1. A method of analyzing a manufacturing system, the system including a 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; and 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.
