This book provides for the first time an overview on the current approaches and applications of energy aspects in production and logistics by the use of simulation techniques. During the last decade, the importance of energy in the material flow processes has become more and more important. The pressure to reduce the environmental footprint of prod...

Fulfilment is a key driver for the digitalisation of the grocery sector and thus a major source of value creation. Although value creation is contingent on a multiplicity of contextual factors, extant research has mainly explored fulfilment in the generic realms of e-commerce and does not provide empirically grounded insights into the collective in...

In this contribution, we assess the traditional last mile delivery concept and a framework with commercial parking bays for carriers in terms of their sustainability value for urban stakeholders. We evaluate the potential advantages and disadvantages of commercial parking bays and provide routing solutions based on the given context and stakeholder...

Food price inflation and global geopolitical uncertainties are heightening consumer cost-consciousness and promoting less sustainable consumption behaviours in everyday purchases, particularly in grocery shopping. Hence, online grocery retailers are seeking for strategies to effectively promote ecologically responsible consumption habits while simu...

The advancing digitalization of daily life has led to an increasing number of choices in the digital sphere. User interfaces that require either a judgment or a decision, the so-called digital choice environments (DCEs), are essential focal points for interventions to alter behaviors towards individual or societal welfare. However, there is a lack...

Simulation is a well-known technology for production and logistics, especially for the planning of new systems and the examination of ideas to optimize existing ones. In the past, the main target of such studies has been costs of equipment and personnel, but the continuously stricter view on consumption of energy has shifted this focus towards the...

Transportation is crucial for economic prosperity and the quality of life. Yet, it is also associated with negative externalities (e.g. emissions). Developing and implementing more sustainable means of transportation is one of the major concerns of researchers and policy-makers to improve liveability and contribute to environmental conservation. Th...

Digitization offers several possibilities to alter consumer decisions to support social concerns. The objective of this study is to examine the impact of personalized digital social norm nudges on consumer decisions enriched with the theory of warm glow on e-grocery buying decisions with the aim of supporting social projects. Specific pro-social be...

Boosted by the Covid-19 pandemic, the utilization of online grocery shopping has gained an increasing relevance over recent years. Increasing customer value by reducing friction can be a key option for online grocers to maintain and increase growth, customer loyalty and satisfaction. Being easy and inexpensive to implement, digital nudges can offer...

Environmental sustainability is among the key concerns of our time. Especially the traffic and transportation sector entails a high degree of negative consequences on sustainability metrics such as CO2 emissions, increasing the need for innovative concepts to cope with the requirements of our modern society, while at the same decreasing environment...

This paper presents an approach to develop region-specific simulation models for quantifying and evaluating the traffic-related, environmental, and economic implications of combined passenger and freight transportation via shared autonomous vehicles (SAV). Based on a broad literature review, conceptual peculiarities, interdependencies and character...

With this systematic literature review we investigate the use of graphical tools and standard notations, such as the Business Process Modelling Notation (BPMN) and the Unified Modelling Language (UML), in the development of simulations. In our review, we focus on different simulation methods, such as agent-based simulation, discrete event simulatio...

While simulation modelling has become a popular tool both in IS research as well as organizational practice, the utilization and potential benefits of simulation studies and Digital Twins are still subject to manifold imponderabilities and variables. Hence, this paper proposes a sophisticated applicability framework to provide structural guidance f...

Individuals are increasingly confronted with transactions and decisions in digital environments. This shift in consumption behaviour and context has a high potential to influence operational business processes in various fields such as the grocery retail industry and contribute towards more sustainable operations across different levels. Accordingl...

This study proposes a simulation model for modelling, assessing and quantifying travel distances caused by stationary grocery shopping activities as well as e-grocery deliveries. By means of a sophisticated emission calculation algorithm, the simulated travel values are converted into relevant emission output factors in order to assess the individu...

This study assesses the impact of different strategies for scheduling stock-release timings within a consolidation framework with two different sources in a schematic warehouse, which is investigated in cooperation with "Continental Geschäftsbereich für Antriebskomponenten". The strategies are simulated in line with parameter inputs from the indust...

This chapter examines the impact and role of start-ups on sustainable value creation across global supply chains. Within their highly innovative, disruptive, and often cooperative activities, start-ups can exert a significant influence on the business processes and practices of their supply chain members. Consequently, asymmetric partnerships betwe...

In this article, we present simulation results on the environmental impact of stationary grocery shopping and home delivery in terms of CO2 emissions in four representative city districts in Hanover. Input parameters and comparison variables are based on a comprehensive literature review on grocery shopping behaviour, e-grocery delivery terms and f...

In der Schweizer Logistik werden heute noch viele unterschiedliche und proprietäre IT-Systeme eingesetzt. Daten werden häufig nicht aufgezeichnet oder nur intern genutzt und nicht zugänglich gemacht. Gleichzeitig haben die Kunden das Bedürfnis, mehr Informationen über ihren Auftrag zu erhalten. Die Situation im Detailhandel gestaltet sich anders: D...

With more than 1,400,000 returned questionaires, Self Evaluation In Schools (SEIS) is the largest feedback management project for German schools including more than 5 ,700 institutions. The individual software is a full-hybrid system enabling online, paper and mixed evaluations. It delivers various reports, time series and other products enabling t...

The authors have analyzed more than 700 ERS SAR images of European marginal waters (acquired between December 1996 and November 1998 over the Baltic Sea, the North Sea, and the northwestern Mediterranean Sea) with respect to the detectability of marine oil pollution. By taking into account mean surface winds the authors define the “normalized visib...

A cross analysis of oil spill data obtained by spaceborne and airborne sensors has shown that both systems alone are not capable of detecting all spills occurring. Only a combination of different systems can provide optimal coverage at moderate costs. As the Baltic Sea is overpassed by numerous in-service aircraft every day, the authors suggest to...

Quantities of oil spill data are collected, but usually only general statistics are carried out. The involved authorities often have to deal with statistics as additional work besides their main activities. Therefore, the article contains oil spill statistics as supplementary to official reports. The German spill data for the ten year period 1989 t...
