Exploration of a calculation system of drawing quantity with 'read schemata'

摘要

To solve the problem of "reliablity", calculation scope and the high thresholds in the operation of the graphics automatic calculation quantity system in the practical use, "read schemata" graphics calculation quantity technology is analyzed. This technology has the features of direct visualization, clear presentation, no requirement for memory in work, revisability, meeting cost engineer's work habits, low threshold in operation, wide application scope, easy proofreading and so on. The axis module algorithms and information structure are given. The experimental results show that this method is effective, feasible and superior to other graphics quantity calculation system. Finally, further research problems are presented, such as the structure of knowledge base, calculation rule set and so on.
