1. A method for continuously optimizing data archive management scheduling, said method comprising: a job scheduler receiving inputs from an archive management system, wherein the inputs comprise task information, replica placement data, infrastructure topology data, and resource performance data; modeling a flow network from the received inputs, such that the flow network represents data content, software programs, physical devices, and communication capacity of the archive management system, and such that an optimal path of the flow network from a task of at least one archive management task to a worker program of the archive management system represents an optimal initial schedule for the worker program to perform the task; a processor of a computer system computing the optimal initial schedule from the optimal path in the flow network; transferring the computed optimal initial schedule to the archive management system to perform the optimal initial schedule; receiving monitoring results of operations of the transferred optimal initial schedule from the archive management system; creating an adjusted schedule as a result of dynamically adjusting the optimal initial schedule based on the received monitoring results; and transferring the adjusted schedule to the archive management system to perform the adjusted schedule such that the archive management system generates new monitoring results of operations of the transferred adjusted schedule;

creating edges organized in seven types comprising EDGE_ 01 , EDGE_ 12 , EDGE_ 23 , EDGE_ 34 , EDGE_ 45 , EDGE_ 56 , and EDGE_ 67 , wherein a first type EDGE_ 01 comprises a first edge directed from the source vertex of LEVEL_ 0 to a first task vertex of LEVEL_ 1 , the first edge indicating that a first task associated with the first task vertex is scheduled by the job scheduler, wherein a second type EDGE_ 12 comprises a second edge directed from the first task vertex of LEVEL_ 1 to a first volume vertex of LEVEL_ 2 , the second edge indicating that a first storage device volume associated with the first volume vertex stores latest data necessary to perform the first task, wherein a third type EDGE_ 23 comprises a third edge directed from the first volume vertex of LEVEL_ 2 to the first volume vertex of LEVEL_ 3 , wherein a fourth type EDGE_ 34 comprises a fourth edge directed from the first volume vertex of LEVEL_ 3 to a first server vertex of LEVEL_ 4 , the fourth edge indicating that a first computing server associated with the first server vertex is physically coupled to the first storage device volume, wherein a fifth type EDGE_ 45 comprises a fifth edge directed from the first server vertex of LEVEL_ 4 to the first server vertex of LEVEL_ 5 , wherein a sixth type EDGE_ 56 comprises a sixth edge directed from the first server vertex of LEVEL_ 5 to a first worker vertex of LEVEL_ 6 , the sixth edge indicating that the first computing server associated with the first server vertex hosts a first worker program associated with the first worker vertex, and wherein a seventh type EDGE_ 67 comprises a seventh edge directed from the first worker vertex of LEVEL_ 6 to the sink vertex of LEVEL_ 7 , the seventh edge indicating that the first worker program completes operations scheduled by the job scheduler; assigning weights to the created edges, wherein the first edge of the first type EDGE_ 01 has a first weight equal to a time unit to perform the first task, wherein the second edge of the second type EDGE_ 12 has a second weight equal to a volume usage of the first task, wherein the third edge of the third type EDGE_ 23 has a third weight equal to a volume throughput of the first storage device volume indicating a number of tasks that the first storage device volume can simultaneously support, wherein the fourth edge of the fourth type EDGE_ 34 has a fourth weight equal to a capacity of a communication channel between the first storage device volume and the first computing server, wherein the fifth edge of the fifth type EDGE_ 45 has a fifth weight equal to a processing throughput of the first computing server, and creating at least one path from the source vertex to the sink vertex following created edges such that the created at least one path represents a respective job schedule for a task in the path by use of at least one storage device volume and at least one computing server in the path to be performed by at least one worker program in the path, wherein the optimal path is a path having a minimum sum of weights of edges in the path.
