Circular economy implementation in railway systems beyond net zero

Waste and circular economy

Landfills And The Circular Economy

Promotion of resource efficiency and development towards a circular economy is widely supported. Many products and materials that are brought into the economy contain hazardous substances. These substances may be acceptable during the consumption stage, but due to accumulation in the environment may also cause impact to human health and the environment after consumption.

It is widely considered that by implementing ICT (Information and Communication Technologies)-enhanced networks, economic performance will further increase. However, when it is established that work can be done more efficiently—shouldn’t that also allow people to work less? The article addresses a new vision of developments concerning work relations, work organisation and the distribution of wo...

Simplification of a Petri Net controller in industrial systems

This paper deals with the problem of forbidden states in discrete event systems modeled by Petri Net. To avoid the forbidden states, some constraints which are called Generalized Mutual Exclusion Constraints can be assigned to them. Enforcing these constraints on the system can be performed using control places. However, when the number of these constraints is large, a large number of control p...
