This article addresses the ubiquitous topic of Quality of Service (QoS) aware connection provisioning in wavelength routed WDM optical networks. The impact of the connection setup time of an optical connection has not been adequately addressed in the open literature. As such, this paper presents a novel approach that uses the optical connection setup time as a service differentiator during conn...
This paper presents an economic production quantity (EPQ) model with a periodic order quantity (POQ) policy, product reliability and periodic demand. The machine reliability has decreased over time; therefore, the rates of perfect and defective products reduce and increase over time, respectively. A fixed percentage of these products are reworked while the rest is wasted. Some equipment in thei...
Today, manufacturers must meet customer demands in a shorter time with the best quality and lowest cost to survive competitive environment. One way achieve this is reduce production costs by eliminating waste activities system. Machine adjustment processes are that do not create value, Single Minute Exchange of Dies (SMED), lean manufacturing tool, has been developed these activities. In paper ...
This paper explores the flexile flow lines where setup times are sequence- dependent. The optimization criterion is the minimization of total weighted completion time. We propose an iterated greedy algorithm (IGA) to tackle the problem. An experimental evaluation is conducted to evaluate the proposed algorithm and, then, the obtained results of IGA are compared against those of some other exist...
background: the objective of this work was developing a simple and stable time-based on-line setup for assessing the potential of mercury (hg) vapor adsorption of the commercial sorbents used in air sampling and control operation followed by cold vapor atomic absorption spectrometry (cvaas). methods: a special designed separation chamber was used where reduction of the injected hg (ii) solution...
background and purpose: this study was designed to investigate of simulation based education in achieves skills proficiency in medical radiation technologist students. methods: the students randomly were divided in two groups, a (n=25) and b (n=22) that received a routine course and simulation based education respectively. the chain of experiments was concerned to evaluate of skills proficiency...
