Yanlian Sec Butyl Acetate Project Schedule Optimization Research

China from the mid-1960 s the introduction of network planning techniques, although the technology has been used in some of the trans better large construction companies and large-scale projects, but there is no real scientific use in a considerable part of the project, failed to give full play to its management efficiency, resulting in the project behind schedule, project management and control target difficult to achieve. In recent years, project construction work Yan’an Refinery also present more prominent issue behind schedule, restricting the company’s development speed and economic efficiency.In order to reduce production costs, extend the product chain, to create economic benefits, Yanchang Petroleum Group in Yan’an Refinery launched 70,000 tons / year acetic acid butyl project, but the project in the construction process, exposing the project schedule control is not strong project schedule management unscientific, project schedule control deficiencies and other personnel issues, so the project schedule management butyl acetate research has important significance.In-depth progress of the status quo, existing problems of analysis on the progress of management theory paper uses network planning technique, Critical Path Method, etc., prepared schedule, for the duration, resource allocation is optimized for the project on schedule to promote the creation of the conditions. At the same time, choose to take effective tools, methodologies, project construction schedule to control. Application of earned value method, from a cost, schedule both evaluate project implementation to achieve the dynamic management of the project schedule.In this paper, network planning techniques and earned value method is applied to engineering practice, through the office project 2007 sec-butyl acetate as an auxiliary software project progress control, improve efficiency, achieve shorter project duration, balanced configuration resources.
