In this paper we study an assembly line balancing problem that occurs in sheltered worker centers for the disabled, where workers with very different characteristics are present. We are interested in the situation in which complete parallel assembly lines are allowed and name the resulting problem as parallel assembly line worker assignment and balancing problem (PALWABP). This approach enables...

We propose simple heuristics for the assembly line worker assignment and balancing problem. This problem typically occurs in assembly lines in sheltered work centers for the disabled. Different from the classical simple assembly line balancing problem, the task execution times vary according to the assigned worker. We develop a constructive heuristic framework based on task and worker priority ...

Home care, known also as domiciliary care, is part of the community care service that is a responsibility of the local government authorities in the UK as well as many other countries around the world. The aim is to provide the care and support needed to assist people, particularly older people, people with physical or learning disabilities and people who need assistance due to illness to live ...

In this article, we introduce two new variants of the assembly line worker assignment and balancing problem that allow parallelization of and collaboration between heterogeneous workers. These new line balancing approaches introduce an additional level of flexibility in the assignment and planning process, which may be particularly useful in practical situations where the aim is to progressivel...

We explore the problem of assigning heterogeneous tasks to workers with different, unknown skill sets in crowdsourcing markets such as Amazon Mechanical Turk. We first formalize the online task assignment problem, in which a requester has a fixed set of tasks and a budget that specifies how many times he would like each task completed. Workers arrive one at a time (with the same worker potentia...

Assignment of worker appears as a new problem in the literature for assembly lines (AL) where workforce is heterogeneously located. The difference this line balancing from traditional that task times workers to be assigned stations differ each other. Especially such assignment and balancing, are generally labor-intensive type production. Therefore, while kind lines, it should done considering l...

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...
