Definitions
- the invention relates to an industrial production method and to a production apparatus for producing a production item of any kind.
- the item to be produced may be a consumable item of daily life as well as an industrially manufactured item of food.
- load curve over time describes not only the time course of the energy required for production but more generally the time course of the amount of resources required for production, including energy.
- Resources may be e.g. Consumables such as manufacturing components, ingredients or small parts such as screws or nuts. But resources are also the technical gases required for production.
- the load history of a production process is essentially determined by the production plan and environmental conditions.
- the production plan describes at which time which quantity of the production goods is to be produced and thus contains planned production parameters.
- Environmental conditions include such parameters as outside or inside temperature, air pressure, humidity, precipitation or sunlight. Such environmental or environmental parameters have an influence on the production process and must therefore be taken into account for the implementation of the production plan. In order to be able to provide the energy or the resources required for the production process in a timely and cost-effective manner, it is therefore necessary to ensure that it is safe Predicting the temporal load curve, both planned production parameters and expected environmental parameters are taken into account.
- the object of the invention is to provide an industrial production method, wherein for the provision of the required equipment and / or energy, a temporal load profile is predicted with the simplest possible means in a manageable and interpretable way manageable. It is a further object of the invention to specify a corresponding production device for carrying out the production method.
- the first object is achieved according to the invention by an industrial production method, wherein for the provision of the required operating resources and / or energy, a temporal load profile is predicted automatically starting from expected ambient and planned production parameters by the following steps:
- the invention is based on the consideration that a model-based prediction method generates forecasts for the user in an incomprehensible way ⁇ via internal, not easily understandable, links of clearly arranged databases. This is the case, for example, if the prognosis of the temporal load curve is created by means of a neural network.
- the underlying databases which include a model of the production process, and the changing links between the individual database elements are neither accessible to the user nor understandable. Since the forecasting process is based on a model of the production process, both its maintenance and its adaptation to changed production conditions require a great deal of effort.
- the invention proceeds from the consideration that, taking into account existing parameter sets (po, pi, ...
- p n tion parameters from ambient and planned production, which over a number of rules (Ro, Ri , ... R n ) are each assigned a number of known or measured load history lines ((y (t) o, y (t) i, ..., y (t) n ), a prediction of the time load curve for an expected one Parameter set z can be determined by appropriate interpolation within the space, which is conceptually spanned by the known parameter sets (po / Pi, ⁇ • -Pn.)
- a load curve describes the course of the load over time and is used here for a known load curve in contrast to the load profile of the parameter set z to be predicted.
- an expected parameter set z which is defined by planned production parameters and by expected environmental parameters, is related to parameter sets (po, pi, ... P n ) / with respect to which already rules (Ro, Ri, ... Rn) for assigning a temporal load profile
- the weights ⁇ i of the known load profile lines can then be determined and interpolated correspondingly weighted linearly with respect to the predicted time load profile of the parameter set z.
- the number of known parameter sets (po, Pi,... P n ) used for interpolation is limited to one with respect to the number N of the parameters an increased number, so that the paraxial set z in the N-dimensional space of the parameters can be enclosed by these N + 1 parameter sets .
- the parameter set for the nearest N + l known parameter sets (po / Pi, • • P N) are then taken into account for the linear interpolation of the prediction of the temporal course load.
- the invention offers the advantage that after selecting the relevant known parameter sets (po, Pi, ... p n ) only a small Parametris réellesaufwand during commissioning is necessary. In particular, the production process does not need to be modeled.
- the underlying knowledge base of known parameter sets (po, Pi, • • -Pn) as well as the rules (Ro, Ri, ... R n ) for the assignment of load curves (yo (t), Yi (t) ... y n (t)) contains only measured curves and parameter sets from the user's planning. Unlike weight parameters when using neural networks, all these data are familiar and interpretable to the user.
- i + 1 is greater than the number of total existing parameter sets, it is impossible to select N + l from the existing parameter sets so that they enclose the parameter set z, eg because z is outside of all previous parameter sets. In this case, for example, is determined by expert information or by measurement of z associated load history and included in the rule base. A forecast is not possible. If i + 1 is less than the total number of existing parameter sets, then in the set of N + 1 selected parameter sets at location j of [0 .. N] the parameter set pi is replaced by the parameter set pi + i. If j is greater than zero, then the first j parameter sets selected are replaced by the parameter sets (p ⁇ , ... pj-1). The thus modified selection of N + 1 parameter sets is returned to step 3.
- This exemplary method of selecting N + 1 parameter sets as the basis for the linear interpolation ensures that the N-dimensional space spanned by the selected parameter sets is minimal and thus the accuracy of the interpolation is maximal.
- the found weights ⁇ i are used for the linear interpolation.
- the distances of the parameter sets (Po, pi, ... p n ) to the expected parameter set z are determined by calculating the Euclidean distance in the N-dimensional space of the parameters.
- the method is performed self-learning, the self-learning is done by a measured actual load curve y M (t) for a parameter set z given as a learning rule, the predicted load history y (t) determined for the same parameter set z , the predicted load curve y (t) is compared with the measured load curve y t i (t), and the learning rule for the parameter set z is adopted when a defined similarity is undershot.
- the second-mentioned object is achieved by a production device according to the invention in that a prognosis module is designed for determining and output of a predicted according to one of the preceding claims load profile.
- the forecasting module can be, for example, a control unit, a computer or a microchip.
- the forecasting module is networked with a production planning system and a consumption measuring point.
- rules Ro, Ri, ... R n
- parameter sets po, pi, ... p n
- FIG. 3 shows in a two-dimensional parameter space the determination of edge vectors k
- FIG. 3 in a three-dimensional space the assignment of rules R and the load value y (t) at a specific point in time t to the known parameter sets p
- FIG. 4 shows schematically the linear interpolation of known load curves y n (t) for forecasting the time load curve y (t) and
- FIG. 5 schematically shows a production device with a prognosis module for determining the temporal load curve.
- a two-dimensional parameter space is represented graphically by a coordinate system in order to illustrate the production method.
- an environmental parameter 2 such as the outside temperature
- a production parameter 4 such as the amount to be produced
- five known parameter sets po to p 4 are shown in the coordinate system.
- Each of these parameter sets is clearly an environment Parameter 2 and a production parameter 4 assigned.
- the load curve specifies the time course over which the required energy must be supplied to the production process.
- an expected parameter set z is entered into the coordinate system according to FIG. 1 for which a prognosis for the temporal load profile is to be output.
- the expected parameter set z contains from the production plan the planned quantity of the production item as well as the prediction of an environmental parameter 2 to be expected at the time of production.
- the search for rules relevant for the given parameter set z for outputting a prognosis of the temporal load curve is regarded as the search for the minimum number of already known, parameterized sets of rules in N-dimensional space which form a body enclosing the parameter set Z. It can be seen that the minimum number of parameter sets forming such a body in an N-dimensional vector space is always equal to N + 1.
- the expected parameter set z lies between the known parameter sets p 0 to P 2 - which surround it.
- the body envelope 5 is shown.
- the known parameter sets p 0 to P 2 from the total of five parameter sets are the three closest parameter sets.
- the parameter sets p0 to P2 in the N-dimensional space of the parameters are the N + 1 parameter sets which satisfy the condition nearest and enclosing.
- the Euclidean distance is used for distance consideration.
- a weight must now be determined, after the known load curves are superimposed.
- the constellation is taken from the known parameter sets po to ⁇ n provided with rules and the expected parameter set z as a design problem, in which the parameter set z must be constructed from a start parameter set that is defined by a start rule is given, and from a vectorial description of the enveloping body.
- the solution to such a design problem provides N weights for the associated rules. This is illustrated by FIG.
- FIG. 2 again shows the two-dimensional parameter space according to FIG. One recognizes the environmental parameter 2 plotted on the X-axis and the production parameter 4 plotted along the Y-axis.
- N + 1 parameter sets P 0 to P 2 are shown , which were closest to the parameter set Z according to FIG Enclose body.
- the parameter set Po closest to the parameter set z is used as the starting point.
- the weights ⁇ i are
- the two edge vectors ki and] z 2 can now be seen in the two-dimensional parameter space.
- the edge vector ki connects the parameter set po with the parameter set pi.
- the second edge vector k 2 connects the parameter set Pi to the parameter set p 2 -
- the parameter set z can now be described as ⁇ i * ki + ⁇ 2 -k2.
- the assignment of the load curves y n (t) to the parameter sets P n is apparent from FIG.
- the load curves y n (t) assigned to the parameter sets p n are shown schematically in a third dimension, for example by a load value at a specific time t.
- the rule Ro assigns a known load gangway yo (t) to the parameter set po.
- the parameter set P 2 to which the corresponding load curve y 2 (t) is assigned via the rule R 2 .
- the problem now is to determine from the found weights ⁇ i the load profile associated with the parameter set z as a prognosis of the temporal load profile. This is shown in more detail in FIG.
- the prediction of the time load curve for the parameter set z is now determined by means of linear interpolation.
- the load-flow lines yo (t), yi (t) and y 2 (t) are shown schematically in FIG. 4 as the first, second or third load profile line 10, 11 and 12, respectively. While the first load curve 10 shows a positive triangular course, the load curve 11 includes a more rectangular course. The third load profile line 12 in turn shows a straight course with a triangular valley at the end.
- the linear interpolation of the temporal load curve on the parameter set z is now decomposed into an interpolation along the first edge vector ki and into a second interpolation along the edge vector k2.
- a linear interpolation between the first load course line 10 according to yo (t) and the second load course line 11 corresponding to yi (t) is created by means of the first weight ⁇ i.
- the weight ⁇ i can be understood in a sense as a path in the direction of the parameter set pi.
- the time duration changes linearly from the duration d 0 of the first load curve 10 towards the duration di of the second load line 11. Accordingly, the time duration of the first interpolation of a load curve 16 lies in the distance between the plotted by ⁇ i Lines 14, each connecting the starting point and end point of the first and second load profile line 10 and 11, respectively.
- the course of the curve is linearly interpolated, so that the triangular rise of the first load profile line 10 flattens as the approaching second load profile line 11 approaches, whereas subsequently more and more the rectangle of the second load profile line 11 grows out.
- the first interpolation of a load curve 16 with a linearly interpolated time duration and a linearly interpolated curve shape results pictorially.
- the weight ⁇ 2 is taken into account, which describes the proportion of the third load curve 12 on the forecast of the temporal load history. Taking into account the time duration d 2 of the third load curve 12 corresponding to Y 2 (t) and its time course, the prediction of the time load curve 17 with the drawn time duration d is finally produced by a corresponding linear interpolation.
- the temporal load curve includes a total of elements of all three load curves 10,11 or 12, which were weighted differently in the calculation.
- the predicted time load curve y (t) is generated from the load curves ⁇ ⁇ o , y ⁇ r .., y n ) of the rules (Ro, Ri ... R n ) such that for each time point
- the similarity measure considers the difference between the two curve durations and the similarity of the curve within the common duration.
- the similarity measure is defined by the following calculation rule: a.
- d min (d p , d M ).
- t k k-.
- the curves are usually obtained by sampled individual measurements, and the grid results from the measuring device.
- Two sampling points y M (t k ) and y P (t k ) are considered equal within a given tolerance ⁇ , if:
- Threshold eg 5%
- the offered learning data set is additionally included in the knowledge base. Otherwise, no further learning takes place.
- the method or the underlying system ceases to be learned when an area of the parameter space is detected sufficiently tightly by measurements. Then a prognosis of the temporal load curve will not deviate sufficiently from a measured load curve. The system determines reliable forecasts.
- FIG. 5 schematically shows a production device 20 for carrying out a production method.
- the production equipment 20 comprises a central unit 22 for controlling the production process.
- the production method is shown schematically by a production line 24 and a heat bath 25.
- the central unit 22 comprises a first control unit 27 and a second control unit 28, respectively.
- the central unit 22 further comprises a prognosis module 30 which, via a connected display unit 32, outputs to the user for the timely procurement of energy or consumables such as consumables a prognosis for the time course of the production process.
- the prognosis module 30 is connected via a first connection line 34 to a production planning system 36, via which it automatically retrieves parameter sets 37 which comprise planned production parameters and expected environmental parameters.
- the prognosis module 30 is connected via a second connecting line 39 to a measuring point 40, via which it can call up measured load curves for the purpose of self-learning and for the purpose of comparison with self-generated forecasts.
- the evaluation module From the parameter sets 37, the evaluation module according to the method described creates a prognosis for the temporal load history of the production method.
- the evaluation module 30 is capable of self-learning to improve its own knowledge base in order to make increasingly reliable forecasts.
