Abstract
In Europe Health Organizations are progressively modifying their management models to rationalize expenditure in order to assure better levels of effectiveness and efficiency: many countries are going to centralize the management of goods and services supply. In this paper a specific model of centralized purchasing is proposed; it is particularly suitable in cases of severe economy suffering at regional level (e.g. Campania, Lazio, Calabria in Italy) or at national level (e.g. Greece, Ireland, Italy), that means in all those cases where the scale economies, obtainable by supply centralization, would be partly or totally compromised by the extra charges induced by the missing of contractual commitments. This work aims either to analyse such specific approach for centralized purchasing or to propose a simulation model based on Petri net, which could be useful for designing and managing similar case studies.

In this paper a specific model of centralized purchasing is proposed; it is suitable in cases of severe economy suffering at regional level (e.g. Campania, Lazio, Calabria in Italy) or at national level (e.g. Greece, Ireland, Italy), that means in all those cases where the scale economies, obtainable by supply centralization, would be partly or totally compromised by the extra charges induced by the missing of contractual commitments
By using the Woped analysis tool we aim to demonstrate what are the strengths and the weakness characterizing the workflow model designed for Regional Purchasing Agency Public Health Companies” (PHC)
Into the Woped quantitative analysis menu, by setting the parameters of resources’ flow and productivity referred to point 1) to 7), it is possible to evaluate the workflow duration which could be considered as the payment time “p. delay”, that represents one major priority of a Regional Agency that carries out the central role of payment
Summary
One centralized organization (normally a public company) for goods and services procurement, allows significant savings as well as good quality; in these last years, the pharmaceuticals and medical devices purchase processes have been centralized [3] either in several Italian Regions and abroad [4,5]. These centralized procurement bodies, in the most cases, are responsible just for the procurement competition, in order to increase quantities and reduce goods and service costs; the PHC remain normally responsible for the supply chain and especially for the payment to the supplier. This paper analyses the process from the workflow point of view [6] and suggests a specific model, based on Petri Nets, in order to quantitatively outline benefits and critical points
