Simple Additive Weighting

Recently, risk assessment has become one of the most challenging issues in the areas of construction and public-private partnerships (PPPs). To address risk assessment issues, various decision-making techniques have been proposed, each with its own specific disadvantages and advantages. This paper investigates step-wise weight assessment ratio analysis (SWARA), complex proportional assessment (COPRAS), fuzzy analytic network process (FANP), fuzzy analytic hierarchy process (FAHP), fuzzy technique for order of preference by similarity to ideal solution (FTOPSIS), simple additive weighting (SAW) and evaluation based on distance from average solution (EDAS) in order to define how various multi-attribute decision-making (MADM) methods compare when used for risk assessment in PPP projects. For this study, 5 risk assessment criteria and 10 types of risk used in Iranian highway PPP projects were selected. Four suitability and applicability tests were used to measure agreement between the rankings derived from the MADM methods. Final results show that all techniques had approximately the same rankings of risk assessment, with the SWARA, COPRAS, and EDAS methods performing slightly better. The findings of this study will help the parties in PPP and construction projects to select the best risk assessment method.

A reliability risk assessment model based on fuzzy FMEA was presented by using fuzzy comprehensive evaluation. Fuzzy matrixes were constructed according to the investigation data, in which occurrence probability ranking, effect severity ranking and detection difficulty ranking are all weighted analyzed. A fuzzy hierarchy analysis method was used to obtain the weight of each influence factor. In the model, the potential fault modes and the reasons can be analyzed and the preventive measures can be taken in prevention stage to avoid finding the problems after the products are put into production and market. It will provide new ideas and new methods to improve the operation security of the engine, to prevent and forecast failure, and to estimate and control the risk.

Based on the ancient harmony idea, using the system theory, the man-water harmony index was brought up. It describes the harmonious level between man and water in cities. It quantitatively reflects the coordinating relationship between the water system and man city system of certain cities in certain periods. Improved Fuzzy Comprehensive Evaluation（ IFCE）, Improved Grey Relational Analysis（IGRA） and Analytic Network Process（ANP）are comprehensively used in calculating the man-water harmony index,building the IFCE-IGRA-ANP model. The index can be effectively used in sustainable development evaluations and water convervancy construction planning of modern cities.

This paper proposes a new risk assessment model on account of the fuzziness and uncertainty of risk factors in the reservoir after earthquake. The paper adopts methods of information entropy and fuzzy mathematics to assess risk level of the model. After analyzing the statistical data of earthquake-damaged reservoirs, we present comprehensive weight composed of importance and improved entropy weight. Base on comprehensive weight, we can adopt membership function to establish single factor evaluation of the model. Moreover, we combine fuzzy weighting method to assess risk level of a reservoir after earthquake. The result shows that risk level of the reservoir is high-risk. The case study verifies the practicability and rationality of the risk assessment method. Therefore, the method could be applied in the emergency rescue and reinforcement for reservoir after earthquake.

Ports represent a key element in the maritime transportation chain. Larger vessels and higher traffic volumes in ports might result in higher risks at the navigational level. Thus, the dire need for a comprehensive and efficient risk assessment method for ports is felt. Many methodologies have been proposed so far, but their application to aggregated vessel traffic risks for the overall assessment of ports is not developed yet. Hence, the development of an approach for the appraisal of the vessel traffic risks is still a challenging issue. This research aims to develop an assessment methodology to appraise the potential risk of accident occurrence in port areas at an aggregated level by creating a ‘Nautical Port Risk Index’ (NPRI). After identifying the main nautical risks in ports, the Analytic Network Process (ANP) is used to derive the risk perception (RP) weights for each criterion from data collected through surveys to expert navigators. The consequences related to each nautical risk are identified in consultation with risk experts. By combining the RP values and the consequence of each criterion for a time period, the NPRI is calculated. The risks in the Port of Rotterdam are presented in a case study, and the method has been validated by checking the results with experts in assessing nautical port risks from the Port of Rotterdam Authority. This method can be used to assess any new port design, the performance of different vessel traffic management measures, changes in the fleet composition, or existent ports using the Automatic Identification System (AIS) data.

The Relationship

Rockbursts are the sudden release of accumulated energy in surrounding rock of roadway and stope. Current studies on the rockburst mechanism are primarily focused on underground mining space and mining activities, whereas efforts have rarely been focused on regional geological dynamics. Mining activities in areas of energy accumulation under the influence of regional geological dynamics can easily cause mine dynamic disasters such as rockburst. The paper statistically analysed the relationship between geological dynamic environment factors (mining depth, tectonic stress, vertical crust movement, active faults, and the ratio of hard rock on the roof) and rockbursts in China and determined the relationship between various factors and the risk of rockbursts. Using a fuzzy comprehensive evaluation method and an analytic hierarchy process (AHP), a risk assessment method for rockburst based on the geological dynamic environment was established. This method was applied to assess the rockburst risk for the Tongxin coal mine in China, and it was evaluated as a weak rockburst risk. The result was consistent with the actual situation. The method provides a new concept for the evaluation and prediction of rockburst in new coal mines or new mining levels.
