Embodiment 1

[0030] An embodiment of the present invention provides a method for constructing a KPI level model, wherein KPI is a method for measuring process performance by setting, sampling, calculating, and analyzing key parameters at the input and output ends of a certain process within an organization. Objective-based quantitative indicators are a tool for decomposing an enterprise's strategic goals into operable long-term goals, and are the basis of enterprise performance management. KPI is a performance evaluation method that is generally valued in modern enterprises. In the present invention, KPI indicators are divided into electric energy consumption indicators and carbon emission indicators. Energy consumption is expressed as electricity consumption per unit output value, that is, energy consumption = total electricity consumption / total output value; carbon emission is expressed as carbon emissions per unit output value, that is, carbon emission = total carbon emissions / total outp...

Embodiment 2

[0039] Embodiment 2 of the present invention provides a method for evaluating energy consumption, figure 1 is a flowchart of the method, the method comprising:

[0040] S20: Use the method provided in Embodiment 1 to construct a KPI level model.

[0041] S21: Obtain the KPI index of the enterprise itself in different periods, and correspond the KPI index of each period to the corresponding KPI level in the KPI level model. The larger the KPI index, the higher the KPI level, and the higher the energy consumption of the enterprise. The smaller the KPI index, the lower the KPI level, and the smaller the energy consumption of the enterprise. figure 2 It is a comparison chart of Honghao Chemical's daily energy consumption level in a certain month. From the chart, you can see the daily KPI index, as well as the relationship between KPI index, temperature and holidays.

Embodiment 3

[0072] Embodiment 3 of the present invention provides a KPI grade model construction device, including: a first calculation module, which is used to calculate the average value according to the KPI index of the industry or enterprise in the past period of time; a query module, which is used to query the optimal KPI of a third party Index and the worst KPI index; the second calculation module is used to calculate the difference between the average value and the optimal KPI index, and simultaneously calculate the difference between the worst KPI index and the average value, and use The larger absolute value of the two differences is divided by 3 to obtain a grade difference; the model building module is used to set the average value as a benchmark, and sequentially increase the grade difference three times on the basis of the benchmark 1. Decrease the grade difference downwards three times, and construct seven grades centered on the average value.

Abstract

The invention provides a method and device for constructing a KPI (key performance indicator) hierarchical model, and energy consumption assessing method and system. The energy consumption assessing method comprises the following steps: constructing the KPI hierarchical model, evaluating the KPI indexes of an enterprise at different stages, the KPI indexes of different enterprises in a same industry, the KPI indexes of all the enterprises in a park, marking according to the historical energy consumption level of the enterprise, marking according to the energy consumption levels of the different enterprises in the same industry, marking according to the energy consumption levels of all the enterprises in the park, obtaining the comprehensive score of the enterprise according to the marking on the three aspects, giving a corresponding comprehensive evaluation result according to the comprehensive score of the enterprise, and giving corresponding suggestion according to the comprehensive evaluation result. By using the energy consumption assessing method provided by the invention, the energy consumption levels of the enterprise are evaluated in the three aspects of the own different stages of the enterprise, the condition of the enterprise in the same industry and the condition of the enterprise in the park; the evaluation foundation is more general; and in addition, by using the suggestion given through the comprehensive evaluation result, the enterprise can be enabled to adjust an energy usage action, so as to decrease energy consumption.

Description

technical field [0001] The invention relates to the field of enterprise energy consumption level evaluation, in particular to a method and device for constructing a KPI level model, and an energy consumption evaluation method and system. Background technique [0002] With the increasing impact of economic development and social activities on the environment, reducing energy consumption has received extensive attention in the process of economic development. [0003] In order to reduce energy consumption and save electricity, it is necessary to evaluate the energy consumption level of the enterprise, and the enterprise adjusts the energy consumption behavior according to the evaluation result, that is, the energy consumption evaluation result provides a decision-making basis for the enterprise demand side response and energy saving and consumption reduction. [0004] At present, enterprises can only evaluate energy consumption levels from their own historical data, that is, t...
