Five robots in a production line have a 0.95 system dependability rating. R(s)=R1*R2*R3*R4*R5 determines the system's dependability. R(x)=0.9897 since R(x)5=0.95 or 0.95.
Failure rate v/s time is shown by the "bathtub curve." The debugging phase, chance-failure phase, and wear-out phase are its three separate phases.
Waiting is the act of waiting for one process to start while another completes. The flow of operations must be constant and seamless.
If any one of the five components in a series setup fails, the entire system will malfunction. Only if every component operates flawlessly will the system as a whole function satisfactorily.
Ohno is credited as founding the Toyota Production System. In North America, the Toyota Production System idea is frequently referred to as Lean Manufacturing.
The life-test sample plans are failure-terminated when the sample experiences a certain number of failures. Sequential testing and time-terminated tests make up the remaining categories.
Transport refers to the expensive, no-value-added activity of moving a product between production processes. It can also result in product damage. It should be kept as far away from as feasible.
The seven categories of wastes established by Ohno include inappropriate processing, surplus inventory, and wasteful motion. The seven different categories of trash established by Ohno include defects as well.
As the number of components rises, so does the reliability of the system for those kept in series. The system reliability in this instance is always lower than the lowest reliability value of any component.
System reliability is the dependability of the overall system. A system is a grouping of objects like components, units, blocks, subsystems, etc.
If any one of the five components in a parallel setup fails, the system as a whole will also fail. In the event that any one of the parallel components fails, the system will still function satisfactorily.
As the number of components rises, so does the reliability of the system for components maintained in parallel. The system dependability in this instance is consistently higher than the highest reliability rating of any component.
After a year, the system's reliability is determined by R(s)=R1*R2*R3*R4. So, R(s)=0.9*0.9*0.8*0.8=0.5184.
Andon is a system of visual and/or auditory communication that signals when assistance or attention is required in an activity. It might be a rope, a lamp, or a flag.
Muda Type 1 includes, for instance, inspection and safety testing. Despite having little value to add to the finished product, they are necessary for the client.
Given by R(s)=R1*R2*R3*R4*R5, the system's dependability can be calculated. R(s) = 0.95 * 0.95 * 0.95 * 0.95, or 0.7737.
