Description

Technical Field

[0001] This invention relates to the field of green technology in railway engineering, and in particular to a method and storage medium for evaluating the coupling and coordination degree of green technologies throughout the entire life cycle of railways. Background Technology

[0002] With increasing societal demands for environmental protection, the need for energy conservation and emission reduction in the transportation sector is becoming increasingly prominent. Due to its large capacity and low energy consumption, railway transportation has significant advantages in achieving energy conservation and emission reduction within the comprehensive transportation system. To fully leverage these advantages, a systematic evaluation and optimization of the green technologies employed in railway transportation is necessary.

[0003] Railway engineering projects are typically characterized by long track lengths, extended construction and operation periods, and the involvement of numerous professional fields. In such complex systems engineering projects, the application and practice of green technologies often exhibit a fragmented nature, meaning that various technologies are often limited to independent optimization and application within a single stage such as design, construction, or operation. Particularly in the early design phase of a project, the selection of technical solutions often focuses on meeting immediate functional, cost, and safety requirements, while lacking a systematic and forward-looking assessment and comprehensive consideration of the potential comprehensive green benefits (such as long-term energy conservation, emission reduction, and ecological impact) that the selected technologies may generate throughout their entire life cycle (covering all stages of design, construction, and operation).

[0004] Currently, most evaluation methods for green technologies in railway engineering still follow traditional approaches, separating the design, construction, and operation phases for independent evaluation. These methods typically focus on the technical performance or environmental compliance within a single phase, resulting in a limited evaluation dimension and failing to effectively reveal and quantify the interactions and synergies between green technologies at different phases. Their limitation lies in the lack of a systematic and collaborative perspective, making it difficult to comprehensively assess the effectiveness of green technology clusters spanning multiple phases and involving various disciplines from the perspective of overall life-cycle optimization. Therefore, traditional methods cannot scientifically support the goal of maximizing overall green benefits when making technical decisions early in a project.

[0005] In conclusion, to improve the overall level of green development in railway engineering, it is urgent to break through the traditional barriers between the three stages of design, construction, and operation, innovate evaluation methods, and systematically coordinate, evaluate, and optimize the selection and application of green technologies from a life-cycle perspective. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies in which it is difficult to conduct forward-looking assessments and decision support for the full life-cycle synergistic benefits of green technologies in the early stages of a project, and to provide a method and storage medium for evaluating the coupling coordination degree of green technologies throughout the entire life cycle of railways.

[0007] In a first aspect, the present invention provides a method for evaluating the coupling coordination degree of green technologies throughout the entire life cycle of railways, comprising the following steps:

[0008] Based on the resource and environmental constraints of the target project, acquire green technologies suitable for the target project; Based on a pre-set green technology analysis model, the green technologies of the target project are processed to obtain green technologies for the entire life cycle of the railway. Based on a pre-set green technology evaluation model, the evaluation indicators for the green technologies throughout the entire life cycle of the railway are determined. Based on the evaluation indicators and the preset multi-coupling coordination degree assessment model, the coupling coordination degree of the green technologies throughout the railway life cycle is calculated.

[0009] Preferably, the railway's entire life cycle includes: the design phase, the construction phase, and the operation phase. The green technologies of the railway's entire life cycle include a two-way information mapping and feedback path between the design phase and the construction phase, and between the design phase and the operation phase.

[0010] Preferably, the preset green technology evaluation model is a multi-dimensional hierarchical evaluation model, wherein the multi-dimensional dimensions include technical dimensions, stage dimensions, functional dimensions, and management dimensions; determining the evaluation indicators of the green technology throughout the railway's life cycle specifically includes: analyzing and extracting the technical characteristics of the green technology throughout the railway's life cycle based on the multi-dimensional hierarchical evaluation model, thereby determining multiple levels of evaluation indicators, wherein the multiple levels of evaluation indicators include primary indicators, secondary indicators corresponding to each primary indicator, and tertiary indicators corresponding to each secondary indicator.

[0011] Furthermore, the primary indicators include: technical coordination evaluation indicators, phase coordination evaluation indicators, functional coordination evaluation indicators, and management coordination evaluation indicators.

[0012] Furthermore, the secondary indicators corresponding to each primary indicator include: technology adaptability indicators, technology combination indicators, technology complementarity indicators, mapping sufficiency indicators, feedback effectiveness indicators, resource conservation and utilization effect indicators, environmental and water conservation effect indicators, ecological protection effect indicators, institutional matching indicators, and subject cooperation indicators.

[0013] Furthermore, the tertiary indicators corresponding to each secondary indicator include quantitative indicators and qualitative indicators.

[0014] Furthermore, the method for calculating the coupling coordination degree of green technologies throughout the entire life cycle of the railway includes: Based on the engineering data collected according to the three-level indicators, the evaluation value of each three-level indicator is calculated; the weight of each level of evaluation indicator is determined using the analytic hierarchy process. The evaluation values ​​of the secondary indicators are calculated based on the evaluation values ​​and weights of the tertiary indicators. The evaluation value of the primary indicator is calculated based on the evaluation value and weight of the secondary indicator; Based on the evaluation values ​​and weights of the primary indicators, the coupling coordination degree of the green technologies throughout the entire life cycle of the railway is calculated using a multi-dimensional coupling coordination degree evaluation model.

[0015] Furthermore, the multi-coupling coordination degree evaluation model is specifically used for: Based on the evaluation values ​​of the primary indicators, the coupling degree of green technologies throughout the entire life cycle of railways is calculated. Based on the evaluation values ​​and weights of the primary indicators, the coordination degree of green technologies throughout the railway's life cycle is calculated. Based on the coupling degree and coordination degree of green technologies throughout the entire life cycle of railways, the coupling and coordination degree of green technologies throughout the entire life cycle of railways is calculated.

[0016] Furthermore, the weights of the evaluation indicators at each level are determined using the analytic hierarchy process (AHP), specifically including: For each level of evaluation indicator, the corresponding comparison target is determined, and a judgment matrix of that level of evaluation indicator relative to the corresponding comparison target is constructed. For each level of evaluation index, the judgment matrix is ​​constructed, the weight vector is calculated and a consistency test is performed. The weight vectors of each level that pass the consistency test are used as the weights of the corresponding level of evaluation index.

[0017] In a second aspect, the present invention provides a computer-readable storage medium having a program stored thereon, which, when executed by a processor, implements the above-mentioned method for evaluating the coupling coordination degree of green technologies throughout the railway life cycle.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention provides a method for evaluating the coupling coordination degree of green technologies throughout the entire life cycle of railways. By establishing a progressive evaluation process of "analysis-evaluation-calculation," it achieves a systematic and quantitative collaborative evaluation of green technology clusters throughout their entire life cycle in the field of railway engineering. Its beneficial effects lie in breaking away from the traditional phased and fragmented evaluation model, scientifically revealing and quantifying the mutual influence and synergistic effects between technologies at different stages, thereby providing a global optimization basis for technical decisions in the early stages of a project and effectively improving the overall green benefits of railway engineering. 2.

[0019] Figure 1 This is a flowchart of the railway full life cycle green technology coupling coordination degree evaluation method in Example 1; Figure 2 This is a schematic diagram of the green technology for the entire life cycle of tunnel spoil disposal in Example 1. Detailed Implementation

[0020] The present invention will now be described in further detail with reference to specific embodiments. However, this should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0021] Unless otherwise specified, the terms "upper," "lower," "left," "right," "center," "inner," and "outer," etc., used in the description of specific embodiments of the present invention to indicate orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the product / equipment / device is usually placed during use. These terms are merely for the purpose of facilitating the description of the present invention or simplifying the description in specific embodiments, and for enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a particular device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on the present invention.

[0022] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," "parallel," and "coaxial" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, parallel, or coaxial. Slight tilt or deviation is permissible, as long as it does not affect the normal function of the relevant component. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," not that the structure must be perfectly horizontal; a slight tilt is acceptable. "Coaxial" means that two components are arranged as coaxially as possible, allowing them to move coaxially or approximately coaxially when their relative positions change. Alternatively, it can be simplified to mean that the corresponding device / component / element, when arranged in "horizontal," "vertical," "suspended," "parallel," or "coaxial" directions, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. For example, the deviation in the "coaxial" direction is controlled within 0.2-1mm, preferably within 0.2-0.5mm. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the solution of the present invention.

[0023] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0024] Furthermore, in the description of the embodiments of the present invention, "several", "more than", and "a number of" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0025] Furthermore, in the description of the technical solution of this invention, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "provided with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to connection methods commonly used in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0026] Example 1 Figure 1 The flowchart for the evaluation method of the coupling and coordination degree of green technologies throughout the entire life cycle of railways includes the following steps: S1: Based on the resource and environmental constraints of the target project, obtain green technologies suitable for the target project; It should be noted that green technology refers to a technological system that reduces consumption, pollution, and improves the environment. It encompasses fields such as energy conservation and environmental protection, clean production, clean energy, ecological protection and restoration, urban and rural green infrastructure, and ecological agriculture, involving product design, production, consumption, and recycling. This system consists of environmental knowledge, technological capabilities, and material means, and is characterized by its systematic, strategic, and dynamic development. It is closely related to high technology and includes categories such as energy technology, materials technology, and pollution control technology.

[0027] Specifically, a railway in a complex mountainous area in western China is characterized by significant topographical differences, complex geological conditions, a high proportion of bridges and tunnels, resource scarcity, and a fragile ecological environment. Therefore, green tunnel technologies such as cross-sectional structure optimization, spoil disposal and land reclamation, spoil preparation for manufactured sand, tunnel entrance greening, and wastewater treatment and reuse, as well as green bridge technologies such as high-performance concrete, prefabricated structures, steel structure painting, and green construction platforms, are applicable to the construction of this mountainous railway.

[0028] For example, regarding the prominent environmental issue of spoil disposal in tunnel sections, reducing spoil volume from the design stage and making reasonable use of spoil during construction can alleviate this problem. Therefore, adopting tunnel cross-section structure optimization technology to reduce the cross-section of parts of the tunnel during the design phase can reduce spoil volume at the source; adopting comprehensive spoil utilization technologies during the construction phase, such as spoil land reclamation and spoil preparation for manufactured sand, can turn spoil into usable resources, thereby reducing the adverse environmental impact of spoil. This does not involve the operation phase.

[0029] For example, regarding the prominent green issue of steel structure coating in bridge sections, weathering steel technology is adopted in the design phase to consider costs from a life-cycle perspective; in the construction phase, paint-free high-performance weathering steel is used, which can reduce the amount of on-site and factory painting work, improve the working environment of workers, save energy, and increase the speed of bridge construction; in the operation phase, the amount of maintenance and repair work can be greatly reduced, saving labor.

[0030] S2: Based on the preset green technology analysis model, the green technologies of the target project are processed to obtain the green technologies of the railway throughout its entire life cycle; In an optional implementation, the railway's entire life cycle includes: the design phase, the construction phase, and the operation phase. The green technologies for the railway's entire life cycle include a two-way information mapping and feedback path between the design phase and the construction phase, and between the design phase and the operation phase.

[0031] In an optional implementation, the green technology analysis model uses "demand, elements, and problems" as the classification dimensions for information transmission at each stage, and constructs and analyzes the two-way information mapping and feedback path between design and construction, and between design and operation.

[0032] Specifically, design, construction, and operation are considered as interconnected subsystems. The design subsystem maps design elements to the construction or operation subsystem, which then plans the construction or operation scheme based on the elements mapped from the design subsystem. The main elements mapped from the design subsystem to the construction subsystem include design schemes, engineering environment, technical standards, construction plans, and engineering risks. The main elements mapped from the design subsystem to the operation subsystem include design schemes, operating conditions, technical standards, and operation and maintenance recommendations.

[0033] Taking green technologies such as tunnel spoil disposal and steel bridge paint-free construction as examples, the results of using the green technology analysis model to process them are shown in Table 1.

[0034] Table 1 Examples of Green Technology Analysis Models

[0035] Furthermore, this leads to green technologies covering the entire lifecycle of railways. For example, combining tunnel cross-section structure optimization technology and waste disposal technology forms a green technology for the entire lifecycle of tunnel waste disposal (a special case of green technologies covering the entire lifecycle of railways). Similarly, combining bridge weathering steel design, construction, and maintenance technologies forms a green technology for the entire lifecycle of bridge weathering steel (a special case of green technologies covering the entire lifecycle of railways).

[0036] S3: Based on the preset green technology evaluation model, determine the evaluation indicators of the green technology throughout the entire life cycle of the railway; In an optional implementation, the preset green technology evaluation model is a multi-dimensional hierarchical evaluation model, wherein the multi-dimensional dimensions include technical dimensions, stage dimensions, functional dimensions, and management dimensions; determining the evaluation indicators for the green technology throughout the railway's life cycle specifically includes: analyzing and extracting the technical characteristics of the green technology throughout the railway's life cycle based on the multi-dimensional hierarchical evaluation model, thereby determining multiple levels of evaluation indicators, wherein the multiple levels of evaluation indicators include primary indicators, secondary indicators corresponding to each primary indicator, and tertiary indicators corresponding to each secondary indicator.

[0037] Specifically, the technical dimension is used to characterize the specific combinations of green technologies from different stages that constitute the green technology throughout the entire life cycle of the railway; the stage dimension is used to characterize the design, construction, and operation stages involved in the green technology throughout the entire life cycle of the railway; the functional dimension is used to characterize the green benefits achieved by the green technology throughout the entire life cycle of the railway, which include at least one of resource conservation and utilization, environmental protection and soil and water conservation, ecological protection, and low carbon emissions; and the management dimension is used to characterize the relevant and interoperable management system required for the implementation of the green technology throughout the entire life cycle of the railway, as well as the multiple management entities that need to cooperate.

[0038] For example, we can analyze the mapping relationship between the green technologies for the entire life cycle of tunnel spoil disposal and their functional dimensions. In terms of the stage dimension, the green technologies for the entire life cycle of tunnel spoil disposal mainly involve the design and construction stages. In terms of the functional dimension, the green technologies for the entire life cycle of tunnel spoil disposal mainly involve resource conservation and utilization, environmental protection and water conservation, and ecology. Resource conservation and utilization are mainly related to land conservation and resource utilization, environmental protection and water conservation mainly involve environmental aspects, and ecology mainly involves ecological protection and greening. Figure 2 As shown.

[0039] In an optional implementation, the primary indicators include: technical coordination evaluation indicators, phase coordination evaluation indicators, functional coordination evaluation indicators, and management coordination evaluation indicators.

[0040] It should be noted that these four primary indicators were selected to systematically and comprehensively evaluate the effectiveness and sustainability of railway green technologies throughout their entire life cycle from four mutually supportive dimensions: technological composition, process coordination, target benefits, and institutional guarantees.

[0041] In optional implementations, the secondary indicators corresponding to each primary indicator include: technology adaptability indicators, technology combination indicators, technology complementarity indicators, mapping sufficiency indicators, feedback effectiveness indicators, resource conservation and utilization effect indicators, environmental and water conservation effect indicators, ecological protection effect indicators, institutional matching indicators, and subject cooperation indicators.

[0042] In an optional implementation, the tertiary indicators corresponding to each secondary indicator include quantitative indicators and qualitative indicators.

[0043] Specifically, the evaluation indicators determined by the green technology evaluation model are shown in Table 2, with quantitative indicators accounting for more than 90%.

[0044] Table 2 Examples of Green Technology Evaluation Models

[0045] S4: Based on the evaluation indicators and the preset multi-coupling coordination degree evaluation model, calculate the coupling coordination degree of the green technology throughout the railway life cycle.

[0046] In an optional implementation, the method for calculating the coupling coordination degree of green technologies throughout the railway's life cycle includes: Based on the engineering data collected according to the three-level indicators, the evaluation value of each three-level indicator is calculated; the weight of each level of evaluation indicator is determined using the analytic hierarchy process; and the evaluation value of the two-level indicators is calculated based on the evaluation value and weight of the three-level indicators. The evaluation value of the primary indicator is calculated based on the evaluation value and weight of the secondary indicator; Based on the evaluation values ​​and weights of the primary indicators, the coupling coordination degree of the green technologies throughout the entire life cycle of the railway is calculated using a multi-dimensional coupling coordination degree evaluation model.

[0047] In an optional implementation, the multi-coupling coordination degree evaluation model is specifically used for: Based on the evaluation values ​​of the primary indicators, the coupling degree of green technologies throughout the entire life cycle of railways is calculated. Based on the evaluation values ​​and weights of the primary indicators, the coordination degree of green technologies throughout the railway's life cycle is calculated. Based on the coupling degree and coordination degree of green technologies throughout the entire life cycle of railways, the coupling and coordination degree of green technologies throughout the entire life cycle of railways is calculated.

[0048] Specifically, the multi-coupling coordination degree evaluation model is as follows:

[0049] In the formula, C For coupling degree, T For the sake of coordination, D For coupling coordination degree, U 1. U 2. U 3. U 4 represents the evaluation values ​​for technical coordination, phase coordination, functional coordination, and management coordination indicators, respectively. α , β、 γ 、 ε represents the weights of the technical coordination indicator, the phase coordination indicator, the functional coordination indicator, and the management coordination indicator. α + β+ γ + ε=1.

[0050] In an optional implementation, the weights of the evaluation indicators at each level are determined using the analytic hierarchy process (AHP), specifically including: For each level of evaluation indicator, the corresponding comparison target is determined, and a judgment matrix of that level of evaluation indicator relative to the corresponding comparison target is constructed. For each level of evaluation index, the judgment matrix is ​​constructed, the weight vector is calculated and a consistency test is performed. The weight vectors of each level that pass the consistency test are used as the weights of the corresponding level of evaluation index, where the sum of the weights of all indicators within the same level is 1.

[0051] Specifically, taking the green technology for the entire life cycle of tunnel spoil disposal as an example, the weights of each evaluation indicator are shown in Table 3: Table 3 Evaluation Indicators and Weights of Green Technologies for Tunnel Spoil Disposal Throughout its Life Cycle

[0052] The evaluation values ​​of the three-level indicators of the green technology for the entire life cycle of tunnel spoil disposal are shown in Table 4.

[0053] Table 4. Evaluation values ​​of the three-level indicators for green technologies throughout the entire life cycle of tunnel spoil disposal.

[0054] Examples illustrating the methods for determining evaluation values ​​for some third-level indicators: ① The waste reduction rate is calculated using the following formula: Waste reduction rate = Waste reduction due to tunnel cross-section optimization / Total waste volume ② The waste slag utilization rate is calculated using the following formula: Waste Utilization Rate = Total Utilized Waste / Total Waste ③ The coverage rate of waste disposal technology is calculated using the following formula: Waste disposal technology coverage rate = Number of technology requirement coverage points / Total number of technology requirement points ④ The coverage rate of the design mapping points is calculated using the following formula: Design mapping point coverage rate = Valid number of design mapping points / Total number of mapping points required by the construction plan ⑤ The effectiveness rate of problem feedback is calculated using the following formula: Problem feedback effectiveness rate = Number of valid problems / Total number of problems reported ⑥ The utilization rate of the slag yard area is calculated using the following formula:

[0055] In the formula, K czmj To improve the utilization rate of the slag yard area; V cuz This refers to the total volume of slag, including the total volume of waste slag stored in all slag storage locations; S cuz This represents the total area of ​​the slag heaps, including the area of ​​all slag heaps.

[0056] ⑦ The slag utilization rate is calculated using the following formula:

[0057] In the formula, K yz Slag utilization rate; V yz This refers to the total volume of slag used, including slag used in engineering projects and slag used locally. L This represents the total length of the line.

[0058] ⑧ The slag discharge rate is calculated using the following formula:

[0059] In the formula, Kcz Slag discharge rate; V cz This refers to the total volume of slag discharged. L This represents the total length of the line.

[0060] ⑨ The topsoil recovery rate is calculated using the following formula:

[0061] In the formula, K bthf To improve the compliance rate of slag disposal sites; S btx The area of ​​topsoil restored for the slag heap; S bty The construction of the slag heap damaged the topsoil area.

[0062] ⑩ The key point matching degree is calculated using the following formula: Key point matching degree = number of matching key points / total number of key points.

[0063] Based on the evaluation values ​​of each tertiary indicator obtained from the table above, and combined with the weight values ​​of each tertiary indicator, the evaluation values ​​of each secondary indicator can be obtained, as shown in Table 5.

[0064] Table 5 Evaluation Values ​​of Secondary Indicators for Green Technologies Throughout the Tunnel Spoil Disposal Life Cycle

[0065] Based on the evaluation values ​​of each secondary indicator obtained from the table above, and combined with the weight values ​​of the secondary indicators, the evaluation values ​​of the four primary indicators—technical coordination, phase coordination, functional coordination, and management coordination—can be calculated, which are 0.838, 0.846, 0.872, and 0.916, respectively.

[0066] Finally, based on the calculation formulas for coupling degree, coordination degree, and coupling coordination degree in the aforementioned multi-element coupling coordination degree evaluation model, the coupling degree is obtained. C The degree of coordination is 0.999. T The coupling coordination degree is 0.864. D It is 0.929.

[0067] This embodiment establishes a progressive evaluation process of "analysis-evaluation-calculation," enabling a systematic and quantitative collaborative evaluation of green technology clusters throughout their entire lifecycle in the field of railway engineering. Its beneficial effect lies in breaking away from the traditional phased and fragmented evaluation model, scientifically revealing and quantifying the mutual influence and synergistic effects between technologies at different stages.
