Explain the steps to convert an assembly line into a process-based
layout.
-
A fundamental pattern shift is necessary for cellular manufacturing to move
away from
"batch and queue" mass production and toward "one-piece flow,
pull production" systems that are product-aligned. Here are the three steps of
the process.
Step-1 Understanding the Current Conditions.
-
Assessing the current work area circumstances, starting with product and
process data, is the first stage in transforming a work area into a production
cell. Additionally, organizations frequently use value stream mapping to
describe the design and flow of their current processes.
-
The next action is to measure time components, such as cycle time and lead
time needed to transport WIP between processes is the next goal. Another
component is to evaluate takt time in a given period. The recorded
spreadsheets offer a starting point for gauging performance. To evaluate the
viability and performance of a single production cell, it is frequently helpful to
mock one up.
Step-2 Converting to a Process-based Layout.
-
The conversation process includes machines, materials, people, and the
process included with them.
-
An enterprise can swiftly modify a machine or process to generate a different
product type thanks to the single-minute exchange of die (SMED). Because a
single cell and set of tools may create a range of goods without the lengthy
equipment changeover and setup time associated with large batch-and-
queue processes, the business can react swiftly to consumer demand
changes.
-
Organizations often write new procedures for the new layout and train staff
on the new production process after moving the equipment and making sure
quick changeover capabilities are available. Workers from the impacted
processes frequently take part in the conversion process.
Step-3 Continuously Improving the Process
-
After completion of the process it needs improvement. However, the new
arrangement may help in a cycle or lead time still, most processes can be
improved further. Enterprise can work on Equipment failures, Long holds
times, Defects, and Long cycle times.
10.2
What are the tools to leverage teamwork when using cellular
manufacturing?
Why is teamwork so important?
-
Cellular manufacturing requires an organized, clean, and good workplace for
operations.
-
The team working should follow the protocols and regulations of the
respected organizations.
-
Team should be self-focused and dedicated to the process and work as
assigned.
-
The establishment of 5s (Sort, Standardize, Set in order, Sustain, and Shine)
plays a vital role to improve and standardize the workplace for safety and
effective operation.

Why is teamwork so important?
-
The enterprise’s success depends on the hard work of a team. In a cell,
working together had benefits in many ways. Also, several operations are
combined in a sequence. The main job of the people working in the cell is to
maintain a smooth flow. Work will be assigned as per the workflow. Teamwork
has more potential and different personalities with intellectual and positive
mindsets to cope with the problem.
