Correlations between emergent synthesis classes: Due date based control and planning of job shops

Emergent synthesis classifies problems of artifactual system behavior into three classes depending on the completeness in the description of the system environment and specifications. This paper introduces correlations between the problem classes and their problem solvers. To illustrate the discussed correlations, a job shop model with make-to-order manufacturing environment is presented. The problem frame of the control and planning in the model is shown to be a Class III type problem and approached by using the correlated problem solvers of the three classes. The purpose of the job shop is to evaluate the overlapped space between the specifications of the customers and the capabilities of the manufacturing system and to form the behavior of the system in order to fulfill orders with high accuracy. The structure of the model and the developed solvers indicate that to solve a Class III type problem, various Class I and Class II problem solvers are relevant.
