Starving- The assembly operator completes the work on current unit and starves for next unit work as it has not arrived yet at the station, this is called starving.
Blocking- Blocking is where the operator completes the work but still couldn’t move on to the next unit as the worker is not ready to receive it.

The proportion of theoretical cycle time to actual average production time when downtime on hold is found the middle value of in is called Line efficiency.
15.9
Cycle time- The time needed for arrival of work units at a station is the cycle time.
Service time- The time needed to complete the task at the station is the service time.

Precedence constraints are confinements on the request in which the work components can be performed. A few components must be done before others.

The number of workers per station is the manning level and when it comes to the entire line, it is the division of total number of workers on the line by number of stations.

A pallet fixture is a workholding gadget that is intended to (1) installing the part in an exact area in respect to its base and (2) be moved, located, and precisely braced in position at progressive workstations by the exchange framework.

A dial-indexing machine is a mechanized framework comprising of various workstations that procedure workparts joined to apparatuses around the fringe of a circular worktable which is listed to position the parts at the stations.

Geneva mechanism is used to provide rotatory motion.

The parts are collected and stored temporarily in a location called storage buffer before downstream.

Industrial Applications of automated production line
I have to pull two alleles (two straws) from the bag to represent one fish because fishes like humans get two alleles one from their father and one from their mother.
Whenever work breakdown structure come play, it basically saying or telling how work is broken down into smaller units such that whatever that has been put under a particular unit can be understood by the team members.
That is for a spring the time taken for it to move to and fro once is
13.16 The reliability of a hard-disk drive is typically described in tems of a quantity called mean time between failures (MTBF). Although this quantity is call a “time”, the MTBF is measured in drive-hours per failure.
Whenever a work breakdown structure come play, it basically saying or telling how work is broken down into smaller units such that whatever that has been put under a particular unit can be understood by the team members.
...of motion (T), measured in seconds and milliseconds. Time is recorded for five periods and averaged (T=t/5). Repeated five times for each length and averaged.
Essential objective of any manufacturing industry to accomplished the high level of throughput, ability to respond efficiently according to the changing demands of the consumers. System utilization computed as a percentage of the available times (number of the machines accessible for generation reproduced by the quantity of changing so as to work hours), it can be increased by changing in plant layout, by diminishing exchange time between two stations and throughput, defined as the number of parts delivered by the last machine of a manufacturing system over a given duration of time; Groover, M. P., (2008)
The capacity of a production line depends on the average efficiency of the line and operator absenteeism. For example, a factory floor has 5 lines. Factory works for 8 hours day. Number of total
* critical ratio assists in: decides what production point a job is at, regulates job
Time: Time is simply how long each session lasts, which will change based on the intensity and type of session.
It is also known as input process. It can be defined as the process of arrival of customers in the system.The arrival pattern in queueing system is measured by the mean arrival rate or mean inter-arrival time.
Maintaining the operating equipment at a responsive level to the need of production in terms of delivery schedule and quality.
Over time, the word “queue” has been developed to hold several meanings, some of which are more commonly used than others. Although it may have more than one meaning, it is commonly believed the word only contains one use. However, the word is capable of describing several objects in the English language.
Shutdown improvement maintenance: improve the maintenance activities while the production line is completely shut down.
