Abstract


With the rapid development of information technology , information science research field Earth constantly widening , depth increasing, which effectively promoted the science of information technology resources and environment . However, resources and environment model complexity , diversity , technology is also an urgent need for large-scale model of a rich computing resources , standardized and unified space for data storage and communications, data integration and expression techniques. Firstly, the model , the model database management system, integrated modeling environment , resources and environment models related concepts , architecture, and made ??a presentation and discussion of the theory . Then, from the construction and expression of the model , the model and the model compound angles of the key technologies for modeling framework and theoretical analyzes . Thesis focused on the environment modeling framework design method conducted in-depth research , and implemented based on resources and the environment workflow modeling framework , the final application modeling framework to build grassland ecosystem food supply model , the case proved the feasibility modeling framework . Main work and arguments are as follows: ( 1 ) paper discusses the expression of the model , build, and management. And designed XML-based resource environment model and the model expression multiplexing method and object-oriented design methods abstract representation of the model , and based on the idea of ??workflow modeling environment for expansion. ( 2 ) proposed a new model based on MathML formulas parsing and escape methods, through semantic markup language for mathematical analysis to dynamically build a model instance. Compared to traditional methods, namely resources and environment model abstract model class and model instance that this method is more flexibility , practicality and scalability , no need for the expansion of various models and programming and design. ( 3 ) This paper proposes a formal description of the model composite mode method , and apply it to simplify the model symbol sequence for optimization modeling environment has laid a theoretical foundation. ( 4 ) paper designed a modular structure modeling environment , which greatly facilitates the expansion of new features . And components in the system to a more integrated way data preprocessing and post-processing modules.
