Abstract: El presente trabajo de investigación consiste en la mejora del área de operaciones a partir
de la implementación de un nuevo sistema de gestión logística en la empresa
TERRAMAQ CONTRATISTAS GENERALES S.A.C con el objetivo de reducir los
elevados costos logísticos y el retraso en avance de la obra de saneamiento ejecutada en
el distrito Ocucaje en el departamento de Ica.
Se demostró una reducción total del 11,67% del tiempo promedio de retraso en
avance de obra, es decir de 14 a 0 días, lo que genera un impacto de S/ 90 679 de ahorro.
Por otro lado, se obtuvo otra reducción total en el costo logístico adicional al
presupuestado del 5,68%, mismo que genera un impacto de S/ 46 019 de ahorro. Más
adelante, se encontró la causa raíz que resultó ser la mala gestión de compras, por lo que
se propusieron alternativas de solución resultando la indicada para hacer la mejora la
implementación de un sistema de gestión de compras programadas.
En primer lugar, mediante el método de clasificación de materiales ABC, se
descubrió que los denominados “Materiales tipo A” (tubos de 250, 200 y 160mm; bolsas
de cemento; y kits de caja y tapa de desagüe) son los principales para hacer el diagnóstico
de gestión logística. Posteriormente, y a partir de la implementación de la mejora
basándose en compras programadas mediante el Plan de Compras MRP, se realizó
simulaciones en el software Arena para los materiales tipo A con el objetivo de comparar
el escenario actual con el implementando tras la mejora (reducción a 0 de los
indicadores), demostrando de esa forma la viabilidad técnica de la mejora.
Seguidamente, se comprobó la viabilidad económica mediante la comparación de
los distintos indicadores resultantes del estado mejorado y actual: VAN (S/ 576 275 Vs
S/ 289 190), TIR (119% Vs 41%), Beneficio Costo (4,35 Vs 1,88) y Periodo de Recupero
(21 días Vs 41 días), tomando una inversión inicial (S/ 171 817 Vs S/ 330 000) y diversos
ingresos y gastos involucrados.
Finalmente, se recurrió a la construcción de indicadores sociales como Valor
agregado (S/ 1 548 602,21), relación producto capital (9,01), productividad de mano de
obra, intensidad de capital (0,11), y densidad de capital (S/ 4 909,05 para todos los meses)
demostrando de esta forma que el proyecto también es viable socialmente.
This research work consists of improving the operations area from the implementation of a new logistics management system in the company TERRAMAQ CONTRATISTAS GENERALES SAC with the aim of reducing the high logistics costs and the delay in progress of sanitation construction carried out in the Ocucaje district in the department of Ica. It was shown a total reduction of 11.67% of the average delay time in progress of the construction, that is from 14 to 0 days, which generates an impact of S/ 90 679 in savings. On the other hand, another total reduction in the logistics cost in addition to the budget of 5,68% is obtained, which generates an impact of S / 46 019 of savings for the company. Later, the root cause was found, which turned out to be poor purchase management, so alternative solutions were proposed, resulting in the right one to improve the implementation of a programmed purchase management system. In the first place, by the ABC materials classification method, it was discovered that the so-called "Type A materials" (250, 200 and 160mm tubes; cement bags; and box and cover drain kits) are the main ones to do the diagnosis of logistics management. Subsequently, and from the implementation of the improvement based on programmed purchases through the MRP Purchasing Plan, simulations were carried out in the Arena software for type A materials in order to compare the current scenario with the implemented one after the improvement (reduction to 0 of the indicators), thus demonstrating the technical feasibility of the improvement. Next, the economic viability was verified by comparing the different indicators resulting from the improved and current state: NPV (S/ 576 275 Vs S/ 289 190), IRR (119% Vs 41%), Cost Benefit (4,35 Vs 1,88) and Recovery Period (21 days Vs 41 days), taking an initial investment (S/ 171 817 Vs S /330 000) and various income and expenses involved. Finally, the construction of social indicators such as added value (S/ 1 548 602,21), capital product ratio (9,01), labor productivity, capital intensity (0,11), and capital density (S / 4 909,05 for all months) were used thus demonstrating that the project is also socially viable.
