A method and system schedules inbound inquiries, such as inbound telephone calls, for response by agents in an order that is based in part on the forecasted outcome of the inbound inquiries. A scheduling module applies inquiry information to a model to forecast the outcome of an inbound inquiry. The forecasted outcome is used to set a priority value for ordering the inquiry. The priority value may be determined by solving a constrained optimization problem that seeks to maximize an objective function, such as maximizing an agent's productivity to produce sales or to minimize inbound call attrition. The inbound call may be placed on a virtual hold or be responded to on a real-time basis based on the inbound inquiry's priority value. A modeling module generates models that forecast inquiry outcomes based on a history and inquiry information. Statistical analysis such as regression analysis determines the model with the outcome related to the nature of the inquiry. Forecasted outcomes are based on the goal of the inbound calls and include factors such as probability an inbound caller will hang up, probability that an inbound caller will alter a business relationship based on hold time, probability that an inbound caller will make a purchase, and the relative probable reward of responding to an inbound call.

The present method specifies the document, its content components, its layout requirements, and its desired aesthetic criteria are expressed as elements of a constraint optimization problem which when solved, results in an automated document layout for the set of content components that satisfies not only certain primitive content and layout constraints, but which also advantageously fulfills desired design properties and which provides a way to ensure that the generated document is well designed. The method for automatic document layout comprises the steps of determining a set of variables that can be adjusted to achieve a satisfactory layout; expressing said satisfactory layout as a set of constraints on said determined set of variables wherein at least one of said set of constraints is expressed as being optimizable; and solving said constraints to find a layout which solves for the variables over the constraints.

The invention relates to an optimization method for constrained problems based on an evolutionary optimization algorithm. For constrained optimization problems, this method adopts the method of penalty function to deal with constrained problems, and uses swarm intelligence optimization algorithm to optimize the function with penalty items. Using this optimization method, the penalty coefficient of each constraint item in the algorithm iteration process is jointly determined by the number of all individuals in the population that meet the constraint conditions, the degree of violation of constraints, and the sum of the objective functions of all individuals in the population. This avoids the problem that the penalty coefficient is too large or too small, prompts the algorithm to achieve a balance between the satisfaction of the constraints and the non-satisfaction of the individuals in the population as much as possible in each iteration, and avoids that the optimization of practical engineering problems cannot give a suitable penalty coefficient The problem.
