Limitations to D/L Method
LIMITATIONS TO DUCKWORTH LEWIS
METHOD
Ravi Agarwal
Abstract-The Duckworth Lewis method, or D/L method, was created by Frank Duckworth and Tony
Lewis. The International Cricket Council (ICC) adopted D/L method in 1999 to address the issue of delayed one-day cricket matches due to interruptions such as inclement weather conditions, poor light and floodlight failures, and crowd problems. This paper deals with the evaluation of the Duckworth Lewis method, identifying its limitation, and devising a modification to address these limitations.
Index Terms- Duckworth Lewis, Rain rules,
Statistics, VJD Method
1 INTRODUCTION
The use of mathematical models in sport in general and cricket in particular has been growing in recent years.The D/L method or Duckworth Lewis method, was adopted by the International Cricket Council
(ICC) in 1999 to address the issue of delayed one-day cricket matches due to bad weather(rain, snowstorms and sandstorms), poor light and floodlight failures, and crowd problems[2]. The Duckworth Lewis
Method, a system based on a mathematical model considering only two resources -- wickets left and overs remaining -- has been applied successfully in the one day cricket matches to address the issue of interruptions such as those due to bad weather conditions. The earlier “rain rules” methods to handle interruptions in cricket matches suffered from certain disadvantages like favoring the team batting second.
The Duckworth Lewis method eliminates such problems and is known for its comprehensibility, simplicity and ease calculate the target runs.
However, certain factors such as the toss may play a crucial role in deciding the winner of the match since it involves a lot of thought and research while taking a decision after winning the toss. Certain other factors such as batting first play an important role especially in rain affected cricket matches. After rain, the pitch becomes soft and the ball bounces more
