[0009] The final target layer score is calculated according to the weight of the criterion layer to obtain the evaluation result.

[0010] Furthermore, the goal level is performance evaluation, and the criteria levels are social responsibility, finance, customers, internal processes, and learning and growth;

[0042] Embodiment 2:

[0043] Please refer to Figure 2 As shown: A method for evaluating the performance of an electric power enterprise comprises the following steps:

[0044] Step 1: First, use the balanced scorecard to calculate the weights of different indicators.

[0045] A hierarchical model is established and an indicator evaluation system is constructed as shown in the following table.

[0046]

[0047]

[0048] Construct a judgment matrix with two factors i and j, A = (a ij )n×n, where a ij Indicates the importance of the i-th factor compared to the j-th factor. The fuzzy judgment matrix a of any two elements on the criterion layer ij It can be expressed as the meaning of the importance scale, where the values ​​of the membership values ​​of the importance of the two elements can be referred to the table below to check whether the established fuzzy matrix is ​​consistent.

[0049]

[0050] Normalize the judgment matrix by column, that is, normalize each column of the judgment matrix A:

[0051]

[0052] Add row by row to get the sum vector:

[0053]

[0054] Normalizing the obtained sum vector, we can get the indicator weight vector:

[0055]

[0056] Calculate the largest eigenvalue λ max :

[0057]

[0058] Perform consistency check and introduce random consistency index RI:

[0059]

[0060] When CR<0.1, the consistency of the judgment matrix is ​​considered acceptable, otherwise the judgment matrix should be appropriately modified.

[0061] The application of the balanced scorecard fully embodies strategic and forward-looking nature. First of all, from the perspective of the four dimensions, the financial dimension measures the company's past achievements and is an indicator dimension that focuses on results; the customer, internal process, and learning and growth dimensions focus on the dynamic process of the company's operations and are process indicators. By combining result indicators and process indicators, the balanced scorecard can evaluate the company's performance from multiple angles, comprehensively and objectively. Secondly, the advantage of the balanced scorecard is not only that it integrates financial and non-financial indicators, but more importantly, it can analyze the company's own strategic implementation path and clearly show whether the company is correctly executing its plan by generating a series of performance measurement indicators;

[0062] Step 2, obtain the actual values ​​and target values ​​of five indicators at the social responsibility level, including clean energy grid-connected capacity, clean energy utilization rate, number of local jobs supported, support for rural revitalization, and safety accident reduction rate.

[0063] Obtain the actual and target values ​​of four financial indicators including profit growth rate, return on equity, operating cash ratio and economic added value.

[0064] Obtaining customer levels includes the actual and target values ​​of two indicators: customer satisfaction, customer complaint rate and market share.

[0065] The actual and target values ​​of four indicators at the internal process level are obtained, including line loss rate, comprehensive voltage qualification rate, power supply reliability rate, and emergency response time.

[0066] Obtaining the learning and growth level includes the actual and target values ​​of four indicators: employee training rate, employee retention rate, R&D investment level, and digital development level.

[0067] Step 3, define A as the target layer score, B i is the criterion layer score, C ij is the index layer score, W i is the criterion layer weight, W ij is the index layer weight, V j is the actual value of the indicator layer, T j is the target value of the indicator layer;

[0068] The positive indicator score of the calculation indicator layer is:

[0069] C ij =V j / T j *W ij

[0070] The negative indicator score of the calculation indicator layer is:

[0071] C ij =T j / V j *W ij

[0072] The calculation criteria layer score is:

[0073]

[0074] The target layer score is calculated as:

[0075]

[0076] According to the values ​​of the above five criteria layers, the total score of the target layer is calculated to obtain the evaluation result.

[0077] In the example of the present invention, firstly, based on the balanced scorecard, the weights of different indicators are calculated, and the dimensions are eliminated. At the same time, negative indicators are recorded. The value of the social responsibility level is calculated by the actual values ​​and target values ​​of the clean energy grid-connected capacity, clean energy utilization rate, number of local employment supported, rural revitalization support, and safety accident reduction rate, as well as the corresponding weights. The value of the financial level is calculated by the actual values ​​and target values ​​of the profit growth rate, return on net assets, operating cash ratio, and economic added value, as well as the corresponding weights. The value of the customer level is calculated by the actual values ​​and target values ​​of customer satisfaction, customer complaint rate, and market share, as well as the corresponding weights. The value of the internal process level is calculated by the actual values ​​and target values ​​of the line loss rate, comprehensive voltage qualification rate, power supply reliability rate, and emergency response time, as well as the corresponding weights. The value of the learning and growth level is calculated by the actual values ​​and target values ​​of the line loss rate, comprehensive voltage qualification rate, power supply reliability rate, and emergency response time, as well as the corresponding weights. Finally, the total score of the target level is calculated based on the values ​​of the above five criterion levels to obtain the evaluation result.

[0078] In summary, the present invention introduces an automated performance appraisal model through data indicator technology. The indicators cover all aspects and support the visual display of performance appraisal results. It is convenient and fast, and can greatly reduce the cost of financial accounting communication, improve work efficiency, realize company value creation, and meet the requirements of company value management and early warning.

[0079] The present invention can also provide a computer device, including a processor and a memory, the memory is used to store a computer executable program, the processor reads the computer executable program from the memory and executes it, and when the processor executes the computer executable program, it can implement the power enterprise performance appraisal and evaluation method described in the present invention.

[0080] On the other hand, the present invention provides a computer-readable storage medium, in which a computer program is stored. When the computer program is executed by a processor, the power enterprise performance assessment and evaluation method described in the present invention can be implemented.
