    Analysis of chaotic behaviour in supply chain variables
    (Journal of Economics, Finance and Administrative Science, 2011-12) Peña Zapata, Gloria Elena; Ramírez Echeverri, Sergio Augusto; Universidad EAFIT. Departamento de Ingeniería de Producción; ramire@eafit.edu.co; gepena@unal.edu.co; Gestión de Producción y Logística
    In this article we develop a supply chain model of four levels through the utilization of system dynamics with Ithink® and Mathlab® softwares to analyze data -- The supply chain is studied from the chaos theory perspective, which helps identifying the sensitive variables that can lead to a state of chaos -- A generic structure model that comprehends factory links, distribution, wholesale, retail and the client is constructed -- The difficulty of operations and logistics managers to decide how much to order and when to do it is simulated accordingly to what occurs in the links of the preceding and subsequent levels with two decision parameters: The first parameter denominated A indicates the participation (between 0 and 1) of the number of product units that are taken into account in the actual stock and the pending orders at the moment of performing an order – Thesecond parameter, denominated B, is the participation (between 0 and 1) of the number of units in the supply line (in transit) at the moment of performing orders of each of the links of the supply chain

    The impact of supply chain decisions, using dynamic systems, of an aquatic garment manufacturing company
    (Revista Ingeniería Industrial, 2010-06) Peña Zapata, Gloria Elena; Pineda Toro, Mauricio; Escalante Ochoa, Daniel; Ramírez Echeverri, Sergio A.; Peña Zapata, Gloria Elena; Pineda Toro, Mauricio; Escalante Ochoa, Daniel; Ramírez Echeverri, Sergio A.; Universidad EAFIT.

    This article shows the supply chain model of the company Creaciones Nadar S.A. Thatmanufactures aquatic sports garments -- The chain links are the clients, the store, the warehousing, the internal and satellite plants and raw material supply -- The supply chain of Creaciones Nadar S.A. is a complex system given the different agents that form the feedback structures and delayed effects on behaviors -- The supply chain has different dynamic behaviors generated by changes in external factors such as garment’s demand, number of required workers in the company’s plant, the warehousing, and the store, among other -- A dynamic system methodology and the software Ithink® were used to model the chain; moreover, different scenarios were analyzed using simulation and taking into account the most representative variables to be modified -- The obtained results allow Creaciones Nadar S.A. to determine policies and parameters and to obtain the best kind of benefits for the company
