On the discussion of network chart drawing in operational research teaching;

Convenient matrix calculation method for critical path in twin code network chart;

A note on line of vanguard of network chart of time coordinate;

A new approach to drawing double code network diagram;

Draw the method of a code number network diagram;

Study on design and implementation of network diagram of agile virtual enterprise cooperating project management software;

Automatic generation of ventilation network graph from ventilation network structural data;

The ventilation network graph is one of the important drawings in the ventilation management of the coal mines.

Based on analysis of related costs and social and economic performance of a project,calculation of time parameters of network graph and determination of critical path,LP method was used to coordinate and optimize all of sub-projects so as to maximize project construction performance in its totality.

Finding the Shortest Path in the Complex Network Based on the Advanced Dynamic Programming;

This paper presents an automatic drawing algorithm and the system realization for network.

On the base of existing methods ,we probed into the reduction method for a kind of networks whose decision alternatives had same predecessors and successors.

This article introduces the relation between thermal resistance and network figure of Heat Transfer.

By analyzing the method of drawing up classical time- coordinate network figure, the authors present a practical improved drawing method in this paper.
