RBF neural network was used to build the evaluation model. Data analyses showed that the method was easy to use, and overcomed the influence of subjective factors.
