It is unquestionable that in all areas of life few things are no longer subject to quantification, comparison or measurement.
Any plan is subject to schedules, to a contrast with the figures of the previous period or to the achievement of a predetermined objective. In short, a measure is used.
In the industrial field, the TIME factor acquires a first-order dimension.
Subject to the time factor, and BASED ON ITS MEASURE, the techniques and aspects that are applied in the Productive Sphere are developed and their common objective is to optimize the resources available in order to achieve the highest possible level of PRODUCTIVITY.
As a deduction from the previous paragraph, we can define PRODUCTIVITY as the relationship that exists between production and the resources applied to obtain it.
The Measurement of Time, with being one of the specific techniques to achieve improved productivity, is also present in many other
The purpose of the measurement of the elaboration times of the tasks is to define a standard time that can serve as the basis of use for any provisional analysis.
Therefore, when we refer to "Processing Times", we are referring to previously normalized or standardized times, that is; that any operation carried out under a specific working method will have a Normal or Standard time that will always be the same, as long as the working conditions, method, characteristics of the materials or machines, tools, etc. do not vary.
Said time will be referred to a normal action, defining it as that which the average operator can carry out at a normal pace during a working day.
- The most primitive procedure is based on pure appreciation. Obviously, the determination of times by estimation is only used in very specific cases. It is not very exact and presents functional problems, although sometimes it is essential due to the impossibility or serious difficulty of using another method. However, the estimate improves when it is based on a database of timing of similar operations or of times invested in comparable operations. Its use can be effective in the application of an incentive system for non-repetitive work, accompanied by a performance regulation mechanism.
• Timing films:
- It is the most used in the industrial world and which we will deal with in the following sections
• Tables of normalized data:
- This procedure is based on Timing. Its function is to determine times for tasks or non-timed jobs, according to the relationship between the times and the reason for their variation in known data
• Default times:
- The technique is based on the use of standardized time tables for micro movements. Like any system, it has advantages and disadvantages, and its use is advisable in companies where there is a great definition of the working method, operations in which the conditions of variation of the working conditions are practically nil, ...
- It is a time allocation system based on the exhaustive analysis of the operative method that is broken down into pre-established elements (turn, reach, raise, position ...)
- Each of these elements has a pre-established standard time, which is normally measured in TMUs, (ten thousandths of an hour at normal activity including the rest coefficient)
- It is useful for short, repetitive and highly standardized operations
- Requires very expert analysts
- You can ignore elements of random variation that are not taken into account in the measurement
- The historical average time is assigned to an operation according to existing data records. Its reliability depends on that of the records. It is known what has taken, not what should take (neither the method nor the performance is questioned)
