APPLICATION OF EVALUATION LINES IN THE ANALYSIS OF TIME-TYPE DATA OF PROJECT PLANS

The Gantt chart is the most commonly used way of displaying a project plan. Its original purpose is to show how the tasks are placed in time and the logical relationships between them. When making the project plan, one problem often arises, that the plan could be hard to comprehend. In case of megaprojects consisting of thousands of activities and even more logical dependencies, it is almost impossible to detect the planning mistakes. The development of the project management software allows the handling of not only the basic parameters of the project but much more data concerning the planning and the tracking as well. In case of hundreds or thousands of activities, the evaluation and presentation of these data is a very timeconsuming task.In this paper, a new method is introduced that has been developed based on the generalization of the progress lines. It is called the system of evaluation lines. With the help of this system, quick and effective evaluation of the project plan is possible. Hundreds of evaluation lines can be defined, which are suitable for the visual display of data concerning activities and costs. These can then be grouped, so that the information related to planning and tracking can be managed separately. In addition, the differences between the plan versions can be pointed out as well. The paper presents that set of evaluation lines that could be used for the analysis of timetype data.
