Agent-Based Modeling of Deshopping Behaviour: A Single Shop Model with Multiple Deshoppers

Deshopping is rapidly turning into a modern day scourge for the retailers worldwide due to its prevalence and regularity. The presence of flexible return policies have made retail return management a real challenging issue for both the present and the future. In this study, we propose and develop a multi-agent simulation model for deshopper behavior in a single shop context. The background, theoretical underpinning, logical and computational model, experiment design and simulation results are reported and discussed in the paper.

Increase urban freight efficiency with delivery and servicing plan

Delivery and Servicing Plan (DSP) is an innovative logistics concept for more efficient organisation of deliveries from the point of view of the receiver of the goods. DSP actions tested in this study include reducing the number of suppliers, grouping deliveries, selecting less distant suppliers and others. It is shown that DSP can help reduce externalities and lead to a substantial reduction of costs. A new tool was developed to calculate the benefits of different DSP options for businesses and the public sector. Reductions in costs and externalities exceeding 50% have been demonstrated in a few cases. Remaining difficulties with the concept are organisational issues, lack of knowledge, need to give external advisory support for shop owners and the limited number of successful applications to date.

Drink availability is associated with enhanced examination performance in adults

While dehydration has negative effects on memory and attention, few studies have investigated whether drinking water can enhance cognitive performance, and none have addressed this in a real-world setting. In this study we explored the potential benefits of the availability of water for undergraduates. The exam performance of students who brought drinks in to exams was compared with those that did not for three cohorts of undergraduates (N = 447). We employed earlier coursework marks as a measure of underlying ability. Students who brought water to the exam achieved better grades than students who did not. When coursework marks were covaried, this effect remained statistically significant, suggesting that this finding was not simply due to more able students being more likely to bring in water. This implies that water consumption may facilitate performance in real-world settings, and, therefore, have specific implications for the assessment of undergraduate learners under examination conditions, but further research is required to evaluate this hypothesis.
