It should be noted that this restriction condition can also be made indispensable when it is necessary to exchange the product attribute.

  Expression (4) is a constraint condition for preventing the quantity of products used instead of being larger than the quantity of products constituting the system product. This restriction condition may not be required depending on a specific processing method.

  Equation (5) shows that the cost required when introducing an optimized target system product is the rate of increase or decrease in the cost required by the customer compared to the introduction cost of the target system product before optimization. It is a constraint condition to satisfy. This restriction condition does not need to be satisfied if the customer does not request it.

  Equation (6) is a constraint condition for the environmental load of the optimized target system product to satisfy the environmental load increase / decrease rate required by the customer compared to the environmental load of the reference system product as a reference for comparison. is there.

  In the present embodiment, the environmental load of the optimized target system product is compared with the environmental load of the reference system product as a reference for comparison.

For example, It is also possible to compare the environmental load of the optimized target system product with the environmental load of the target system product before optimization to satisfy the increase or decrease in the environmental load required by the customer. .

  In addition, there is no brush that satisfies the constraint condition expressed by equation (6) when the customer does not request it.

  Equation (7) is the introduction cost of the calculation system product that is the target for calculating the cost by the objective function, the cost when using the calculation system product, the cost when collecting the calculation system product, and the recycling of the calculation system product The sum of the cost of time and the cost calculated from the environmental load obtained by subtracting the environmental load of the target system product to be optimized from the environmental load of the calculated system product is calculated.

  Here, the cost calculated by subtracting the environmental load of the target system product to be optimized from the environmental load of the calculated system product is obtained by subtracting the environmental load of the target system product to be optimized from the environmental load of the calculated system product. Calculated by multiplying the environmental load by a predetermined environmental load cost conversion factor. The greater the environmental load obtained by subtracting the environmental load of the system product to be optimized from the environmental load of the calculated system product, the greater the cost. It is supposed to be.

The environmental load cost conversion coefficient is a coefficient for converting the environmental load (CO ₂ emission amount here) as a cost, and here, the cost in the life cycle of the system product is expressed as the life of the system product. Although the value calculated by dividing the environmental load (CO ₂ emission amount) by ₂ in the cycle is used, it is not limited to such a mode.

Equation (8) is the introduction cost of the calculation system product that is the target for calculating the cost by the objective function, the cost when using the calculation system product, the cost when collecting the calculation system product, and the recycling of the calculation system product. The cost calculated from the sum of the cost and the environmental load of the calculated system product minus the environmental load of the target system product to be optimized, and the delivery date from the planned shipment date of the products that make up the calculated system product An added value of the cost calculated from the number of days after subtracting the day is calculated.

  Here, the cost calculated from the number of days obtained by subtracting the delivery date from the planned delivery date of the products constituting the calculation system product is set to a smaller value as the delivery date is earlier than the expected delivery date.

  The delivery date cost conversion coefficient is a value determined in advance to convert the number of days as a cost.

  Here, as will be described later, when the delivery date condition is not designated, the product configuration that minimizes the value calculated by the objective function of equation (7) is set as the optimization target system product.

  On the other hand, when the delivery date condition is specified, the product configuration that minimizes the value calculated by the objective function of equation (8) is set as the optimized system product.

  And the product evaluation part 124 produces | generates the evaluation total table 163 as shown, for example in FIG. 26 (schematic diagram of the evaluation total table 163), and stores the calculated variables E1-E4 and C1-C4.

  As shown in the figure, the evaluation summary table 163 includes an evaluation classification row 163a, a summary unit row 163b, a shipping row 163d, a procurement row 163e, a transportation row 163f, an installation row 163g, and a startup row 163h. (Introduction customer) line 163i, use (introduction destination customer) line 163p, maintenance line 163w, collection line 163x, and recycling line 163y.

Stores “0”.

  Thus, step S30 in FIG. 25 is completed.

  Next, the product evaluation unit 124 performs a process of calculating the environmental load and cost in the life cycle of the system product and storing them in the evaluation aggregation table 163 (S31).

  First, the product evaluation unit 124 newly generates two records in the evaluation totaling table 163, the character string “environmental load” is displayed in the evaluation classification row 163a of one record, and “system” is displayed in the totaling unit row 163b. Of the other record, the “cost” character string is stored in the evaluation classification row 163a of the other record, and the “system” character string is stored in the aggregation unit row 163b.

  First, in the specific record in which the character string “environment” or “999” is stored in the evaluation classification field of the life cycle condition table 162 shown in FIG. 24, the product evaluation unit 124 stores the evaluation item field 162c of the specific record. The conversion coefficient field of the record in which the stored information matches the information stored in the evaluation item field 113c of the environmental load conversion table 113, and the character string “environment” is stored in the evaluation classification field 113b. The conversion coefficient stored in 113d is specified, and the environmental load is calculated by multiplying the specified conversion coefficient by the numerical value stored in the numerical value field 162e of the specific record in the life cycle condition table 162.

  Then, the product evaluation unit 124 associates the calculated environmental load with the information “environmental load” in the evaluation classification row 163a in the evaluation aggregation table 163 in association with the information stored in the block field 162a of the life cycle condition table 162. The column is stored, and stored in the record in which the character string “system” is stored in the total unit row 163b.

  If there are a plurality of environmental loads calculated from the same information stored in the block field 162a of the life cycle condition table 162, the added value is stored in the corresponding record.

  Further, the product evaluation unit 124, in the specific record in which the character string “cost” or “999” is stored in the evaluation classification field of the life cycle condition table 162 shown in FIG. 24, the evaluation item field 162c of the specific record. The conversion coefficient field of the record in which the stored information matches the information stored in the evaluation item field 113c of the environmental load conversion table 113, and the character string “cost” is stored in the evaluation classification field 113b. The conversion coefficient stored in 113d is specified, and the cost is calculated by multiplying the specified conversion coefficient by the numerical value stored in the numerical value field 162e of the specific record in the life cycle condition table 162.

  Then, the product evaluation unit 124 associates the calculated environmental load with the information stored in the block field 162a of the life cycle condition table 162 in the evaluation classification row 163a of the character string “cost” in the evaluation aggregation table 163. Is stored in a record in which the character string “system” is stored in the total unit row 163b.

  When there are a plurality of costs calculated from the same information stored in the block field 162a of the life cycle condition table 162, the added value is stored in the corresponding record. However, when the information stored in the block field 162a is “use”, only the same in the division field 162d is added, and the environmental load calculated from the record in which “0” is stored in the division field 162d and The cost is stored in the usage (introduction customer) row 163i, and the environmental load and cost calculated from the record stored as “1” in the classification field 162d are stored in the usage (introduction customer) row 163p.

  When the information stored in the block field 162a is “use”, the environmental load and cost calculated as described above are multiplied by the years of use of the system product input in step S10 in FIG. Stores a value.

  Furthermore, the numerical value stored in the record of “introduction cost” in which the information stored in the block field 162a is “design development” and the information stored in the evaluation item field 162c is not used for cost calculation.

  Next, the product evaluation unit 124 newly generates two records in the evaluation totaling table 163, the character string “environmental load” is displayed in the evaluation classification row 163a of one record, and “total” is displayed in the totaling unit row 163b. Is stored in the evaluation classification row 163a of the other record, and the “total” character string is stored in the aggregation unit row 163b.

  Then, the product evaluation unit 124 stores a record in which the character string “environmental load” is stored in the evaluation classification line 163a, the character string “component” is stored in the aggregation unit line 163b, and the evaluation classification line 163a. The evaluation classification line is obtained by adding the value stored in each of the lines 163d to 163y of the character string of “environmental load” and the record storing the “system” character string in the total unit line 163b. The character string “environmental load” is stored in 163a, and the character string “total” is stored in the total unit row 163b.

  Further, the product evaluation unit 124 stores a record in which a character string “cost” is stored in the evaluation classification row 163a, a character string “component” is stored in the aggregation unit row 163b, and a character string “component” is stored in the evaluation classification row 163a. The value stored in each of the rows 163d to 163y of the character string “cost” and the record storing the “system” character string in the total unit row 163b is added to the evaluation classification row 163a. Is stored in the corresponding row of the record in which the character string “cost” and the character string “total” in the total unit row 163b are stored.

  With the above processing, the product evaluation unit 124 ends the product evaluation processing S31 of FIG.

  Next, the evaluation result output process in step S12 of FIG. 9 will be described.

  First, the evaluation result output unit 125 stores, in the evaluation product name field 164a, the name of the system product to be evaluated that has been input in step S20 of FIG. 10, and ID that is identification information uniquely assigned to each system product is ID. The system product usage year field 164c stored in the field 164b and received in step S20 of FIG. 10 is stored in the product usage year field 164c, and information specifying the date and time when the system product was evaluated is evaluated date field. By storing in 164d, an evaluated product table 164 as shown in FIG. 27 is generated and stored in the evaluation result storage area 118. The ID and the date and time when the evaluation is performed are determined in advance by the evaluation result output unit 125 and acquired according to the law.

  Next, the evaluation result output unit 125 adds the ID field to the product configuration table 160 (see FIG. 11) stored in the temporary information storage area 117 as shown in FIG. 28 (schematic diagram of the evaluated product configuration table 165). An evaluated product configuration table 165 to which 165f has been added is generated. The ID field 165f of the evaluated product configuration table 165 stores an ID uniquely assigned to each system product when generating the evaluated product table 164, and includes a product classification field 165a, a product name field 165b, and a model number field. Information stored in the corresponding field of the product configuration table 160 is stored in each of the field 165c, the quantity field 165d, and the procurement division field 165e.

  Then, the evaluation result output unit 125 stores the evaluated product configuration table 165 generated in this way in the evaluation result storage area 118.

  Further, the evaluation result output unit 125 stores the ID in the life cycle condition table 162 (see FIG. 24) stored in the temporary information storage area 117 as shown in FIG. 29 (schematic diagram of the evaluated life cycle condition table 166). An evaluated life cycle condition table 166 with the added field 166f is generated. The ID uniquely assigned to each system product when generating the evaluated product table 164 is stored in the ID field 166f of the evaluated life cycle condition table 166, and the block field 166a, the evaluation classification field 166b, and the evaluation item are stored. Information stored in the corresponding field of the life cycle condition table 166 is stored in each of the field 166c, the division field 166d, and the numerical value field 166e.

  Then, the evaluation result output unit 125 stores the evaluated life cycle condition table 166 generated in this way in the evaluation result storage area 118.

  Furthermore, the evaluation result output unit 125 adds the ID row 167z to the evaluation summary table 163 (see FIG. 26) stored in the temporary information storage area 117 as shown in FIG. 30 (schematic diagram of the evaluated evaluation summary table 167). The evaluated evaluation total table 167 to which is added is generated. The ID uniquely assigned to each system product when the evaluated product table 164 is generated is stored in the ID row 167z of the evaluated evaluation totaling table 167, and the evaluation classification line 167a, the totaling unit line 167b, and the shipping line are stored. 167d, procurement line 167e, transportation line 167f, installation line 167g, startup line 167h, use (introduction customer) line 167i, use (introduction customer) line 167p, maintenance line 167w, collection line 167x and recycling line 167y include: Information stored in the corresponding row of the evaluation aggregation table 163 is stored.

  Then, the evaluation result output unit 125 stores the evaluated evaluation aggregation table 167 generated in this way in the evaluation result storage area 118.

  Here, in the present embodiment, the evaluation result storage area 118 includes a reference system that is a system product that serves as a reference for comparing a target system product that is a system product proposed to a customer and the target system product. Assume that a table related to the evaluation results of products is stored in the evaluation result storage area 118. The reference system product is preferably a system product currently used by a customer, for example, but an old model of the target system product can also be used.

  Next, the optimization condition input process in step S13 in FIG. 9 will be described.

  First, the optimization condition input receiving unit 126 receives an input of optimization conditions requested by the customer via the input unit 130.

  Here, in the present embodiment, as optimization conditions requested by the customer, an input of an index that the customer has the highest priority, a condition related to cost, and a condition related to environmental load is received.

  For example, in the present embodiment, the optimization condition input reception screen 181 shown in FIG. 31 (schematic diagram of the optimization condition input reception screen 181) is output to the output unit 140 and requested by the customer via the input unit 130. It accepts input of optimization conditions.

  The optimization condition input acceptance screen 181 includes a target product input area 181a, a reference product input area 181b, a priority index input area 181c, a cost target value input area 181d, an environmental load input area 181e, and a delivery date input area 181f. And a confirmation instruction input area 181g.

  In the target product input area 181a, input of information specifying a target system product to be optimized is received. Here, in this embodiment, the names of system products stored in the evaluated product name field 164a of the evaluated product table 164 shown in FIG. 27 are registered in advance as pull-down menus. Have been able to.

  In the reference product input area 181b, input of information for specifying a reference system product as a reference for comparison with the system product proposed to the customer is received. Here, in this embodiment, the names of system products stored in the evaluated product name field 164a of the evaluated product table 164 shown in FIG. 27 are registered in advance as pull-down menus. Have been able to.

  In the priority index input area 181c, an input of information for specifying an index in which the customer has the highest priority for the system product is received. Here, the priority index is selected from “cost” of the system product, “environmental” load of the system product, and processing “capability” of the system product.

  In the cost target value input area 181d, input of information specifying how much the cost should be increased or decreased from the cost of the target system product is received. In the present embodiment, the cost can be selected from “reduction”, “increase”, “reduction as much as possible”, or “unquestioned”, and “reduction” or “increase” is selected. In this case, the reduction rate or the increase rate is accepted in the numerical value input field 181h.

  In the environmental load input area 181e, input of information specifying how much increase or decrease in environmental load is desirable from the environmental load of the target system product is received. In the present embodiment, the environmental load can be selected from “reduction”, “increase”, “reduction as much as possible” or “unquestioned”, and “reduction” or “increase” is selected. In the case of an error, the reduction rate or the increase rate is accepted in the numerical value input field 181i.

  In the delivery date input area 181f, input of information specifying the date of delivery of the system product is received. If the customer does not request a delivery date, leave this field blank.

  Here, it is also possible to associate the selection of the priority index with the input of the cost target and the environmental load. For example, when “cost” is selected in the priority index, “increase” or “unquestioned” cannot be selected in the cost target value input area 181d, while “environment” is selected in the priority index. In such a case, by making it impossible to select “increase” or “unquestioned” in the environmental load input area 181e, it is possible to avoid unnecessary (nonsense) input.

  Then, the optimization condition input reception unit 126 displays the optimization condition input reception screen 181 by receiving the input of necessary information in the above input area and receiving the input of the execution instruction specifying the confirmation instruction input area 181g. The information received via the input is stored in the optimization condition table 168 as shown in FIG. 32 and stored in the temporary information storage area 117.

  The optimization condition table 168 includes a target product ID field 168a, a reference product ID field 168b, an optimized product ID field 168c, a priority index field 168d, a cost field 168e, an environmental load field 168f, and a delivery date field 168g. And an evaluation date field 168h.

  In the target product ID field 168a, information for specifying an ID corresponding to the name of the target system product input in the target product input area 181a of the optimization condition input reception screen 181 is stored. This ID matches the ID stored in the ID field 164b of the evaluated product table 164.

  In the reference product ID field 168b, information for specifying an ID corresponding to the name of the target system product input in the reference product input area 181b of the optimization condition input reception screen 181 is stored. This ID matches the ID stored in the ID field 164b of the evaluated product table 164.

  The optimized product ID field 168c stores an ID assigned so as to be unique to the system product that optimized the target system product. The ID is assigned by the optimization condition input receiving unit 126 so as to be unique according to a predetermined rule.

  Information input in the priority index input area 181c of the optimization condition input reception screen 181 is stored in the priority index field 168d.

  Information input in the cost target value input area 181d of the optimization condition input reception screen 181 is stored in the cost field 168e.

  The information input in the environmental load input area 181e of the optimization condition input reception screen 181 is stored in the environmental load field 168f.

  In the delivery date field 168g, information input in the delivery date input area 181f of the optimization condition input acceptance screen 181 is stored. When the delivery date input area 181f is blank, this field is also blank.

  The evaluation date / time field 168h stores information for specifying the date when the target system product is evaluated again for optimization.

  FIG. 33 is a flowchart of the product configuration optimization process in step S14 of FIG.

  First, the optimization evaluation unit 127 generates a constraint condition expression (S40). Here, in this embodiment, the optimization evaluation unit 127 first generates a delivery date constraint equation and a life constraint equation.

Here, the conditional expression generation method is as follows: i is a substitute product of the product n constituting the system, i is a counter in the inventory of i, and k is a distinction of a planned shipping date, and a variable representing the quantity of the substitute product is X _nijk and The quantity of product n will be described as _Xn . The replaceable quantity at this time is Y _nijk . Since the stock includes reuse stock, the life is L _nijk and the discount rate is R _nijk . Furthermore, _let T _{nijk be the} delivery date margin and A _{nijk be the} ability influence index.

First, the optimization evaluation unit 127 records the model number of the record whose ID stored in the ID field 165f of the evaluated component table 165 shown in FIG. 28 matches the ID of the target system product to be optimized. The model number stored in the field 165c is specified one by one and read as n, and the quantity stored in the quantity field 165d of the record corresponding to the _n is read as _Xn .

  Next, the optimization evaluation unit 127 identifies one record that matches the model number n one by one from the model number field 116b of the substitute product table 116a stored in the substitute product information storage area 116, and substitute item model number of the record. The model number stored in the field 116c is read as i. If there is no record that matches the model number n in the model number field 116b, the next model number stored in the model number field 165c of the record that matches the ID of the target system product to be optimized is set as n. Repeat reading and processing.

Next, the optimization evaluation unit 127 identifies a record in which the model number stored in the model number field 115c of the inventory table 115a stored in the inventory information storage area 115 matches the model number i. 1 is added to j (the initial value of j is 0). With respect to the inventory, if the evaluation date is the scheduled shipping date, the delivery date constraint T _nijk = delivery date−scheduled shipping date ≧ 0 is satisfied.

  Next, the optimization evaluation unit 127 identifies a record in which the model number stored in the model number field 111b of the component table 111a stored in the component information storage area 111 matches the model number i. If there is, the service life is obtained from the service life field 111j of the record, and it is confirmed whether or not the following life constraint is satisfied.

Life L _nijk = lifetime−usage time ≧ use years of system product.

  Here, the usage time is stored in the usage period field 115d of the inventory table 115a corresponding to the model number i, and the usage years of the system products are stored in the product usage years field 164c of the evaluated product table 164. .

Then, if the lifetime constraint is satisfied, the optimization evaluation unit 127 increments Y _nijk by “1” (the initial value of Y _nijk is 0), and the discount rate field 115e of the record corresponding to i in the inventory table 115a _Is read as R _nijk .

On the other hand, when the lifetime constraint is not satisfied, the optimization evaluating unit 127 does not increment Y _nijk and sets R _nijk = 0. In addition, the ability influence index A _nijk stores a numerical value stored in the ability influence index field 116d of the alternative product table 116a corresponding to the model number i.

  The optimization evaluation unit 127 repeats the above process until there is no alternative product stored in the model number i. If there is no alternative product, j = 0 and the process of the next step is performed.

  Next, the optimization evaluation unit 127 searches the model number field 114b of the shipping plan table 114a stored in the shipping plan information storage area 114 with the model number i of the alternative product. (The initial value of k is 0).

Then, since the replacement product to be shipped from now on has an in-use period = 0, the optimization evaluation unit 127 satisfies the life constraint by the life L _nijk = the service life ≧ the service life of the system product.

  Further, the optimization evaluation unit 127 confirms the delivery date constraint as follows.

Delivery time margin T _nijk = Delivery date−Scheduled shipping date ≧ 0.

  Here, the delivery date is stored in the delivery date field 168g corresponding to the target system product in the optimization condition table 168, and the estimated shipping date is stored in the estimated shipping date field 114c corresponding to the model number i in the shipping plan table 114a. Yes.

If the delivery date constraint is satisfied, the optimization evaluation unit 127 adds the quantity stored in the quantity field 114d corresponding to the model number i in the shipment plan table 114a to Y _nijk , and further _sets R _nijk = 0. Set.

Further, the optimization evaluating unit 127 includes a delivery date delay even when the delivery date constraint is not satisfied (when the operator of the product configuration information creation apparatus 100 inputs an instruction to include the delivery date delay via the input unit 130). ) _{Adds the} quantity stored in the quantity field 114d corresponding to the model number i of the shipment plan table 114a to Y _nijk and sets R _nijk = 0. On the other hand, when the delivery date delay is not included, Y _nijk is not added, and R _nijk = 0 is set.

Further, the optimization evaluation unit 127 stores the numerical value stored in the capability impact index field 116d of the alternative product table 116a in the capability impact index A _nijk .

  The optimization evaluation unit 127 repeats until the model number field 114b of the shipping plan table 114a has no match with the model number i of the alternative product, and if it does not exist, sets k = 0 and performs the process of the next step.

  Next, the optimization evaluation unit 127 performs optimization processing (S41).

  First, the optimization evaluation unit 127 generates an inventory constraint equation represented by the above-described equation (4), a cost constraint equation represented by the equation (5), and an environment constraint equation represented by the equation (6).

  The optimization evaluation unit 127 generates the following equation (22) as an inventory constraint equation.

  Next, the optimization evaluation unit 127 generates the following equation (23) as a cost constraint equation.

  Here, the introduction cost of the optimization target system product is calculated by the following equation (24).

ここで、型番ｉの単価は、構成品テーブル１１１ａの型番フィールド１１１ｂに格納された型番が型番ｉに一致するレコードの単価フィールド１１１ｅに格納されている数値である。

Here, the unit price of the model number i is a numerical value stored in the unit price field 111e of the record whose model number stored in the model number field 111b of the component table 111a matches the model number i.

  The unit price of the model number n is a numerical value stored in the unit price field 111e of the record whose model number stored in the model number field 111b of the component table 111a matches the model number n.

  Further, the sum of the cost of shipping, procurement, transportation, installation, start-up and maintenance of the target system product is stored in the evaluation classification row 167a of the evaluated evaluation tabulation table 167 in which the ID of the target system product is stored in the ID row 167z.

It is a numerical value.

  Since the life cycle condition table 162 shown in FIG. 24 is regenerated by the above processing, the optimized target is obtained by performing the product evaluation processing (S11) and the evaluation result output processing (S12) shown in FIG. The system cost and environmental load can be evaluated.

  Then, a unique ID is assigned again to the optimized target system, and the evaluated product table 164, the evaluated product configuration table 165, the evaluated life cycle condition table 166, and the evaluated evaluation totaling table 167 are stored in the evaluation result storage area 118.
