Manufacturing strategies Flashcards
Functional layout (jobshop)
- machine oriented
- sequence flexibility
- many different products in small volymes
Fixen position
- construction-, power- and ship building
- few products (one piece)
- production system special for each project
- generic and flexible equipment
Batch flow
- product oriented
- high value added in the group
- few products, few variants in higher volumes
Line flow
- product oriented
- masa production, even and high demand
- machine or operator controled
- Low flexibility, dedicated equipment
Continuous flow
- high level of automation
- physically linked units
- production measured in tons, liters, meters etc.
- limited production range
Choice of production system
- product: volumes and number of variants
- available space
- existing production/system
- manufacturing strategy
Costomer order decoupling point (codp)
The point which splits the flow into two parts: what is produced on expectation, on forecast, and what is produced for a specific customer order.
MTS
Make To Stock.
ATO
Assembly to order
MTO
Make to order
ETO
Engineer to order
Strategies
Business strategy, marketing strategy, product development strategy and manufacturing strategy. See figure.
Manufacturing strategy
Manufacturing strategies comprise a series of decisions concerning process and infrastructure investments, which, over time, provide the necessary support for the relevant order-winners and qualifiers of the different market segments of a company
TTM
Time to market, develop and introduce new products
TTC
Time to costomer, delivery of existing product range
Performance objektive
Spindel diagram. Cost, dependability, flexibility, quality and speed.
Cost
The cost of material, Labour, and other resources to produce a product. Measured in: - unit production cost - cost relative to competitors - manufacturing cost - total factor productivity - direct labour - inventory
Quality
The manufacturing of products with high performance and comformance. Measured in: - number of complaints - warranty returns - percentage scrap - scrap and rework cost - incoming supplier quality - mean time between faliure - rework cost
Speed
Speed of delivery. Measured in: - cycle time - vendor delivery time - response time - system throughput time
Dependability
The reliability of delivery. Measured in: - percentage on time delivery - average lateness - proportion of products in stock - mean deviation fr.o.m. Promised arrival
Flexibility
The ability to react to changes in volume, changes in product mix, modifications to design etc. Measured in: - set-up time - time needed to develop new products - range of products - time to change schedules - minimum order Size - number of options - percentage workforce Cross trained
The operation strategy Matrix
A Matrix with the performance objektives on one side and the decision areas on the other. This resultat in market competitiveness. Made by slack and Lewis
Operation strategy decision areas
Capacity, supply network, process technology and development and organisation
Trade-offs
There is ni suck thing as a free meal/ you cant have it. all.
