  • System and method of determining software maturity using Bayesian design of experiments
    Patent number: 7640537
    Abstract: A system and method for determining software maturity is disclosed. The method may include building an uncensored belief distribution from a set of observed test data, building a belief distribution based on one or more improvement factors, convoluting the uncensored belief distribution with the belief distribution on improvement factors to form a joined-censored-belief distribution, and translating the joint belief distribution into an a priori belief distribution to assess a level of software maturity.
    Type: Grant
    Filed: October 4, 2006
    Date of Patent: December 29, 2009
    Assignee: Lockheed Martin Corporation
    Inventor: David Judson Simkins
  • System and method of determining software maturity using Bayesian design of experiments
    Patent number: 7216339
    Abstract: A system and method for determining software maturity, the method comprising the steps of building an uncensored belief distribution from a set of observed test data, building belief distributions based on improvement factors, convoluting the uncensored belief distribution with the belief distribution on improvement factors to form a censored belief distribution. From these belief distributions, a 3-way assessment is made including establishing an a priori belief distribution to assess a level of software maturity.

  • System and method for modeling a propagation and containment process
    Publication number: 20040138863
    Abstract: The systems and methods for modeling of a propagation and a containment process described herein enable the modeling of containment processes by mathematically mapping a containment process onto a topological model. The systems and methods described herein can model the effects of various degrees of data fusion and automation that are present in specific locations throughout the containment process. In addition, human and automated responses to propagated defects within the containment process can also be modeled.

  • System and method for modeling multi-tier distributed workload processes in complex systems
    Publication number: 20040138867
    Abstract: A method for modeling a distributed workload problem resolution process including building a topological model of a workload process comprising a plurality of hierarchical levels, each level comprising at least one node, and assigning at least one behavior to each node, the behavior configured to model a component of the problem resolution process, wherein at least one of the behaviors are configured to model a degree of merit. A degree of merit may include a level of data fusion, a level of automation, or a combination thereof.
