An ant colony optimization approach for solving an operating room surgery scheduling problem
Operating room surgery scheduling deals with determining operation start times of surgeries on hand and allocating the required resources to the scheduled surgeries, considering several constraints to ensure a complete surgery flow, the resource availability, and specialties and qualifications of human resources. This task plays a crucial role in providing timely treatments for the patients whi...
متن کاملJobshop scheduling with imprecise durations: a fuzzy approach
|Jobshop scheduling problems are NP ?hard problems. The durations in the reality of manufacturing are often imprecise and the imprecision in data is very critical for the scheduling procedures. Therefore, the fuzzy approach, in the framework of the Dempster-Shafer theory, commands attention. The fuzzy numbers are considered as sets of possible probabilistic distributions. After a review of some...
متن کاملOperating Room Scheduling Considering Patient Priorities and Operating Room Preferences: A Case Study
Operating rooms have become the most important areas in hospitals because of the scarcity and cost of resources. The present study investigates operating room scheduling and rescheduling considering the priority of surgical patients in a specialized hospital. The ultimate purpose of scheduling is to minimize patient waiting time, surgeon idle time between surgeries, and penalties for deviations...
متن کاملSurgery cancellations after entering the operating room
Background Surgery cancellation results in unavailability of the operating room and loss time. We identified the frequency of and reasons for operation cancellations after patients entered the operating room and assessed the preventability of such cancellations. Findings A retrospective chart review of all scheduled surgical procedures proposed under general anesthesia in a period spanning 20...
متن کاملMulti-period and multi-resource operating room scheduling and rescheduling using a rolling horizon approach: a case study
In this paper, a multi-period and multi-resource operating room (OR) scheduling and rescheduling problem with elective and semi-elective (semi-urgent) patients is addressed. A scheduling-rescheduling framework based on the so-called rolling horizon approach is proposed to solve the problem. The core of the proposed framework is a novel proposed mixed-integer linear programming (MILP) model with...
