Recently, consumers are increasingly purchasing fresh foods such as salads and fruits for health or diet purposes. Reflecting this tendency, stores such as marts or convenience stores sell products that can be easily ingested by selling prepared vegetables to easily make and eat salads, or by removing the wrapping paper. In recent years, The number of fresh food specialty stores is increasing.

However, salads sold in stores or these fresh food products are difficult to maintain freshness and do not vary in variety, so there is a limit to purchasing products desired by consumers. In addition, although the fresh food specialty store can purchase fresh and various salads, there is a problem that consumers have to visit the store directly, and the salad can not be purchased if there is no store near the consumer's location.

To solve these problems, recently, a service for delivering fresh food at a house or a company has been proposed.

However, the conventional fresh food delivery service is similar to a general courier delivery service, so that consumers are required to order fresh foods to be consumed for a certain period of time at once or have a heavy burden of shipping costs, and it is difficult to maintain the freshness of fresh foods.

In addition, the general courier delivery service has a problem in that it is difficult to change the delivery receipt destination because it is operated by only one route for a single delivery person on a daily basis, and it is difficult to cover the delivery destination alone when the delivery quantity is large.

Accordingly, it is required to develop an efficient method of determining a fresh food delivery route that can deliver salads to consumers at a desired place or time.

Referring to FIG. 3, a method for determining a fresh food delivery path according to an embodiment of the present invention includes receiving total resource availability data and destination data from a terminal of a manager managing a server (S100) (S200) of creating at least one destination group including a plurality of destinations based on the destination data, a step (S300) of allocating the available resources to each destination group based on the total available shipping resource data (S300) (S400) of generating at least one delivery route connecting a plurality of delivery destinations included in the group (S500), and providing the delivery article terminal to display a plurality of delivery routes (S500).

In this embodiment, the first terminal 210 may be an administrator terminal managing the server, the second terminal 220 may be a terminal of a delivery engineer, the third terminal 230 may be a terminal of a consumer, The food may be the terminal of the recipient.

First, in the method of determining a fresh food delivery route according to the present invention, all the available shipping resource data and destination data are received from the first terminal 210 (S100). The total shipping available resource data and destination data may be data input to the first terminal 210 from an administrator managing the server or may be data collected in the first terminal 210 or may be data collected or processed in the first terminal 210 Lt; / RTI > Since the total shipping availability resource data and destination data are as described above, a detailed description will be omitted.

Next, in the fresh food delivery place determination method, at least one destination group including a plurality of destinations is created based on the total shipping availability resource data and destination data received in the previous step (S100) (S200).

Points 1 to 9 shown in FIGS. 5A and 5B indicate the first to ninth destinations, respectively, which indicate destinations to be delivered in the same time zone. 5A and 5B illustrate that three destination groups S50, S60, and S70 are generated. However, the number of destination groups S50, S60, and S70 is not limited to the total available source data Can be determined according to the destination data.

The destination groups (S50, S60, S70) group the plurality of destinations according to predetermined criteria. For example, the destination groups (S50, S60, and S70) may be configured as destinations of nearby locations as shown in FIG. 5A. The destination groups S50, S60, and S70 may be configured such that the total number of deliveries of the destination groups S50, S60, and S70 is equal to each other. Cost or distance may be the same.

If the total number of deliveries, the cost of delivering, or the distance of delivery of each of the destination groups S50, S60, and S70 is the same, as shown in FIG. 5B, S60 ', and S70').

On the other hand, the destinations may be displayed at different positions over time, and the destinations configured in the destination groups (S50, S60, S70) may be all destinations in the same region or may be different regions.

Next, based on the total shipment availability resource data, the shipment resource is allocated to each shipping group (S300).

6, considering the characteristics of each of the destination groups S50, S60, and S70, the destination S50, S60, and S70 are allocated to the destination groups S50, S60, and S70, A large vehicle such as a truck may be assigned, or a relatively large number of vehicles or persons may be assigned. Conversely, when the amount of deliveries of the destination group S50, S60, S70 is small or the delivery distance is short, a motorcycle or a small car may be allocated, or a relatively small number of vehicles or personnel may be allocated.

Next, at least one delivery route connecting the plurality of delivery destinations included in the destination group is generated (S400).

The delivery path creation step (S400) creates a delivery path via each of the delivery destinations included in each of the destination groups S50, S60, and S70.

Referring again to FIG. 5A, the first destination group S50 includes first to third destinations. At this time, the delivery route can be generated by various routes as shown in Table 1 below.

Order via Shipping path first second third First delivery destination Second delivery destination Third destination One Third destination Second delivery destination 2 Second delivery destination First delivery destination Third destination 3 Third destination First delivery destination 4 Third destination First delivery destination Second delivery destination 5 Second delivery destination First delivery destination 6

Referring to Table 1, if the first waypoint of the first destination group S50 is the first destination, the second waypoint may be the second destination or the third destination. If the second waypoint is the second destination, the third waypoint becomes the third destination, and if the second waypoint is the third destination, the third waypoint becomes the second destination.

At least one delivery route can be created in the above-described manner even if the first stopping place of the first destination group S50 is the second destination or the third destination, and the number of the destinations belonging to the destination group S50, S60, S70 The greater the number, the more delivery paths are created.

At this time, a step of determining one of the generated delivery routes as a recommended delivery route based on the delivery destination data may be further performed (S410).

Here, the recommended shipping route may be a shortest route having the shortest distance connecting the plurality of destinations belonging to the destination group (S50, S60, S70), a minimum time route having the shortest time to connect the plurality of destinations, And the minimum cost path that requires the least amount of cost.

Next, the second terminal 220 displays the generated delivery route (S500).

The delivery route may display only the recommended delivery route as shown in FIG. 7, but it may be provided to display all the delivery routes generated in the delivery route creation step (S400).

As shown in FIG. 7, the delivery engineer can select a final delivery path to be delivered on the screen provided on the second terminal 220 according to the situation. Accordingly, the fresh food delivery route determining apparatus 100 receives one final delivery route selected from the plurality of delivery routes from the second terminal 220 (S600).

Accordingly, the fresh food delivery route determining apparatus 100 guides the second terminal 220 to the route corresponding to the received final delivery route (S610).

[0051] Meanwhile, when a change occurs in the entire shipping available resource data and the delivery destination data received from the first terminal 210, a step S200 of generating a destination group based on the changed data, a step S300 of allocating data, A step S400 of generating a delivery route and a step S500 of providing a delivery route display screen are executed again.

For example, when the number of the entire delivery vehicles or the total number of deliverable persons is changed, the number of the destination groups S50, S60, and S70 to be generated can be changed, and the number of the destination groups S50, S60, and S70 The number of the shipping available resources and the number of the delivery routes of the destination group S50, S60, and S70 allocated to the destination groups S50, S60, and S70 may be changed.

Specifically, when the number of total delivery vehicles or the total number of deliverable members increases, the number of the destination groups S50, S60, and S70 generated may be increased so that the number of destinations included in each group may be reduced. Accordingly, the number of generated delivery routes can be reduced, and the total delivery distance of each of the destination groups S50, S60, and S70 can be shortened.

On the contrary, when the number of the entire delivery vehicles or the total number of deliverable persons decreases, the number of the destination groups S50, S60, and S70 generated may be decreased so that the number of destinations included in each group may be increased. Accordingly, the number of generated delivery routes may increase, and the total delivery distance of each of the destination groups S50, S60, and S70 may become long.

On the other hand, the fresh food delivery route determining apparatus 100 transmits the position and the estimated delivery time of the second terminal 220 to the third terminal 230 (S700), and visually (S710).

In addition, the fresh food delivery path determining apparatus 100 provides a function of changing the destination of delivery at the third terminal 230. The user using the third terminal 230 can change the destination within the same destination group as the set destination, or change the destination by selecting the destination of the other destination group.

For example, referring to FIG. 8, the destination set in the third terminal 230 is a third destination. At this time, the third terminal 230 can change the destination to the first destination and the second destination of the first destination group S50, which is the same destination group as the third destination.

In addition, the third terminal 230 may display a point where the destination can be changed and a point where the destination can not be changed. Specifically, the first destination, the second destination, the fifth destination, the seventh destination, and the ninth destination are the destination where the destination can be changed, and the fourth destination, the sixth destination, and the eighth destination, , It is possible that the point at which the destination can be changed and the point at which the destination can be changed are displayed differently. The user using the third terminal 230 can change the destination of the delivery by selecting the destination where the destination can be changed.
