Overall equipment effectiveness [1] (OEE) is a measure of how well a manufacturing operation is utilized (facilities, time and material) compared to its full potential, during the periods when it is scheduled to run.
In operations research, Johnson's rule is a method of scheduling jobs in two work centers. Its primary objective is to find an optimal sequence of jobs to reduce makespan (the total amount of time it takes to complete all jobs).
OLE also accounts for labor utilization. Understanding where downtime losses are coming from and the impact they have on production can reveal root causes—which can include machine downtime, material delays, or absenteeism—that delay a line startup. Calculation: Availability = Time operators are working productively / Time scheduled Example:
In lean manufacturing, machine operator efficiency (MOE) is the performance of an employee who operates industrial machinery. [1] The operator's efficiency is measured as the time spent producing product divided by the time the operator is on duty. [ 2 ]
Modern machine shop workstation, 2009. A machine shop or engineering workshop is a room, building, or company where machining, a form of subtractive manufacturing, is done. In a machine shop, machinists use machine tools and cutting tools to make parts, usually of metal or plastic (but sometimes of other materials such as glass or wood).
Capacity planning is the process of determining the production capacity needed by an organization to meet changing demands for its products. [1] In the context of capacity planning, design capacity is the maximum amount of work that an organization or individual is capable of completing in a given period.
Flow Shop Ordonnancement. Flow-shop scheduling is an optimization problem in computer science and operations research.It is a variant of optimal job scheduling.In a general job-scheduling problem, we are given n jobs J 1, J 2, ..., J n of varying processing times, which need to be scheduled on m machines with varying processing power, while trying to minimize the makespan – the total length ...
The Standard Time is the product of three factors: Observed time: The time measured to complete the task. Performance rating factor: The number pace the person is working at. 90% is working slower than normal, 110% is working faster than normal, 100% is normal.
