“…The existing literature was reviewed to find a reliable, comprehensive, and detailed set of semantic values. Reviewing the literature to select the values can help us to have a comprehensive and clear set of values [27]. This procedure continued until there were no new values identified in the last 10% of the reviewed materials.…”

The conservation of the architectural heritage has enjoyed a long course of development over the recent decades. Conservation practice is based on the values offered by the architectural heritage resources for different individuals, groups, societies, and governments. Since there is no serious and comprehensive research on the semantic values, the present study was conducted to identify all the influential semantic values in the architectural conservation process and to determine the importance of each value based on the published literature. To this end, more than 100 scientific documents, statements, and charters were analyzed and then, 40 semantic values were identified. The snowball sampling method was used to select the papers. In this study, the qualitative content analysis was used to evaluate the relationship between the architectural heritage and conservation, and the quantitative content analysis was used to assess the relationship between the semantic values and conservation. According to the results of the content analysis, it can be concluded that the conservation of architectural heritage can be investigated and analyzed at three levels: people, experts, and governments, and the holistic conservation of the architectural heritage can be achieved only by the joint cooperation among all the three levels. Also, the results showed that the cultural value, economic value, historical value, and identity greatly influence the semantic conservation of the architectural heritage.

“…Therefore, it is suggested that shifting the IPT units from inefficient routes (Route nos. 3,4,6,11,12) to efficient routes (Route nos. 1, 2, 5, 7, 8, 9, 10, 13) should be done (54)(55)(56).…”

Rapid urbanization, increasing population, and a booming economy have stimulated growth in Indian cites, resulting in higher levels of dependence on private vehicles. This has raised serious issues over the sustainability of transport infrastructure in cities. Public transportation (PT) systems can help achieve sustainable transportation. But they face competition from intermediate public transport (IPT) or Paratransit. The existing PT and IPT systems, therefore, need to re-plan their operations to complement each other and deliver a wider network of services. To achieve this, an evaluation of both PT and IPT systems at microscopic levels is needed to facilitate their possible integration in a coordinated multimodal transportation system. The present paper attempts to evaluate the public and paratransit systems in the city of Surat in the Indian state of Gujarat using a data envelopment analysis (DEA) technique in DEAP software at the individual and system level. The operations, route design, and cost efficiency of both systems are evaluated to understand how well the existing set-up caters to demand. The arithmetic mean of operations, route design, and cost efficiencies of 26 routes of PT system were worked out to be 0.89, 0.94, and 0.69, while that of the 13 routes of the IPT system were 0.92, 0.97, and 0.88 respectively. The system investigation shows that analytically, only 8% of IPT routes were inefficient in all the three aspects, compared with 42% of PT routes. The performance of each route was analyzed, appropriate suggestions made, and the potential of these systems for designing an integrated transport system highlighted.

“…The input and output variables that are chosen in these papers are presented in Table 1. Regarding the input factors in public urban transport, the route length is most often used (Singh et al, 2018;Güner et al, 2016;Deng and Yan, 2019;Lin et al, 2010), as well as fuel costs (Melo et al, 2018;Güner et al, 2016;Adhikari et al, 2018;Zhu et al, 2016;Yu and Chen, 2011;Chiou and Chen, 2006). Based on the selected input and output variables in the published papers and based on the specifics of the analyzed problem in this paper, proposed inputs for the application of the DEA method in agricultural land treatment are aircraft capacity and total cost of treatment of plots in the route.…”

This study employs data envelopment analysis (DEA) approach to evaluate the performance of agricultural aircraft routes. In the context of agricultural aircraft usage, not enough attention has been paid to the efficiency study of the routes in agricultural operations. Aircraft are used in agriculture to perform various treatments on agricultural land. Presumptions in this study are that a land is divided into parcels and one type of treatment must be performed on these parcels. Also, the considered operation is performed by the agricultural aircraft and the size of the analyzed land implies that all parcels cannot be treated in one route, so there are multiple routes which have to be completed. Here, we propose application of output oriented CCR DEA model on one set of routes in order to determine relatively efficient routes. Proposed inputs for the application of the DEA method are: tank capacity of an aircraft and total cost of parcel treatment in one route. Proposed outputs are: total treated land area (total area of all parcels in route) in one route and percentage share of effective flight in the total distance traveled in one route. In this way relatively efficient routes can be selected, and some further analysis of relatively inefficient routes can be made in order to see what changes can be done in inputs and / or outputs of these inefficient routes to improve their performance.
