This paper concerns with the concept of preemption in just-in-time single machine scheduling problem, with allowable machine idle time. We proposed a new model, with non-linear terms and integer variables which cannot be solved efficiently for large size problems due to its NP-hardness. To solve the model for real size applications, genetic algorithm is applied. These genetic procedures are also quite close to the optimum and provided an optimal solution for most of the test problems. Numerical examples show that the proposed algorithm is efficient and effective.
