Description

Technical Field

[0001] The present invention belongs to the field of electric power materials, and relates to electric power material procurement technology, and specifically to an evaluation method and system for an intelligent procurement plan for electric power materials. Background Art

[0002] Power materials refer to the various equipment, instruments and materials required in the production, transmission and distribution process of the power industry, covering all kinds of materials required for the entire process from power generation to end-user use. In order to effectively manage the power material supply chain, improve procurement efficiency and reduce costs, the procurement plan aims to optimize the procurement process, enhance supplier management, reduce procurement risks, speed up delivery, etc. The evaluation of the procurement plan needs to comprehensively consider the improvement of procurement efficiency and cost savings, risk assessment, employee training evaluation and performance evaluation to measure the performance of the plan.

[0003] Under the current technical background, the procurement of power materials is characterized by long procurement cycles and large procurement quantities. In the actual material procurement process, the procurement plan only considers the initial cost factors such as material prices and delivery cycles, and lacks an evaluation of the actual use benefits and use costs of the invested power materials. In addition, the time cost of the evaluation work is relatively long. Therefore, how to achieve intelligent evaluation and intelligent adjustment of power material procurement plans on the basis of ensuring work efficiency is the problem; To this end, the present invention proposes a method and system for evaluating an intelligent procurement plan for electric power materials. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention aims to provide a method and system for evaluating smart procurement plans for electric power materials.

[0005] The technical problems to be solved by the present invention are: How to intelligently evaluate and adjust power material procurement plans.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: In a first aspect, a method for evaluating a smart procurement plan for electric power materials comprises the following steps: Step S101: The historical record module obtains historical material data of electric power materials and sends it to the historical analysis module via the server. The historical analysis module conducts a comprehensive analysis on the material usage of the electric power materials, obtains the material utility level of the electric power materials through the analysis, and sends it to the purchasing terminal via the server. Step S102, the purchasing terminal adjusts the purchasing plan of the power materials according to the material utility level. After the purchasing plan is formulated, the data acquisition module obtains the actual purchasing data of the power materials and sends it to the benefit analysis module via the server; Step S103, the test module is used to conduct a comprehensive test on the use of the power materials after the replacement of the procurement plan, and the actual test data of the power materials obtained by the test is sent to the benefit analysis module via the server; Step S104, the benefit analysis module conducts a comprehensive analysis on the benefits of the procurement plan, and obtains the revised effect of the procurement plan corresponding to the power materials through the analysis, and sends it to the procurement terminal via the server. The procurement terminal adjusts the procurement plan according to the revised effect of the procurement plan.

[0007] Furthermore, the historical material data includes material type, material procurement cycle, material procurement quantity, and periodic usage times and periodic failure times of each power material; The actual procurement data includes the purchase unit price of power materials, logistics distance, logistics unit price and maintenance costs; The actual test data includes the actual usage times and actual failure times of the power materials in the control samples and the test samples.

[0008] Furthermore, in step S101, the analysis process of the history analysis module is as follows: Obtain the material type of the power material, and select the corresponding material loss coefficient according to the material type of the power material; Obtain the material procurement cycle, material procurement quantity, and the periodic usage times and periodic failure times of each power material, and calculate the periodic utility value of the power material; Comparing the periodic utility value of the electric power material with the periodic utility threshold value; If the cycle utility value is less than or equal to the first cycle utility threshold, the material utility level of the corresponding electric power material is determined to be the first material utility level; If the cycle utility value is greater than the first cycle utility threshold and less than or equal to the second cycle utility level, the material utility level of the corresponding electric power material is determined to be the second material utility level; If the period utility value is greater than the second period utility threshold, it is determined that the material utility level of the corresponding electric power material is the third material utility level.

[0009] Furthermore, the corresponding relationship between the material type and the material loss coefficient is as follows: If the material type of the power material is fixed-point material, the corresponding material loss coefficient is s3; If the material type of the power material is dispatching material, the corresponding material loss coefficient is s2; If the material type of the power material is consumable material, the corresponding material loss coefficient is s1; Among them, the values ​​of s1, s2 and s3 are all greater than zero, s1<s2<s3, and the material loss coefficient reflects the degree of impact of the loss of power materials.

[0010] Furthermore, the values ​​of the first cycle utility threshold and the second cycle utility threshold are both greater than zero, the first cycle utility threshold is less than the second cycle utility threshold, the effective utilization rate of materials at the first material utility level is lower than the effective utilization rate of materials at the second material utility level, and the effective utilization rate of materials at the second material utility level is lower than the effective utilization rate of materials at the third material utility level.

[0011] Furthermore, in step S102, the corresponding relationship between the procurement plan and the material utility level is as follows: If the material utility level of the electric power material is the first material utility level, the number of periodic purchases of the corresponding electric power material is immediately reduced and a purchase replacement signal is generated; If the material utility level of the electric power material is the second material utility level, the cycle utilization efficiency and material loss rate of the electric power material in the material procurement cycle are obtained for numerical comparison; If the cycle utilization efficiency is greater than or equal to the material loss rate, the cycle purchase quantity of the corresponding power materials will be increased; If the cycle utilization efficiency is less than the material loss rate, the cycle purchase number of the corresponding power material is increased and a purchase replacement signal is generated; If the material utility level of the electric material is the third material utility level, no additional operation is performed.

[0012] Furthermore, in step S103, the test process of the input test module is as follows: The power materials are divided into a working group and a test group. The ratio of the number of power materials in the working group, control sample and test sample is 8:1:1, that is, the number of control samples and the number of test samples of power materials are equal; The power materials in the test group are respectively configured in test scenarios with the same personnel configuration and the same operation content, and the actual test data of the power materials are monitored for the same duration to obtain the actual test data of the power materials.

[0013] Furthermore, in step S104, the analysis process of the benefit analysis module specifically includes: Obtain the purchase price, logistics distance, logistics price and maintenance cost of power materials; Obtain the actual usage times and actual failure times of the power materials in the control sample, and calculate the comprehensive benefit value of the control sample in the power materials; Similarly, the actual usage times and actual failure times of the power materials in the test samples are obtained, and the comprehensive benefit value of the test samples in the power materials is calculated; Compare the comprehensive benefit values ​​of the control samples and the test samples in the power materials; If the comprehensive benefit value of the control sample is greater than or equal to the comprehensive benefit value of the test sample, the correction effect of the corresponding procurement plan of the power materials is determined to be invalid; If the comprehensive benefit value of the control sample is less than the comprehensive benefit value of the test sample, the correction effect of the corresponding procurement plan of power materials is determined to be effective.

[0014] Furthermore, in step S104, the work content of the purchasing terminal specifically includes: If the revised effect of the procurement plan for power materials is invalid, the revised plan will be withdrawn and other types of power materials will be selected again; If the correction effect of the corresponding procurement plan for electric power materials is effective, the current modified plan will be executed and the procurement volume will be adaptively increased.

[0015] In the second aspect, a power material intelligent procurement scheme evaluation system includes: The historical record module is used to obtain the historical material data of power materials; The historical analysis module is used to conduct a comprehensive analysis of the material usage of power materials; Data acquisition module, used to obtain actual procurement data of power materials; The test module is used to conduct comprehensive tests on the use of power materials after replacing the procurement plan; Benefit analysis module, used to conduct comprehensive analysis of the benefits of the procurement plan; The procurement terminal is used to adjust the procurement plan according to the material utility level and the correction effect of the procurement plan.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: The present invention first obtains historical material data of electric power materials through a historical record module and sends it to a historical analysis module, then uses the historical analysis module to conduct a comprehensive analysis on the material usage of electric power materials, obtains the material utility level of the electric power materials through the analysis and sends it to a purchasing terminal, and then the purchasing terminal adjusts the purchasing plan of the electric power materials according to the material utility level. After the purchasing plan is formulated, the actual purchasing data of the electric power materials is obtained through a data acquisition module and sent to a benefit analysis module, and then uses an input test module to conduct a comprehensive test on the usage of the electric power materials after replacing the purchasing plan, and the actual test data of the electric power materials obtained through the test is sent to the benefit analysis module, and finally the benefit situation of the purchasing plan is comprehensively analyzed through the benefit analysis module, and the correction effect of the corresponding purchasing plan of the electric power materials is obtained through the analysis. The present invention realizes intelligent evaluation and intelligent adjustment of the purchasing plan of electric power materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figure 1-Figure 3 As shown, the technical solution provided by the present invention is: a method for evaluating a smart procurement plan for electric power materials, comprising the following steps: Step S101: The historical record module obtains historical material data of electric power materials and sends it to the historical analysis module via the server. The historical analysis module conducts a comprehensive analysis on the material usage of the electric power materials, obtains the material utility level of the electric power materials through the analysis, and sends it to the purchasing terminal via the server. Step S102, the purchasing terminal adjusts the purchasing plan of the power materials according to the material utility level. After the purchasing plan is formulated, the data acquisition module obtains the actual purchasing data of the power materials and sends it to the benefit analysis module via the server; Step S103, the test module is used to conduct a comprehensive test on the use of the power materials after the replacement of the procurement plan, and the actual test data of the power materials obtained by the test is sent to the benefit analysis module via the server; Step S104, the benefit analysis module conducts a comprehensive analysis on the benefits of the procurement plan, and obtains the revised effect of the procurement plan corresponding to the power materials through the analysis, and sends it to the procurement terminal via the server. The procurement terminal adjusts the procurement plan according to the revised effect of the procurement plan.

[0021] The above method involves a server, which is connected to a history recording module, a history analysis module, a data acquisition module, an investment test module, a benefit analysis module and a purchasing terminal; In practice, the power materials are specifically various materials and equipment required in the process of power production, transmission, distribution and use, such as transformers, switchgear, insulators, wires, power generation equipment, power distribution equipment, power electronic devices, power meters and power maintenance equipment. In this embodiment, the power materials are preferably power distribution equipment; The historical record module is used to obtain historical material data of electric power materials and send the historical material data to the server, and the server sends the historical material data of electric power materials to the historical analysis module; Among them, historical material data include the material type, material procurement cycle, material procurement number, and cycle usage times and cycle failure times of each power material. The material type corresponds to the working mode of the power material. The material type includes fixed-point materials, dispatching materials and consumable materials. Fixed-point materials are specifically large-scale power equipment set at fixed locations. Dispatching materials are specifically tools and materials that can be flexibly transferred to different work scenes. Consumable materials are specifically disposable replacement components and maintenance work tools used for maintenance in the power production process. The material procurement cycle is the procurement interval duration of the corresponding power materials. The cycle usage times are the number of times the power materials are used within the material procurement cycle. It should be specifically noted that if the material type is fixed-point materials, the usage time of the corresponding power materials in the material procurement cycle will be used as the cycle usage times. If the material type is consumable materials, the material consumption of the corresponding power materials in the material procurement cycle will be used as the cycle usage times. The cycle failure times are the number of times the corresponding power materials fail, are damaged or are scrapped during the material procurement cycle.

[0022] In this embodiment, the historical analysis module is used to conduct a comprehensive analysis of the material usage of power materials. The specific analysis process is as follows: Get the material type of the power material, and select the corresponding material loss coefficient si according to the material type of the power material, where i is the number of the material type and i is a non-zero natural number. The corresponding relationship between the material type and the material loss coefficient is as follows: If the material type of the power material is fixed-point material, the corresponding material loss coefficient is s3; If the material type of the power material is dispatching material, the corresponding material loss coefficient is s2; If the material type of the power material is consumable material, the corresponding material loss coefficient is s1; Among them, the values ​​of s1, s2 and s3 are all greater than zero, s1<s2<s3, and the material loss coefficient reflects the degree of influence of the loss of power materials; Obtain the material procurement cycle ZQi, material procurement number GSi, and the periodic usage times SYir and periodic failure times GZir of each power material. r is the number of the power material, and the upper limit of r is equal to the material procurement number. Calculate the periodic utility value XYi of the power material according to the formula. The specific formula is as follows: ; Among them, si is the material loss coefficient of the corresponding power resources, and the values ​​of si include s1, s2 and s3. s1 corresponds to the material type of power materials, which is consumable materials; s2 corresponds to the material type of power materials, which is dispatching materials; s3 corresponds to the material type of power materials, which is fixed-point materials; XLi is the cycle utilization efficiency of power materials in the material procurement cycle; SHi is the material loss rate of power materials in the material procurement cycle. The calculation formula involved is as follows: ; ; Comparing the periodic utility value of the electric power material with the periodic utility threshold value; If the cycle utility value is less than or equal to the first cycle utility threshold, the material utility level of the corresponding electric power material is determined to be the first material utility level; If the cycle utility value is greater than the first cycle utility threshold and less than or equal to the second cycle utility level, the material utility level of the corresponding electric power material is determined to be the second material utility level; If the cycle utility value is greater than the second cycle utility threshold, the material utility level of the corresponding electric power material is determined to be the third material utility level; Among them, the values ​​of the first cycle utility threshold and the second cycle utility threshold are both greater than zero, the first cycle utility threshold is less than the second cycle utility threshold, the effective utilization rate of materials at the first material utility level is lower than the effective utilization rate of materials at the second material utility level, and the effective utilization rate of materials at the second material utility level is lower than the effective utilization rate of materials at the third material utility level; The historical analysis module sends the material utility level of the electric power material to the server, and the server sends the material utility level of the electric power material to the purchasing terminal.

[0023] The purchasing terminal adjusts the purchasing plan of the power materials according to the material utility level. The corresponding relationship between the purchasing plan and the material utility level is as follows: If the material utility level of the electric power material is the first material utility level, the number of periodic purchases of the corresponding electric power material is immediately reduced and a purchase replacement signal is generated; If the material utility level of the electric power material is the second material utility level, the cycle utilization efficiency and material loss rate of the electric power material in the material procurement cycle are obtained for numerical comparison; If the cycle utilization efficiency is greater than or equal to the material loss rate, the cycle purchase quantity of the corresponding power materials will be increased; If the cycle utilization efficiency is less than the material loss rate, the cycle purchase number of the corresponding power material is increased and a purchase replacement signal is generated; If the material utility level of the power material is the third material utility level, no additional operation is performed; It is understandable that when the material utilization efficiency of electric power materials is low and the material loss rate is high, consideration should be given to using other models of the same type of electric power materials to replace the electric power materials in use. When the material utilization efficiency is acceptable but the material loss rate is high, consideration should be given to increasing the purchase quantity and, at the same time, incorporating the selection of other models of electric power materials into the procurement plan.

[0024] As a further solution of the present invention, after the procurement plan is formulated, the data acquisition module is used to acquire the actual procurement data of the power materials and send the actual procurement data to the server, and the server sends the actual procurement data of the power materials to the benefit analysis module; It should be noted that the actual procurement data includes the purchase unit price, logistics distance, logistics unit price and maintenance costs of power materials. The purchase unit price is the purchase price of a single piece of power materials, the logistics unit price is the unit price of logistics services, the logistics distance is the transportation distance between the shipping location and the receiving location of the power materials, and the maintenance cost is the cost expenditure for daily maintenance and fault repair of power materials.

[0025] The input test module is used to conduct a comprehensive test on the use of power materials after the replacement of the procurement plan. The specific test process is as follows: In this embodiment, the electric power materials are divided into a working group and a test group. The working group is the corresponding electric power materials in the original procurement plan. The test group includes a control sample and a test sample. The control sample is the corresponding electric power material in the original procurement plan, and the test sample is the corresponding electric power material in the new procurement plan. The ratio of the number of electric power materials in the working group, the control sample and the test sample is 8:1:1, that is, the numerical value of the number of control samples and the number of test samples of the electric power materials is equal; The power materials in the test group are respectively configured in test scenarios with the same personnel configuration and the same operation content, and the actual test data of the power materials are monitored for the same duration. The actual test data includes the actual usage times RYir and the actual failure times RGir of the power materials in the control sample and the test sample; The input test module sends the actual test data of the electric power materials to the server, and the server sends the actual test data of the electric power materials to the benefit analysis module.

[0026] In this embodiment, the benefit analysis module is used to conduct a comprehensive analysis of the benefits of the procurement plan. The specific analysis process is as follows: Obtain the purchase unit price CJi, logistics distance JLi, logistics unit price WLi and maintenance cost Whi of power materials; The actual usage times RYir and actual failure times RGir of the power materials in the control sample are obtained, and the comprehensive benefit value XYi of the control sample in the power materials is calculated according to the formula. The specific formula is as follows: ; Similarly, the actual usage times RYi'r and actual failure times RGi'r of the power materials in the test sample are obtained, and the comprehensive benefit value XYi' of the test sample in the power materials is calculated according to the formula. The specific formula is as follows: ; It can be understood that R is the number of power materials in the control sample, R=GSi / 10, that is, R is also the number of power materials in the test sample; Compare the comprehensive benefit values ​​of the control samples and the test samples in the power materials; If the comprehensive benefit value of the control sample is greater than or equal to the comprehensive benefit value of the test sample, the correction effect of the corresponding procurement plan of the power materials is determined to be invalid; If the comprehensive benefit value of the control sample is less than the comprehensive benefit value of the test sample, the correction effect of the corresponding procurement plan of the power materials is determined to be effective; The benefit analysis module sends the revised effect of the procurement plan corresponding to the power materials to the server, and the server sends the revised effect of the procurement plan corresponding to the power materials to the procurement terminal; The procurement terminal further adjusts the procurement plan according to the revised effect of the procurement plan. The specific work content includes: If the revised effect of the procurement plan for power materials is invalid, the revised plan will be withdrawn and other types of power materials will be selected again; If the revised effect of the corresponding procurement plan for power materials is effective, the current revised plan will be implemented and the procurement volume will be increased adaptively; This implementation first obtains the historical material data of the power materials through the history record module and sends it to the history analysis module, then uses the history analysis module to conduct a comprehensive analysis on the material usage of the power materials, and obtains the material utility level of the power materials through the analysis and sends it to the procurement terminal, and then the procurement terminal adjusts the procurement plan of the power materials according to the material utility level. After the procurement plan is formulated, the actual procurement data of the power materials is obtained through the data acquisition module and sent to the benefit analysis module, and then the use of the power materials after the replacement of the procurement plan is comprehensively tested by the input test module, and the actual test data of the power materials obtained by the test is sent to the benefit analysis module, and finally the benefit situation of the procurement plan is comprehensively analyzed through the benefit analysis module, and the correction effect of the corresponding procurement plan of the power materials is obtained through the analysis, so as to realize the intelligent evaluation and intelligent adjustment of the procurement plan of the power materials; In this application, if corresponding calculation formulas appear, the above calculation formulas are all dimensionless and take their numerical calculations. The weight coefficients, proportional coefficients and other coefficients in the formulas are set to a result value obtained by quantifying each parameter. The size of the weight coefficient and the proportional coefficient can be determined as long as it does not affect the proportional relationship between the parameter and the result value.
