Production assurance

from Wikipedia, the free encyclopedia

The production assurance referred generally in industrial production, the management, prevention and thus comprehensive measures of emerging faults or deviations between the actual and target values .

Subsection of production control

Production assurance can be understood as a sub-area of production control or production control. Production control includes the following points:

  • The deadline and quantity control, which is designed to meet the specified production order deadline and to produce the specified quantity.
  • The quality assurance which provides all the measures in order to ensure constant product quality.
  • The cost control , which monitors the cause of costs in the areas of personnel costs, operating costs, material costs, among other things.
  • The productivity control , which controls the ratio of the products produced in relation to the necessary resources and services.

The target values ​​that result from the production planning are required for the production . When production is carried out according to plan, the goal is to achieve these target values.

In reality, however, there are always deviations, because the information about the actual actual value is only generated during production. Examples of the deviations between the actual and target value would be that the planned quantity does not match the actual quantity produced or a changed completion date that is postponed due to delays within production.

Possible disruptive factors in production

Faults have an impact through various factors that are due to personnel, disposition or material. Some examples of this:

  • The staff is not present or is not working with the expected performance.
  • The material to be processed or the equipment (tools, machines) are faulty and therefore unusable.
  • The structuring of the work processes is not fixed and planning errors can arise.

Tasks of production assurance

  • Process descriptions in quality assurance describe the documentation of the production processes or manufacturing processes and the associated updates to the methods. For example, the acquisition of modernized systems leads to limited changes in production processes.
  • Maintenance deals with maintenance, inspection, repair and improvement in order to avoid delays in the production process.
  • The staff must be adequately trained and trained in order to avoid possible errors in the planning and implementation of production.

In order to determine the deviations between the actual and target values, controls of the individual production steps are required. If deviations occur, certain measures are taken to safeguard production, which are divided into occurrence-related and cause-related.

Entry-related measures

Entry-related measures relate to current disruptions. These could be changed production orders, such as B. special customer requests, orders to be executed at short notice or failing resources. Here the actual value is adapted to the setpoint.

Measures for production orders received at short notice: Only a minimum quantity or partial quantity of the order is produced in order to deliver to the customer on time. Additional shifts for employees can be added and / or temporary workers can be hired.

Measures for failing equipment: Ready-to-use repair services are requested to repair the failing equipment. These should be available as quickly as possible.

Cause-related measures

Cause-related measures are usually used before an actual malfunction in order to prevent it. The maintenance dates are strategically adjusted depending on the production facility. For this purpose, their interval is adjusted using probability calculations in such a way that a failure of the equipment can be excluded as far as possible. More controls have to be carried out, especially with production processes that are prone to failure. As already mentioned, the employees must be adequately trained so that a smooth production can be carried out. The type and frequency of the training courses are specified by the companies. To ensure that all orders can be completed on time, an extended standard time, including quantity reserves in an interim storage facility, is taken into account and planned. The standard time here is the fulfillment of a production order under normal performance .
