Question

4. In an assembly plant, material handling between departments is performed using a uni-directional closed-loop conveyor. The figure below shows the layout for the modular facility, which consists of three equal-sized assembly modules (A, B, and D), one administrative module (C), and one warehouse module (E). Pick up/Drop off (P/D) points for each module are also shown in the figure. P/D#3 P/D#2 Warehouse module P/D#1 Conveyor flow P/D#4 P/D#5 The distance between P/D points and the number of pallet loads moved between departments are given below. Distance between P/Ds From To Distance P/D1 P/D 2 50 feet P/D 2 P/D 3 75 feet P/D 3 P/D4 25 feet P/D4 P/D 5 75 feet P/D 5 P/D1 50 feet Pallet Flow per Day From/to A B C D A -- 5 0 15 B 10 -- 0 5 C 0 0 -- 0 25 10 0 -- 1. oloo E 30 25 0 10 D Determine the D-score for the current layout.

Answer 1

hswer: Given that : - Pallet flow (day fronto a B e lot T 15 30 I ⓇOW olo o ő i looi oo то from the the given diagram path is E-B- A-D-C. Now, D-score Canbe calculated as below. D score = Edijs qui 5x50 = 250 E-B D score 1315 10x 75 = 750 15x85 = 375 OX 750 o x sono 1375
