The mixed work assignment technique was applied to the modular production concept solve apparel assembly line balancing problem. Specifically, an algorithm implemented generate workstations by first classifying tasks into modules through analysis of manufacturing process and assigning grouped in single task–multiple workers multiple tasks–single worker methods. Then, sequentially performed cons...

abstract background: workplace exposures as in clinical work can cause disorders. some organ systems are at risk. this work may be a risk factor for early symptoms of menopause. the objective of this study was to compare the early symptoms of menopause between hospital personnel who work in clinical and office settings. materials and methods: this was a historical cohort study conducted on clin...

This paper employs a game-theoretic framework and comparative historical approach to study an institutional change triggered by an extraordinary shock — the Great Depression. By characterizing “corporate welfarism” practiced by large manufacturing firms in the U.S. and Japan in the 1920s as implicit employment contracts based on internal enforcement, the paper reexamines the impact of the Depre...

This paper develops a mathematical model in dynamic virtual cellular manufacturing systems with the multiperiod cell formation problem, production planning, dynamic virtual system reconfiguration and training workers. Since workers have important role in doing jobs on machines, assignment of workers to cells becomes a crucial factor in cellular manufacturing system. Also we have shown the role ...

The evolutionary success of ants and other social insects is considered to be intrinsically linked to division of labor among workers. The role of the brains of individual ants in generating division of labor, however, is poorly understood, as is the degree to which interspecific variation in worker social phenotypes is underscored by functional neurobiological differentiation. Here we demonstr...

This paper reports on the relationship between dimensions of control (skill discretion and decision authority) and burnout (emotional exhaustion, depersonalization, and reduced personal accomplishment) among 164 human service workers. It examines the diVerential in ̄ uence of job demands, control (skill discretion and decision authority) and social support (supervisor, co-workers, others) on eac...

In this article, we study the design and control of manufacturing cells with a mix of manual and automated equipment, operating under a CONWIP pull protocol, and staffed by a single agile (cross-trained) worker. For a three-station line with one automated station, we fully characterize the structure of the optimal control policy for the worker and show that it is a static priority policy. Using...

Virtual cellular manufacturing systems (VCMS) have come into existence, replacing traditional cellular manufacturing systems (CMS), to meet highly dynamic production conditions in terms of demand, processing times, product mix and processing sequence. While cell formation phase of VCMS has been dealt quite voluminously, worker assignments phase has gained momentum recently after researchers sta...

The article’s purpose is to measure the impact of human resources management skills on accounting information quality in kurdistan public sector. To enable study resource at sectors Kurdistan region Iraq, researchers used five elements, first communication skill, second flexibility third negotiation fourth ethical action and fifth compassion skill. assess current study, a quantitative research ...
