The inquiry receiving unit 4915 determines whether or not the required time inquiry information for inquiring the required time corresponding to the supply chain model has been received from the user interface 4904. Here, when the user performs an operation for inquiring the required time through the user interface 4904, the inquiry receiving unit 4915 receives the required time inquiry information. The required time inquiry information includes model identification information of the supply chain model related to the inquiry from the user and information indicating a month and a time zone to which the model identification information is applied.

The required time presentation unit 4916 uses the average required time information stored in the required time DB 4932 to calculate the average required time corresponding to the combination of the model identification information included in the required time inquiry information and the month and time zone to which the supply chain model is applied. It is determined whether time information exists. Then, when the required time presenting unit 4916 determines that the average required time information described above is included in the average required time information stored in the required time DB 4932, the average required time indicated by the average required time information and the route stability corresponding thereto The route stability index value indicated by the index value information is presented via the user interface 4904. In addition, when the required time presentation unit 4916 determines that the average required time information does not exist in the average required time information stored in the required time DB 4932, the required time theoretical value information acquired from the model generation device 4001 indicates The theoretical time required value is presented via the user interface 4904.

Next, a part of the operation of the supply chain model generation system according to this modification will be described with reference to FIG. Note that, in FIG. 30, the same processes as those in the supply chain model generation system described in the embodiment are designated by the same reference numerals as those in FIG. 18. After the series of processes up to step S41 is executed, the model generation device 4001 calculates the theoretical value of the required time corresponding to the generated supply chain model, and stores the calculated theoretical value in the theoretical value DB 4133 of the required time. (Step S4001).

Next, when the required time calculation device 4009 acquires the required time actual value information (step S4002), it generates theoretical value request information for requesting the model generation device 4001 to transmit the required time theoretical value information. (Step S4003). Subsequently, the generated theoretical value request information is transmitted from the required time calculation device 4009 to the model generation device 4001 (step S4004). The theoretical value request information includes the model identification information included in the required time actual value information. On the other hand, the model generation device 4001 identifies the required time theoretical value information corresponding to the supply chain model to which the model identification information included in the theoretical value request information is added (step S4005). Then, the specified theoretical time information of required time is transmitted from the model generation device 4001 to the required time calculation device 4009 (step S4006).

On the other hand, when the required time calculation device 4009 receives the required time theoretical value information, it stores the received required time theoretical value information in the actual result DB4931 in association with the required time actual value information (step S4007).

After that, the required time calculation device 4009 calculates the average required time corresponding to the applicable month and the applicable time zone to which the performance occurrence date and time of the acquired required time performance value information belongs (step S4008). The required time calculation device 4009 stores the average required time information indicating the calculated average required time in the required time DB 4932. Next, the required time calculating device 4009 calculates a route stability index value corresponding to the ratio of the average required time to the theoretical required time (step S4009). The required time calculating device 4009 stores the route stability index value information indicating the calculated route stability index value in the required time DB 4932 in association with the average required time information and the model identification information.

Further, for example, it is assumed that a user who belongs to the production control department performs an operation for inquiring the required time through the user interface. In this case, the required time calculation unit 4009 receives the required time inquiry information (step S4010). Subsequently, the required time calculation device 4009 searches the required time information stored in the required time DB 4932, and handles the combination of the model identification information included in the required time inquiry information and the month and time zone to which the supply chain model is applied. It is assumed that it is determined that there is the average required time information (step S4011). In this case, the required time calculation device 4009 acquires the average required time information and the route stability index value information from the required time DB 4932, and the average required time indicated by the acquired average required time information and the route indicated by the route stability index value information. The stability index value and the stability index value are presented via the user interface 4904 (step S4012).

Next, the model generation processing executed by the model generation device 4001 according to this modification will be described with reference to FIG. Note that in FIG. 31, the same processing as the model generation processing described in the embodiment is denoted by the same reference numeral as in FIG.

First, after the series of processing from steps S401 to S405 is executed, the required time theoretical value calculation unit 4114 calculates the required time theoretical value corresponding to the supply chain model generated by the model generation unit 113, and the required time It is stored in the theoretical value DB 4133 (step S4401). Next, the required time theoretical value transmission unit 4115 determines whether or not the above theoretical value request information is received from the required time calculation device 4009 (step S4402). When it is determined by the required time theoretical value transmission unit 4115 that the theoretical value request information has not been received (step S4402: No), the process of step S406 is executed. On the other hand, when it is determined that the theoretical value transmission unit 4115 has received the theoretical value request information (step S4402: Yes), the required time corresponding to the supply chain model indicated by the model identification information included in the theoretical value request information. The theoretical value information is specified (step S4403). Subsequently, the required time theoretical value transmission unit 4115 transmits the specified required time theoretical value information to the required time calculation device 4009 (step S4404). Then, the process of step S406 is executed.

Next, the average required time/route stability index value calculation processing executed by the required time calculating device 4009 according to the present modification will be described with reference to FIG. The average required time/route stability index value calculation process is started, for example, when the required time calculating device 4009 is powered on. First, the actual value acquisition unit 4911 determines whether the required time actual value information has been acquired (step S4901). When the actual value acquisition unit 4911 determines that the required time actual value information has not been acquired (step S4901: No), the process of step S4907 described below is executed as it is.

On the other hand, the actual value acquisition unit 4911, when acquiring the required time actual value information (step S4901: Yes), stores the acquired required time actual value information in the actual DB 4931 (step S4902). Next, the theoretical value acquisition unit 4912 extracts model identification information from the required time actual value information, generates theoretical value request information including the extracted model identification information, and transmits it to the model generation device 4001 (step S4903). Subsequently, the theoretical value acquisition unit 4912 acquires the required time theoretical value information from the model generation device 4001 and stores the acquired required time theoretical value information in the required time DB 4932 (step S4904).

After that, the average required time calculating unit 4913 classifies the acquired required time actual value information by the combination of the month and the time zone to which the corresponding supply chain model is applied (step S4905). Next, the average required time calculation unit 4913 calculates an average required time that is the average value of the required time actual values indicated by the required time actual value information for each combination of the month and the time zone to which the supply chain model is applied. Then, the average required time information indicating the calculated average required time is stored in the required time DB in association with the model identification information, the month and the time zone (step S4906). Subsequently, the stability index value calculation unit 4914 calculates a route stability index value corresponding to the ratio of the average required time to the theoretical required time for each combination of the month and the time zone to which the supply chain model is applied. The route stability index value information indicating the calculated route stability index value is stored in the required time DB 4932 (step S4907).

After that, the actual value acquisition unit 4911 determines whether or not there is an end command instructing to end the average required time/route stability index value calculation processing (step S4908). This end command is generated, for example, when the user performs an operation for stopping the required time calculation device 4009. When the actual value acquisition unit 4911 determines that there is no end command (step S4908: No), the process of step S4901 is executed again. On the other hand, when the actual value acquisition unit 4911 determines that there is an end command (step S4908: Yes), the average required time/route stability index value calculation process ends.

Next, the required time presentation processing executed by the required time calculation device 4009 according to the present embodiment will be described with reference to FIG. The required time presentation process is started, for example, when the required time calculating device 4009 is powered on.

First, the inquiry receiving unit 4915 determines whether or not the required time inquiry information for inquiring the required time corresponding to the supply chain model has been received from the user interface 4904 (step S4951). Here, when the user performs an operation for inquiring the required time through the user interface 4904, the inquiry receiving unit 4915 receives the required time inquiry information. As long as the inquiry receiving unit 4915 determines that the required time inquiry information has not been received (step S4951: No), the process of step S4951 is repeatedly executed.

On the other hand, it is assumed that the inquiry receiving unit 4915 receives the required time inquiry information (step S4951: Yes). In this case, the required time presentation unit 4916 searches the required time information stored in the required time DB 4932, and compares the model identification information included in the required time inquiry information with the information indicating the month and the time zone to which the supply chain model is applied. It is determined whether or not the average required time information corresponding to the combination exists (step S4952).

The required time presenting unit 4916 determines that the required time information stored in the required time DB 4932 includes the average required time information corresponding to the combination of the model identification information and the information indicating the applied month and time zone. (Step S4952: Yes). In this case, the required time presentation unit 4916 acquires the average required time information and the route stability index value information from the required time DB 4932, and the average required time indicated by the acquired average required time information and the route indicated by the route stability index value information. The stability index value is presented via the user interface 4904 (step S4953).

On the other hand, the required time presentation unit 4916 does not include average required time information corresponding to the combination of the model identification information and the information indicating the applied month and time zone in the required time information stored in the required time DB 4932. It is assumed that it is determined (step S4952: No). In this case, the theoretical value acquisition unit 4912 extracts the model identification information from the required time inquiry information, generates theoretical value request information including the extracted model identification information, and transmits the theoretical value request information to the model generation device 4001 (step S4954). Next, the theoretical value acquisition unit 4912 acquires required time theoretical value information from the model generation device 4001 (step S4955). Subsequently, the required time presentation unit 4916 presents the required time theoretical value indicated by the required time theoretical value information acquired by the theoretical value acquisition unit 4912 via the user interface 4904 (step S4956).

With this configuration, it is possible to present the user with the time required from the ordering of the final product to the supply of the final product to the orderer according to the supply chain model, so that the user can easily understand the time when the final product is supplied. Has the advantage that In addition, according to this configuration, since the index value of the stability of the distribution channel according to the supply chain model can be presented to the user, the user can apply it in consideration of the stability of the distribution channel according to the supply chain model. There is also an advantage that it is possible to select the supply chain model to be used.

In this modification, the example of the supply chain model generation system including the average required time calculating unit 4913 that calculates the average required time that is the average value of the required time actual values as the representative value of the actual required time values has been described. However, the present invention is not limited to this, and, for example, the supply chain model generation system includes a representative value calculation unit that calculates the maximum value, the intermediate value, or the minimum value of the required time actual values as the representative value of the actual required time values.
