PlanningLines are glyphs to represent complex, indeterminate planning tasks and their hierarchical structure in a simple and intuitive manner.
The glyph consists of two encapsulated bars, representing minimum and maximum duration, that are bounded by two caps that represent start and end intervals.
Temporal Attributes
For reflecting temporal uncertainties, begin, end, and duration of activities are modeled as intervals including a set of six attributes:
- start interval
- earliest starting time [EST]
- latest starting time [LST]
- end interval
- earliest finishing time [EFT]
- latest finishing time [LFT]
- duration
- minimum duration [minDu]
- maximum duration [maxDu]
Mental Model
In order to facilitate a straight forward explanation, a simple mental model is used. The two black caps representing begin and end interval are mounted at the time scale. These caps are holding two encapsulated bars that represent minimum and maximum duration. Furthermore, the bars can be shifted within the constraints of the two mounted caps.
