By the research for the progress system main factors > target > environment motive and circulation , this paper analyzes and extracts the system core and key core of the progress in s & t of the coal enterprise , and sets up the model of coordination soft technique and hard technique system ; this paper puts forward the progress system evaluation theories in s & t of the coal enterprise and establishes the system contribution technique content > technique ability of the progress in s & t of the coal enterprise , environment evaluating index system and its evaluating model ; at the same time , the real condition of the progress in s & t of tie fa mining bureau is evaluated . this paper also analyzes the system condition and environment of the progress in s & t of the coal enterprise in china , according to the gotten system theory of the progress in s & t of the coal enterprise ; at last , on these grounds , this paper puts forward the technology development strategy of the coal enterprise in china and countermeasure thoughts that perfect the system of the progress in s & t of the coal enterprise in china 本论文基于企业科技进步主体论、系统论思想,研究了煤炭企业科技进步系统,提出了煤炭科技进步系统的概念,并通过对煤炭企业科技进步系统要素、系统目标、系统环境、系统动力和系统运行的研究,分析提炼出了煤炭企业科技进步系统核及关键核,建立了软技术系统与硬技术系统的协同模型;提出了煤炭企业科技进步系统评价理论,建立了煤炭企业科技进步系统贡献、技术含量、技术能力和系统环境评价的指标体系及其评价模型,对铁法矿务局的科技进步状况进行了实测评价;根据研究出的煤炭企业科技进步系统理论,分析了中国煤炭企业科技进步系统状况及环境,据此提出了中国煤炭企业技术发展战略和完善中国煤炭企业科技进步系统的对策思路。
Based on the analysis on the meaning and the elements of the synthesis competitive capacity of enterprises , the evaluation index system is assumed , the feasibility of carrying out fuzzy system evaluation is investigated , the maths models for fuzzy systematically evaluating are upbuilt , the synthesis competitive capacity of a large state enterprise is systematically evaluated , and analytic demonstration is provided 基于对企业综合竞争力内涵、要素的分析,构建了评价的指标体系,研究了模糊系统评价的可行性,建立了模糊系统评价的数学模型,并对一大型国有企业的综合竞争力进行了系统评价与实证分析。
Thirdly , by introducing fuzzy theory into system evaluation , evaluating student , teaching , course resource , and function of whole system . fourthly , making use of learning from examples based on information theory , machine learning algorithm is improved and machine learning decision tree is realized . finally , on reasoning mechanism , combining means of two classes reasoning is taken 第三,在系统评价中引入了模糊理论,对学生、教学、课程资源以及系统的整体功能进行了评价;第四,采用基于信息论的示例学习,改进了决策树学习算法,并建立了机器学习决策树;第五,在推理机制上,采取两级推理相结合的方法进行推理,即用基于语义网络的模糊推理确定教学序列,用基于产生式规则的推理确定教学方法,并给出了详细的推理算法。
The in - house system evaluation and field application showed that an excellent oil film for shielding temporary plugging could be formed near borehole wall and both plugging and recovering rates of permeability reached more than 90 % when the added amount of the broad spectrum oil film temporary plugging agent gpj reached 3 % ; skin factor decreased by 7 . 4 to 10 times and production increased by 1 . 82 to 2 . 96 times compared with conventional technology 结果表明,当广谱“油膜”暂堵剂gpj的加量达到3 %时,可在近井壁处形成很好的屏蔽暂堵“油膜”带,渗透率堵塞率和恢复率皆大于90 % ,与常规屏蔽暂堵技术相比,可使油层损害程度降低7 . 4 ~ 10倍,产量提高1 . 82 ~ 2 . 96倍,而且与油层渗透率和温度无关。
