Numerical simulation is one of the most important methods used to study or design protective structures. It is therefore
an important tool for the projects in the VDI programme. However, numerical simulations are difficult, and many questions
still exist. One of the most fundamental questions is: which numerical code is best used? In this report five codes are evaluated
on their ability to simulate high explosive detonations, blast propagation and structural response. The codes considered in this
study are AbaqusIStandard, Ansys, Diana, Autodyn and LS-Dyna. The code Abaqus/Explicit is briefly investigated as well.
All codes are general-purpose engineering software packages that use finite ele- ment (FE) techniques to solve a wide variety
of non-linear dynamic problems. The codes AbaqudStandard, Ansys and Diana solve time-integration with the implicit
method, Autodyn and AbaqusExplicit are explicit codes while LS-Dyna has both implicit and explicit time-integration.

The goal of this brief effort was to determine the feasibility of developing a process that verifies if critical information
system software patches behave as intended and introduce only the specific functionality identified for the patch. Based on our
research, examination and experimentation, we have not only determined that it would be feasible to develop such a process,
but also that this process and associated technology and standards are desperately needed.

Despite turbulent world and economic conditions, some companies continue to thrive in the global marketplace while
others struggle to avoid or emerge from bankruptcy. We believe their secret to success is the successful application and
integration of Supply Chain Management (SCM) principles throughout the entire enterprise. Industry leaders effortlessly
balanced the iron triangle of SCM, the people, processes, and technology that are key to fueling a high velocity supply chain.
The Department of Defense (DoD) lags behind industry in application of SCM principles. We recommend the DoD redefine
its SCM enterprise at the DoD level and provide recommendations to guide the department as it transitions from a state of
awareness about SCM to building an adaptive supply network in the future.
