Designing a viable carsharing system in a competitive environment is challenging and often dependent on a myriad of decisions. This paper establishes and presents an integrated conceptual decision-support framework for carsharing systems, encompassing critical decisions that should be made by carsharing organizations and users. To identify the main decisions in a carsharing system, and the inputs and interactions among them, it is crucial to obtain a comprehensive understanding of the current state of the literature as well as the business practices and context. To this aim, a holistic and in-depth literature review is conducted to structure distinct streams of literature and their main findings. Then, we describe some of the key decisions and business practices that are often oversimplified in the literature. Finally, we propose a conceptual decision-support framework that systematizes the interactions between the usually isolated problems in the academic literature and business practices, integrating the perspectives of carsharing organizations and of their users. From the proposed framework, we identify relevant research gaps and ways to bridge them in the future, toward more realistic and applicable research.

在竞争环境中设计可行的汽车共享系统具有挑战性，并且通常取决于众多决策。本文建立并提出了一个针对汽车共享系统的综合概念性决策支持框架，其中包括汽车共享组织和用户应做出的关键决策。为了确定汽车共享系统中的主要决策以及它们之间的输入和交互作用，至关重要的是要全面了解文献的当前状态以及业务实践和环境。为此，进行了全面深入的文献综述，以构建独特的文献流及其主要发现。然后，我们描述一些关键决策和业务实践，而这些决策和业务实践通常在文献中被过分简化。最后，我们提出了一个概念性的决策支持框架，该框架将学术文献中通常孤立的问题与业务实践之间的相互作用系统化，并整合了汽车共享组织及其用户的观点。从提出的框架中，我们确定了相关的研究差距和弥补未来的差距的方法，以便朝着更加现实和适用的研究方向发展。
