2. Description of the Related Art There is an urgent need to develop environmentally conscious products that minimize the adverse effects on the global environment from the product life cycle, that is, from production to use and disposal. A method for quantitatively evaluating the degree of influence is a life cycle environmental impact assessment (LCA) of a product.

[0003] Specifically, the amount of mineral resources such as fossil resources of coal and petroleum, iron ore, etc. consumed before the products are manufactured, used and discarded, and the living environment of the atmosphere, water and soil. And how much harmful substances are released using the basic unit, and then use the weighting factors to quantitatively evaluate the impact on the global environment of each category such as warming and acid rain. Things.

[0004] A specific calculation and evaluation method is to calculate the environmental load in each step of manufacturing, use, and disposal of a product based on the specifications of the product and information on the materials and processing methods of the components that make up the product. Calculate various resource consumptions and emissions up to product manufacturing such as manufacturing, parts manufacturing (processing), assembly, etc. Then, based on the information of each process of the life cycle, at the time of product transport, during use and after use of products Calculate the consumption and discharge of various resources such as collection, disposal and recycling. Further, the calculated values are used to calculate the degree of environmental impact (environmental impact) for each category such as warming and acid rain using a weighting coefficient.

A typical basic system for doing this is shown in FIG. The system includes a data input unit 10 for inputting product and life cycle information, and a DB storage unit 20 for storing a database of basic units and weighting factors required for calculation.

The conventional life cycle environmental impact assessment system focuses on improving the versatility and the calculation accuracy by expanding the target product range. There were the following four disadvantages.
In other words, an actual product consists of hundreds of parts, and it takes a lot of time to enter all the information of the parts. It is very difficult to investigate the details of the manufacturing method of parts and units and grasp the raw materials and processing methods. The database of basic units and weighting factors used in the calculation differs depending on the space and method, and changes over time. (Range) occurs, and there is a limit in improving the accuracy of calculations using the range.

The present inventors have found that the four drawbacks of the above-mentioned conventional system come from the principle of LCA and can only be dealt with from the viewpoint of the system configuration. That is,
, LCA is for the LCA to evaluate the whole product, and the unit and component information that make up the LCA are indispensable. , Method) and time (past, present, future technological innovation, etc.).

3. In addition to the basic unit per material or processing method, the calculation is performed using the basic unit per product, unit, or part, or the basic unit per product, unit, or component category.

[0014] In the product life cycle environmental impact assessment system of section 4.3, the use priority of a plurality of types of basic units can be determined for each product, per product unit, per unit or component, per category of unit or component, Basic units are used in the order of raw materials and processing methods.

[0015] 5. The upper limit value and the lower limit value were also calculated using the range of the value of the database used, and the calculated value and the range (variation) of the value were also described as an output.

6. In addition to the value, a range of the value is stored as a database of the basic unit and the weight coefficient used in the calculation.

[7] The values of manufacturing, use, disposal, and the entire life cycle process are used as basic units per product, unit, or part used in the calculation.

[8] The calculated results are output separately for the values of production, use, disposal, and the entire life cycle process per product or unit or part, and the values are used as a basic unit per product, unit, or part.

In the system for evaluating the life cycle environmental impact of a product described in 9.2, the basic unit of a product or its constituent units and parts is transmitted to the other data provider via the Internet. Alternatively, the service provider calculates using the data sent from the user.

[0040]

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows an embodiment of a life cycle environmental impact assessment system utilizing the Internet according to the present invention. The difference from the conventional example shown in FIG. 9 is that the four elements of the system are divided into a plurality of users (abbreviated as a client in FIG. 1) 1 comprising a data input / transmission unit 11 and a result reception / output unit 41.
And a service provider side (abbreviated as a server in FIG. 1) 2 including an LCA calculation unit 31, a DB storage unit 21, and a data reception unit 12 and a result transmission unit 42. Have connected.

That is, the life cycle environmental impact assessment (L
The user 1 who wants to carry out CA) executes the data input transmission unit 1
When information necessary for calculation is input from the data receiving unit 1, the information is transmitted to the data receiving unit 12 of the service provider 2 via the transmitting unit 50.
The calculation unit 31 calculates the basic unit and the weight coefficient of the DB storage unit 21 and the received information, and the result is transmitted from the result transmission unit 42 to the user 1 via the transmission unit 50 again.
The result is transmitted to the reception output unit 41. In this case, a plurality of users 1 can access the service provider 2 for calculation and receive the same calculation service. Further, it is necessary to update and add the basic unit and the weighting factor used for the calculation in a timely manner. In the present invention, if the batch update is added and added in the DB storage unit 21 of the provider 2, all users 1
Has the advantage that the calculation in the new DB can be provided at the same time.

In the present invention, the DB used for the calculation on the provider side 2 includes not only the DB in the storage unit 21 but also the calculation result on the user side 1 or the information possessed through the transmission unit 50 such as the Internet. It can also be used as a basic unit. Further, information from the DB storage unit of each maker (abbreviated as a sub-server in FIG. 1) constituting a product such as a unit maker 3, a parts maker 4, and a material maker 5 is used as a unit or part Alternatively, there is an advantage that it can be used as a unit of production of a material.

Next, an embodiment of information used in the data input / transmission section 11 of the present invention will be described in detail with reference to FIG. LC
The input information required for the A calculation is roughly classified into three items related to products, parts, and life cycle processes. The present invention
Although the life cycle process information is the same as the conventional one, there is a great difference between the product information and the part information.

That is, one of the main items of the conventional product information is a product name, a model, and a capacity, but in the present invention, category information is further added. Here, the product category is
For example, video equipment, home appliances, automobiles, OA equipment, etc. are shown.
In the past, product names and models were used to identify calculation results, and capacity was used to convert results in functional units.In the present invention, these and product category names are used in calculations. The difference is that the input is used for identification. Details of these uses will be described later in detail with reference to FIG.

The second feature of the present invention is that, as part (including unit information) information, in addition to the conventional unit name, part name and material name, processing method name, weight, number, surface treatment, etc.
The point is that the manufacturer, model, capacity, and category name have been added. Here, the category indicates a storage unit (FDD, HDD) and a video unit (CRT, liquid crystal) in a unit, and a joining part (bolt, screw, rivet), a cushioning material, a painted surface or a paint, etc. in a part. This is also shown in FIG.
Although the details will be described later, in the present invention, the names and category names, models, and capacities of these components to be input are used as identification information when calculating using the basic unit of each unit or component.

Next, the evaluation result reception output unit 4 according to the present invention
An embodiment of the information used in the first embodiment will be described in detail with reference to FIG. The output items of the LCA results can be roughly classified into the inventory analysis results, which are the calculation results of consumption and emissions for each type, and the impact evaluation results, which show the global warming and acid rain load integrated for each category using the values. is there. The results of both of these are calculated for each step of the life cycle and as a whole as shown in FIG. The major difference between the present invention and the conventional output mode is that, in addition to the calculated value, the range (variation) of the value is described for each item. In this way, by specifying the uncertainty of the LCA value inherently due to the variability of the basic unit used and the weighting coefficient within a range (variation), important information for interpretation and utilization of the calculation result is provided.

In other words, a great deal of effort has conventionally been taken to improve the accuracy of the basic unit and weighting factor used as much as possible. However, as described above, there is a fundamental limit of LCA, and as a result, the calculation results are too large. The accuracy could not be improved, and the accuracy of the calculation was unclear. In the present invention, conversely, the point of recognizing uncertainty from the beginning, clearly indicating the degree of the uncertainty as a range of the result, and trying to use it as information for interpretation and utilization of the result is a big difference from the conventional idea. .

The above is a remarkable (difference can be easily confirmed) characteristic of the evaluation system according to the present invention.
Although this is a difference from the related art, the service provider side (server) including the LCA calculation unit 31, the DB storage unit 21, the data reception unit 12, and the result transmission unit 42 shown in FIG. 2 will be described in detail with reference to FIG. The input information sent from each user enters the data receiving unit 12, where the number of times of use is counted for each user.
First, the product information data 100 is read, and the product-specific D
After the B determining unit 200 determines whether the product-specific DB of the product is stored, if there is data, the product-specific basic unit DB3
The value and range are extracted from 00 and sent to the inventory analysis calculation unit 400.

On the other hand, the stored DB
If there is no DB, it is sent to the product category DB determination unit 201. If there is an existing product category DB, the value and range of the product category basic unit are extracted and sent to the inventory analysis calculation unit 400. Category D
If there is no existing DB in the B determination unit 201, the component or unit information data 11
“0” is read out and sent to the component-specific DB determination unit 202.
In addition, in order to avoid complication, "parts or the like" is described in terms of parts or units.

Therefore, if there is an existing DB, the value and range of the individual unit 302 for each component or the like are extracted, and then the data of the component or the like is sent to the determination unit 204 for determining whether or not all the data is for the component. Here, if the data of the parts etc. is not all the data yet, the parts etc. reading unit 2
Returning to step 20, the process proceeds to the inventory analysis calculation section 400 in all cases.

If there is no existing DB in the parts etc. DB judging section 202, the process proceeds to the parts etc. category DB judging section 203. Therefore, when there is an existing DB for each category, the value and range of the basic unit 303 for each category of parts and the like are extracted, and the process proceeds to the determination unit 204 for all the data for parts and the like. After extracting the value and the range of the unit 304, the process proceeds to the determination unit 204 for all the parts data.

As described above, one of the features of the present invention is that the product information 100 and the parts information 110 select five types of basic units by five routes depending on whether or not the target DB is stored. Another feature is that values and their ranges are stored as various basic units.

Inventory analysis calculation section 40 in the next step
0, various input data relating to the above-mentioned products and parts, the extracted basic units, input data 120 relating to each step of the life cycle separately read, and the value of the basic unit 305 for each life cycle process corresponding to the input data. Using the range, the consumption amount of coal oil and the like and the emission amount of CO ₂ , NOx and the like for each type are calculated.

Further, the consumption and emission values calculated by the inventory analysis calculation unit and the weighting factor 306 for each category.
The environmental load such as warming and acid rain is calculated by the impact evaluation calculation unit 500 using the value and the range.

Finally, the result 130 of the calculated inventory analysis and impact evaluation is returned to the user via the result transmitting unit 42 together with the information on the number of times of use.

The above is the description of the main part of the calculation of the life cycle environmental impact. The information on the number of times of use returned together with the calculation result is to inform the user of the service charge and to notify the user of the change of the service content in a timely manner. This is the purpose information. That is, when the conditions such as the unit price of usage and the database used for calculation are updated or added, the total number of usage counters for each user from the previous update or addition start date to the current update or addition start date is calculated. The user used before the current change is specified, and the change information is utilized only for the specified user in a timely manner.

FIG. 5 shows a specific embodiment of the basic unit 302 by parts etc. of FIG. 4 according to the present invention. This is an example of a hard disk drive (HDD) which is a unit such as a personal computer, in which a manufacturer, a model name, a capacity, a weight, and a category name are described, and a basic unit is searched and selected based on such information.

One of the features of the present invention is that, as a basic unit item, the values and ranges of resource consumption and various emissions during manufacturing per unit, and the category of each category such as global warming and acid rain in impact evaluation. That is, the values and ranges of environmental loads are described.

Another feature of the present invention is that the values and ranges of these items are displayed not only at the time of manufacture but also at the time of use or disposal, and in five items throughout the life cycle.

The present invention is not limited to these five items, and when the unit is used or discarded under the same conditions as the single unit, the values and ranges at the time of manufacture, use, and discarding are directly or corrected. Can be used. In addition, if the use or disposal method of the unit built in the product is significantly different from the single use, it is necessary to use the value and range only at the time of manufacture. Depending on the use conditions and purpose, the basic unit in FIG. Select and utilize cycle processes. FIG. 5 shows an example of a unit, but similarly, a database for each part or product and each operation such as a processing method has a similar format.

FIG. 6 shows an application of the embodiment shown in FIG. 1. The difference from FIG. 1 is that the calculation unit 31 is arranged not on the service provider 2 but on the user 1. Therefore, the transmission unit 50
Transmitted through the DB storage unit 2 of the provider side 2
Only the basic unit and the weight coefficient sent from 1 to the calculation unit 31 on the user side. The user side 1 includes a data input unit 13, a result output unit 43, a data reception unit 12, and a calculation unit 31, and the service provider side 2 includes only a DB storage unit 21 and a data transmission / reception unit 15. You. In this example,
Unlike FIG. 1, since the calculation is performed on the user side 1, the information transmitted through the transmission unit 50 is as small as only the basic unit and the weight coefficient.
And it is not necessary to send calculation conditions and results to the provider side,
Although there is an advantage that there is little danger that the information of the user is leaked to others, it is necessary that each user has a program of the calculation unit 31.

FIG. 7 shows an embodiment in which the results calculated by the present invention are used in an indirect environmental impact assessment table, which is a relevant document of the environmental management system. The environmental management system considers both the impact of the target factory (site) itself on the environment (called direct environmental impact) and the impact of the products produced at the factory on the environment outside the factory (called indirect impact). It must be grasped and evaluated, and the results need to be recorded in an evaluation table or the like. An environment management system support system supports the creation of various recording materials necessary for the process of implementing such an environment management system with a personal computer or the like.

If the results calculated by the present invention are used to create the indirect environmental impact assessment table created by this support system, accurate assessment can be realized in a short period of time. In other words, the table evaluates the impact on the environment of a product that is produced annually at a factory or the like that constructs an environmental management system before it is sold, used, and disposed of.

Specifically, the value and range of the energy consumption and the load of global warming and acid rain, which are the result of the life cycle environmental impact per product, as a result of the present invention, are added to the annual production volume of each product. By multiplying and adding, the environmental load per factory can be calculated. In this embodiment, too, the service provider provides calculation and evaluation table creation services to many users who create materials for the environmental management system via a transmission unit such as the Internet as shown in FIGS. For example, there is an advantage that an indirect environmental impact assessment table of the same level as shown in FIG. 7 can be created using common data.

[0066]

According to the present invention, the database has a basic unit for each unit or component in addition to each material or processing method as a database so that the input amount can be reduced. Both the value and range of the weighting factor are held as a database, and the database is remotely located not on the user side but on the service provider side so that the database can be added and updated with the latest information in a timely manner. By allowing the provider to exchange information, it is possible to greatly reduce the time and effort required to calculate the life cycle environmental impact assessment, and to improve the reliability and use of the assessment value.
