For the electronic lottery method, please refer to the excerpt below from the "Kanagawa Electronic Bidding Joint System (Manual)". Note: The successful bidder in the box above should be read as the 1st ranked successful bid candidate. 2. In ② above, the number obtained by adding 2 to the remainder (in the blue box) will be the 2nd ranked successful bid candidate, and by adding 3, the 3rd ranked successful bid candidate, and so on, the order of all lottery participants will be determined. If the sum of the remainder and the added number exceeds the number of participating companies for the 2nd ranked successful bid candidate and subsequent candidates, the number will be the result of subtracting the number of participating companies from that sum. The results of the lottery will be sent along with the successful bid determination notice. 3.

This process will be repeated from 3 and 4 until a candidate is confirmed to meet the competitive participation qualification requirements. Electronic Lottery: In the Kanagawa Electronic Bidding Joint System, when a lottery is necessary as a result of bid opening, an electronic lottery can be conducted based on the lottery number entered in the bid form. The mechanism of the electronic lottery is as follows. ① Participants in the lottery will be sorted in ascending order by lottery number, and a "rank number" will be assigned. (If lottery numbers are the same, the order of bid submission will be used.) ② The number obtained by adding the millisecond value "y" of the date and time when the ordering party presses the "Lottery Determination Button" to the total value "x" of the lottery numbers, and dividing by the number of lottery participants "z", and adding 1 to the remainder, will be the "Winning Number". Calculation Formula: (x + y) / z = m ... n Winning Number = n + 1 (Example) If x = 16, y = 250, z = 3 (16 + 250) / 3 = 88 remainder 2 Winning Number = 2 + 1 = 3 Note: ③ The company whose "rank number" matches the "Winning Number" will be the "Winner = Successful Bidder". *Even if the same lottery number is entered, only one successful bidder will be selected.
