1. A method of modeling the manufacturing of a product in a pull and push manufacturing system, where the product comprises
at least one model and each model includes at least one component, said method comprising:
simulating operation of the manufacturing system, wherein simulating comprises:
generating a master firing order schedule (MFOS) for a plurality of orders for at least one model of the product over a defined
time period, wherein the orders are in a predefined sequence and each order includes a defined release time;
generating a component firing order schedule (CFOS) for a plurality of components corresponding to the models ordered in the
MFOS, wherein the components are in a predetermined sequence and each component has a defined release time, the predetermined
sequence being set based upon the defined release times of the respective orders and manufacturing times associated with the
components such that at least one component for an order is capable of being released after at least one component for a subsequent
order;
releasing each order in the MFOS at a respective release time and releasing each component in the CFOS at a respective release
time;
producing the components at a set number of production centers for the respective set manufacturing times, wherein when a
subsequent component is released before all preceding components in the CFOS are produced the subsequent component is buffered
until the preceding components are produced; and
assembling the orders from the produced components at a set number of assembly lines for set assembly times associated with
the models ordered, wherein when a subsequent order is released before the models in all preceding orders in the MFOS are
assembled the subsequent order is buffered until the models in all preceding orders are assembled; and
adjusting at least one of the set assembly time for at least one of the models of the product, the set manufacturing time
for at least one of the components of the models, the set number of production centers or the set number of assembly lines
based upon at least one of a subsequent component or a subsequent order being buffered.
