A stochastic shortest-path MDP model with dead ends for operating rooms planning

Operating room planning and scheduling for outpatients and inpatients: A review and future research

“…Out of the reviewed papers, about 66% incorporate some sort of variability and the surgery duration uncertainty is most frequently taken into account in both settings. [4, 5, 7, 9, 11, 12, 14, 16, 19, 24, 28, 35, 40, 42, 47, 48, 51, 78, 87, 89, 98, 99, 102, 107, 111, 123, 126-128, 135, 142-144, 152, 156, 159, 164, 166, 171, 172, 181, 186, 187, 189, 191, 193, 199, 200] [ 4, 5, 12, 16, 19, 24, 29, 35, 44, 45, 47, 58, 65, 72, 78, 79, 87, 94, 111, 115, 123, 126-128, 135, 138, 143, 144, 152, 156, 189, 191, 195, 200, 210] Demand 33% (51/30) [2, 13, 15, 21, 22, 25-27, 30, 36, 38, 43, 50, 52, 53, 63, 68, 70, 74, 80, 86, 88, 101, 103, 105, 106, 109, 117-121, 130, 134, 147, 148, 154, 161, 162, 169, 177, 179, 183, 185, 188, 190, 192, 201-203, 212] [ 15,22,33,34,36,38,39,43,50,63,68,70,86,103,109,117,119,120,149,151,161,169,170,177,185,190,192,196,201,202] Duration 54% (79/54) [3, 6, 8, 13, 15, 18, 20, 22, 23, 26, 27, 30, 36, 38, 41, 43, 49, 53, 55, 63, 68, 69, 74, 80, 86, 88, 90, 100, 101, 105, 106, 109, 112-114, 117, 119-122, 124,...…”

Operating Room (Re)Scheduling with Bed Management via ASP

“…Other relevant approaches are: Abedini et al 2016, that developed a bin packing model with a multistep approach and a priority-type-duration rule; Molina-Pariente et al 2015, that tackled the problem of assigning an intervention date and an OR to a set of surgeries on the waiting list, minimizing the access time for patients with diverse clinical priority values; and Zhang et al 2017, that addressed the problem of OR planning with different demands from both elective patients and nonelective ones, with priorities in accordance with urgency levels and waiting times. However, bed management is not considered in these three last mentioned approaches.…”
