Coordinating a large program such as building a new skyscraper is a challenging problem reliant for success on planning, scheduling and controlling of project activities by all parties involved in the program. Traditional methods like Gantt charts, Critical Path Method (CPM), and the Program Evaluation and Review Technique (PERT) have significant limitations in the case of large projects which need to be managed concurrently by multiple distributed parties. In the presented paper, a general-purpose reconciliation method is considered and applied to the collaborative project scheduling problem. The main focus is placed on timing constraints specific to the scheduling problem and on systematic ways to detect and to resolve timing conflicts in concurrently developed project schedules. The advantages achieved are mathematically strong guarantees of consistency of the schedules, a capability to manage them concurrently as well as the avoidance of combinatorial explosion peculiar to many other approaches.
