The accumulation of empty cargo containers in urban areas is an important issue for communities and policy makers as these containers seem to restrict the use of valuable land and diminish the quality of life of communities close to ports and storage depots. Different reasons have been offered...

In bioenergy villages, local bioenergy plants are installed to supply electricity, which is fed into the national grid, and to heat households through a local heat distribution network. In this paper, a linear mathematical model, which economically optimizes local bioenergy production and...

The introduction of GNSS as primary mean of aircraft navigation calls for a rationalization of existing ground-based assistance networks. Several studies indicate the DME as the possible back-up solution, and therefore the only radio assistance to be maintained. The paper proposes an algorithm...

Transportation Problem (TP) is one of the basic operational research problems, which plays an important role in many practical applications. In this paper, a bio-inspired mathematical model is proposed to handle the Linear Transportation Problem (LTP) in directed networks by modifying the...

We consider a two-stage defender-attacker game that takes place on a network, in which the attacker seeks to take control over (or “influence”) as many nodes as possible. The defender acts first in this game by protecting a subset of nodes that cannot be influenced by the attacker. With full...

We propose a framework for designing the supply chain network for biomass co-firing in coal-fired power plants. This framework is inspired by existing practices with products with similar physical characteristics to biomass. We present a hub-and-spoke supply chain network design model for...
