A recent interesting paper ~Cooper, Niu, and Srinivasan @2# ! shows how for some cyclic production systems reducing setup times can surprisingly increase work in process+ There the authors show how in these situations the introduction of forced idle time can be used to optimize system performance+ Here we show that introducing forced idle time at different points during the production cycle can...

This paper represents linkage network of queues consisting of biserial and parallel servers linked to a common server in series with a flowshop scheduling system consisting of two machines. The significant transportation time of the jobs from one machine to another is also considered. Further, the completion time of jobs/customers (waiting time + service time) in the queue network is the set...

Generally, there are periodic interrupt services in the real-time embedded systems even when the system is in the idle state such as the periodic clock tick interrupts. To minimize the idle power, power management therefore should consider the effect of periodic interrupt services. In this paper, we deal with this problem considering two scenarios. In case the periodic interrupt cannot be disab...

Automated problem solving is viewed typically as the expenditure of computation to solve one or more problems passed to a reasoning system. In response to each problem received, e ort is applied to generate a solution and problem solving ends when the solution is rendered. We discuss the notion of continual computation that addresses a broader conception of problem by considering the ideal use ...

Production environment in modern industries, like integrated circuits manufacturing, fiberglass processing, steelmaking, and ceramic frit, is characterized by zero idle-time between inbound outbound jobs on every machine; this technical requirement improves energy efficiency, hence, has implications for cleaner production other situations. An exhaustive review of literature first conducted to s...

In this paper, we proposed a Power Saving Scheme (PSS) multi-hop sensor network using partition clusters. It avoids collision and idle listening time of sensor nodes for better overall network life time. The basic sensor nodes are simple and have limited power supplies, whereas the cluster head nodes are much more powerful and have many more power supplies, which organize sensors around them in...

One challenging issue of sensor networks is extension of overall network system lifetimes. In periodic data gathering applications, the typical sensor node spends more time in the idle state than active state. Consequently, it is important to decrease power consumption during idle time. In this study, we propose a scheduling scheme based on the history of RTS/CTS exchange during the setup phase...
