Abstract
Planning and scheduling are two closely related areas that deal with organizing activities to achieve a particular goal (planning) and allocating these activities to limited time and resources for execution (scheduling). However, regarding the tools supporting the planning and scheduling processes, these two areas are still far from each other.
Progress in scheduling has been driven by industry and many techniques and tools to support the scheduling process have been designed. On the other hand, planning is still more an academic topic and, until recently, engineering support of the planning process has been limited.
The focus of planning community was mainly on design of efficient planners, but this started to change in recent years and several tools supporting the planning process have been designed. This chapter focuses on interactive visualization of plans and schedules, that is, on the way how plans and schedules can be presented visually to users, and on tools that can work with these visualizations.
