Q

Describe the 5 typical process types in goods manufacturing and how these are related to different production layouts.

A

Project Production: Custom work tailored to individual projects, often with high production costs.

One-Off Production: Creating and customizing each product for specific customers, such as in restaurants where products are marketed before development.

Batch Production: Producing products in batches or series, common in both goods and service industries, such as fast food restaurants.

Mass Production: Large volumes of identical products produced efficiently, usually against inventory, like in the automotive industry.

Continuous Production: Very large volumes of a single product are produced in a continuous flow, with significant fixed costs and constant supervision, such as in paper mills.

Q

Explain the differences between professional services, service shops and standard services.

A

Professional Services: Customized by experts (e.g., consultants, lawyers).

Service Workshops: Moderate variation (e.g., auto repair, medical clinics).

Q

Describe the 4 different logics of production flow.

A
  • Convergent Production: Many inputs are turned into a few outputs, like making an airplane.
  • Divergent Production: A few inputs create many different products, like in a steel mill.
  • Hourglass-Shaped Production: Combines many parts into fewer modules that can be assembled in different ways, like engines or cabins.
  • T-Shaped Production: The base product is the same, but it’s customized at the final step before delivery, like a car being tailored with specific features for the customer.

Q

What is the effect of the customer order decoupling point on a production system?

A
  • Definition: The point in the supply chain where production switches from being driven by forecasts to actual customer orders.
  • Impact:
  • Inventory Levels: Determines how much stock is kept.
  • Lead Times: Affects how quickly orders are fulfilled.
  • Production Flexibility: Influences the ability to adapt to changes in demand

Q

What are the differences between stock and made to order?

A
  • stock involves producing and storing goods in advance for immediate sale

-made-to-order produces goods only after receiving a customer order, minimizing inventory but potentially increasing lead times.

Q

Why is capacity a crucial concept in a production strategy?

A
  • The maximum amount a production system can produce in a given times.
  • Why it matters:
  • Meeting Demand: Ensures the system can handle customer orders.
  • Setting Limits: Defines the boundaries for all other operations.
  • Production Level: Represents the highest production achievable.

Q

What does “bottleneck” mean when designing production processes? How does a bottleneck affect a production flow?

A

A “bottleneck” in production design is a stage that limits overall process capacity and slows down production flow, causing delays and reducing efficiency.

Q

Describe some typical supply chains in the production of goods and in the production of services.

A
  • goods: include raw materials, manufacturing, distribution, and retail.
  • services: customer interaction, delivery of the service.

Q

What is a contract manufacturer?

A

A contract manufacturer produces components according to the ordering company’s designs and specifications.

17
Q

What does sourcing mean?

A
  • What it is: Deciding which parts of production to do in-house or outsource.

Why it matters:
- Expertise: Choose based on who does it best.
- Capacity: Consider production limits and capabilities.
- Efficiency: Helps optimize the production process.

18
Q

Describe Kraljic´s matrix for strategic purchasing.

A

Strategic Items

What they are: Very important for profits (impact on profit), hard to get (supply risk).
Focus: Build strong relationships with key suppliers.

Leverage Items

What they are: Very important for profits, easy to get.
Focus: Use your power to get the best deals.

Bottleneck Items

What they are: Not very important for profits, hard to get.
Focus: Make sure you have a steady supply and find backups.

Non-Critical Items

What they are: Not very important for profits, easy to get.
Focus: Keep it simple and use fewer suppliers.

19
Q

Describe the difference between a functional layout and a flow layout in the manufacturing of goods.

A
  • functional layout groups machines with similar functions together in different departments, suitable for small-batch production where products are moved around.

-flow layout arranges machines in sequence according to the production steps, facilitating mass production by allowing products to move through a streamlined assembly line.

20
Q

Explain how the choice of production layout affects the production costs.

A
  • The choice of layout affects costs by influencing how efficiently tasks are performed and how much handling is required
  • functional: Higher costs due to more product movement and setup.
  • flow: Lower costs through streamlined processes and less handling.
21
Q

Describe how flexibility and buffers can be used for managing variation and uncertainty in the production process.

A

Flexibility: Allows changing tasks or having the right people and tools ready.

Buffers: Extra staff or materials to avoid delays.

22
Q

Describe the concept Lean Production

A

-Efficient manufacturing that removes anything not adding value for the customer.

-Focus: Identify what creates value and reduce waste to improve flow.

23
Q

Describe the difference between the two ordering principles push and pull.

A

Push: Production starts based on forecasts or schedules, pushing products through each stage of the process regardless of current demand.

Pull: Production starts based on actual demand, with each stage producing items only when requested by the next stage or customer.

24
Q

What is the relationship between inventory level and replenishment volume?

A

Inventory Level: The amount currently in stock.

Replenishment Volume: The amount added to restock.

Higher inventory levels: Larger, less frequent restocks.

Lower inventory levels: Smaller, more frequent restocks.

25
Q

What is a safety inventory?

A

Safety stock is the minimum buffer level in inventory to prevent shortages of products or materials.

26
Q

Explain the concept Economic Order Quantity (EOQ).

A

the optimal order size that minimizes the total costs of inventory, including ordering and holding costs.

27
Q

What does products in progress mean?

A

Products in progress refer to items that are currently being manufactured but are not yet finished or ready for sale.

28
Q

Draw the typical profile of capital ties up in a manufacturing company.

A

Raw Materials: Initial investment in materials.
Products in progress: Capital invested in partially completed goods.
Finished Goods: Investment in completed products ready for sale

29
Q

In what way is batch size and setup time important for the throughput time of a production process?

A
  • Batch Size:
  • Larger batches: Fewer setups, but longer lead times.
  • Smaller batches: Shorter lead times, but more frequent setups.
  • Setup Time:
  • Longer setup time: Slower production.
  • Shorter setup time: Faster production.
