Job planning (also briefly AV called) are all preparing measures for the economic manufacturing of products. One can divide these tasks in principle in work planning and into job control. Among the work planning all uniquely arising planning measures rank to the Sicherstellung of the economic production of the products. The job control is responsible for all measures, which are necessary for one the work planning corresponding job execution.
To the uniquely arising planning measures on a long-term basis the planning of the entire manufacturing and mounting system of an enterprise is to be called. These technical organizational-economical task often also factory planning one names.
To the short term tasks the structure of working documents for the production of products belongs to the work planning. For this count the production of manufacturing parts lists and schedules. Latter activity consists of the planning of the jobs as well as above all the Vorgabezeitermittlung. Also the conception of suitable tooling (devices, tools, measuring instrument, etc.) takes place in this connection frequently. One counts the programming of manufacturing equipment, which is equipped with a CNC control, likewise to the uniquely arising short term tasks of the work planning. Also the calculation of the product costs developing on the schedules ranks among the tasks of the work planning.
Among the substantial major tasks of the work price increase one ranks:
- Material disposition, - date and capacity planning as well as workshop control.
Basis for order execution are the operational sequences and standard times specified by the work planning in the schedules. Further important data are the capacities of coworkers, machines and operational funds, in the current situation the available, i.e. the number of available working hours in the future periods.
Materials requirements result from the manufacturing parts lists as well as from the production program. The material disposition presupposes an exact overview of the available stocks, first over the current stock at the time of planning, then in addition, over the future at the time of order execution available existence. This requirement planning the so-called order bill follows.
For the components manufactured in self-manufacturing now in the context of the scheduling first the unity expensive dates and the completion dates of all product components are determined. This happens with the help of a so-called run time limitation. The following capacity planning gives itself an overview of from the available production orders the capacity load for all capacity units, resulting in. Since frequently when first planning planning no balanced capacity load results, i.e. periods to small extent of utilization are also replaced e.g. from periods also to high extent of utilization, must be arranged before order release a capacity alignment and if necessary a according to schedule shifting of the production orders. For this very computer-bound task today often PPS systems (EDP software systems for production planning and - control) are used.
As next main function of the job control the workshop control is to be seen. To it the punctual order start with the expression of the necessary order accompanying documents, like route cards, e.g. belongs material requisitions slip and works orders. These documents go to the distribution into the different workshops and cost centres of the enterprise. The second task of the workshop control is the regular monitoring of the working progress on the basis the feedbacks of the enterprise.
A multiplicity of different designations is usual for the range of the job planning in literature and in the enterprises; often for this the term preparation is selected; similarly instead of work planning and job control frequently also the designations production planning and progressing are used. With job planning often also the place or department is called, whose field of application is the job planning.
The temporal range of the tasks specified above can be very different depending upon enterprises and/or production method and type of manufacturing. In enterprises of the single and small-batch manufacturing the range of arbeitsplanerischer activities (operational sequence planning, standard time calculation etc.) is multiple prevailing. During quantity production often is the job control determining. Into enterprises with mass production mostly specific machinery are used for production. Here the focal task lies in development, structure and constant optimization of tooling, i.e. within the range factory planning. The production of variant-rich products in series, and/or mass production (e.g. automobile industry) is beyond that mostly connected with large expenditure for the material disposition.
