AbstractThis paper mainly focused on cotton pickers life cycle cost (LCC) calculation based on dynamic analysis. Life cycle cost data of cotton pickers were collected by enterprise survey and references. Uncertainty factors of cotton pickers life cycle cost was labor cost and oil price. Then using simulation methods, we analyze different cotton pickers LCC and profit under oil price variation in Xinjiang. Because of different charge mode in Xinjiang, this paper analyzes cotton pickers profit variation trend under per unit yield of cotton in southern Xinjiang and charging standard improving in northern Xinjiang. Finally, the conclusions were proposed: because agricultural machinery service companies (AMSC) earnings in southern Xinjiang are higher than in northern Xinjiang, southern AMSC use domestic cotton pickers are not more positive than northern AMSC. However, with service price improving, northern AMSC will decrease using domestic cotton pickers. With per unit area yield of cotton increasing, economic benefits of southern AMSC become better than northern AMSC. Oil price and labor cost increasing can not affect cotton pickers application.
Key word: Life cycle cost; cotton pickers; dynamic cost; uncertainty
