OBJECTIVE To evaluate job participation, career-related problems, and actual job problems in adults with complex congenital heart disease (CHD) compared with adults with mild CHD and reference groups. DESIGN Cross-sectional study. SETTING Patients were randomly selected from the archives of the Department of Pediatric Cardiology, Leiden University Medical Center, Leiden, the Netherlands. ...

scheduling for job shop is very important in both fields of production management and combinatorial op-timization. however, it is quite difficult to achieve an optimal solution to this problem with traditional opti-mization approaches owing to the high computational complexity. the combination of several optimization criteria induces additional complexity and new problems. in this paper, we pro...

AIM The present study aimed to examine the effect of nature of job (High risk/low risk) on psychiatric problems of 200 workers of Tata Motors Ltd. in Jamshedpur. The workers/participants were divided on the basis of the nature of their job (high/low risk) and their salary (high/low paid) resulting in four sub-groups with 50 participants respectively s. METHODS The Middlesex Hospital Questionn...

introduction: man confronts crisis and problems during his life and sometimes because of several pressures commits suicide to escape and save himself. suicide occurs in all classes of the society. some of the demographic and social variables affecting suicide attempt are: age, sex, marital status, job, economic problems, communication and emotional problems, mental disorders and physical illnes...

Bio-Inspired computing is the subset of Nature-Inspired computing. Job Shop Scheduling Problem is categorized under popular scheduling problems. In this research work, Bacterial Foraging Optimization was hybridized with Ant Colony Optimization and a new technique Hybrid Bacterial Foraging Optimization for solving Job Shop Scheduling Problem was proposed. The optimal solutions obtained by propos...

In previous work we introduced a simple constraint model that combined generic AI strategies and techniques (weighted degree heuristic, geometric restarts, nogood learning from restarts) with naive propagation for job shop and open shop scheduling problems. Here, we extend our model to handle two variants of the job shop scheduling problem: job shop problems with setup times; and job shop probl...

Hall, Leung & Li have recently proposed a new model for human multitasking behavior. In their model, a primary job gets interruptions from all waiting jobs whenever it is being processed. Every time an interruption has been received, the worker switches from the primary job to the interrupting job. After part of the interrupting job has complete, the worker switches back to the primary job. Her...

We discuss the application of economic coordination mechanisms to scheduling problems in manufacturing and logistics. We use job shop scheduling as a sample problem domain. We study economically augmented job shop problems (EJSP) which comprise valuation information. We demonstrate how instances of EJSP can be mapped to combinatorial job shop auction problems (CJSAP). A discussion of the tracta...
