针对现有的网络计划模型重点体现的不是其核心机动时间和路差,而是具体的时间和路长,进而使得该模型在运用时往往会遇到阻碍的问题,利用对偶原理,构建网络计划模型的对偶模型.首先,通过分析机动时间和路长之间的关系,推导出路差定理;其次,在路差定理的基础上,利用对偶原理构建对偶网络模型,并分析其性质;然后利用该模型揭示网络计划的对偶等价性;最后,通过例子进行验证和说明.该对偶网络模型重点体现了机动时间和路差,使得网络计划更具针对性和有效性.
The existing network planning model focuses not on the core maneuvering time and road difference, but on the specific time and length of road, which makes the model often encounter obstacles in the use of the use of dual principles to build a network plan Model.Firstly, by analyzing the relationship between maneuvering time and road length, the road-difference theorem is deduced. Secondly, based on the road-difference theorem, the duality network model is constructed based on duality principle and its properties are analyzed. Then, The model reveals the dual equivalence of the network plan.Finally, the example verifies and illustrates the dual network model, which emphasizes the maneuver time and path difference, which makes the network plan more specific and effective.
