Equipment Design Integrated Component Selection tool (EDICS) Jim Benfante Ray Seeger December 9, 2003

12/9/2003 Problem: Design of complex piece electronic equipment Proposal design – Base-Of-Estimate (BOE) Actual design – Bill-Of-Material (BOM) Cost estimating – Rough-Order-of-Magnitude (ROM) Conceptual design Short time frame Number of components Electronic module descriptions

12/9/2003 Solution: Provide automated design tool using AI applications and methodologies Provides quick matching of user requirements to available components to satisfy the design requirements. Outputs an electronic file capable of being inserted in existing report formats.

12/9/2003 Final Rule (Making Module Selection) A) Using MATHRULE1 compare (req for Ports) to (inv avail ports) using PORTS1 - ISO1 (where PORTS1 = DigitalIN + DigitalOUT + DigitalIO) (where ISO1 = users linesIsolatedDigital) users req PORTS1, compared to the inventory parameter - portsIO. users req ISO1, compared to the inventory parameter - linesIsolatedDigital. *************************************************************************************** From NARL send the above parameters to a JAVA proc PORTS1 / portsIO = p1 #.### Possable answer a1: a1 = p1(round up to nearest integer) a1 is the number of boards of this type needed for solution. (The inv board with the Min a1 would be the selection.) (p1 exp. 9/4 = 2.25, 9/8 = 1.125, 9/16 = ) (a1 exp. 9/4 = 3, 9/8 = 2, 9/16 = 1 <-) #3? #2? #1 choice? (The selection will be made by COST or LEADTIME )

12/9/2003 Final Rule (Making Module Selection) Possable answer a2: PORTS1 / portsIO = p1 #.### a2 = p1(do NOT round up to nearest integer. Use Modulus function) a1 is the number of boards of this type needed for solution, plus (The inv board with the Min a1 would be the selection.) (p1 exp. 20/4 = 5, 20/8 = 2.5, 20/16 = 1.25) (a2 exp. 20/4 = 5, 20/8 = 2, 20/16 = 1 <--) (From the remainer, nL2 exp. 20/4 = 0, 20/8 = 4, 20/16 = 4) | (with a remainder of 0 no added boards are needed))

12/9/2003 Final Rule (Making Module Selection) Calculate to satisfy the remainder: a2r exp. 4/4 = 1 <--, 4/8 = 0.5, 4/16 = 0.25) Solutions: 1) Q1 from (a2 = 20/16) and Q1 from (a2r = 4/4) <-- #2? choice 2) Q1 from (a2 = 20/16) and Q1 from (a2r = 4/8) <--- #3? choice (4/8 will have unused Ports) The COST and LEADTIME decision may make this choice) Execute MATHRULE2 Execute MATHRULE3 Execute Select Best Comparison (User Input to Inventory)
