Two resources combine to form an event, i.e.,
　A size(-code) and a (clothing) fabric(-code) combine to form a new event, "(tailor's) cut",
then the combination of them and a color(-code) do another event, "dye".

　　　R(size, fabric) ≡ cut.
　　　F((size, fabric), color) ≡ dye.

　Try new and various combinations of resources, to change the flow of events, i.e.,
　A (clothing) fabric(-code) and a color(-code) combine to form a new event, "dye", then the combination of them and a size(-code) do another event, "(tailor's) cut".

　　　R(fabric, color) ≡ dye.
　　　F((fabric, color), size) ≡ cut.

　As described above, a new combination of the resources can change an order of events, and moreover, it can create a new event, i.e.,
　If we try to reduce inventory by launching a sales promotion at convenience stores,
　as the inventory is a combination (compounded concept) among storehouse(-code), shelf(-number) and (marketable) product(-code), you can get a new event, strategic "display (on exhibit)" management, with a new combination of the resources--shelves and products--on the side of the daily stocktaking--which products should be on which shelf to get customers' attention: in this country, convenience stores are small-sized, and they can get a high turnover of products in limited space of shops through the change of product-alignment on shelves at daytime and at night.
　The strategic "display" management is, marketingwise, called "ISM (In Store Merchandising)" that can arouse customer interest.

　　　R(shelf, product) ≡ display.
　　　F((storehouse, shelf), product) ≡ inventory.
