【摘要】：经济的进一步融合使企业之间的竞争由以前点对点的竞争转变为由客户、供应商、研发中心、制造商、经销商和服务商等合作伙伴组成的供应链网络之间的竞争。今天,拥有完整强大的供应链即意味着拥有强大的竞争力。建材装备制造业作为装备制造业的重要组成部分,其发展水平是一个国家的整体工业水平的重要体现,也是我国优先发展、并上升到了战略层面的产业。处于价值链顶端的建材装备制造业附加值高,带动作用强,与多个行业具有紧密关系。在当前我国所处的背景下,建材装备制造业的重要性更为明显。处于整条供应链核心地位的建材装备制造企业的竞争力直接影响到整条供应链的竞争力。以供应链的思想对单个制造企业的运作方式进行研究,对于提高整条供应链的竞争力有着重要意义。企业内部供应链强调企业内部各个部门之间的协调,可以看作是外部供应链的缩小化。核心企业部门之间、核心企业与供应商之间、核心企业与外协厂商之间存在的频繁的信息流、资金流和物流直接影响企业供应链运作。论文以建材装备制造企业为背景,研究了在供应链角度下企业的运作方式和供应链流程优化问题,主要研究内容及工作如下:(1)分析了供应链思想对提高建材装备制造企业竞争力的重要性,对建材装备制造企业的生产过程进行了一般化的过程梳理,将企业的各个部门当作供应链上面的参与元素。(2)利用Petri网建立了建材装备制造企业的供应链模型,并对模型进行正确性验证。引入了时间约束,建立了其随机Petri网(SPN)以及其同构马尔科夫链,分析了模型中变迁的利用率和整个模型的响应时间等各项性能并基于关联矩阵的重组算法对模型进行子网划分并优化。(3)通过对模型的性能分析,指明了流程优化的方向并进行了模型修正。从时间性能角度对新模型进行评价,并结合敏捷供应链的思想,在新模型的基础了加入了生产计划变更的情况,提高了模型的动态性能。(4)在理论研究的基础上,开发了基于随机Petri网的建材装备制造企业供应链管理信息化平台,并对主要模块进行了设计,实现了企业内部供应链上资源共享,信息化管理平台已经在唐山某企业中得到了应用,取得了预期效果。
[Abstract]:The further economic integration of the competition between enterprises is changing from the previous point of competition for customers, suppliers, manufacturers, R & D center, between dealers and service providers and other partners in the supply chain network competition. Today, complete with a strong supply chain means have strong competitiveness. An important part of building materials and equipment as the manufacturing industry of equipment manufacturing industry, its development level is an important manifestation of a country's overall industrial level, but also give priority to the development of our country, and rise to the strategic level of the industry. At the top of the value chain of building materials and equipment manufacturing industry with high added value, strong leading role, has a close relationship with multiple industries. The background of our country, the importance of building materials and equipment manufacturing industry is more obvious. In the whole supply chain will directly affect the competitiveness of the core status of building materials and equipment manufacturing enterprises to the whole. Supply chain competitiveness. With the idea of supply chain of manufacturing enterprises on a single mode of operation, has great significance for improving the competitiveness of the whole supply chain. The internal supply chain emphasizes the coordination between various departments within the enterprise, can be regarded as the external supply chain reduced. Between the core enterprise departments, between the core the enterprise and the supplier, between the core enterprise and the outsourcing vendor frequent information flow, capital flow and logistics enterprises directly influence the operation of the supply chain. The building materials and equipment manufacturing enterprises as the background, the research in the perspective of the supply chain under the mode of operation of the enterprise and the supply chain optimization problem, the main research contents and work are as follows: (1) analysis of the importance of the thought of the supply chain to improve the building materials and equipment manufacturing enterprises, the production process of building materials and equipment manufacturing enterprises of the general Cheng Shuli, Each department of the enterprise supply chain as part of the elements above. (2) is established by using Petri net model of supply chain building materials and equipment manufacturing enterprises, and verify the correctness of the model. The introduction of the time constraints, establishes the stochastic Petri net (SPN) and its isomorphic Marco Markov chain, analyzed by response time the rate and model the performance of model change and restructure the matrix based algorithm for subnetting and Optimization Based on the model. (3) through the performance analysis of the model, pointed out the direction of process optimization and model modification. To evaluate the performance of the new model from the time point of view, combined with agile the idea of supply chain, the production plan to change the situation of join in the basis of the new model, to improve the dynamic performance of the model. (4) on the basis of theoretical research, the development of the building materials equipment manufacturing enterprises based on stochastic Petri net The information platform of supply chain management has been designed, and the main modules have been designed. The resource sharing inside the enterprise supply chain has been realized. The information management platform has been applied in an enterprise in Tangshan, and achieved the desired results.
