C 2020赛制
为适应中华区校历的地区多样性，中华区域赛将开启秋季和冬季两个赛季，参赛团队可自由选择参加其中一季或两季竞赛，以最佳成绩参加中华区2020年度总评选及晋级国际赛。
IM
2
C鼓励学科交叉与综合创新，提倡团队成员发挥多元优势，提倡指导教师来自包括数学在内的STEM跨学科背景。国际数学建模挑战赛每支参赛团队须由来自同一所中学的2-4名同学组成，且须有来自该校的至少1位教师担任指导老师。来自世界各地的参赛团队经过国家/区域赛的选拔，进入国际赛程；在国家/区域与国际层面，皆有机会获取各级奖项。
中华区域赛参赛团队可自行选择以“命题论文”参赛，亦可选择以“自主选题论文”参赛。“命题论文”须在连续的96小时之内完成并提交，“自主选题论文”不限开始时间，惟须在赛季截止时间前提交。具体而言，选择以“命题论文”方式参赛，团队自秋季赛2019年11月21日（星期四）晚8时（GMT/UTC+8时区）开始，或者冬季赛2020年1月16日（星期四）晚8时（GMT/UTC+8时区）开始，根据中华专家组的命题，在连续的96小时内，完成并提交一篇数学建模论文；选择以“自主选题”(必须是现实世界问题)方式参赛，则自主决定论文工作的开始时间和进度，但必须在中华区秋季赛或冬季赛截止时间 ——2019年11月25日（星期一）晚8时（GMT/UTC+8时区）或者2020年1月20日（星期一）晚8时（GMT/UTC+8时区）之前完成并提交一篇自主选题的数学建模论文。在随后的专家评审中，命题论文与自主选题论文将分开评审，两类论文中成绩进入首20%的团队，将自动获得晋级国际赛程的机会。
IM
2
C 2020中华赛区国际赛程将在2020年3月10日(星期二)晚8时—3月15日（星期日）晚8时之间进行，国际赛程的参赛团队须在此120小时之内，就IM
2
C国际专家组命制的问题，完成并提交一篇数学建模论文。在刚刚过去的2019年度，IM
2
C国际赛程参赛队伍来自逾30个国家和地区。
答辩决赛
入围中华区域赛程答辩决赛与国际赛程答辩决赛的团队将获得主办机构的邀请，于2020年4月24-25日莅临香港/大湾区城市，做论文演示与答辩。大评审团将分别对中华区域赛程与国际赛程的决赛团队进行评审。
IM
2
C中华委员会还将从中国大陆、台湾、香港及澳门进入国际赛程论文答辩的队伍中，各评选两篇最佳论文（中华区共八篇），推举进入国际评审（其他参赛国或地区亦各遴选两篇最佳论文进入国际评审）。
评奖与颁奖
中华区各参赛团队将有机会以中华赛论文或国际赛论文的评审结果，获取中华区各级奖项。每支参赛团队的获奖机会都将是平等的。中华赛命题论文、自选题论文与国际赛论文将分类评奖，你的团队无论是凭中华赛命题论文，或者自选题论文，还是国际赛题论文，都将有机会去竞争中华区域各大奖项。
IM
2
C 2020中华峰会暨数学建模教学夏季工作坊将于2020年夏季举行。这将是中华区中学师生为主角的高规格学术盛会, IM
2

An Invitation to Secondary School Students in
the Greater China Region
For the 6th Annual International Mathematical Modelling Challenge（IM
2
C 2020）
We warmly invite secondary school students from Mainland China, Taiwan, Hong Kong and Macau to participate in the 5th Annual International Mathematical Modeling Challenge- IM
2
C 2020. The
registration
for the Greater China Regional contest has started. Let’s join our hands together and pursue a journey of creation and discovery in the coming season.
International Mathematical Modeling Challenge (IMMC or styled as IM
2
C) is an innovative contest in mathematical modeling for secondary school students all over the world. The aim of IM
2
C is to promote mathematical modeling education and enhance students’ core competencies in mathematics and innovation, encouraging participants to explore the application of mathematical modeling in real life situations to solve problems of importance. IM
2
C in this Region is an inclusive and sharing platform both for secondary school students to practice mathematical modeling, and for schools to demonstrate and exchange their educational accomplishments in mathematics and STEM.
IM
2
C in Greater China Region is an interdisciplinary practice integrating mathematics with science, technology and engineering which reflects the essence of STEM education. The co-founder of IM
2
C NeoUnion ESC Organization works with the Institute of Electrical and Electronics Engineers (IEEE China) and Hong Kong Society for Industrial and Applied Mathematics to co-organize the IM
2
C 2020 in Greater China. The Problem Setting Committee and the Judging Panel consist of experts and professors from IM
2
C Committee (Zhonghua) and IEEE whose disciplinary fields cover mathematics, science, technology, and engineering. Prof Raymond Chan, Dean of School of Science of City University of Hong Kong and Fellow and Council Member of Society for Industrial and Applied Mathematics (SIAM, US) will chair the Committee of IM
2
C 2020 Greather China; Prof Yang WANG, a member of IM
2
C International Expert Panel, Dean and Chair Professor of School of Science at The Hong Kong University of Science and Technology acts as Chairman of the Problem Setting Committee and Grand Jury of the Final Presentation Competition of IM
2
C 2020 Greater China.
IM
2
C 2020 and its Rules
To cater for the diversity in school calendar across the Region, two seasonal contests, namely Autumn and Winter Contest, will be open for IM
2
C 2020. Teams may choose one of the seasonal contests according to their schedule to compete for the yearly awards in the region of Greater China and qualification to proceed to the international round.
IM
2
C encourages interdisciplinary innovation and teamwork for students and teachers. IM
2
C requires each team to be composed of 2-4 students from the same secondary school, and at least one teacher from the same school to serve as team advisor. Participating teams from all over the world will be selected by a national/regional selection process before they enter into the international round of IM
2
C. For both the national/regional and the international round of competition, winning teams will be recognized as different levels of awards.
Participating teams from Greater China region can choose: 1) to work on a problem created by the Problem Setting Committee of IM
2
C Greater China starting from 8:00 pm on November 21st (Thu) 2019 (GMT/UTC+8 hours), Autumn Contest, or January 16th (Thu) 2020 (GMT/UTC+8 hours), Winter Contest. During the following consecutive period of 96 hours, teams must complete and submit a solution paper of mathematical modeling; 2) alternatively, register for a self-challenging problem, i.e., the team can choose freely a problem set by the team members themselves. Note that such problem must be a real-world problem discovered and identified by the team. To work on the freely-chosen problem, teams can decide on their own about the starting time and schedule; however, they must complete and submit their solution paper of modeling on or before 8:00 pm November 25th (Mon) 2019 (GMT/UTC+8 hours), or January 20th (Mon) 2020 (GMT/UTC+8 hours), deadline of the seasonal contest in Greater China. Solution papers of the two categories will be judged separately. Teams whose papers are judged as among the top 20% of the two categories of papers respectively will automatically proceed to the International Round of IM
2
C 2020.
IM
2
C 2020 International Round in the Greater China Region will start at 8:00 pm March 10th (Tue) 2020 (GMT/UTC+8 hours), and end at 8:00 pm March 15th (Sun) 2020 (GMT/UTC+8 hours). Within a consecutive period of 120 hours, teams entering the IM
2
C international round will work on the problem set by the International Expert Panel, complete and submit their solution paper on or before the end of the contest period. Teams from over 30 countries and regions will be selected by their country/region to enter IM
2
C 2020 International Round.
Final Presentation Competition
The finalist teams of IM
2
C 2020, both for the Greater China Regional and the International rounds, will receive invitation from the IM
2
C Committee to come to Hong Kongi/Greater Bay city April 24-25, 2019, and attend the Final Presentation Competition, presenting and defending their works in front of the Grand Jury.
IM
2
C Committee Greater China will also select the best two papers from each of the Mainland, Taiwan, Hong Kong and Macau finalists in the International Round (totally 8 papers) for recommendation to the International Expert Panel. (Each participating country or region will select the best two papers for the International Panel’s Judgement.)
Recognition and Award Ceremony
The participating teams from Greater China Region will have the equal chances to be recognized with different awards at both regional and international levels. The papers will be judged as per categories of Greater-China-Committee-set problem, freely-chosen problem, and International-Expert-Panel-set problem, respectively. Each participating team, no matter whether or not they are selected into the International Round, will have the chances to compete for the awards of the Greater China Region.
An IM
2
C 2020 Greater China Summit cum Summer Workshop and Award Ceremony will be held in the summer of 2020. This will be a prestigious academic conference of the Region for secondary school students and teachers exclusively. Teams winning the Outstanding Award of the Regional and/or International contests will be invited to deliver plenary speeches at the Summit. Members of IM
2
C Committee and the Problems Setting Committee along with renowned experts in relevant fields will also be present, so as to interact and exchange with the secondary school students and teachers. Winning teams of the International Outstanding Award or Global Top 5 teams will be invited to attend the themetic activities and award ceremony on The 14th International Conference on Mathematics Educaiton to be held in Shanghai (
