This study develops and empirically validates an integrated conceptual model that investigates the causal relationships among Total Productive Maintenance (TPM), Jidoka, and economic sustainability (ECSU) within the manufacturing industry. Based on Resource and Capability Theory as well as Systems Theory, the model posits that TPM directly influences both jidoka and ECSU, while jidoka acts as a mediator in the relationship between TPM and ECSU. Utilizing structural equation modeling (SEM-PLS) and data collected from 357 surveys of the maquiladora industry in Ciudad Juárez, Mexico, the analysis confirms that TPM positively affects jidoka (β=,632, p<0,001) and ECSU (β=0,340, p<0,001). Furthermore, jidoka contributes significantly to ECSU (β=0,358, p<0,001) and mediates the effect of TPM on ECSU (β=0,226), resulting in an increased total effect of β=0,566. The researchers con...

En este estudio se aplicó la versión en castellano del InventarioSueco de Fatiga Ocupacional (Swedish  Occupational Fatigue Inventory-Spanish), con el objetivo de identificar los síntomas de fatiga en operadores de maquinaria semiautomatizada clasificada como tecnología de manufactura avanzada (TMA). Se encuestaron 121 operadores de tornos de control numérico computarizado (CNC) en una empresa fabricante de flechas homocinéticas localizada en la ciudad de Celaya, Guanajuato, en el centro de México. Los resultados muestran que el factor falta de energía se relaciona con un nivel más alto de fatiga, mientras que el factor somnolencia se relacionó con un nivel más bajo de fatiga.

This article presents a case of a company dedicated to the sale, installation, and service of air conditioning and heating. The company has no internal inventory control in its warehouses. In the period 2022-2023, a total of 3 043 problems related to warehouse management were recorded, with an average of 84,53 problems/month. These deficiencies have led to economic setbacks, project delays, inadequate delivery times and the impossibility of guaranteeing their quality certification objectives in the short term. The objective of this study is to reduce these problems. As a methodology, lean manufacturing tools such as 5S, kaizen and kanban are implemented. After the implementation of the improvement, the problems in the warehouses were reduced to 79, with an average of 26,3 problems/month by the end of June and beginning of November 2023. It is concluded that the application of lean manufa...
