A Farm Firm Model of Machinery Investment Decisions
提出一个多期混合整数规划模型，用于优化农机投资决策，通过模型的对偶性质识别和评估机会成本，强调从企业整体视角分析投资策略，并用实例演示应用。
Abstract This article presents a multiperiod mixed integer programming (MMIP) model of optimal machinery decisions. Infinite horizon valuation models of replacement and other investment situations are conceptualized in the context of a finite programming model. Dual properties of the MMIP model are used to identify and value opportunity costs involved in investment decisions of farm machinery. The interdependent nature of investment and production relationships necessary for solving these values emphasizes the importance of a holistic firm perspective in analyzing farm machinery investment strategies. An empirical situation is used to demonstrate model application.
