Selecting the most appropriate web service for information delivery from a pool of available web services is a multi-criteria decision making (MCDM) problem. Besides matching of functional requirements, quite a few non-functional criteria having different importance level would need to be considered for right selection of web services. Using literature review, expert interviews, and survey among practitioners,...
Integrating geospatial data acquired from diverse resources has been drawing a tremendous attention in recent years. Although many barriers have been successfully removed by the Open GIS technology, merely superimposing the acquired geospatial data together in the map interface certainly does not suffice the needs for correct application use. We argued that every distributed geospatial feature must...
To solve the problem that the logistics operation cost can't be controlled well by traditional methods, a DEA (data envelopment analysis) model is presented. The mechanism of the model is to make the logistics activities as a decision making unit to evaluate the efficiency of input and output. Base on the DEA result, the efficient logistics activities are reserved, and the inefficient ones are improved...
We address the problem of integrating information about multiple objects and their positions on a visual scene. A primate visual system has fewer difficulties in rapidly achieving integration, given even when presented with several objects. Here, we propose a neurally plausible mechanism for simultaneously coordinating the local decision-making process of “what”- and “where”-information...
Although the new type of network security incidents continue to occur, most security incidents are similar, the response methods have in common, so CBR (Case Based Reasoning) technology can be used to describe the successful experience of the past incident response. Based on past examples of how to develop rapid response strategy is the key to incident responses. Automated planning method can greatly...
Ergonomic evaluation of manually controlled devices is an important means of testing a man - machine interface matching in manned space medicine and engineering research. It's one of the comprehensive evaluation method based on Delphi, AHP and Grey systems. This study proposed a mathematical model combining subjective weights and objective weights, evaluated manually controlled devices quantitatively,...
With the development of technology, calculated amount especially in seismic data processing is increasing in virtual computing environment and the data size is astonishing. In this paper, based on the seismic data and the influence factors during the calculation, we present a suitable data partitioning strategy-the PGA (Pretreatment Genetic Algorithm) algorithm. The scheduling problem in virtual computing...
We study a class of decentralized team decision problems over discrete state spaces with non classical information structures. We present a simple class of problems, where an optimal solution can be obtained via coding. For the example presented, we explicitly construct a coding scheme, called the binary sum coding scheme, and show that it is optimal. This class of problems is motivated by a famous...
The code matrix enables to convert a multi class problem into an ensemble of binary classifiers. We suggest a new un-weighted framework for iteratively extending the code matrix which based on confusion matrix. The confusion matrix holds important information which is exploited by the suggested framework. Evaluating the confusion matrix at each iteration enables to make a decision regarding the next...
Structured management is an important management technique to decompose and synthesize large-scale complex projects. This article introduces the principles, the current research and connotation of structured management methods, based on which carries on specific study on project breakdown and proposes structured comprehensive breakdown method for large-scale complex projects. This article chooses...
The National Identification System (NIS), an initiative of the government to create a computerized database of Ghanaians and foreign nationals resident in Ghana using a biometric system of registration to captures the biodata of an individual and stores it in a database. The NIS is expected to provide some benefits such as development planning based on sufficient accurate population data, delivery...
Unequal Area Facility Layout Problem (UA-FLP) has been addressed by several methods. However, UA-FLP has only been solved regarding quantitative criteria. Our approach includes subjective features to UA-FLP, which are difficult to take into account with a classical heuristic optimization. For that, an Interactive Genetic Algorithm (IGA) is proposed that allows an interaction between the algorithm...
The paper based on digital city management platform, built emergency evacuation management model. First, gave the framework of digital city management platform, and then, describes the main steps of the design of digital city management platform, final, gave the emergency evacuation model based on Digital City management platform. The model based on knowledge base of emergency contingency plans, for...
This paper firstly defined what tacit knowledge is and analyzes its network characters in an organization. Then, taking a small high-tech enterprise as a case, we constructed its tacit knowledge transfer network with methods of SNA by using software Ucinet6.237 and Pajek2.0, and make quantitative research of the whole network, individual networks and clique analysis. Finally we put forward some optimization...
This paper studies the influence of the encoding and decoding on the result of the Job Shop problem under E/T indicators and improve the coding methods to make the optimal object span in order to adapt to different delivery windows earliness / tardiness scheduling problem. In this paper, The trapezoidal fuzzy number which has more representation as flexible operating processing time under fuzzy environment...
Granular computing, provides a new solution for qualitative SDG fault diagnosis not only in philosophy but also in technique. In this paper, granular matrix-based knowledge reduction algorithm is applied to simplify SDG model which transform the attribute reduction into simple binary matrix operation. The research fruits show the effective integration of SDG model and granular computing.
This paper presents a quantitative extension for the linear-time temporal logic LTL allowing to specify the number of states satisfying certain sub-formulas along paths. We give decision procedures for the satisfiability and model checking of this new temporal logic and study the complexity of the corresponding problems. Furthermore we show that the problems become undecidable when more expressive...
The conventional information used to guide drivers in selecting their driving paths is the shortest-distance path (SDP). However, driver path selection is a multiple criteria decision process. This paper presents a multiobjective path optimisation (MOPO) model to make a more precise simulation of the decision-making behaviour of driver path selection. Three single-objective path optimisation (SOPO)...
In order to reflect the dynamic, multi-objective and non-linear features and provide stronger decision-making support for urban spatial growth, this paper explores methods and technical route using genetic algorithm in urban spatial growth model, including encoding used for expressing urban growth individual, initial cluster setting for genetic algorithm operation beginning, fitness function design...
Recently, one of the main tools of decision maker (DM) preference incorporation in the multiobjective optimization (MOO) has been using reference points and achievement scalarizing functions (ASF). The core idea of these methods is converting the original multiobjective problem (MOP) into single objective problem by using ASF to find a single preferred point. However, many DMs not only interest in...
