Warranty claims have a significant impact on the financial aspect of the company, because of the funds that need to be reserved for repair of the defected products within the warranty period. The failure process is considered as a combination of market absorption and failure process. Prediction and determination of terminal call rate (TCR) is important for monitoring of the production system efficiency. Several models to predict TCR have been analyzed, such as Weibull model and the Markov Modulated Fluid model (MMFM). The models were validated against two types of data: a) from sales to failure, and b) from production to failure. The results show that MMFM model provides promising prediction results.

The transition model is represented in the form of discrete state space. The target values for each particular rank are deter mined by the user defined trajectory function. Optimal recruitment and transition dynamics is determined by the minimization of the differences between desired and actual state values. Analytical approach to the optimization is considered in order to provide proper control strategy.

The developed agent based anticipative model enables us to change the future as well as the past chain of events. Emergent synchronization patterns determined by the application of z-transform provide the base for determination of stability regions in systems of higher complexities. One of the important results provided is that the proposed agent-based system is apparently controllable by considering the frequency response of the system. The proof of the stability for the arbitrary set of proposed anticipatory agents is proposed.
