It is important for most oil companies to focus on the core assets which are oil and gas reserves so as to avoid risk posed by some factors such as oil prices and costs, etc. This paper will set up a model related to investment in upstream business based on system dynamics principles and predict the size and structure of investment in upstream business with computer simulation method. It demonstrates...
In order to escape of risk and gain high returns, it is important for oil companies to determine the scale and structure of investment in upstream business. By introducing system dynamic principles, this paper builds a system dynamics model of upstream investment decision on basis of the oil company's practice in China. Empirical results show that total investment scale will decline and the proportion...
Through analyzing the factors affecting software trustworthy, established the index system of trustworthy software estimation. Apply Analytic Hierarchy Process (AHP) to determine the relative importance of factors and indicator items affecting software trustworthy, and then determine the score of estimation index system through fuzzy estimation model, use the combination of both to measure software...
Considered actions of Virtual battlefield individual with the intelligence and autonomy characteristic, internal factors that influence personnel external behavior were broken down into mate-Agents with considering behavior functions, and a battlefield individual behavioral model was advanced by aggregating mate-Agents. Mate-Agent structure was accomplished by intelligent model based on its main features,...
Under the background of formation cooperative antiship combat, theory of MAS (Multi-agent System) was introduced into the decision-making process, the general commander, formation commander as well as each operational platform were described as agents, the formation cooperative anti-ship combat agent model was established, then after the analysis of anti-ship combat mission planning process, framework...
The reforms of the agricultural irrigation management become the important content of the construction of the conservation-minded society and new socialist countryside, however, the traditional management of client/server mode can't meet the requirements. Consequently, the optimization of the irrigation management is inevitable according to the development of the irrigation facilities and the complication...
Through analyzing basic characters of software process, from three dimensions: software process products, software process actions and software entities, this paper establishes the measurement indicators system of software process quality trustworthiness, and introduces the measurement model of software process trustworthiness. Instances studies show the model can not only evaluate the trustworthy...
This paper introduces geography information system (GIS) into intelligent decision support system (IDSS) and proposes a 4 database and 1 machine frame model. On this basis we design the target assignment intelligent decision support system (TAIDSS), realize the close combination of IDSS, GIS and decision-making model, then we propose an intelligent target assignment decision model which contains knowledge...
Through analyzing the basic characters of Trustworthy Software, the index system of Trustworthy Software Process Measurement is set up, the correlation among Trustworthy Software, Trustworthy Process and Measurement Indexes is described formally, the model of Trustworthy Process Improvement and Measurement is introduced. Some instances researches show the model can not only estimate the trustworthy...
As two major performance measures, software productivity and quality convey critical information in supporting many decision making situations during project planning, management, as well as process/organization benchmarking processes. However, there is a lack of investigation on these performance measures with respect to enhancement projects, this leads to, in many enhancement/maintenance cases,...
The classical decision theory is based on the assumption that rational decision makers have full perceptibility. But real-life people always have bounded perceptibility. After reviewing some important results of the classical decision theory, this article describes a kind of bounded perceptual phenomenon between interrelated sub-problems of a complicated problem and established bounded perceptual...
