Abstract Infrastructure systems must change to match the growing complexity of the environments they operate in. Yet the models of governance and the core technologies they rely on are structured around models of relative long-term stability that appear increasingly insufficient and even problematic. As the environments in which infrastructure function become more complex, infrastructure systems must adapt to develop a repertoire of responses sufficient to respond to the increasing variety of conditions and challenges. Whereas in the past infrastructure leadership and system design has emphasized organization strategies that primarily focus on exploitation (e.g., efficiency and production, amenable to conditions of stability), in the future they must create space for exploration, the innovation of what the organization is and does. They will need to create the abilities to maintain themselves in the face of growing complexity by creating the knowledge, processes, and technologies necessary to engage environment complexity. We refer to this capacity as infrastructure autopoiesis. In doing so infrastructure organizations should focus on four key tenets. First, a shift to sustained adaptation—perpetual change in the face of destabilizing conditions often marked by uncertainty—and away from rigid processes and technologies is necessary. Second, infrastructure organizations should pursue restructuring their bureaucracies to distribute more resources and decisionmaking capacity horizontally, across the organization’s hierarchy. Third, they should build capacity for horizon scanning, the process of systematically searching the environment for opportunities and threats. Fourth, they should emphasize loose fit design, the flexibility of assets to pivot function as the environment changes. The inability to engage with complexity can be expected to result in a decoupling between what our infrastructure systems can do and what we need them to do, and autopoietic capabilities may help close this gap by creating the conditions for a sufficient repertoire to emerge.

Purpose – The purpose of this article is to define a framework for projecting future leading-edge alpha societies based on the principle of requisite variety. Alpha societies are advanced as a platform for creating future forms of work and workforce preparation premised on continuous creativity, invention, design and innovation. Design/methodology/approach – The principle of requisite variety is presented as the basis for a structured schema that incorporates trends and developments in anticipatory behaviors, systems thinking, creativity, design and innovation to produce a strategy for continuous leading-edge learning and performance. Findings – Growing global hypercompetition requires real-time ability to create and deliver world-class ideas and value-adding products and services in the shortest possible timeframes. This challenge requires societies, enterprises and individuals that are capable of continuously expanding and expressing their internal variety and complexity while rapidly decreasing the gaps between learning and doing. Research limitations/implications – The principle of requisite variety has been well known to cybernetics and systems communities since 1956. However, literature linking the principle of requisite variety to the future of learning and work is not well developed. Practical implications – This article establishes requisite variety generation as a valuable resource for twenty-first century societies and economies engaged in producing leading-edge outcomes. Social implications – The requisite variety framework developed in this article is intended to enhance the ability of leading-edge societies to continuously leapfrog existing educational, social and economic trajectories. Originality/value – The author defines the future of education and work in terms of enhancing individual, enterprise and societal abilities to absorb, generate and exploit variety, complexity and ambiguity.

This paper suggests cybernetic strategies for improving organizational control and information systems. The suggestions are based on the postulates of Beer’s cybernetic Viable System Model (VSM). The VSM was based on the way the human body’s neural control system successfully manages the high degree of complexity it regularly faces. The model identifies five linked control subsystems and specifies propositions concerning their information-processing behavior. The five systems are responsible for the following key tasks: policy development, environmental matters, internal control, coordination of basic units, and the basic work of the system. The information-handling propositions focus on providing requisite capacities in (a) the communication channels linking the five control systems, (b) the transducers that carry information across system boundaries, and (c) the complexity of linked pairs of control systems. The suggested management strategies focus on designing organizations to satisfy the task differentiation, communication channel capacity, transducer capacity, and requisite complexity postulates of the model.

This study examines how leaders enable their organisations to adapt and succeed in complex environments. Through the joint lenses of complexity theory and the cognition and social neuroscience of leadership it focuses on how leadership directly influences the creation and ongoing function of an adaptive organisation. The study includes the comparison of four leaders through embedded case studies as an abductive approach to initial theory building, and the follow up of two of them as a comparative method of analysis, and it generates a substantive theory of leadership cognition called emergent logic. This leadership approach is especially relevant to leading complex human systems in emergent environments, the scenario for the majority of organisations in the present day. This thesis addresses two questions: How do leaders of adaptive organisations think? And what do leaders of adaptive organisations do? Among the major findings the study reveals that a critical success factor is the leader’s capacity to create and guide a complex human system by establishing and maintaining a shared mental model of its collective purpose, guided by deeply held and articulated values. The cognitive constructs of complexity and emergent logic have a direct and indirect effect on individuals and the organisation, and facilitate the creation of an adaptive operational culture and organisational mind, and the complementary enabling structures that allow for ongoing evolution through emergence, transformation and diffusion as required. Thus the organisation and its people can progressively build more complex emergent mental models and solutions in the face of increasingly common unpredictable situations, leading to the capability for organisational adaption and evolution over time. In contributing to the theory of creating and leading adaptive organisations, supported by empirical research, this study has improved our understanding of the effect of the leader’s cognitive capacity on organisational adaptability and the level of entanglement; revealed the links between the creation of adaptive organisational structures and their culture; examined the growth of individual and collective capability to manage the increasing complexity and emergence created by successful adaption and evolution; identified the common elements of various types of complex systems that are relevant to adaptive change; presented a model of emergent logic and described the empirical use of that model over time.

Megaprojects are intricate solutions shaped over many years to fit specific contexts and market needs. This chapter focuses on megaprojects as games of innovation in which sponsors, experts, and potentially opposing stakeholders interact to shape opportunities into projects and to design and deliver these projects. Each project calls for multiple innovative choices over time in the face of foreseeable and emerging issues, in a design tradespace that reflects multiple dimensions of value. Keeping these trade-offs alive over the life of the project requires that sponsors and experts master the inherent complexity of megaprojects and develop architectures and processes that deliver with requisite complexity.

In this chapter, the author proposes an enterprise complexity model (ECM), which is visualized as a methodology to achieve the distributed governance of an ecology of evolving enterprises. Governance is understood as guiding the enterprises self-organization towards policies creating, regulating, and producing products and services for society. Self-organization is grounded in the communications and interactions of stakeholders. The purpose of an ECM model is not institutional development but guiding, enabling and facilitating interactions of all kinds with the support of current and disruptive technologies to increase society's requisite variety to deal with social, ecological, and economic challenges. An enabling context helps the branching of the enterprises' creativity into all kinds of innovations, forms of coordination, and operational alignment of their interests. Quality of life, fairness, and social justice are the values driving this ecology of enterprises towards a deeper and wider appreciation of issues of social concern.

Claus Offe notes that, since every mode of state policy-making is prone to failure, either a stable state is impossible or can only exist where the state can flexibly shift modes of policy-making as the failures of prevailing policy-making threaten its rationality and legitimacy. This depends on the strategic capacities to sustain exchange, negotiation, hierarchy, or solidarity as well as the specific nature of the coordination problems. Whilst increasing functional differentiation makes hierarchical coordination increasingly problematic, the structural and strategic conditions for effective governance may not be developed enough to outperform continued reliance on hierarchy or neo-liberal preferences for marketized solutions. We must examine the self-reflexive, self-diagnosing, and self-modifying capacities of governing agents and their institutional capacities to redesign themselves in response to failures. Effective governance and metagovernance depend on requisite complexity, requisite reflexivity, and requisite irony.

Abstract This chapter examines the necessity of more adequate organizational governance schemes for artificial intelligence (AI) systems and processes. AI and its related industries and technologies are multifaceted, requiring more than the traditional and simple methods of governance. Networked and complex governance models—those mixing several governance schemes to achieve policy goals—offer a solution for intricate issues. Concentrations of power in one agency often fail to adequately offer the requisite regulatory oversight necessary for multifaceted issues like those of artificial intelligence and machine learning systems. The use of traditional governance strategies, such as transparency, does not produce the desired result of a better-informed public and more careful organizations. Multifaceted, complex issues demand equally complex solutions. This chapter, then, considers what a complexity-informed model of governance might look like for AI and ML systems.

The registration of corresponding patient volumes is often a pre-requisite for medical imaging tasks. Accurate alignment, however, usually results in high computational complexity and can hence take a considerable amount of time. This is particularly true with 3-D volume data which adds another dimension to the registration process. One possibility of keeping registration times feasible is to distribute computation among several processors so that it maybe accomplished in parallel. This chapter provides a short survey of parallel registration approaches which have been proposed together with some recent research adopting a blackboard architecture for distributed high performance image and volume registration purposes.

How can systems and cybernetics address the issues arising from an increasingly complex world, that often is beyond our traditional response capabilities? The author argues that to address such complexity we require imaginative propositions and innovative behaviours to see and address the inherently systemic nature of our world, which too often is fragmented by policies driven by non-systemic models. Socially, we live in a world experiencing systemic deficit; our policy responses are often fragmented, but even if they are not, socially designed responses fail to recognise environmental constraints and produce innovative allocations of requisite resources to make them happen. The author argues that conversational spaces, such as those offered by the World Organisation of Systems and Cybernetics [WOSC], and other cybersystemic associations, should help dealing with fragmentation and resources allocation; he sees these conversations as necessary contributions to redress our systemic deficit. Systemic thinking should help in visualising social situations as wholes, thus reducing the chances of dysfunctional fragmentation and cybernetics should help us understanding processes of dynamic stability in the interactions among and between people, institutions, and organizations. Systemic thinking should give us methodological tools; cybernetics should give us communication tools to manage the complexity of situations from the local to the global. The paper discusses complexity management strategies, emphasising the need to deal operationally with this complexity rather than cognitively; operational complexity is orders of magnitude larger than cognitive complexity. The paper ends up with an illustration of these complexity management strategies in higher education.

In recent years, the idea of integration of sustainability into project management has been put forth, which requires a more comprehensive and holistic approach to project management. Integration of sustainability increases the complexity of project management. Therefore, project management organizations require a framework capable of opening up the traditional organization of the project business and providing competitive advantages. This study argues that the open innovation model presents the requisite capability to approach this issue. This research, through a structured review of the literature and an overview of the open innovation and project management knowledge areas, explains how open innovation can provide a fruitful contribution to the integration of sustainable development into project portfolio management and why it should be favoured. The findings show that open innovation can facilitate the environmental, social and economic sustainability of projects, while rendering the project organization more agile.

CFD simulation of vehicle under-hood and under-body poses several challenges. Specifically, the complexity of the geometry involved makes the use of traditional mesh generation approaches, based on the boundary-to-interior methodology, impractical and time consuming. The current work presents the use of an interior-to-boundary method wherein the need for creating a ‘water-tight’ surface mesh is not a pre-requisite for volume mesh generation. The application of the new method is demonstrated for an actual passenger vehicle under-hood model with nearly a hundred components. Coupled radiation/convection simulations are performed to obtain the complete airflow and thermal map of the engine compartment. Results are validated with test data. The new method results in significant gains in efficiency over traditional approaches allowing the simulation tool to be used effectively in the vehicle development process.

Abstract Additive manufacturing (AM) offers access to the entire volume of a printed artifact during the build operation. This makes it possible to embedding foreign components (e.g. sensors, motors, actuators) into AM parts, thus enabling multifunctional products directly from the build tray. However, the process of designing for embedding currently requires extensive designer expertise in AM. Current methods rely on a designer to select an orientation for the embedded component and design a cavity such that the component can be successfully embedded without compromising the print quality of the final part. For irregular geometries, additional design knowledge is required to prepare a shape converter: a secondary piece to ensure a flush deposition surface on top of the embedded component. This research aims to develop a tool to automate these different design decisions for in-situ embedding, thus reducing the need for expert design knowledge. A three-stage process is proposed to 1) find the optimum orientation based on cavity volume and cross-section area, 2) create the necessary cavity geometry to successfully insert the component, and 3) perform a Boolean operation to create the digital design for any requisite shape converter. Performance of the tool is demonstrated with four test cases with varying levels of geometric complexity. These test cases show that the proposed process successfully handles arbitrary embedded geometries, though several limitations are noted for future work.

Formation water saturation is a critical target property for any comprehensive well log analysis program. Most techniques for computing saturation depend heavily on an analyst’s ability to accurately model resistivity measurements for the effects of formation water resistivity and rock texture. However, the pre-requisite knowledge of formation water properties, particularly salinity, is often either unknown, varying with depth or lateral extent, or is difficult to derive from traditional methods. A high degree of variability may be present due to fluid migration from production, water injection, or various geological mechanisms. In unconventional reservoirs, the complexity of the rocks and pore structure further complicates traditional interpretation of the available well logs. These factors introduce significant uncertainties in the computed fluid saturations and therefore can substantially affect final reserves estimates. A novel technique in geochemical spectroscopy has recently been introduced to distinguish the chlorine signals of the formation and borehole. The new, quantitative measurement of formation chlorine enables a direct calculation of bulk water volume for a given formation water salinity. When integrated into a multi-physics log analysis workflow, the chlorine-derived water volume can provide critical information on fluid saturations, hydrocarbon-in-place, and producibility indicators. This additional information is especially useful for characterizing challenging and complex unconventional reservoirs. We present the new technique through several full petrophysical evaluation case studies in organic shale formations across the U.S., including the Midland, Delaware, Marcellus, and DJ basins. We solve for formation-specific water salinity and bulk water volume through an optimization that combines chlorine concentration with resistivity and dielectric measurements. These outputs are integrated into comprehensive petrophysical evaluations, leveraging a suite of advanced well log measurements to compute final fluid and rock properties and volumetrics. The evaluations include geochemical mineralogy logs, 2D NMR analyses, dielectric dispersion analyses, basic log measurements, and multi-mineral models. The results underscore the utility of the new spectroscopy chlorine log to reduce petrophysical model uncertainties in an integrated workflow. While this workflow has been demonstrated here in several U.S. organic shale case studies, the fundamental challenges it addresses will make it a valuable solution for a range of unconventional reservoirs globally.

Computer simulation models play a vital role in the assessment of a ship’s autopilot design. A well-tuned autopilot will contribute to reducing rudder activity, thereby minimizing wear on the actuation plant and also generally reducing fuel consumption. The equations that describe the ship motion dynamics contain a large number of hydrodynamic coefficients that must be calculated as accurately as possible to justify the use of a simulation model and its relevance to predicting the ship manoeuvring characteristics. Proper prediction of the ship performance is an essential pre-requisite in the process of tuning the autopilot. The hydrodynamic coefficients can be calculated by using theoretical methods or by carrying out experiments on the actual ship or on a scaled model of the ship. System Identification (SI) is an experiment-based approach and in this paper the authors present an algorithm that can estimate the coefficients with great accuracy. These coefficients can classically be obtained in a towing tank using a captive model, and with a planar motion mechanism and a rotating arm. Generally, these systems are costly and entail expensive trials programs, and SI methods have been developed in an effort to obviate some of those problems and limitations. They typically process ship manoeuvring data obtained from a free-running scaled model or full-scale trials. While similar to a surface ship, the motion dynamics of a submarine introduce additional challenges for SI methods. This is because the submarine manoeuvres in “three dimensions”, which adds complexity and more hydrodynamic coefficients to the equations. The standard submarine simulation model, also referred to as the Gertler and Hagen equations, incorporates over 120 coefficients. To calculated these coefficients, the SI algorithm uses a Square-Root Unscented Kalman filter (SR-UKF). One of its appealing features is that it calculates all the coefficients by processing data from a single submarine manoeuvre that has a repeating sinusoidal pattern in both depth and course. The manoeuvre can be performed in a towing tank by a free-running scaled model of the submarine, or it can be performed at sea on the full-scale submarine as part of the sea trials schedule.

A requisitely holistic information support can help us improve our business operation, but such information is hard to attain and even harder to attain in virtual organizations presenting a specific, more fluid form of business systems. Important difficulties include complexity and complicatedness, time (real and future, and their difference from the past), information requirements (realistic definition of them and meeting them), and related methodological problems. Anticipation capability may help business systems develop into anticipatory ones and develop their prevailing thinking style into the anticipatory system thinking (aimed at requisitely holistic mastering of the potential future, even a virtual one).

With the growth of the Information Technology market (IT), a strong demand for different ways to develop software quality has arisen, and therefore a demand for qualified professionals. To enable these professionals, an effective teaching model is necessary for the development and improvement of skills and competencies oriented to the development of real projects with similar complexity to those found in the labor market. For this, the method of teaching Problem based Learning (PBL) has been applied in different market areas. The PBL use problems designed to initiate, motivate and focus in the acquisition of knowledge through practice, and encourage the development of skills, needed in a professional context. This study aims to develop a tool, called ReqStore, to help the teacher while using the PBL methodology with a project requirements repository. As a result of this work, we carried out an experiment in a class of Programming Fundamentals of discipline to validate tthe effectiveness of tool with use of PBL methodology.

Segurança de TI se tornou nos últimos anos uma grande preocupação para empresas em geral. Entretanto, não é possível atingir níveis satisfatórios de segurança sem que estes venham acompanhados tanto de grandes investimentos para adquirir ferramentas que satisfaçam os requisitos de segurança quanto de procedimentos, em geral, complexos para instalar e manter a infraestrutura protegida. A comunidade científica propôs, no passado recente, modelos e técnicas para medir a complexidade de procedimentos de configuração de TI. No entanto, apesar do papel central da segurança neste contexto, ela não foi objeto de investigação até então. Para abordar este problema, neste trabalho aplica-se um modelo de complexidade proposto na literatura para mensurar o impacto de segurança na complexidade de procedimentos de TI. A proposta deste trabalho foi materializada por meio da implementação de uma ferramenta para análise de complexidade denominada Security Complexity Analyzer (SCA), que foi utilizada para avaliar a complexidade de cenários reais de segurança.

This rapid review found an absence of literature focused specifically on measuring the impact of PFM and governance systems in countries that have transitioned from aid, by moving up the income ladder. However, there are a few academic publications and a limited number of studies by multilateral, such as the World Bank, that examine the role of PFM and governance systems in countries that are transitioning or have moved away from aid. However, the importance of public financial management (PFM) and governance systems in development is well established and seen as a pre-requisite for economic growth. To effectively transition from aid, most low-income countries (LICs) need to upgrade their PFM and governance systems to meet the different scale, resources, accountability mechanisms, and capacity-building requirements of a middle-income country (MIC). The absence of the above empirical evidence may be due to the complexity of measuring the impact of PFM reforms as the results are non-linear, difficult to isolate from other policies to establish causality, and manifest in a longer time frame. However, through comparative country studies, the consequences of deficient PFM and governance have been well documented. So impaired budgetary planning, implementation, and reporting, limited fiscal transparency, weak accountability mechanisms, resource leakage, and inefficient service delivery are well recognised as detrimental to economic growth and development. The literature on transitioning countries focuses predominantly on the impact of aid withdrawal on the social sector, where comparative qualitative data is easier to obtain and the effects are usually more immediate, visible, and may even extend to global health outcomes, such as in AIDS prevention programmes. Thus, tracking the progress of donor-assisted social sector programmes is relatively easier than for PFM and governance reforms. The literature is more abundant on the overall lessons of transitions from aid both for country governments and donors. The key lessons underscore the importance of PFM and governance systems and mechanisms to a successful transition up the income ladder: Planning for transition should be strategic, detailed and specifically geared to mitigate against risks, explicitly assessing the best mix of finance options to mitigate the impact of aid reduction/withdrawal on national budgets. The plan must be led by a working group or ministry and have timelines and milestones; Where PFM and governance is weak transition preparation should include strengthening PFM especially economic and fiscal legislation, administration, and implementation; Stakeholders such as donor partners (DPs) and NGOs should participate in the planning process with clear, open, and ongoing communication channels; Political and economic assessments in the planning and mid-term phases as well as long-term monitoring and evaluation should be instituted; Build financial, technical, and management capacity throughout the plan implementation This helpdesk report draws on academic, policy, and grey sources from the previous seven years rather than the usual K4D five-year window, to account for the two-year disruption of COVID-19. As cross-country studies on PFM and governance are scarce, a few older studies are also referenced to ensure a comprehensive response to the query. The report focuses on low-income countries transitioning from aid due to a change in status to lower-middle-income countries.
