本文介绍将平行线路作为一个系统加以研究,在充分考虑其能力加强与货流分配二者相互联系的基础上,提出了解决平行线路能力加强问题的分层优化方法。其中,着重研究了在系统加强方案已知条件下的平行线路能力加强的数学模型,并对这一多变量、非线性、多重组合的动态规划问题提出了新的求解方法——动态试探法。
In this paper, parallel lines are studied as a system, and on the basis of full consideration of the interrelationship between its ability and distribution of goods flows, a hierarchical optimization method is proposed to solve the problem of strengthening capacity of parallel lines. In particular, the mathematical model of strengthening the parallel lines under the known conditions of the system reinforcement scheme is emphatically studied, and a new method for solving the dynamic programming problem of multivariable, nonlinear and multiple combinations is proposed - the dynamic heuristic method.
