Description

  The present invention relates to a date specifying method for specifying a reference date for reference in order to refer to a past product order history in ordering a product, and a date specifying program for causing a computer to execute a date specifying function for specifying a reference date. Further, the present invention relates to a product ordering information processing apparatus that acquires a product order history of a specified reference date from a history database.

  In ordering goods at a store, it is important to place an order for an appropriate amount of goods in order to reduce the amount of waste and reduce the shortage of inventory. Therefore, in the product ordering business, in order to determine the quantity and items of products to be ordered, the past product order history under the same conditions as the order date for ordering products is used as a reference. As an example, Patent Document 1 describes sales in a past corresponding period similar to the period when it is desired to make a prediction, such as commonality of day, month, week, day of week, time, or climate, which is used when determining the order quantity of a product. A sales forecasting device that calculates a sales forecast based on actual results is described (claims 1 and 15 of Patent Document 1).

  As described in Patent Document 1, when referring to a past product ordering history in a product ordering operation, it is important to refer to a product ordering history on a date under the same conditions as possible with respect to the ordering date. Therefore, it is effective to adopt a past day that is the same day of the same month as the reference date and changes only the number of years as a reference date for reference of the product order history. In particular, “same day of the previous year”, which is about the same year as the order day and the same day of the same month, is often used to refer to the product order history.

  However, the year is 365 days (366 days if it is a leap year), and since it is not divisible by 7 days constituting a week, the date of the order date may not match the date of the reference date. Therefore, a day before the order date, which is the same week of the same month as the order date, may not be appropriate as the reference date.

  For example, consider a case in which the same day of the previous year as of January 9, 2007 (the day before the order date and the same week of the same month) is used as the reference date. January 9, 2007 is Tuesday of the first week in January 2007, when Sunday has passed once. The day before the order date is January 3, 2006, which satisfies the condition “January, Sunday, 1st week, 1st Tuesday, Tuesday”. That is, January 3, 2006 is set as a reference date for the order date (January 9, 2007). However, there is a difference of 6 days between the date of ordering date and the date of reference date. In this case, it is the same day as the order date (January 9, 2007) and a different week from the product order history on the reference date (January 3, 2006) with respect to the order date (January 9, 2007). It can be said that the product order history of January 10, 2006 is a reference for product orders. As described above, the day of the same week of the same month in the past with respect to the order date may not be preferable for the reference date of the product order history.

  An object of the present invention is to set a preferred reference date for an order date with respect to a past product order history used as a reference when placing a product order.

  An embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a schematic diagram of the entire product ordering system 100. The product ordering system 100 according to the present embodiment is configured such that a server device 101 as a history server and a client device 201 as an information processing device for product ordering are connected via a public line network 301 so as to be able to perform data communication. .

  The server device 101 is a server for constructing a so-called server client system, and is installed in the headquarters 51. The server apparatus 101 can access the history database 151 and the date attribute database 152 as a date attribute storage unit. The history database 151 stores the order contents in the product ordering work transmitted from each store 52 to the head office 51 as the product order history in association with the date and the store code for specifying the store. The product order history is composed of various product order information such as a product code for specifying a product and the number of orders for each product. The date attribute database 152 stores a date and an attribute of the date in association with each other. The date attribute database 152 will be described later with reference to FIG.

  The client device 201 is a desktop personal computer and is installed in the store 52. The client device 201 includes a display device 207 as a display unit for displaying information and an input device 208 as an input unit for inputting information, and is connected to an in-store network 55 configured in the store 52.

  In the store 52, a plurality of POS registers 53 including the client device 201, a drawer 53a, and a POS terminal 53a that executes product sales data processing mounted thereon, and the devices in the store 52 are managed in an integrated manner. The store controller 54 is connected to each other via a store network 55 so as to be able to communicate with each other, and constitutes a LAN (Local Area Network). The client device 201 and the store controller 54 have a communication function, and can perform data communication with the server device 101 via the in-store network 55 and the public line network 301.

  In the product ordering system 100 configured as described above, product ordering is performed at each store 52. The client device 201 installed in each store 52 is installed with a program for sending product order contents to the server device 101 and placing a product order. The store clerk operates the client device 201 to implement the product order. Is done.

  In the product ordering system 100 of the present embodiment, product ordering information input from the client device 201 is transmitted to the server device 101. The server apparatus 101 performs an ordering process to be transmitted to each wholesaler and each trading company based on the received product ordering information in accordance with the contents of the program stored in the HDD 105 (see FIG. 2). The information is registered in the history database 151 as a product order history in association with the order date and the store code of the store 52 where the order was placed.

  Further, in the product ordering system 100 according to the present embodiment, the sales orderer who operates the client apparatus 201 to place a product order shows the product order history on the reference date corresponding to the order date acquired from the history database 151 and orders the product. Provide assistance in determining content.

  That is, when the client apparatus 201 transmits a request command for requesting a merchandise order history to the server apparatus 101 installed in the headquarters 51, the client apparatus 201 specifies which date the merchandise order history is acquired in the past. The reference date that should be referred to is also sent. The reference date is basically set to the same day of the same month in the same month before the order date relative to the order date for placing the product order. However, if the reference date is not included in the predetermined allowable period including the order date, the display device 207 provided in the client apparatus 201 displays a list indicating the periods before and after the reference date (see FIG. 6) or a message prompting the user to select one day from the displayed period. When the clerk inputs a date to be used as a reference date from the input device 208 in accordance with the instruction displayed on the display device 207, the client device 201 sets the input date as a reference date. The client apparatus 201 transmits a request command for requesting the client apparatus 201 to transmit the commodity order history of the set reference date to the client apparatus 201, and receives the commodity sales history of the reference date transmitted from the server apparatus 101. stand by. When receiving the merchandise sales history of the reference date transmitted from the server apparatus 101, the client apparatus 201 displays the received merchandise order history on the display device 207 or applies it to a merchandise ordering system (not shown) that determines the merchandise order quantity. Or

  Note that the client device 201 displays a list on the display device 207 if the date attribute (see FIG. 4) differs between the order date and the reference date even if the reference date is included in the allowable period. The date input from the input device 208 is set as a reference date.

  The above process is realized by a product order history acquisition process executed by the CPU 203 of the client device 201. The flow of the product order history acquisition process will be described later with reference to FIG.

  FIG. 2 is a block diagram illustrating a hardware configuration of the server apparatus 101. The server apparatus 101 includes a microcomputer 109 serving as a first information processing unit. The microcomputer 109 is mainly configured by a CPU 102 that executes various arithmetic processes and controls each unit.

  FIG. 4 is a schematic diagram showing the data structure of the date attribute database 152. The date attribute database 152 is a database that stores the date attribute 152c and the date name 152d in association with the year 152a and the date 152b from January 1st to December 31st.

  The date attribute 152c indicates whether the date determined by the year 152a and the date 152b is a legal holiday, a quasi-holiday uniquely determined by the headquarters 51 as a holiday, or a normal day other than a holiday or quasi-holiday Is stored in the date attribute database 152 in the form of code data. As a semi-holiday, for example, a day corresponding to New Year's 3rd, including New Year's Day, Golden Week, or Bon Festival can be adopted. The date attribute 152 c stored in the date attribute database 152 can be changed by processing executed by the CPU 203 realized by a program stored in the HDD 206.

  The date name 152d is a name indicating what kind of date is the year, month, and day determined by the year 152a and the month 152b, and is stored in the date attribute database 152 in the form of text data. The date name 152d is, for example, “New Year's Day” for January 1, “New Year 3 is Sunday” for January 2, and January 3.

  FIG. 5 is a flowchart showing a flow of product order history acquisition processing executed by the CPU 203 of the client device 201. The CPU 203 of the client device 201 executes a product order history acquisition process described below in accordance with the description of the program stored in the HDD 206.

The CPU 203 of the client device 201 starts the product order history acquisition process when the order date and the past year (reference year) referring to the product order history are input from the input device 208. That is, the input of the order date and the reference year triggers the start of the product order history acquisition process. Here, the _{Y 1} year _{M 1} January _{D 1} day as order date from the input device 208 is input. Further, in the designation of the reference year, it is assumed that the input is designated so as to refer to the merchandise order history on the reference date x years ago.

When starting the product order history acquisition process, the CPU 203 of the client device 201 first specifies the day-of-week specifying information _wd1 for specifying what day the input order date is and the week of the order date. Week specific information _wn1 is obtained (step S101). That, CPU 203, _{when Y 1} year _{M 1} January _{D 1} day as order date is _input, Y 1, _{M 1} and _{D 1,} Zeller's congruence h = y + [y / 4 ] - [y / 100] + [Y / 400] + [(13m + 8) / 5] + d (mod 7)
(However, y: year, m: month, d: day, []: floor function. When m = 1 or m = 2, (y-1) is replaced with y instead of ( m + 12) is used.)
And the numerical value h is calculated, and the numerical value h is adopted as the day-of-week specifying information _wd1 . In addition, h calculated as a result of applying the Zeller formula is an integer value of 0 to 6, h = 0 is Sunday, h = 1 is Monday, h = 2 is Tuesday, h = 3 Corresponds to Wednesday, h = 4 corresponds to Thursday, h = 5 corresponds to Friday, and h = 6 corresponds to Saturday. In addition, CPU203 is, appeared Sunday (h = 0) to apply the official Zeller in each day of the period from _{January 1, Y 1} year _M to ₁ year _{M January D 1} day _Y, is included in this period The number of times is counted, and this number of times of count is adopted as the week specifying information _wn1 .

For example, the day specifying information _wd1 on January 9, 2007 (Tuesday) is 2, and the week specifying information _wn1 on January 9, 2007 (Tuesday) is also 1.

As a subsequent process, the CPU 203 of the client device 201 calculates a reference date in the reference year input from the input device 208 (step S102). That, CPU 203, _{first, (Y} 1 -x) calculating the day of the week specified information _{w d2} and weekly specific information _{w n2} year _{M 1} January, followed by weekly specific information _{w d1} and day calculated in Step S101 using specific information _{w n1,} than the _{Y 2-year M 1} January _- the _{((w n1 + 7w d1)} (w n2 + 7w d2)) days after the _{Y 2-year M 2} may _{D 2} days is calculated as the reference date.

For example, when calculating the same day of the same month the same week before the order date (so-called the same day of the previous year) as a reference date for the order date January 9, 2007 (Tuesday), the CPU 203 calculates (2007-1) year. Applying Zeller's formula for January 9, calculate day-of-week specific information w _d2 = 0 and week-specific information w _n2 = 1. Then, using the day of the week specific information _{w d1} = 2 and _{w n1} = 1 for the order date January 9, 2007, as a _{two-year M 2} May _{D 2} days _Y, January 1 (2007-1) years January (2006), which is ((2 + 7 × 1) − (0 + 7 × 1)) days later, is calculated as a reference date.

As subsequent processing, CPU 203 of the client apparatus 201, _{M 2} May _{D 2} days a month of the calculated reference date in step S102 is a predetermined around the _{M 1} January _{D 1} day a month of order date It is determined whether it is included in the allowable period (step S103). This allowable period is defined based on conditions stored in a storage unit such as the ROM 204 or the RAM 205. For example, the allowable period is defined during the period from 3 days before the _{January D 1} day _M until after 4 days of _{M January D 1} day.

If the processing in step S103 _{M 2} May _{D 2} days is determined not included in this allowable time (N in step S103), the CPU203 of the client device 201 shifts the processing to step S107 (described later).

In contrast, when it is determined that _{M 2} May _{D 2} days is included in the allowable period in the process in the step S103 (Y in step S103), as CPU203 continues processing of the client apparatus 201, order date to the server device 101 _{(Y 1} year _{M 1} January _{D 1} day) and the reference date _{(Y 2} years _{M 2} May _{D 1} day) to get each of the date attribute 152c and date name 152d of the (step S104). More specifically, the CPU 203 of the client apparatus 201 transmits the order date and the reference date to the server apparatus 101, and receives the date attribute 152c and the date name 152d of each of the order date and the reference date transmitted from the server apparatus 101. Waiting. When the CPU 102 of the server apparatus 101 receives the order date and the reference date transmitted from the client apparatus 201, the CPU 102 inquires the date attribute database 152 to acquire the date attribute 152c and the date name 152d for the order date and the reference date, and acquires the client name. Transmit to the device 201. When receiving the date attribute 152c and the date name 152d transmitted from the server apparatus 101, the CPU 203 of the client apparatus 201 determines whether the date attribute 152c of the order date and the date attribute 152c of the reference date are the same as subsequent processing. Is determined (step S105). In the process in step S105, when it is determined that the date attribute 152c of the order date and the date attribute 152c of the reference date are the same (Y in step S105), the CPU 203 of the client device 201 moves the process to step S110. On the other hand, when it is determined in the process in step S105 that the date attribute 152c of the order date is different from the date attribute 152c of the reference date (N in step S105), the CPU 203 of the client device 201 moves the process to step S107. .

As processing subsequent to N in step S103 or N in step S105, the CPU 203 of the client device 201 displays a list of dates for a predetermined period including the reference date on the display device 207 (step S107). That, CPU 203 of the client apparatus 201, if the date of the reference date calculated at step S102 _{(M 2} February _{D 2} days) is not included in the allowable period including the date of order date _{(M 1} January _{D 1} day) Alternatively, if the date attribute 152c of the order date is different from the date attribute 152c of the reference date even if the date of the reference date is an allowable period including the date of the order date, the process shown in step S107 is performed.

  FIG. 6 is a schematic diagram illustrating an example of a display screen 401 displayed on the display device 207 by the CPU 203 of the client device 201. FIG. 6 shows an example of a screen display that prompts the store clerk facing the display device 207 to select the same day of the same week the same month of the previous year as of January 9, 2007 (the same day of the previous year).

  The CPU 203 of the client device 201 displays a display screen 401 as shown in FIG. 6 on the display device 207 in the process executed in step S107. The display screen 401 includes a central date list 402 arranged at the center of the display screen 401, a message unit 403 arranged above the display screen 401 and prompting a store clerk facing the display device 207, and below the display screen 401 And a footnote unit 404 that supplements the explanation on the display screen 401.

  The date list 402 is a table composed of two columns of fields including a date field 402a and a date name field 402c. The date list 402 includes a reference date 402d (January 3 (Tuesday) in FIG. 6) corresponding to the order date, and a date for about two weeks (December 27 (Tuesday in FIG. 6). ) To January 10 (Tue)) are displayed in the date field 402a, and the date name corresponding to each date is displayed in the date name field 402c. The date name displayed in the date name field 402c is the date name 152d stored in the date attribute database 152 accessible by the server apparatus 101. The CPU 203 of the client apparatus 201 transmits a request command for requesting the server apparatus 101 to acquire the date name 152d to be displayed in the date field 402a and transmit it to the client apparatus 201, and then transmits the date transmitted from the server apparatus 101. The date name 152d is acquired by receiving the name 152d.

  The message unit 403 is a text display that displays a message for urging the store clerk facing the display device 207 to select one day as a reference day from the periods displayed in the date list 402. In the example shown in FIG. 6, in order to make the store clerk select the same day of the previous year as of January 9, 2007, the message section 403 displays “candidate of the same day of the previous year on Tuesday, January 9th. Please select (touch). ”Is displayed.

  The footnote unit 404 is additional information for a store clerk facing the display device 207. In the example shown in FIG. 6, since the reference date calculated in the process so far is January 3, 2006, the current candidate date January 3 is registered as “New Year 3 is Sunday” in the footnote section 404. It is. Is displayed.

  Returning to the description based on FIG. As processing subsequent to the processing shown in step S107, the CPU 203 of the client device 201 waits for input of a date to be used as a reference date from the input device 208 (step S108). The date input from the input device 208 is performed by keyboard input or by touch designation from a touch panel arranged on the pointing device and the display device 207. When a date to be used as a reference date is input from the input device 208 (Y in step S108), the CPU 203 of the client device 201 applies the date input from the input device 208 as a reference date to be used as a reference for the product order history. (Step S109).

  As a subsequent process, the CPU 203 of the client device 201 transmits a request command for requesting the server device 101 to transmit a merchandise sales history corresponding to the reference date together with the reference date calculated in step S102 or the reference date applied in step S109. Then, the product order history of the reference date transmitted from the server device 101 is received, the product order history of the reference date is acquired, and the product order history acquisition process is terminated (step S110). When the CPU 102 of the server apparatus 101 receives the reference date transmitted from the client apparatus 201, the CPU 102 inquires the history database 151 to acquire the product sales history corresponding to the reference date and transmits it to the client apparatus 201.

  FIG. 7 is an explanatory diagram showing a specific example of the process of setting a reference date for the order date in the product ordering system 100. Hereinafter, a process of identifying a reference date for an order date in the product order system 100 will be described based on a specific example shown in FIG. In these examples, the permissible period that is a criterion for determining whether or not the reference date corresponds to the order date is defined as a period from 3 days before to 4 days after the order date To do.

1. Process of setting a reference date two years before the order date February 21, 2007 (case.1)
The CPU 203 of the client apparatus 201 executes the process of step S101 of the merchandise order history acquisition process (see FIG. 5), and the order date February 21, 2007 has passed the Sunday in February 2007 three times. Specify that it is Wednesday of the week. Subsequently, the CPU 203 of the client apparatus 201 executes the process of step S102, and is the third week of Wednesday 2005, which is three times past the Sunday of February 2005, which is two years before February 2007. February 23 is calculated as a reference date. February 23, which is the date of this reference date, is included in the allowable period (February 18 to February 25) centered on February 21, which is the order date, and the order date. Since the date attribute of both the reference date and the reference date is a normal date, the CPU 203 of the client device 201 proceeds with the product order history acquisition processing in the order of Y in step S103, S104, and Y in step S105. The product order history as of February 23, 2005) is acquired from the history database 151.

2. The process of setting the reference date two years before the order date February 9, 2007 (case.2)
