(Problem after bottleneck)
P. 276 in the book
Problem:
D= OT / CT
CT opt = 1.6
CTmin= 1.2
CTmax= t = 4.4
3. Number of stations:
Nmax= t / CTmin = 4.2 / 1.2 = 3.5 = 4
Nmin= 4.2 / 4.2 = 1
Nopt = 4.2 / 1.6 = 2.62 = 3
1.6 1.6 1.6
A 0.3
C 0.4
e. 0.2
g 0.1
b 0.6
d. 1.2
F 0.6
H 0.5
Idle = 0 idle = 0.4 idle = 0.2
Efficiency = Available time / Actual time = t / N.CT = 4.2 / 4.8 = 87.5%
If N= 1 Efficiency = 100%
If 4 Stations:
1.2 1.2 1.2 1.2
A 0.3
B 0.6
D 1.2
C 0.4
E 0.2
F 0.6
G 0.1
H 0.5
I 0.3
Idle = 0.3
Idle = 0
Idle = 0
Idle = 0.3
Efficiency: t / N.CT = 4.2 / 4x1.2 = 4.2 / 4.8 = 87.5%
6. Comment:
Compare the three solutions and choose the best number of stations.
D = OT / CT = 440 / 1.2 = 307 units
Therefore, the 3 stations is better because it produces enough units for the demanded quantity, the
4 stations will produce more (307) but we don’t need them

Management = POLC
P= Plan = 5Ws: Why keep inventory?, what, where, when,
O= Organise = handling, logistics, shelving, shelf life,
Leading / directing of staff, suppliers,
C= Control inventory: this class
Inventory: A stock of goods
Independent demand: demand on my final products (from customers)
Dependent demand: demand on parts of products (from production department)
Types of inventory:
- Raw Materials and Purchased parts
- Work in progress
- Replacement parts, tools & supplies
- Good in transit
- Finished goods inventories
Function of Inventory:
Main purpose of inventory is to keep the production running Continuity
Inventory Counting System:
Periodic System: Physical count each fiscal year
Perpetual System:
Universal bar code:
Lead time= time from order till receiving the order
Holding cost: cost u pay per unit annually to keep the product in house
Ordering / set up cost: cost of the purchasing process (from decision to buy till goods are received)
Shortage cost
ABC Classification System:
EOQ Model: Economic Optimal Quantity
Advised to manage critical inventory only.
Only 1 product, annual demand known, demand even each year, ……
Fig 11.2:
Reorder point depends on the lead time, the shorter the lead time the less the reorder point.
Total cost: Annual carrying cost + Annual ordering cost
