So far, we received 4 solutions for the June-2017 Challenge.  During DecisionCAMP-2017 a lot of people expressed their eagerness to see the voting results. Based on requests from practitioners, we decided to give people more time to prepare and submit their solutions. Please submit your solutions until the August 31, 2017. Then we will hold an online vote by members of DMCommunity.org to define the best decision modeling approaches using this commonly known problem and all submitted solutions. Stay tuned!
