A process management system uses a radio frequency identification (RFID) detection system in the form of, for example, a phased array antenna based RFID detection system to track and manage material storage and flow in a manufacturing process or plant. The process management system operates in conjunction with the various machines that implement manufacturing stages or steps of the manufacturing process to assure that the correct materials and processing procedures are used at or on the various production machines of the process to produce a particular product as defined by a job number or job order. The process management system is thereby able to increase the efficiencies of the plant and to increase the quality of the plant production by reducing or eliminating waste, manufacturing errors and shipping errors in the production facility.

1. A method of controlling a manufacturing process associated with a manufacturing job order, comprising: identifying, by a command system, a job order recipe associated with the manufacturing job order,wherein the job order recipe identifies one or more material inputs to a manufacturing stage that implements a production machine to produce a manufactured product in accordance with the manufacturing job order,searching, by the command system, a database to identify one or more radio frequency identification (RFID) tags that are physically associated with each of the one or more material inputs;determining, by the command system, a position of the one or more RFID tags; andcontrolling, by a process controller in communication with the command system, operation of the production machine implemented by the manufacturing stage based upon whether the position of the one or more RFID tags matches a location of the manufacturing stage as indicated by the manufacturing job order. 2. The method of claim 1, wherein the act of searching the database to identify the one or more RFID tags comprises: searching the database to identify one or more RFID tags having one or more respective unique RFID tag numbers that correlate to the one or more material inputs as specified by the job order recipe. 3. The method of claim 1, wherein the act of controlling the operation of the production machine comprises: generating a notification indicative of the one or more material inputs being at an improper location when the position of the one or more RFID tags does not match the location of the manufacturing stage as indicated by the manufacturing job order. 4. The method of claim 1, wherein the act of controlling the operation of the production machine comprises: disabling operation of the production machine such that the one or more material inputs are not subjected to the manufacturing stage when the position of the one or more RFID tags does not match the location of the manufacturing stage as indicated by the manufacturing job order. 5. The method of claim 1, wherein the one or more material inputs include (i) raw material used by the production machine to produce the manufactured product, or (ii) components of the production machine. 6. The method of claim 1, further comprising: controlling, by the command system, an antenna to scan a region in which the manufacturing process occurs, the antenna having an associated coverage area; andresolving, by the command system, a location of the one or more RFID tags within the region that is less than the coverage area of the antenna based on a signal transmitted by the one or more RFID tags. 7. The method of claim 1, further comprising: monitoring changes in the position of the one or more RFID tags attached to each of the one or more material inputs over time. 8. A method of monitoring a manufacturing process associated with a manufacturing job order having a job order recipe, comprising: identifying, by a command system based upon the job order recipe, (i) a first and a second manufacturing stage, (ii) a first material input used at the first manufacturing stage to produce an intermediate output, and (iii) a second material input that is the intermediate output, which is used at the second manufacturing stage to produce a manufactured product;identifying, by the command system as indicated by the job order recipe, a first radio frequency identification (RFID) tag that is physically associated with the first material input and a second RFID tag that is physically associated with the second material input;determining, by the command system, a position of the first material input and a position of the second material input based upon a position of the first RFID tag and a position of the second RFID tag, respectively; andindicating, by the command system, (i) whether the first material input is correctly located at the first manufacturing stage as specified by the manufacturing job order based upon the determined position of the first RFID tag, and (ii) whether the second material input is correctly located at the second manufacturing stage as specified by the manufacturing job order based upon the determined position of the second RFID tag. 9. The method of claim 8, wherein the first RFID tag includes data identifying the first material input, and wherein the second RFID tag includes data identifying the intermediate output. 10. The method of claim 8, further comprising: generating, by the command system, a notification indicative of the first or the second material input being at an improper location when the first or the second material input is not located at the first or the second manufacturing stage, respectively, as indicated by the manufacturing job order. 11. The method of claim 8, further comprising: disabling operation of a first production machine associated with the first manufacturing stage such that the first material input is not subjected to the first manufacturing stage when the first material input is not correctly located at the first manufacturing stage; anddisabling operation of a second production machine associated with the second manufacturing stage such that the second material input is not subjected to the second manufacturing stage when the second material input is not correctly located at the second manufacturing stage. 12. The method of claim 8, further comprising: searching a database to identify the first and second RFID tags having one or more respective unique RFID tag numbers that correlate to the first material input and the second material input, respectively, as specified by the job order recipe. 13. The method of claim 8, further comprising: controlling, by the command system, an antenna to scan a region in which the manufacturing process occurs, the antenna having an associated coverage area; andresolving, by the command system, a location of the first and second RFID tags within the region that is less than the coverage area of the antenna based on a signal transmitted by the first and second RFID tags. 14. The method of claim 8, further comprising: monitoring changes in the position of the first and second RFID tags over time to track movement of the first material input and the second material input. 15. A command system for controlling a manufacturing process associated with a manufacturing job order, comprising: a database configured to store a job order recipe associated with the manufacturing job order, the job order recipe identifying one or more material inputs to a manufacturing stage that is used to produce a manufactured product as specified by the manufacturing job order;a processor configured to identify, from the job order recipe stored in the database, one or more radio frequency identification (RFID) tags that are physically associated with the one or more material inputs; andan RFID detection controller configured to periodically monitor a manufacturing location that is co-located with the manufacturing stage, to detect the one or more RFID tags at the manufacturing location, and to determine a position of the detected one or more RFID tags within the manufacturing location, andwherein the processor is further configured to check, when the manufacturing job order is executed, whether the position of the detected one or more RFID tags matches a location associated with an input to the manufacturing stage as indicated by the manufacturing job order. 16. The command system of claim 15, wherein the RFID detection controller is further configured to control an antenna network, and to periodically monitor the manufacturing location by operating an antenna within the antenna network to steer a beam through the manufacturing location. 17.
