Abstract: Given a set of input data and one or more performance metrics, this method searches directly for a region of specified size, said size representing a selected amount of random variation of the data that provides a preferred, but not necessarily optimal, value of the performance metric across the region. Repeated executions of this method over time yield a good, but not necessarily provably optimal, path through unstable conditions, as for a vessel or aircraft seeking a relatively quick path through changing turbulence. Using repeated executions to derive paths also supports selection of smooth automatic control, over time, of a system subject to random variations in conditions, this method greatly reduces sharp changes in control parameters as conditions change, while selecting good sets of control parameters at each re-computation.

Abstract: Numbers of servers at latter stage services are synchronized with arrivals of customers at the latter stage services. Detecting entering customers' entries and passages by intermediate points are communicated to a computer. The computer predicts arrivals of customers for the latter stage services and needs for increases or decreases in numbers of servers. Lead times allow changing numbers of servers at the latter stage services to meet changing needs. Detections of times of servers with customers and detections of arrivals of customers at the latter stage services are communicated to the computer aid the estimations of changed requirements for numbers of servers. The computer provides the estimations of server requirement changes to managers and automated controllers with sufficient lead time to facilitate smooth transitions in increasing or decreasing the numbers of servers. Wait lines at checkout registers, call center on-hold times and inter-computer communication delays are avoided.

Abstract: Simulation is used to determine optimal dialer parameters for a predictive dialing system. A call history is logged over a period of time for a plurality of outgoing calls initiated by the predictive dialing system. The call history includes call data for each of the outgoing calls. A simulation is run on the call history by adjusting one or more dialer parameters and determining one or more values for those dialer parameter values that provide at least a target agent utilization within the simulation without causing a threshold abandonment rate to be exceeded within the simulation. Timing and/or quantity of outgoing calls to be initiated by the predictive dialing system are determined based, at least in part, on the one or more values for the dialer parameters determined from the simulation. The predictive dialing system initiates outgoing calls in accordance with the determined timing and quantity.

Abstract: A separator provides improvements for better separation of an effluent into constituent parts and greater ease of use. A tapered basket provides improved flow and better filtration. A baffle directs effluent into the basket with greater force. An asymmetrical flange prevents mis-orientation the basket and baffle. An improved oil valve provides a locking mechanism to prevent dislodging of the valve during cleaning. An alternative valve uses a sensor to sense an oil/water interface and close the oil valve appropriately. A top seal prevents leakage of effluent at connection points with the lid of the housing. An underground unit allows below floor level installation of the separator. A bidirectional unit can be reversed to provide flow in either direction. A dual purpose tank can be used to store both separated oil and oil from operations for common removal.

Abstract: A method for controlling arrivals to servers, comprising: regulating arrivals, by initiating a processor generating arrivals or by re-routing or turning away arrivals; measuring durations of service; computing and updating time statistics, including mean, minimum, maximum expected and standard deviation of duration of service thereby estimating expected duration of service; measuring transit times from the point of regulating arrivals to start of service and thereby estimating expected transit times; measuring a ratio of numbers of service initiations to numbers of arrivals at the point of regulating arrivals; recording starting time of each current service; noting present time; comparing present time to starting time, and thereby determining time in progress for each service; comparing time in progress to expected duration of service, and estimating time remaining in service for each customer currently in service; comparing estimated time remaining in service to estimated transit time from the point of regul
