The Diagrammatic And Mathematical Approach Of Project Time Cost Tradeoffs

A potential project management involving time used of a project can always be tradeoff by additional resources input. Such a tradeoff may come from different options of the activity of the project which can be choice. The situation of “Pay more Save Time” is common for project management related decision problems. The available technology of shortening the duration of each activity is often the sources of the time-cost tradeoffs problem. And the problem solving processes always rely upon the techniques of critical path method (CPM) calculation and mathematic programming, for example linear programming, or integer programming etc. The paper includes an introduction to the concepts of CPM method, time-cost tradeoff, and the uses of mathematical programming in spreadsheet. The diagrammatic expression of critical path method and mathematical method will be combined in this paper, by which a more clear and efficient exposition of solving the time-cost tradeoffs problem will be exhibited. As a more efficient tool, the paper discusses such new education pedagogy.
