This paper deals with an optimization problem, which arises when a new transfer line has to be designed subject limited number of available machines, cycle time constraint, and precedence relations between necessary production tasks. The studied problem consists in assigning given set tasks blocks then machines so as find the most robust configuration under task processing uncertainty. robustne...

The present study aims to investigate the relative effectiveness of different types of pragmatic instruction including two collaborative translation tasks and two structured input tasks with and without explicit pragmatic instruction on the production of apologetic utterances by low-intermediate EFL learners. One hundred and fifty university students in four experimental groups and one control ...

Background: Due to the unpredictable nature of disasters, it is crucial to anticipate, define and divide tasks as preparedness activities to respond efficiently. This is because the organizations involved in, becoming aware of their own tasks and other organizations’ tasks. The aim of this study was to explore discrepancies in the viewpoints of members of Kerman University of medical sciences a...

A cyclic production system manufactures a set of products at a constant frequency. Each resource repeatedly performs a certain set of tasks, and the system produces a certain set of units each cycle. The production schedule defines the timing of the tasks within each cycle, which determines system performance on measures such as throughput and work-in-process inventory. This paper describes the...
