Spatial Resource Costrained Project Scheduling : the allocation and sequencing of activity groups tospatial resources

In this paper, we present a new topic in connection with project scheduling. Since a limited work space can form a restriction to project scheduling problems, an ecient usage of these work spaces (or so-called spatial resources) is required to produce good project schedules. The requirement for the resource units of these spatial resources is in an adjacent manner (we cannot place a product under construction in separate parts of the work space). A spatial resource unit is not required by a single activity, but by a so-called activity group.
