The considerable benefits brought up by strategic alliances and diverse types of long term Collaborative Networked Organizations (CNOs) are nowadays widely recognized. There is an increasing demand in the industrial world for concretely implement new forms of collaborations. For example, demand often comes from pre-existent form of clusters or local(More)
Innovative forms of collaborations between companies have been proposed and modelled in literature in recent years. There is an increasing demand in the industrial world for concretely implement this new forms of collaborations. For example, demand often comes from pre-existent form of clusters or consortiums, which want to evolve to more efficient forms of(More)
In this paper an event and object oriented simulator for assembly lines is presented. The tool, developed in Java, is capable to simulate mixed model assembly lines, with stochastic task times, parallel stations, fixed scheduling sequences, and buffers within workstations. The simulator is a flexible supporting tool in finding solution of the mixed model(More)
In the paper, an innovative approach to deal with the Mixed Model Assembly Line Balancing Problem (MALBP) with stochastic task times and parallel workstations is presented. At the current stage of research, advances in solving realistic and complex assembly line balancing problem, as the one analyzed, are often limited by the poor capability to effectively(More)
Alternative energies nowadays have to be more competitive than energy derived from fossil fuels. In this study, the supply chain design problem for a biomass plant is considered. In order to reduce the cost per kWh of energy produced, the whole supply chain involving the biomass plant is modeled. A two-steps methodology, consisting in two sequential(More)
The paper presents one of the most interesting Collaborative Networked Organizations in Italy, namely Gruppo Poligrafico Tiberino (GPT), the first adopting the governance model with the Virtual Development Office (VDO) structure. The network is constituted by 21 companies belonging to the paper converting, packaging and logistics sectors. The nature of the(More)
