3. DESCRIPTION OF PROGRAM OR FUNCTION - AES (Automated Estimating System) enters and updates the detailed cost, schedule, contingency, and escalation information contained in a typical construction or other project cost estimates. It combines this information to calculate both unescalated and escalated and cash flow values for the project. These costs can be reported at varying levels of detail. AES differs from previous versions in at least the following ways: The schedule is entered at the WBS-Participant, Activity level - multiple activities can be assigned to each WBS-Participant combination; the spending curve is defined at the schedule activity level and a weighing factor is defined which determines percentage of cost for the WBS-Participant applied to the schedule activity; Schedule by days instead of Fiscal Year/Quarter; Sales Tax is applied at the Line Item Level- a sales tax codes is selected to indicate Material, Large Single Item, or Professional Services; a "data filter" has been added to allow user to define data the report is to be generated for.


4. METHOD OF SOLUTION - Average Escalation Rate: The average escalation for a Bill of is calculated in three steps.
1. A table of quarterly escalation factors is calculated based on the base fiscal year and quarter of the project entered in the estimate record and the annual escalation rates entered in the Standard Value File.
2. The percentage distribution of costs by quarter for the Bill of Material is calculated based on the schedule entered and the curve type.
3. The percent in each fiscal year and quarter in the distribution is multiplied by the escalation factor for the fiscal year and quarter. The sum of these results is the average escalation rate for that Bill of Material.
Schedule by curve: The allocation of costs to specific time periods is dependent on three inputs, starting schedule date, ending schedule date, and the percentage of costs allocated to each quarter.
Contingency Analysis: The contingency analysis is based on cots categories at the WBS-Participant level with regard to the completeness of design and degree of difficulty.


5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM - A single schedule activity is limited to 40 years.


6. TYPICAL RUNNING TIME - The running time is dependent upon the size of the function being performed.


7. UNUSUAL FEATURES OF THE PROGRAM - Ease of use: AES uses menus and formatted input screens to guide the user through the estimate creation/update process.

ESTS0165/03:

(AES-6.0F):The standard value file is created or updated in a separate program, STDVALUE. This feature allows this file to be centrally maintained and distributed when many users are working on the same project. This ensures that all estimates use consistent information.

11. MACHINE REQUIREMENTS - 385 KB of free Random Access Memory (RAM), color graphics monitor and adapter, one 720 KB diskette drive, one hard disk drive (either fixed or removable) with at least 3M of free disk space, printer.

ESTS0165/03:

The program was installed at NEA-DB on a DELL 560/L PC/80486(66MHz) with 16MB of RAM.


12. PROGRAMMING LANGUAGE(S) USED -
ESTS0165/03: PASCAL 


13. OPERATING SYSTEM UNDER WHICH PROGRAM IS EXECUTED - DOS 3.1 or higher. 

ESTS0165/03:

 The test cases were executed at the NEA-DB under MSDOS6.2. 


14. OTHER PROGRAMMING OR OPERATING INFORMATION OR RESTRICTIONS - At the time the computer is booted, a file named CONFIG.SYS must be in the root directory of the drive from which the system is loaded. The file must contain at least the following lines. FILES = ff, BUFFERS = bb, where ff must be at least 13 and bb must be at least 10. AES6 incorporates some codes which accompanies the Turbo Toolbox software package. It is permissible to distribute the object code of these routines with a production system. The source code cannot be distributed due to license restrictions from Borland International, Inc. If errors are encountered during compilation, turn off the strict variable checking in passing parameters. Source code is not included with package.
