Abstract

Purpose

Being the final end of the logistic distribution, attended home delivery (AHD) plays an important role in the distribution network. AHD typically refers to the service provided by the distribution service provider to the recipient's doorstep. Researchers have always identified AHD as a bottleneck for last-mile delivery. This paper addresses a real-life stochastic multi-objective AHD problem in the context of the Indian public distribution system (PDS).

Design/methodology/approach

Two multi-objective models are proposed. Initially, the problem is formulated in a deterministic environment, and later on, it is extended to a multi-objective AHD model with stochastic travel and response time. This stochastic AHD model is used to extensively analyze the impact of stochastic travel time and customer response time on the total expected cost and time-window violation. Due to the NP-hard nature of the problem, an ant colony optimization (ACO) algorithm, tuned via response surface methodology (RSM), is proposed to solve the problem.

Findings

Experimental results show that a change in travel time and response time does not significantly alter the service level of an AHD problem. However, it is strongly correlated with the planning horizon and an increase in the planning horizon reduces the time-window violation drastically. It is also observed that a relatively longer planning horizon has a lower expected cost per delivery associated.

Research limitations/implications

The paper does not consider the uncertainty of supply from the warehouse. Also, stochastic delivery failure probabilities and randomness in customer behavior have not been taken into consideration in this study.

Practical implications

In this paper, the role of uncertainty in an AHD problem is extensively studied through a case of the Indian PDS. The paper analyzes the role of uncertain travel time and response time over different planning horizons in an AHD system. Further, the impact of the delivery planning horizon, travel time and response time on the overall cost and service level of an AHD system is also investigated.

Social implications

This paper investigates a unique and practical AHD problem in the context of Indian PDS. In the present context of AHD, this study is highly relevant for real-world applications and can help build a more efficient delivery system. The findings of this study will be of particular interest to the policy-makers to build a more robust PDS in India.

Originality/value

The most challenging part of an AHD problem is the requirement of the presence of customers during the time of delivery, due to which the probability of failed delivery drastically increases if the delivery deviates from the customer's preferred time slot. The paper modelled an AHD system to incorporate uncertainties to attain higher overall performance and explore the role of uncertainty in travel and response time with respect to the planning horizon in an AHD, which has not been considered by any other literature.

Abstract

Purpose

In the modern era of e-grocery, attended home delivery (AHD) has been identified as a crucial part of the last-mile delivery problem. This paper aims to deal with a real-life last-mile-delivery problem in the context of the Indian public distribution system (PDS). The authors identified two different environments for the said AHD problem and proposed two different approaches to address the issue under these problem settings.

Design/methodology/approach

In this study, the authors first consider the problem in a static environment and propose an iterated local search (ILS) integrated with an adaptive large neighborhood search (ALNS) meta-heuristic algorithm to obtain a routing solution. Thereafter, they extend the study in a dynamic environment where new delivery requests occur dynamically and propose a heuristic algorithm to solve the problem. For the dynamic case, multiple scenarios for the occurrence of delivery requests are considered to determine decisions regarding the opportunity to include a new request into the current solution.

Findings

By computational experiments, the authors show that the proposed approach performs significantly well for large size problem instances. They demonstrate the differences and advantages of the dynamic problem setting through a set of different scenarios. Also, they present a comparative analysis to show the benefits of adopting the algorithm in dynamic routing scenarios.

Research limitations/implications

Future research may extend the scope of this study by incorporating stochastic delivery failure probabilities and customer behavior affecting the delivery response. Also, the present study does not take inventory policies at the depot into consideration. It will be of interest to see how the system performs under the uncertainty of supply from the depot. Despite the limitations, the authors believe that this study provides food for thought and encouragements for practitioners.

Practical implications

This study shows the benefits of adopting an AHD problem in a dynamic setting in terms of customer service as compared to a traditional static environment. The authors clearly demonstrate the differences and advantages of the dynamic problem setting through a set of different scenario analysis.

Social implications

This paper investigates a real-life AHD problem faced by the Department of Food, Supply and Consumer Affairs, India. The findings of this study will be of particular interest to the policy-makers to build a more robust PDS in India.

Originality/value

The study is unique and highly relevant for real-world applications and can help build a more robust AHD system. Also, the proposed solution approaches to aid the problem in both static and dynamic routing scenarios will be of particular interest to practitioners.

Abstract

Purpose

The purpose of this paper is to discuss the importance of documentation for digital humanities resources. This includes technical documentation of textual markup or database construction, and procedural documentation about resource construction.

Design/methodology/approach

A case study is presented of an attempt to reuse electronic text to create a digital library for humanities users, as part of the UCIS project. The results of qualitative research by the LAIRAH study on provision of procedural documentation are discussed, as also is, user perception of the purpose, construction and usability of resources collected using semi‐structured interviews and user workshops.

Findings

In the absence of technical documentation, it was impossible to reuse text files with inconsistent markup (COCOA and XML) in a Digital Library. Also, although users require procedural documentation, about the status and completeness of sources, and selection methods, this is often difficult to locate.

Practical implications

Creators of digital humanities resources should provide both technical and procedural documentation and make it easy to find, ideally from the project web site. To ensure that documentation is provided, research councils could make documentation a project deliverable. This will be even more vital once the AHDS is no longer funded to help ensure good practice in digital resource creation.

Originality/value

Previous work has argued that documentation is important. However, the paper presents actual evidence of the problems caused by a lack of documentation and shows that this makes reuse of digital resources almost impossible. This is intended to persuade project creators who wish resources to be reused to provide documentation about its contents and technical specifications.

Abstract

Purpose. There are a large number of free electronic resources available on the web, from various sources, including the outputs of funded research projects. As yet, there are not well‐established procedures for the evaluation of the quality and usefulness of these electronic resources. This article examines two preliminary approaches to the problem. Approach. An investigation into free e‐books was carried out for the JISC to examine the potential for the use of free e‐books in teaching and learning in further and higher education in the UK. Questionnaires, a dissemination workshop and focus groups were used to obtain the research results. Three possible approaches to evaluation are discussed, involving the collection of high‐quality resources in a trusted repository, large‐scale evaluation of available resources, and evaluation by end‐users. The practical problems of each approach are discussed. The prospect of future large‐scale digitisation projects and their possible impact in this field is also considered. In a separate section, the question of evaluation of electronic resources is briefly considered in the context of collections development in the Arts and Humanities Data Service (AHDS). Findings. The conclusion is drawn that it is more cost‐effective to intervene early in the lifecycle of a digital resource and to help ensure good practice in the creation of the resource than to attempt to evaluate and enhance a resource at the end of the creation process. Originality. This paper draws on the unique experience of the AHDS as a central, national service for researchers in the arts and humanities creating and using electronic resources.

Abstract

Purpose

The purpose of this paper is to show the gap between the authorised heritage discourse (AHD) as practised within Norwegian heritage management and the recommendations forwarded by UNESCO for the managing of the historic urban landscape (HUL), indicating that a shift is necessary to manage dynamic urban change.

Design/methodology/approach

A current development initiative in Oslo is used to show how heritage values can be differentiated by a spatial scale to prioritise between heritage goods at a practical level and as an attempt to balance financial interests and the values identified by heritage criteria.

Findings

The scaling of heritage assets is useful for distinguishing between different levels or types of value (cultural/economic, private/social/public) but is not sufficient for obtaining the aims forwarded by UNESCO within an AHD that does not support development of HULs. A contextual understanding of heritage value must be obtained to make heritage a vital resource in the contemporary urban context.

Practical implications

A broader understanding of what constitutes the urban environment, including economic viability, seems mandatory to make the current Norwegian practice of heritage management more adaptive to the dynamic nature of living cities and the ambitions reflected in the recommendations from UNESCO.

Originality/value

Integrating development potential as a criterion adds a dynamic aspect to the valuation of heritage not sufficiently present in the current practice and literature.

Abstract

Purpose

The purpose of this article is to discuss the results of the Log Analysis of Internet Resources in the Arts and Humanities (LAIRAH) study. It aims to concentrate upon the use and importance of information resources, physical research centres and digital finding aids in scholarly research.

Design/methodology/approach

Results are presented of web server log analysis of portals for humanities scholars: the arts and humanities data service (AHDS) website and Humbul Humanities Hub. These are used to determine which resources were accessed most often, or seldom. Questionnaire data about perceptions of digital resource use were also gathered.

Findings

Information resources such as libraries, archives museums and research centres, and the web pages that provide information about them are vital for humanities scholars. The university library website was considered to be the most important resource, even compared to Google. Secondary finding aids and reference resources are considered more important than primary research resources, especially those produced by other scholars, whose output is less trusted than publications produced by commercial organisations, libraries, archives and museums.

Practical implications

Digital resources have not replaced physical information resources and the people who staff them, thus both types of information continue to require funding. Scholars trust the judgment of information professionals, who therefore need to be trained to evaluate and recommend specialist digital research resources.

Originality/value

LAIRAH was the first research project to use quantitative data to investigate resource use. Findings about the type of resources used are based on evidence rather than opinions alone. This gives a clearer picture of usage that may be used to plan future information services.

Abstract

While granting Cowper the full poetic license he is entitled to, prosaically I must observe that it is not the syllables but rather the philogists who pant. They do indeed breathe rapidly in short gasps after they have established each successively deeper level of root connection in pursuit of the etymological purpose of delineating the origin and historical development of words, or of providing an account of any given word. Etymology as so defined I will designate analytic etymology and distinguish from another form of word study, which I shall call reconstructive etymology.
