[First Embodiment]
An environmental load reduction support apparatus according to the first embodiment of the present invention is shown in FIG.

  In FIG. 1, the environmental load reduction support device 1 inputs object data (for example, object information including name, classification, standard, model number, and specification) related to selection of an object (for example, a product, a unit, or a part).

  Here, the input device 10 corresponds to a design information input unit 19 described later. The computing device 20 corresponds to a component reuse environmental load calculation unit 14, a material recycling environmental load calculation unit 15, a resource recycling environmental load calculation unit 16, and an object selection unit 17 which will be described later. The storage device 30 corresponds to a component information storage unit 11, a component reuse coefficient storage unit 12, and a material recycling coefficient storage unit 13 which will be described later. The output device 40 corresponds to a selection object display unit 18 described later.

  When the environmental load reduction support apparatus 1 is configured using a personal computer, the input device 10 corresponds to, for example, a scanner, a pointing device, and a keyboard. Here, instead of the input device 10, an input device (for example, a server) on a network (not shown) and an interface for connecting to the network may be provided. The computing device 20 corresponds to a memory such as a CPU, ROM, and RAM, for example. The storage device 30 corresponds to an external storage device using, for example, a hard disk, a flexible disk, or an optical disk as a recording medium. The output device 40 corresponds to a printing device such as a laser printer or an inkjet printer, and a display device such as a liquid crystal display or a CRT display.

  Next, the functional configuration of the environmental load reduction support apparatus 1 according to the present embodiment is shown in FIG.

  In FIG. 2, the component information storage unit 11 includes component names, component classifications, component numbers, dimensions, tolerances, component weights (including the weight of each material if it is composed of multiple materials), specifications, and purchases. First, parts supplier, model number, material, processing method, material-containing substance information (whether or not containing hazardous chemical substances, weight or proportion if present, whether or not containing controlled substances, if present, weight or proportion, prohibited In addition to the presence or absence of substances, the weight or ratio if present), cost, whether parts can be reused as part reuse data, parts reuse rate, material recycling data, recycling rate, and recycling method Material recycling is a recycled material content ratio that indicates the proportion of recycled material if the component material is recycled material or virgin material. The rate is stored.

  The component reuse coefficient storage unit 12 stores a plurality of component reuse coefficients calculated based on the LCA. Since the environmental load calculated by LCA differs depending on characteristics, weight, etc., a plurality of component reuse coefficients are stored according to characteristics, etc. The component reuse coefficient storage unit 12 also stores component reuse coefficient classification conditions, and is used to select a component reuse coefficient having a classification condition corresponding to the component information stored in the component information storage unit 11. . Here, as the classification condition, for example, the copying speed of a copying machine may be used. Note that the number of classification conditions is not limited to one and may be plural. Further, the component reuse coefficient storage unit 12 stores a plurality of component reuse coefficients corresponding to each classification condition and environmental load item, and may be tabulated.

  The material recycling coefficient storage unit 13 stores a material recycling coefficient calculated based on LCA. Since the environmental load calculated by LCA differs depending on the material, characteristics, etc., a plurality of material recycling coefficients are stored. The material recycling coefficient storage unit 13 also stores the material recycling coefficient classification conditions, and is used to select the material recycling coefficient of the classification conditions corresponding to the part information stored in the part information storage unit 11. . Here, as the classification condition, for example, the copying speed of a copying machine may be used. Note that the number of classification conditions is not limited to one and may be plural. Furthermore, the material recycling coefficient storage unit 13 stores a plurality of material recycling coefficients corresponding to each classification condition and environmental load item, and may be tabulated.

  The component reuse environmental load calculation unit 14 calculates the environmental load related to component reuse from the selected component reuse coefficient and the component reuse rate stored in the component information storage unit 11. Here, the part reuse rate is the ratio of the reuse part weight to the product weight, and is obtained by, for example, the equation (1).

  Instead of using the weight ratio as the component reuse rate, the reuse component weight may be used. However, it is necessary to match the reuse component coefficient and dimension. Further, here, when a part is an object, the part reuse rate indicates whether or not the part can be reused, and is 100% if the part can be reused and 0% if the part cannot be reused.

Further, the data indicating the environmental load related to component reuse calculated by the component reuse environmental load calculation unit 14 is an environmental load value related to component reuse, for example, energy consumption, resource usage, CO ₂ emission, NOx emission, SOx. It is a value such as the amount of emissions or a converted value such as points, and this is used as the environmental load index value for component reuse. These values are determined by the component reuse factor.

  The material recycling environmental load calculation unit 15 calculates an environmental load related to material recycling from the selected material recycling coefficient and the material recycling rate stored in the part information storage unit 11. Here, the material recycling rate is the ratio of the recycled material weight to the product weight, and is obtained by, for example, the formula (2).

  Instead of using the weight ratio as the material recycling rate, the total weight may be used, or the weight ratio for each material may be used. Specifically, it may be the ratio of the recycled plastic weight in the product to the total plastic weight in the product. This is obtained, for example, by equation (3).

  Furthermore, instead of using the weight ratio as the material recycling rate, the weight of recycled material for each material may be used. However, it is necessary to match the material recycling factor and dimension. Moreover, although Formula (2) and Formula (3) calculate the material recycling rate about a product, even if it applies to components, it is formed similarly not only in this.

Further, the data indicating the environmental load related to material recycling calculated by the material recycling environmental load calculating unit 15 is an environmental load value related to material recycling, for example, energy consumption, resource usage, CO ₂ emission, NOx emission, SOx. This is a value such as the amount of emissions or a converted value such as points, which is used as an environmental load index value for material recycling. These are determined by the material recycling factor.

The resource recycling environmental load calculation unit 16 adds the environmental load index value related to component reuse calculated by the component reuse environmental load calculation unit 14 and the environmental load index value related to material recycling calculated by the material recycling environmental load calculation unit 15. Thus, an environmental load index value related to resource circulation is calculated. This is, for example, values such as energy consumption, resource usage, CO ₂ emissions, NOx emissions, SOx emissions, etc., or converted values such as points. By doing so, simple addition becomes possible.

  The object selection unit 17 selects a recommended object (hereinafter also referred to as “recommended object”) from the environmental load index value calculated by the resource circulation environmental load calculation unit 16. This object may be any of a part, a unit, and a product. For example, by adding the environmental load index values of the component parts of the unit or product, the environmental load index value of the object can be obtained as will be described later. One or a plurality of recommended objects may be selected here, and the recommended objects may be ranked.

  The selection target object display unit 18 displays the recommended target object, the environmental load index value of the target object, the necessary conditions regarding the standard / specification, and the target object information. Here, it is preferable to make the discrimination easy by marking the recommended object, displaying the recommended objects in the recommended order, or coloring the display column or characters of the recommended objects.

  Here, the component reuse coefficient is a numerical value calculated based on the LCA, and is classified and stored in the component reuse coefficient storage unit 12. Also, the component reuse coefficient selected by the component reuse environmental load calculation unit 14 is not limited to one, and a plurality of component reuse coefficients may be set.

  The material recycling coefficient is a numerical value calculated based on the LCA, and is classified and stored in the material recycling coefficient storage unit 13. Further, the material recycling coefficient selected by the component reuse environmental load calculation unit 14 is not limited to one, and a plurality of material recycling coefficients may be set.

  Here, FIG. 3 is a table in which the copying speed of the copying machine is set as the classification condition, and the component reuse coefficient and the material recycling coefficient related to the copying machine parts group are tabulated corresponding to each environmental load item. In FIG. 3, the coefficient tables 101 to 103 are stored in a storage device 30 corresponding to the component reuse coefficient storage unit 12 and the material recycling coefficient storage unit 13. For example, when product data of a low-speed copying machine is input from the design information input unit 19 (corresponding to a case where the copying speed as the classification condition is low), the component reuse environment load calculation unit 14 displays the low-speed copying machine shown in FIG. The component reuse coefficient of the reuse component group corresponding to the corresponding reuse component in the product data is acquired from the machine coefficient table 101. In addition, the material recycling environmental load calculation unit 15 acquires the material recycling coefficient of the recycled material group corresponding to the corresponding material in the product data from the coefficient table 101.

  Furthermore, an example of a method for calculating a component reuse coefficient and a material recycling coefficient will be shown. First, based on the well-known LCA, inventory analysis of life cycle (including manufacturing, logistics, use, disposal / recycling) is performed for each of new products, new parts reuse products, and material recycling products with new parts of the same product. Total calculated values (inventory analysis values) for each category. In this way, a total value (hereinafter referred to as “LCA value”) is obtained for each of the new product, the component reuse product, and the material recycled product. Next, by using each LCA value, the environmental load reduction rate of the component reuse product with respect to the new product and the environmental load reduction rate of the material recycling product with respect to the new product are obtained, and the ratio of the environmental load reduction rates of both is obtained. Using this ratio, a weighting coefficient for parts reuse and material recycling (corresponding to parts reuse coefficient and material recycling coefficient) is calculated.

  With respect to the environmental load reduction support apparatus 1 configured as described above, a support procedure (support procedure after login) when selecting an object during product design will be described with reference to FIG. Here, the environmental load reduction support apparatus 1 manages information with a registered user ID and password when a designer or the like logs in or calls as necessary during product design.

  In step S101, the design information input unit 19 inputs product design data. For example, when the designer operates an operation key (not shown) of the input device 10, an input screen showing a predetermined input item is displayed on the output device 40, and product design is performed for each input item by the designer's key operation. Data may be input. Or you may make it input product design data from the input device on a network via a connection interface (not shown).

  Here, the product design information includes a product name, a product classification, an identification code, a product standard, a specification, and the like. If there is a design target module, it is also entered. The product design information may be registered in advance or may be input each time. Alternatively, only product information may be retrieved and presented without inputting product design information.

  In step S102, the design information input unit 19 inputs a part information search condition. For example, a designer may set a necessary part specification in product design by operating an operation key (not shown) of the input device 10 and input this as a part information search condition. Alternatively, the component information search condition may be input from an input device on the network via a connection interface (not shown).

  Here, one or more necessary conditions are input from the component classification, component name, dimension, tolerance, weight, material, and other specifications as the component information search condition. Since the part information search condition is an AND expression, the number of corresponding parts decreases if there are many inputs.

  In step S103, the part reuse environmental load calculation unit 14 and the material recycling environmental load calculation unit 13 correspond to the part information (part reuse rate, material recycling) from the part information storage unit 11 according to the part information search condition input in step S102. (Including rate). In this search, if the relevant part information is equal to or less than a predetermined number or does not exist, priority is given to the part information search condition, and part information of similar specifications is searched according to it. For the priority order, the degree of specification requirement may be input as a numerical value or a ratio.

  In step S104, the component reuse environmental load calculation unit 14 and the material recycling environmental load calculation unit 13 receive the component reuse coefficient and the component reuse coefficient corresponding to the component information acquired in step S103 from the component reuse coefficient storage unit 12 and the material recycling coefficient storage unit 13, respectively. Select a material recycling factor.

  In step S105, the component reuse environmental load calculation unit 14 calculates an environmental load index value related to component reuse from the component reuse coefficient selected in step S104 and the component reuse rate acquired in step S103. In addition, the material recycling environmental load calculation unit 15 calculates an environmental load index value related to material recycling from the material recycling coefficient selected in step S104 and the material recycling rate acquired in step S103.

  In step S106, the resource circulation environmental load calculation unit 16 calculates an environmental load index value related to resource circulation from the environmental load index value related to component reuse and the environmental load index value related to material recycling calculated in step S105.

  Here, the environmental load index value related to resource circulation is related to resource circulation and parts constituent materials, or the environmental load index of an object calculated from the environmental load index value related to resource circulation and the environmental load index values related to component constituent materials. An index value may be used, and an environmental load index value necessary for the purpose of the design is used. When the object is a unit, the environmental load index value of the unit is calculated by adding the environmental load index values of the parts constituting the unit.

  In step S107, the object selection unit 17 selects a recommended object (for example, a part or a unit) from the environmental load index value related to resource circulation calculated in step S106. Here, the recommended object may be one or a plurality of objects, or may be ranked.

  In step S108, the selection target display unit 18 displays the recommended target selected in step S107, the environmental load index value of the target target, the requirements regarding the standard / specification of the target target, the supplier, and the component supplier. The component information such as the model number, material, processing method, and cost is displayed on the screen of the output device 40. Here, the recommended object may be marked, displayed in the recommended order (shown in FIG. 5), or colored in the display column or characters, etc., for easy identification.

  Through the support procedure described above, the designer satisfies the standards and specifications by referring to the information on the recommended object displayed on the output device 40 and the environmental load index value related to resource circulation and the component information acquired in step S103. In addition, environmentally friendly objects can be selected.

For material-containing substance information, calculate the environmental impact factor for each material from the degree of environmental impact for each hazardous chemical substance, controlled substance, and prohibited substance. Since the environmental load coefficient for each material is different for each material, all of them may be stored, or materials with different environmental load coefficients for each material within a predetermined range are classified, and the average value or representative value is classified for each material. You may unify it as another environmental load coefficient. The target material here is a new material, and the environmental load coefficient for each material is a coefficient in the new material.
