System-of-Systems Enterprise Logistics Modeling Optimization Technologies Human Performance Prognostics and Health Management Sensitivity and Uncertainty

The Center for Systems Reliability (CSR) was established at Sandia National Laboratories to partner with and support U.S. government agencies and commercial organizations on technical programs that involve system and system-of-systems (SoS) reliability, readiness, sustainment and related technologies. The CSR combines Sandia's world-class technologies, experience, software, and facilities to provide...

Capability Portfolio Analysis Tool CPAT is a powerful fleet management analysis tool which optimizes investment and fielding decisions to provide maximum fleet performance under cost, schedule and programmatic constraints. It is capable of solving highly complex fleet modernization optimization problems – problems spanning many mission areas and modernization programs over...

Analysis of Decision-Making Responses DYMATICA™ (Dynamic Multi-scale Assessment Tool for Integrated Cognitive-behavioral Actions) is a computational approach to help decision makers better understand and anticipate the decision calculus and likely responses of populations, groups, and governmental institutions to different situations and conditions. The intent of DYMATICA is to minimize the...

Typical DYMATICA Assessments  DYMATICA models have assessed different geopolitical and socio-cultural narratives pertaining to the internal perceptions of a country’s status, capabilities, and hegemony over other countries. This involves the modeling of PMESII-PT factors associated with a country’s economic and military capabilities, as well as their self-perceptions, behavioral tendencies, and internal...

The DYMATICA computational modeling structure simulates interactions among populations, groups, and governmental organizations within selected country(ies) of interest (COI). The DYMATICA structure and process is based on a specific combination of well-established psychological, social, and economic theories of decision making, as well as established techniques in knowledge elicitation, statistics, system...

Integrated Supply and Repair Chains Enterprise logistics modeling enables the exploration of long-term performance for a global sustainment infrastructure. Analysts are motivated to model the enterprise to better understand anticipated lifecycle costs, evaluate sustainment requirements, and perform a variety of sustainment-related trade studies. This capability can be used for a...

Human Performance and Effectiveness in a System-of-Systems Assessing the involvement of humans in a system-of-systems (SoS) is difficult because of the number of humans and the poorly defined nature and variety of tasks that each human must perform. Sandia has developed an approach to the problem that is analogous to...

Microgrid Design Toolkit Microgrids are organized collections of distributed energy resources (DER) and controls that can operate autonomously (independent of a bulk power grid) when necessary (or always) to provide electrical power. They support resiliency, security, efficiency, local control, and increased access to renewable resources. They can provide reliable power...

Maximizing Performance and Cost Effectiveness Optimization is the process of varying input parameters to a model with the ultimate goal of achieving improved performance for one or more objectives. In most problems of interest, there are multiple objectives that must be simultaneously optimized and multiple constraints that must be respected....

Reliability Analysis and Optimization Suite The Pro-Opta software package is a reliability analysis and optimization suite that provides an analyst with the information needed to make strategic decisions in the competitive marketplace. The tool offers the flexibility to create a system’s reliability model using either field data (maintenance records) or...

Failure Prediction to Optimally Balance Maintenance and Operations Maintenance of critical systems is clearly important, but it also entails significant costs in terms of parts, labor, and loss of operational availability. Maintenance based on regular intervals is likely to be performed more often than needed leading to correspondingly higher costs....

Support Enterprise Model - A logistics modeling, analysis, and decision support tool The Support Enterprise Model is a discrete event simulation tool designed to model and simulate operation and support activities of a worldwide sustainment system. The general objective of SEM is to help characterize the sustainment system performance including...

Understanding the input and output variability of a system model Sensitivity and uncertainty analysis is often thought of as one activity, relating to the study of variability in a system model. It actually represents two distinct concepts, each with their own purpose, that are frequently explored simultaneously. Uncertainty analysis attempts...

System of Systems Analysis Toolset SoSAT is a tool designed to model and simulate multi-echelon operations and support activities of a system-of-systems (SoS). It provides logistics analysts with the ability to define operational and support environments of a SoS, ascertain measures of platform and SoS-level performance effectiveness, and determine logistics...

Multi-echelon enterprise lifecycle cost analysis tool The System-of-Systems Analysis Toolset Enterprise (SoSAT Enterprise) provides the ability to model global logistics. The tool enables analysts to perform SoS analysis for understanding characteristics of large-scale interdisciplinary problems that involve multiple distributed systems that are embedded in networks at multiple levels and domains....

System-of-Systems Modeling and Analysis The science of System-of-Systems (SoS) is still in its infancy and thus concurrence on a single definition has yet to occur. However, there are common themes among the diverse definitions. The first is the assumption that individual systems must have their own independent operational capability. The...

Technology Management Optimization TMO is an application that builds optimal roadmaps specifying what technologies should be in use and when they should be in use. TMO was developed to allow proactive maintenance and update of technologies for high-valued, long-lived, technologically sophisticated systems. With TMO, all components can be considered as...
