The authors develop a mixed integer programming formulation for a single machine scheduling problem with job release times. The objective function analysed is the weighted sum of job starting times. As a relaxation the associated model with identical release times is used and the authors provide valid inequalities for the general problem.
The authors present a solution approach based on this formulation using a combination of cutting planes and branch-and-bound. The computational results of a first implementation for problems with up to 30 jobs indicate that the efficiency of the approach dramatically decreases when the problem size increases. But the authors mention some improvements to overcome this disadvantage of the present algorithm.
