A tool-supported framework for work planning on construction sites based on constraint programming

Abstract

This paper presents a framework taking advantage of the capabilities of current constraint solvers to plan the work on construction sites. It combines different constraints under a common framework to facilitate the definition of temporal relations between different tasks and provides a user-friendly web interface, which facilitates the planning of construction sites. Even though the framework uses complex mathematical models, the users do not need to know the underlying theoretical framework. Another important feature of the framework is, in contrast to usual static planning, that solutions can be dynamically adapted to take into account delays happening during the actual construction process. In order to show the applicability of the methodology, the paperspaper shows how a real construction project can be planned by using the framework.
