If shortest jobs are served first, splitting a long job into smaller jobs reported under different aliases, will reduce the actual wait until completion. If longest jobs are served first, the dual maneuver of merging several jobs under a single reported identity is profitable. Both manipulations can be avoided if the scheduling order is random, and users care only about the expected wait until ...

We address the problem of scheduling a single batching machine to minimize the maximum lateness with a constraint restricting the batch size. A solution for this NP-hard problem is defined by a selection of jobs for each batch and an ordering of those batches. As an alternative, we choose to represent a solution as a sequence of jobs. This approach is justified by our development of a dynamic p...

This paper considers the problem of minimizing make-span and maximum tardiness simultaneously for scheduling jobs under non-identical job sizes, dynamic job arrivals, incompatible job families,and sequence-dependentfamily setup time on the single batch- processor, where split size of jobs is allowed between batches. At first, a new Mixed Integer Linear Programming (MILP) model is proposed for t...

Job-shop scheduling problems constitute a big challenge in nowadays industrial manufacturing environments. Because of the size of realistic problem instances, applied methods can only afford low computational costs. Furthermore, because of highly dynamic production regimes, adaptability is an absolute must. In state-of-the-art production factories the large-scale problem instances are split int...

BACKGROUND Work design integrates work characteristics having organizational, social and job components which influence employees' welfare and also organizational goals. We investigated the effects of work characteristics and other predictors to job satisfaction, turnover intention, and burnout in doctors of the public primary, public secondary and private facilities of the district health syst...

In this study, meta-analytic procedures were used to examine the relationships between psychological contract perceived breach and certain outcome variables, such as organizational commitment, job satisfaction and organizational citizenship behaviours (OCB). Our review of the literature generated 41 independent samples in which perceived breach was used as a predictor of these personal and orga...

MapReduce has emerged as a successful framework for addressing the heavy demand for large-scale analytical data processing, in this peta-byte age. However, while on one hand the sheer size of data makes problems more challenging, the flexibility offered by the MapReduce frameworks on the other hand, makes the learning curve far steeper than expected. The general idea behind a MapReduce framewor...

In this study we show the comparative study of job satisfaction in Public and Private Bank sectors. This paper will investigate as to what extent job satisfaction has lead to good working performance in formal organization. The study will examine the factors which influence employee’s job satisfaction in organization such as Job involvement, Organizational commitment, Quality of work life, orga...
