GARCIA MELO, JOSÉ ISIDRO; JUNQUEIRA, FABRÍCIO  e  EIGI MIYAGI, PAULO. TOWARDS MODULAR AND COORDINATED MANUFACTURING SYSTEMS ORIENTED TO SERVICES. Dyna rev.fac.nac.minas [online]. 2010, vol.77, n.163, pp.201-210. ISSN 0012-7353.

Nowadays, there is a trend for industry reorganization in geographically dispersed systems, carried out of their activities with autonomy. These systems must maintain coordinated relationship among themselves in order to assure an expected performance of the overall system. Thus, a manufacturing system is proposed, based on "web services" to assure an effective orchestration of services in order to produce final products. In addition, it considers special functions, such as teleoperation and remote monitoring, users' online request, among others. Considering the proposed system as discrete event system (DES), techniques derived from Petri nets (PN), including the Production Flow Schema (PFS), can be used in a PFS/PN approach for modeling. The system is approached in different levels of abstraction: a conceptual model which is obtained by applying the PFS technique and a functional model which is obtained by applying PN. Finally, a particular example of the proposed system is presented.
