By What is the difference between flow shop and job shop?
If your products move through a linear, unchanging sequence of steps — with one operation per machine — you probably have a flow shop. If your products move from machine to machine in a manner that you could call “all over the place” you might have a job shop. Or you might have another type of shop entirely.
What is a job shop layout?
Layout. In the job shop, similar equipment or functions are grouped together, such as all drill presses in one area and grinding machines in another in a process layout. The layout is designed to minimize material handling, cost, and work in process inventories.
What is an example of a flow shop?
The Flow Shop In a flow shop, the processes are arranged in the sequence that the parts are processed. The best known example is the assembly line, but there are many others. This type of production system is usually the ultimate goal of any lean system.
What is the difference between job shop and continuous process flow structures?
A job shop process uses general purpose resources and is highly flexible. A flow shop process uses specialized resources and the work follows a fixed path. Consequently, a flow shop is less flexible than a job shop.
What is Flow Shop Scheduling with example?
Flow shop scheduling is a special case of job scheduling where there is strict order of all operations to be performed on all jobs. Solution methods of Flow shop scheduling are Branch and Bound, Dynamic programming, Heuristic algorithm and Meta-heuristics.
What is flow shop process?
It is a form of facility setup, and is also called Line Layout. This refers to the process or shop which, when all works (jobs) have the same processing route, is set up based on the flow. This is useful to the repeated production which has the fixed job flow and a relatively large quantity of production.
Is the advantage of job shop process?
Advantages of job shop production : The opportunity exists for creative methods and innovative ideas. Large inventory of material, tools and parts. Easy of supervision. High utilization of expensive machines.
What is a flow shop process?

What are the 4 types of processes?
1) Three or the four types of processes are: B) goods, services, and hybrids. Processes are the ways in which an act is carried out.
How can we make scheduling in flow shop?
Solution methods
- Form set1 containing all the jobs with p1j < p2j
- Form set2 containing all the jobs with p1j > p2j, the jobs with p1j = p2j may be put in either set.
- Form the sequence as follows: (i) The job in set1 go first in the sequence and they go in increasing order of p1j (SPT)
What are the 3 methods of production?
There are three main types of production to choose from:
- Job production, where items are made individually and each item is finished before the next one is started.
- Batch production, where groups of items are made together.
- Flow production, where identical, standardised items are produced on an assembly line.
What are the advantages and disadvantages of job shop?
Production and operations: job production
| Advantages | Disadvantages |
|---|---|
| Product usually high quality | Cost of producing one unit or job is higher |
| Producer meets individual customer needs | Labour –intensive |
| Greater job satisfaction – involved in all stages of production | Requires investment in skills and training |
