this paper presents a new mathematical model for the problem of scheduling part families and jobs within each part family in a flow line manufacturing cell where the setup times for each family are sequence dependent and it is desired to minimize the maximum completion time of the last job on the last machine (makespan) while processing parts (jobs) in each family together. gaining an optimal s...

he traditional Chinese acupuncture has been reported to alleviate pain and is widely accepted as a complement therapy for pain relief in the world. In 1996, a novel acupuncture strategy, Fu's subcutaneous needling (FSN), was developed from the traditional Chinese acupuncture, but quite different from it. In FSN, needles are penetrated and swayed in the subcutaneous layer, but not the muscular l...

This paper considers the scheduling problem that minimizes the average response time of two jobs subject to window constraints. By window constraints, we mean that within a fixed time interval, the server can serve at mostW packets from one job, where W is called the window size of the job. This paper investigates the effects of the window constraints in detail, and derives the optimal policy. ...

Job-shop Scheduling Problem (JSP) is one of extremely hard problems because it requires very large combinatorial search space and the precedence constraint between machines. The traditional algorithm used to solve the problem is the branch-andbound method, which takes considerable computing time when the size of problem is large. W e propose a new method for solving JSP using Genetic Algorithm ...

Many commercial job scheduling strategies in multi processing systems tend to minimize waiting times of short jobs. However, long jobs cannot be left aside as their impact on the performance of the system is also determinant. In this work we propose a job scheduling strategy that maximizes resources utilization and improves the overall performance by allowing jobs to adapt to variations in the ...

Recently, power awareness in high performance computing (HPC) community has increased significantly. While CPU power reduction of HPC applications using Dynamic Voltage Frequency Scaling (DVFS) has been explored thoroughly, CPU power management for large scale parallel systems at system level has left unexplored. In this paper we propose a power-aware parallel job scheduler assuming DVFS enable...

abstract aim and background: job burnout is considered as the main factor of decreasing efficiency, losing manpower and making physical and mental complication's specially in human service professions, this survey intends to study job burnout for psychologists and psychiatrists of city of isfahan and it is interrelation with individual and professional factors. methods and materials: this surve...

All three papers deal with important policy issues. Ruhm, whose analysis ranges the most widely, goes furthest in recommending policy activism. Podgursky and Swaim (P&S) are somewhat more re strained, but it is clear that they too favor special assistance for displaced workers. In our own paper we see advantage in workers being given notification of their impending redundancy in the specific co...
