PIONEER provides a flexible modelling system with which users can create both reusable
model definitions and specific instances of models. PIONEER is delivered with a
comprehensive library of models and there is no limit on the number of fully user-configurable
models which can be added. Model outputs can provide values for all key data in
PIONEER including failure likelihoods and durations, serviceability costs and intervention
benefits.
Models can be created in the following forms:
Calculation Tree - used for complex algebraic model formulations
Decision Tree - qualitative and quantitative data classification models
External Function - load external models written in any .NET language into PIONEER
Lookup Table - model output derived from processing asset data through multi-column
lookup tables
User-tabulated Distribution - user-defined distributions for failure durations,
consequences etc.
In addition, PIONEER comes with a library of read-only mathematical models and statistical
distributions covering a wide range of applications. Users are able to add to this
library by creating External Function models (see below).
External Modelling
External Function models allow DLL files written in any .NET language (C#, VB.NET,
C++/CLI etc.) to be used directly within PIONEER. The PIONEER installation CD
supplies DLLs and interfaces which simplify the process of creating a PIONEER-compatible
DLL.

FAILURE MODES
PIONEER uses Failure Modes as a way of modelling the manner in which an asset can
fail and its failure characteristics. A powerful 'Applies To' system allows Failure
Modes to be defined by users for assets which match user-specified criteria.
Examples
Failure modes are fully user-defined and can be used to represent any asset failure
which may be experienced; for example:
Public sewer blockage
Water main burst
Pump failure
Failure Characteristics
Failure Modes contain an extensive set of characteristics which can be defined for
a failure, including:
Whether the asset would be repaired or replaced when it fails
Failure consequences based on Serviceability Indicators
Duration of the asset failure
Duration of the impact on serviceability
Time-dependent likelihood of failure
Costs incurred as a result of failure, both direct and social and environmental
costs
Costs of asset repair, replacement and refurbishment

ANALYSIS SETUPS
Analysis Setups provide a method of evaluating new data setups and creating alternative
scenarios without affecting the base data.
Testing New Data
Key data in PIONEER is created within Analysis Setups, which can be copied to provide
alternative versions. Changes can be implemented and tested in these alternative
versions. Successful changes can be replicated in the original data; unsuccessful
changes are simply discarded, leaving the original data intact. Any changes to the
original data are replicated in all copied versions, ensuring that all alternative
data remains relevant.
Alternative Scenarios
There is no limit on the number of alternative data copies that can be generated,
meaning that users can define generic data in a Base Analysis Setup and then create
copies which can be tailored for specific scenarios.
