However, the majority of existing research in both domains uses optimization based models and methodologies such as integer programming, dynamic programming and local search. The increasing power of computing makes the Metaheuristics acceptable practically, to handle the complex scheduling and logistics problems efficiency. Complex optimization scheduling problems frequently arise in the manufacturing and transport industries, where the goal is to find a schedule that minimizes the total amount of time (or cost) required to complete all the tasks. We are especially interested in papers that use one or more of the following modeling and solution methods: robust optimization, approximate dynamic programming, simulation optimization, stochastic programming, integer programming, and meta-heuristics, and their integration with data analytic tools such as optimal learning, machine learning, neural networks, and data mining. 55 describes the generation of decision trees for selecting the appropriate scheduling rules in an FMS environment. This may be done in advance depending on the structure of the input data or even while scheduling (i.e first using a priority rule then make a partial schedule using it then changing the priority rule etc.) Analyzing the previous performance of the system (training examples) by means of this technique, knowledge is obtained that can be used to decide which is the most appropriate dispatching rule at each moment in time.
