this study aims to identify job stressors faculty members of birjand university and its relationship with quality of work life. the research method was descriptive and correlational that using cochran's sampling formula that sample size was determined by actual count, 136 members and simple random sampling was used. job stress (hse) questionnaire with reliability (α= 0.90) and quality of w...

we consider online scheduling of jobs with specic release time on m identical machines. each job has a weight and a size; the goal is maximizing total weight of completed jobs. at release time of a job it must immediately be scheduled on a machine or it will be rejected. it is also allowed during execution of a job to preempt it; however, it will be lost and only weight of completed jobs contr...

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. ...

Minimizing the slowdown (expected sojourn time divided by job size) is a key concern of fairness in scheduling and queuing problems where job sizes are very heterogeneous. We look for protocols (service disciplines) capping the worst slowdown a job may face no matter how large (or small) the other jobs are. We call this worst slowdown the liability of the job in question. In the scheduling prob...

This paper deals with a problem of determining lot-sizes of jobs in a real-world job shop-scheduling in the presence of uncertainty. The main issue discussed in this paper is lot-sizing of jobs. A fuzzy rule-based system is developed which determines the size of lots using the following premise variables: size of the job, the static slack of the job, workload on the shop floor, and the priority...

OBJECTIVES The increasing scarcity of donor lungs, especially for small and pediatric recipients has stimulated the development of new operative techniques, which allow larger lungs to be downsized for use in smaller recipients. This approach has only recently gained widespread use-especially for highly urgent recipients-however, it is still not considered a standard procedure. METHODS This r...
