“…Park et al noted that the significant correlation between complexity and operation times and errors is the leading basis of judging the effectiveness of complexity evaluation method. If the significant correlation exists and the operation time and error increase with the enhancement of complexity level, then the complexity evaluation method will be regarded as valid and it can be used to predict the operation time and error rate [11,12] . The results of Table 1 and Table 2 show that the variation of operation time and error with the enhancement of complexity level is in accordance with the theory Park presented.…”

To investigate how the spaceflight operation complexity and training affect operation errors of spaceflight tasks, a two-factor experiment was designed and conducted. Nine participants performed eighteen spacecraft operation units which were divided into three complexity levels during two training stages. Based on the experiment data, the changes of average operation times and errors at the initial and final stages were analyzed; the equations of linear regression between the complexity and the average operation errors were established. The results showed that the average operation errors were significantly raised with the complexity at the initial stage (P=0.03, 0.02). The operation errors of the low and middle complexity levels at the final stage were much less than those at the initial stage (P<0.05).The operation errors were significantly correlated to the complexity levels at the two stages. It implies that suitable operation complexity and sufficient training are two of the effective ways to ensure the reliability of astronaut operations during spaceflight.

“…Park & Jung [7] developed a measure of procedure complexity called "step complexity" (SC), and later identified, in a nuclear plant setting, that non-compliance was most common when the SC of a procedure was intermediate [10]. (This approach has been criticized, indirectly, as being overly focused on measures of randomness [11].)…”

A framework has been developed that is focused on providing guidance for the design of procedures and checklists. The framework identifies characteristics of the procedure and environment that could influence procedure following behavior, and formal definitions of those factors are introduced. In addition, tradeoffs between the factors that can be controlled by procedure designers are described. This framework, along with the formal definitions, should help enable provide more concrete guidance for researchers and practitioners concerning the design of procedures for human-machine systems.

“…In Park's study, the step complexity measure has been proven in evaluating the complexity of emergence operation procedure in nuclear plants (Park et al, 2001b(Park et al, , 2002. Because training data may contain the effects of various uncontrolled factors, in this study, the proposed complexity measure was validated by a one-factor experiment.…”
