This application relates to a real-time price management system, and more particularly, to a system which is able to automatically adjust merchandise's price according to the purchase date.

2. Description of the Related Art

The traditional merchandise on the market, generally, is of fixed price, but as far as those with expiration date are concerned, such as food, it is unexceptional to be sold with the same price. Therefore, in terms of the consumers, it is the inexorable trend that they want to purchase the merchandise which is dated closer to production date thereof. It proves, the merchandise which is far away production date thereof can't have the consumers' favor, and once the expiration date of the merchandise is exceeded, the store can only destroy it, and as a result, it not only leads to waste, but also increases the cost burden towards the store.

In order to resolve the problem, the merchandise which is about to expire is usually placed in front of showcase, or by means of promotion such as short-term preferential price, discount or with free gift and so on to attract consumers' purchase desire. These methods, however, are negative and have little reaction, and additionally, application of human resource may limit its effectiveness.

In addition, as far as the non-edible goods are concerned, such as 3C products, time plays a critical role in the price fluctuation towards the products. Generally, store often re-prices those products by labor power, but it may cause errors in the price. In addition, the real-time determination can't be made based on the launch date of the product, resulting that the store is incapable of determining the price of current merchandise accurately.

Therefore, in accordance with an exemplary embodiment of the present invention, the input device 12 may scan the barcode 11 and to transfer the initial price, terminal price, production date and expiration date contained in the barcode 11 to the computer system 13 through the input device 12 which is electrically connected to the computer system 13. In addition, the input device 12 may simultaneously record the purchase date of the merchandise in the computer system. It is noteworthy that the purchase date mentioned in the present invention may not certainly the date buying the merchandise. The purchase date of the present invention only indicates the date contained in the barcode 11 which is scanned by the input device 12 and transferred to the computer system 13. Therefore, the purchase date may indicate the date of merchandise information contained in the barcode 11 which is received by the computer system 13.

Afterwards, the computer system 13 specifies the purchase date into the price-time equation to obtain a real-time price corresponding to the purchase date. Wherein, the price-time equation may be a price-time mathematical equation which is defined by the merchandise information contained in the barcode 11. The merchandise information may include the initial price, terminal price, production date and expiration date of the merchandise. In accordance with an exemplary embodiment of the present invention, the price-time equation is used to enable the computer system 13 performing real-time calculation towards the real-time price corresponding to the purchase date. In addition, when the computer system 13 calculates the real-time price corresponding to the purchase date, the display device 16 which is electrically connected to the computer system is configured to display the real-time price. According to this, this transformation may lead to the different way of displaying the price of the merchandise. New price tags do not need to be printed and labeled on the merchandise. The customer can easily obtain the correct and real-time price.

In accordance with an exemplary embodiment of the present invention, the obtained real-time price may be smaller or equal to the initial price, and may be higher or equal to the terminal price. For example, when the purchase date is equal to the production date, the real-time price is equal to the initial price. Besides, when the purchase date is equal to the expiration date, the real-time price is equal to the terminal price.

Please refer to FIG. 2 which is a curve diagram of a price-time equation in accordance with an exemplary embodiment of the present invention. Wherein, an exemplary embodiment of the price-time equation shown in FIG. 2 can be seen as the following equation (1):

$\begin{array}{cc}P=\mathrm{Pi}-\frac{\mathrm{Pi}-\mathrm{Pn}}{\mathrm{Tn}-\mathrm{Ti}}\times \left(T-\mathrm{Ti}\right).& \mathrm{equation}\left(1\right)\end{array}$

Wherein, P may be the real-time price, T may be the purchase date, P_i may be the initial price, P_n may be the terminal price, T_i may be the production date and T_n may be the expiration date.

It can be found through the preceding explanation that the merchandise information contained in the barcode 11 may have included the initial price P_i, the terminal price P_n, the production date T_i and the expiration date T_n. The purchase date T may be recorded in the computer system 13 when the input device 12 is transferring the merchandise information.

The purchase date T may be recorded in the computer system 13 when the input device 12 is transferring the merchandise information. Therefore, as FIG. 4 and the equations (4) and (5) show that by means of specifying the initial price P_i, the terminal price P_n, the production date T_i and the expiration date T_n to equation (5) may obtain numerical α, and then the variable α, the terminal price P_n, the production date T_i and the purchase date T which are all known may be specified to equation (4) to hence obtain the real-time price P corresponding to the purchase date T

Please refer to FIG. 1 once again. The computer system 13 may further include a first logical device 14 configured to determine whether the real-time price P is lower than the terminal price P_n. When the real-time price P is determined lower than the terminal price P_n, computer system may replace the numerical of the real-time price P with the numerical of the terminal price P_n. Therefore, in accordance with an exemplary embodiment of the present invention, when the real-time price P is determined lower than terminal price P_n, the real-time price P shown in the display device 16 is equal to the terminal price P_n.

As shown in FIG. 1, the computer system 13 may further include a second logical device 15 configured to determine whether the purchase date T exceeds the expiration date T_n. In addition, a real-time price management system of the present invention may further include a warning device electrically connected to the second logical device 15 of the computer system 13, and when the purchase date T is determined exceeding the expiration date T_n, the warning device may send an expiration warning which may be displayed on the display device 16 to remind consumer of the information pertaining to the expiration date of the merchandise.
