In this paper we consider a single machine scheduling problem with deteriorating jobs. By deteriorating jobs, we mean that the processing time of a job is a simple linear function of its execution starting time. For the jobs with chain precedence constraints, we prove that the weighted sum of squared completion times minimization problem with strong chains and weak chains can be solved in polyn...

Using panel data from the National Employment, Unemployment and Underemployment Survey (ENEMDU) for Ecuador, we analyze outcomes of life job satisfaction whether moving bad to a good job—and vice versa—on satisfaction. In contrast with jobs, jobs are characterized by being employed in formal sector, social security registration, earning at least minimum wage. conditional logit estimate, found t...

â â â â â korea’s youth unemployment problem has continued to worsen since 2004. according to an e24, j64, an analysis of raw data from statistics korea’s economically active population survey and supplementary results of the economically active population survey on youths to confirm whether youth unemployment affects all youths, more youths were delaying graduation or taking leaves of abse...

We consider the problem of task assignment in a distributed server system, where short jobs are separated from long jobs, but short jobs may be run in the long job partition if it is idle (cycle stealing). Jobs are assumed to be nonpreemptible, where short and long jobs have generallydistributed service requirements, and arrivals are Poisson. We consider two variants of this problem: a central ...

A novel framework, called JoBS (Joint Buffer Management and Scheduling), is presented for reason-ing about relative and absolute per-class service differentiation in a packet network without informationon traffic arrivals. JoBS has two unique capabilities: (1) JoBS makes scheduling and buffer managementdecisions in a single step, and (2) JoBS supports both relative and absolute ...

A novel algorithm, called JoBS (Joint Buffer Management and Scheduling), is presented for loss and delay differentiation of traffic classes in a packet network. JoBS has two unique capabilities: (1) JoBS makes scheduling and buffer management decisions in a single step, and (2) JoBS supports both relative and absolute QoS requirements of classes. The JoBS algorithm is presented in terms of the ...

The relationship between environmental protection (EP), the economy, and jobs has been an issue of harsh contention for decades. Does EP harm the economy and destroy jobs or facilitate economic growth and create jobs? We address this issue by summarizing the results of the Jobs and the Environment Initiative, research funded by nonprofit foundations to quantify the relationship between EP, the ...

In this paper we study the classical M/G/1 processor-sharing queue under the assumption that there tend to be some jobs much longer than others, as occurs with a heavy-tailed service-requirement distribution. We suggest analyzing the evolution of the long and short jobs in di erent time scales. To study the short jobs in a short time scale, we act as if a speci ed number of long jobs are perman...
