Operation’s Management 2301
Since each product require different processes.
We group people to do similar job and also bring machine do the same job
Example: Different job for different companies.
Problem: different product different department so there might be arrangement
Step 2: they all need to be processed by the printing department if this department is
temporary overload so
Its decrease the capability of
Solution: oversee or they have people in other department they can move people from
other department, which have less load in order to reduce the load
• Used when a moderate volume of goods or services is desired.
• The equipment need not be as flexible as job shop
• Processing is still intermittent.
Moderate: we could have some specialized machines
Example: small company don’t have that specialized machines
They can give different ingredient through different machines
Processes are different
• Is used when higher volumes of more standardized goods and service are
• Other names:
We can combine models for different products
Different cpu different hardware to make different product
This kind of production process is more structured
Example: Suzuki factory
2 second to produce a car
Modules change those models and make different product and those models and
equipment made before making the final product
• Used when a high volume of highly standardized output is required.
Highly automatic system
Produce standard output Example: Duct paper production
Major difference between duct tape and Suzuki: All machines in duct tape no labor
Don’t need workers on the production lines
You need workers to monitor the production
They don’t do the job of making the product just to control the production
Utilization of your machine will be very high.. Machine is continuously working on
the product its exactly opted to job shop overall utilization in job shop is very low its
Continuous has very limited product variety
Machinery that has sensing and control devices that enables it to operate
Today computers and advanced techonology has given us more advanced varieties of
Very rigid , uses high cost, specialized equipment for a fixed sequence of operations.
Based to perform one or two fixed tasks
Works well in
Problem: we need to produce some very complicated product , its too expensive,
inflexible not able to do complicated jobs.
Uses general purpose equipment controlled by a computer program
Numerically controlled machines
Example: Toyota Camry Hybrid Factor Robots
If you give those robots different programs they can do different jobs.
Uses equipment that is more customized than that of programmable automation
Flexible manufacturing systems (FMS), Computerintegrated manufacturing (CIM)
Can quickly change jobs can quickly change from one job to another.
All three automation have different definition but in practice they have some
Flexible Manufacturing systems:
FMs are more fully automated versions of cellular manufacturing: A computer
controls the transfer of parts from machine to machine as well as the start of work at
Produce a variety of similar products.
Example: CNC Flexible Manufacturing System
Totally automatic production line
A system linking a broad range of manufacturing activities through an integrated
Notes: Connect realtime production line system
More advanced than flexible advanced system
Difference between flexible
Theoretical difference but they are same in real life.
Flexible is only automatic production line
CIM create real time production system
Classification of production systems and types of layouts:
The configuration of departments, work centers, and equipment, with particular
