Abstract:
In limited-overs cricket, rain interruptions require adjustment of the target score for the chasing team. The Duckworth-Lewis-Stern (DLS) method is widely used for this purpose but does not explicitly include factors such as pitch condition, dew accumulation, or player strength. To address this limitation, we propose a Fuzzy-DLS model that includes fuzzy logic into a generalized resource function. The method allows batting quality index (BQI), bowling threat index (BTI), pitch state, and weather effects to adjust the resource curve in a continuous and interpretable way. For the 30 illustrative cases in Appendix A, the proposed formulation differs from the DLS resources by a mean absolute amount of 0.0152, with a mean relative difference of [Formula: see text] and a mean absolute par-score difference of 2.13 runs. In the 100-match ODI sample analysed here, chasing teams won [Formula: see text] of winter matches compared with [Formula: see text] in non-winter matches, giving an odds ratio of 2.21 and a chi-square p-value of 0.081. These results support the use of fuzzy match-condition inputs transparently.

Accuracy is defined as the closeness of the measured value to the true or actual value. In engineering mechanics, repeated measurements are taken during theoretical or experimental analyses to ensure that the result is precise and accurate.
