A Process of Uncertainty Handling Method to Smart Mobility Application Development

In system development, specification changes are often made to improve or change service. The cause of the specification changes is uncertainty which can not be fixed until the practical use of the system gets started. The handling method of uncertainty has already been proposed, but detailed processes have yet to be defined for developing smart mobility applications. The paper proposes a detailed process for applying the handling method of uncertainty to smart mobility applications, and also propose a method to facilitate to conduct the process employing Model-Driven Development technology. For continued development, we will also refer to how to use operational information to improve requirements and designs, and how to analyze impacts when requirements and design are added or changed. We conducted a case study to demonstrate our proposed method. For the case study, we used parking recommendation application. As a result, two uncertainties were able to be resolved.
