priority rules

Project scheduling is the act of constructing a timetable for each project activity, and differs in complexity due to the presence of renewable resources with limited availability. The construction of a resource feasible project schedule within the restrictions of a limited availability of renewable resources can be done to optimize a predefined scheduling objective (see “Resource constrained project scheduling: What is my scheduling objective?”). In this article, the differences between three possible schedules that can be constructed from project network data are described, as follows: 

Priority based project scheduling is a quick and easy heuristic scheduling technique that makes use of two components to construct a resource feasible project schedule, a priority rule and a schedule generation scheme (see “Optimizing regular scheduling objectives: Priority rule based scheduling”). In this article, the use and calculations of priority rules will be illustrated on a fictitious project example network. More precisely, the calculations of activity priorities will be based on four sources of information, as follows:

Project scheduling is the act of constructing a timetable for each project activity, respecting the precedence relations and the limited availability of the renewable resources, while optimizing a predefined scheduling objective (see “Resource constrained project scheduling: What is my scheduling objective?”). The presence of resources during project scheduling often leads to a complex scheduling process and hence, simple priority based scheduling rules are used to facilitate this scheduling process.

Priority based project scheduling is a quick and easy heuristic scheduling technique that makes use of two components to construct a resource feasible project schedule, a priority rule and a schedule generation scheme (see “Optimizing regular scheduling objectives: Priority rule based scheduling”). In this article, the use of two alternative schedule generation schemes will be illustrated on a fictitious project example network, as follows:
