Today, planning and scheduling problems are the most significant issues in world make a great impact on improving organizational productivity serving systems such as medical healthcare providers. Since operating room is major problem organizations, optimization of staff equipment plays an essential role. Thus, this study presents multi-objective mathematical model with new categorization (preop...

Operating rooms (ORs) are one of the most expensive and profitable resources within a hospital system. OR managers strive to utilize these resources in the best possible manner. Traditionally, surgery durations are estimated using a moving average adjusted by the scheduler (adjusted system prediction or ASP). Other methods based on distributions, regression and data mining have also been propos...

The scheduling of individual surgical patients has received extensive treatment in the literature, but this paper is the first to propose a model that simultaneously captures the roles of block schedules, block release dates, and request queue policies in the dynamic evolution of the schedule for a single day in an operating room suite. The model is formulated as a stochastic dynamic program an...

Allocation scheduling for daily surgical cases is a decision-making process tasked to anesthesiologists and nurse managers in the operating room (OR). This manuscript focuses on three major areas: the classification and principles of allocation scheduling on workdays in China, flexible strategies of operational decision-making given differences in planned versus actual OR allocations, and perio...

This paper investigates the impact of allowing patient recovery in the operating room when no recovery bed is available. Three types of identical resources are considered : transporters, operating rooms and recovery beds. A fixed number of patients must be planned over a term horizon, usually one or two weeks. The surgery process is modelled as follows : each patient is transported from the war...

Operation rooms are significant cost drivers in hospitals. This is because of the expensive resources that are directly involved in surgery, and the indirect impact that operating room activities have on related activities and resources throughout the hospital. Surgery planning on different levels and time scales are thus central planning problems with strong interactions with other planning pr...
