This operation diagnostic method of circulating fluidized bed boiler involves: an inferred data calculation step (S4) for inferring the degree of influence ex­ erted by the setting items on the index items, and inferring the target values of the setting items for satisfying the target values of the index items; an ordering step (S5a) for order­ ing the setting items on the basis of the degree of influence exerted by the setting items on the index items; and an out­ put step (S6) for outputting information for controlling the index items to the target values. In the inferred data calcula­ tion step (S4), the target values of the index items are input­ ted into the Bayesian network to calculate probability values which are the degree of influence exerted by the setting items on the index items. In the ordering step (S5a), the probability values are used to order the setting items.
