This article presents a relational lifecycle model of the emergence of network capability in new ventures. Network capability is defined as a strategic ability learned in interaction with business partners. We focus on the foundational phases and processes of the emergence of this dynamic capability. The lifecycle model comprises three phases that evolve over time in tandem with the level of network engagement. The qualitative study identifies five tipping points or critical changes that move new ventures between the lifecycle phases. Using a sample of new ventures in a longitudinal action research design, the article demonstrates how new ventures emerge in network capability through increasingly complex and multilayered engagement processes with business partners. The relational lifecycle model contributes to the literature on how network capability emerges over time through the dynamics of interaction between business partners as new venture networks evolve and change.

Streszczenie:

The technology lifecycle model is extensively used to study technology evolution and innovation. However, this model was developed for industrial-age material technologies and does not address digital technologies with nonmaterial elements. Therefore, a question emerges as to whether the level of technological materiality is implicated in different dynamics of innovation, as reflected in the technology lifecycle. Digital technologies evolve through discourse that involves interactions among multiple stakeholders that shape the evolutionary trajectory of the technology. Therefore, we set out to examine whether discourse about digital technologies that vary in their level of materiality manifests in different ways throughout these technologies’ lifecycles. To do so, we conducted a study comparing the discourse around 10 digital technologies—five highly material and five highly nonmaterial—at different stages of their technology lifecycles. We identified three characteristics of discourse—volume, volatility, and diversity—and examined them for the 10 digital technologies by analyzing their corresponding Wikipedia articles. Our findings show that the discourse around technologies with different levels of materiality is similar in the initial era of the lifecycle but diverges in the two subsequent eras. In addition, we found that the discourse around highly nonmaterial technologies remains elevated for longer time periods, compared to highly material technologies. Based on these results, we put forth propositions that challenge and extend existing research on the relationships between the technological level of materiality, discourse, and trajectories of technology evolution.

ABSTRACT It remains a major challenge to derive a theory of cloud-scale ($\lesssim100$ pc) star formation and feedback, describing how galaxies convert gas into stars as a function of the galactic environment. Progress has been hampered by a lack of robust empirical constraints on the giant molecular cloud (GMC) lifecycle. We address this problem by systematically applying a new statistical method for measuring the evolutionary timeline of the GMC lifecycle, star formation, and feedback to a sample of nine nearby disc galaxies, observed as part of the PHANGS-ALMA survey. We measure the spatially resolved (∼100 pc) CO-to-H α flux ratio and find a universal de-correlation between molecular gas and young stars on GMC scales, allowing us to quantify the underlying evolutionary timeline. GMC lifetimes are short, typically $10\!-\!30\,{\rm Myr}$, and exhibit environmental variation, between and within galaxies. At kpc-scale molecular gas surface densities $\Sigma _{\rm H_2}\ge 8\,\rm {M_\odot}\,{{\rm pc}}^{-2}$, the GMC lifetime correlates with time-scales for galactic dynamical processes, whereas at $\Sigma _{\rm H_2}\le 8\,\rm {M_\odot}\,{{\rm pc}}^{-2}$ GMCs decouple from galactic dynamics and live for an internal dynamical time-scale. After a long inert phase without massive star formation traced by H α (75–90 per cent of the cloud lifetime), GMCs disperse within just $1\!-\!5\,{\rm Myr}$ once massive stars emerge. The dispersal is most likely due to early stellar feedback, causing GMCs to achieve integrated star formation efficiencies of 4–10 per cent. These results show that galactic star formation is governed by cloud-scale, environmentally dependent, dynamical processes driving rapid evolutionary cycling. GMCs and H ii regions are the fundamental units undergoing these lifecycles, with mean separations of $100\!-\!300\,{{\rm pc}}$ in star-forming discs. Future work should characterize the multiscale physics and mass flows driving these lifecycles.

The system dynamics applied in this research on modeling a tourist destination (area) life cycle (TALC) contributes to understanding its behavior and the way that information feedback governs the use of feedback loops, delays and stocks and flows. On this basis, a system dynamic three-staged TALC model is conceptualized, with the number of visitors V as an indicator of the carrying capacities’ dynamics and the flow function V(t) to determine the TALC stages. In the first supply-dominance stage, the model indicated that arrivals are growing until the point of inflexion. After this point, arrivals continue growing (but with diminishing growth rates), indicating the beginning of the demand-dominance stage, ending up with the saturation point, i.e., the maximum number of visitors. The simulated TALC system dynamics model was then applied to five EU destinations (Living Labs) to explain their development along the observed period (2007–2019). The analysis revealed that all observed Living Labs reached the second lifecycle stage, with one entered as early as in 2015 and another in 2018. Lifecycle stage durations may significantly differ across the destinations, as do the policies used either to prevent stagnation or to restructure the offer to become more sustainable and resilient.

Digital media platforms give users access to enormous amounts of content that they must explore to avoid boredom and satisfy their needs for heterogeneity. Existing strands of work across psychology, marketing, computer science, and music underscore the importance of the lifecycle to understanding exploratory behavior, but they are also often inconsistent with each other. In this study, we examine how users explore online content on Spotify over time, whether by discovering entirely novel music or by refreshing their listening habits from one time frame to the next. We find clear differences between users at different points of their off-platform lifecycles, with younger listeners consistently exploring unknown content less and exploiting known content more. Across their on-platform histories, users also explore in bursts by following seasonal cycles and exploratory phases. We also find that these patterns of exploration do not translate to other notions of heterogeneity like diversity; notably, younger listeners are more diverse in their consumption despite exploring less. Exploration and diversity thus capture different ways in which people find variety, potentially accounting for the inconsistencies in existing work. Together, these nuanced dynamics of exploration suggest that online platforms may be better poised to support users by incorporating different measures of heterogeneous consumption.

AbstractAero-engine component design decisions should consider re-manufacturing and/or repair strategies and their impact on lifecycle cost. Existing design approaches do not account for alternative production technologies such as the use of additive manufacturing in life extension processes. This paper presents a modeling and optimization methodology for examining the impact of design decisions in the early development stage on component lifecycle cost during the in-service phase while considering the potential use of additive manufacturing in life extension strategies. Specifically, a system dynamics model is developed to assess different end-of-life scenarios. Finally, an optimization problem is formulated and solved to minimize lifecycle cost with respect to design variables related to re-manufacturing.

Reducing the lifecycle energy use of buildings with renewable energy applications has become critical given the urgent need to decarbonize the building sector. Multi-objective optimizations have been widely applied to reduce the operational energy use of buildings, but limited studies concern the embodied or whole lifecycle energy use. Consequently, there are issues such as sub-optimal design solutions and unclear correlation between embodied and operational energy in the current building energy assessment. To address these gaps, this study integrates a multi-objective optimization method with building energy simulation and lifecycle assessment (LCA) to explore the optimal configuration of different building envelopes from a lifecycle perspective. Major contributions of the study include the integrated optimization which reflects the dynamics of the whole lifecycle energy use. Insights from the study reveal the optimal configuration of PV and composite building façades for different regions in sub-Saharan Africa. The lifecycle energy use for the optimized building design resulted in 24.59, 33.33, and 36.93% energy savings in Ghana, Burkina Faso, and Nigeria, respectively. Additionally, PV power generation can efficiently cover over 90% of the total building energy demand. This study provides valuable insights for building designers in sub-Saharan Africa and similar areas that minimize lifecycle energy demand.

Understanding the structure and behavior of emissions in building systems is the first step toward improving the reliability of the environmental impact assessment of buildings. The shortcomings of current building lifecycle assessment (LCA) research is the lack of understanding of embodied emissions and static analysis. This study presents a methodology for the dynamic LCA of buildings, combined with the system dynamics technique. Dynamic factors related to recurrent embodied emissions are explored through a literature review. Applying the dynamic factors based on the review, a causal map and stock-flow diagram are invented. Collecting the field data and establishing the assumptions based on the literature, a case study is performed for the proposed model. As a result, through dynamic analysis, it was found that recurrent embodied emissions have a considerably different behavior from static ones during their whole life. Additionally, it was found that the environmental impacts changed by more than 10%, according to the variation of the users’ required performance level in sensitivity analysis. This result thoroughly addressed the necessity and appropriateness of dynamic LCA. The dynamic LCA model developed in this study can contribute to the long-term behavioral understanding of the embodied environmental impacts of building LCA.

The question of resource scarcity and emerging pressure of environmentallegislations have put the manufacturing industry with a new challenge. On theone side, there is a huge population that demands a large quantity ofcommodities, on the other side, these demands have to be met by minimumresources and with permissible pollution that the earth’s ecosystem can handle.In this situation, technologic breakthrough that can offer alternative resourceshas become essential. Unfortunately, breakthroughs do not follow any rule ofthumb and while waiting for a miracle, the manufacturing industry has to findways to conserve resources. Within this research the anatomy of a large body ofknowledge has been performed to find the best available practices for resourceconservation. Critical review of the research revealed that none of the availablesolutions are compatible with the level of resource conservation desired by themanufacturing industry or by society. It has also been discovered that a largegap exists between the solutions perceived by the scientists and theapplicability of those solutions. Through careful evaluation of the state-of-theart,the research presented in this thesis introduced a solution of maximizingresource conservation i.e., material, energy and value added, as used inmanufacturing. The solutions emerged from the novel concept named asResource Conservative Manufacturing, which is built upon the concept ofMultiple Lifecycle of product. Unlike other research work, the researchdocumented in this thesis started with the identification of the problem andfrom which a ‘wish to do’ list was drawn. The seriousness of the problem andpotential of adopting the proposed concept has been justified with concreteinformation. A great number of arguments have been presented to show theexisting gaps in the research and from that, a set of solutions to conserveresources has been proposed. Finally, one of the prime hypotheses concerningclosed loop supply chain has been validated through the system dynamicsmodeling and simulation.

The main parasite affecting the Scottish Atlantic salmon farming industry is Lepeophtheirus salmonis costing approximately £29 million annually through lost production and treatments. As such, the primary aim of this study was to investigate the infection pressure, fecundity and infection dynamics of L. salmonis in a west coast sea loch containing salmonid aquaculture. Atlantic salmon held in small sentinel cages were used to monitor sea lice infection pressure in Loch Shieldaig. Investigation of the factors affecting infection pressure within the loch found no evidence of a direct link between monthly gravid lice counts on local farmed salmon and lice burdens on sentinel cage fish. Copepodid L. salmonis were present throughout the year despite there being low numbers of wild salmonids in the system during much of the year and as such the source of this infection was unclear. In subsequent laboratory trials, L. salmonis from wild salmon were found to be more fecund than those from farmed salmon and similarly, fecundity and survival were also higher in summer compared to winter populations of L. salmonis. These findings raise the possibility that L. salmonis infecting wild salmonids may “seed” previously fallowed systems. Alternatively, trials with atypical hosts found that L. salmonis of farmed origin did re-infect Atlantic cod and produce viable egg strings which moulted through to the infective copepodid stage. Infection challenges demonstrated that L. salmonis copepodids were observed to settle on atypical hosts such as saithe and Atlantic cod in low numbers although failed to develop to the chalimus stages and complete its lifecycle. Challenges utilising the mobile pre-adult stage were similarily unsuccesful in allowing L. salmonis to moult to the adult stage on these atypical hosts. Previous work conducted on Pacific three-spined sticklebacks demonstrated the species could support large burdens. In infection trials with three-spined sticklebacks from Scotland’s west coast, settlement was found to be low, which suggests they play no role in the Scottish inshore infection dynamics of L. salmonis. These series of studies provide novel and timely data on the biology and infection dynamics of L. salmonis on typical and atypical hosts in Scottish marine aquaculture areas. The data will form part of the knowledge used to make informed pest management and policy decisions assisting the future development of the aquaculture industry in Scotland.

Streszczenie:

Les travaux présentés dans cette thèse portent sur la définition du paradigme de régénération issu des principes du développement durable et de l’économie circulaire. L’idée est de limiter l’épuisement des ressources de la sphère naturelle en exploitant les gisements de «déchets» de la sphère technique et en diminuant la production de déchets. La notion de régénération émerge d’une analogie entre la sphère naturelle et la sphère technique, et fait apparaitre les concepts de «nutriments» et de «décomposeurs». Le concept de nutriment permet de revisiter la fin de vie d’équipements domestiques ou industriels, en les voyant comme des nutriments techniques capables de nourrir certaines filières industrielles après transformation. Ces transformations sont opérées par des décomposeurs dans le milieu naturel, et des régénérateurs dans le milieu industriel. Quatre types de régénérateurs ont été définis. Pour chaque type de régénérateurs, des exigences sur le produit devant être satisfaites par les produits «déchets» sont identifiées afin d’assurer la régénération de ces produits. D’autres exigences ont été définies au niveau du processus de régénération pour spécifier les actions de régénération. Ces deux types d’exigences doivent être maintenus tout au long du cycle de vie du produit. La maintenance a été identifiée comme le processus fondamental pour surveiller et maintenir au travers du temps la capacité de régénération et ainsi prolonger la durée de vie des produits. Lorsque les régénérateurs mettent en place une stratégie de régénération, il est nécessaire d’évaluer sa faisabilité. Nous avons donc proposé un outil d’aide à la décision, en modélisant d’une part le comportement du produit au cours de son cycle de vie, ainsi que le comportement des régénérateurs, et d’autre part l’effet des exigences sur le produit et sur le processus. Les modèles choisis sont les System Dynamics qui permettent la modélisation et la simulation des interactions entre les variables d’un système complexe. Cet outil d’aide à la décision permet d’éprouver les propositions de la thèse, au tour d’un exemple de régénération d’un D3E
This thesis is dedicated to the regeneration paradigm from the principles of sustainable development and circular economy. The intention is to limit the exhaustion of natural resources and to reduce waste production through exploiting “waste” deposits of technosphere. The notion of regeneration emerges from an analogy between the natural and technical sphere. It brings to light the concepts of “nutrients” and “decomposers”. The nutrient concept enables to revisit the end of life of domestic or industrial equipment. These equipment are seen as technical nutrients that can feed industrial sectors. The regenerators, called decomposers in nature, are intermediates processors to process “waste” in technical nutrients. Four regenerators have been identified. For each regenerator, product requirements are identified to ensure the regeneration of “waste” product. Additional requirements have been defined in the regeneration process to specify regeneration actions. These two types of requirements must be maintained throughout the product lifecycle. Maintenance process has been identified as fundamental industrial process to monitor and maintain over time the regeneration capability of a product. When regenerators implement a regeneration strategy, it is necessary to assess its feasibility. That is why we proposed a decision- making tool by modeling the product’s behavior during its lifecycle and the regenerator’s behavior, and the effect of the requirements on the product and process. The selected models are System Dynamics. These models allow the modeling and simulation of interactions between the variables of a complex system. The decision-making tool allow test the proposals of this thesis through a regeneration example of an electronic waste

Streszczenie:

Asset allocation is the most influential factor driving investment performance. While researchers have made substantial progress in the field of asset allocation since the introduction of mean-variance framework by Markowitz, there is little agreement about appropriate portfolio choice for multi-period long horizon investors. Nowhere this is more evident than trustees of retirement plans choosing different asset allocation strategies as default investment options for their members. This doctoral dissertation consists of four essays each of which explores either a novel or an unresolved issue in the area of asset allocation for individual retirement plan participants. The goal of the thesis is to provide greater insight into the subject of portfolio choice in retirement plans and advance scholarship in this field. The first study evaluates different constant mix or fixed weight asset allocation strategies and comments on their relative appeal as default investment options. In contrast to past research which deals mostly with theoretical or hypothetical models of asset allocation, we investigate asset allocation strategies that are actually used as default investment options by superannuation funds in Australia. We find that strategies with moderate allocation to stocks are consistently outperformed in terms of upside potential of exceeding the participant’s wealth accumulation target as well as downside risk of falling below that target by very aggressive strategies whose allocation to stocks approach 100%. The risk of extremely adverse wealth outcomes for plan participants does not appear to be very sensitive to asset allocation. Drawing on the evidence of the previous study, the second essay explores possible solutions to the well known problem of gender inequality in retirement investment outcomes. Using non-parametric stochastic simulation, we simulate iv and compare the retirement wealth outcomes for a hypothetical female and male worker under different assumptions about breaks in employment, superannuation contribution rates, and asset allocation strategies. We argue that modest changes in contribution and asset allocation strategy for the female plan participant are necessary to ensure an equitable wealth outcome in retirement. The findings provide strong evidence against gender-neutral default contribution and asset allocation policy currently institutionalized in Australia and other countries. In the third study we examine the efficacy of lifecycle asset allocation models which allocate aggressively to risky asset classes when the employee participants are young and gradually switch to more conservative asset classes as they approach retirement. We show that the conventional lifecycle strategies make a costly mistake by ignoring the change in portfolio size over time as a critical input in the asset allocation decision. Due to this portfolio size effect, which has hitherto remained unexplored in literature, the terminal value of accumulation in retirement account is critically dependent on the asset allocation strategy adopted by the participant in later years relative to early years. The final essay extends the findings of the previous chapter by proposing an alternative approach to lifecycle asset allocation which incorporates performance feedback. We demonstrate that strategies that dynamically alter allocation between growth and conservative asset classes at different points on the investment horizon based on cumulative portfolio performance relative to a set target generally result in superior wealth outcomes compared to those of conventional lifecycle strategies. The dynamic allocation strategy exhibits clear second-degree stochastic dominance over conventional strategies which switch assets in a deterministic manner as well as balanced diversified strategies.

Streszczenie:

The pace of development in the world has increased over the years and with it, the use of hitech gadgets, consumer durables, automobiles etc. has also gone up. In this context, as resources become more and more scarce, there are multiple challenges that emerge both from a sustainable development perspective, and from the perspective of meeting profitability objectives of a firm. Remanufacturing has come up in a big way as an answer to sustainable development challenges, but firms are struggling with respect to revenue management of this nascent area. Remanufacturing as an area is fast becoming an important field as more legislations come in to support it on one hand, and on the other, economic imperatives make it an absolute necessity. We assess the current literature and distil the key factors that firms need to consider as they assimilate remanufacturing in their operations and revenue management strategy. We summarize the key factors that firms need to look into while dealing with remanufactured products from a revenue management perspective into product related, supply chain related and modelling related issues. We establish the current research gaps in this upcoming area and address three of them in our work. Remanufactured products have features similar to new products but are sold at comparably lower prices. This leads to cannibalization of sales of new products from price sensitive customers and affects new product market. However the margins on remanufactured products are higher than new products due to lower material and manufacturing costs. Hence a company would like to meet more of the market demand using remanufactured products. Remanufacturing of used products, unlike new product manufacturing is dependent on supply of used products called cores, as raw material. Supply of used products can become very critical both from perspective of quantity of products available as well as their quality. One of the strategies that can help control the supply of these used products is to consider whether to go for waste stream or market driven used product acquisition. Availability and quality of used products can be severely impacted by choosing one method over the other. Although both cannibalization and market driven used product acquisition have been studied separately by researchers, they have not been dealt with together. First, we address this research gap through our work and derive analytical results for optimal prices and quantities in such a scenario. The problem becomes analytically intractable in this case and we solve it using numerical methods. We show that there are thresholds on willingness to pay for remanufactured products, costs of remanufacturing and new manufacturing which are critical for manufacturers to decide whether they should remanufacture or not. Next we look at the issue of capacity constraints while dealing with new and remanufactured products. We develop models to analyse optimal revenue management policies in the presence of demand cannibalization between new and remanufactured products and a constraint on manufacturing capacity jointly shared by the two product types. We find the situations under which the capacity constraints are binding. We develop optimal policies in this scenario and show that the firm can charge higher prices for both new and remanufactured products in capacitated cases. We also show that as preference for remanufactured products increases, the prices of both the new and remanufactured products increase in the capacitated case. Lastly, we look at lifecycle dynamics while dealing with remanufactured and new products. We consider a firm which has to deal with demand cannibalization as well as lifecycle dynamics of products. We develop models to calculate product returns over all of the previous time periods and incorporate it in a multi-time period profit maximization problem and solve it using dynamic programming. Using computational experiments we show that when preference for remanufactured products is higher, then profitability of firm is very sensitive to products returning from previous periods. Hence the firm should focus on incentivising the quantity as well the quality of returns in such cases. We also show that optimal prices and quantities are very different in initial phases of the lifecycle than the end-of-life phases. We show that the OEM should generally decrease the prices of remanufactured products over the lifecycle and the decrease should be sharper towards the end of life of the product. We also show that when the overall lifecycle length increases, the optimal profits increase sharply with increasing length, and then reaches an upper bound. Thus a firm needs to be more sensitive about shorter lifecycle products.

Streszczenie:

AbstractA Semantic Mediator was conceived in the CRC 637 (The Collaborative Research Centre 637 “Autonomous Cooperating Logistic Processes” focused on adaptive logistic processes including autonomous capabilities for the decentralised coordination of autonomous logistic objects in a heterarchical structure.) to tackle problems of interoperability of heterogeneous information sources in autonomous cooperating logistics processes. Since the conclusion of the CRC 637, the Semantic Mediator has been developed further and successfully transferred to interoperability problems in different domains, including Industry 4.0, the Internet of Things, and Product Lifecycle Management. This paper will introduce the Semantic Mediator and present examples of its successful application.

Streszczenie:

AbstractThe main purpose of this paper is to present knowledge-based Enterprise model (EM) sufficiency as data repository for Unified Modelling Language (UML) models generation. UML models are one of the most usable modelling languages in system lifecycle design stage, despite the problem domain of the system. UML models can be generated from Enterprise Model by using particular transformation algorithms presented in previous researches. Generation process from Enterprise model is represented by certain Hospital Information Management process example. Generated UML dynamic Use Case, Activity, Sequence and State models of different perspectives of Hospital Information Management process prove sufficiency of stored information in Enterprise model.

Streszczenie:

A recent literature within quantitative macroeconomics has advocated the use of continuous-time methods for dynamic programming problems. In this paper we explore the relative merits of continuous-time and discrete-time methods within the context of stationary and nonstationary income fluctuation problems. For stationary problems in two dimensions, the continuous-time approach is both more stable and typically faster than the discrete-time approach for any given level of accuracy. In contrast, for convex lifecycle problems (in which age or time enters explicitly), simply iterating backwards from the terminal date in discrete time is superior to any continuous-time algorithm. However, we also show that the continuous-time framework can easily incorporate nonconvexities and multiple controls—complications that often require either problem-specific ingenuity or nonlinear root-finding in the discrete-time context. In general, neither approach unequivocally dominates the other, making the choice of one over the other an art, rather than an exact science.
