Resumen

Companies that rely on equipment-based services require high operational continuity; however, small maintenance workshops commonly lack standardized procedures, generating variability, delays, and unproductive time. Existing maintenance and inventory models are often designed for large-scale or highly formalized organizations, limiting their applicability to small service environments characterized by informality and reliance on individual expertise. This study proposes an engineering-based operational model specifically tailored to small maintenance workshops, integrating process standardization with inventory management using reorder point and EOQ. The approach was validated through discrete-event simulation in Arena. Results show an improvement in service level from 34.76% to 75.33%, a reduction of stockouts to 3.49%, and greater task consistency. By integrating these techniques, small maintenance workshops can mitigate operational disadvantages and achieve service performance levels comparable to those of larger, highly formalized service organizations.
