task-based instruction, consciousness-raising and iranian efl learners acquisition and use of collocation

the present study sought to examine whether a task-based approach could have an impact on raising awareness of collocations. moreover, it sought to investigate the facilitative role of consciousness-raising tasks of collocations in the communicative instances of use. to this end, 68 intermediate learners of english were selected via a placement test. the participants were taught with classroom ...

Grammar-Based Integer Programming Models for Multi-Activity Shift Scheduling

This paper presents a new implicit formulation for shift scheduling problems, using context-free grammars to model regulation in the composition of shifts. From the grammar, we generate an integer programming (IP) model having a linear programming (LP) relaxation equivalent to that of Dantzig set covering model. When solved by a stateof-the-art IP solver on problem instances with a small number...

preventive maintenance scheduling with integer programming and constraint programming

preventive maintenance scheduling is to perform a series of tasks that prevents or minimizes production breakdowns and improves the reliability. mathematical models have been developed to solve the preventive maintenance scheduling problem. there are several limitations in the prior work in this area of research. craft combinations are assumed to be given. the craft combination problem concerns...
