PROCESS FLOW OPTIMIZATION IN MANUFACTURING
Optimizing a multiple machine production line, in which operation of at least some of the machines depends on others. A productivity system examines performance indicators of a set of machines, which are disposed to cooperate in a production line, and sets control variables for each of those machines, with the effect of optimizing the production line. The productivity system receives a set of KPIs for each machine, and provides a set of control variables for each machine. The productivity system determines the control variables for each machine so as to optimize the production line.
1 . A method of optimizing a multiple machine line, comprising:
collecting one or more key performance indicators for one or more elements on a production line;
storing said one or more key performance indicators in a buffer;
using a computer to analyze said key performance indicators;
outputting control variables to one or more of the elements on said production line, to increase the efficiency of said production line.
2 . The method of claim 1 , wherein:
said key performance indicators include one or more of whether one or more of each elements is active, whether any element is starved, whether each element is full, a current run rate or cycle time, information about element status or operability, wait time for operation, and information relating to a given unit being processed
3 . The method of claim 2 , wherein:
the efficiency of said production line is increased by increasing finished goods produced per unit time.
4 . The method of claim 2 , wherein:
the efficiency of said production line is increased by decreasing the amount of down time for one or more elements in the production line
5 . The method of claim 2 , wherein:
the efficiency of said production line is increased by decreasing the mean time between failures on the production line.
6 . The method of claim 2 , wherein:
the efficiency of said production line is increased by increasing the overall average speed of said production line.
7 . The method of claim 1 , wherein:
one or more of said key performance indicators indicate whether any element is in one or more of the following states: faulted, starved, saturated, operable, and active.
8 . The method of claim 1 , wherein:
one or more of said key performance indicators indicate whether any element is partially or wholly inoperable.
9 . The method of claim 1 , wherein:
said computer includes a storage medium.
10 . The method of claim 1 , wherein:
said computer includes non-transitory machine-readable medium.
11 . The method of claim 10 , wherein:
said non-transitory machine-readable medium comprises one or more of magnetic storage media, optical storage media, magneto-optical storage media, read only memory, random access memory, erasable programmable memory, and flash memory.
