Today's competitive and dynamic environment forces companies to be highly responsive and customer oriented to survive and be successful. Short cycle time operation enables a warehouse manager to be more responsive, flexible and competitive. For example, it more easily handles insertion of late arriving but high priority orders into picking operation. However, to operate in a short cycle environ...

The flexibility present in a job shop is an important determinant of the future success of the shop, since it increases the ability to deal with the changes a job shop is faced with in a dynamic environment. The presence of idle-time in a job shop schedule contributes considerably to this flexibility. By introducing an anticipation factor that preserves idletime in the scheduling process more f...

this paper presents future trends of urban wastes and their impacts on the environment of african cities using plausible mitigation scenarios. to accomplish this, an integrated dynamic model for urban waste flows was developed, tested, calibrated and validated. its parameter sensitivity was analyzed. using population projection up to 2052 with different levels of technological implementation, p...

in this article, we tried to emphasis in how the range of torsionally stiff and flexible single story buildings works. the designed base was according to provisions of the canadian standard, 2005 nbcc. the behavior of nonlinear dynamic time history of eight building models subjected to seven horizontal bi-directional ground motions compatible with design spectra are investigated. these models c...

The run-time characteristics of Java, such as high frequency of method invocation, dynamic dispatching and dynamic loading, make Java more difficult than other object-oriented programming languages, such as C++, for conducting Worst-Case Execution Time (WCET) analysis. To offer a more flexible way to develop object-oriented real-time applications in the realtime Java environment without loss of...

Compared with traditional distributed environment, the net-centric environment brings on more demanding challenges for information sharing with the characteristics of ultra-large scale and strong distribution, dynamic, autonomy, heterogeneity, redundancy. This paper realizes an information sharing model and a series of core services, through which provides an open, flexible and scalable informa...
