Renewable energy production plays a crucial role in the energy transition. However, many renewable energy sources (RES) are intermittent, and there is often a mismatch between energy production and consumption, which can be partially solved by storage. In this paper, we investigate the...

We propose inventory replenishment and lateral transshipment policies for a distribution network. The distribution centers place weekly regular orders and daily urgent orders to the factory. Two classes of stochastic demands, pre-ordered and peddling, cause either backlogging or lost sales when...

This study investigates the capacity of a developed production planning model to coordinate energy management within a hybrid energy system. The specific focus is on energy-intensive manufacturing firms utilizing renewable energy generation and energy storage. Unlike prior research in the field...

In 2020, humans were responsible for emitting around 50 GtCO2e (about 6.4 tonnes per person). Under the Paris Agreement, national governments have agreed to rein in these emissions to almost zero within 30 years. In order to accomplish this, greenhouse gas (GHG) emissions inventories are needed...
