Description

  The present invention relates to a technology for assisting in setting a recycling target for predicting and reducing the environmental load given by a product, clarifying the relationship between the recycling target and the environmental load, and setting the target for the total amount of products and businesses. In order to realize the environmental load, it is possible to support the appropriate setting of the recycling target value.

  Accepting the input of the target period for evaluating the environmental load or eco-efficiency as an issue to be solved, assessing, predicting, planning (target setting), and managing the environmental impact of the total amount of objects on the environment. Accessed the load database that stores the environmental load of each object in correspondence with the life stage of the object, and acquired the environmental load according to the life stage of each of the multiple objects in the target period. Japanese Patent Application Laid-Open No. 2004-157746 describes a technique for solving the problem by calculating the actual value of environmental load or environmental efficiency based on the total amount of objects in the target period based on the environmental load.

In the above publication, the environmental impact of the total amount of multiple objects on the environment in any one of the target periods in the past or future is evaluated, predicted, set, and managed to achieve the target. A system that can do is shown.
And in the above conventional technology, when setting the environmental load of the target product (new product etc.), the improvement effect data from the previous machine (increase of recycled parts, reduction of power consumption, easy maintenance management, etc.) The amount of carbon dioxide generation that accompanies the product is subtracted from the actual environmental load value of the previous machine, and the environmental load amount (predicted amount 2) of the target product is obtained. When the predicted amount 2 is larger than the environmental load amount (predicted amount 1) calculated based on the parameter that determines the environmental load of each life stage, the improvement effect is corrected so as to be reduced. Here, the environmental load amount is a value per product, and the improvement effect amount can be set as a target so as to be the target environmental load amount per product. However, it is not known whether the environmental load target setting method as described above will fit the total product amount and the environmental load amount of the entire business within the target. For example, it is not possible to determine which is better by manufacturing and selling a large number of products with a small environmental load and by manufacturing and selling a small number of products with a large environmental load. When considering the global environment, the amount of environmental load to be considered is the total amount of environmental load in products and businesses.

[Problems of the prior art]
The reduction of environmental burden in business activities of companies is not only related to the design stage, but also related to the point at which products are collected and recycled. Companies are making efforts to reduce their environmental impact by setting recycling targets. However, the recycling target is an item for managing the business such as the number of products reused and the parts reused mass, and its achievement is evaluated. Originally, with the goal of reducing the environmental load (for example, exhaust CO ₂ ) by a predetermined amount, It is important whether the goal has been achieved. However, with CO ₂ reduction, we do not know what kind of business activities are necessary for that purpose. In other words, there is a problem in that it is not known whether or not the recycling target can be properly set because the recycling target that the company can manage is different from the environmental load that affects the environment. Furthermore, the amount of environmental load that should be managed is the total amount of products and businesses.
In addition, there are many goals for reducing the environmental impact of a company's business activities over the life cycle, but they are usually designed to maximize their effectiveness by different personnel. . In particular, in recycling, there is a limit on the amount of input (collected number) because there is no collected product, so if there are multiple types of recycling, the effect will be maximized for each type, and the total will exceed the input amount. There is a possibility that it will become the number of recycling. Therefore, it is necessary to evaluate and change the target so that a plurality of targets are established simultaneously.

Next, embodiments will be described with reference to the drawings.
A DB (database), which is a component of the present invention, is a collection of data configured on a database management system (DBMS). For example, a relational database management system (SQL Server of Microsoft Corporation) operating on a personal computer (PC). (TM) etc.). The data structure is based on a table format and can have a plurality of tables in the DB. A plurality of DBs may exist in one PC, or a DB may exist in each of a plurality of PCs. Data recording and extraction in the DB can be performed by a query language such as SQL (Structured Query Language) supported by the DBMS. The SQL may be operated on the PC in which the DB exists, or the SQL may be sent from another PC to the PC in which the DB exists to receive the result of the extracted data.

[Each component database]
Hereinafter, each DB of the constituent elements will be described.
The recycling target DB includes one or more tables in which planned values and actual values of recycling-related business target values are recorded. The business target value is the value of items related to the business plan such as the weight of reused parts and the number of resource recycling products sold. As for each value, as shown in FIG. 1, the recycling target item is recorded separately for each product and model for each year.
There may be a table summarizing the recycling target values for each fiscal year. In the case of Fig. 1, the total value of RA1 'and RA2' (Fig. 1 (c)) of the model targets for reused parts mass is shown as RA in FY2004. '(Fig. 1 (a)).

Further, the actual value recorded in the recycling target DB also has a model-specific table in the same manner as the planned value.
The planned value for each model further records the fluctuation range of the planned value. This range shows the range when the target value is changed by the simulation processing of the present invention. For example, as shown in FIG. 1 (c), “0.1, 0.1” in the 2004 fiscal year range indicates that it can vary within a range of 10% negative and positive with RA1 ′ as the center. . Further, “0, 0” indicates that it cannot be changed (the description of other parts in the figure is omitted).
In addition, as shown in FIG. 1D, there is a table in which the part mass reused from one unit and the number of parts used for parts reuse are recorded. The weight percentage of component reuse can be considered instead of the component mass of component reuse. The part reuse mass is obtained by multiplying the part reuse quantity per part by the number of parts reused (RA1 ′ = RA1′_1 × RA1′_2). The value RA ′ of the reuse part mass is a value obtained by stacking these.
The target value may be classified by product, model, year, as well as affiliated company and business site. These target values are determined and recorded in advance outside the system.
In the embodiment, when the products A models A and B are collected, the parts are extracted and recycled as reuse parts (part reuse), and the main body is recycled and recycled as a resource recycling product (product reuse). And will be explained mainly.

The environmental load target DB is a DB that manages items that are environmental loads such as CO ₂ and energy amount as target values. In this embodiment, the environmental load is evaluated by EPS (Environmental Priority. Strategies for Product Design), which is a technique for weighting the influences of CO ₂ , energy, environmental pollutants and the like and performing an integrated evaluation. The unit is ELU.
FIG. 2 shows a structural example of the environmental load target DB. The target is recorded for each management range and year. For example, when the management is performed for each group company and the total is set as the environmental load of the entire group, the table format is for each company and each year as shown in FIG.

  The business goal DB is a database for managing business goals in a company, and records the number of units sold, actual values, etc., as shown in FIG. For example, the product A model A has a sales plan from the fiscal year 2004 to the fiscal year 2006, and records BA 'units, BE' units, and BI units, respectively. As actual results, BA ″ units and BE ″ units are recorded in 2004 and 2005, respectively. In FIG. 3 only, the sales plan and the actual result of 0 year are recorded as 0, and the year in which the actual results are not aggregated is shown as blank.

The collection prediction DB is a DB in which a value predicted for collection of used products is stored. The items recorded in the recovery prediction DB include the prediction of the number of recovered products, the prediction of the recovery rate, etc. In this example, as shown in FIG. 4, the recovery rate defined as a percentage of the total number of units sold for each model and year And The total number of units sold can be multiplied by this value to predict the number recovered. For example, according to Fig. 3 (b), the total sales volume of product A, model A, is the plan for FY2004 and FY2005, with BA "units and BE" units. Since BI units are used and BA ″ + BE ″ + BI units, the estimated number of recovered units in 2006 is (BA ″ + BE ″ + BI) × CH ′ / 100 units.
Further, if the actual value is also recorded in the recovery prediction DB, more accurate recovery prediction is possible (see FIG. 4B).

The material flow rate DB is a record of the predicted quantity of logistics for each product or model for each year and each life cycle stage. As an example, as shown in FIG. 5, it can be seen that the number of products A in model A is estimated to be equivalent to one DA in the procurement stage in FY2004.
In addition, the collection and recycling stage records data for each type of recycling. As shown in FIG. 5B, the result of predicting the material flow rate for each model is recorded by dividing into three types of recycling: parts reuse, product reuse, and recycling.

As shown in FIG. 6, the environmental load unit amount DB records the environmental load per unit amount of a product or model for each life cycle stage. The unit amount is per vehicle or per kilogram. The environmental load may be indicated only by the total result ELU, or details such as input resources, input energy, and emission substances during the calculation may be added depending on the purpose.
Furthermore, the environmental load for each model and each life cycle stage is detailed in accordance with the range managed by the environmental load target DB. 6B and 6C, the ELU for each affiliated company is recorded.

Furthermore, since the unit amount and environmental load vary greatly depending on the type of recycling at the collection / recycling stage, more detailed data is recorded.
In FIG. 6C, recycling of the collected product is divided into three parts reuse, product reuse, and resource recycling. Parts reuse means extracting parts to be reused from the product and recycling the rest. Product reuse is the reproduction and reuse of a product as it is. Recycling here is material recycling, thermal recycling, etc. other than parts reuse and product reuse. The resource recycling product in the recycling target DB corresponds to product reuse. Each environmental load unit amount is recorded. FIG. 6C shows a detailed table for each model and each company.

Data recorded in the environmental load DB can be created from data collected when performing LCA (Life Cycle Assessment) of a product. In addition, the value of the model in the planning / designing stage where LCA cannot be performed without a track record may be recorded as a target value that is equivalent or reduced by several percent in view of the previous model.
Information such as specifications related to products is recorded in the product information DB. The mass for each model described in the present embodiment is recorded as shown in FIG.
The level of detail of items managed in the above DB, for example, “by product or model”, “every year / month”, “life cycle stage category”, etc., details of recycling target values and environmental load target values You can decide according to the degree.

[Processing procedure]
Next, the processing procedure will be described below.
FIG. 9 is a flowchart showing main processes, and the target setting for fiscal 2006 is described as an example.

[Step 1]
In step 1, the user selects an item for which a recycling target is to be determined based on the output indicated by the output device, and inputs the year to be set (see FIG. 10). The system retrieves the data of the selected item from the recycle target DB and records it in a primary storage area (not shown). After this recording, the system outputs the input screen of step 2 (FIG. 11).

[Step 2]
In step 2, the user inputs a target value of environmental load to be achieved in the set fiscal year (see FIG. 11). The system stores the input environmental load target value in the environmental load target DB.

[Step 3]
Step 3 is a step of an object flow rate predicting unit that predicts an object flow rate in a target year using values of a recycling target DB, a business target DB, a recovery prediction DB, an object flow rate DB, and a product information DB. In this example, as shown in FIG. 5, the predicted flow rate is divided for each model, every year, and every life cycle stage. A forecast example of product A model A in FY2006 is as follows:
The number of units procured is the planned sales unit BI.
The production quantity is the sales planned quantity BI.
The distribution / sales volume is the planned sales volume BI.

  The number of units used / maintained indicates the number in the market, and is obtained by subtracting the total number of units collected from the total unit sales. However, since the market volume during FY2006 fluctuates, it is necessary to take an appropriate representative value. For example, there is a method of averaging the market number at the end of 2005 and the market number at the end of 2006. An example of calculation is shown below. The cumulative number of units sold at the end of 2005 is BA "+ BE" as shown in Fig. 3 (b), and the total number of collected units is CA "+ CE" as shown in Fig. 4 (b). The market number is (BA ″ + BE ″) − (CA ″ + CE ″). The cumulative sales volume at the end of 2006 is BA ″ + BE ″ + BI as shown in FIGS. 3 (a) and 3 (b). The cumulative recovery volume is calculated using the recovery rate shown in FIG. 4 (a). Since CA ″ + CE ″ + {(BA ″ + BE ″ + BI) × CH ′ / 100}, the market quantity is (BA ″ + BE ″ + BI) − [CA ″ + CE ″ + { (BA ″ + BE ″ + BI) × CH ′ / 100}]. Therefore, the number of used / maintained units (market units) is the average of the above two market units.

The number of recovered / recycled units is (BA ″ + BE ″ + BI) × CH ′ / 100 using the recovery rate shown in FIG.
Furthermore, the collection / recycling stage can predict the flow rate of goods for each type of recycling. Before explaining the calculation, FIG. 8 shows the relationship between the collected amount and the flow rate of each recycling type. Each square area in FIG. 8 represents the number of products and the size of mass. The collected products are classified into recycling type parts reuse, product reuse, and recycling. In parts reuse, parts to be reused are extracted and the rest are recycled (recycling). Therefore, the hatched square portion in FIG. 8 is the flow rate of each recycling type.

[Calculation procedure]
Next, the calculation procedure for each recycling type will be described.
How the collected products are recycled can be understood from the values recorded in the recycling target DB (see FIG. 1). That is, since the component reuse plan for product A model A in FY2006 is RK1 (Kg) from the recycling target DB, the component reuse is RK1 (Kg). The equivalent number is RK1_2 (unit). Since product reuse is RM1 (unit) from the recycling target DB, product reuse is RM1 (unit).
By the way, this value is input in advance by each person in charge. Therefore, if each person in charge sets a value to achieve the maximum effect, the total number of parts reused and the number of products reused may exceed the number recovered. That is, a plurality of target values do not hold simultaneously. Since recycling can be done with collected machinery, the plan needs to be evaluated and changed.
In the present embodiment, it is evaluated whether or not the number of parts reused and the number of products reused are smaller than the number collected. If the number is small, it is judged that the planned number can be procured. This is expressed as follows.
RK1_2 + RM1 <(BA ″ + BE ″ + BI) × CH ′ / 100

If it cannot be determined that it can be procured, prioritize the target numbers that have a smaller reduction effect per recovery machine, and reduce the number to match. The reduction effect per collection machine can be understood from the recycling target DB and the environmental load unit amount DB. In the case of the embodiment, it is as follows.
For parts reuse: UA51a × RK1_1
For product reuse: UA52a
If the size of the above two cases is compared and if the case of parts reuse is small, the collection machine for parts reuse is as follows.
(BA ″ + BE ″ + BI) × CH ′ / 100−RM1
On the other hand, when the number of parts reused and the number of products reused are less than the number of recovered products, the respective reuse target values are adopted.

The amount of resources recycled is the remaining amount obtained by subtracting parts reuse and product reuse from the collected amount. If the number of parts reused and product reused remains the target, the recovered mass is DA5 x SA (Kg) from the product flow rate DB (see Fig. 5) and the product information DB (see Fig. 7). The mass of reuse is RM1 × SA (Kg). Therefore, the resource recycling is DA5 × SA-RK1-RM1 × SA (Kg).
As described above, even if multiple targets are not established at the same time, the target value can be corrected, and the flow rate by stage in the target year can be set to an appropriate value, and the obtained value is recorded in the prediction table of the physical flow rate DB. Is done.
When it is not possible to determine that procurement is possible and the target flow rate is changed, the changed value is also recorded in the corresponding recycling target DB.

[Step 4]
Step 4 is an environmental load prediction unit that predicts the environmental load in the target year from the physical flow rate DB and the environmental load unit amount DB and records it in the primary storage area. As shown in FIG. 6 (a), the environmental load unit amount DB records the environmental load amount per unit amount in the life cycle stage. The life cycle of the physical flow rate DB shown in FIG. 5 (a) is recorded there. Multiplying the amount of material flow at the stage gives the total environmental load at each life cycle stage.
For example, according to the environmental load unit amount DB, the environmental load in procurement per product A model A can be obtained by summing up the procurement examples in the table. Here, UA1 (ELU) is assumed. Since the estimated number of procurement in 2006 is DC1 (unit), it is predicted that an environmental load of UA1 × DC1 (ELU) will occur. In the collection / recycling stage, the environmental impact is similarly predicted for each type of recycling. In this example, the environmental load for each company is targeted in step 2, so a more detailed table of environmental load unit amount DB for each company (FIGS. 6B and 6C) is used for each company. All lifecycle stages of all models can be calculated and summed. The obtained environmental load value for each company is recorded in the primary storage area.

[Step 5]
In step 5, it is determined whether the environmental load value predicted in step 4 satisfies the target value recorded in the environmental load target DB by comparing the magnitude. For example, when the environmental load of the entire group is targeted, if the environmental load predicted in step 5 is the same as or smaller than the EK (ELU) stored in the environmental load target DB (FIG. 2A), it is used for prediction. The target can be achieved under the conditions.
If the goal can be achieved, go to Step 6.
If the goal cannot be achieved, go to step 7.

[Step 6]
In step 6, the predicted environmental load value is overwritten in the environmental load target DB. In this case, the value is equal to or better than the value recorded in step 2.

[Step 7]
In step 7, the recycling target value is changed to approach the set environmental load target value. For example, the reuse value per product A model A in the planned value “part reuse” table (Figure 1 (d)) in the recycling target DB is “RK1_1” (Kg) for the 2006 target. Although the environmental load is predicted, it is calculated how much the environmental load changes by changing this value. The fluctuation range is recorded in the fluctuation range in 2006, and in this example, it means ± 10% centered on “RK1_1”. If the number is reused, it is ± 10% of “RK1_2”. Similarly, the other recycle targets are read from the DB and the fluctuation range is changed. The way to change is “upper limit value”, “lower limit value”, “upper / lower limit value”, “divide the upper / lower limit value into steps”, etc., and the environmental load increases or decreases as the target value increases In this case, if the relationship is known in advance, the “upper limit value” or the “lower limit value” may be used, and if the relationship is unknown, the “upper limit value” may be used. If the environmental load does not necessarily increase or decrease due to other conditions, the “between upper and lower limit values” is divided into, for example, 10 steps and calculated using each value.

All combinations of target values to be changed may be implemented to obtain those with a low environmental load. If there are a large number of items to be changed, optimization methods such as general linear programming and branch and bound methods may be used. Alternatively, it may be determined that the environmental load is in the vicinity. A particularly suitable example for obtaining an optimal solution is that the total environmental load is an objective function, the number of parts reused and the number of products reused is less than the number recovered, and the fluctuation range of the recycling target value is recorded in the recycling target value DB. It is better to find a solution that minimizes the value of the objective function by linear programming, with the range being within the range.
As shown in FIG. 12, the result is recorded in the primary storage area in association with the predicted value of the environmental target to be set, and the set of the result of the changed recycling target value. The output of the results is output from FIG. 12 as a list in ascending order of the environmental load, and in consideration of the overall optimum of the environmental load, in this example, a list in the order of the environmental load of the entire group may be considered.

When the list is output, an input screen for selecting which list is displayed to the user, and one of them is selected by the user, and the recycling target value and the environmental load value are the recycling target DB and the environmental load target DB, respectively. To be recorded.
In order for users to decide recycling targets, it is necessary to consider not only the environmental impact, but also costs, laws and regulations, trends of other companies, etc. It is efficient if we consider from small goals. When adopting all of them, it is efficient to consider from the recycling target group whose environmental impact of the entire group is small in the total recycling target.
Through the above processing, this system can efficiently support the target setting by outputting the recycling target value and the environmental load target value that can achieve the environmental load target if the recycling target is achieved.
