An autonomous ship refers to a that achieves operation in navigation, management, maintenance, cargo transportation and other aspects. Due the uncertainty risks posed by its risk assessment attracts great attention from researchers. By analyzing historical accident statistics, this paper gives comprehensive analysis perspective of “Man-Ship-Environment-Management”. In addition, quantitative eva...

Cloud Computing is diversified with its services exponentially and lured large number of consumers towards the technology indefinitely. It has become a highly challenging problem to satiate user requirements. Most existing system ingest search space or provide inappropriate service; hence, there need for reliable competent service selection/ranking in cloud environment. The proposed work introd...

Material selection is a main purpose in design process and plays an important role in desired performance of the products for diverse engineering applications. In order to solve material selection problem, multi criteria decision making (MCDM) methods can be used as an applicable tool. Bumper beam is one of the most important components of bumper system in absorbing energy. Therefore, selecting...

The hierarchical TOPSIS model used in this article is able to grasp the ambiguity exists in the utilized information and the fuzziness appears in the human judgments and preferences. The use of the hierarchical fuzzy TOPSIS methodology offers a number of benefits: (1) being a systematic model and straight forward one for working on; and (2) capable of capturing human's appraisal of ambiguity wh...

Abstract In order to solve the problems of unreasonable allocation and low efficiency emergency rescue resources in coal mine accidents, it is necessary establish a resource model by using comprehensive weight-approximation ideal solution (TOPSIS method).This paper takes rock burst as an example extending this designed plan. Firstly, calculated weight evaluation index affecting selected AHP met...
