Description

  The present invention relates to a facility management support system for water treatment facilities such as water purification facilities and sewage treatment facilities, and in particular, to realize a budget using a life cycle cost (hereinafter referred to as LCC (Life Cycle Cost)). The present invention relates to an equipment management support system for water treatment facilities for supporting the development of medium- to long-term plans for maintenance inspections and updates.

  Many of the water and sewerage treatment facilities were constructed during the period of high economic growth, and the time for renewing the equipment is approaching. In addition, renewal of equipment is an important measure for securing an emergency lifeline, such as improving earthquake resistance.

  However, the budget that can be used for maintenance and renewal of equipment is decreasing due to the decrease in water revenues due to the reduction of tax revenue, national budget, and demand. For this reason, proper operation and management of assets with a view to the entire system of water supply and sewerage is required.

  Asset management includes measures not only for renewing after a predetermined period of use, but also for ensuring the functions of equipment by performing appropriate maintenance inspections, maintenance, and life extension measures.

  A method of setting the maintenance frequency and contents of equipment in various plants has been proposed. In the conventional technique described in [Patent Document 1], a device shipped to a predetermined shipping destination is used as a population, and the reliability within the population is determined based on equipment maintenance information such as device identification information and failure occurrence time information. We provide a device that performs sex analysis and evaluates the maintenance time of equipment.

  In infrastructure management, an asset management system for bridges and roads has been proposed. The conventional technique described in [Patent Document 2] provides a system that supports LCC evaluation and medium- to long-term planning using a measurement data and a deterioration prediction formula for bridges.

  [Patent Document 3] also includes a memory storing data indicating the state of the water facility, and data indicating the state of the water facility before and after the failure signal is generated when the water facility generates a failure signal. And a water supply business support system that retrieves and displays failure history data from memory. Then, in the equipment life cycle evaluation, information for each equipment is collected, the equipment renewal costs are compared with the benefits of renewal, the break-even point of profit and loss is defined as the equipment life cycle, and the cost is minimized. It is described that the update is planned for each device and each facility.

  The conventional technology described in [Patent Document 1] can set the maintenance time for the set type of equipment or parts, and improve the reliability as a product. However, in tap water quality management, when it is desired to preferentially maintain equipment that has a large effect on water quality and water volume, the method described in [Patent Document 1] cannot prioritize to determine the equipment to be maintained. There is.

  On the other hand, the conventional technique described in [Patent Document 2] takes a method of obtaining deterioration of a bridge material by a deterioration evaluation formula. However, there are a wide variety of facilities and equipment related to water supply and sewerage, such as concrete structures, metal pipes, electric motors, electrical products, and water quality measuring instruments, and these loss of function and failure are not necessarily limited to those accompanying deterioration of materials. Therefore, the deterioration evaluation formula using the use environment as a parameter shown in [Patent Document 2] is not sufficient when water supply and sewerage facilities are targeted.

  In addition, the system described in [Patent Document 3] can evaluate the life cycle in which a failure occurs when a failure occurs in a water supply facility, but gives priority to equipment that has a large impact on water quality and water volume. Is not considered.

  An object of the present invention is to provide an equipment management support system capable of implementing soundness evaluation, LCC evaluation, and planning taking into account the characteristics of these facilities in order to support the establishment of facility management plans for water and sewer facilities That is.

  In order to achieve the above object, the present invention provides an equipment database for storing information on equipment and equipment, a maintenance and inspection database for storing results of maintenance and inspection of equipment and equipment, a process database for storing process data, and the soundness of equipment and equipment.

  By adopting such a configuration, it is possible to build a maintenance / inspection / update scenario according to the degree of soundness required for the equipment and to properly manage the LCC.

  In addition, the operational conditions of equipment that reflect parameters that should be considered in the water supply and sewage systems, such as water quality management target values to be achieved in the future and the amount of water supply or sewage inflow based on projections of population fluctuations in the target area of water supply or sewage inflow And soundness evaluation and / or LCC are calculated based on this.

  It also reflects the installation environment, such as the corrosive environment unique to water and sewage facilities, in the soundness assessment.

  By adopting such a configuration, it is possible to calculate a more accurate LCC and improve the accuracy of the maintenance management plan for medium- and long-term equipment.

  In planning, the priority items of equipment / equipment, failure occurrence frequency, failure occurrence risk, maintenance / renewal costs, the number of devices, and districts should be prioritized, and a scenario corresponding to this should be selected. To do. With such a configuration, an equipment management plan suitable for the budget can be easily formulated.

  According to the present invention, a wide range of equipment such as machinery, electrical equipment, measuring instruments, civil engineering structures, piping, etc. included in water supply and sewerage facilities are targeted for maintenance inspection and renewal plans necessary for their maintenance. Can be formulated so as to satisfy the LCC conditions in the medium to long term at an appropriate time for each equipment.

  The memory 31 stores programs of a data collection unit 40, a soundness evaluation unit 41, an LCC calculation unit 41, and a plan selection unit 42. The CPU 30 executes this program and performs various calculations.

  At this time, the network IF 32 performs information communication with the terminal 2 connected to the network 3 and the equipment of the water supply facility 100, and the information transmitted from the network 3 and the memory 31 are stored in the various databases described above. Information generated by executing the program group and information set and input from the terminal 2 and the data input / output terminal 33 are stored.

  The equipment DB 34 stores information on equipment equipment of the water supply facility 100. Examples of the equipment information include a sedimentation basin (civil engineering structure), a pump, a valve, and piping. These equipments are managed in a plurality of hierarchies, for example, four hierarchies of site-facilities large classification-medium classification-small classification.

On the other hand, as a scenario on the income side, the budget amount estimated from the water charge etc. in each fiscal year is stored.

  In the evaluation result DB 38, results evaluated by the soundness degree evaluation unit 41, the LCC calculation unit 42, and the plan formulation unit 43 are stored.

  In the management system of the present embodiment, initial setting, soundness evaluation, LCC calculation, and planning are performed.

  FIG. 3 is a diagram showing a screen for performing initial settings for performing soundness evaluation and LCC calculation.

  In the example shown in FIG. 3, there are a site button 51, a large classification button 52, a middle classification button 53, and a name button 54 as target selections, which can be clicked and displayed in a pull-down manner. Further, a selection button 55 from the map and a display button 56 for data are provided so that selection can be made from the map and data can be displayed.

  Maintenance, maintenance column 57, failure effect column 58, and soundness evaluation method column 59 are provided. For maintenance and maintenance, the method, frequency, cost, and LCC implementation time resetting method can be input. The contents, scale, cost, and remarks can be entered in the case of failure. In the soundness evaluation method, an evaluation method, an evaluation formula, parameters, and remarks can be input.

  Look at the screen and make the following settings for each equipment. According to the maintenance / maintenance column 57, (1) the maintenance management method and frequency of each facility device, (2) the cost associated with each maintenance management or update, and (3) the maintenance management and update execution timing used for the LCC evaluation And (4) Content and cost of social impact when failure occurs, and evaluation method of soundness level, according to the method of resetting the implementation time according to the soundness level (recruitment check column) and the effect field 58 at the time of failure In column 59, (5) Soundness evaluation method, evaluation formula, and parameters used in the evaluation are set.

As a method for evaluating the soundness, for example, there are the following methods.
(1) In the evaluation by the deterioration evaluation formula, the degree of deterioration of the material is obtained by a mathematical formula (y = f (x1, x2,..., Xn)), and the soundness level is evaluated. It can be applied to soundness assessment when deterioration over time can be predicted for civil engineering structures and consumables made of concrete. The degree of soundness can be treated not only as a continuous value obtained from the calculation but also as a rank by dividing the calculated value.
(2) For the evaluation using ○ / × of the check items, check items related to the soundness of the target equipment are provided, ○ and × are scored as 5 points and 1 point, respectively, and the soundness is evaluated by the average value. To do. At this time, a weight can be set for the check item to reflect the importance of the check item. This method can also be applied to cases where quantitative evaluation is difficult, and can be applied to general equipment related to water and sewage.

Further, as a simpler method using the check item ◯ / ×, there is a method of setting the ranks of ◯ and × in advance. When there are a plurality of check items, it is possible to adopt the minimum rank or the average value.
(3) Evaluation using the useful life evaluates the soundness by comparing the useful life of each equipment and equipment that is defined in the regulations and the actual use years. The soundness level can be set by a monotonous decrease with age or a curve having an extreme value. As an example of the latter, there is a bathtub curve (curve in which failure occurrence increases in the early and late stages), which is generally known as a pattern in which failure occurs.
(4) The evaluation using the previous maintenance and the maintenance time represents the soundness as a function of time with reference to the time when the maintenance is performed. In setting the function, the level of soundness level recovered by maintenance and maintenance, allowable soundness level, average failure interval, etc. are taken into consideration.

  The soundness level evaluation unit 40 performs the process shown in FIG. In S401, an equipment device in which an evaluation method for soundness evaluation is set is selected and imported from the equipment DB 34. In S402, the health evaluation method for equipment and the maintenance inspection results and process data used for soundness calculation taken in from the maintenance check DB 35, process DB 36, and scenario DB 37 are fetched.

  In S403, the soundness level regarding each facility device is evaluated according to the soundness level evaluation method. At this time, the evaluation of the deterioration formula is converted into soundness. In S404, the soundness evaluation result is output to the terminal 2 and the evaluation result DB 38, and the soundness evaluation result in the past predetermined period is captured.

  FIG. 5 shows a screen example for soundness evaluation. The site button 51, the large classification button 52, the middle classification button 53, and the name button 54 are operated, and the user selects the target range of processing in S401 shown in FIG. All combo boxes have (all) choices. When (All) is selected, all the equipment included in the hierarchy selected at the upper level is taken in as an evaluation target. In order to facilitate the user's selection operation, it is also possible to display a map screen by using a selection button 55 from the map and directly select a corresponding facility or device from the map.

  By pressing the data display button 56, the processing from S402 is performed, the measurement result of the parameter used for calculating the soundness level is displayed in the related measurement result column 61, the evaluation index of soundness level, the soundness level is displayed in the evaluation result 62 The calculation result of is displayed. Also, a health trend is displayed in the health record 63. At this time, when the soundness level can be predicted from the deterioration evaluation formula, an expected curve is displayed together.

  FIG. 6 shows a processing flow of the LCC evaluation unit 41. In S601, the target equipment is fetched from the equipment DB 34. In step S602, the maintenance inspection implementation status, maintenance scenario, and current soundness level of the corresponding equipment are fetched from the maintenance inspection DB 35, scenario DB 37, and evaluation result DB 38, respectively.

  In step S603, the maintenance management time according to the scenario is reset using the actually performed maintenance and inspection work and soundness as parameters. In other words, there are cases in which the time required to perform maintenance work in the future may shift due to unexpected failures or unplanned maintenance work, so the time of execution will be updated in accordance with the preventive maintenance frequency set in the scenario. To do.

  If there is a change in the maintenance management time, the information is output to the terminal 2. In S604, an LCC is calculated using the reset maintenance management time. In S605, the result is output to the terminal 2 and the evaluation result DB 38.

  FIG. 7 shows an example of a screen for LCC evaluation. Similar to the case of soundness evaluation, the processing target range in S601 shown in FIG. 6 is selected. In addition, a department in charge of management of the equipment can be specified by a department button 64 in charge. The LCC display is performed by operating the LCC display button 66, and the LCC evaluation is performed by selecting the equipment associated with the designated department.

  The evaluation result 67 is plotted in the form of a change in LCC with respect to time, and in the column 68 of the list, No., target device, implementation time, implementation content, cost for each event, cost of the department in charge for each event for which expenses have occurred. Display a list. Further, when displaying the integrated value of the maintenance cost related to the lower-level equipment, the numerical value can be displayed by the “+” button.

  In FIG. 7, a symbol indicating the time corresponding to No. in the list is displayed. Further, the filter execution button 72 is used to filter the display items in the list, and the LCC accumulated by the filtered items is displayed in the figure. For example, by collecting and displaying the data in units of water purification plants, water distribution districts, and departments in charge, the user can partially assist in the examination of an optimal plan.

  FIG. 8 shows a processing flow in the plan selection unit 42, and FIG. 9 shows an example of a plan selection screen. In S801, the site button 51, the large classification button 52, the middle classification button 53, and the name button 54 shown in FIG. 9 are operated to select the equipment that is the object of the LCC evaluation from the equipment DB 34. In addition, a department in charge of management of the equipment can be specified by a department button 64 in charge. Further, a selection button 55 from the map and a display button 56 for data are provided so that selection can be made from the map and data can be displayed.

  In S802, the LCC calculation result, the maintenance management scenario and the budget amount are fetched from the scenario DB 37 and the evaluation result DB 38, and the evaluation result 75 plotted with respect to time is output to the terminal 2 and displayed. In step S803, the LCC is compared with the budget. If the budget is exceeded, a confirmation 76 for executing scenario re-editing is displayed on the terminal 2 in step S804.

  In step S805, the scenario DB 37 related to the selected equipment is displayed as the scenario setting field 77 in FIG. At this time, the display order may be the order of numbers set in the equipment, but the past failure history is searched from the maintenance DB 35, the average failure interval (MTBF: Mean Time Between Fail) of the equipment is calculated, and MTBF Can be displayed in the order of equipment that is longer than the period of regular maintenance described in the scenario. After the scenario change by the user, the LCC is evaluated again by the LCC calculation function 41 in the reset scenario.

  The scenario set when the scenario re-editing becomes unnecessary is output to the terminal 2 and the evaluation result DB 38 as a medium- to long-term plan.

  The configuration of the present embodiment is basically the same as the configuration of the first embodiment, but in this embodiment, the accuracy of soundness is further improved by adding evaluation parameters peculiar to water supply to the soundness evaluation function 40. It is something to be made.

  The parameters to be added are water quality management target values, facility modifications, population changes in each water supply area (including forecasts), and installation environment of facility equipment. The water quality management target value and population change data are stored in the scenario DB 37, and the installation environment of the equipment is stored in the equipment DB 34, respectively. These data are acquired by selecting an evaluation target of the soundness evaluation unit 40 in S401 and acquiring data in S402.

  The procedure to reflect the water quality management target value and facility modification in the soundness assessment is shown. Water quality management target values include water quality standard values and set values set independently by water utilities. In order to satisfy these set values, it is necessary to appropriately adjust the operation in the water purification process. For example, when the management target value of the water quality item removed by coagulation sedimentation is set to a lower value, it is usually necessary to increase the injection rate of the coagulant. The effect is that not only chemical injection equipment such as chemical injection pumps, but also the amount of purified water sludge increases, which increases the load on the wastewater treatment facility.

  On the other hand, as a modification of the equipment, for example, an inclined pipe is introduced, whereby the injection rate of the flocculant can be reduced. As a result, contrary to strengthening the water quality management target value, the load on the equipment will be reduced.

  Therefore, in the evaluation of the soundness level, first, the influence of the setting change of the management target value on the operation of the device such as the chemical injection is evaluated. For example, in addition to empirical setting methods such as extrapolation of actual measurement data and preset values, the chemical injection amount can be obtained by an injection rate equation or simulation. Change can be set.

  The changed operation condition is substituted into the deterioration evaluation formula, or is reflected in the evaluation of the soundness level by multiplying the soundness level as a weight. A corresponding scenario is selected according to the obtained soundness level, and the LCC is evaluated.

  Next, a method for reflecting the installation environment in the soundness will be described. Water supply equipment may be installed in an environment where moisture, water droplets, or the like exist, and pipes are basically buried, so that the corrosive environment of the soil at the burial point differs. Therefore, a corrosive environment index is added as information related to piping stored in the facility DB 34. In addition to using this index as a parameter of the degradation evaluation formula, the influence can be taken into account by directly multiplying the soundness as a weight.

  Since the water supply business is an infrastructure that plays an important role of supplying water, maintenance is performed so that the breakdown of equipment is extremely small. For this reason, it is often difficult to obtain an average failure occurrence interval (MTBF), which is one of indexes for soundness evaluation, or accuracy is low. It is a suboptimal measure to obtain the MTBF by collecting the same type of devices, but only an average value can be obtained. By performing weighting in consideration of the installation environment in this way, it is possible to expect an improvement in the accuracy of the soundness evaluation of individual devices.

  Explain how to reflect population change in soundness. In the evaluation of the system according to the present embodiment, the population dynamics of the water supply district affects the evaluation of the water supply amount and the water charge revenue.

  Changes in the amount of water supply affect the load on pumps and motors for water supply and drainage, as well as the operating time of chemical injection equipment used for water purification and disinfection. On the other hand, although water bill revenue depends on the billing system, under normal settings, revenue decreases as usage decreases. This decrease in revenue will result in a decrease in the budget that can be used for maintenance inspections and facility replacement, and it must be taken into consideration in the final medium- to long-term planning.

  In particular, the former is directly linked to the scenario. As shown in Fig. 10, using the mapping function and population fluctuation data for each district, the change in the amount of water handled by each district and each device is obtained and confirmed on the map. It can be so. In future cost calculation, using these values can improve the LCC accuracy of individual devices.

  The map display screen shown in FIG. 10 selects and displays the installation environment, population, population change rate, and water supply change shown in the second embodiment. The target selection screen 80 displays districts, sites, major classifications, and the like, and the map screen 81 displays a map corresponding to the target selection field. A target area or the like can be selected from the target selection screen 80. Below the target selection screen 80, a soundness button 82, an LCC button 83, an environment button 84, a population button 85, an artificial change rate button 86, and a water supply change button 87 are displayed. By operating these buttons, The installation environment, population, population change rate, and water supply change can be selected and displayed.

  The configuration of the present embodiment is basically the same as that of the first embodiment, but the plan formulation unit 42 formulates a maintenance inspection / update plan that satisfies the budget and takes into consideration the priority items set by the user.

  Specifically, the flow is shown in FIG. In S111, priority items are set from the terminal 2, and in S112, the system takes in priority items and information on devices, scenarios, and costs necessary for LCC calculation and medium- to long-term plan formulation from each DB. The priority items include the importance of the equipment, the frequency of occurrence of failures (results), the risk calculated from these, the number of equipment, the cost of each maintenance check, renewal, and the district where the equipment is installed.

  In S113, the LCC is calculated according to the initial scenario, the cost is tabulated in S114, and then compared with the budget in S115. If the budget is not satisfied, the scenario is changed in S116.

  To change the scenario, the a value that satisfies Equation 1 is obtained and set as a new scenario.

  Here, Ctotal is the budget, Ci is the cost required for the maintenance inspection of the equipment i, a is the number of the equipment that performs the maintenance inspection according to the initial scenario when arranged in order of priority items, and f (x) is the value of the priority item A factor for changing the frequency of maintenance inspection with a function, x is the value of the index selected as the priority item. The function system of f (x) is not particularly limited, but a simple example is a linear function.

  The scenario change is output to the terminal 2, the evaluation result DB 38, and the scenario DB 37. As another method for adapting the LCC to the budget, there is a method of selecting a plurality of priority items. In this method, the inspection execution frequency of each device is changed using a function with x1, x2,... As parameters instead of f (x).

  According to each embodiment, it is possible to set a maintenance management scenario of equipment and equipment so that an LCC satisfies a budget in a water and sewage facility, and it is possible to operate a good business entity.
