艰险山区铁路工程技术接口管理协同度研究OA
Research on the Coordination Degree of Railway Engineering Technology Interface Management in Difficult Mountainous Areas
为解决艰险山区铁路工程不同参与方之间的冲突、进度延误等问题,实现资源的高效利用,提高技术接口的管理水平,将管理协同思想引入铁路工程技术接口管理,从序参量有序度、子系统有序度、系统协同度 3 个方面构建铁路工程技术接口管理协同度评价模型.首先,选取铁路某标段工程作为研究对象,在对铁路工程系统进行细化分解、识别技术接口的基础上,从内外部环境分析铁路工程技术接口管理协同的复杂性,为铁路工程技术接口管理协同系统的构成奠定基础.其次,基于铁路工程技术接口管理协同系统的构成要素,通过文献查阅、专家咨询等方法建立技术接口管理协同度评价指标体系.最后,运用改进的层次分析法确定各级指标的权重并计算出技术接口管理在规划、分析、设计、实施、验证、运维 6 个阶段的系统协同度,分析接口管理系统协同度水平的变化情况,并提出相应的协同度提升策略.结果表明:铁路某标段工程验证阶段的协同度最低为-0.014 383,实施阶段的协同度最高为 0.018 856,6 个子系统的整体协同度呈上升趋势.这一结论表明评价模型可操作性强、结果可靠,可为铁路工程技术接口的协同管理提供新的视角.
In order to solve the problems of conflict and schedule delay between different participants of railway engineering in difficult and dangerous mountainous areas,realize the efficient utilization of resources and improve the management level of technical interface,the idea of management synergy is introduced into the management of railway engineering technical interface.The evaluation model of synergy degree of railway engineering technical interface management is constructed from three aspects:order parameter order degree,subsystem order degree and system synergy degree.Firstly,a certain section of railway project is selected as the research object.On the basis of detailed decomposition of railway engineering system and identification of technical interface,the complexity of railway engineering technology interface management collaboration is analyzed in terms of internal and external environments,which lays a foundation for the composition of railway engineering technology interface management collaboration system.Secondly,based on the elements of railway engineering technical interface management coordination system,the technical interface management coordination degree evaluation index system is established through literature review,expert consultation and other methods.Finally,the improved analytic hierarchy process is used to determine the weight of indicators at all levels and calculate the system synergy degree of technical interface management in the six stages of planning,analysis,design,implementation,verification,operation and maintenance,the changes of the synergy level of interface management system are analyzed,and the corresponding synergy promotion strategy is put forward.The results show that the lowest synergy degree in the verification stage of a railway section project is-0.014 383,the highest synergy degree in the implementation stage is 0.018 856,and the overall synergy degree of the six subsystems is on the rise.This conclusion shows that the evaluation model has strong operability and reliable results,which can provide a new perspective for the collaborative management of railway engineering technology interface.
