A. Collection
Connects to automated, semi automated and manual
production to count and collect data with minimal or no human
intervention.
B. Display
Presents relevant production information back to operators,
line leaders, supervisors, the supporting departments and the
management. Seven segment display panels have become the
method of choice of many industries because they can combine
the benefits of color with the numerical values.
C. Analysis
Should provide sufficient production data for the
management to conduct relevant analysis at all level in the
shop floor.
Cycle time
This is the time-span for the specific parts or items to be
produced. This is usually set by the production planning and
control department (PPC) after a time study on the process is
done. The process cycle time will be programmed into the
PLC.
Planned stop
This is the length of time during which there is production.
This is when the workers have no productivity as planned by
the management. A switch will be used to generate pulses for
the display to capture the duration of no productivity.

Maintenance
When a fault is detected due to machine or technical failure,
the operator has to press the switch to alert the department and
at the same time the display will capture the time taken to
solve the fault.
Others
This display is used to capture the length of time taken by
outside vendors on their duration of work on production lines.
This could be an improvement process or system upgrading.

VIII. CONCLUSION
C. Supervisors
PMS also benefits the supervisors and the line-leader
whereby it act as a supervisory tool, which enables the
movement of people (operators) from one job to another when
operators are absent or unable to meet production
requirements. Such a display system helps the supervisor to
monitor the performance of their production lines by referring
to the parameters displayed. This will help them to keep the
production output back on track to meet set goals within the
planned production duration. The process flow of the PMS is
shown in Fig. 5 illustrates the task of the supervisor (level 3).
D. Production team
The proposed PMS helps the production team to ensure
production goals to be established and monitored continually.
Apart from that PMS also helps to increase production at
controlled production costs, at all levels of work force, within
the set targets and enable continuous improvement of line
balancing (bottle neck). PMS helps to screen the work
progress and creates awareness when work is not flowing, i.e.
it sustains the required production output. The process flow of
the PMS as shown in Fig. 5 which illustrates the chore of the
production team (level 2).
E. Management
All production related information is presented to the
management and supervisors via display boards. These
eliminate the clerical error which makes reporting easier
compared to conventional methods. Relevant production
information can be generated base on the industry requirement
and this will help the management to summarize throughput,
work in progress, stock information (produced parts) and
work around solutions as problems occur. From the data-base
the management can also eliminate bottlenecks, unwanted
wastage and production interruption.
As a result of the analysis the managements can make
counter-measures to ensure better efficiency and capitalize on
the available resources for generating better production yield.
The process flow of the PMS as shown in Fig. 5 illustrates the
task of the management (level 1).
