This paper presents multiple readings to solve a vehicle routing problem with pickup and delivery (VRPPD) based on a real-life case study. Compared to theoretical problems, real-life ones are more difficult to address due to their richness and complexity. To handle multiple points of view in modeling our problem, we developed three different Mixed Integer Linear Programming (MILP) models, where each model covers particular constraints. The suggested models are designed for a mega poultry company in Tunisia, called CHAHIA. Our mission was to develop a prototype for CHAHIA that helps decision-makers find the best path for simultaneously delivering the company’s products and collecting the empty boxes. Based on data provided by CHAHIA, we conducted computational experiments, which have shown interesting and promising results.

Improving the quality of digital health care through information and communication technology can mainly contribute to the clinical, social, financial, and economic systems’ success, especially during the COVID-19 pandemic period. The co-design approach, which unleashes the end-user power, can contribute actively in improving the healthcare systems. It deals with understanding the user behaviors, requirements, and motivations through observation, inspection, task analysis, and feedback techniques. Consequently, both the co-design and digital technologies might empower the management of patients’ health and that of their families. The research strategy is based on a systematic literature review and meta-analysis to summarize how the co-design methodologies handled the existing technology-based health systems for their improvement. Based on the findings, we establish the following hypotheses: (i) A user-centered methodology for service implementation might offer a promising tool to enhance the healthcare services quality before they be launched; (ii) Several limitations can affect the co-design approach in digital health, such as a bias for a patients’ group. Efforts have been made to reduce this risk by identifying bias at an early stage, or different groups should be included in the test phase for example; (iii) Use decision-making devices that handle technologies for patient and clinical healthcare solution

This study aims to investigate the factors that perceive citizens’ intention to adopt smart city technologies in the Arab world. A self-administered questionnaire that included 312 end users as citizens in Amman, Jordan’s capital city, was used in this study. This study uses advanced statistical techniques to test an expanded technology acceptance model (TAM) that incorporates the determinants of perceived usefulness, perceived ease of use, security and privacy, ICT infrastructure and inadequate Internet connectivity, social influence, and demographic profiles. Based on the results, perceived ease of use and ICT infrastructure and Internet connectivity showed positive association with the intention of citizens to adopt smart city services in Jordan. By recognizing the factors that predict citizens’ adoption of smart city services, this study presents some theoretical implications and practical consequences related to smart city service adoption.

Digital services continually evolve to support a growing diversity of users with an ever varying internet-enabled device numbers. The diversity and ambition of digital services is motivated in part by new technology, channels and users within internet enabled smart environments. To address this growing fluidity a co-design approach has been developed that focuses on Government to Citizens (G2C) e-services. Codesign tools and methods are able to maximize opportunities for communicating and collaborating with varied and diverse user groups. A novel G2C e-Service co-design framework is constructed with mechanics for understanding the stakeholder requirements and providing them with an active role throughout the design process. This paper presents a co-design approach with tools and methods that supports wider user participation. The repertory grid technique is used to uncover design process constructs from a diverse group of stakeholder-service users, intermediaries (service interface) and service providers. These constructs are then used to extend the Double Diamond framework before operationalization using Business Process Modelling Notation (BPMN). The conclusions and contributions drawn from this research paper are expected to benefit researchers, by providing user centricity to e-Government service design process, and practitioners, with a systematic framework for supporting the collaboration among stakeholders better design of G2C e-services.
