Description

{WATERWORKS ASSET MANAGEMENT SYSTEM}

The present invention relates to waterworks asset management. More specifically, for the asset management of waterworks in a social infrastructural infrastructure, a failure mode is used to determine the remaining life of the asset (Remaining) Service Life) and evaluating performance-based asset risk using Business Risk Exposure (hereinafter referred to as "BRE").

The rapid increase in the aging of many urban infrastructure facilities constructed and built in the past development period (for example, infrastructure facilities such as roads, water supply and sewerage, bridges, electricity and communications) It is true.

An asset management system for such infrastructure can be represented as an optimized decision process and framework during the lifecycle of acquisition, operation, maintenance, and replacement. It is not to say that this is an IT-based system, nor does it refer to a simple accounting analysis program nor does it refer to a conventional maintenance system. In other words, the asset management system for social infrastructures can be said to be a total effort of organization, manpower, and system for efficient asset management at the life cycle level as all social infrastructures are created.

In other words, the Asset Management system combines engineering, finance, economics and other means to provide risk management for material assets throughout the life of a facility and to provide the required level of service with minimal cost. To use, dispose of, and dispose of. In other words, it is necessary to define the service level required in all the processes of construction and operation of social infrastructures and to make the decision about the cost that can be taken for it by establishing a short and long term plan and optimizing it. It is to build management operation plan. In other words, asset management refers to a set of activities that manage, assess, and control cost-effectiveness in order to provide the level of service (LOS) that a customer desires.

However, in Korea, such asset management is confused with the concept of asset maintenance and system construction. Specifically, asset maintenance is performed as part of the larger context of asset management, and system building is only a tool for asset management. For example, in the domestic water supply sector, the concept of asset management for social infrastructures does not spread and is not applicable to overall facility management because it does not recognize the necessity.

The asset management system, on the other hand, is a sort of invisible system that takes into account both the human and CEO, the organization, the IT, the environment, the data and information, and the financial (asset) These systems are interconnected and involved in all decisions. For example, from the perspective of asset management, the evaluation of a facility is first evaluated as the asset value, and the value of the facility is determined based on the related data and the information of the facility.

In addition, based on these information and data, it is possible to evaluate the remaining lifetime of the facility or to evaluate the asset value. In order to do this, many detailed evaluation methods should be linked. However, in case of domestic waterworks, And the logic, which can evaluate it, has not been constructed, so that the value, life and condition of waterworks facilities are arbitrarily determined and evaluated.

Therefore, it is necessary to develop and construct a process to make more reasonable decisions on waterworks assets, to make appropriation of budget input, and to determine appropriate cost input timing. In addition, there is a need for strategic efforts to introduce and develop international standards for waterworks assets.

On the other hand, "The concept study for establishing asset management system for railway facilities (2011.10)" is presented in the proceedings of the conference.

These prior arts are described in "Conceptual Framework for Establishment of Asset Management System for Railway Facilities

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

Throughout the specification, when an element is referred to as "comprising ", it means that it can include other elements as well, without excluding other elements unless specifically stated otherwise. Also, the term "part" or the like, as described in the specification, means a unit for processing at least one function or operation, and may be implemented by hardware, software, or a combination of hardware and software.

First, referring to FIG. 1, a water service asset management object will be schematically described. 1 is a diagram illustrating a configuration of a waterworks asset management object.

1, a waterworks asset management object includes a water source 10, a water intake 20, a water purification plant 30, a water supply hydraulic pressure field 40, a reservoir 50, a general pumping station 60, a water meter 70, A water pipe is provided between the water intake pipe 20 and the water purification plant 30 and between the water purification plant 30 and the water supply water pressure field 40 and between the water supply hydraulic plant 40 and the water storage 50 Respectively, and a drain pipe is installed between the drainage compartment 50 and the general compression chamber 60.

At this time, the scope of the waterworks asset management includes waterworks asset management items from the water intake (20) to the water meter (70). Specifically, the waterworks asset management item includes items such as a pipe (here, a pipe includes a pipe line, a pipe line, a drain pipe, a water pipe and their construction / civil engineering structure), a building, a civil engineering structure, Land, and associated facilities within the site (roads, fences, etc.).

Accordingly, the waterworks asset management system according to the embodiment of the present invention performs asset management on the waterworks asset management items within the scope of the waterworks asset management described above.

2 is a diagram illustrating an asset management planning process for establishing a waterworks asset management system according to an embodiment of the present invention.

Referring to FIG. 2, the asset management planning process for constructing the waterworks asset management system according to the embodiment of the present invention first evaluates the status of the waterworks asset (S10). In other words, in order to assess the status of the waterworks assets, it is necessary to establish an asset profile (asset inventory), to set the type of service interruption, to determine the physical and economic lifespan, .

Specifically, in order to evaluate the present state of the waterworks assets, it is necessary to identify the status of the assets and register the assets. In order to do this specifically, it is necessary to construct a hierarchy of the waterworks assets and estimate the remaining life of the waterworks assets Should be. For example, information on waterworks assets is identified, a list of waterworks facilities to be managed as assets is created, and an asset informatization hierarchy diagram is constructed for them. Here, the above-mentioned asset information hierarchy diagram is configured to be linked with the use of the maintenance cost, and it should be specifically written so as to distinguish the sub-hierarchy. It is also possible to predict the remaining life of the waterworks assets by predicting the probability of failure or failure after the evaluation of the performance level and the current performance level of the waterworks facilities. Here, the remaining life of the waterworks is divided into physical life (Mortality) of the facility itself, service life dimension (LOS), capacity life dimension (Capacity), and financial efficiency dimension (Financial Efficiency) The shortest lifetime of the facility should be the life of the actual facility.

Next, the level of service (LOS) is evaluated and the target level is set (S20). That is, assess service level (LOS) and set target level by evaluating current service level, evaluating tap water asset value, setting future service level.

Specifically, in order to evaluate the service level (LOS) and set the target level, it is necessary to determine the level of the current service level (LOS) and determine the future service level (LOS) . At this time, the determination of the service level (LOS) should be preceded by a survey and review of who is the user of the infrastructure, how much is being used, and how much budget is to be secured. Such. Waterworks facilities can have different levels of service (LOS), for example, the most important being water quality, which requires management objectives for uninterrupted supply and flow rates. Here, the water yield rate is a value obtained by converting the amount of tap water produced at a water treatment plant reaching the home as a percentage, and is used as an important index of waterworks management.

Next, performance-based waterworks asset risk measurement (S30). That is, performance risk based water property risk is measured by calculating a business risk exposure (BRE) and setting the BRE rating (relative threshold). Here, the BRE will be described later.

Specifically, performance-based water asset risk measurement measures the possible accidents during the operation of waterworks assets, the business losses due to these accidents, and the expected damage caused by them. In other words, by assessing the sustainability of the operation and its risks through setting up the situation of the waterworks asset destruction, it is possible to set preventive reinforcement plans and budgets accordingly, It is possible to establish an effective operation management strategy at a small cost.

This business risk (BRE) can be expressed as the product of the Probability of Failure (PoF), the Consequence of Failure (CoF), and the Redundancy. In particular, the presence of redundancy can reduce the probability of an accident and the amount of damage caused thereby.

Failure probability (CoF) analysis required in this business risk (BRE) analysis can obtain the probability of failure (PoF) of individual waterworks assets through the process of creating a causal relationship diagram. Such a probability of failure (PoF) is related to the above-described failure mode, but since it is difficult to directly obtain it directly, methods for finding the extent of the failure can be applied. For example, in the case of finding the above-mentioned failure probability (PoF), past usage history data, expert opinion, life expectancy in product production, and similar experience can be considered.

Next, a waterworks asset management strategy is established (S40). It establishes a water supply asset management strategy by establishing appropriate maintenance and operation plans and providing an appropriate corporate image identity program (CIP) program.

Specifically, when establishing operational and maintenance strategies for waterworks assets, approaches should be made from a macro perspective and from a microscopic perspective. Here, the macro perspective refers to establishing a strategy from a portfolio perspective, a policy perspective, and a budget perspective for the entire asset, and a micro perspective refers to establishing a strategy from an occurrence event perspective and a particular asset perspective, Case-by-case decisions are made. In addition, a system should be established in which the cost input and the appropriate investment time are determined in relation to the various maintenance reinforcement decisions that occur during the life of the asset, and the cost input effect is analyzed. These water asset management strategies can take into account various cost savings, longer life spans, and alternatives that can improve service levels. In addition, this water management strategy process results in final asset value and life extension, which can be reflected in connection with the accounting / financial system by reevaluating asset value.

Next, a long-term fund plan is established (S50). In other words, a plan for future funding will be established to establish a long-term waterworks asset management plan.

Specifically, establishing a long-term funding plan means determining the Life Cycle Project Cost (ROI) over the life of the project. It will also improve performance, A dimensional maintenance strategy is planned. In establishing such a long-term funding plan, in order to operate all the assets, the appropriation cost considering the input time cost, the new generation cost, In this way, when a long-term cost plan for individual assets is established, cost estimates for all assets can be estimated, and the flow of investment cost can be analyzed and evaluated from a long-term perspective.

As will be described later, the waterworks asset management system according to the embodiment of the present invention constructs an asset management framework required by integrating user expectation, service cost, and LOS, which are the core of the asset management strategy, do.

The asset registration unit 110 collects and registers the asset information from the geographic information system (GIS) 200, for example. The waterworks asset management system 100 according to the embodiment of the present invention is implemented to operate in conjunction with the geographic information system 200. The geographic information system 200 includes a GIS integrated DB and an intranet GIS And can provide a topographical map, facility information, 3D image map, etc. related to waterworks assets. A specific description of the asset registration unit 110 will be described later with reference to FIG.

The service disruption type setting unit 120 sets the value loss of the asset according to the water service asset information, the physical fault data, and the asset minimum cost according to the physical lifetime (Mortality), the capacity level capacity (capacity), the service life level (LOS) , And financial efficiency (financial efficiency). That is, the mode of failure of waterworks assets can be divided into loss of life value, loss of capacity value, loss of service value and loss of financial efficiency.

The asset remaining life analyzing unit 130 analyzes the remaining lifetime of the waterworks asset according to the failure mode set in the service suspension type setting unit 120. [ That is, the asset remaining life analyzer 130 determines the failure mode due to the deterioration of the waterworks facilities or the members and the other routes so as to determine the timing of maintenance and reinforcement of the waterworks assets, and the scale of the required expenses. For example, the asset remaining life analyzing unit 130 may classify four types of factors such as physical life (mortality), capacitive dimension life (capacity), service provision dimension life (LOS), and financial efficiency dimensional life The shortest lifetime among the failure modes is set as the lifetime of the actual facility.

The water service level (LOS) and the goal establishment unit 140 set the service level (LOS) that the waterworks asset should provide and establish the target level in the future. At this time, there are various requirements due to the setting of the service level and the setting of the service level, and the water service level (LOS) and the goal setting unit 140 reflect the requirements to evaluate the degree of achievement of the service level do. At this time, the evaluation of the service level (LOS) should be able to be analyzed at all stages of long-term decision making, and a cost input strategy is made accordingly.

The Valuation of Waterworks (Valuation: 150) assesses the overall value of water assets held to be used in budget policy decisions and performance measurements. Also, the waterworks asset value evaluation unit 150 examines registered assets, collects asset evaluation information, identifies replacement costs for all assets, and determines and manages asset costs based on asset stratification.

The waterworks asset risk assessment unit 160 analyzes the accidents that may occur during operation of the waterworks asset management system, the business losses due to the accidents, and the estimated loss incurred by using the business risk exposure (BRE) evaluation logic do. Here, the business risk (BRE) is a method of evaluating a business risk of a company or an organization, and may be evaluated as a product of a failure probability (PoF) and a degree of damage (for example, loss amount, life damage) Will be described later with reference to Fig. 11B.

The Waterworks Asset Management Plan (AMP) Establishment Unit 170 analyzes the effects of investment strategies and costs for optimized investment in waterworks assets and makes asset investment decisions that take uncertainty into account. For example, the waterworks asset management strategy establishing unit 170 expresses the degree of improvement and change of the state of the waterworks facilities according to various maintenance strategies in connection with the cost investment risk analysis on the waterworks assets.

The Scenario Planning Section 180 systematically logicizes and manages maintenance rehabilitation plans and cost data for individual waterworks. At this time, the risk level for the individual waterworks is set and informed. Asset changes reflecting this long-term funding strategy can be fed back to the geographic information system (GIS: 200) and the management information system (MIS: 300).

The waterworks asset management system 100 according to the embodiment of the present invention determines the Remaining Service Life of the asset using the Failure Mode and uses the performance-based By assessing asset risk, water asset management can be more accurately performed.

[How to manage waterworks assets that reflect the destruction mode and business risk]

FIG. 6 is a schematic operation flowchart of a method of managing a waterworks asset according to an embodiment of the present invention.

Referring to FIG. 6, in the waterworks asset management method according to the embodiment of the present invention, first, the waterworks asset information is collected and the waterworks asset registration is established (S110). For example, asset information corresponding to the waterworks asset management item is collected and registered from the geographic information system (GIS: 200).

Next, the current water level is established based on the current capacity, the current physical lifetime status, the current service level of the asset (LOS), and the financial efficiency of the current asset (S120). In other words, the loss of value of assets according to waterworks asset information, physical breakdown data, and the lowest cost of assets can be classified into physical life (mortality), capacitive dimension capacity, service life dimension (LOS) And financial efficiency), and sets the type of water service interruption.

Next, lifetime analysis and cost analysis are performed according to the state of the waterworks asset (S 130). Specifically, the remaining lifetime of the waterworks asset is analyzed according to the set failure mode. For example, the lifetime of the waterworks asset can be estimated based on the physical life span (Mortality), the capacity life span (Capacity), the service life span The shortest lifetime among the four failure modes of the financial efficiency is set as the lifetime of the actual facility.

Next, the water service level (LOS) and the target level are established (S140). Specifically, the service level (LOS) to be provided by the waterworks asset is set and the target level is set in the future.

Next, the tap water asset value evaluation is performed (S150). Specifically, it assesses the overall value of waterworks assets that are held to be used in budget policy decisions and performance measurements. Also, the waterworks asset value evaluation unit 150 examines registered assets, collects asset evaluation information, identifies replacement costs for all assets, and determines and manages asset costs based on asset stratification.

Next, the water asset risk level (BRE) is evaluated (S160). Specifically, the business risk exposures (BRE) evaluation logic is used to analyze the possible accidents during the operation of the waterworks asset management system, the business losses due to the accidents, and the estimated losses incurred. Therefore, it is possible to identify the risk for each tap water asset by determining the failure mode of the asset and determining the risk ranking by measuring the failure probability according to each failure mode.

Next, a waterworks asset management strategy (AMP) is established (S170). Specifically, we analyze the effects of investment strategies and costs for optimized investment in waterworks assets and make asset investment decisions that take uncertainty into account.

Next, a waterway long-term fund plan (Scenario) is established (S180). Specifically, it will establish a long-term water supply plan for waterworks by managing maintenance and rehabilitation plans and cost data for individual waterworks. At this time, the risk level for the individual waterworks is set and informed. The asset changes reflecting this long-term funding strategy can be fed back to the GIS 200 and the Management Information System (MIS).

Meanwhile, FIG. 7 is a diagram for explaining asset registration in a waterworks asset management system according to an embodiment of the present invention.

As shown in FIG. 7, the waterworks asset management system according to the embodiment of the present invention includes asset collection and definition, asset name and management number assignment, asset classification, asset management data attribute building, and asset layering (Asset Register) can be established.

Specifically, asset collection and definition refers to, for example, collecting all the assets that can be recognized as current assets, and separating inventory assets and CMMS assets separately. In addition, the asset name and the management number are assigned, for example, to the asset name and management number according to the type and location of the asset, and are documented as part of the knowledge management task. In addition, asset classification refers to classification of same type and same property, for example, definition according to characteristics of property such as similar kind, function, durability and size, material, power and so on. In addition, the property building of the asset management data subdivides the data property. In addition, the asset layering collects data (evaluation, risk, residual life, etc.) necessary to support asset management decision making, To be easily distinguished from each other.

FIG. 8 is a diagram illustrating a performance curve for estimating a remaining life for analysis of a waterworks asset status according to an embodiment of the present invention.

For the analysis of the state of the waterworks according to the embodiment of the present invention, as shown in FIG. 8, a performance curve for estimating the remaining lifetime is used. For example, In order to determine the failure mode due to the failure, the degradation of the member can be expressed by the performance curve, thereby determining the timing of maintenance reinforcement and the cost scale.

9 is a view illustrating the role of the determination of the remaining life and the failure mode for the asset status analysis in the waterworks asset management system according to the embodiment of the present invention.

As shown in FIG. 9, the waterworks asset management system according to the embodiment of the present invention determines the remaining lifetime for asset status analysis using four failure modes. For example, in waterworks asset management, you can estimate the status of the waterworks asset and determine the Remaining Service Life through the asset failure mode. For example, from the viewpoint of waterworks asset management, the cause of the destruction of waterworks assets is mainly caused by the factors such as physical life (mortality), capacitive dimension, capacity service life (LOS), financial efficiency And the shortest lifetime among these is set as the lifetime of the actual facility. At this time, to understand and manage such a destruction mode, it is required to analyze the status evaluation level, capacity evaluation, and life cycle cost of all waterworks assets.

FIG. 10 is a diagram illustrating a service level (LOS) setting and a goal setting of a pump station in a waterworks asset management system according to an embodiment of the present invention.

The level of service (LOS) is determined by the criteria to be provided and the quality of service. By defining and documenting the level of service (LOS), the relationship between service level (LOS) and cost can be established, Thereby enabling better processes and risk mitigation measures. First, when the service level (LOS) at the top level is determined, a low level service level (LOS) should be determined in order to implement the service level (LOS). For example, the service level (LOS) and target of the water pump station can be set as shown in Figure 10, which indicates that the current service level is to be evaluated according to performance and reliability, and a future target level is set . This level of service (LOS) assessment and target level establishment is performed separately for each item in the waterworks asset management.

11A and 11B are diagrams for explaining the business risk (BRE) in the waterworks asset management system according to the embodiment of the present invention, respectively.

First, the risk is the core of waterworks asset management. This can be used to identify risk limits for each water line asset, prioritize limited resources and budget allocations, and establish future maintenance and improvement plans.

The waterworks asset management system according to the embodiment of the present invention uses a business risk exposure (BRE) technique as shown in FIG. 11A in order to evaluate the risk of assets and institutions, And measure the relative risk of individual assets in order to derive priorities from renewal decisions.

Specifically, the BRE is expressed as a product of three factors: a Probability of Failure (PoF), a Consequence of Failure (CoF), and a Redundancy, wherein the failure probability (PoF) It is possible to estimate the time of service failure by failure mode by providing information on the time of asset replacement by estimating the possibility of asset breakage. In addition, the result of the destruction (CoF) indicates the degree of damage to evaluate the direct or indirect effect of the destruction of the facility. Redundancy also helps to reduce overall risk exposure, for example, when there is a surplus asset to replace it in the event of the destruction of waterworks assets, the risk (risk exposure) rating may be reduced.

11B shows the probability of failure (Pof) being very low, low, moderate, quite likelihood, high, very high, and Almost Certain (Low risk), M (medium risk), S (high enough), and H (high risk) by dividing the breakdown results (CoF)

12A and 12B are diagrams illustrating the results of decision making and business risk assessment (BRE) on the failure probability and the failure result in the waterworks asset management system according to the embodiment of the present invention, respectively.

12A shows that the decision on the failure probability and the failure result in the waterworks asset management system according to the embodiment of the present invention is divided into A, B, C and D, that is, the high and low probability of failure, Indicating high and low decision making. Also, FIG. 12B shows the evaluation of the business risk (BRE) by the product of the failure probability and the failure result in the waterworks asset management system according to the embodiment of the present invention. That is, when the failure probability is divided into 1 to 3 and the failure result is divided into 1 to 3, the result of multiplying the failure probability by the failure result is displayed, and this result shows that the result becomes the business risk (BRE).
