Product carbon footprint for product life cycle under uncertainty

Product carbon footprint has a profound impact on the sustainable manufacturing. Due to the uncertainty of product information, it is a crucial issue to estimate product carbon footprint for product life cycle. The paper is devoted to the product carbon footprint estimation model based on the unascertained mathematics theory. After the introduction of unascertained mathematics theory, the integration of the estimation data through unascertained number is discussed in detail. After the model of product carbon footprint for product life cycle is proposed, the estimation method of carbon footprint in the product life cycle based on the unascertained number model is discussed in detail. The product carbon footprint of a modular underactuated exoskeleton robot mechanism is given as an example to demonstrate the proposed methodology. (C) 2018 Elsevier Ltd. All rights reserved.
