Nonlinear adaptive resource management systems and methods are provided. According to one embodiment, a controller identifies and prevents resource starvation in resource-limited systems. To function correctly, system processes require resources that can be exhausted when under high load conditions. If the load conditions continue a complete system failure may occur. Controllers functioning in accordance with embodiments of the present invention avoid these failures by distribution shaping that completely avoids undesirable states. According to one embodiment, a Markov Birth / Death Chain model of the resource usage is built based on the structure of the system, with the number of states determined by the amount of resources, and the transition probabilities by the instantaneous rates of observed consumption and release. A control stage is used to guide a controller that denies some resource requests in real systems in a principled manner, thereby reducing the demand rate and the resulting distribution of resource states.

The present invention relates to an apparatus and method for stretch wrapping a load in an efficient manner so as to tightly and securely wrap the load at a desired tension without rupturing the packaging material. The method and apparatus compensate for variation in demand rate as the load is wrapped so as to apply the wrapping material to a load at a desired force, maintain the desired containment tension on the wrapping material on the load after wrapping, and prevent the wrapping material from rupturing during wrapping. The apparatus combines two systems, power assisted roller stretch (“PRS”) and roller stretch (“RS”) to vary the supply rate of the packaging material as the demand rate varies. The apparatus automatically switches between the two types of prestretch to achieve “high” and “low” wrapping force dependent upon the demand rate. Changes in the demand rate are sensed by monitoring changes in the payoff angle of the packaging material extending between the dispenser and the load.
