Job scheduling is an important but difficult task to wafer fabrication factories. To further improve the performance of job scheduling in a wafer fabrication factory, a fuzzy-neural dynamic-bottleneck-detection (DBD) approach is proposed in this study. The fuzzy-neural DBD approach is modified from the traditional DBD approach after incorporating some major changes. First, taking into account t...

This paper examines financial professionals’ overconfidence in their forecasting performance. We are the first to compare individual financial professionals’ self-ratings with their true forecasting performance. Data spans several years at monthly frequency. The forecasters in our sample do not provide feasible self-ratings compared to their true performance but show overconfidence on average. ...

Sociology, computer networking and operations research provide evidence of the importance of fairness in queuing disciplines. Currently, there is no accepted model for characterizing fairness in parallel job scheduling. We introduce two fairness metrics intended for parallel job schedulers, both of which are based on models from sociology, networking, and operations research. The first metric i...

Forms of well-being vary in their activation as well as valence, differing in respect of energy-related arousal in addition to whether they are negative or positive. Those differences suggest the need to refine traditional assumptions that poor person-job fit causes lower well-being. More activated forms of well-being were proposed to be associated with poorer, rather than better, want-actual f...

Multi-File Caching issues arise in applications where a set of jobs are processed and each job requests one or more input files. A given job can only be started if all its input files are preloaded into a disk cache. Examples of applications where Multi-File caching may be required are scientific data mining, bit-sliced indexes, and analysis of sets of vertically partitioned files. The differen...

This paper investigates static job scheduling schemes that distribute workload in a network of computers with different speeds. Static schemes involve very low overhead and complexity compared to dynamic schemes, but can still provide significant performance improvement over the case of no load balancing. Optimization techniques are proposed for workload allocation and job dispatching. Workload...

According to recent research, stable dispositional factors may result in considerable consistency in attitudes such as job satisfaction across time and situations. If true, this finding may have important implications. For example, Staw and Ross (1985) argued that "many situational changes such as job redesign . . . may not affect individuals as intended." Such personnel programs "may be prone ...

Background: Job stress is one of the most important diseases of the century, plays a major role in today's organizations which researchers are trying to control and reduce it. One method for control and reduce of stress is hidden in job and its characteristics. Nursing students are faced continually with one of the stressful job. Hackman & Oldham Job Characteristics Model is famous theory in th...

This paper considers the job scheduling problem in virtual manufacturing cells (VMCs) with the goal of minimizing two objectives namely, makespan and total travelling distance. To solve this problem two algorithms are proposed: traditional non-dominated sorting genetic algorithm (NSGA-II) and knowledge-based non-dominated sorting genetic algorithm (KBNSGA-II). The difference between these algor...

The Distributed and Flexible Job-shop Scheduling problem (DFJS) considers the scheduling of distributed manufacturing environments, where jobs are processed by a system of several Flexible Manufacturing Units (FMUs). Distributed scheduling problems deal with the assignment of jobs to FMUs and with determining the scheduling of each FMU, in terms of assignment of each job operation to one of the...
