Abstract: A method is provided for processing data to replicate lifecycle threads in the development of a structural product. The method includes defining a source lifecycle thread from process-related information for development of the structural product, and defining and matching a target lifecycle thread to the source lifecycle thread. The process, and source and target lifecycle thread are expressible as respectively a network and sub-networks of tasks described by a plurality of attributes. Defining and matching the target lifecycle thread includes selecting a plurality of candidate target tasks from the plurality of tasks; matching a candidate target task to a particular source task using a distance map for an attribute of the plurality of attributes, with the distance map including only unique values of the attribute and distances between the unique values; and back-chaining through the source lifecycle thread to match candidate target tasks with respective source tasks.

Abstract: A method is provided that includes receiving process-related information describing a hierarchical process for production of a product. The process may include segments each of at least some of which include segment components. The method also includes determining an instance in which the segment components are total-ordered, which may include determining an instance in which the segments are total-ordered. For the total-ordered segments, the segment components may be partitioned by disjoint collections based upon earliest availability to produce earliest-available partitions, and separately based upon latest availability to produce latest-available partitions. Order flexibility may be identified for each segment component based upon membership in both earliest-available and latest-available partitions, and an instance in which each partition in both the earliest-available and latest-available partitions contains only one order-inflexible segment component may be determined.

Abstract: A method is provided that includes receiving process-related information describing a process for production of a product, including a logical sequence of tasks to produce respective internal products of the process. The method also includes constructing a schedule for the process based on the process-related information, with the process schedule being for execution of at least some of the tasks each of which utilizes or requires inputs including temporally a last input. Construction of the process schedule includes separating each of at least some of the respective tasks into a closure portion that requires availability of the last input of its task before being initiated, and a distinct precursor portion capable of being initiated before the respective last input is available. The closure portions of the respective tasks may be temporally sequenced without intervening precursor portions, and the precursor portions may be prepended to respective, temporally-sequenced closure portions.

Abstract: Methods and systems for constructing a scalable feed-forward process are provided. The method includes identifying a plurality of segments of the process wherein the segments define a feed-forward network which is used to constrain the creation of more detailed segment components. The method also includes modeling each component by defining component outputs and determining component inputs that are combinable using the model to produce the defined output, ordering the components hierarchically based on the respective component outputs and inputs, determining segment inputs and outputs based on the component outputs and inputs, and ordering the segments hierarchically based on the respective segment outputs and inputs.

Abstract: Methods and systems for displaying a network structure using force-directed layout are provided. The network includes a plurality of nodes, each node including an associated slack parameter having a value. The method including selecting a central time-directed axis, positioning each network node along the axis using the associated slack parameter value of the network node to determine a distance from the central time-directed axis, and applying force-directed computations to sets of concurrent nodes.

Abstract: An elevated and elongated boom is centrally pivoted for rocking movement in a vertical plane through the horizontal plane. Provision is made to align such plane with the direction of the wind. A pair of free wings are mounted on the fore and aft ends of the boom with control panels being oscillatably mounted on such wings for determining, by their relative positions and aerodynamic equilibrium reaction thereto, the angle of attack of such wings. Provision is made to control the relative positions of the control panels with respect to their respective wings so that the wings have angles of attack of opposite sense, with such senses being reversed as the boom approaches each predetermined limit of its rocking motion. The fore (canard) and aft wings are positioned and sized relative to each other to equalize their moment contributions to the rocking motion of the boom. Alternative wing structures are disclosed.
