工业企业设备的更新是社会生产发展和技术进步的客观要求.本文试用动态规划原理研究以备更新最佳期限的策略,提出了两种条件下的动态规划模型,即不考虑技术进步的设备更新动态规划模型和考虑技术进步的设备更新动态规划模型,建立了设备状态决策方程和经济效果评价方程,并结合实例演算,得出了设备更新的最优策略.

The renewal of industrial enterprise equipment is an objective requ-irement of social productive development and technical progress.This paper studies the optimal time strategy of the renewal of equipment by means of the Dynamic Programme Method.It puts forward models under two different kinds of condition: one being a model of Dynamic Programme of renewal of equipment without technical progress, the other being that with technical progress, we also set up formulas of equipment state and econ-omic effect appraisement, make calculations with some real examples, and finally obtain the optimal strategy of equipment renewal.
