Introduction At present, there are a few kinds of polymer materials suitable for pressure sensitive adhesives (PSA) of transdermal drug delivery systems (TDDS), mainly including silicone rubbers, acrylic block copolymers, polyisoprene rubbers et al.
It is even important that SIS-based HMPSAs are solvent-free materials so that they are environmentally friendly with a bright application future [1].

Constraints (4) is constraint before and after the process, that is any order start processing in a production area must have sufficient raw materials can be used which can obtain from pre-inventory, or materials from former process.
Constraints (5) mean that in any moment, when every specification in every area go to produce must have enough materials from former process (include initial inventory).
