Abstract

The increasing competitive pressure in manufacturing industries necessitates the adoption of cost-efficient and waste-minimizing production strategies. This study develops a lean-based optimization framework integrating Just-in-Time (JIT) principles to enhance cost efficiency in the preparation processes of four-wheel tractor manufacturing. The research synthesizes lean manufacturing theories and empirical insights from prior studies to construct a structured model aimed at minimizing inventory costs, reducing process inefficiencies, and improving production flow. A mixed-method analytical approach is adopted, combining conceptual modeling with process optimization techniques. The findings indicate that integrating JIT with lean tools such as waste identification, process mapping, and continuous improvement significantly reduces operational costs and enhances production responsiveness. The study contributes to the theoretical advancement of lean-JIT integration and provides practical implications for manufacturing firms seeking to optimize pre-production activities.
