Dynamic resource allocation using known future benefits
First Claim
1. A computer implemented method of resource allocation to yield benefit comprising the steps of:
- generating an input matrix of customer demands for resources indexed by customers and time period where a benefit function is known in advance; and
producing from the input matrix an output matrix of allocations of resources to customers to realize a benefit, wherein said output matrix is indexed by customers and time periods;
during a time interval, reallocating a resource from a first customer to a second customer and making the resource unavailable to any customer during the time interval that the resource is being allocated to the second customer, wherein the step of making the resource unavailable comprises including a step of making the resource which is a server unavailable to any customer during the time interval that the resource is being allocated to the second customer, wherein the time interval is set to equal a non-negligible amount of time required for the server to prepare to serve a new customer.

Abstract
A benefit task system implements a policy for allocating resources to yield some benefit. The method implemented may be applied to a variety of problems, and the benefit may be either tangible (e.g., profit) or intangible (e.g., customer satisfaction). In one example, the method is applied to server allocation in a Web site server “farm” given full information regarding future loads to maximize profits for the Web hosting service provider. In another example, the method is applied to the allocation of telephone help in a way to improve customer satisfaction. In yet another example, the method is applied to distributed computing problem where the resources to be allocated are general purpose computers connected in a network and used to solve computationally intensive problems. Solution of the Web server “farm” problem is based on information regarding future loads to achieve close to the greatest possible revenue based on the assumption that revenue is proportional to the utilization of servers and differentiated by customer class. The method of server allocation uses an approach which reduces the Web server farm problem to a minimum-cost network flow problem, which can be solved in polynomial time. Similar solutions are applicable to other resource allocation problems.
