5 results about "Ranking" patented technology

The invention discloses a control method of a nuclear power station safety level DCS. The control method includes the steps that two or more driving signals sent by equipment are received; the driving signals are subjected to priority ranking according to preset priority management logic; a first driving instruction is generated according to the ranked first driving signal so that an equipment driving device can execute operation according to the first driving instruction. According to the control method of the nuclear power station safety level DCS, in the control process of a nuclear power station safety level digital instrument control system, a multifunctional and intelligent control technology can be achieved. Besides, the invention discloses a multifunctional interface of the nuclear power station safety level DCS.

A mobile device includes a wireless communicating unit, an input unit, and a communication control module. The wireless communicating unit is configured to communicate via a plurality of kinds of wireless networks. The input unit is configured to receive an order for ranking and prioritizing one or more communicative conditions. The communication control module is configured to select a first wireless network from a plurality of available wireless network based on a the prioritization and ranking that is a result of ranking the communicative conditions, and to control the wireless communicating unit so as to transmit data via the first wireless network.

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.
