Process improvements resulting after Spaghetti model implementation in the manufacturing sector have resulted in a decrease of 30 to 35% overhead cost. Also, as much as 85% set-up time has been reduced.
Spaghetti models used in drug discovery and drug product development research speed-up phases 1,2 and 3 of new product development pathway. They also play a pivotal role in identifying drug interactions. Identification of differences in plasma-half lives of drugs in different population groups in a clinical trial can effectively be done using Spaghetti models.
