Claim One:
1. A tool for facilitating the analysis of a glass forming machine which includes a blank station for forming a parison from a gob of molten glass having a number of mechanisms, a blow station for forming a parison into a bottle, having a number of mechanisms, a feeder system including a shear mechanism for shearing a gob from a runner of molten glass so that it can be delivered to the blank station, a mechanism for transferring a parison from the blank station to the blow station and a takeout mechanism for removing a bottle from the blank station, wherein the glass forming machine has a set machine cycle time, wherein each of the mechanisms has a predetermined cycle which is completed during the time of one machine cycle, wherein the duration of each displacement of each of the mechanisms is determinable, wherein interferences exist between the motion paths of the gob, the parison, the bottle and individual mechanisms, wherein the thermal forming of the parison and bottle involve a number of thermal forming processes which are completed during the time of one machine cycle, each having a finite duration, wherein process air is supplied for at least one process for a finite duration by turning a supply valve “on” and then “off” during the time of one machine cycle, wherein an unwrapped bottle forming process wherein a gob of molten glass is sheared from a runner of molten glass, the gob is then formed into a parison in the blank station, the parison is then formed into a bottle in the blow station, and the bottle is then removed from the blow station, takes more than the time of one machine cycle to complete, and wherein the start of each displacement for each mechanism and the turning of a supply valve “on” and then “off” are controlled events which are started in a selected sequence, comprising a computerized model of a mathematical representation of a network constraint diagram of the unwrapped bottle forming process wherein a gob of molten glass is formed from a runner of molten glass, the gob is then formed into a parison in the blank station, the parison is then formed into a bottle in the blow station, and the bottle is then removed from the blow station.
