Abstract
Energy Internet represents a critical breakthrough which is regarded as the synthetic product of information communication technologies and energy technologies. It is highly conducive to providing possible solutions for transforming energy management methods, reducing carbon emissions and achieving sustainable development. The extensive attention of scholars has been drawn to the progress of Energy Internet. However, the multi-objective optimisation and multi-criteria decision making (MCDM) for Energy Internet considering uncertainty still has some problems. (1) The actual number of optimisation objectives for Energy Internet design is more than two so that it is difficult to adopt conventional intelligence algorithms to solve it. (2) Most intelligence algorithms for double-objective optimisation model are not desirable. (3) The MCDM process of Energy Internet is not considered systematically. To solve these problems, an integrated approach combining improved great deluge algorithm (GDA), evidence reasoning (ER), interval algorithm, and fuzzy grey correlation analysis for multi-objective optimisation and MCDM of Energy Internet considering uncertainty is proposed in this paper. The practicality and effectiveness of the proposed approach are illustrated by a visual case study of Energy Internet design. (C) 2019 Elsevier B.V. All rights reserved.

Abstract
Hepatobiliopancreatic surgery is challenging becouse of the complexity of resections and reconstructions and variability of vascular anatomy. The arterial vascularization of the liver is susteined by the common hepatic artery (CHA) that originates from the celiac trunk (CT). The CHA bifurcates into the gastroduodenal artery (GDA) and proper hepatic artery (PHA) 0.5-1 cm medial to the common bile duct (CBD), and the PHA bifurcates into a right and a left branch at hepatic hilum. The most frequent variants are the right hepatic artery (RHA) from the superior mesenteric artery (SMA), the left hepatic artery (LHA) from the left gastric artery (LGA) or a combination of these two variants. Herein, we describe the case of a 70 years old woman affected by IPMN of the pancreas with a quadrifurcation of CHA, associated with a RHA off the SMA.
