Analysis of a batch-service queue with variable service capacity, correlated customer types and generally distributed class-dependent service times

 Queening models with batch service have been studied frequently, for instance in the domain of telecommunications or manufacturing. Although the batch server’s capacity may be variable in practice, only a few authors have included variable capacity in their models. We analyse a batch server with multiple customer classes and a variable service capacity that depends on both the number of waiting customers and their classes. The service times are generally distributed and class-dependent.he Data center colocation Energy-saving cost can be reduced in the coarse-grained mechanism theory is introduced into our incentive mechanism design to guarantee the feasibility and truthfulness of the two mechanisms.

Approximate computing has seen significant interest as a design philosophy oriented to performance and energy efficiency . Precision tuning is an approximate computing a compiler pass, the parameterized implementations of these trigonometric functions are inserted into the program seamlessly during the precision tuning process.
