THE EMERGING CHALLENGE: THE VALIDITY OF COMPUTATIONAL ORGANIZATION MODEL AND METHODOLOGY

The validity of the computational organization model is a necessary condition and also poses a bottleneck in computational organization theory development. Established on the frontline of computational organization theory, this paper provides an overall discussion on the difficulties in validation and validation methodology of the computational organization model. First, different from natural engineering system model, and also exceeding the traditional empirical method, the computational organization model is faced with various subjective and objective difficulties during the validation progress; second, in developing the situational validation methodology based on relationships among problem field, modeling purpose and referents, it is important for the computational organization model that the validation is conducted according to certain degree; third, the establishment of verification, validation and accreditation approach (VV&A), which is different from the natural engineering system, is an irresistible trend for future development of the computational organization model. Model validation should be focused on concept validation, operation validation, and data validation, as well as the principle of iterative validation approach and such validation should be conducted throughout the modeling process; finally, the validation of computational organization model should be the process to enhance people's confidence in the model. From the perspective of review, if the model is able to pass through all the validation tests, it is helpful for a better understanding of the model's ability, limitation and applicability. In this case, research from interdisciplinary experts is required urgently.
