The objective of this work is to demonstrate the potential time and labor savings that may result from increased use of combination vaccinations. The study (GSK study identifier: HO-12-4735) was a model developed to evaluate the efficiency of the pediatric vaccine schedule, using time and motion studies. The model considered vaccination time and the associated labor costs, but vaccination acqui...

Scheduling has become an attractive area for artificial intelligence researchers. On other hand, in today's real-world manufacturing systems, the importance of an efficient maintenance schedule program cannot be ignored because it plays an important role in the success of manufacturing facilities. A maintenance program may be considered as the heath care of manufacturing machines and equipments...

BACKGROUND Increasing the number of vaccine doses may potentially improve overall efficacy. Decision-makers need information about choosing the most efficient dose schedule to maximise the total health gain of a population when operating under a constrained budget. The objective of this study is to identify the most efficient vaccine dosing schedule within a fixed vaccination budget from a heal...

Simultaneous production planning and scheduling has been identified as one of the most important factors that affect the efficient implementation of planning and scheduling operations for the production systems. In this paper, simultaneous production planning and scheduling is applied in a hybrid flow shop environment, which has numerous applications in real industrial settings. In this problem...

Optimizing the energy consumption in wireless sensor networks has recently become the most important performance objective. We assume the sensor network model in which sensors can interchange idle and active modes. Given monitoring regions, battery life and energy consumption rate for each of n sensors, we formulate the problem of maximizing sensor network lifetime, i.e., time during which the ...

The popularity of simulated annealing comes from its ability to find close to optimal solutions for NP-hard combinatorial optimization problems. Unfortunately, current implementations of the method usually require massive computation time. This paper presents a general annealing schedule which speeds up simulated annealing significantly when compared with general schedules available in the lite...

This letter proposes a differential fault analysis on the AES key schedule and shows how an entire 128-bit AES key can be retrieved. In the workshop at FDTC 2007, we presented the DFA mechanism on the AES key schedule and proposed general attack rules. Using our proposed rules, we showed an efficient attack that can retrieve 80 bits of the 128-bit key. Recently, we have found a new attack that ...

Airline schedule development continues to remain one of the most challenging planning activity for any airline. An airline schedule comprises of a list of flights and specifies the origin, destination, scheduled departure, and arrival time of each flight in the airline’s network. A critical component of the schedule development activity is the choice of flight block-times, which depend on sever...
