The purpose of this paper is to develop a deterministic model for setting the target in T-20 Cricket by the team batting first. Mathematical tools were used in model development. Recursive function and secondary data statistics of T-20 cash rich cricket tournament Indian Premier League (IPL) such as runs scored in different stages, fall wickets in different stages, and type of pitch are used in developing the model. This model was tested at 120 matches held IPL 2016 and 2017. This model had been proved effective by comparing with the models developed earlier. This model can be a useful tool to the stakeholders like coach and captain of the team for adopting better strategy at any stage of the match. For future research, this model can be useful in framing a regulation work by policy makers at both national and international cricket board by deriving the target score during interruptions.

This may be due to the fact that there may exist uncertainty in Cricket is one of the most popular sports in the setting a right target for the team batting second. The world. Mostly this game is played in commonwealth team batting first will try to score as many runs as countries as it is originated in UK. It is a game possible in their 20 overs in order to set a target. The played between two teams of eleven players each. team batting second has an advantage of knowing With the advent of optimal modeling in sports, the exact target and of course their strengths as well setting the target score in T-20 cricket game has been as opposition bowling strengths. They need to chase considered as a challenging problem. The game of the target in order to win the game. For years while cricket is played in three formats – Test Matches, watching limited overs cricket, we have seen pro- ODIs and T20 s. This paper focusses research on T20 jected scores at different intervals being displayed on matches, the most popular format of the game in the television screens.
