Abstract: Under the situation of the shortage of health care staffs and increasing surgeries demand, how to reasonable arrange surgeries and allocate resources so as to solve the operating room resource load imbalance phenomenon in practical operation becomes the most difficult and essential problem in operating room management. The surgery scheduling and nurses rostering, as the core of the management of operating room decision problem, have a different time domain, and will influence each other. Considering several hard and soft  constraints, i.e. the specialty and operating room nurses preference, a medium-term integrated decision-making model integrating surgeries scheduling and operating room nurse rostering has been built. A double nested path structure of ant colony algorithm is designed. The 10-days actual hospital operation data is used for the algorithm comparison analysis and evaluation. It is proved both the feasibility and effectiveness of proposed algorithm for the integrated decision-making problem.
