Environmentally Conscious Design

Environmentally conscious consumers and environmental protection legislation have been driving manufacturers to design, produce, and dispose products in a more environmentally responsible manner. One of the key issues is how to position environmentally conscious products in the marketplace. Environmentally conscious design eventually needs to make the transition into mainstream design, rather than stay in a high-profile niche application. The assumption that all consumers have the same preferences does not hold in the real marketplace. Heterogeneous customer preferences require analysis of customer choice behavior at the individual level. In addition, individual customer preferences can be clustered into aggregate preferences of different market segments that are latent within the customer base. In this paper, a Hierarchical Bayesian method is presented to integrate individual level preference information, which can be used to help manufacturers measure product attribute weights and identify appropriate market segments in which customers value the environmentally conscious design the most. An automobile design case study is used to demonstrate the proposed approach.

Airborne Lidar Data

Conventional ground survey data are very accurate, but expensive. Airborne lidar data can reduce the costs and effort required to conduct large-scale forest surveys. It is critical to improve biomass estimation and evaluate carbon stock when we use lidar data. Bayesian methods integrate prior information about unknown parameters, reduce the parameter estimation uncertainty, and improve model performance. This study focused on predicting the independent tree aboveground biomass (AGB) with a hierarchical Bayesian model using airborne LIDAR data and comparing the hierarchical Bayesian model with classical methods (nonlinear mixed effect model, NLME). Firstly, we chose the best diameter at breast height (DBH) model from several widely used models through a hierarchical Bayesian method. Secondly, we used the DBH predictions together with the tree height (LH) and canopy projection area (CPA) derived by airborne lidar as independent variables to develop the AGB model through a hierarchical Bayesian method with parameter priors from the NLME method. We then compared the hierarchical Bayesian method with the NLME method. The results showed that the two methods performed similarly when pooling the data, while for small sample sizes, the Bayesian method was much better than the classical method. The results of this study imply that the Bayesian method has the potential to improve the estimations of both DBH and AGB using LIDAR data, which reduces costs compared with conventional measurements.
