【摘要】：近十年以来,随着金属矿业的快速发展以及大量资本的进入,越来越多大型集团化公司进入金属矿山开采领域。由于EPC总承包模式具有业主管理相对简单、项目的最终价格和要求的工期具有更大程度的确定性、业主的项目运作费用和承担的风险都相对降低等特点,在越来越多金属矿山新建或改扩建项目中得到应用。金属矿山行业内,较有代表性的EPC总承包商是以设计为主体的工程公司,这些公司成立时间长,具有设计经验丰富、设计专业划分精细、综合服务能力强等特点。对于以赚取利润为目的EPC总承包商而言,成本控制是其核心,设计阶段是成本控制的最重要阶段。但是,几十年以来,受DBB等传统建设模式的影响,设计人员成本控制意识不能满足EPC项目成本控制要求,设计过程中对可施工性、可采购性等其他阶段工作考虑不够充分而加大后续环节成本控制难度,因此研究设计管理模式以及能综合全面进行设计方案评价的方法,以满足EPC项目对于设计阶段的成本控制要求。本论文研究工作如下： (1)论述了金属矿山EPC项目的特点,然后采用头脑风暴法将设计阶段成本控制影响因素分类成了设计过程管理和各系统方案选择两类因素。采用专家调查法和德尔菲法对设计过程管理影响因素中的主要因素进行了分析和识别,得出工作内容分解、工作责任的划分和落实、成本控制流程3个主要因素。采用文献调查法和案例分析法,得出各系统方案选择因素中的主要因素是开拓系统的选择。 (2)采用WBS综合划分法对金属矿山项目设计内容进行分解,并对子项和分项进行了编码。根据WBS后的工作内容,设置了适合金属矿山EPC项目设计阶段成本控制的复合型项目组织结构,对工作责任进行划分,并对参与设计和设计管理的人员进行了编码。结合子项编码和人员编码,根据综合职责分工矩阵原理,得出综合职责分工表,工作责任得以落实。在工作任务分解和工作责任划分、落实的基础上,设置了适合金属矿山EPC项目设计阶段的成本控制流程。通过某铁矿山EPC项目的案例分析,验证了WBS综合划分法的有效性,验证了复合型组织结构合适性,验证了综合职责分工矩阵的可行性,验证了成本控制流程的合理性。 (3)通过分析开拓系统方案选择过程中常有方法的不足,提出了适合综合评价开拓系统方案的模糊综合评价法。通过某铁矿EPC项目开拓系统方案的案例分析,验证了该方法的合理性和可行性。
[Abstract]:In the past ten years, with the rapid development of metal mining industry and the entry of a large amount of capital, more and more large conglomerate companies have entered the field of metal mining. Because of the relatively simple management of the owner, the greater certainty of the final price and the required duration of the project, and the relatively low cost and risk of the project undertaken by the owner, the EPC general contracting mode is characterized by a relatively simple owner's management. It has been used in more and more new or extended projects of metal mines. In the metal mine industry, the representative general contractor of EPC is the engineering company with design as the main body. These companies have the characteristics of long time, rich experience in design, fine division of design specialty, strong comprehensive service ability and so on. For EPC general contractor, cost control is the core, and the design stage is the most important stage of cost control. However, due to the influence of traditional construction mode such as DBB for decades, the cost control consciousness of designers can not meet the requirements of EPC project cost control. Other stages, such as procureability, are considered insufficiently to increase the difficulty of cost control in follow-up links. Therefore, the design management model and the method for comprehensive evaluation of design schemes are studied. To meet the EPC project design phase cost control requirements. The research work of this thesis is as follows: This paper discusses the characteristics of EPC project in metal mines, and then classifies the factors of cost control in design stage into two kinds: design process management and system scheme selection by using brainstorming method. The main factors of design process management are analyzed and identified by using expert investigation method and Delphi method. Three main factors including work content decomposition, job responsibility division and implementation, and cost control flow are obtained. By using the method of literature investigation and case analysis, it is concluded that the main factor in the selection of system scheme is the choice of developing system. (2) the design content of metal mine project is decomposed by WBS comprehensive partition method, and the sub-items and sub-items are coded. According to the work content after WBS, the compound project organization structure suitable for the cost control of EPC project design stage in metal mine is set up, the work responsibility is divided, and the personnel involved in the design and design management are coded. Combined with sub-item coding and personnel coding, according to the principle of comprehensive division of duties matrix, the comprehensive duty division table is obtained, and the work responsibility can be carried out. On the basis of the decomposition of work tasks and the division of work responsibilities, a cost control process suitable for the design phase of EPC project in metal mines was set up. Through the case analysis of a EPC project in an iron mine, the validity of the WBS comprehensive partition method is verified, the suitability of the compound organizational structure is verified, the feasibility of the comprehensive division of responsibilities matrix is verified, and the rationality of the cost control process is verified. 3) by analyzing the shortcomings of common methods in the process of developing system scheme selection, a fuzzy comprehensive evaluation method suitable for comprehensive evaluation of development system scheme is put forward. The rationality and feasibility of this method are verified by a case study of EPC project development system in an iron mine.
