- Annotation: For simulation-based analysis of cotton fibre length measurement using a fibrograph under the HVI method, an efficient algorithm for generating realistic fibre length distributions is required. It has been established that a right-skewed normal distribution law provides an adequate basis for such modelling. The necessity of improving the known algorithm, which relies on difficult-to-interpret distribution parameters (location ξ, scale ω, and shape α), is emphasised. The proposed refinement consists in replacing these parameters with widely accepted statistical characteristics of fibre assemblies – the mathematical expectation M, the mode Mo, and the standard deviation σ of fibre length. An algorithm for computing the mode Mo is developed, implemented through a dichotomy method. A comparative analysis was performed between empirical distributions reported in published sources and synthetic distributions obtained via the newly proposed approach. A high degree of similarity was observed, confirming the effectiveness of the developed simulation method based on conventional statistical descriptors (M, Mo, σ).
