Vehicle scheduling for rental-with-driver services
2021
Abstract In this paper, we introduce a new vehicle scheduling problem (VSP) with driver consistency faced by rental-with-driver companies. A weekly time-horizon is considered and a set of potential customers, each one associated with a list of required tasks, is assumed. The company can choose to accept or reject a customer, but if accepted, all required tasks must be performed by the same driver. A profit is associated with each customer. The goal is to maximize the company’s total profit, by respecting a list of daily and the weekly drivers’ workload limitations imposed by drivers’ contracts. We propose a mathematical formulation of the problem and design an exact solution method based on…
Transportation Services as Specific Logistics Projects for Oversized Cargo in Poland
2016
Market observation demonstrates that the transportation-freight forwarding-logistics sector carries out diverse projects based on clients’ orders. The majority of those orders are unique and project related. Recently, the project approach to logistics has gained significance. Logistics project management is a relatively new area of knowledge about logistics and supply chains. The paper presents the essence and characteristics of transportation services as a specific logistics project. The authors characterize the transportation-freight forwarding-logistics sector, with particular focus on the sector of oversized cargo transportation. The demand for such services depends on the industry, ene…
Recognizing Early warning Signs in Transportation Services
2018
The transport services can vary in complexity, and can be carried out in short or long supply chains. Market observations indicate that logistics services including transport service become increasingly sophisticated, by far exceeding their traditional perception. They begin to resemble projects characterized by singularity, uniqueness, temporariness, limited budget, and, occasionally, innovativeness. Therefore, they are often treated as a specific type of projects, called logistics projects. The aim of the paper is to present the essence and characteristics of transportation services as a specific logistics project. Author characterizes the transportation service, with particular focus on …
Joint Radio and Computational Resource Allocation in IoT Fog Computing
2018
The current cloud-based Internet-of-Things (IoT) model has revealed great potential in offering storage and computing services to the IoT users. Fog computing, as an emerging paradigm to complement the cloud computing platform, has been proposed to extend the IoT role to the edge of the network. With fog computing, service providers can exchange the control signals with the users for specific task requirements, and offload users’ delay-sensitive tasks directly to the widely distributed fog nodes at the network edge, and thus improving user experience. So far, most existing works have focused on either the radio or computational resource allocation in the fog computing. In this work, we inve…
A Context Aware Learning Application for Communities of Service Technicians
2016
The gathering of knowledge and competences needed to accomplish work related tasks is carried out in several ways. It can be done, planned in the long term to brace oneself for a new area of responsibility or in the short term to prepare for a concrete forthcoming task or while working on a task. The latter two happen quite often at the workplace. In this paper, we present a context aware mobile application supporting workplace learning of service technicians working at different locations including customer service. The originality of the presented application lies in the combination of the question a answering concept with the microlearning concept and in the context awareness of the appl…
An RFID framework for multimodal service provision
2009
In recent years there has been a growing interest toward the development of pervasive and context-aware services, and RFID technology played a relevant role in the context sensing task. We propose the use of RFID technology together with a conversational agent in order to implement a multimodal information retrieval service we call SensorMesh. The information acquired from RFID tags about the nearest point of interest is processed by the conversational agent that carries a more natural interaction with the user, also exploiting a common sense ontology. The service is accessible using a multimodal browser on Personal Digital Assistants (PDAs); the browser allows the user to interact with the…
A speech recognition approach for an industrial training station
2021
This paper presents a speech recognition service used in the context of commanding and guiding the activities around an industrial training station. The entire concept is built on a decentralized microservice architecture and one of the many hardware and software components is the speech recognition engine. This engine grants users the possibility to interact seamlessly with other components in order to ensure a gradual and productive learning process. By working with different API’s for both English and Romanian languages, the presented approach manages to obtain good speech recognition for defining task phrases aiding the training procedure and to reduce the recognition required time by a…
Which Test Artifacts Testing Service Providers should Reuse and How? Experiences from a Case Study in the Chinese ICT Sourcing Market
2011
Software testing service providers are facing new requirements to shorten service times, lower costs, and increase service customization and quality. Reuse of test artifacts is a possible solution that can help providers to meet the requirements because reuse can improve software quality and productivity. However, the extant literature does not explain in depth which test artifacts should be reused and how. This paper focuses on ICT-enabled sourcing of software testing services in the Chinese market to identify the most important reusable test artifacts. There are two reasons for this research. First, most Chinese service providers are small or medium-sized and have to overcome obstacles su…
A Study on Distributed Fault-Tolerant Service Architectures for Critical Software Systems
2021
Reliable systems have been the subject of much research in the past years, with societal dependency on computer systems becoming more and more apparent. With more and more organizations embracing DevOps culture, there is a persistent need to understand how these systems are built and what their trade-offs are. This paper discusses and benchmarks the components of a modern fault tolerant and easily scalable system, designed to maximize up-time. The paper also describes the techniques used in the development of such a system. The system architecture described is implemented through several services deployed for a new critical single sign-on system deployed at CERN (The European Laboratory for…
Skilled workforce scheduling in Service Centres
2009
Abstract The Skilled Workforce Project Scheduling Problem (SWPSP) is a complex problem of task scheduling and resource assignment that comes up in the daily management of many company Service Centres (SC). The SWPSP considers many real characteristics faced daily by the SC: client-company service quality agreements that establish maximum dates for the beginning and the end of tasks with penalties for delays, criticality levels indicating the client-priority in processing each task, generalized precedence relationships that can produce cycle structures, time period and percentage time lags and variable task durations depending on the worker executing the task. Furthermore, the SC workforce i…
