Teamwork-oriented integrated modeling method for geo-problem solving

摘要

Currently, studies on constructing integrated modeling solutions in a web-based environment primarily focus on the chaining of different model-services, while the flow of exploring solutions for complex geo-problems - geographically distributed issues - has been less studied. To address this gap, a teamwork-oriented integrated modeling approach to supporting geo-problem solving based on the collaborative work of different modelers is proposed in this article, with a workflow from conceptual, logical, and finally, computational modeling. In this approach, conceptual, logical and computational models are discussed and constructed using a graph-based method, a flowchart-based method and a service-configuration-based method, respectively. By building the corresponding repositories for managing and comparing different versions of conceptual-logical-computational models, dispersed modelers can propose their own ideas and explore appropriate solutions based on existing modeling resources. A prototype modeling system was established, and two experimental modeling cases were conducted to verify the feasibility and capability of the proposed approach.
