摘要
在许多分布问题的管理操作中,需要同时对车辆的运行路线进行人工和自动控制、操作和管理。建立计算机化的公路网络,主要应考虑如何迅速显示图形,以便进行控制、操作及管理。管理人员将依靠这个计算机化的公路网络来执行一系列的决策支持功能. 这些功能将大大增强最优解的有效性和可接受性,并增强了管理人员的信心. 本文发展了一个图形显示和控制操作管理系统,它适用于很大的公路网络,可达近千个节点和近千条'弧',可在普通的IBM-PC机上实现上述功能. 同时,本文提出一个简化的模型描述在IBM-PC机上执行上述功能的软件.
In many distribution operations display and manipulation must be considered both in manual and automatic routing of vehicles. For establishing a computerized road network, we must mainly take a quick graphic display into account in order to display and manipulate the network easily. The scheduler depends on this network display for a number of decision support functions. These facilities enhance significantly the effectiveness and acceptability of solutions produced by any vehicle routing optimization system, and instil confidence in the scheduler. This paper develops a graphical display and manipulation system that can accommodate very large road networks-----of the order of nearly thousand nodes and arcs, and provides the above mentioned facilities on an ordinary IBM-PC. This paper presents a simplified model as well to describe a software on IBMPC.
