Problems solved by technology

[0006] However, the biggest problem faced by the dual-code network diagram in practical application is the low efficiency of manual drawing. Affected by this, there are efficiency problems in subsequent time calculation, normative inspection, adjustment and optimization based on the double-code network diagram.

Embodiment Construction

[0046] Below in conjunction with accompanying drawing, a kind of heuristic method for automatically drawing a double-coded network diagram of the present invention will be described in detail below.

[0047] As shown in the accompanying drawings, a kind of heuristic double code name network diagram automatic drawing method of the present invention, it comprises the steps:

[0048] 1. Design a standardized Excel workbook data format

[0049] The purpose of designing a standardized data format is to enable computer programs to automatically read project or task process data in a fixed format, and then establish a standardized data structure to facilitate the automatic drawing of subsequent dual-code network diagrams.

[0050] The entire project or task process is composed of multiple processes, and each process includes attributes such as ID, name, predecessor process, duration, number of people required, major, remarks, etc. Other attributes can be determined according to actu...

Abstract

The invention provides an heuristic activity-on-arrow diagram automatic drawing method and belongs to the technical field of network planning. The automatic drawing method comprises the following steps: (1) a standardized Excel workbook data format is designed, (2) an activity-on-arrow diagram is automatically drawn, (3) a critical process is solved, and (4) an automatic layout step is performed. According to the heuristic activity-on-arrow diagram automatic drawing method, Excel workbook data is used as a data source for activity-on-arrow diagram automatic drawing. Benefits of adoption of the Excel workbook data are that isolated operation of one piece of self-made software is not needed, data input operation can be conducted via conventional general editing software, and practicality can be improved. The heuristic activity-on-arrow diagram automatic drawing method has an automatic layout function, automatic layout is a key step for activity-on-arrow diagram automatic drawing, regular layout can be realized based on a principle that the critical process should be arranged at the middle position of a whole activity-on-arrow diagram, and the regular layout is an algorithm for beautiful, concise and visualized activity-on-arrow diagram layout. According to the heuristic activity-on-arrow diagram automatic drawing method, dummy activities in the activity-on-arrow diagram are processed.

Description

[0001] (1) Technical field [0002] The invention relates to a network planning technology, in particular to a heuristic method for automatically drawing a network diagram with double codes. [0003] (2) Background technology [0004] Network planning technology is to use the form of a network diagram to express the sequence and logical relationship of various tasks, through calculation and analysis of the status of each task in the network plan, to find out the key lines, to continuously improve the network plan according to certain goals, and to select the most optimal network plan. The optimal plan, and effective control and adjustment in the process of plan implementation, to ensure the best economic and social benefits with less consumption. At present, in the engineering construction in our country, the network diagram with double codes is the most commonly used network diagram to represent the project progress plan. [0005] The advantage of the double-code network diag...
