Article
Flexible transport systems such as Demand Responsive Transit (DRT) are becoming more and more popular over the last few years due to their convenience for customers. However, this convenience comes at a price. Transport authorities are currently looking for ways to improve service flexibility of Conventional Public Transport (CPT), which is undoubt...
Article
Purpose This study aims to propose a framework for identifying and measuring the gaps between evaluation and goal setting in service supply chain (SSC) processes towards planning and development of sustainable tourism aligned with the firm's real conditions and capabilities. Design/methodology/approach By the concept of the service quality gap mod...
Conference Paper
Popularity has increased for semi-flexible transit systems because they combine the flexibility of a Demand Responsive Transit with the affordable fare of Conventional Public Transport. In this study, we investigate a Flex-Route Transit: a shuttle performs several trips in a pre-defined service area; it follows a main route between origin and desti...
Article
The main purpose of this study is to provide a framework for selecting an effective and efficient strategy to reduce the challenges of sustainable business model innovation (SBMI). Firstly, a review of the literature on a set of SBMI strategies and challenges is done. Then by using the Kano model, SBMI strategies are classified. After this, the eff...
Article
The main purpose of this research is to design a multi-level model of service drivers to provide sustainable urban services by considering uncertainty. First, by reviewing the literature, twenty-seven service drivers are identified and using the content analysis approach (CAA) common service drivers are combined and then, a few of them, which requi...
