After a disruption in an interconnected set of systems, it is necessary to restore service. This requires the determination of the tasks that need to be undertaken to restore service, and then scheduling those tasks using the available resources. This paper discusses combining mathematical programming and constraint programming into multiple objective restoration planning in order to schedule t...

We solve the Forward Surgical Team (FST) Operating Room (OR) Scheduling Problem for Mass Casualty (MASCAL) events to determine the optimal OR surgical schedule for a single FST given deterministic, sequence-dependent OR setup times as to minimize the total length of the schedule by minimizing the total surgical setup time. We perform a two-part computational experiment to solve the problem of i...

Switched Ethernet has many features for real-time communications but cannot guarantee the timely delivery of a real-time message due to possible collisions on the output ports. This paper first suggests a feasible condition for real-time communication of periodic messages on a master-slave-based synchronized switched Ethernet. Then an EDF (Earliest Deadline First)-based scheduling algorithm tha...

0 Abstract High surgical bed occupancy levels often result in heightened staff stress, frequent surgical cancellations and long surgical wait times. This congestion is in part attributable to surgical scheduling practices which often focus on the efficient use of operating rooms but ignore resulting downstream bed utilization. This paper describes a transparent and portable approach to improve ...

In this paper, we study a real-world problem arising from the operations of a hospital service provider, which we term the master physician scheduling problem. It is a tactical planning problem of assigning physician duties to the defined time slots/shifts over a time horizon incorporating a large number of constraints and complex physician preferences. The goals are to satisfy as many physicia...

In manufacturing systems, generally employee timetabling and job shop scheduling is considered to be too hard and complex. To achieve an integrated manufacturing environment, the integration of employee timetabling and job shop scheduling is essential. It is a process of assigning employees into work slots in a pattern according to the hierarchy level of the employee, job allotment, individual ...

Abstract Defining an optimal schedule for arbitrary algorithms on a network of heterogeneous machines is an NP complete problem. This paper focuses on data parallel deterministic neighborhood computer vision algorithms. This focus enables the polynomial time definition of a schedule which minimizes the distributed execution time by overlapping computation and communication cycles on the network...

Background. Recent data suggest that transcatheter aortic valve replacement (TAVR) for the treatment of severe stenosis (AS) is viable in cancer patients. TAVR may be preferred patients due to its minimally invasive nature and smaller impact on oncologic therapies compared SAVR. Objectives We sought determine if an acceptable alternative SAVR whether allows earlier initiation or resumption anti...

Operating room (OR) planning and scheduling is a popular and challenging subject within the operational research applied to health services research (ORAHS). However, the impact in practice is very limited. The organization and culture of a hospital and the inherent characteristics of its processes impose specific implementation issues that affect the success of planning approaches. Current tac...
