在渔船备件费用灰色预测的基础上，结合马尔可夫链预测方法，建立渔船备件费用灰色马尔可夫预测模型，该模型兼有灰色预测和马尔可夫链预测的优点。实例计算证明，渔船备件费用灰色马尔可夫预测模型的预测精度高于灰色预测模型预测精度，模型可以用于渔船备件费用预测。
在漁船備件費用灰色預測的基礎上，結閤馬爾可伕鏈預測方法，建立漁船備件費用灰色馬爾可伕預測模型，該模型兼有灰色預測和馬爾可伕鏈預測的優點。實例計算證明，漁船備件費用灰色馬爾可伕預測模型的預測精度高于灰色預測模型預測精度，模型可以用于漁船備件費用預測。

The grey-Markov model for the expense forecast of spare parts of fishing boats is built in this paper, based on grey method of forecast and combined with the Markov chains forecast. This model has merits of both grey forecast and Markov chains forecast. The example shows that the precision of grey-Markov model for the expense forecast of spare parts of fishing boats is better than that of grey model. This model can be used for the expense forecast of spare parts of fishing boats.
