Objectives of logistics

Costs decreaseCosts decrease Happy customersHappy customers

Improve profitabilityImprove competitive performance

Two key objectives:

Inversely related to one another – cannot accomplish both optimally – trade off between the 2 categories

Decreasing total logistics costs

1.Order processing and admin costs – writing, receiving acknowledgement and processing

2. Inventory related costs –in transit, in storage or WIP

3.Transportation costs – vary depending on mode of transport used, product and size

Trade off between the various cost factors

Improving customer service

Issues:1.When to order (reorder point)2.How much to order (economic order quantity)

Reorder point

Look at:

1.Order lead time

2.Usage rate

3.Safety stock

Reorder point = (Order lead time x usage rate) + safety stockReorder point = (Order lead time x usage rate) + safety stock

Other factors influencing reorder point:

1.Variance of order lead time

2.Fluctuations in C-demand3.C-service standard

Other factors influencing reorder point:

1.Variance of order lead time

2.Fluctuations in C-demand3.C-service standard

Order lead time = 5 days

Usage rate = 200 units per day

Safety stock = 300 units

What would the reorder point of certain stock item be?

EOQ

EOQ = 2DO/IC

D = annual demand in unitsO = cost of placing orderI = inventory carrying cost as percentage of annual inventory investmentC = cost of one unit of the product

= quantity whether the sum of the inventory carrying costs and the order

processing costs are at a minimum

= quantity whether the sum of the inventory carrying costs and the order

processing costs are at a minimum

EOQ = 2DO/IC

Demand = 200 000 units = annual demand = D

Cost of placing one ORDER = R200 per order = O

Unit cost of the product = R25 = C

Inventory carrying cost is 20% of the annual inventory investment = I

EOQ = 2DO/IC





EOQ = EOQ = 2 x 200 000 x 200

Question: When would you have a higher reorder point than usual?

Question: When would you have a higher reorder point than usual?

- Unreliable suppliers- Huge variations in order lead time- Large fluctuations in C-demand

Thus, have to increase safety stocks as well … increased inventory costs …

GROUP ACTIVITY

• Logistics management worksheet

Just in time - JIT

Right products at the right quantities just when they are required.Right products at the right quantities just when they are required.

Information system

KANBAN

Concept that implies that the organisation holds LOW

inventory levels and NO SAFETY STOCK because carrying

inventory tied up working capital.

KANBAN

Coordination between producers and suppliers = essential …

Deliveries are synchronised closely.

NB RE JIT:

1. Close relations between supplier and customer

2. Attention given to quality3. Organisations must have adequate

storing facilities4. Organisations must have adequate

transport options5. Suppliers must deliver a reliable

service6. Short and reliable order lead times7. Purchasing quantities are reduced

Advantages of having JIT:

1. Lower inventory levels = reduced stock holding cost

2. Low/ no safety stock levels = reduced stock holding cost

3. If organisation and supplier have good relationships … leads to higher quality (cannot send back due to time issue)

Disadvantages of having JIT:

1. Risk of running out of stock due to late deliveries

SO – SELECTING SUPPLIERS ON FOLLOWING CRITERIA:

a) Quality of goods they provideb) Their reliabilityc) Their capabilityd) Sound financial positione) Good locationf) Stable labour force

Magical MenagerieThe Magical Menagerie is a magical creature shop that in addition to selling magical creatures also offers advice on animal care and health. The shop is very cramped, noisy and smelly, due to every inch being covered with cages. Among the creatures in the Magical Menagerie are enormous purple toads, a firecrab, poisonous orange snails, a fat white rabbit that can turn into a silk top hat and back, cats of every colour, ravens, Puffskeins, and a cage of sleek black rats that play skipping games with their tails.
