Improvement Of Work Process Performance With Task Assignments And Mental Workload Balancing, Cansu Kandemir Oct 2016

Improvement Of Work Process Performance With Task Assignments And Mental Workload Balancing, Cansu Kandemir

Engineering Management & Systems Engineering Theses & Dissertations

The outcome of a work process depends heavily on which tasks assigned to which employees. However, sometimes-optimized assignments based on employees’ qualifications may result in an uneven and ineffective workload distribution among them. Likewise, an even workload distribution without considering the employee's qualifications may cause unproductive employee-task matching that results in low performance of employees. This trade-off is even more noticeable for work processes during critical time junctions, such as in military command centers and emergency rooms that require being fast and effective without making errors.

This study proposes that optimizing task-employee assignments according to their capabilities while also keeping …
