Research on Model of the Shortest Time Path and Transport Cost in Multimodal Transportation

Wei Zhong,Shen Jinsheng,Huang Ailing,Zhang Zhiwen,Shi Dinghuan

Strategic Study of CAE 2006, Volume 8, Issue 8, Pages 61-64

Abstract:

With the rapid development of economy, unimodal transport cannot meet the demand of customers, inTaking into consideration the transport time between node and node, mode-to-mode time and possible transportnode in multimodal transportation networks, the shortest time model of path is presented, and then the transportcost of the path in multimodal transportation network is calculated, providing the theory foundation

Frontiers of Structural and Civil Engineering 2017, Volume 11, Issue 1, Pages 17-26 doi: 10.1007/s11709-016-0369-3

Abstract: This study developed an integrated life-cycle cost analysis (LCCA) model to quantify the impact of pavementpreservation on agency cost and vehicle operation cost (VOC) and analyzed the optimal timing of preservationtraffic loading and the initial IRI value significantly affects life extension and the benefit of agency costThe benefit in VOC is one to two orders greater in magnitude as compared to the benefit in agency costtiming calculated based on VOC is always earlier than the optimal timing calculated based on agency cost

Comparative cost analysis of three different anesthesia methods in gynecological laparoscopic surgery

Xiaohui Chi, Yeling Chen, Mingfeng Liao, Fei Cao, Yuke Tian, Xueren Wang

Frontiers of Medicine 2012, Volume 6, Issue 3, Pages 311-316 doi: 10.1007/s11684-012-0205-7

Abstract:

In the current study, we assessed and evaluated the costs and benefits of three popular methods of general anesthesia practiced in our department for gynecological laparoscopic surgery in recent years. Sixty adult female patients who underwent elective gynecological laparoscopic surgery under general anesthesia were randomly divided into three groups: group V, group I and group C. In group V, anesthesia was induced intravenously with midazolam, remifentanil, propofol and vecuronium, and maintained with continuous infusion of propofol and remifentanil. In group I, anesthesia was intravenously induced with midazolam, fentanyl, propofol and vecuronium, and maintained with inhaled isoflurane and intravenous bonus of fentanyl. In group C, anesthesia was induced as in group I, but maintained with isoflurane inhalation combined with propofol-remifentanil infusion. All patients received vecuronium for muscle relaxation. Perioperative incidences of complications and total anesthesia costs for patients in all groups were recorded. In addition, postoperative satisfaction of the patients was also noted, and similar outcomes of the satisfaction were reported in all 60 patients. Although there was no statistical significance among groups, the incidence of postoperative nausea and vomiting were higher in group C, and the rates of shivering and the needs for analgesics were higher in group V. Anesthesia costs in group I were the lowest. Therefore, it is concluded that the costs of anesthesia induced with midazolam, fentanyl, propofol, vecuronium, and maintained with isoflurane, fentanyl and vecuronium are cheapest, and there is no significant difference in patients’ satisfaction and safety among the three above-mentioned methods of anesthesia in our department.
