Abstract:
1. A method of analyzing a manufacturing system, the system including plurality of manufacturing resources, a set of orders being currently appointed for processing by the manufacturing system, each order of the set of orders requiring performance of at least one task, each task to be performed by at least a respective one of the manufacturing resources, the method comprising: determining stochastic parameters for each task of said plurality of tasks; calculating a loading profile function for at least one of said manufacturing resources that is allocated to at least one of said plurality of tasks, said loading profile function being a function of time and representing a probability that said each manufacturing resource is occupied at a given time, said calculating based at least in part on said stochastic parameters of said tasks; and displaying a graphic display page in which said loading profile function is displayed as a graph curve; wherein; said calculating a loading profile function includes calculating a most likely loading profile function, a minimum loading profile function and a maximum loading profile function for said each manufacturing resource; and said displaying includes including in said graphic display page a respective graph curve for each of said most likely loading profile function, said minimum loading profile function and said maximum loading profile function; the method further comprising: the method further comprising: calculating an overload probability function for said each manufacturing resource; and wherein said displaying includes including in said graphic display page a graph curve that represents said overload probability function.
