Behavior Model of Occupants in Home based on Japanese National Time Use Survey

Yohei YAMAGUCHI, Yoshiyuki Shimoda

Abstract: This paper proposes a new approach for modelling time allocation of occupants in home. In this model, behaviors are divided into routine and non-routine behaviors. Routine behaviors are those undertaken routinely every day like sleeping and working. First, the duration of routine behaviors is determined based on a statistical information on the duration. Then these discrete behaviors are placed on timeline of day by using probability distribution of time allocation. Then, gaps between routine behaviors are filled by non-routine behaviors. For the filling process, two kinds of data are used. The first data is transition probability from a behavior to another behaviors. After a routine behavior is ended, a random number is given to the transition probability to determine the behavior after the routine behavior. Then, by using the second data, statistical data of the duration of non-routine behaviors, the duration of the selected non-routine behavior is determined. This process is repeated until all the gaps are fulfilled. This paper presents the procedure of the model and the method to prepare input data. We evaluate the proposed approach by applying it to generate behavior results of 2000 weekdays for working male and housewife by comparing simulation result with original time use data that are used to generate input data of the model.
