GENERAL PRESENTATION
1.1.
INTRODUCTION
SIMLOG is a computer aided evaluation which helps the logistician develop Integrated
Logistic Support Elements for one or several repairable complex systems.
A support system corresponds to a set of support elements, the main components of
which are represented on the following drawing:
Handling/Packaging
Transporting/
conditioning
Provisioning
Spares
Computer
Man power and
Technical
Assistance
Logistic Support
Elements
Maintenance Plan
Training
Technical Documentation
Infrastructures
Test/Support
Equipment
Figure 1: Integrated Logistic Support Elements
Every support element is an homogeneous component which can be:
the supplying of an hardware component (spare, support equipment),
o
o a service (training, manpower...),
o a data or information supply ( technical documentation, maintenance plan).
These support elements are essential and do exist for every system. They represent
important costs and do necessitate a perfect knowledge of logistic informations.

FUNCTIONAL STRUCTURE OF SIMLOG
SIMLOG is the Integrated Logistic Support tool which has been developed and
maintained by our engineers. The interface with SIMFIA is possible, but SIMLOG can
be used independently.
SIMLOG has three applicatives modules:
OPTIM-STOCK
COST
SIMLOG
central core
*
LORA
Figure 2: Functional structure of SIMLOG
o The CENTRAL CORE allows the description of the system equipment and the
associated support system.
o OPTIM-STOCK is an optimization module which allocates the optimal initial spares.
o COST is the generator of Life Cycle Cost models.
o LORA is the Level Of Repair optimization model (in project).

General Specifications
The general characteristics of the softwares developed by SOFRETEN engineers are
following:
- Reliability/Performances:
The algorithms used in SIMLOG have been validated and optimized by Research
Centres. Our R & D team always integrates the State of the Art of the most recent
approaches and technologies, to be able to adopt the most recent theoretical and
practical technics in SIMLOG.
- Human Engineering / Graphic tools:
The user is continuously assisted by clear menus. SIMLOG uses all possibilities of
Windows (Mouse, colors, zoom,...).

1.4. SIMLOG : EVALUATION TOOL
Using data related to systems, SIMLOG allows to evaluate Reliability, Maintainability
and Availability characteristics, concerning the whole system, as well as each of its
components (called « items »).
For a certain configuration of the support system, SIMLOG evaluates different output
data which are unavoidable for the logistician to perform his choices, as well as the:
investment costs related to the initial spares,
o
o operational performances characteristics of the operational sites, the systems,
and their components,
o PNRS ( Probability of Not Running out of Stock) for a given duration of
mission, or for a transitory phase;
o average spares demand.
SIMLOG thus allows the user to obtain simulated situations. Provoking different
variations of the input parameters, he can perform comparative analyses.
Through the module COST, SIMLOG is a generator of Life Cycle Cost models. The
user design the Cost Breakdown Structure . At each leaves of this tree the user gives
the formula to be used for computation and the dependencies with the system
equipment or support system:
o Sites
o
Item
o Personnel
o Technical documentation
o Test and support equipment
o Consumable
o Year
Results can be visualized through different projections:
o Time projections: All or a part of the Life Cycle
o System equipment/ Support system projections
