Abstract:
The operating theater layout problem (OTLP) in a hospital aims to determine for a set of facilities their positions and orientations on the floor-layout of departments in a hospital subject to a set of constraints on distances, available areas, and non-overlapping facilities according to international medical standards and specifications. The OTLP has two main objectives: A quantitative objective to minimize the interdepartmental travel costs among facilities and a second qualitative objective to maximize the closeness rating among facilities. In this paper, a mixed integer linear programming (MILP) model is proposed for OTLP. The MILP model is validated on two illustrative cases to determine the positions as well as the orientations of facilities in a two-dimensional space for a two-floor hospital using commercial optimization software.
