Portal Crane

With the continuous development of modern industry in our country, the use of cranes is becoming more and more common, but the unsafe incidents of cranes occur from time to time, which makes the risk assessment of cranes more and more important. Crane risk assessment has become an important part of crane risk management. In order to further promote the development of crane risk management, this paper tests the feasibility and effectiveness of this method through the study of fuzzy safety evaluation method and the direct application of this method to the risk assessment of portal crane.

Portal Crane

In recent decades, with the vigorous development of shipping and transportation logistics industry, a large number of portal cranes have been installed in the ports of our country for production, and some of the equipment has approached or even exceeded its designed service life, and there is a great hidden danger of safety in the continued use of the equipment. This paper discusses a safety performance evaluation method of portal crane based on analytic hierarchy process (AHP). Through the determination and measurement of evaluation index, the safety condition of equipment can be obtained. according to the value of equipment safety condition, the safety performance can be classified, and the user and management organization can respond effectively according to the safety performance level of equipment, and the risk caused by long-term service of equipment can be effectively eliminated.

The Impact

Risk assessment in large organizations with extensive operational domains has been a challenging issue. Employing an efficient method along with realistic pair comparisons, applying subjective inferences of organization experts, and purging the intrinsic ambiguity of inferences, are not reflected in current airlines' safety management. Traditional two-dimensional risk assessment for risk management of safety hazards, however, is no longer sufficient to comply with this complexity. A new model for risk management and a novel formula for risk index calculation, based on a fuzzy approach, are presented in this study. In this new model, unlike in the traditional approach, the latent aftermath of safety reports, especially those which affect the continuity of the business, is also taken into account. In this model, along with the definition of a new structure for risk management, risk analysis should be restructured. To that end, a two-dimensional classic risk formula was replaced with three-dimensional (nonlinear) exponential ones, considering “the impact on the business” as a source of risk and hazard. For measuring the safety risk using the Fuzzy hierarchical evaluation method, considering experts' opinions, three criteria in four different operational fields were developed. This method employs a Fuzzy ANP to help quantify judgments, make qualitative judgments in the traditional method, and weigh the priority of elements contributing to risk. Also, it provides a tool for top-level as well as expert level management to monitor safety more precisely, monitor the safety level within their departments or organizations, set quantitative safety goals and provide feedback for improvement as well as find the most critical areas with the least cost. In this study, an airline has been selected as a case study for the risk assessment of reports based on the new model.

Break Even Point

The article examines the essence of the analysis and assessment of the risks of investment projects in the innovative development of the country's economy. One of the most important tasks for investors in the context of the coronavirus crisis is the analysis, assessment and effective management of risks that can affect investment projects before investing. And also, the investor must identify the factors that negatively affect the project and develop measures to reduce their negative impact. Based on the above, it can be said that improving the risk management methodology and evaluating investment projects based on modern and best practices has become one of the urgent tasks. In this article, the author explains the essence of risk management and presents the main stages of risk management developed by foreign and domestic economists, and also expresses her own opinion about the stages of risk management of investment projects in the form of a scheme. The article also presents the content of the methods of risk analysis that are frequently used in practice. In particular, the author shows the essence of methods for assessing investment risks, such as Break-even point, the sensitivity analysis of the project, the method of Scenarios, the method for assessing the sustainability of the project, Expert evaluation method, Analogy method, and others. We can identify two aims of research: 1) to study the stages of investment risk management, developed by foreign and domestic scientists, and, on their basis, to propose the stages of risk management, developed by the author; 2) to study various methods of risk assessment, which are a key part of investment risk management, and develop proposals for their application in Uzbekistan. To achieve the objectives of the study, the following tasks were identified:  explain the content of the economic categories “risk” and “investment risk”;  explain the content of investment risk management;  study of the process (stages) of investment risk management, developed by foreign and domestic economists;  development by the author of the stages of the investment risk management process;  study and outline methods for assessing the risks of investment projects;  development of recommendations on the application of risk assessment methods in Uzbekistan. Subject of research: methods for assessing the risks of investment projects. Information sources for writing the research was books and articles by foreign and domestic economists.

Set Up

In order to analyze the feasibility of barrier safety performance evaluation with computer simulation method, finite-element models of various vehicles and barriers were set up and simulations results are compared to multiple full-scale impact test data. The results indicate that all safety performance index such as vehicle trajectory, structural adequacy, occupant risk and dynamic deformation can be extracted from computer simulation and FEA results are coincident with those of tests with error less than 10%. Computer simulation method is proved to be highly feasible for safety performance evaluation of barriers. The concept that simulation models must be verified through tests is stressed and the suggestion that laws and regulations on professional audit and management of CAE engineers should be completed is brought out.

Facing with a variety of risks in the process of the metro construction, the metro construction needs to carry on the risk management. The risk assessment is the main link of the metro project risk management also the foundation of the decision analysis. This paper introduces the basic concept of the subway risk management, as a case study of Changchun No.1 subway construction risk assessment using the fuzzy AHP and the comprehensive evaluation method. The results show that Changchun subway station work sites exist many risk factors and the risk level difference is big. The major attention should be paid to the geological risks, the environment risks and the construction technical risks, while the environment risks and the construction technical risks are the focus of the risk analysis.
