UK climate change policy has long been concerned with the transition to a more sustainable energy mix. The degree of competition in electricity markets rises as these markets become more and more liberalized. In order to survive in such an increasingly competitive setting, electricity producers...

In this paper we develop a mathematical model to study optimal replenishment policy for an economic order quantity system considering items with deterioration. Demand is time dependent and follows a power pattern. The system operates over an infinite planning horizon. Replenishment is...

MFCs (microbial fuel cells) are a promising sustainable technology to meet increasing energy needs, especially using wastewaters as substrates, since they can generate electricity and accomplish wastewater treatment simultaneously. The MFC is a complex system involving bio-electrochemical...

The paper highlights the problem of mathematical modeling of a complex manufacturing system which is a potential synthetic representation of a real production environment. Production lines are parallel. Each production line consists of work stations which are placed serially along the...

The development of two analytical models that describe the thermal behaviour of solar air heaters of double-parallel flow and double-pass counter flow is presented. Based on the local energy balances, algebraic expressions for the efficiency factor F′ and the overall heat loss coefficient, UL,...

Purpose – Currently, the majority of designed robots are not well‐matched to their applications because designers do not employ a clear and organized design process. Additionally, the high cost of robotic systems makes it difficult to financially justify the use of this technology. The...

The paper presents the formulation of a mathematical model using the expected path approach in order to minimise the expected long-run total system cost per cycle of a two-retailer inventory system with preventive lateral transshipment. Each retailer employs base stock periodic review policy....
