Project Prioritization.

The development of innovative software for a Project Prioritization System, which develops a new methodology and accompanying software to help evaluate the hundreds of candidate projects distribution managers typically need to compare.
Aging Assets/ Repair Replace.
Development of software for a Repair/Replace strategy for Aging Assets. The objective is to produce a least cost strategy for utilities to help increase reliability and reduce financial risks as equipment reaches the end of expected life.
Area Investment Strategy Model.
Development of software and methodology for an Area Investment Strategy Model to help utilities define a capacity expansion plan given uncertain load growth in an area.
Delta Model.
Development of software to help analyze the impact of deferral by using distributed generation capacity.
The project involved developing a Prolog based platform for Electric Power Research Institute’s EPRIGEMS platform. The user interface is fast, attractive, easy to use and has some intelligence to direct the user on what to do next.
SBSI developed an attractive and an easy to use EPRIGEMS interface that integrated Battelle’s
FOWL code with H.E.L.P. H.E.L.P. develops rainfall information and FOWL is a Fossil Waste
Leaching Model. In addition, the original H.E.L.P. Fortran code was completely rewritten in C.
Various tools were developed for use by EPRIGEMS developers. The tools allowed the developers to display bit-mapped graphics, provide high level routines coupled with IMAGINE to quickly develop EPRIGEMS applications, and provide a clipboard under DOS.
GWQA – Groundwater Quality Advisor (EPRIGEMS).
This EPRIGEMS software package released by EPRI integrates EPRI’s FOWL and MYGRT software. Besides the modeling capabilities it has extensive hypertext help incorporating graphics. It was one of the first released EPRIGEMS software packages.
CHROMAT–EPRIGEMS Interface and New Numerical Routines.
SBSI developed an attractive and easy-to-use user EPRIGEMS interface integrated with the original Fortran code for examining Chromat Attenuation. The interface includes a database for keeping track of samples.
An EPRIGEMS interface was added to EPRI’s SITES model.
SBSI developed an attractive and easy-to-use user EPRIGEMS interface combined with a database, report, and graphing modules to work with the Electric Power Research Institute’s (EPRI’s) Selenium Model code. The original code was translated from Fortran to C.

UFIM – EPRI’s Utility Fuel Inventory Model.
SBSI transferred EPRI’s mainframe Utility Fuel Inventory Model to the IBM PC/AT. For better
performance in the PC environment, the following were done:
  • Sections of the model code were rewritten to be numerically stable.
  • The Linear Equation Solver was replaced by a new version that is numerically stable, fast and uses less memory.
  • The mainframe code requires approximately 4 megabytes to run. The code was modified so that it can run on a microcomputer with 640 Kbytes.
  • A front end was added to the model so that the model works through a screen oriented user interface that accesses the model data through a database rather than through file names.

On a new contract, UFIM was completely recorded so that it works more efficiently on both mainframes and PCs. The original contract was to “hack” around the original existing code and speed it up some. The recording of EPRI’s UFIM model has resulted in:

  • Faster executing code.
  • Better structured code.
  • Numerically stable code.
  • Memory efficient code.

In addition to the recording, an EPRIGEMS interface was added to the code.

TCM – EPRI’s Technology Choice Model.
An attractive and easy-to-use interface was developed in Pascal for EPRI’s Technology Choice Model on the PC. The interface displays and requests complex information about tree structures in a simple, consistent way. Once all the data has been entered the user can interactively execute sections of the model, which uses multi-attribute utility function theory to analyze decision alternatives. The model is currently being Beta-tested at selected sites. A full production version from EPRI will be available shortly.

The TCMPC model has a number of nice capabilities:

  • It provides for a smooth interaction between user entered data and analysis of results.
  • Includes a database as well as allows multiple databases.
  • Incorporates graphics.
  • And, incorporates attractive reports.

PCBFIRE – PCB Fire Simulation Model.
This is a simulation model that is designed to simulate PCB leakage in a building. The model helps in the assessment of exposure to PCB fire. SBSI developed the Ordinary Differential Equation solver and added an attractive and easy-to-use user-interface.

The model makes use of the Runge-Kutta fourth order adaptive method to solve the PCB Fire model ordinary differential equations. The user can override this and choose from the following methods: Runge-Kutta second order fixed step, Runge-Kutta fourth order, Runge-Kutta fourth order adaptive methods and the Burlisch-Stoer method. The default method is Runge-Kutta second order fixed step.

REPGEN–A Report Generator for EPRIGEMS.
REPGEN is a report generator developed for EPRIGEMS to allow easy generation of the script files used as input by the r-tree report writer. The software enables the user to create r-tree script files without having to learn the details of r-tree syntax.
SBSI developed an attractive and easy-to-use Net Impression Model for Pacific Consulting Group(PCG). The model is used by PCG in a large part of their consulting work.
