Aiming at proposing a model which can explain and calculate the variation of intellectual productivity caused by various conditions, the authors have conducted a subject experiment and discussed the details of the proposed model by comparing the results of the computer simulation with the experimental results. The proposed model is a based on a 3-state transition model which consists of a working state, a short-term pause and a long-term pause. The transition between the working state and the shortterm pause is simulated term pause is caused by probabilistic functions calculated from a mental fatigue (MF) as a virtual parameter. A subject experiment was conducted where illuminance on the desk and work motivation were controlled to vary their productivity. the internal parameters of the model to explain the probabilistic functions examined by the experimental results, it was found that the subjects tend to take many short-term pauses but few long-term pauses.
