Along with information technology and globalization, whether government, corporate or personal, in the 21st century is facing increasingly fierce competition, continue to seek a competitive advantage has become more and more organizations choose to start a variety of projects ; many repetitive action being more and more automated machinery and equipment replaced. So, it was said that the 21st century is a project-oriented society, \Construction project managers as communication, in numerous transaction handling, to sort out the main and secondary contradictions, principal contradiction is the fundamental principle to solve the problem of time management. The goal of the project time management is the progress of the project goals smoothly. Construction project can be delivered within the scheduled time, directly related to the effectiveness of investment in construction projects in a timely manner to play. How to implement more effective control of the progress of construction projects, so that it successfully reached the intended target, is one of the central tasks of project management. To do this, we must be innovative, continue to draw fresh nutrient trying to adopt a new management thinking, management methods and tools. Standing Beginners, we desire to achieve the ultimate goal of time. How can science and productively manage projects to achieve this goal? This problem is also the starting point of the thesis writing. In order to better grasp the principal contradiction, the more effective implementation of the project management, we also need to find some shortcuts and master, is forthcoming paper focuses on network planning techniques. Network planning technology is a science, it is important to plan management methods. Time management is to develop the core content of the schedule, organize resources to implement the plan, and to take appropriate technical control and coordination. Normally we use the deterministic network planning technology to create network diagrams. WBS defined form an organic whole, to express all the important aspects of the project schedule information. The schedule comparison tools to focus on the implementation of the key work on the critical path dynamic information using banana curve analysis, signals conveyed by the comparative dynamic information, if necessary, be adjusted at any time, to form a feedback mechanism, the completion of the closed-loop control of time management project management efficiency, enhance communication and coordination, and actively promote each target process can make the effect even improve returns. This is this thesis, the combined the project instance you want to show the core content. In this thesis, through the use of the concept of time management principle and calculation methods, under the premise of the meet to create a Work Breakdown Structure WBS chart according to the time schedule of the project and the progress of the planning process, combined with examples of projects, and to develop a total network schedule, draw single arrow network calculated parameters of each six-time to identify the correct key line. Key to the progress of the work will directly affect the duration of the network plan, clear key, you can achieve a clear project time management, focus on the purpose of the work progress control. More important is using it further banana curve analysis, comparison, analysis of two important deviation of the actual progress curve and S-curve to predict the progress of the trend, so the timely adoption of an effective remedial program to control the actual distortion part of the development of the progress curve (the fact that just turn proved the correctness and feasibility of my design chart), and ultimately promote the project to be completed in six days in advance goals.
