Process-based simulation models using BPMN for construction management at runtime

In this paper, we present a platform to develop smart and flexible simulation models, based on the notation known as Business Process Modelling Notation, in support of construction management. They are generated in a way that supports effective re-planning at runtime. They merge information about the product model, construction processes and associated resources. Thanks to the notation used, that information can be properly re-arranged in order to generate the work plan even automatically, e.g. by means of search algorithms. At runtime, the business process models are used to monitor work progress and re-instantiate search algorithms for rapid update of work plans. This notation facilitates construction managers who develop work plans taking into account the usage of resources and of the intrinsic dynamics of construction projects. Finally, the application in the energy retrofit of a residential building is showcased.
