Understanding Collaboration in the Context of Loosely- and Tightly-Coupled Complex Adaptive SystemsLeduc, Nathaniel January 2018 (has links)
Many of the technological and social systems our society has come to depend on can be classified as complex adaptive systems (CAS). These systems are made of many individual parts that self-organize to respond and adapt to changing outside and inside influences affecting the system and its actors. These CAS can be placed on a spectrum ranging from loosely- to tightly-coupled, depending on the degree of interrelatedness and interdependence between system components. This research has explored how the process of collaboration occurs in both a loosely- and tightly-coupled setting using one exemplar of each system. The loosely-coupled exemplar related to disaster risk reduction in two Canadian communities while the tightly-coupled one involved the implementation of a surgical information management system in a Canadian hospital. A list of core elements of collaboration that should be considered essential to the success of all collaborative endeavours was developed as a result: Engagement, Communication, Leadership, Role Clarity, Awareness, Time, and Technical Skills and Knowledge. Based on observing how the core elements of collaboration interacted with one another within each of these example systems, two models were created to represent their relationships. A list of considerations that collaborative tool designers should consider was also developed and the implications of these considerations were discussed. As businesses and other organizations increasingly incorporate team-based work models, they will come to depend more heavily on technology-based solutions to support collaboration. By incorporating collaborative technologies that properly support the activity of these teams—based on the specific type of complex adaptive system in which their organization exists—organizations can avoid wasting time and resources developing tools that hinder collaboration.

A System Perspective on Business ModelsJucun Liu (8702721) 17 April 2020 (has links)
The business model concept was first introduced in the early 1990s alongside the boom of the Internet. Although the Internet bubble has burst, the popularity of the business model concept continues to increase. It is being used more and more often by not just people in business management, but also the general population, as people, for example, talk about a successful start-up. Although it has become part of the vernacular today, the business model concept itself is lacking in theoretical roots. Thus, a gap exists regarding the business model concept. Its usefulness in practice has been proven in numerous business cases, yet academia remains divided on the definition and appropriate means to use the concept. A thorough literature review reveals that the concept of a business model has been framed in various ways, ranging from the strategic logic of a company to the activities a company performs. This misalignment creates barriers for the advancement of this body of knowledge in both research and practice. Researchers have thus called for a clearer and more operational definition of the concept.<br> With this goal in mind, this qualitative study sought to advance business model understanding by proposing a business model conceptualization that: <br> 1) Is robust in its theoretical roots and informs the critical characteristics of a business model, <br> 2) Highlights potential means to resolve the debate over the definition of a business model through examination of its broad range of conceptualizations and uses, and,<br> 3) Guides business model design through a robust exploration of design options for users interested in business model development. <br> To achieve this goal, a three-stream study was conducted.<br> The first stream focused on creating a business model construct that is rooted in advanced system theory and on proposing a related business model framework. This objective was achieved through a combination of scholarship of integration and thematic analysis. A resilient complex adaptive system (RCAS) perspective was taken to proactively construct a business model conceptualization. To fully understand an RCAS, a literature review was carried out on the notion of systems. Theories from general system theory (GST) to an RCAS were examined to form a full understanding of these foundational concepts. The resulting construct was employed as the underlying structure of a business model framework. To create a set of functions that a business model should include, an extensive literature review was conducted on 150 business model research articles. Thematic analysis was employed to analyze words and phrases used by authors to describe the critical components of a business model, and then aggregate these views into a set of mutually supportive functions that represent the essence of a business model. Eight functions, termed “elemental functions”, centered on value were defined. These elemental functions are able to capture all components identified in the studied literature and collectively display required RCAS characteristics. This RCAS business model framework lays the foundation for a unified landscape of business model conceptualization and acts as a potential universal language in this body of knowledge. The developed framework also serves as the basis for the subsequent lines of work detailed below, and grounds both further research and application.<br> The second stream is based on the RCAS framework and draws on its ability to facilitate abstraction. The work stream focuses on outlining a knowledge space for business models utilizing three variables that are closely tied to abstraction in the business model context, namely: elemental functions, purposes, and levels of abstraction. These variables were identified as critical factors influencing business model variation from both a literature perspective and observations. A thematic analysis was conducted on the same 150 articles as in the first stream to extract the potential states of these variables. Eleven purposes and five levels of abstraction were identified; and these two variables act as the axes of the knowledge space. Elemental functions were incorporated in the knowledge space to illustrate the frequency with which each elemental function is used for specific purposes and specific levels of abstraction. This knowledge space, herein termed the business model knowledge map, can be used to position existing work and identify future opportunities for research. The 150 articles were positioned in this space to outline a grander picture of the business model concept. It highlights that previous authors in the business model area have worked on abstractions of the same concept. This stream is another step towards a universal landscape of business model conceptualization that could help unify previously diverse views of business models.<br> The last work stream contributes to the design of business models – one of the key purposes for which business model constructs are employed as highlighted in the knowledge map described above. Specifically, this work stream puts forward a system-inspired business model design method. Building directly on the RCAS framework, this stream employs combinatorial design thinking from engineering and design to create a design method. One of the most critical aspects of this design method is its emphasis on creating a complete, to the extent possible, set of design options for each elemental function that composes a business model. To achieve this, an extensive review of over 200 company annual reports was conducted to generate design options for each elemental function. This design method focuses on raising awareness of one’s design options thereby enhancing the potential for business model innovation.<br> Collectively, this study advances the business model body of knowledge in both research and practice. The study is unique in its proactive employment of the RCAS construct to define a business model, its focus on abstraction to form a theoretically robust and potentially universal landscape for knowledge and research on business models, and its proposition of a structured approach to complete business model design. It is hoped that the developments outlined herein help pave a path to a more unified view of business model concepts that can foster connections between the work of researchers who employ business model constructs and further advance the state of knowledge in this arena.<br><br>

A networked multi-agent combat model : emergence explainedYang, Ang, Information Technology & Electrical Engineering, Australian Defence Force Academy, UNSW January 2007 (has links)
Simulation has been used to model combat for a long time. Recently, it has been accepted that combat is a complex adaptive system (CAS). Multi-agent systems (MAS) are also considered as a powerful modelling and development environment to simulate combat. Agent-based distillations (ABD) - proposed by the US Marine Corp - are a type of MAS used mainly by the military for exploring large scenario spaces. ABDs that facilitated the analysis and understanding of combat include: ISAAC, EINSTein, MANA, CROCADILE and BactoWars. With new concepts such as networked forces, previous ABDs can implicitly simulate a networked force. However, the architectures of these systems limit the potential advantages gained from the use of networks. In this thesis, a novel network centric multi-agent architecture (NCMAA) is pro-posed, based purely on network theory and CAS. In NCMAA, each relationship and interaction is modelled as a network, with the entities or agents as the nodes. NCMAA offers the following advantages: 1. An explicit model of interactions/relationships: it facilitates the analysis of the role of interactions/relationships in simulations; 2. A mechanism to capture the interaction or influence between networks; 3. A formal real-time reasoning framework at the network level in ABDs: it interprets the emergent behaviours online. For a long time, it has been believed that it is hard in CAS to reason about emerging phenomena. In this thesis, I show that despite being almost impossible to reason about the behaviour of the system by looking at the components alone because of high nonlinearity, it is possible to reason about emerging phenomena by looking at the network level. This is undertaken through analysing network dynamics, where I provide an English-like reasoning log to explain the simulation. Two implementations of a new land-combat system called the Warfare Intelligent System for Dynamic Optimization of Missions (WISDOM) are presented. WISDOM-I is built based on the same principles as those in existing ABDs while WISDOM-II is built based on NCMAA. The unique features of WISDOM-II include: 1. A real-time network analysis toolbox: it captures patterns while interaction is evolving during the simulation; 2. Flexible C3 (command, control and communication) models; I 3. Integration of tactics with strategies: the tactical decisions are guided by the strategic planning; 4. A model of recovery: it allows users to study the role of recovery capability and resources; 5. Real-time visualization of all possible information: it allows users to intervene during the simulation to steer it differently in human-in-the-loop simulations. A comparison between the fitness landscapes of WISDOM-I and II reveals similarities and differences, which emphasise the importance and role of the networked architecture and the addition of strategic planning. Lastly but not least, WISDOM-II is used in an experiment with two setups, with and without strategic planning in different urban terrains. When the strategic planning was removed, conclusions were similar to traditional ABDs but were very different when the system ran with strategic planning. As such, I show that results obtained from traditional ABDs - where rational group planning is not considered - can be misleading. Finally, the thesis tests and demonstrates the role of communication in urban ter-rains. As future warfighting concepts tend to focus on asymmetric warfare in urban environments, it was vital to test the role of networked forces in these environments. I demonstrate that there is a phase transition in a number of situations where highly dense urban terrains may lead to similar outcomes as open terrains, while medium to light dense urban terrains have different dynamics

人工股票市場的Agent-Based計算建模 / On Agent-Based Computational Modeling of Artificial Stock Markets廖崇智, Liao, Chung-Chih Unknown Date (has links)
我們把經濟體視為一個複雜適應系統(complex adaptive system), 強調系統中異質性(heterogeneous)agent的學習適應行為與agent之間的互動性交互作用, 此時主流經濟學裡的分析架構, 如:代表性個人模型(represesentive agent model)、理性預期(rational expectation)、固定點均衡分析(fixed-point equilibrium analysis)等將不再適用, 取而代之的是演化經濟學(evolutionary economics)的研究典範, 這樣的研究架構下, 並沒有適當的數學分析工具可資運用, 因此我們改以agent-based建模(agent-based modelng)的社會模擬(social simulation)來建構一個人工的經濟體(artificial economy), 以此為主要研究方法, 這就是agent-based計算經濟學(agent-based computational economics)或稱人工經濟生命(artificial economic life)。
本文中以股票市場為主要的研究課題, 我們以遺傳規劃(genetic programming)的人工智慧(artificial intelligence)方法來模擬股市中有限理性(bounded rational)異質交易者的交易策略學習行為, 建構出一個人工股票市場(artificial stock market), 在這樣的架構下, 我們成功地產生出類似真實股票市場的股價時間序列特性, 我們同時也檢定了人工股票市場中價量的因果關係, 說明了在沒有外生因素之下, 人工股票市場的複雜系統可自發地產生出雙向的價量因果關係, 進一步地, 我們研究下層agent(交易者)行為與上層股價時間序列行為的關聯性, 我們也發現個體的行為並不能直接加總或推論出複雜適應系統的總體行為, 這就是突現性質(emergent property)的發生, 最後, 本文描述了agent-based計算經濟學研究架構的優勢與缺點, 再附帶介紹一個用以進行agent-based建模相關研究的軟體程式庫-SWARM。

考量消費者行為與供應商價格競爭之零售商價格競爭模式之研究 / A Study on Pricing Competition Model of Retailer with Learning Behavior of Consumer and Competition of Supplier鄧廣豐, Deng, Guang Feng Unknown Date (has links)
在複雜動態競爭市場中,生產者的價格競爭行為一直是一個研究的重點,相較於生產者動態價格競爭,零售商的價格競爭行為鮮少被探討,因此本研究針對零售商價格競爭行為進行研究。針對零售商之間的價格競爭行為,除了考量零售商與對手零售商的價格互動,不可忽略的是上游供應商的競爭互動與下游消費者的學習行為在市場中與零售商端互動下錯綜複雜的動態影響,緣此,本研究以零售商端的角度,想了解供應商競爭與消費者學習行為對零售商競爭的影響,再以單一零售商角度,分析各情況下所應對的價格調整策略。
本研究將零售商、供應商及消費者互動形成之競爭市場視為一個複雜適應性系統(Complex Adaptive System ,簡稱CAS),應用代理人基塑模與模擬(Agent-based Modeling and Simulation,簡稱ABMS)方式建構考量供應商競爭與消費者學習行為之零售商價格競爭模式,將演化賽局理論應用於價格競爭中,探討不同的消費者學習及供應商價格競爭行為如何動態影響零售商價格競爭型態,以及不同價格調整策略之績效表現。
研究結果發現一,市場中消費者呈現不同的學習行為,對零售商競爭將造成不同的衝擊。「貨比三家無學習」型消費者將造成零售商端低價競爭,使其平均價格最低及獲利最低。「自我式學習」型消費者將造成零售商高價合作,使其平均價格最高及獲利最高。「群體式學習」型消費者同樣使零售商端偏向高價合作,且其平均價格及獲利相當接近自我式學習市場,雖然兩種學習行為具有近似的平均價格與獲利,「群體式學習」卻會導致零售商價格競爭之型態轉為劇烈,包括獲利領先轉換方式由漸進轉為瀑布,領先方式從勢均力敵轉為大幅領先,領先互換的頻率由低轉為高。另外,消費者購買決策之理性程度對零售商端競爭形態有影響,不論在何種供應商行為下,高理性購買決策在群體式學習下將導致零售商端價格競爭較激烈,在自我式學習下卻導致零售商端競爭行為較緩和。
研究發現二,市場中供應商的價格競爭行為會對零售商端的價格、獲利與競爭型態造成衝擊。供應商呈現價格競爭行為下,在「貨比三家無學習」之消費者行為市場中,將減緩零售商價格競爭,使零售商端之平均價格及獲利提高。在「自我」與「群體式」學習消費者市場中,將增強零售商價格競爭強度,使零售商端之平均價格及獲利降低。
研究發現三,不同的競爭市場中,零售商之最佳價格調整策略也將不同。基本上在供應商無競爭行為下,無論消費者呈現何種行為,零售商採取開放式價格調整策略具有明顯優勢。在供應商呈現競爭行為下,開放式價格調整策略在「無學習」及「群體式學習高理性程度」行為市場仍為優勝策略,在「自我式學習」及「群體式學習低理性程度」下,保守型價格調整策略則表現較佳。
在實務意涵上,若零售商可使消費者行為偏向自我或群體式學習,並穩定供應商價格競爭下,整體而言零售商端競爭可獲得最高的獲利,若當此刻競爭零售商採取保守型價格策略,而本身採取開放式價格調整策略,則獲利最大。然而面臨群體式學習消費者,由於競爭強度的增加,需留意市場動態,須隨時靈活調整本身價格策略,避免因價格策略的僵化,而成為虧損之零售商。 / The pricing competitive model traditionally assumes that consumers will buy from the firm selling the homogeneous product at the lowest price, thus discarding any possibility of learning behavior on the demand side. But if, as in real competition, consumers learn adaptively and competition is a dynamic process, then some attention should be paid to consumers' behavior.
In a multiple supplier – multiple retailer supply chain, multiple price competitive forces interact to influence firm price decisions. These forces include: (1) the supplier level competition each supplier faces from others producing the same product, (2) the retailer level competition among the retailers selling the same set of goods, and (3) the vertical interaction competition between the retailer and supplier.
We are interest in these questions: How does the consumer learning behavior affect the retailer pricing competitive model? How does the competition of supplier affect the retailer pricing competitive model? What is the optimal adaptive pricing strategy for retailer performance in such competitive market including retailers, suppliers and consumers.
Therefore, this research study a version of the pricing competitive (Bertrand) model in which consumer exhibit dynamic adaptive learning behavior when deciding from what retailers they will buy. And we consider to join the supplier competitive pricing behavior into the retailer pricing competitive model and formulate their interaction as evolutional game and to analyze the competition of supplier effect and its impact on the pricing competition of retailers.
This research uses a complex adaptive system perspective to construct a retailer pricing competitive model which considers both competitive supplier and learning consumer behavior. Using agent-based modeling and simulation (ABMS) to construct the competitive market include retailers, suppliers and consumers, and use the fuzzy logic, genetic algorithms to model the pricing decision and learning behavior of retailers and suppliers, and use reinforcement learning and swarm algorithms to model consumers’ learning behavior.
The simulation results demonstrate that: The retailer level obtains the highest profit when the consumer behavior following reinforcement learning. When the consumer behavior displays swarm learning, the retailer level also obtains high profit near the highest profit. However swarm learning increases the competitive intensity on the retailer level. The competitive supplier increases the competitive intensity and decrease profit on the retailer level when the consumer behavior displays reinforcement learning and swarm learning.
The performance of retailer following a closed adaptive pricing strategy (high exploitation low exploration) exceeds that of retailer following an open adaptive pricing strategy (low exploitation high exploration) when the consumer behavior displays reinforcement learning and supplier display competitive behavior. However when the consumer behavior displays swarm learning and supplier display competitive behavior, the performance of retailer following an open adaptive pricing strategy exceeds that of retailer following a closed adaptive pricing strategy.
The proposed pricing competitive model with adaptive learning of consumer behavior and competition of supplier can help retailers to analyze pricing strategy and further discovery and design the more optimal pricing strategy.

Strategic intent and the management of infrastructure systemsBlom, Carron Margaret January 2017 (has links)
Infrastructure is presenting significant national and global challenges. Whilst often seen as performing well, infrastructure tends to do so against only limited terms of reference and short-term objectives. Given that the world is facing a new infrastructure bill of ~£40T, improving the benefits delivered by existing infrastructure is vital (Dobbs et al., 2013). This thesis investigates strategic intent and the management of infrastructure systems; how factors such as organisational structure and business practice affect outcomes and the ways in which those systems — not projects — are managed. To date, performance has largely been approached from the perspective of project investment and/or delivery, or the assessment of latent failures arising from specific shocks or disruptive events (e.g. natural disaster, infrastructure failures, climate change). By contrast, the delivery of system-level services and outcomes across the infrastructure system has been rarely examined. This is where infrastructure forms an enduring system of services, assets, projects, and networks each at different stages of their lifecycle, and affecting one another as they develop, then age. Yet system performance, which also includes societal, organisational, administrative and technical factors, is arguably the level relevant to, and the reality of, day-to-day public infrastructure management. This research firstly investigated industry perceptions in order to test and confirm the problem: the nub of which was the inability to fully deliver appropriate and relevant infrastructure outcomes over the long term. Three detailed studies then explored the reasons for this problem through different lenses; thereby providing an evidence-base for a range of issues that are shared by the wider infrastructure industry. In confirming its hypothesis that “the strategic intent and the day-to-day management of infrastructure systems are often misaligned, with negative consequences for achieving the desired long-term infrastructure system outcomes”, this research has increased our understanding of the ways in which that misalignment occurs, and the consequences that result. It found those consequences were material, and frequently not visible within the sub-system accountable for the delivery of those outcomes. That public infrastructure exists, not in its own right, but to be of benefit to society, is a central theme drawn from the definition of infrastructure itself. This research shows that it is not enough to be focused on technical outcomes. Infrastructure needs to move beyond how society interacts with an asset, to the outcomes that reflect the needs, beliefs, and choices of society as well as its ability to respond to change (aptitude). Although the research has confirmed its hypothesis and three supporting propositions, the research does not purport to offer ‘the solution’. Single solutions do not exist to address the challenges facing a complex adaptive system such as infrastructure. But the research does offer several system-oriented sense-making models at both the detailed and system-level. This includes the probing methodology by way of a diagnostic roadmap. These models aim to assist practitioners in managing the transition of projects, assets, and services into a wider infrastructure system, their potential, and in (re)orienting the organisation to the dynamic nature of the system and its societal imperative.
