Case
Cricket is a bat-and-ball team sport, played by two teams with eleven players on each side. Recently, a new format of cricket called ‘Twenty20’ (T20) was introduced, which has increased the excitement, fan following, and business opportunities in cricket. In 2008, Indian Premier League (IPL) was created with eight city-based franchises. Two more franchises were added in 2010. The focus of this case is on the selection of the playing eleven for the team Kolkata Knight Riders (KKR), the most valued brand name among IPL franchises. Thirty five players were on the KKR team roster in the first two editions of the IPL. Unlike many other sports, the playing eleven cannot be changed in a cricket game once the game starts. The case aims to strengthen students’ ability to mathematically formulate a real life “yes-or-no” type decision. Binary Integer Programming (BIP) is a suitable choice for modeling “yes-or-no” type decisions. The case, if provided with International Cricket Council (ICC) rankings data and in-house point system, will be appropriate for an undergraduate level management science/operations research class. The same case will be suitable at graduate level, if students are expected to gather ICC rankings data and build in-house point system. There are competing constraints that would lead to discussions about infeasibility. The case also points out the importance of interpretation of the solution and user friendliness of the model from an end user’s perspective.
