Facility layout study. Facility layout and material
Chapter 8, Problem 123SE(choose chapter or problem)
Facility layout study. Facility layout and material flow path design are major factors in the productivity analysis of automated manufacturing systems. Facility layout is concerned with the location arrangement of machines and buffers for work-in-process. Flowpath design is concerned with the direction of manufacturing material flows (e.g., unidirectional or bidirectional; Lee, Lei, and Pinedo, Annals of Operations Research, 1997). A manufacturer of printed circuit boards is interested in evaluating two alternative existing layout and flowpath designs. The output of each design was monitored for 8 consecutive working days. The data (shown below) are saved in the file. Design 2 appears to be superior to Design 1. Do you agree? Explain fully.

Step 1 of 5
We are given the following information regarding the outputs of each of the designs as
shown below:
\(\begin{array}{|c|c|} \hline \text { Designl } & \text { Design2 } \\ \hline 1220 & 1273 \\ \hline 1092 & 1363 \\ \hline 1136 & 1342 \\ \hline 1205 & 1471 \\ \hline 1086 & 1299 \\ \hline 1274 & 1457 \\ \hline 1145 & 1263 \\ \hline 1281 & 1368 \\ \hline \end{array}\)
We need to determine whether design 2 appears to be superior to design l or not.
