Problems solved by technology
[0005] At present, there are few studies on oilfield business evaluation, and a scientific and reasonable evaluation method is lacking. The present invention provides a comprehensive evaluation method based on the improved entropy weight gray correlation analysis method, using the relevant use information of business components as evaluation indicators. It can better reflect the real actual needs of users, and make the evaluation results biased towards user needs, thereby improving the accuracy of evaluation. It is of great significance for oilfield companies to strengthen the management of oilfield business components, optimize business components, and improve service quality. The selection and combination of components serves as a guide

Embodiment Construction
[0034] The present invention will be further described in detail below with reference to the accompanying drawings and examples, but the embodiments of the present invention are not limited to the scope indicated by the examples.
[0035] The first step: according to figure 1 In the process shown, firstly, the index attributes of the oilfield business components are counted, and the evaluation index is determined. The following data are given in the example:
[0036]
[0037]
[0038] Step 2: According to the index data of each oilfield business component, establish an evaluation matrix A=(a ij ) 6×3 :
[0039]
[0040] Step 3: Analyze the attributes of each evaluation index. Generally, the larger the number of visits, application scope, and user evaluation, the better, that is, the positive index. Transform the original matrix A into a normalized evaluation matrix X. Using the normalization method of Formula 1, the normalized evaluation matrix X=(x ij ) 6×3 : ...

The invention belongs to the technical field of comprehensive evaluation, in particular to an oilfield service component evaluation method based on an improved entropy weight gray correlation analysismethod. The method includes such steps as A, collecting the usage log of oilfield service component, filtering the log content and counting the information of related service component, and selectingevaluation index from said log; B, establishing an evaluation matrix according to that evaluation index data of each oilfield service component; C. according to the attribute types of each evaluationindex, different methods are selected for standardization, and the original evaluation matrix is converted into a standardized evaluation matrix; D. calculating by using that entropy value method toobtain the objective weight of each evaluation index; E. improving that grey relational analysis method by changing the calculation formula of the relational degree, and combine the index weight information to construct a comprehensive evaluation model; F. using that comprehensive evaluation model to evaluate the oilfield service components, and obtain the evaluation ranking. The invention integrates the entropy value method and the grey relational analysis method, has the advantages of objective evaluation results and less sample requirements, can be used for the evaluation of oilfield service components, realizes the measurability of the evaluation of oilfield service components, and provides an important reference for selecting high-quality oilfield service components.
Description
technical field [0001] The invention belongs to the technical field of comprehensive evaluation, can be used to realize the quantifiable evaluation of oil field business components, optimize the oil field business components, and specifically relates to an evaluation method of oil field business components based on an improved entropy weight gray correlation analysis method. Background technique [0002] With the continuous development of computer technology, the environment faced by modern oilfield enterprises is becoming more and more complex, and most of their information systems are multi-platform and multi-system complex systems. This requires that in the Internet environment, the implementation system is loosely coupled, cross-platform, language-independent, and specific interface-independent, and it must provide reliable access to applications. [0003] The emergence of services has brought surprises to people. This technology can interoperate in different operating e...
