There are two general approaches for scheduling tasks in real-time systems: runtime and pre-runtime scheduling. However, there are several situations where the runtime approach does not find a feasible schedule even if such a schedule exists. The proposed approach uses state space exploration for finding a preruntime scheduling. The main problem with such methods is the space size, which can gr...

It is necessary to compute the execution time upper bound of embedded hard real-time program under the worst condition in embedded system design, which decides how hardware and software to partition and how to schedule process. Modern microprocessors which use cache memory system and instruction pre-fetching increase the difficulty to compute the upper bound accurately. A new estimation method ...

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...

The Measles Control Campaign, which is in progress, will offer measles-mumps-rubella (MMR) vaccination to all primary school children in Australia. In addition, MMR vaccination will be promoted for pre-school and secondary school children who are not already up to date with the Standard Vaccination Schedule. During the Campaign, some children will simultaneously require or will have recently re...

PURPOSE To trace a profile of scientific publications, phase I, in order to know whether or not they show pre-clinical phase data, emphasizing bioethical aspects. METHODS Sixty-one scientific articles, published in 2007, involving research in human beings using new drugs, medicines and vaccines during phase I were analysed. A schedule for data collection was elaborated in which it would be po...

In the Division of Anatomical Pathology of a teaching hospital at the beginning of each month, clinical managers assign expected daily pathology requests to the pathologists on duty. Since the number of these requests is usually large and a division employs a number of pathologists with different sub-specialties, the size of the problem is significant and finding a feasible assignment schedule ...

We present a new algorithm for wavelength division multiplexing (WDM) star optical networks. The resulting protocol is pre-transmission coordination-based without packet collisions. The proposed algorithm tries to schedule the transmission requests of the network, with the assistant of a prediction mechanism. With the prediction of the packet requests the algorithm manages to decrease the calcu...

This study considers the problem of determining operation and maintenance schedules for a containership equipped with components during its sailing according to a pre-determined navigation schedule. The operation schedule, which specifies work time of each component, determines the due-date of each maintenance activity, and the maintenance schedule specifies the actual start time of each mainte...

background: despite the effective pre- and post-exposure treatments, at least 60,000 deaths from rabies occur worldwide every year. post-exposure treatment is considered as one of the most significant measures for preventing human deaths in exposed individuals. the 2-1-1 rabies post-exposure treatment schedule known as zagreb regimen is an abbreviated immunization plan in which a tissue culture...
