Marine high-end equipment reflects a country's comprehensive national strength. The safety assessment of it is very important to avoid accident either from human or facility factors. Attribute structure and assessment approach are two key points in the safety assessment of marine high-end equipment. In this paper, we construct a hierarchical attribute structure based on literature review and text mining of reports and news. The hierarchical attribute structure includes human, equipment, environment and management level. The correlations among these attributes are analyzed. The assessment standards of attributes are described in details. Different evaluation grades associated with attributes are transformed to a unified one by the given rules. As for the assessment approach, the evidential reasoning approach is applied for uncertain information fusion. Group analytical hierarchical process is used to generate attribute weights from a group of experts, where process aggregation method and result aggregation method are combined in a comprehensive way. The importance of expert is computed by the uncertainty measure of expert's subjective judgment. A drilling platform is finally assessed by the proposed attribute structure and assessment approach to illustrate the effectiveness of the assessment framework. © 2024 - IOS Press.

Statistical modeling for OLAP approximate query

引用

Journal of Computational Information Systems 2012年第9期8卷 3605-3612页

作者： Ni, Zhiwei Gao, Yazhuo Hu, Tanglei School of Management Hefei University of Technology Hefei 230009 China Key Laboratory of Process Optimization and Intelligent Decision-Making Ministry of Education Hefei 230009 China

From the perspective of supporting decision making, a statistical model is built in this paper in order to realize the tradeoff between the accuracy of OLAP queries and the efficiency of OLAP processes. Kernel density estimate and Copula method are employed on the multidimensional datasets to fit the marginal distribution and the joint distribution respectively, by which the dependence among dimensions is adequately explored. The synopsis information of OLAP multidimensional datasets is stored in the statistical model instead of keeping the raw data in the system, which drastically reduces the data storage space while the time spent on the OLAP query process is also reduced. The performance test and contrast experiment between Copula-based method and the classic GENHist histogram method are performed to verify that the statistical model proposed in this paper can provide the users with approximate answers of OLAP queries under the appropriate accuracy rate while improve the efficiency and flexibility of OLAP queries. © 2011 by Binary Information Press.

Equilibrium Conditions In Service Supply Chain

引用

Procedia Engineering 2011年 15卷 5100-5104页

作者： Fei Cheng Shanlin Yang Xijun Ma School of Management Hefei University of Technology Hefei 230009 China Key Laboratory of Process Optimization and Intelligent Decision-making Ministry of Education Anhui 230009China

Service supply chain features human players as service vendor, service integrator, customer and service resource. It tends to be digitally connected, such as consulting, e-business and integrated enterprises. Our study uses a formal model and simulations to develop the effect of a service supply chain on equilibrium computation. Two insights arise on how a network can obtain equilibrium computation: forming the network structure of service supply chain; exploring entities behavior and equilibrium conditions. These results highlight the importance for service supply chain of adapting its network structure to equilibrium and application.

Empirical analysis of the factors of government administrative preparation of China

Journal of Computational and Theoretical Nanoscience 2015年第11期12卷 4352-4357页

作者： Long, Zhu Jiang, Dai Changyong, Liang Management School of Hefei University of Technology Hefei230009 China Key Laboratory of Process Optimization and Intelligent Decision-Making Ministry of Education Hefei230009 China

A previous study conducted in Anhui Province by collecting data from 56 county-level governments in 2009 has shown that the factors of demographic, financial and geographical area have linear relationship with government administrative preparation. The administrative preparation of county-level government increased with the size of population, expenditure and geographical area. Geographical area has great impact on administrative preparation, followed by least impact of financial and population. Taking a county government for example, the geographical area is unchanged but household population changed slowly. So the main factor affected the total administrative preparation is financial expenditure. In the process of approving the county government administrative preparation should consider several factors, such as population movements around. The main objective of this study is to prove that administrative preparation should be based on resident population rather than household population. © 2015 American Scientific Publishers.

Using information entropy as weight determination approach in breast cancer case retrieval

Currently, the earlier detection, diagnosis and treatment to breast cancer still mainly depend on physicians' experience and knowledge. Case-Based Reasoning(CBR) mimics oncologists' real thinking process and therefore is appropriate to the diagnosis decision making. In CBR, weight derivation as a key step is commonly conducted by expert score approaches using Delphi method. The accuracy of case matching largely changes with the selection and experience of experts. In this paper, information entropy for weight determination is introduced into the CBR. We conduct experimental studies to compare the performance of Delphi method and information entropy. The results suggest that: generally, information entropy is a better approach to weight derivation.

This study presents a new hybrid ant colony algorithm (HACO) to solve an in integer linear programming formulation of the Cutting Stock Problem(CSP). The CSP is an important class combinatorial problem. It is appropriate to minimize the raw material used by industries for fulfilling customer's demands. In such cases, classic models for solving the cutting stock problem are useless. HACO consists of GDCP procedure and modified ACO (MACO). GDCP procedure provides dominative cutting patterns as MACO solution components, in MACO the pheromone trail is put on cutting patterns instead of items. MACO preserves cutting patterns and frequencies information under ants building solution procedure. Results obtained from computational experiments for ten benchmarks demonstrate that the performance of MACO is compared to that obtained using existing mete-heuristic algorithm.

Workflow mining is a concept in early era, it analyzes the workflow log in the control flow dimensions, to mining the actual process model, but ignores relationships among executors in workflow, hence it fails to effectively excavate the workflow log to find the implicit structure. In this paper, the organizational dimensions of workflow log will be the main focuses to be researched. The paper introduces executor similarity metrics and grid clustering to demonstrate the methods of the organizational structure mining based on executor similarity and organization mining based on grid clustering. Both of them are effective to extract the actual organizational structure from the workflow logs.

This paper considers how to design coordination strategies to achieve the coordination in decentralized supply chain, considering pricing, inventory and transportation cost simultaneously under the price sensitive environment. Based on a supplier-Stackelberg game structure, we analyze the non-cooperation decision model and design the algorithm. Then we propose the cooperation decision model and design the algorithm. Revenue sharing and price discount strategies are used to coordinate the decentralized supply chain. The experimental results show that both revenue sharing and price discount strategy can efficiently make the coordination of the supplier and the retailer.
