Abstract: Motivated by the practices in hospital operations, we study the problem of joint interday planning and intraday scheduling of operating rooms with eligibility constraints and surgery time windows. In this problem, we consider both assigning available surgeries into specific days and scheduling the surgeries on their assigned days, with the eligibility constraints on the operating rooms for the surgeries and the surgery time window requirements, to minimize the total costs of opening operating rooms and overtime of opened operating rooms. From the general problem, we identify several special cases with a fixed number of surgery types and develop polynomial time solution algorithms. For the general problems with arbitrary surgery types, we propose an exact branch-and-price algorithm for the problem where the surgery time windows on each day are agreeable, and an efficient column-generation-based heuristic for the problem where the surgery time windows on each day are non-agreeable. We also conduct extensive computational experiments to show the efficiency and effectiveness of our proposed optimization algorithms.
