基于角色的LCC控制知识地图构建

Building Knowledge Maps of Life Cycle Cost Control Based on Roles

运用系统工程原理完成产品全生命周期成本(LCC)目标的分解,建立了目标与任务的映射、角色与任务的匹配、任务与消耗资源的关联、角色所执行的任务与知识需求的关系。研究了LCC控制目标的实现机制,提出面向LCC控制的知识地图概念模型,采用本体技术构建基于角色的知识地图。通过领域本体开发、知识组织与描述,生成适用于不同角色的五种LCC控制知识地图。

Using system engineering principle,this paper decomposes the goal of product life cycle cost(LCC) and establishes the map of goals and tasks,the match between roles and tasks,the relevance of tasks and resources consumed,and the relationship between knowledge requirements and tasks which the roles perform.Meanwhile,the realization mechanism of the goal in LCC control is discussed.This paper also puts forward a conceptual model of knowledge map oriented LCC control and builds the knowledge maps based on roles by using ontology technology.Finally,this paper generates five knowledge maps to face different roles,with domain ontology development as well as knowledge organization and description.
