A novel identification method for generalized T-S fuzzy systems
2012
Published version of an article from the journal: Mathematical Problems in Engineering. Also available from the publisher:http://dx.doi.org/10.1155/2012/893807 In order to approximate any nonlinear system, not just affine nonlinear systems, generalized T-S fuzzy systems, where the control variables and the state variables, are all premise variables are introduced in the paper. Firstly, fuzzy spaces and rules were determined by using ant colony algorithm. Secondly, the state-space model parameters are identified by using genetic algorithm. The simulation results show the effectiveness of the proposed algorithm
Supply chain coordination under asymmetric information and partial vertical integration
2022
AbstractSupply chain contracting is known to suffer from inefficiency in the presence of asymmetric information. Full vertical integration would eliminate the informational inefficiency but can be strategically undesirable. Yet today’s supply chain partnerships exhibit a certain degree of partial vertical integration via equity ties between the firms. Such governance forms received limited attention in supply chain research. Management literature suggests that partial vertical integration may help the firms to ease contracting problems by aligning their incentives, and thus improve the total surplus. We address this proposition by studying a model of a partially integrated supply chain in w…
A Mathematical Model for Equitable In-country COVID-19 Vaccine Allocation
2022
Given the scarcity of COVID-19 vaccines, equitable (fair) allocation of limited vaccines across the main administrative units of a country (e.g. municipalities) has been an important concern for public health authorities worldwide. In this study, we address the equitable allocation of the COVID-19 vaccines inside countries by developing a novel, evidence-based mathematical model that accounts for multiple priority groups (e.g. elderly, healthcare workers), multiple vaccine types, and regional characteristics (e.g. storage capacities, infection risk levels). Our research contributes to the literature by developing and validating a model that proposes equitable vaccine allocation alternatives…
Exploring the relationship between big data analytics capability and competitive performance : The mediating roles of dynamic and operational capabil…
2020
A central question for information systems (IS) researchers and practitioners is if, and how, big data can help attain a competitive advantage. To address this question, this study draws on the resource-based view, dynamic capabilities view, and on recent literature on big data analytics, and examines the indirect relationship between a firm’s big data analytics capability (BDAC) and competitive performance. The study extends existing research by proposing that BDACs enable firms to generate insight that can help strengthen their dynamic capabilities, which, in turn, positively impact marketing and technological capabilities. To test our proposed research model, we used survey data from 202…
International Vocational Education and Training Research: An Introduction to the Special Issue
2021
The seven articles in this special issue represent a wide range of international comparative and review studies by international research teams from China, Germany, India, Russia, Switzerland and Mexico. The presented projects are part of the national program "Research on the Internationalisation of Vocational Education and Training", funded by the German Federal Ministry of Education and Research (BMBF). An adapted version of Urie Bronfenbrenner���s ecological systems theory forms the conceptual framework of the special issue. The four system levels (micro, meso, exo and macro) are addressed by one article each. The article on the microsystem level focuses on the intended and implemented c…

Mesh complications following prolapse surgery: management and outcome.
2011
Abstract Objective This is a description of complications following prolapse surgery with the use of alloplastic materials, the management and outcome. Study design 54 women have been referred to Mainz, urogynecology referral center due to complications following mesh-augmented prolapse surgery. Results The complaints who lead to the admission are expressed by the new terminology and standardized classification for complications arising directly from the insertion of prostheses and grafts in female pelvic floor surgery [1] . Pain (66.7%), mesh erosion (55.6%) and vaginal discharge (48.1%) were the most frequent complaints. Revision was performed after a median time of 27.2 months post mesh …
Introducing a strategic perspective in lean thinking applications through system dynamics modelling: the dynamic Value Stream Map
2020
PurposeLean Thinking is an operation management discipline which aims to identify, map and analyse the activities forming a process to detect “value waste” and outline the most effective flow of activities to execute in sequence. Process mapping is often developed in lean projects through the use of the Value Stream Map (VSM). Like many other management tools, the VSM adopts a static and non-systemic perspective in the representation of an organizational process. This may result in the implementation of Lean projects inconsistent with the overall organizational long-term strategy, thus leading to dysfunctional performance. In order to overcome this limit, the paper suggests combining VSM wi…
An active inference and epistemic value view of metacognition
2015
Metacognition concerns our monitoring and control of mental operations (knowing what you know). Much thinking about metacognition is liable to fall foul of the classic homunculus problem: Nobody can specify who or what does the "metacognition." We describe how the Active Inference and Epistemic Value (AIEV) model offers an operationalization of epistemic behaviors which can explain two example metacognitive phenomena: Control and monitoring of word learning, and the search for unretrieved information in the feeling of knowing. Curiosity drives a search forward, but it is held in check by considering the utility of what is retrieved from memory.
