Modelo de dinámica de sistemas para una cadena de suministro en el sector de repuestos de motocicletas, empresa base FANALCA S.A. (MABCREM)

Abstract

In this work the Dynamics of systems is used, due to its importance in the industrial engineering, in relation to the creation of simulation models and it is applied to the spare parts sector in FANALCA dedicated to the commercialization of motorcycles and their accessories, located in the City of Santiago de Cali, Valle del Cauca, Colombia. The model investigates the understanding of the structure and operation of the company FANALCA SA through the influences and feedbacks that are created between the main variables that make up the system, either in normal situations or in behaviors of some of its variables or modifications in the policies employed by the company named above. The variables were defined through research, research, interviews, analysis with executives and FANALCA workers. Subsequently the mathematical equations that detail their behavior were established. Through a series of tests, the model was evaluated, adjusting its parameters to achieve an ideal model that fits the reality of the company. This model is created according to what is proposed by experts and relevant historical data that are available. The dynamics of systems has rarely been applied to the motorcycle spare parts sector, however, its application to this sector is significant as a strength for making business decisions, since both qualitative and quantitative results of the company's behavior can be achieved without any need to intervene in real system, avoiding high costs and decreasing the number of data. An analysis of the company is presented under normal conditions, in various conditions of inventory management and in the particular scenario of a considerable increase in demand, suggesting changes to cope with these situations. Under normal conditions, the behavior of the company with respect to its main variables, which make up the model, is evident. This being the way to appreciate the policies that govern the actions, the behavior of the analyzed system is determined. The scenario presented in various conditions consists of a decrease in variables "spare parts availability" and "missing goods", to observe this scenario of external resources with which the company is able to satisfy the demand without generating sales and changes losses in the system according to the situation. In the scenario of a considerable increase in demand under normal conditions, the possible changes in policies that approve the problems generated in such a moment are best defined and analyzed. The results achieved correspond to the company having lower inventory levels while maintaining the same coverage and rotation values, making the inventory available to be as optimal as possible for sale and reducing the levels of obsolete inventories, this would translate into a better level of service to customers.
