ABSTRACT
This chapter provides an overview of how project scheduling tools have evolved over time and discusses how researchers have applied these tools. It also provides the underlying principles of various scheduling methodologies and contextualizes what these tools are, what motivated the development of different tools, and how these tools overcome constraints in project scheduling. The chapter describes the future evolution of project scheduling tools, where the authors believe the forthcoming works are going. It traces the development of scheduling tools and attempts to provide a broadly comprehensive catalogue of various scheduling approaches. Visualization tools for scheduling can trace their origins to the 14th century. A dominant scheduling objective is the minimization of the project completion time. The inclusion of resource availability costs and resource-leveling problems into the method are some examples. Maximizing the quality of a project and its outcomes is the primary objective for many projects.
