模型库系统平台是一个独立于具体应用领域，对模型进行分类和维护，支持模型生成、存储、查询、运行和分析应用的软件系统。它是一个模型库系统的开发环境，各个领域的专家和用户都能利用它快速有效地建立其特定领域的模型库。该文提出了模型库系统平台的思想和总体框架，探讨了系统关键技术的实现以及系统的功能，并给出了模型库系统平台在海洋渔业服务领域的应用实例和效果分析。

Lacking analytical and modelling functions is widely recognized as a major deficiency of currently available GIS. Model Base System being put forward in recent years is aimed at providing powerful functions such as model management and analysis. Model Base System can be utilized to classify and maintain various models, and support their generaltion, storage, query, management and analysis.;Current research on MBS is primarily focused on specific application fields, and such systems can only be used in their specific fields. When faced with other fields, those systems need large modifications or to be developed from scratch. An economical and flexible way is to develop a general platform of MBS which experts in various fields can use to build their own model bases efficiently. In this case, we designed and developed an Osprey Model Base System General Platform. Its architecture is put forward, and the schemes of some critical techniques of the platform such as model dictionary, data interface and model-creating techniques are presented in detail. Then the main functions of the platform are outlined.;In National High-Tech Project 863-07, we built MBS for Marine Fishery Services efficiently on the Osprey Model Base System General Platform. This success demonstrates that the idea of the MBS platform is feasible. An example of model analysis-Virtual Population Analysis is also presented.
