Scheduling of projects under the condition of inflation

This paper develops a linear programming (LP) model for efficient scheduling and management of big projects. The model has an inflation factor as one of its major features and incorporates an extensive modification of existing project scheduling models. The paper includes numerical examples to demonstrate the usefulness of the model and the consequences of excluding inflation factor during project cost-estimation, planning and scheduling in an environment of high inflation. By transforming the variables of the LP model, a new model with fewer constraints is obtained, thereby reducing the amount of effort required to find an optimal solution.
