The issue, forecast preparation of elements in routine maintenance, is to predict daily consumptions of the shared item groups within laptops. Maintenance records of applied materials and sales records of products would be used as the base to predict future consumptions. Considering the time spent from purchasing materials globally to delivering materials to maintenance base, we have daily forecast preparation offer to predict the weekly consumptions in the next 21 weeks, which enalbes customer service unit to purchase and operate transportations of elements. How to predict the consumption precisely has become a vital issue to lower the cost. This issue is for acedemia to participate only, and are welcome to lower the preparation costs by exploring future consumptions of shared items through data science.
This is an open-ended problem that can be solved consistently over a long period of time, and has offered milestone awards for participants. the award will be given to the first three participants who reached the Baseline(MAPE<40), and Private Leaderboard will be updated occasionally.
After the milestone is ended, date set will be updated(around October), and the scores (includes individual ones and the ranking) will be cleared.
MAPE < 20 300,000 discount points of hicloud
MAPE < 30 200,000 discount points of hicloud
MAPE < 40 100,000 discount points of hicloud

This milestone will start at 12:00 PM Taiwan Standard Time (UTC+8) on 28/08/19(DD/MM/YY), and end at 11:59 PM on 30/09/19(DD/MM/YY). The result will be announced on 01/10/19(DD/MM/YY)，and the award will be given based on the result.
Before milestone ended, the Private Leaderboard will be updated every two weeks.
After the participants prepare the forcasts of the shared item group, the back-end of the system would process them in bathces regularly to calculate the score. Evaluations are conducted by calculating the mean absolute percentage error (MAPE) of the actual value. The formula is as follows,
$$ MAPE = \frac{100}{n} \; {\sum_{i=1}^{n}} \; { \biggr\lvert \frac{ y_i - \hat{y}_i }{y_i} \biggr\rvert } $$
