Abstract
As stated at the end of Chap. 4, the complexity of proceduralized tasks should be quantifiable by the concept of graph entropies if we construct a series of graphs representing the features of five kinds of complexity factors. In some respect, this requirement seems to be easily fulfilled because, for example, an ACG is directly comparable to the control flow graph of software. This implies that the effects of two kinds of complexity factors on the complexity of proceduralized tasks might be quantified from the ACG. That is, the first-order entropy of the ACG represents the contribution of logical entanglement on the complexity of proceduralized tasks, while the second-order entropy represents the contribution from the number of actions to be conducted by qualified operators. Unfortunately, we still need three more graphs that are able to characterize the remaining complexity factors: (1) the amount of information to be processed by qualified operators, (2) the amount of domain knowledge, and (3) the level of engineering decision.
