1. A system executing on a computer for designing and constructing of multi-loop autonomic managers, including a design apparatus and a construction apparatus, wherein, said design apparatus adds at least one loop between an analysis part and a planning part, and forms a multi-loop autonomic manager as an extension to an autonomic manager of a classical autonomic element model; and said multi-loop autonomic manager uses a diagnostic flowchart to express fault-diagnosing work steps, said fault-diagnosing work steps form a process of repetitive “hypothesis-generating→investigating→discovering→concluding”, and achieving a final fault-diagnosing conclusion, wherein said multi-loop autonomic managers, under an autonomic computing reference architecture, forms a hybrid autonomic computing reference architecture combining classical and non-classical autonomic elements.
