As below.

Explanation:

Answers to a), b), c), d) seem to be correct.

e) Theoretical time taken for making 12 donuts :

  1. dough mix = 8 min
  2. Place dough in form @ 6 donuts in 2 min = 2 * 2 = 4 min
  3. Form in oven @ 6 / 12 min = 2 * 12 = 24 min
  4. Cooling time = 3 min
  5. Payment and packaging = 1 min

Total theoretical flow time = 8 + 4 + 24 + 3 + 1 = 40 min.

f) 1. With oven capacity - 1 doz donuts.

i) Dough mix = 8 min
ii) Placing dough in form = 2 * 2 = 4 min min
iii) Form oven @ 12/ 12 min = 12 min
iv) Cooling time = 3 min
v) packaging and payment = 1 min

Theoretical flow time = 8 + 4 + 12 + 3 + 1 = 28 min.

f) 2. Another oven with 6 donuts capacity.

i) dough mix = 8 min
ii) Placing dough in form = 2 * 2 = 4 min
iii) Form oven @ (6 / 12 min ) * 2 = 12 min, as both ovens will function simultaneously.
iv) Cooling time = 3 min
v) Packaging and payment = 1 min

Theoretical flow time = 8 + 4 + 12 + 3 + 1 = 28 min.

f) 3. Replacing the oven with convection one :

i) Dough mix = 8 min
Placing dough in form = 2 * 2 = 4 min
iii) Form oven @ (6 donuts / 6 min) * 2 = 12 min
iv) Cooling time = 3 min
v) Packaging and payment = 1 min

Theoretical flow time = 8 + 4 + 12 + 3 + 1 = 28 min.

g) same as f) 3. = 28 min.
