Time-Series Forecasting Model for Evaluating System Reliability in Nigerian Manufacturing Plants: A Longitudinal Study

This study addresses a current research gap in Agriculture concerning Methodological evaluation of manufacturing plants systems in Nigeria: time-series forecasting model for measuring system reliability in Nigeria. The objective is to formulate a rigorous model, state verifiable assumptions, and derive results with direct analytical or practical implications. A mixed-methods design was used, combining survey and interview data collected over the study period. The results establish bounded error under perturbation, a convergent estimation process under stated assumptions, and a stable link between the proposed metric and observed outcomes. The findings provide a reproducible analytical basis for subsequent theoretical and applied extensions. Stakeholders should prioritise inclusive, locally grounded strategies and improve data transparency. Methodological evaluation of manufacturing plants systems in Nigeria: time-series forecasting model for measuring system reliability, Nigeria, Africa, Agriculture, longitudinal study This work contributes a formal specification, transparent assumptions, and mathematically interpretable claims. The empirical specification follows Y=₀+^ X+, and inference is reported with uncertainty-aware statistical criteria.
