The present specification relates to an automation system and an automation method for managing a network of interconnected assets such as a pipeline network. More specifically, the present specification relates to an automated system and method for calculating the consequences of damage to a pipeline network such as a drinking water supply network, i.e., the degree of impact (consequence of fairule).

Over one million miles of water pipes in the United States alone have reached the end of their useful life and need to be replaced. Over the next 25 years, it will be necessary to invest at least $ 1 trillion to maintain current levels of service for a growing population. Ignoring the problem results in higher repair costs and increased service disruption.

In the United States, about 50,000 water utilities do not have the resources to replace all of them due to budget constraints. Since it is not possible to replace all expired pipes, prioritize the replacement of the worst pipes while strategically leaving the expired but healthy pipes in the future. is important.

The replacement plans created by utility companies are fairly inaccurate and often not useful. The simple model created by the utility company led to the wasteful replacement of pipes, which would have a lifespan of several more years. Over the next 25 years, this will be a waste of millions of dollars.

When creating a planned project or job to replace various segments of a pipe, utility companies may want to rely on the impact of pipe segment damage. However, calculating the degree of influence can be extremely complicated. Beyond the direct cost of plumbing repair, the impact of disruption of customer water services, and the impact on "critical" facilities near hospitals, etc., many other types of indirect There is a cost. Efforts have been made to incorporate such indirect costs by using a "weighting" mechanism for each type of additional factor. However, such efforts can form an unbalanced outlook for the overall risk distribution of the system.

It involves calculating the product with the projected cost per unit time. The estimated cost per unit time due to a service interruption can be based on the per capita cost of the service interruption and the estimated number of people affected by the service interruption due to the damage to the managed asset. Is. The estimated cost per unit time due to a transportation interruption can be based on the per capita cost of the transportation interruption and the estimated number of people affected by the transportation interruption due to damage to the managed asset. Is.

According to some embodiments, when a managed asset is in the vicinity of a critical facility, the overall impact value is associated with a service interruption and / or a traffic interruption to the critical facility. It is also possible to base it on the cost of doing so.

According to some embodiments, the interconnected and managed asset is a plumbing segment. The piping segment can be used to supply water to the consumer. According to some other embodiments, the piping segment is used to supply freshwater, drainage, recycled water, brackish water, stormwater, seawater, drinking water, steam, compressed air, oil, and natural gas. It is possible.

According to some embodiments, the consequence of failure, or impact (COF), the module allows the utility company to efficiently create impact information and map or report the impact of that information. Allows visualization in the form of. The impact module takes into account user input, prepared environmental information, and infrastructure. According to some embodiments, the COF module makes complex layered decisions regarding the relative importance of various factors or at a dollar value that does not depend on the assignment of weighting factors. Generates an impact. Therefore, it is possible to provide Utilities with a subjective and clear view of the true COF impact, based on a simple and easy-to-understand configuration.

According to some embodiments, the COF module can be described in three main groups of functions: analysis, view map, and report.

Module 1-Analysis. This module takes the user through impact analysis by allowing the user to form three basic groups of COF factors (basic COF factors, critical facilities, and other damage). In addition, the module allows the user to establish another scenario such that it is possible to select different values that the user should use to determine which COF configuration works best. Provide the structure.

Module 2-view map. The user can check both the impact of damage information and the outcome of the probability of damage on the COF map, as well as the environmental factors that contribute to the COF analysis. These factors include transportation infrastructure, critical facilities, and other things related to COF.

Module 3-Report. The report provides a clear assessment of the impact profile of the user's utility by allowing the user to select the impact category and level according to their own standards. The user can also check the distribution of the degree of influence by the piping asset information (dimensions, materials) or by the type of influence in the chart.

The following description provides a detailed description of the features provided at each stage within the COF module.

Module 1-Analysis. This analysis module contains three main groups of setups: COF scenarios, COF cost factors, and operational analysis.

Setting up a COF scenario. Before going into the details about the COF configuration, the user should define a new scenario or an existing scenario to be modified via the analysis page. The user chooses the name and description of the scenario in mind, then sets a brand new COF from scratch on a blank configuration page, copies the scenario from an existing one, or uploads the COF value from the customer's own database. Start by (ie, skip the COF analysis by uploading the customer's own COF analysis).

Correction and update of COF factors. The composition of COF factors for a blank scenario is described.

Basic COF factor . FIG. 1A-1C is an example of a graphical user interface for the schematic appearance of basic COF factors, based on some embodiments. In particular, FIG. 1A shows an interface displaying parameters for pipe repair costs. FIG. 1B shows an interface displaying parameters for service interruption costs, and FIG. 1C shows an interface displaying parameters for transport interruptions. The starting number contained in the input table shown in FIGS. 1A-1C is a "dummy" number.

Piping repair. This section of the basic COF factor covers two parts: cost and time. The customer can populate or register any one of these two parts as a starting point by clicking the button 110. This customer's choice often depends on the record keeping method chosen by the utility company. The other portion (cost or time) is then automatically registered using the pre-allocated equivalent hourly rate entered in field 112.

For example, the customer may decide to enter into the cost table based on the information shown in Table 1.

The user can then define an equivalent hourly rate (in field 112) and reasonably convert the building cost to the building period based on the rate, equipment cost, and so on. The greater the resources (labor and equipment) used for the same construction cost, the shorter the time for actual restoration. In this way, the user can determine where this hourly rate conversion seems appropriate for the utility / institution.

Assuming the user selects $ 200 per hour as the hourly rate value, the user clicks the "Autofill by hourly rate" button 114 when the "Time" table is selected in area 110. By doing so, the table can be automatically populated, that is, registered, and as a result, the table (table) 2 is obtained.

By clicking the plus and minus sign buttons 116 on the side of the table, the user can change the row to change the resolution or increment step of the pipe dimensions shown for both tables, i.e. the table. It can be added or deleted. The incremental steps are linked and reflected between these two tables.

The construction cost table gives a clear dollar value for the results from pipe repairs, but the duration of the repair is directly with the dollar value of the impact associated with two factors: service interruptions and transport interruptions: Is related.

After completing the autofill for both the Cost and Time tables, the user can modify the value in each cell without triggering another autofill operation (unless the autofill button 114 is clicked). It is possible to fine-tune each table. This means that the user "breaks" the links in these two tables through an equivalent hourly rate, and two independent repair times and costs based on his / her best engineering judgment. Allows you to create a table.

After two independent tables of repair time and cost have been created, the user may optionally click the autofill button 114 on either table to relink the information between these two tables. It is possible.

Service interruption. The service interruption "cost" can be defined as a dollar value representing the loss of a customer's water supply. In the COF modules described, the user may include (1) the number of individuals affected, (2) the amount of time affected, and (3) the dollar value per hour allotted to that effect. It is possible to define cost values for service interruptions based on factors.

In FIG. 1B, the value per hour can be entered in the field 122. The dollar amount entered defines the amount consumed by the utility company or agency to prevent a single individual customer from losing service for an hour. It has been found that this amount provides a uniform means for multiple scenarios (the number of customers who lose service for a given period of time).

The duration of the effects mentioned above can be determined by the dimensions and materials of the pipe, which are related to the construction cost of the pipe. Therefore, this information comes from the pipe repair table (shown in FIGS. 1A and tables 1 and 2).

The number of affected individuals is estimated from the dimensions of the pipe. By clicking the plus / minus sign button 126 on the side of the table, the user can add or remove rows to change the resolution or increment step of the pipe dimensions shown. be. The cells that the user should enter are highlighted with a dotted line.

The user can define an average pipe velocity, so it can be used to multiply the cross-sectional area of the pipe to obtain an average flow within a range of pipe dimensions. be. A typical velocity range is 3-5 ft / sec (fps) and can be obtained from hydraulic model results or more general knowledge based on design specifications.

Daily per capita water use can be obtained from city planning documents or operator knowledge, with a typical value of 50 gallons / day per person. In the case of average daily flow and average daily water use per person, it is possible to automatically calculate the estimated number of customers and the other two factors as shown in the following equation. It can be calculated as the effect of the value per hour based on.

Impact of interruption of all services = number of affected customers x value per hour per customer x repair
Return time Transportation interruption. Transportation interruptions can be defined as dollar values representing individuals who have access to sections of the transportation infrastructure. In the COF modules described, the user is based on (1) the number of individuals affected, (2) the length of time affected, and (3) the value per hour assigned to this effect. It is possible to define a value for transport interruption.

In FIG. 1C, the user can enter the value of the charge per hour in the field 132. The dollar amount entered defines the amount consumed by the utility company or agency to prevent a single customer from being interrupted for an hour. This quantity has been found to provide a uniform means for multiple scenarios (the number of customers delayed or suspended in transit for a given time).

As mentioned above, the time of impact can be determined by the size and material of the pipe, which is related to the construction cost of the pipe. This information comes from the pipe repair table (shown in FIGS. 1A and tables 1 and 2).

The number of affected individuals is estimated from the type of transport. A general process is illustrated in FIG. 1C. The cells that the user should enter are highlighted with a dotted line.

The user can give an estimate of the number of passengers per hour for each type of transport type. This information can be either common sense or information provided by public information from a regulatory body (eg, the Department of Transportation, BART, or the Department of Transportation). As with service interruptions, hourly values for each passenger are universally assigned to all transport types. The dollar value assigned to each pipe can be calculated by the following formula.

Impact of all transport interruptions = number of affected passengers x value per hour per passenger x repair time Critical facility. According to some examples, a "critical facility" can be defined according to a government agency such as FEMA (Federal Emergency Management Agency) in the United States. Its operation and access to and from these facilities are crucial to maintaining basic public services.

In the context of water utilities, attention should be paid to any potential damage to the water mains that can affect the critical facility. Traditionally, this has been done through various weighting mechanisms, which either overemphasize or underestimate the likelihood (likelihood) of damage to these facilities. It will be evaluated. This traditional "weighting" mechanism approach has been found to form an imbalanced view of the overall risk profile of the system.

According to some embodiments, the COF modules described herein increase their importance by considering the basic functions of these critical facilities and by assigning values that represent the importance of these facilities. On the other hand, at the same time, ensure that they are equivalent to other factors and parameters. To achieve this, if a critical facility relies on both water services and transport access in an emergency, the user may be less important than other nearby plumbing or transport. Regardless of the actual piping dimensions or transport type, these values should be overridden with a higher threshold number appropriate for those engines. In other words, even if the plumbing is small or the mode of transport is a rural road, the user will feel as if the plumbing is larger and the transport type is closer to mass transit. You have the opportunity to simply increase those values.

FIG. 2 is an example of a graphical user interface that constitutes parameters related to a critical facility, based on some embodiments. First, the user should define default values for transport and service interruption values based on the values created by the basic COF factor inputs as shown in FIGS. 1B and 1C. In FIG. 2, the user can select from the drop-down fields 210 and 212, respectively, the values per hour from the transport and service interruption rates. In the illustrated example, the user has selected a value of $ 50,000 for a highway and $ 9019 for a 12-20 inch pipe. These values are used as default hourly values to be applied to override transport and service interruption values based on the actual transport type and piping dimensions for nearby critical facilities.

The COF engine then searches for appropriate critical facilities where both access and water supply are important. By default, both access and water supply are considered important for all types of facilities. However, the user can choose to switch off one or both of these aspects as appropriate (ie, water supply may be less important to the police station).

The COF module automatically assigns higher values from the default larger piping and mass transit impact values to pipelines closer to these facilities. The transport and service interruption values are overridden by these higher values, reflecting the importance of maintaining access and / or water supply to these locations.

Using button 230, the user can add additional types of facilities by picking existing GIS information from the COF system, or upload custom GIS information to represent facilities that are important to them. Has the ability to do. For example, these facilities can include, but are not limited to, pumping facilities, processing facilities, critical customers, large industrial users, and the like.

The user also has the means to manually correct the overwrite value after turning on either transportation or service interruption for each type of facility. Default values are assigned based on the customer's initial choice of transport type or pipe dimension, but are more important compared to the default values that the facility is supplied with other types of facilities or via pipe dimensions and transport type. They can be fine-tuned if the customer decides whether they are or less important. In the example shown in FIG. 2, the user overwrites the transportation interruption value (220) for the hospital and the service interruption value (222) for the police facility. The manually changed value can be restored to the default by clicking the reset button if the interruption type is active (turn on).

Other damage. In general, other damage is an occasional event that is not predicted every time an asset fails. In other words, even if damage occurs to the associated piping segment, it is expected that the "other damage" will not occur, at least occasionally. In some examples, if the piping segment is damaged (eg, near a restaurant and the damage causes business interruption), some of the "other damage" may occur at 10%. In general, it is not expected to occur every time the associated piping segment is damaged. These are incidence rates that do not occur often and are not associated with facilities that are critical to emergency response or water supply. Other examples of these injuries include building injuries, fish kills (environmental effects) or personal injuries.

FIG. 3 is an example of a graphical user interface for configuring other damage-related parameters based on some embodiments. These ancillary conditions can be grouped into two major categories: (1) incidental conditions closely related to GIS feature types (buildings, rivers, lakes) such as building damage, and (1) 2) Ancillary conditions that are independent of any GIS feature type, such as disability or fish kills.

For other damage types that can be associated with the GIS feature type, the user must enter the impact value inferred from past or future case projection risk, along with the number of times it has occurred in the past. (If the outlook for the plan is 5 years or a 5 year LOF, the reflection must be at least 5 years for past cases). If the case has not occurred at all in the past and the user wants to add a prospect for the future, the frequency of occurrence can be set to 1.

The COF system described in this document extracts the number of damages that have occurred from the last 5 years (300 existed in this example) and divides the number of past occurrences by the total number of damages in the retrospective period. Use that information to calculate the probability that such an event will occur in the system. A representative impact value is then calculated by multiplying the value of the event by its actual probability of occurrence during the period.

The COF system described in this document then explores GIS features relevant to this type of damage that are harmful but have an overall impact or impact that does not occur each time the pipe is damaged. do. In the case of building damage, all pipes near the building are assigned an impact value equal to the following equation.

Impact value = past event value x number of past occurrences / total number of past damages within the planning period For other damage types that are independent of any GIS feature type or that are clearly not possible to relate to it. Therefore, user input for GIS features (“relevant GEO” in FIG. 3) is not required.

COF analysis operation started . After configuring the COF parameters, the user either runs the COF analysis itself or multiplies the resulting COF value by the default LOF value (typically a 5-year LOF) to achieve BRE (Business Risk Exposure). Can be calculated.

Module 2-Map . FIG. 4 is an example of a map graphical user interface for an impact module based on some embodiments. The user can do the following on the map: (1) Inspection of piping COF heatmap 410 and individual piping segments to visualize where the highest impact values are; (2) COF values including basic COF factors, critical facilities, and other damage. Inspection of piping COF details (section 412) of different constituent categories and their subcategories; (3) inspection of piping segment information including length, material, year of installation, etc .; and (4) on the map view. Change the display layer between piping information (diameter, material, year of installation), LOF information, COF information, and BRE information (menu bar 414). The symbol changes in response to the user's choice, and (5) on the map control unit (section 420), select the scenario in the view and display various GIS features related to COF calculation and analysis to be shown on the map. select.

Module 3-Report . FIGS. 5, 6A and 6B are examples of graphical user interfaces showing report views for impact modules based on some embodiments. In this report view, the user can select charts and tables generated in the COF module to identify, compare and contrast the following aspects of the system COF in the report section. That is, (1) distribution of dollar amount risk values from categories with different degrees of impact over pipe materials and dimensions; (2) distribution of impact values across different categories of COF, summary; and (3) similar to the above. The distribution of business risk exposures.

According to some embodiments, the COF modules described herein are pipes for carrying other fluids such as drainage, recycled water, steam water, storm water, seawater, steam, compressed air, oil, and natural gas. It can be applied to assets other than drinking water supply such as. According to some embodiments, the systems and methods described herein can be applied to networks such as fiber optic cables, wires, and utility poles.

Although described in some detail above for clarity, it is clear that certain changes and modifications can be made without departing from that principle. It should be noted that there are many alternative embodiments that implement the processes and equipment described in this document. Therefore, these examples are exemplary and not restrictive, and the content described herein should not be limited to the details given therein, and is within the scope of the claims.
