The static share-a-ride problem (SARP) consists of handling people and parcels in an integrated way through the same vehicle, which provides a shared trip between an origin and a destination, in response to requests received in advance. When multiple providers compete on the same market (for instance, within the same city or region), horizontal cooperation can be an efficient strategy to consolidate all requests and to optimize the total payoff. This situation gives rise to the cooperative SARP (coop-SARP). In this problem, multiple depots and heterogeneous vehicles must be considered and different cooperation levels may be agreed upon by service providers. In this paper, we propose a new mathematical programming formulation for cooperative SARP along with theoretical bounds. Moreover, through numerical experiments and ad hoc statistics, we analyze the benefits of different levels of horizontal cooperation between service providers. The results show that cooperation leads to reduced travel times and to improved vehicle occupancy rates, service levels, and profits, which make such a cooperative system even more appealing for service providers.

Adoption of development agendas at different levels – national, regional, continental, and global level – has led to an unprecedented increase in demand for official statistics. This increase has not only brought to the fore a litany of challenges facing National Statistical Systems (NSSs) in Africa but also it has created opportunities for strengthening statistical production and development. This paper underscores the need for countries to take full advantage of these opportunities and increase investments in statistics, undertake data innovation, and expand and diversify data ecosystems, leveraging on the foundations of the data revolution for sustainable development and in line with current international statistical frameworks. The paper posits that these improvements will not happen coincidentally nor through ad hoc, piecemeal and uncoordinated approaches. Rather they will happen through more systematic, coordinated and multi-sectoral approaches to statistical development. The National Strategy for the Development of Statistics (NSDS) is presented as a comprehensive and robust framework for building statistical capacity and turning around NSSs in African countries. The paper unpacks the NSDS; elaborates the NSDS processes including; mainstreaming sectors into the NSDS, the stages of the NSDS lifecycle and the role of leadership in the NSDS proces; highlights NSDS extension; presents the design and implementation challenges, and the key lessons learned from the NSDS processes in Africa in the last 15 years or so.

Current advancements in cellular technologies and computing have provided the basis for the unparalleled exponential development of mobile networking and software availability and quality combined with multiple systems or network software. Using wireless technologies and mobile ad-hoc networks, such systems and technology interact and collect information. To achieve the Quality of Service (QoS) criteria, the growing concern in wireless network performance and the availability of mobile users would support a significant rise in wireless applications. Predicting the mobility of wireless users and systems performs an important role in the effective strategic decision making of wireless network bandwidth service providers. Furthermore, related to the defect-proneness, self-organization, and mobility aspect of such networks, new architecture problems occur. This paper proposes to predict and simulate the mobility of specific nodes on a mobile ad-hoc network, gradient boosting devices defined for the system will help. The proposed model not just to outperform previous mobility prediction models using simulated and real-world mobility instances, but provides better predictive accuracy by an enormous margin. The accuracy obtained helps the suggested mobility indicator in Mobile Adhoc Networks to increase the average level of performance.

Chinese tourists visit that increase each year have led to numerous impacts on the tourism industries, such as increasing the opportunities to invest in building more accommodation facilities to accommodate the influx. In addition to the development, there are also negative effects caused by it, such as intense competition among service providers to meet the level of occupancy. NDBH as one of the best hotels in Bali is quite keen to see these opportunities, by making advantage of the Chinese tourists visit in Bali. The research was conducted to study their potential room occupancy in NDBH to the viewpoint of academic realm. 2) Perform arguments proofing on negative issue of the scholars’ thinking paradigm on our current tourism concerning the Chinese tourists. By using SWOT analysis it is found out that: 1) The strength of Chinese tourists rely on its huge population, a positive contributions against occupancies, and diverse classification of Chinese tourists, 2) The weaknesses of the Chinese tourists are; they are having lack of Behavior, They speaking influent English, and they tend to make reservation in a short notice, 3) Opportunities of Chinese tourists are; travel agents are distributing many Chinese tourists in Bali making them accessible, and group of Chinese tourists help boost occupancy rates, 4) The threat of Chinese tourists are; it is likely to harm the Cross Culture of the hotel, Chinese travelers are not a loyal customer (Price Oriented), operational processes has hampered hotels, and hotel loss profit on sub-department. Hopefully this research can help interested parties, especially those who deal directly with tourists from China, in order to take appropriate measures and policies in the future.

Long-term care (LTC) must be carefully delineated when expenditures are compared across countries because how LTC services are defined and delivered differ in each country. LTC’s objectives are to compensate for functional decline and mitigate the care burden of the family. Governments have tended to focus on the poor but Germany opted to make LTC universally available in 1995/1996. The applicant’s level of dependence is assessed by the medical team of the social insurance plan. Japan basically followed this model but, unlike Germany where those eligible may opt for cash benefits, they are limited to services. Benefits are set more generously in Japan because, prior to its implementation in 2000, health insurance had covered long-stays in hospitals and there had been major expansions of social services. These service levels had to be maintained and be made universally available for all those meeting the eligibility criteria. As a result, efforts to contain costs after the implementation of the LTC Insurance have had only marginal effects. This indicates it would be more efficient and equitable to introduce public LTC Insurance at an early stage before benefits have expanded as a result of ad hoc policy decisions.

PurposeThe purpose of this study is to identify the practices used by service providers to manage the customer service experience (CSE) across multiple phases of the customer journey in a business-to-business (B2B) setting.Design/methodology/approachThis study comprises an ethnography that investigates in real time, from a dyadic perspective, and the CSE management practices at two service providers operating in knowledge-intensive service industries over a period of eight months. Analytically, the study concentrates on critical events that occurred in phases of the customer journey that in some way alter CSE, thus making it necessary for service providers to act to keep their customers satisfied.FindingsThe study uncovers four types of service provider practices that vary based on the mode of organization (ad hoc or regular) and the mode of engagement (reactive or proactive) and based on whether they restore or bolster CSE, including the recurrence of these practices in the customer journey. These practices are conveniently presented in a circumplex typology of CSE management across five phases in the customer journey.Research limitations/implicationsThis paper advances the research in CSE management throughout the customer journey in the B2B context by showing that CSE management is dynamic, recurrent and multifaceted in the sense that it requires different modes of organization and engagement, notably during interaction with customers, in different phases of the customer journey.Practical implicationsThe circumplex typology acts as a tool for service providers, helping them to redesign their CSE management practices in ongoing service and dialogical processes to keep their customers more engaged and satisfied.Originality/valueThis paper is the first to infuse a dyadic stance into the ongoing discussion of CSE management practices in B2B, in which studies to date have deployed only provider or customer perspectives. In proposing a microlevel view, the study identifies service providers' CSE management practices in multiple customer journey phases, especially when the situation becomes critical.

<p>This paper investigates the price effect to the charging demand coming from electric vehicles and then evaluates the performance of a pre-reservation mechanism using the real-life demand patterns. On the charging network in Jeju city, the occupancy rates for 3 price groups, namely, free, medium-price, and expensive chargers, are separated almost evenly by about 9.0 %, while a set of chargers dominates the charging demand during hot hours. The virtual pre-reservation scheme matches electric vehicles to a time slot of a charger so as not only to avoid intolerable waiting time in charging stations systematically but also to increase the revenue of service providers, taking into account both bidding levels specified by electric vehicles and preference criteria defined by chargers. The performance analysis results obtained by prototype implementation show that the proposed pre-reservation mechanism improves the revenue of service providers by up to 9.5 % and 42.9 %, compared with the legacy FCFS and reservation-less walk-in schemes for the given performance parameter sets.</p>

Purpose This paper aims to investigate the moderating role of co-creation in the implementation of servitization strategies in the pharmaceutical industry in a business-to-business (B-to-B) context. More specifically, this investigation explores the impact of different levels of services (base, intermediate and advanced) on servitization and on performance by using co-creation as a moderating factor. Design/methodology/approach A research framework was developed and empirically tested in the pharmaceutical sector. Data collection was conducted through the online distribution of questionnaires. The final sample included 219 pharmacy stores, and the data were analysed using structural equation modelling. Findings Main findings suggest that when the level of co-creation of the design of services is high, there are significant effects of servitization on firm performance. The moderating effect of co-creation is illustrated in regard to intermediate and advanced services, but results referring to the impact of intermediate services on servitization appear non-significant with a low degree of co-creation. No significant effects could be found for the impact of base services on performance and servitization for both high and low degrees of co-creation. Findings show an impact of advanced services on performance through the mediating effect of servitization when the degree of co-creation is high. Originality/value Most research concerning servitization has been done from the perspective of manufacturers and service providers. This study adds value to the literature because it was designed from a customer’s perspective. Moreover, it contributes towards the conceptualization of the servitization research strategy and business models in a B2B context. This is accomplished through the investigation of the moderating effect of co-creation on the impact of the different levels of services on servitization and on performance.

The 2000s have seen the increased development of a different type of logistics service providers known as fourth party logistics (4PL) service providers. Those providers are now very involved in the short-term “transient” logistics needed by large retailers to organize the supply chain for some of their promotional activities that only last few days, or NGO to organize efficient relief operations after a disaster. Hence, 4PL firms can be considered dynamic assemblers of logistical resources they capture from partners in order to satisfy clients. A major criterion required for a successful 4PL intermediation is trust, as key element of social capital, and this chapter discusses the importance of trust in the efficient operations of this transient or ad hoc relationship between the 4PL and the client.

A traditional service provider of telecommunications is recognized as an authority which is trusted by the subscribers and the public. Ad hoc and Peer to Peer (P2P) networks have demonstrated advantages that service provider controlled networks lack, and they also exhibit self-organizing behaviors. A pure self-organizing network does not rely on any hierarchical management. Instead, it utilizes a web of trust for security. Its trust management is complicated and varies from node to node. In this article, we discuss a hybrid trust structure that leverages the involvement of an authority in a self-organizing network to increase trust levels between disconnected small-worlds. The new model will help service providers design more robust and innovative solutions for next generation networks and applications.
