Research On Schedule Planning And Control Of SG Galvanized Line Roller System Renovation Project

21st century, the world economy has undergone profound changes, with the knowledge economy era, the economic pace of globalization, global competition is increasingly fierce, unpredictable changes in the market, the increasingly volatile. Played a key role in a competitive environment, project management, project management application surface are constantly in-depth understanding of project management concepts and methods.Iron and steel industry as an important manufacturing sectors of the national economy, the impact of macroeconomic and steel industry downstream demand, many steel mills are facing meager profits or losses. Upgrading the production line, has become a bottleneck in the development of the iron and steel enterprises in China. How to use project management ideas and technology to solve the defects of the original design, in order to increase production, expand the variety and improve accuracy, improve the degree of automation is a subject worthy of further study.SG galvanized production line with the debug operation of the equipment, two units, the exit section of the original design without tension take-up, resulting in strip production process and support the issue of title of the table friction and resilience to stand out. Serious impact on galvanized sheet steel strip surface quality and rating on the one hand, or even scrap; the other hand, reduces the efficiency in the use of production equipment, can not guarantee the accuracy of the function, or even result in security vulnerabilities and security incidents. Therefore, the urgent need for the unit’s roll subsystem transformation and optimization.Using the technology of project management WBS to decompose the project, design project management organization and matrix organization of the division of responsibilities, the compatibility of the functional organization of the longitudinal strengths and advantages of horizontal management of the project organization to achieve management innovation, and give full play to the collaboration capabilities. Estimation method in the scheduling process, expert judgment and analogy, to determine the duration of relatively precise activities, there is great uncertainty for the duration of the activity is estimated three time (optimistic time, the most likely time pessimistic time), weighted based on normal distribution theory, critical path method and PERT integration to solve the preparation of project schedule estimates encountered in a matter of time. In progress control, the application of dynamic loop closed PDCA theory, check the deviation of the actual progress and planned progress, analyze the reasons for the deviation may appear to take corrective ensure achievement of project objectives. Combined with the characteristics of the reconstruction project, the proposed protection measures to achieve progress.According to the characteristics of the transformation of iron and steel industry projects to construct a feasible schedule, the implementation of the control program template for similar projects in the implementation process reference.
