Q2: A customized box assembly consists of a base, a top cover, four sides, and two handles. Table 1 shows the processing sequence required by each part, and Table 2 shows process information assuming equal process times for all parts at any given operation (Example, painting a cover, or a base, or a handle, or the side takes 0.3 hours). If the demand on the box is 500 units per the 8 hours shift,

Table 1
Part	Operation Sequence	Parts/box
Cover	1 2 3 4 7	1
Handle	1 3 2 6 7	2
Side	1 3 4 5 6 7	4
Base	1 3 4 5 7	1
Table 2
Op. #	Op. Descriptions	Hr/part	Reliability	Efficiency	% Scrap
1	Shear	0.1	0.80	0.95	2
2	Chop	0.15	0.85	0.95	2
3	Punch	0.05	0.90	0.92	1
4	Form	0.2	0.95	0.85	3
5	Rivet	0.1	0.90	0.98	1
6	Paint	0.3	0.95	0.95	1
7	Assembly	0.1	0.95	0.95	1
