روش برنامه ریزی هدف گرا مبتنی بر منابع (ORPM) برای ساخت و ساز

This research intends to develop a construction scheduling and planning method, named Object-oriented Resource-based Planning Method (ORPM), for meeting the different requirements at various planning stages. Object-oriented representation is adopted for modelling construction activities. Each object has attribute values to detail the required conditions to construct the activity, such as logical dependency, and resource demands. The planner can define a set of constraints as the active planning constraints based on the planning stage and availability of project information. The planning process checks the active constraints against actual availability of resources for each activity. An activity cannot be scheduled for construction until all of the active constraints are satisfied. At pre-construction stage, less constraints such as technological dependency and resource capacity can be selected into the active planning constraint set; and more constraints can be selected at the construction planning stage when more detailed project information is available. The planning mechanism is demonstrated for various planning purposes through an example project.
