Minimal learning machine in hyperspectral imaging classification
2020
A hyperspectral (HS) image is typically a stack of frames, where each frame represents the intensity of a different wavelength of light. Each spatial pixel has a spectrum. In the classification of the HS image, each spectrum is classified pixel-by-pixel. In some of the real-time applications, the amount of the HS image data causes performance challenges. Those issues relate to the platforms (e.g. drones) payload restrictions, the issues of the available energy and to the complexity of the machine learning models. In this study, we introduce the minimal learning machine (MLM) as a computationally cheap training and classification machine learning method for the hyperspectral imaging classificatio…
The impact on port competition of the integration of port and inland transport services
2015
The performance of the transport chain is important for the efficiency and competitiveness of an economy. In the context of port competition, there has been an increasing cooperation between firms involved in the intermodal transport chain including seaport services. This paper examines the economic incentives and welfare implications to the integration of port activities with inland transport services under inter-ports competition. Although ports find it advantageous to engage in such integration process it may be detrimental to welfare, since shippers’ aggregate surplus decreases – noting that farther away users benefit at the expense of those closer to the ports. Several scenarios not le…
Financial Evaluation of SLA-based VM Scheduling Strategies for Cloud Federations
2017
In recent years, cloud federations have gained popularity. Small as well as big cloud service providers (CSPs) join federations to reduce their costs, and also cloud management software like OpenStack offers support for federations. In a federation, individual CSPs cooperate such that they can move load to partner clouds at high peaks and possibly offer a wider range of services to their customers. Research in this area addresses the organization of such federations and strategies that CSPs can apply to increase their profit.In this paper we present the latest extensions to the FederatedCloudSim framework that considerably improve the simulation and evaluation of cloud federations. These si…
Various Approaches to Early Contractor Involvement in Relational Contracts
2021
Abstract The main rationale for involving contractors is to apply collaboration to mitigate risk and to harvest opportunities to reduce cost and to increase the project owner’s value. In the paper we argue in the applied analytical model that there are four levels of early contractor involvement (ECI), which are 1) Preparation of the project (before sparking off competition); 2) During the procurement phase (development of what to build); 3) Project delivery model (before construction contract, but after the contractor and designers are selected); 4) Project delivery model (where involvement also continues in the execution phase). In the paper we argue that category 4 have the largest poten…
Managing Organizational Growth and Dynamic Complexity
2016
Managers, entrepreneurs and administrators are often reluctant to invest time in order to frame the future of their own organization. They may look too much focused on reducing the complexity of current management. The vision of the future they create in their own minds may remain unchanged even for many years, or may incrementally and ambiguously change, with no effort on learning, on perceiving the early symptoms of crises, and assessing the sustainability of organizational growth rate.
Applying Dynamic Performance Management to Public Emergency Management: An Analysis of the Wenchuan Earthquake
2020
Previous studies in public emergency management confirm that collaboration assumes a relevant role in strengthening society’s capacity to cope with complex phenomena, such as disasters. However, empirical researches on emergency management show problems in performance measurement, mainly in employing narrow measures focusing on the results of single organisations rather than the entire system. Starting from a Chinese earthquake (Wenchuan) case, as an example, we use the dynamic performance management approach to develop a performance framework. This framework aims at investigating the interrelationships of different actors involved in emergency management and designing appropriate public em…
Experimenting lean dynamic performance management systems design in SMEs
2018
Purpose The purpose of this paper is to frame the potential benefits of lean dynamic performance management (PM) systems for small and micro-enterprises. Such systems may exploit the entrepreneur’s tacit knowledge and build on managerial competencies, by incorporating individual attributes into organisational routines. Design/methodology/approach The paper suggests the use of insight models based on the combination of lean PM tools and system dynamics (SD) modelling. Based on a number of exemplary cases, the paper discusses the potential benefits of these models, in respect to four specific contexts: artisan, new company start-up, established firm and micro-giant company. Related to such c…
Collaborative Business Model Innovation Process for Networked Services
2013
This paper presents a process framework for innovating joint business models (co-BM) for multiple companies. Our framework describes the change management that should be carried out in parallel to the rigorous analysis and development of the business model details. With two illustrative cases we show that fruitful co-BM creation process in networks requires both development of the model itself, but also organizational innovation processes including mutual learning and harmonisation of operations. We claim that by understanding this dual process and its key facets might help (1) to coordinate the practical BM creation projects better and (2) to analyse which BM related decisions contribute o…
Benchmarking the port services: a customer oriented proposal
2004
In recent years, ports have experienced a period of significant growth and development along with intense inter‐port rivalry as a consequence of intermodality and hinterland development. It is therefore vital that port management bodies define and implement suitable strategies. This paper aims to adapt the benchmarking technique to the sphere of ports. Compares the activity of a port with that of its competitors, which is considered to be excellent. This is a strategic approach where consideration of the needs of the client, shipping lines and export‐import companies is the axis of the benchmarking process.
Creating Business Value from Cloud-Based ERP Systems in Small and Medium-Sized Enterprises
2019
Part 11: Modelling and Managing the Digital Enterprise; International audience; This qualitative study focuses on how small- and medium-sized enterprises (SMEs) can realize benefits and create information technology (IT) value by investing in cloud enterprise resource planning (ERP) systems. We interviewed 19 respondents from cloud providers and cloud clients and found that their SMEs experienced both benefits and challenges when implementing cloud ERP systems. The digital value was obtained through work process automatization, fast updates of system functionalities, enhanced security of data storage, and increased access to critical business data from multiple digital units. Challenges in …
