摘要:
针对信息资源配置问题提出了一种基于有色Pet ri 网的规范化建模方法, 并对整个建模 过程进行了详细的描述. 提出了系统层次模型结构和执行图的概念, 对执行图和Pet ri 网之间 的转换过程进行了分析、定义, 从而减少了大系统建模的复杂程度和工作量. 利用相关的计算 机工具, 可以方便地实现系统建模和对信息资源配置情况的评价、分析和调整
Abstract:
Th is wo rk is devo ted to a dynam ical modeling m ethod of resou rce allocat ion fo r info rm at ion system s based on co lou red Pet ri net s. The m ethod can be u sed in the mo re comp lex en terp rise info rm at ion system s. The def in it ion s of system h ierarchy model and execu t ion graph are p ropo sed. System developers can pay mo re at ten t ion on differen t level of the model acco rding to their concern. A nd the t ran sfo rm at ion m ethod betw een execu t ion graph and pet ri net are analyzed. Based on the p ropo sed dynam ical h ierarchy model, system developers can evaluate the system dynam ical perfo rm ance and adju st the resou rce allocat ion of info rm at ion system s to m eet the perfo rm ance requ irem en t. The modeling p rocess of info rm at ion system s is given in detail. A nd app licat ion examp le is p resen ted.
