ABSTRACT
Complexity has been studied in various fields of science, including economics, biology, engineering, and so on. Some economists, such as Rosser, apply a transdisciplinary approach when considering complexity. This chapter presents task-complexity evaluation of three versions of the computerized inventory receiving task before and after improvements. These are: the task performance takes less time and effort, the safety of the performance improves, and cognitive effort is reduced. All this makes the task performance much more simple and reliable. The chapter considers the concept of complexity from a psychological perspective and demonstrates that this approach is important for studying the efficiency of human labor and that the analysis of complexity is useful for economics, work psychology, and ergonomics. The presented approach to the quantitative assessment of complexity allows to develop new measures of complexity that reflect the specifics of the task under consideration.
