Claim One:
1. A method for simulating a production system configured to produce a product comprised of a plurality of different components sourced from different vendors, the method comprising: creating an entity for each of the plurality of different components; assigning to each entity learning curve parameters for individual asynchronous stochastic learning curves associated with each of the plurality of different components of the product, wherein assigning the leaning curve parameters comprise: assigning a time needed to process the Xi th unit of the i th component in the system taking into consideration flattening of the learning curve and is given by the following formula: Y i,xi =Max[10 [log(ai+bi log(xi)], 10[log(ai)+bi log(mi)] a time parameter, a j , which represents a time needed to produce a first unit of an i th component; a time learning progress rate, b j , which represents a learning progress rate of the i th component; and a learning curve rate, c j , for the i th component; associating a delay with each of the plurality of different components; receiving master schedule data for manufacturing a plurality of the product, wherein the master schedule data includes one or more schedule dates for each of the different components necessary to produce the product; assigning a serial number to each of the plurality of different components; simulating production of the plurality of different components sourced from different vendors via a plurality of cycles corresponding to the plurality of the product; storing a production start time and a component arrival time associated with each serial number in a memory; and outputting results of the simulated productions for analysis.
