## Problem 1
|
|
|
|
Fill in the blanks in the following assembly-line scheduling example.
|
|
|
|
### Solution 1
|
|
|
|
|
|
|
|
|
|
**table $s$**
|
|
|
|
| $s$ | 1 | 2 | 3 | 4 | 5 | 6 |
|
|
| --- | --- | --- | --- | --- | --- | --- |
|
|
| 1 | 9 | 18 | 20 | 24 | 32 | 35 |
|
|
| 2 | 12 | 16 | 22 | 25 | 30 | 37 |
|
|
|
|
**table $l$**
|
|
|
|
| $l$ | 1 | 2 | 3 | 4 | 5 | 6 |
|
|
| --- | --- | --- | --- | --- | --- | --- |
|
|
| 1 | - | 1 | 2 | 1 | 1 | 2 |
|
|
| 2 | - | 1 | 2 | 1 | 2 | 2 |
|
|
|
|
$$\begin{align*}s^* &= 38\\l^* &= 1\end{align*}$$
|
|
|
|
## Problem 2
|
|
|
|
Fill in the blanks in the following pseudocode for assembly-line scheduling
|
|
|
|
### Solution 2
|
|
|
|
```python
|
|
FASTEST-WAY(a, t, e, x, n)
|
|
s[1][1] = e[1] + a[1][1]
|
|
s[2][1] = e[2] + a[2][1]
|
|
for j = 2 to n
|
|
do
|
|
if s[1][j-1] + a[1][j] <= s[2][j-1] + t[2][j-1] + a[1][j]
|
|
then s[1][j] = s[1][j-1] + a[1][j]
|
|
l[1][j] = 1
|
|
else s[1][j] = s[2][j-1] + t[2][j-1] + a[1][j]
|
|
l[1][j] = 2
|
|
|
|
if s[2][j-1] <= s[1][j-1] + t[1][j-1]
|
|
then s[2][j] = s[2][j-1] + a[2][j]
|
|
l[2][j] = 2
|
|
else s[2][j] = s[1][j-1] + t[1][j-1] + a[2][j]
|
|
l[2][j] = 1
|
|
if s[1][n] + x[1] <= s[2][n] + x[2]
|
|
then s* = s[1][n] + x[1]
|
|
l* = 1
|
|
else s* = s[2][n] + x[2]
|
|
l* = 2
|
|
