DING Wei. Heuristic Algorithm of the Q//CmaxProblem on MultiTasks with Uniform Processors[J]. Acta Scientiarum Naturalium Universitatis SunYatseni, 2010,49(1):5-8.DOI:
To study the Cmax problem on manygroup jobs with one generalpurpose machinery and n specialpurpose machineries that they are with the different speeds. This problem is always NPC problem
so the approximate method is usually to be found. An improved LPT algorithm and the upper bound performance are given. The ratio of the approximate solution and the best way is T/T*≤1+1/∑〖DD(X〗i∈I〖DD)〗si
it means that the complete time using this approximate method is 1/∑〖DD(X〗i∈I〖DD)〗si more than the best in worst condition.
