Simple questions - what exactly is a Station and a Production Line?
\n\nI'll rephrase it in few points with motivation.
\n\nI'm asking as I don't know very much about this sort of industry, and I'd like to know specifically what is the relationship between a product to multiple/single Station and\\or Production Line.
\n\nAlso, does a Product goes along the Station in each single Production Line?

\n\nOpen questions:
\n\nHi Alessandro,
\n\nIn a Factory, there can be multiple production lines.. In this case, we are seeing (L0, L1, L2, L3) 4 Lines... Each line will doing specific process of production.
\n\nLine will have multiple stations or machine, where specific operations is performed...Like Machining, Turning, Welding..... In this case, L0 line have stations from (0-23), L1 Line have stations 23,24...so and so
\n\nIn each station, set of parameters are measured that can be associated with product quality or production process parameters and machine/environment parameter... usually it will be numeric. Some of parameters are measured with time stamp... Timestamp indicates when measurement during production. Timestamp also give Takt time of production. Also, at station, when specific event happen, the event classified to set of predefined events. Usually it will be categorical feature.
\n\nWhen a particular product is manufactured in factory, an id will be associated that particular product. It will be similar to car vehicle identification number (vin)... There can be multiple product family, however a product will belong one product family.. Based on product family, the product need a set of manufacturing capability... So it will flow to applicable lines and to the applicable stations in the line.. If we trace, path of product that flow through set of stations in the lines, gives the flow path of manufacturing.
\n\nHope it bring some clarity that you are looking for...
\n\nPlease note: It is my first posting in Kaggle... Good to see lot of good interaction.

\n\nYes.. If we assemble all features (Numeric, Categorical, Date) in the order of Features number, for particular ID (Product Serial number or Car VIN), it gives complete history of production history. The record gives, which line, which station, the product Id is passed through production process and measurement are made on product quality, production process parameters... At the end of line, product is evaluated whether it meet all the required product quality , then it is accepted or rejected.
\n\nComing to your questions.\n1. Yes, Product ID ( i prefer to use product that part) , it can move from one line to another line dependent on needed manufacturing capability\n2. Yes.. Product can skip the stations in line.. Suppose particular operations of manufacturing is not needed for type of product (say no painting ), it can skip... When it skips all features associated with station may not be applicable ..
