Furthermore, in the method according to the invention, an effect of the variation on a financial value of the end product is evaluated.
- the assessment possibly incorporating other aspects such as the resulting quality of the final product and / or the duration of the production, will lead to a decision as to whether or not the variation will be incorporated into the production process.
- an operator may intervene to specify the variation and / or to make the assessment. Trying out different scenarios leads to a deeper understanding of the production process, which can therefore be optimized.
- the method may proceed automatically without the intervention of an operator.
- the production process is mapped in a mathematical model containing a set of parameters with at least one parameter as an element.
- At least one variation parameter from the parameter set relating to the at least one starting material, an intermediate product, the end product and / or the production process but not to machines used in the production process is varied by one variation in the model.

- FIG. 1 shows a flowchart with the method according to the invention.
- FIG. 2 shows an embodiment of a user interface as shown in FIG.
- FIG. 1 shows in a flow chart the basic idea of the method according to the invention.
- the starting point is a textile operation in which a textile production process 101 is carried out. This is, for example, a spinning mill that produces a yarn as a final product from raw cotton delivered in bales as a starting material. Intermediate processes in this production process 101, that of different
- Work stations are running, z. For example: opening, cleaning, mixing, carding, doubling, combing, drawing, spinning and / or winding.
- Each of these intermediate processes may be characterized by various parameters relating to the starting product, an intermediate product, the end product, the workstations, and / or environmental conditions during the production process 101 can. These parameters or a subset thereof ultimately characterize the entire production process 101.
- a mathematical model 102 of the production process 101 is set up, which contains parameters of the production process 101.
- the model 102 provides a
- M M (x i , ..., x n ), where ⁇ x i , x n ⁇ is an amount of the parameters entering the model 102, and n is a natural number indicating the number of parameters considered.
- Production amount M preferably refers to the final product. You can z. B. refer to a unit of time or to a certain amount of the final product.
- At least one variation parameter Xj which is to be varied, is calculated from the
- Parameter set ⁇ xi, x n ⁇ is selected 103, where 1 ⁇ i ⁇ n. It is to such a parameter related to the starting material, an intermediate, the final product and / or the production process 101, but not in the production process 101 used machines relates.
- the variation parameter Xj should also be able to be varied within certain limits in the real production process 101.
- the selection 103 of the variation parameter Xj can be done manually by an operator or automatically in a computer.
- the values of the parameters x l5 x "are set 104 are preferably those values that are currently set in the production process 101 to be optimized. Also, a price p per quantity M of the final product to which the production quantity M refers is input 105. A financial value P - or a total price which can be obtained with the production quantity M (per unit time, per quantity of the starting product, etc.) -, is accordingly.
- the value difference ⁇ can be positive, negative or zero.
- a positive value difference ( ⁇ > 0) means that with an assumption of the variation ⁇ ; a higher price could be achieved in the production process 101 than with the original variation parameter Xj and vice versa.
- the value difference ⁇ goes into a valuation 108 of the variation ⁇ ; one. It may, but need not be, the only quantity considered in Rating 108. Other variables that can be included in the rating 108, z. B. a quality of
- the quality can be estimated from experience or numerically quantified by one or more quality indicators become.
- the score 108 may be made by an operator or automatically by a computer.
- the production process 101 is optimized. Otherwise, one or more of the inputs 103-106 described above are changed, e.g. B. a new variation parameter Xj and / or a new variation Axj chosen, and thus calculates again the value difference ⁇ 107.
- the acquisition 109 can be done manually by an operator or automatically. In the latter case, one can arrive at a controlled textile production process 101 in which the variation parameter Xj is the controlled variable.
- Figure 2 shows an example of a user interface 2, as they are for the inventive method on an electronic display unit, for.
- a computer screen can be provided.
- the embodiment relates to the influence of cutting numbers when winding yarn.
- the user interface 2 contains fields for input and output as well as, optionally, further information.
- the inputs can via an electronic input unit, eg. As a computer mouse or a keyboard can be made.
- the display unit and the input unit can be combined in a touch screen. Especially clear, simple and therefore advantageous is the user interface 2 on a single
- input fields 21 1-215 for inputs 104 (see FIG. 1) of five parameter values x l5 ..., X5 are located in an upper part 21 of the user interface.
- the inputs 104 are made by means of sliders or numerical entries in input boxes, which are located at the top left.
- the five parameters are the following:
- the variation parameters are provided below the input fields 221, 222 for the original parameter values x 6 , x 7 input fields 223, 224 for new or desired values ⁇ 6 ', x 7 '.
- These inputs 104 can be made by incremental buttons or by numeric entries in corresponding input boxes.
- an input field 241 for the input 105 of a price p per coiled yarn amount which in the exemplary embodiment of FIG. 2 amounts to $ 2.5 / kg.
- the price entry 105 can be made in the same way as the entries 104 of the two further parameters x 8 , X9. It goes without saying that the inputs of the parameter values xi,..., X9 can be made in other ways known per se than those described above by way of example.
- the total number of parameters n may differ from the example value 9.
- the embodiment of Figure 2 can be saved with the input reduction of the cutting numbers $ 9 736 per year.
- 2 further outputs can be provided in the lower left part of the user interface.
- this is a bar graph 260 for various efficiency losses expressed as a percentage.
- a first pillar 261 indicates efficiency losses due to dyno changes, eg 11%, a second pillar 262 efficiency losses due to the original cut numbers, eg 11%, and a third pillar 263 efficiency losses due to the new cut numbers, eg 9%.
- the calculated value difference ⁇ results from the increase in efficiency, as can be seen from the comparison between the second 262 and the third 263 column.
- the desired reduction of the cutting numbers can also change the quality of the yarn produced.
- the reduction in quality may also result in a reduction of the achievable price p per kilogram of yarn. This could be taken into account in the model 102 by providing on the user interface 2 another (not shown) input field for the new price p 'per kilogram.
- a table or a function are stored in a memory of the executing computer, which assigns each yarn quality (or each set number of cuts) the corresponding price p 'per kilogram.
- Variationsparameters X the choice of the parameter values x l5 ..., x n and / or the choice 106 of the variation ⁇ ; made so that the quality of the final product remains approximately the same or at least not significantly reduced.
- the method according to the invention is carried out in a region in which the variation ⁇ ; a small change AQ »0 of the quality, but causes the largest possible change ⁇ » 0 of the financial value.
- a computer can find such areas particularly well.
- the variation Axj does not affect the price p per set.
- User interface 2 are displayed in graphical and / or numerical form.
- the choice 103 of the at least one variation parameter x; can be done by selecting the appropriate user interface 2.
- a single user interface 2 can be provided, on which the at least one variation parameter x, is selected.
