Risk Analysis Technique on Inconsistent Interview Big Data Based on Rough Set Approach

Journal of Data Analysis and Information Processing 2016年第3期4卷 101-114页

作者： Riasat Azim Abm Munibur Rahman shawon Barua Israt Jahan School of Computer Science & Engineering Wuhan University of Technology Wuhan China School of Management Wuhan University of Technology Wuhan China Infolytx Inc. Dhaka Bangladesh East West University Dhaka Bangladesh

Rough set theory is relativly new to area of soft computing to handle the uncertain big data efficiently. It also provides a powerful way to calculate the importance degree of vague and uncertain big data to help in decision making. Risk assessment is very important for safe and reliable investment. Risk management involves assessing the risk sources and designing strategies and procedures to mitigate those risks to an acceptable level. In this paper, we emphasize on classification of different types of risk factors and find a simple and effective way to calculate the risk exposure.. The study uses rough set method to classify and judge the safety attributes related to investment policy. The method which based on intelligent knowledge accusation provides an innovative way for risk analysis. From this approach, we are able to calculate the significance of each factor and relative risk exposure based on the original data without assigning the weight subjectively.

Shrimps are recognized as the white gold of Bangladesh because it is the second largest export earning product after garments *** brown shrimp(***)have high growth rates together with that they tolerate wide ranges of salinity and environmental parameters which makes them highly attractive for culture *** purposes of this research were to assess the cultural performance and economic profitability of brown shrimp(Metapenaeus monoceros)in brackish water *** research lasted from February to June 2020 under three different stocking densities such as 35,45 and 55 individuals/m2 in treatments T1,T2 and T3 at Bangladesh Fisheries Research Institute,Brackishwater Station,Paikgacha,*** 90 days culture periods the total production was 1703.32±144.48,2768.25±167.63 and 2535.03±253.52 kg/ha in T1,T2 and T3 respectively which was significantly higher(p<0.05)in T2 compared to T1 and *** cost ratio(BCR)was 0.32,0.87 and 0.52 in T1,T2 and T3 respectively and found significantly higher(p<0.05)in T2 than T1 and *** cultural performance and economic analysis imply that brown shrimp(***)with a stocking density of 450000 individuals/ha might be environment conciliatory and economically enduring in coastal areas of Bangladesh.
