Agent-based modeling of energy technology adoption: Empirical integration of social,behavioral, economic,and environmental factors

Agent-based modeling (ABM) techniques for studying human-technical systems face two important challenges. First, agent behavioral rules are often ad hoc, making it difficult to assess the implications of these models within the larger theoretical context. Second, the lack of relevant empirical data precludes many models from being appropriately initialized and validated, limiting the value of such models for exploring emergent properties or for policy evaluation. To address these issues, in this paper we present a theoretically-based and empirically-driven agent-based model of technology adoption, with an application to residential solar photovoltaic (PV). Using household-level resolution for demographic, attitudinal, social network, and environmental variables, the integrated ABM framework we develop is applied to real-world data covering 2004–2013 for a residential solar PV program at the city scale. Two applications of the model focusing on rebate program design are also presented.

A Trust/Honesty Model with Adaptive Strategy for Multiagent Semi-Competitive Environments

In multiagent semi-competitive environments, competitions and cooperations can both exist. As agents compete with each other, they have incentives to lie. Sometimes, agents can increase their utilities by cooperating with each other, then they have incentives to tell the truth. Therefore, being a receiver, an agent needs to decide whether or not to trust the received message(s). To help agents make this decision, some of the existing models make use of trust or reputation only, which means agents choose to believe (or cooperate with) the trustworthy senders or senders with high reputation. However, a trustworthy agent may only bring little benefit. Another way to make the decision is to use expected utility. However, agents who only believe messages with high expected utilities can be cheated easily. To solve the problems, this paper introduces the Trust Model, which makes use of trust, expected utility, and also agents’ attitudes towards risk to make decisions. On the other hand, being a sender, an agent needs to decide whether or not to be honest. To help agents make this decision, this paper introduces the Honesty Model, which is symmetric to the Trust Model. In addition, we introduce an adaptive strategy to the Trust/Honesty Model, which enables agents to learn from and adapt to the environment. Simulations show that agents with the Adaptive Trust/Honesty Model perform much better than agents which only use trust or expected utility to make the decision
