In this paper, we develop a model of activity generation for a multi-day planning period that takes within-household interactions between individuals into account. The model is based on the theoretical framework we proposed in earlier work which assumes that utilities of activities are a dynamic function of needs of individuals at person and household levels. In the model, individuals use a utility-of-time threshold parameter to decide when to include an activity in their agenda. The threshold represents a personal perception of time pressure and is continuously adapted based on learning. In an exchange phase, the individuals (re-)allocate household tasks based on a negotiation protocol with the aim of improving the group result. The model takes into account day-varying time-budgets of individuals, influences of perception, selfishness-altruism, joint activity participation and competences of individuals to satisfy particular needs. We illustrate the model by means of simulations and suggest ways for future research.
