a layered protocol architecture for scalable innovation and identification of network economic synergies in the internet of things
2016Co-Authors: Tilman Wolf, Anna NagurneyAbstract:Many solutions to important societal problems relating to the environment, health care, transportation, etc. seek to utilize the promises of the Internet of Things (IoT), where sensing, computation, and actuation merge the physical world with the computational world. To date, many such solutions have focused on a single problem domain and require dedicated sensor and actuator infrastructure. This vertical Integration makes the development of innovative, novel solutions costly and difficult to deploy. An architectural approach to addressing this challenge is to enable Horizontal Integration, where sensors and actuators from different applications can interconnect with any computational IoT application. In order to isolate complexities and to support heterogeneous systems and software, it is necessary to provide clear abstractions. We present such abstractions in the form of a layered protocol architecture that describes the necessary interfaces. Beyond technical challenges for Horizontal Integration, this paper also addresses network economic considerations since the various entities owning and operating sensors and actuators need suitable economic motivation to participate in such an approach. We believe that this work provides a conceptual foundation for future, scalable IoT solutions.

the cyber physical marketplace a framework for large scale Horizontal Integration in distributed cyber physical systems
2013Co-Authors: Tilman Wolf, Michael Zink, Anna NagurneyAbstract:Cyber-Physical Systems (CPS) represent the technical foundation to solve some of the most important societal and environmental problems. Traditionally, CPS have been considered tightly integrated solutions that are aimed at specific application domains. More recently, a broader view of distributed cyber-physical systems (DCPS) has emerged, where interacting components are more loosely coupled and real-time constraints and safety concerns are less dominating. To develop a common infrastructure for a large-scale DCPS, it is critical to develop a framework that allows for Horizontal Integration of CPS components. In this paper, we discuss the vision, requirements, and design of such a framework. We present several specific technical challenges that need to be addressed in this context as well as potential solution approaches. We also provide examples to illustrate how our framework can lead to innovative new uses that can have meaningful impact on practical problems.

multi product supply chain Horizontal network Integration models theory and computational results
2010Co-Authors: Anna Nagurney, Trisha Woolley, Qiang QiangAbstract:In this paper, we develop multi-product supply chain network models with explicit capacities, before and after their Horizontal Integration. In addition, we propose a measure, which allows one to quantify and assess, from a supply chain network perspective, the synergy benefits associated with the Integration of multi-product firms through mergers/acquisitions. We utilize a system-optimization perspective for the model development and provide the variational inequality formulations, which are then utilized to propose a computational procedure which fully exploits the underlying network structure. We illustrate the theoretical and computational framework with numerical examples. This paper is a contribution to the literatures of supply chain Integration and mergers and acquisitions.

vertical and Horizontal Integration of multi omics data with miodin
2019Co-Authors: Benjamin UlfenborgAbstract:Studies on multiple modalities of omics data such as transcriptomics, genomics and proteomics are growing in popularity, since they allow us to investigate complex mechanisms across molecular layers. It is widely recognized that integrative omics analysis holds the promise to unlock novel and actionable biological insights into health and disease. Integration of multi-omics data remains challenging, however, and requires combination of several software tools and extensive technical expertise to account for the properties of heterogeneous data. This paper presents the miodin R package, which provides a streamlined workflow-based syntax for multi-omics data analysis. The package allows users to perform analysis of omics data either across experiments on the same samples (vertical Integration), or across studies on the same variables (Horizontal Integration). Workflows have been designed to promote transparent data analysis and reduce the technical expertise required to perform low-level data import and processing. The miodin package is implemented in R and is freely available for use and extension under the GPL-3 license. Package source, reference documentation and user manual are available at https://gitlab.com/algoromics/miodin.

how Horizontal Integration affects transaction costs of rural collective construction land market an empirical analysis in nanhai district guangdong province china
2019Co-Authors: Xiangxiang Xie, Anlu Zhang, Lanjiao Wen, Peng BinAbstract:Abstract High transaction costs caused by dispersed and fragmented tracts, insecure tenure and incomplete information in rural land market has become a common issue in the transition economies. Horizontal Integration may economize on transaction costs but aggrandize governance inputs. Therefore trade-off between Integration and governance is one of the biggest challenges in land commercialization and rural restructuring worldwide. Resorting to a field survey in Nanhai District, Guangdong Province, this work estimates how the transaction costs of rural collective construction land are influenced by the Horizontal Integration degree and the level of self-organization governance of collectives. Four Tobit models are constructed based on the scale of collectives and the results show that: (1) There is an almost U-shaped relationship between the Horizontal Integration degree of the collectives and the transaction costs. The Horizontal Integration among shareholders can not only centralize the fragmented land assets from individual farmers and reduce the transaction costs of rural construction land, but also result in organization costs. The transaction costs are not decreasing as the Horizontal Integration increases until the transaction costs saved are equal to resultant organization costs. (2) The more collective leaders, the higher organization costs and the more opportunism behaviors, which will give rise to the transaction costs. This suggests that the Chinese authorities should strengthen the ongoing efforts to reduce the transaction costs of market and improve the efficiency through a more transparent and accessible market and optimal scale of Horizontal Integration of the collective. Our work sheds some light on the mechanisms at play in the reform and innovation of rural grass-root governance and it contributes to a better understanding of land-based shareholding cooperation system and nature of ongoing rural construction land market in China and transitional economies.
