Abstract

Current dynamic layout models only consider changes in the placement of temporary facilities, like workstations and material storages, without considering changes in the spatial structure of the layout itself. While they are practical to account for repositioning of the facilities and the resulting changing material flows, these models assume a static layout structure over time. To address this limitation, we present a novel optimization model introducing 'dynamic spaces'. They accommodate the changing availability of rooms or areas representing the layout over time. This innovation finds application in many cases, such as optimizing deconstruction projects where parts of a building are taken down and can’t be used as locations anymore midway through the project or when safety protocols require certain areas of a factory to be sealed off temporarily during remodeling. Additionally, it can also be used to represent expanding layouts e.g., if surrounding areas are temporarily used during a construction project. In this contribution we analyze the difference in the optimization process compared to classical formulation and show the strength of the new model in numerical case studies.
