The operation of the mobile logistics management system according to the preferred embodiment of the present invention will now be described in detail.

First, an agent terminal (200) used by a contact person terminal (100) used by a contact person in charge of the head office, a supplier terminal (300) used by a person in charge of a goods supplier, To register information on the ordering and delivery process of the goods. Here, each terminal registration registers information such as an ID, a password, a telephone number, and the like through a head office system in such a manner that an account is assigned.

In a state where each terminal is registered, the transaction limit changing unit 108 of the headquarters contact terminal 100 sets a transaction limit for mutual credit for ordering and ordering between the store and the article supplier. The transaction limit is meant to place orders through credit or deliver goods without actually paying for them.

Here, the transaction limit is set according to a preset standard in the transaction limit changing unit 108 based on information such as the size of each store, creditworthiness, transaction details, etc., or is determined by the head office, It is set by the method of registration.

When the transaction limit is set, the transaction limit is transmitted to the merchant terminal 200 and the supplier terminal 300 of the store using the smartphone push notification service through the communication module 101 of the headquarters personnel terminal 100. Here, the supplier terminal 300 executes the mobile logistics application, and the transaction limit processing unit 308 may request the head office clerk terminal 100 to change the transaction limit for the merchant in accordance with the article delivery performance with the store or the current status have. In response to such requests, the head office may change the transaction limit of the merchant through deliberation.

The representative of the merchant executes the mobile logistics application, confirms the transaction limit using the logistics merchant terminal 200, designates the goods supplier through the input unit 202, creates an article list within the supply transaction limit, And orders the article supplier through the guide portion 206.

At this time, the order information is transmitted to the head office personnel terminal 100 and the supplier terminal 300 by using the smartphone push notification service. Upon receiving the order information, the notification history processor 307 of the supplier terminal 300 performs a response to the order (order response). The order information generated in this manner is processed in the notification history processing unit 110 of the head office personnel terminal 100 and further processed in the notification history processing unit 207 of the agent terminal 200 so that the store manager confirms the order information.

Then, the goods delivery processor 306 of the supplier terminal 300 performs the supply delivery process for the ordered goods (setting the delivery due date and processing information about the delivery), and supplies the goods delivery information to the headquarters personnel terminal 100 And the merchant terminal 200 as shown in FIG. Here, the sales / inventory processing unit 311 of the supplier terminal 300 performs sales and inventory processing for delivering goods.

As described above, according to the present invention, the supplier and the head office personnel can recognize the order information in real time. In addition, the manager in charge of the store and the designated person in charge of the head office can know that the supplier recognized the order in real time through the order information, Once the inventory of the order items is checked and delivered, the delivery information can be checked in real time by the store manager and the head office personnel.

Meanwhile, another feature of the present invention is that the supplier can conveniently manage the status of the trial. For example, the purchase status processing unit 309 of the supplier terminal 300 classifies the receipt status of each store into the storage unit 303, fetches the receipt status of the store according to the request of the person in charge, . The logistics control unit 304 transmits the trial status information to the head office clerk terminal 100 and the merchant terminal 200 using the smartphone push notification service through the communication module 301. [

The notification history processing unit 207 of the merchant terminal 200 notifies the person in charge using the notification service when receiving the current status information and displays the current status through the display unit 205 at the request of the person in charge. This makes it easy for the person in charge to know the status of the vendor.

Here, the headquarters manages the current status of the tentative request, and upon receiving a request from the supplier terminal 300, the head tang operator terminal 100 transmits the tentative current status information to the supplier terminal 300, It is also possible to transmit the current status information of the shop to the franchise terminal 200 and the supplier terminal 300 simultaneously.

By using this method, suppliers can conveniently and easily manage the status of each store.

On the other hand, as another feature of the present invention, the article price change is possible in real time.

For example, when a change in the article price occurs, the supplier manager instructs the input unit 302 to process the request for price change. In response to this command, the price change processing unit 310 transmits price change information of the changed article to the head office clerk terminal 100 in association with the distribution control unit 304, and requests the price change. When a request for price change is made by the supplier, the head office determines whether it is valid or not and approves or rejects the request. In the case of rejection of the price change request, only the rejection information is transmitted to the provider terminal 300, the notification history processor 307 processes the rejection information, and then displays the rejection information through the display unit 305, Information can be known in real time. In addition, when approved for the price change request, the approval information is simultaneously transmitted to the merchant terminal 200 and the supplier terminal 300. The notification history processing unit 207 of the merchant terminal 200 receives the price change information and displays it through the display unit 205 so that the person in charge of the store can recognize the change in the article price in real time. In addition, the person in charge of the supplier recognizes approval information of the request for changing the price of the goods through the supplier terminal 300, and after that, supplies the goods with the changed price information.

Meanwhile, another feature of the present invention is that the sales can be easily managed by the supplier and the merchant.

For example, the franchise manager requests information on the sales status to the head office clerk terminal 100 by using the franchise terminal 200, and the supplier clerk uses the supplier terminal 300 to transmit the sales You will be asked for information about the status.

Here, the main office system analyzes and stores the sales status (card sales, cash sales, net sales, number of sales, customer price, etc.) by each store and date, When the status request is generated, the sales status of each store or supplier is transmitted to the merchant or the supplier by using the head office personnel terminal (100). As a result, merchants and suppliers can conveniently check the status of sales, and merchants will use the sales status information for store management consulting.

Meanwhile, another feature of the present invention is that, like the above-described sales management method, it is possible to manage partner companies, inventory management, and the like. In particular, during inventory management, each supplier and store identifies the current inventory and notifies the head office through alarm messages when the inventory quantity drops to a certain level for each item. This allows us to see suppliers and store inventory at a glance and take appropriate action according to the quantity of inventory so that inventories of stores and suppliers of goods are always maintained properly. In addition, it also manages partner information (address, contact person, contact, etc.) and manages the direct communication by mutual transfer if necessary.

FIG. 5 is a screen configuration diagram displayed on the main screen when the mobile logistics management application is executed in the main office personnel terminal, the merchant terminal, and the supplier terminal in the present invention. FIG. 5 is a diagram showing an example of a main menu screen displayed on the head office personnel terminal, and includes items such as a delivery status, an actual status, a transaction limit, a price change request, a notification history, a sales status, a card sale,

Items of the main menu may be set differently between the main office personnel terminal, the merchant terminal, and the supplier terminal as required. Items of the main menu may be changed.

Although the present invention has been described in detail with reference to the above embodiments, it is needless to say that the present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the spirit of the present invention.

The present invention is effectively applied to technologies for managing history, ordering and ordering, sales and inventory management, and managing the current status between a head office, a franchise store, and a supplier using a smartphone push notification service using a mobile logistics management application.
