CASE $2$:

CAPACITY PLANNING AND HYBRID LAYOUT

$($Batch Production$)$

Design a manufacturing system for batch production of three different products $($in

$256$ workdays per year$).$ Routings and machines for the products are following:

$1^{st}$ product $(x)$ : $,$ production costs $35$ EUR$/$part$,$ quantity $4100$ parts$/$year

$2^{nd}$ product $(Y)$ : $,$ production costs $70$ EUR$/$part$,$ quantity $3300$ parts$/$year

$3^{rd}$ product $(Z)$ : $,$ production costs $40$ EUR$/$part$,$ quantity $1600$ parts$/$year

Machine areas $(WL)$ for each type $($all in $mm)$:

A: $16003800$

B: $14002900$

C: $11003300$

D: $12002000$

$E$:$10002500$

$($add serving and maintenance areas!$)$

Maximal transport batch is $60$ parts $($for all product types$).$ Average working hour

costs on the machine is $31EU\frac{R}{h}$; annual interest rate is $12\%.$ Planned facilities

utilisation is $78\%.$

Plan the necessary capacities, design the theoretical layout of the plant and draw the

final plant layout using real areas of machines, transport paths etc.!
