Improvement for production management and control using lean manufacturing tools in the manufacturing of posts and accessories

Abstract

The problem identified is the poor management and control of production, which includes direct consequences with regard to quality, planning of operations and work method; generating mainly penalties for non-fulfillment of orders, increased operating costs and lost opportunity cost that negatively affect the efficiency of the production process of concrete posts and accessories in a SME company. The implementation of an improvement model is proposed applying the Lean Manufacturing philosophy; whose application is focused on improving 3 main waste in the production system: defects, inventory and waiting time. The proposals of the study generated a reduction in the percentage of defects in the company by 6.46%, 9.50% in the case of penalties for non-compliance with orders, 34.67% in the cycle time and a 21% increase in the OEE of the machines.
