ABSTRACT
In a production environment, computerized tasks can be extremely complex. They include physical components, when an operator interacts with equipment and material tools. This chapter demonstrates the principles of utilizing analytical procedures for analysis, description, and further improvement of such complex tasks. The structure of the task can be presented via multiple versions of the same task which have a complex logical organization that includes numerous decision-makings that occur with different probability. The three versions of the task occur with different probabilities in the work process, and together comprise the overall unitary task activity. Version 1 of the task is performed when the item quantity is not equal to the ordered quantity and the difference according to the rules cannot be accepted. Version 2 of the task occurs when the item quantity can be accepted but the item price cannot. Version 3 of the task is performed when both item quantity and price are acceptable and the item is received.
