In mobile crowdsourcing, mobile users accomplish outsourced human intelligence tasks. Mobile crowdsourcing requires an appropriate task assignment strategy, since different workers may have different performance in terms of acceptance rate and quality. Task assignment is challenging, since a worker’s performance (i) may fluctuate, depending on both the worker’s current context and the task cont...

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...

Task assignment is a central component in crowdsourcing. Organizational studies have shown that worker motivation in completing tasks has a direct impact on the quality of individual contributions. In this work, we examine motivationaware task assignment in the presence of a set of workers. We propose to model motivation as a balance between task relevance and task diversity and argue that an a...

This paper addresses a multi-objective mathematical model for the mixed-model two-sided assembly line balancing and worker assignment with different skills. In this problem, the operation time of each task is dependent on the skill of the worker. The following objective functions are considered in the mathematical model: (1) minimizing the number of mated-stations (2), minimizing the number of ...

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 ...

We investigate the problem of large-scale mobile crowdtasking, where a large pool of citizen crowd-workers are used to perform a variety of location-specific urban logistics tasks. Current approaches to such mobile crowd-tasking are very decentralized: a crowd-tasking platform usually provides each worker a set of available tasks close to the worker’s current location; each worker then independ...

Decision-making is a complex problem in all fields of production, because decision makers have to find the most suitable solution alternative among numerous, while limited by multiple, usually conflicting constraints. In Industry 4.0 era, one widely used production lines are U-shaped lines, which focus on elimination waste through high utilization workers. It means, that worker-machine assignme...

In this paper a new problem called Assembly Line Worker Assignment and Balancing Problem (ALWABP) is introduced. This problem arises in those assembly lines where we have certain limited resources available (normally workers) in which the operation time for every task is different depending on who executes the task, and where there are also some task-worker incompatibilities defined. The proble...
