Research ArticleOpen accessIn the keywordsPetri Net Based Spatio-temporal Relationships for Moving ObjectsYong-shan Liu, Zhong-xiao HaoThis study presents the spatio-temporal constraint relationships of moving objects by employing Petri Net technology. The spatial constraints of moving objects are first presented in this study based on the V4I[1] theory, then the temporal constraints for moving objects are presented by applying this theory to temporal aspect. With the proposing of Moving Object Petri Net (MOPN) and Spatial Constraint … …Journal of Computer Science, Vol. 1, Issue 4 · 31 Dec 2005 · 6,235 accessesView PDFCite
