A heuristic approach for tow-machine no-wait flowshop scheduling with due dates and class setups
This paper studies the two-machine flowshop scheduling problem with class setups in a no-wait processing environment to minimize the maximum lateness. The jobs are divided into job classes and a setup is required at the initial processing of a job or between the processing of jobs of different classes. In a no-wait environment, a job must be processed from start to finish without interruptions ...
متن کاملAssembly and Channel Opening in a Bacterial Drug Efflux Machine
Drugs and certain proteins are transported across the membranes of Gram-negative bacteria by energy-activated pumps. The outer membrane component of these pumps is a channel that opens from a sealed resting state during the transport process. We describe two crystal structures of the Escherichia coli outer membrane protein TolC in its partially open state. Opening is accompanied by the exposure...
متن کاملPinwheel Scheduling With Tow Distinct Numbers
Holte, R., L. Rosier, I. Tulchinsky and D. Varvel, Pinwheel scheduling with two distinct numbers, Theoretical Computer Science 100 (1992) 1055135. “The Pinwheel” is a real-time scheduling problem based on a problem in scheduling satellite ground stations but which also addresses scheduling preventive maintenance. Given a multiset of positive integers A = {aI, a,, _.., a,}, a schedule S for A is...
متن کاملRound - Robin Queueing System with Tow Input - Sources
This paper investigates the reund-robin queueing system with two distinet inputsources. Two types of jobs arrive at the system in Poisson laws with parameters it and R2, respectively. Jobs' service times are subject to the exponential distributions with different means characterized th3 two types of jobs. With the round-robin discipline, the service facility pro:esses each type of job for a max...
متن کاملA Meshfree Solution of Tow-Dimensional Potential Flow Problems
In this paper, mesh-free element free Galerkin (EFG) method is extended to solve two-dimensional potential flow problems. Two ideal fluid flow problems (i.e. flow over a rigid cylinder and flow over a sphere) have been formulated using variational approach. Penalty and Lagrange multiplier techniques have been utilized for the enforcement of essential boundary conditions. Four point Gauss quadra...
