MY AGV SHOULD PICK MATERIALS FROM SOURCE 28 AND DROP IN OTHER 27 SINK(1-26) AND WHILE DROPPING ON EACH SINK IT SHOULD PICK MATERIAL FROM THEIR NEARBY SOURCE (1-26) AND DROPS IT IN ON 28. THE 27 SOURCES HAVE DIFFERENT ARRIVAL TIME THE AGV SHOULD DELIEVER FIRST TO THE SINK WHOSE SOURCE COMES FIRST EXAMPKE: IF SOURCE 2 GENERATES ITEM FIRST THE AGV SHOULD PICK FROM SOURCE 28 AND DOPS IN SINK 2 AND PICK MATERIAL FROM SOURCE 2 AND DROPS IN SINK 28 AND CONTINUE THE SAME LOGIC WHOSE GENERATE MATERIAL FIRST
