Abstracting each path in the step 1.2 into a path model according to Dijkstra algorithm;
according to the path model, the following algorithm model is abstracted:
d [ feature, (S1, S2, … … S18) ] represents an optimal route of vehicles of different vehicle types and colors from the painting process path S1 to S18, and feature represents combination information of vehicle type colors;
t { feature, (S1, S2, … … S18) } represents the minimum process integration time of vehicles of different vehicle types and colors from the painting process paths S1 to S18;
t (feature, si) represents the length of time that vehicles of different vehicle types and colors pass through the Si segment coating process path, i=1, 2,3 … …;
carrying out double-color vehicle prediction algorithm modeling on historical data (the historical data comprises vehicle body information, vehicle running information and time information of the vehicle passing through an original path) of a previous double-color vehicle running in a workshop by using a big data processing flow and through data cleaning, feature extraction and data modeling links; the method comprises the steps of designing a feature extraction module according to process knowledge, extracting key process features, and respectively modeling each key process point, so as to realize a vehicle demand sequence prediction model of the full-flow double-color vehicle; the method comprises the following steps: data cleaning: according to the history data of the last year, removing special offline data, data which do not completely pass through all paths 1 or paths 2 and data which cannot be identified in vehicle type and color according to vehicle material codes in the history data; feature extraction: extracting three characteristic information of vehicle type, color and time length passing through each path from the cleaned data;
data analysis: for historical data, all observations were recorded: vehicle model, color and duration (duration of each painting process path), statistical historical data distribution;
for the extracted characteristic information, the duration T of the bicolor vehicle passing through all process paths is calculated as follows: t (feature, tech) =t (feature, tech (S1)) +t (feature, tech (S2)) + … +t (feature, tech (S18))
Wherein T represents the total duration of the two-color vehicle through all process paths; the Feature is a bicolor vehicle with different vehicle types and different color characteristics; tech is the cumulative length of all coating process paths experienced in the middle of the two-color vehicles S1 to S18; t (frame, tech (Si)) represents the painting process time of the bicolor vehicle with different vehicle types and different color characteristics on the Si path;
because the number of the corresponding stations in the process route is a fixed value, the corresponding standard process is time-consuming as shown in fig. 2 by combining the above-mentioned historical data analysis under the condition of not considering shutdown and shutdown after finishing: path 1 is finally calculated, which takes 1770 seconds, path 2 takes 1530 seconds, and path 3 takes 930 seconds;
when a vehicle enters a painting workshop and enters an S1, after the vehicle body pretreatment path, the vehicle is identified to be a double-color vehicle through RFID (Radio Frequency Identification, radio frequency identification technology), a path with the shortest duration is searched through a double-color vehicle bifurcation path management method so as to meet the train requirement of the double-color vehicle for coating.
