....the number of machines is arbitrary, the problem is NP Hard again. In [4] it is shown that a closely related problem, where p = m and where jobs have release dates, is of great interest for solving the openshop scheduling problem with unit execution time known as Omjp ij = 1j P w i U i . In [2], a dynamic programming algorithm with time complexity O(n 4m 2 2m 10 ) is proposed to solve both Pmjpmtn; p i = m; r i j P w i U i and Omjp ij = 1j P w i U i . In this paper we propose a necessary and su cient condition of existence of a solution for P jpmtn; d i j that can be ....
