The study proposes an evaluation model that allows quantitative characterization of the effects of service quality on consumer’s satisfaction for online food delivery (OFD) services in a nonlinear manner. As such, the authors endeavor to bridge the research-to-practice gaps whereby the effect magnitudes and nonlinear patterns of service quality have been overlooked in the current literature.

The quantitative Kano method is adopted. A Kano questionnaire was first developed by synthesizing and operationalizing existing evidence on OFD service qualities. The questionnaire solicited consumers’ evaluations of 21 OFD service attributes, and it was distributed to an online panel in Singapore. With 580 valid responses, the functions that quantitatively depict effects of each attribute on consumer’s satisfaction were subsequently derived.

The results reveal that among Singaporean consumers, food quality, reliability of delivery, responsiveness of customer support, ease-of-use of digital interfaces and promotions are pivotal attributes contributing to above-average satisfaction improvement across all performance levels. Meanwhile, delivery riders’ attitudes and real-time tracking functions emerge as substantial contributors to satisfaction at high-performance levels.

The findings provide crucial insights for OFD practitioners in Singapore in resource prioritization and service optimization. This study demonstrated the importance of streamlining customer support services and focusing on the utilitarian aspects of OFD services. Moreover, these results can be employed in advanced service improvement procedures, providing a roadmap for future OFD service enhancements.

This study pioneers the development of a quantitative quality evaluation model in the OFD context. With the established quantitative Kano model, the study addresses the omission of effect magnitudes and nonlinear patterns of service quality. It highlights the transition from a binary “does it affect satisfaction” to a more nuanced “how much does it affect satisfaction” approach, offering a robust understanding of consumer’s satisfaction dynamics.

Omni-channel shopping affords consumers a variety of delivery options to receive products based on their preferred times and locations. By considering consumers' contributions (physical, social and attentive efforts) in co-creating delivery services, this study investigates their preferences for parcel delivery.

A scenario-based questionnaire survey is conducted for data collection in Singapore (n = 483). Furthermore, a multinomial logistic regression is performed to assess consumers' choice mode of delivery among five alternatives, that is attended home delivery, unattended home delivery, automated self-collection locker, attended pickup point and click-and-collect.

Compared to attended home delivery, consumers who choose the alternatives are found to be more willing to contribute physical effort but less interested in responding attentively to informational updates. Efforts required for social interactions discourage consumers from choosing attended deliveries, prompting unattended alternatives (e.g. home delivery and self-collection) as more attractive choices. Additionally, socio-demographic factors and product value also influence consumers' preferences.

This study contributes to the literature by integrating the theoretical concept of consumer logistics into omni-channel studies, providing a new approach to examining consumers' channel behaviour. With detailed profiling that links product value and consumers' socio-demographics to their choice mode of delivery, the authors create practical insight into the optimal design of omni-channel distribution systems that best harness consumers' voluntary contributions.

The advent of digitalization and the trend of social distancing coincide with the individualized lifestyle that is emerging among contemporary shoppers. This study explores the unique market of “smart solo shoppers”. Two empirical studies are conducted, which aim to identify the major dimensions of multi-channel shopping activities that are engaged by the shoppers (Study 1, n = 64) and to differentiate the shoppers' valuation of time invested in the distinct dimensions under different cultural influences (Study 2, n = 519).

A survey questionnaire is used for data collection, and data are analyzed using structural equation modeling.

Results reveal that the shopping activities converge into four principal dimensions: offline shopping, online shopping, post-shopping delivery and product return activities. Shoppers who perceive offline shopping activities as a time burden and online shopping and delivery activities as venues of value creation are more strongly self-identified as smart solo shoppers. Furthermore, smart solo shoppers who are under a strong influence of individualistic culture are found to spend time on multi-channel shopping to make the right purchase the first time, whereas shoppers perceiving being in a weak individualistic culture prefer to engage online channels while being prepared to return the unwanted purchases.

This study highlights an emerging research field in the nexus of solo consumption and smart shopping. Emphasizing the utility-driven and ego-expressive nature of smart solo shoppers, the authors provide an initial profile of these shoppers based on their time-valuation patterns and the contextual impacts of individualistic culture.

The purpose of this paper is to provide a risk assessment of port-centric threats that may have adverse effects on supply chain continuity from the perspectives of port operators and port users, thereby determining the significance of these threats to supply chain disruptions.

Drawing on literature review and reported cases, 19 port-centric disruptive events were identified. Subsequently, surveys were conducted to collect data from 102 port operators and 123 port users worldwide on the frequencies and consequences of the identified port-centric disruptive events. Risk matrices were then generated to compare the perspectives of port operators and port users.

The results show that threats related to the planning of port resources require the highest level of attention. This highlights important areas for port managers seeking to improve port resilience and supply chain continuity through a more prudent management of risks.

The results help port managers understand where they should establish strategic capability to increase port resilience and enhance sustainability to benefit port users. However, the study could be further enhanced by evaluating the threats based on different regions of ports and port users and making recommendations for port operators to undertake.

The findings of this paper are significant as they provide an analysis of data gathered from international port operators and port users. Risk matrices have been widely applied in many industries, yet no studies have been conducted to develop a portfolio of port-centric risks at a scale as large as this paper.

E-commerce last-mile logistics is undergoing dramatic changes. By inviting consumers to participate in self-collection, they collectively form a mass crowd of resources that can be integrated into last-mile logistics. However, consumers' participation may lead to a spectrum of value outcomes from value co-creation to co-destruction. Therefore, the purpose of this paper is to critically examine the value formation process focussing on micro-level practices and resource outcomes.

Anchored on practice theory and resource conservation theory, content analysis is adopted to analyse 546 practice-based experiences extracted from a leading social media platform.

The analysis reveals five sequential practices of self-collection: purchasing, delivering, notifying, receiving and confirming. Furthermore, the co-created practices are characterised by gains in material, esteem, social and energy resources of the interacting actors. Meanwhile, the co-destructed practices cause a chain of resource losses, where the interacting actors suffer primary losses which subsequently triggers consumers' coping behaviours and further destroys resources for all.

Focussing on constituent service practices, this study zooms into the value formation process. The authors contribute to logistics literature with a service-dominant logic by stressing end-consumers' involvement in the creation and consumption of last-mile logistics.

This study conceptualises the sources and consequences of the nuanced service practices (value formation or destruction) of self-collection. A unified framework is thus proposed, which guides logistics service providers to channel consumers towards more constructive participation in last-mile logistics.

Increasingly, the logistics industry offers innovative solutions that interact with end-consumers directly. The purpose of this paper is to examine the consumer participation behaviour in co-creating logistics service values, using self-collection via automated parcel station as an example. Built on the synthesised insights from logistics studies and behavioural theories on consumers’ attitude and affect, the effect of cognitions (what consumers think) and affects (what consumers feel) are investigated.

A total of 500 valid responses are collected from an online panel of respondents and the data are analysed using exploratory factor analysis and structural equation modelling.

Consumers’ affects towards participation are stronger motivations that not only intrinsically motivate consumers to participate but also exert an indirect influence via consumers’ cognitions.

To elicit consumers’ affections, it is critical to create enjoyable (enjoyment), assuring (assurance) and secure (security) service experiences. On the other hand, an overly straightforward service offering (in terms of cognitive functionality), void of the aforementioned experiences, may discourage consumers from participation.

This research unveils consumer participation in co-creating logistics service values, contributing to studies on the emerging phenomenon of consumer logistics. A rebalancing of the logistics research from a utility-creation perspective to an experience-creation perspective has been advocated.

Although a dominant marketing concept, value co-creation (VCC) is not without controversy. Inspired by value co-destruction (VCD), the purpose of this paper is to review the scattered literature on the uncertainties in collaborative value formation, synthesising contingency factors of value outcomes in VCC.

The paper is based on an examination of 84 peer-reviewed journal articles. Recognising the drawbacks of the macroscopic abstraction in existing the VCC literature, the authors adopt a zooming-in approach to identify distinct patterns of contingency factors in the collaborative value-formation process.

From a macro-social perspective, VCC may connote a sense of exploitation of “consumers” and a need for consumer control of “producers”, impeding harmonious value formation. Zooming into actor-to-actor interactions, the collaborative relationship is found to be a source of uncertainties in value formation, which is further complicated by differences in the knowledge intensities of services. Finally, reviewing the individual consumer reveals a most nuanced picture that demonstrates heterogeneities of consumers’ VCC involvement and complexities in their perceptions and behaviours. Five propositions and a contingency framework are proposed.

Six value formation mechanisms are proposed based on interconnected and multi-level perspectives, providing implications for managers and future researchers.

This paper contributes to rebalancing VCC research by synthesising insights on the potential contingencies, which are relatively under-explored yet vital to keep the controversy alive and relevant, and re-invigorating business processes.

As an application of self-service technology, automated parcel station (APS) is emerging as a logistics innovation to address the inefficiency and delivery failure in conventional home delivery. However, the long-term viability of APS depends on the consumers’ acceptance of such concept. In response, the purpose of this paper is to conduct a behavioural study on consumers’ adoption of self-collection service via APS.

By synthesising theoretical insights from the innovation diffusion literature and attitude theories, a conceptual model is developed and empirically validated. Perceived characteristics of APS are present to directly influence the consumers’ adoption intention, or indirectly through attitude. A total of 170 valid responses are collected from a survey conducted in Singapore and the data are analysed using structural equation modelling.

Consumers’ favourable attitude and perceived relative advantage of APS directly lead to stronger adoption intention. On the contrary, consumers’ perceptions on compatibility and trialability and on complexity indirectly influence their adoption intention via attitude, in a positive and in a negative way, respectively. Additionally, attitude is found to be the most influential factor contributing to consumers’ adoption intention.

The scope of this paper is limited to e-consumers’ initial adoption decision. Future research should examine the consumers’ adoption behaviour further down the innovation adoption process, such as continuance and commitment.

This research conceptualises and validates the consumers’ adoption behaviour of APS from a synthesised view of innovation diffusion and attitude theories, theoretically and empirically contributing to the field of study on logistics innovations from the consumers’ perspective.

Service conveniences (SCs) play a deterministic role in motivating consumers’ participation in self-collection (via attended pickup points or unattended automated locker systems). Accordingly, the SERVCON model provides a multi-dimensional conceptualisation of SCs, whereas the Kano model explains consumers’ satisfaction formation in response to multi-dimensional service attributes. Anchored on synthesised insights of both models, the purpose of this paper is twofold: first, to qualitatively apply the SC concept to develop specific service attributes of self-collection; and second, to quantitatively examine these attributes in relation to consumers’ satisfaction formation.

A quantitative Kano model is adopted for survey questionnaire design and data analysis, and 500 valid responses are obtained from an online panel of respondents in Singapore.

SCs are decomposed into 11 service attributes reflecting access, benefit, transaction and post-benefit conveniences of self-collection services. Distinctive patterns of satisfaction formation are revealed in response to specific service attributes; for example, consumers are most responsive to improvement in transaction convenience. Furthermore, as service performance level increases, benefits of spatial accessibility diminish, whereas those of temporal accessibility increase.

This study reveals key service attributes influencing the self-collection services’ convenience and impact on consumers’ satisfaction. Guidelines are presented for designing an optimal resource allocation strategy for logistics service providers to promote self-collection services.

This study synthesises diverse logistics literature on self-collection services under the central theme of SCs, thus enriching the conceptual development of SCs with a decomposed framework of logistics service attributes.
