Abstract

This paper addresses the problem of bunching of buses and how it may be counter-acted. An algorithm is presented for providing selective priority to buses at traffic signals according to their headways, the highest levels of priority being given to those buses with the highest headways, i.e. those buses which are running late or falling behind the bus in front.

Alternative selective priority strategies are evaluated in terms of their effects on bus journey time regularity, bus delay and general traffic delay. A simulation model SPLIT (Selective Priority for Late buses Implemented at Traffic signals) has been developed to investigate the performance of different priority strategies. The paper describes the details of the model, including bus stop dwell times and overlapping bus services, and compares results obtained from the model for a number of different priority strategies.

This work was driven by the keen interest in bus priority applications in London within the EC DGVII project INCOME.

Abstract

Purpose

The purpose of this study is to create a methodological approach for identifying priority areas for science and technology (S&T) development and its empirical application within the city of Moscow. This research uncovers a wide range of multicultural and multidisciplinary global trends that will affect the development of major cities in an era of complexity and uncertainty, including the inherent complexity of urban contexts, demographic and socioeconomic trends, as well as scientific and ecological factors.

Design/methodology/approach

The methodological approach is based on classic foresight instruments. Its novelty lays in the blending of qualitative and quantitative methods specially selected as the most appropriate for the identification of S&T areas in an era of complexity and uncertainty, including horizon scanning, bibliometric analysis, expert surveys and the construction of composite indexes with respect to the scope and resources of the research and the selected object for empirical application – Moscow, which is one of the world’s largest megacities. The analysis was performed for the period of 2009–2018 and expert procedures took place in 2019.

Findings

As a result, 25 global trends were identified, evaluated and discussed over the course of an expert survey and subsequent expert events. Ten priority areas of S&T development were determined, including 62 technological sub-areas within them and the most important market niches for all identified technological sub-areas, which could be useful for the world’s megacities. The results of this study are illustrated using the construction sector. Based on the conducted research and results, a list of recommendations on S&T policy measures and instruments were suggested, including the creation of the Moscow Innovation Cluster, which by the end of 2023 contained more than 6,000 projects and initiatives, selected using the findings of this investigation.

Originality/value

This research contributes to the existing literature and research agenda of setting priorities for S&T development and shows how it can be done for a megacity. The blended foresight methodology that was created within the study satisfies the criteria of scientific originality, is repeatable for any interested researcher, is applicable to any other city in the world and demonstrates its high efficiency in empirical application. It could be used for creating new agenda items in S&T policy, setting S&T priorities for a megacity and integrating the results into decision-making processes. This study provides recommendations on the further implementation of the designed methodology and results into a policymaking system. Moreover, the example of the Moscow Innovation Cluster, which was created based on the results of our research, demonstrates these recommendations’ practical significance in real life, which is quite valuable. The limitation of this study is that it is not devoted to urban planning issues directly or the promotion of R&D areas; it is about setting promising S&T priorities in an era of complexity and uncertainty for megacities.

Abstract

Purpose

This study aims to examine the impact and contribution of priority and non-priority sectors, as well as their sub-sectors, on the gross non-performing assets of public, private and foreign sector banks.

Design/methodology/approach

The Reserve Bank of India's database on the Indian economy is used to retrieve data over 13 years (2008–2021). Public sector (12), private sector (22) and foreign sector (44) banks are represented in the sample. Two-way ANOVA, multiple regression and panel regression statistical techniques are used in SPSS and EViews to examine the data. Further, the results are also validated by using robustness testing by applying the fully modified ordinary least square (FMOLS) and dynamic least square (DOLS) regression.

Findings

The results showed that, for private and foreign banks, the non-priority sector makes up the majority of the total gross non-performing assets, although both the priority and non-priority sectors are substantial for public sector banks. The largest contributors to the total gross non-performing assets in public, private and foreign banks are industries, agriculture and micro and small businesses. The FMOLS displays robustness results that are qualitatively similar to the baseline result.

Practical implications

Based on the study's findings about the patterns of non-performing assets originating from these specific industries, banks might improve the way in which these advanced loans are managed.

Originality/value

There has not been much research done on the subject of sub-sector-specific non-performing assets and how they affect total gross non-performing assets across the three sector banks. The study's primary focus will be on the issue of non-performing assets in the priority’s and non-priority’s sub-sectors, namely, agricultural, micro and small businesses, food credit, industries, services, retail loans and other priority and non-priority sectors.

Abstract

Purpose

The purpose of this paper is to take forward consideration of context in health care priority setting and to offer some practical strategies for priority setters to increase receptiveness to their work.

Design/methodology/approach

A number of tools and methods have been devised with the aim of making health care priority setting more robust and evidence based. However, in order to routinely take and implement priority setting decisions, decision makers require the support, or at least the acquiescence, of key external parties. In other words, the priority setting process requires a receptive context if it is to proceed unhindered.

Findings

The priority setting process requires a receptive context if it is to proceed unhindered.

Originality/value

This paper develops the concept of legitimacy in the “authorising environment” in priority setting and describes strategies which might help decision makers to create a receptive context, and to manage relationships with external stakeholders.

Abstract

Much research has been reported on the possibilities of using various heuristic priority rules to sequence batches through a job shop. The SPT (Shortest Priority Time) heuristic, or modifications to it, has been proved useful in many studies. This paper reports on the results obtained when simulating the work flow through a real machine shop. The simulation model has been used to test the effect on well known priority rules of releasing batches into the shop in order of decreasing expected throughput time. The important effect of this “phased release” of batches was to increase the percentage of batches delivered in finished parts stores on time, particularly in the case where priority rules were in use which might otherwise have resulted in poor delivery. This has important repercussions for management because it implies that by “phased” release of batches in the manner discussed, a large proportion of batches will be delivered on time whatever priority rule is in operation in the shop.

Abstract

Traffic signal control is one of the oldest application areas of fuzzy sets in transportation. In general, fuzzy control is found to be superior in complex problems with multi-objective decisions. In traffic signal control, several traffic flows compete for the same time and space, and different priorities are often set to different traffic flows or vehicle groups

The public transport priorities are a very important part of the effective traffic signal control. Normally, the public transport priorities are programmed by using special algorithms, which are tailor-made for each intersection. The experiences have proved that this kind of algorithms can be very effective if some compensation algorithms and the traffic-actuated control mode are used. We believe that using the fuzzified public transport priority algorithms, the measures of effectiveness of traffic signal control can be even better. In this paper, our fuzzy control algorithm of the public transport priorities will be presented.

Abstract

Purpose

The purpose of this chapter is to describe a method for priority setting that can be used to identify options for disinvestment, and is also meant to serve as a tool for re-allocation of resources to achieve better outcomes with a given pot of resources.

Approach

This chapter draws on findings from the application of a priority setting and resource allocation framework known as Program Budgeting and Marginal Analysis (PBMA). Case studies are used to illustrate key points around implementation including factors for success and guidelines for improving priority setting in practice.

Findings

PBMA has been applied in over 150 settings over the last 30 years. Purposes varied from focusing strictly on disinvestment to examining opportunities for re-allocation. Many organizations report continued use of the framework and decision makers typically express a desire to not revert to historical allocation or political negotiation in deciding on the funding for programs.

Practical implications

Practical implications of this body of work on priority setting abound in that there are significant opportunities to improve resource allocation practice including better engagement of staff, clinicians and public members, greater use of evidence in decision making and improving process transparency.

Social implications

As healthcare resources are limited, particularly in predominantly publicly funded health systems, prudent use of resources is critical. Actually applying the appropriate tools to ensure that funding aligns with organizational and system objectives is paramount.

Originality/value

Although there is a large body of literature on priority setting particularly in countries like the United Kingdom and Canada, this chapter serves to highlight key messages specifically in the context of fiscal constraint and in relation to the concept of disinvestment or service reduction.

Abstract

It has been suggested that “space and artifacts constitute systems of communication which organizations build up within themselves” (Gagliardi, 1992a, b, p. vi) and reflect the cultural life within that organization. This is a study of how the “landscape” of a public library (“Library X”), as an information retrieval system, relates to the values of the people who created it. The efforts here are geared towards understanding the physical instantiation of institutional culture and, more specifically, institutional values as they are reflected through the artifact.
