description: This contribution reports on significant improvements achieved in the field of upgraded metallurgical silicon (UMG-Si) as an alternative route to Siemens-refined poly-Si for the manufacture of high-efficiency multicrystalline (mc) silicon solar cells and modules. Recent results in the whole cycle from feedstock production to module performance in the field are summarized. To further improve UMG-Si material quality, we have implemented a multilevel research program, using the charge carrier lifetime at different stages of wafer processing as an effective metric for the assessment of the strategies developed for the upgrading of the material electronic quality. Carrier lifetimes up to 722 µs have been demonstrated by the introduction of an optimized sequential Phosphorus Diffusion Gettering (PDG) which ensures, on the one hand, the non-limiting nature of bulk-related recombination mechanisms in our UMG-Si wafers, and, on the other hand, the suitability of adopting high-efficiency device architectures based on this material. Furthermore, the optimization of metal-assisted nano-texturing and of Al2O3/SiNx-based rear side passivation coating have also been monitored by means of spectrophotometric and carrier lifetime measurements. Remarkable values for the passivation quality have been demonstrated and promising efficiencies in pilot productionline for multicrystalline PERC devices have been obtained. Advanced cell architectures on UMG-Si are currently under investigation, in particular a TOPCore structure, with preliminary tests indicating that efficiencies higher than 22% are within reach. Our results, obtained in the frame of the European SOLAR-ERA-NET CHEER-UP project, indicate the effectiveness of isolated processing actions, compatible with industrial up-scaling, in the upgrading of the electronic performance of mc-UMG-Si wafers; thereby improving the efficiency of related devices and the possibility of implementing advanced device architectures based on mc-UMG material. In this regard, the advantages of UMG-Si related to a lower economic and environmental impact in comparison to standard poly-Si can, in principle, be fully exploited.
title: Feminist Immanent Critique: An Encounter Between Butler, Oksala, and Deleuze
Creators: name: Hernández De La Fuente, Gabriela
Publisher: name: University of Kent
Year: 2022

description: The guiding problem of the thesis is how to reconcile immanence with feminism through the development of the idea of feminist immanent critique. Beginning with Judith Butler's account of the constitution of gender through institutions, and the possibilities of its immanent subversion through a-subjective parodic politics, it is shown that this approach to the problem needs to be augmented by Johanna Oksala's investigation of the way in which the gap between experience and language serves to challenge conceptual schema that organise our experience of the world. However, it is argued that both Butler and Oksala end up reinstating a dogmatic image of the critical subject, although in different manners, thereby forestalling the search for a fully realised response to the problem of feminist immanent critique. Given the return of a dogmatic image of the critical subject, I turn to the most rigorous account of immanence in contemporary philosophy through a reconstruction of key aspects of the work of Gilles Deleuze, one that places ethics at the centre of his thought. It will be shown that the development of immanence with Deleuze provides an account of the subject that does not rely upon dogmatism or abstract from situated forms of social criticism but rather invites such engagement in ways that generate a fruitful encounter with feminism. As the argument is drawn together, it is concluded that feminist immanent critique is a positive conception of critique that requires careful consideration of the ways in which the subject is continually constituted, undone and reconstituted, without reinstating a dogmatic image of the critical subject. Feminist immanent critique embraces an asubjective and, therefore, demoralised version of becoming without losing ethical responsiveness to the present, to ourselves, and to others. That said, it is a positive conception of critique that does not reintroduce transcendence by surreptitiously relying upon a presentist view of time and, as such, it frees becoming from a sense of pre-given direction or telos.

Manufacturing & Production of Si Cells

description: 8th World Conference on Photovoltaic Energy Conversion; 1-6
description: In 1997, a visionary study addressed limitations of the cost reduction potential for high efficiency solar cell devices. The results of this study triggered increased efforts for the development of production technology at Fraunhofer ISE. Many new approaches with substantial impact have been developed to the demonstration level. Economic analysis and a technology readiness terminology have been established to aid in assessing technological approaches, while the set-up of the PV technology evaluation center (PV-TEC) allowed for testing equipment, processes and materials on a higher maturity level. Reference processes building the backbone of the technology have been developed consistently further and device efficiencies follow a roughly 0.5%/a progress gradient since 2005, which is in good agreement with reports for an industrial pilot line. Today, we can rely on reference processes for PERC, TOPCon and SHJ in the PV-TEC with total and large area efficiencies of up to 22.7%, 24.0% and 24.1%, respectively. Further learning includes that for production technology R&D for PV devices high average power conversion efficiencies must be targeted and that scaling should be combined with thorough testing of products along the value chain. All cost and value determining parameters like production efficiency distribution, yield, capital and operational expenditure as well as degradation and performance under field conditions have to be monitored.

description: Miniaturization of force probes into nanomechanical oscillators enables ultrasensitive investigations of forces on dimensions smaller than their characteristic length scale. Meanwhile it also unravels the force field vectorial character and how its topology impacts the measurement. Here we expose an ultrasensitive method to image 2D vectorial force fields by optomechanically following the bidimensional Brownian motion of a singly clamped nanowire. This novel approach relies on angular and spectral tomography of its quasi frequency-degenerated transverse mechanical polarizations: immersing the nanoresonator in a vectorial force field does not only shift its eigenfrequencies but also rotate eigenmodes orientation as a nano-compass. This universal method is employed to map a tunable electrostatic force field whose spatial gradients can even take precedence over the intrinsic nanowire properties. Enabling vectorial force fields imaging with demonstrated sensitivities of attonewton variations over the nanoprobe Brownian trajectory will have strong impact on scientific exploration at the nanoscale.

PV Module Design, Manufacture, Performance and Reliability

description: 38th European Photovoltaic Solar Energy Conference and Exhibition; 803-807
description: The aim of this work is to determine the short-circuit current of colored solar glasses under field conditions, which includes varying solar spectral irradiance, oblique irradiation angles and fractions of diffuse light. Therefore, the field performance of colored building-integrated photovoltaic modules is calculated with spectral solar resource data and angular-dependent spectral responsivity measurements from laboratory testing. This method allows to examine the behavior of modules under test by application of physical laboratory measurements and spectral solar resource data. In order to validate the short-circuit current calculations, monitoring data from field tests are used. In order to assess the results, the short-circuit current is compared with a model using the incidence angle modifier. The results show that the application of angular-dependent spectral responsivity measurements allows to reduce relative mean bias error from 2.26% to 0.25% and relative root mean square error from 2.72% to 1.57% for the blue colored building-integrated photovoltaic module compared to the incidence angle modifier model, respectively.
Conduction-electron spin resonance in two-dimensional structures

description: The infuence of the conduction-electron spin magnetization density, induced in a two-dimensional electron layer by a microwave electromagnetic field, on the rejection and transmission of the field is considered. Because of the induced magnetization and electric current, both the electric and magnetic components of the field should have jumps on the layer. A way to match the waves on two sides of the layer, valid when the quasi-two-dimensional electron gas is in the one-mode state, is proposed. By following this way, the amplitudes of transmitted and rejected waves as well as the absorption coefficient are evaluated.

Period-Luminosity-Colour Relation for Early-Type Contact Binaries
Creators: name: Pawlak, Michal
Publisher: name: arXiv
Year: 2016
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: This work describes the analysis of 64 early-type, massive contact or near-contact eclipsing systems from the Large Magellanic Cloud discovered by the OGLE-III survey. It presents the determination of the period-luminosity-colour relation followed by these objects, that is different from the one previously known for late-type W UMa stars. The relation for massive stars has a significantly steeper dependence on the colour, which is related to a much higher bolometric correction, however it is shallower in the period term. This leads to the conclusion, that the relation for the total population of main sequence contact binaries is non-linear. When studied separately, genuinely-contact and near-contact systems follow two slightly different relations.

description: The purpose of this study is to assess Total Quality Management (TQM) practices in Ethiopian pharmaceuticals S.C. TQM is a factor of its principles and practices namely customer focus, Leadership, Engagement of People, Process Approach, Evidence based decision making and Supplier relationship. Hence, the research tried to assess whether these principles are practiced in the organization.The research tried to obtain both primary and secondary data. The primary data was obtained from employees of Epharm using semistructured questionnaire and Interview questions The secondary sources of data were the literatures available and the documents related to TQM that are kept by the organization.The data collected was analyzed and presented with tables and percentages using SPSS. Furthermore to estimate error or how well the sample represented the population, confidence interval method was employedThe general population of the research is all 220 employees of Epharm. These 220 employees are of different departments, experience and exposure to quality related issues.33 out of these 220 employees are managers and supervisors thus 187 employees are non-managers.Since quality is a factor of all the parties in an organization, all 220 employees from all departments have chance to be included in the sample. However,different sampling techniques employed for each department. The results of this paper shows that majority of the employees agree that Epharm is practicing all the seven TQM principles. Results of Interview questions about the benefits and challenges of practicingTQM, shows that all the respondents agree that it makes dramatic change on the way things done throughout the organization. Besides the change process starting form Top management down to all employees of the organization was too hard to adopt at that time. There were some uncertainties, higher costs and higher turnover of employees, who gets it hard to adapt the new paradigm shift towards new philosophy, was the main challenges the organization face during the early stage of practicing TQM system. Review of company documents also show that the company is showing progress through time to time after started practicing TQM system.

description: As stated by the European Green Deal, the transition to low-emission or near-zero energy systems, equipped with modern and efficient structures, represents a priority addressed at the European level, from the technological, organizational, and educational point of view. One of the challenges that support the demand for technical specialists for a sustainable future in the field of renewable energy and green mobility is to keep up with the evolution of scientific results, equipment, and developed strategies. In this respect, the European educational systems are interested to develop specific competencies, starting from primary and secondary levels. In order to support the skills acquired in the classrooms, the interventions of academic teachers and scientific researchers are relevant for the dissemination of scientific developments at the international level. In this context, in the frame of the CONNECT project, a particular science action has been developed, oriented on “Sustainable future: solar energy and green mobility”. The volume of information brings to the attention of young people theoretical elements in the field of solar energy, applications with photovoltaic systems, and possibilities of storing photovoltaic energy in hydrogen production. Targeting also to stimulate the orientation of youngers toward science and technology, the most efficient application relied on photovoltaic systems in Romania are presented, as well as those developed in Valahia University of Targoviste. In addition, an important emphasis is placed on the possibilities for developing ecological mobility.

description: Lenticular galaxies (S0s) represent the majority of early-type galaxies in the local Universe, but their formation channels are still poorly understood. While galaxy mergers are obvious pathways to suppress star formation and increase bulge sizes, the marked parallelism between spiral and lenticular galaxies (e.g. photometric bulge-disc coupling) seemed to rule out a potential merger origin. Here, we summarise our recent work in which we have shown, through N-body numerical simulations, that disc-dominated lenticulars can emerge from major mergers of spiral galaxies, in good agreement with observational photometric scaling relations. Moreover, we show that mergers simultaneously increase the light concentration and reduce the angular momentum relative to their spiral progenitors. This explains the mismatch in angular momentum and concentration between spirals and lenticulars recently revealed by CALIFA observations, which is hard to reconcile with simple fading mechanisms (e.g. ram-pressure stripping).

description: This paper introduces two objective functions for computing the expected cost in the Stochastic Collection and Replenishment (SCAR) scenario. In the SCAR scenario, multiple user agents have a limited supply of a resource that they either use or collect, depending on the scenario. To enable persistent autonomy, dedicated replenishment agents travel to the user agents and replenish or collect their supply of the resource, thus allowing them to operate indefinitely in the field. Of the two objective functions, one uses a Monte Carlo method, while the other uses a significantly faster analytical method. Approximations to multiplication, division and inversion of Gaussian distributed variables are used to facilitate propagation of probability distributions in the analytical method when Gaussian distributed parameters are used. The analytical objective function is shown to have greater than 99% comparison accuracy when compared with the Monte Carlo objective function while achieving speed gains of several orders of magnitude.

External inverse-Compton emission from jetted tidal disruption events

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: The recent discoveries of Swift J1644+57 and J2058+05 show that tidal disruption events (TDEs) can launch relativistic jets. Super-Eddington accretion produces a strong radiation field of order Eddington luminosity. In a jetted TDE, electrons in the jet will inverse-Compton scatter the external radiation field from the accretion disk and wind. Motivated by observations of thermal optical-UV spectra in Swift J2058+05 and several other TDEs, we assume the spectrum of the external radiation field intercepted by the relativistic jet to be blackbody. Hot electrons in the jet scatter this thermal radiation and produce luminosities 10^45-10^48 erg/s in the X/gamma-ray band. This model of thermal plus inverse-Compton radiation is applied to Swift J2058+05. First, we show that the blackbody component in the optical-UV spectrum most likely has its origin in the super-Eddington wind from the disk. Then, using the observed blackbody component as the external radiation field, we show that the X-ray luminosity and spectrum are consistent with the inverse-Compton emission, under the following conditions: (1) the jet Lorentz factor is ~5-10; (2) electrons in the jet have a powerlaw distribution with minimum Lorentz factor ~1 and powerlaw index p = 2.4; (3) the wind is mildly relativistic (Lorentz factor >~1.5) and has isotropic-equivalent mass-loss rate ~5 M_sun/yr. We describe the implications for jet composition and the radius where jet energy is converted to radiation.

description: The Training and Evaluation Platform of the French National Institute of Solar Energy (INES PFE) is a training center dedicated to solar energy. Previously, most training sessions organized by INES PFE were based on an inconvenient and outdated training platform initially designed for the residential PV market. In order to drive capacity building for stakeholders involved in the planning, design, operation and maintenance of PV systems, INES PFE decided in 2019 to design a new training platform, equipping it with cutting edge systems and components used worldwide. The aim of this paper is to describe the technical features of the training platform and in particular two models, one dedicated to PV systems with storage for non-interconnected grids, another dedicated to the connection of large-scale PV systems to the Medium Voltage grid, developed in partnership with Hespul, a French not-for-profit organization specialized in the promotion of PV.

description: The development of hadronic cascades in extensive air-showers is modeled by hadronic interaction models based on extrapolations of accelerator data. The models' predictions at the highest energies (above $∼10^{18}~eV$) are at a known tension with the description of measurements of the muonic component, if the mass composition derived from the fluorescence detection technique is assumed. We apply an ad-hoc modification to the CORSIKA Monte-Carlo generator that allows for adjustment of features of hadronic interactions such as multiplicity, elasticity and cross-section. Compared to similar previous studies, we are now able to obtain not only information related to the longitudinal development of the shower, such as the mean depth of shower maximum, but also information about the lateral distribution of particles. Moreover, we generate a scan across the various possible combined modifications of the Sibyll 2.3d model using proton-initiated showers, quantify their effects on both the lateral and longitudinal features of a cosmic-ray shower and identify regions of the modification phase space which are promising for the explanation of both the ground-based and fluorescence-based measurements of cosmic rays at the highest energies.

description: Defect engineering has brought about a unique level of control for Si-based semiconductors, leading to the optimization of various opto-electronic properties and devices. With regard to perovskite transition metal oxides, oxygen vacancies have been a key ingredient in defect engineering, as they play a central role in determining the crystal field and consequent electronic structure, leading to important electronic and magnetic phase transitions. Therefore, experimental approaches toward understanding the role of defects in complex oxides have been largely limited to controlling oxygen vacancies. In this study, we report on the selective formation of different types of elemental vacancies and their individual roles in determining the atomic and electronic structure of perovskite SrTiO3 (STO) homoepitaxial thin films fabricated by pulsed laser epitaxy. Structural and electronic transitions have been achieved via selective control of the Sr and oxygen vacancy concentrations, respectively, indicating a decoupling between the two phase transitions. In particular, oxygen vacancies were responsible for metal-insulator transitions, but did not influence the Sr vacancy induced cubic-to-tetragonal structural transition in epitaxial STO thin film. The independent control of multiple phase transitions in complex oxides by exploiting selective vacancy engineering opens up an unprecedented opportunity toward understanding and customizing complex oxide thin films.

description: The AgroFossilFree project is supporting Fossil-Energy-Free Technologies and Strategies (FEFTS) in agriculture by coordinating several stakeholder actions and by providing information on FEFTS in agriculture. Thereby, special emphasis is placed on applications of photovoltaics (PV) in agriculture. The core objective of the project is to set-up an online platform for farmers, advisors, researchers, industrial partners and other actors on which they can find useful information on FEFTS in agriculture. The AgroFossilFree project contributes to the High Level EU Strategies (i.e. EU Green Deal and Farm to Fork strategy) as it aims to decrease the use of fossil energy in any farming process. It also contributes to close the gap between the available FEFTS and the everyday EU agricultural practices by promoting effective exchange of novel ideas and by exchanging information between research, industry, extension services and the farming community. If this gap closes, European agriculture could become more sustainable with minimum energy, environmental and socioeconomic impacts. With the knowledge that is collected, classified and presented to actors in the agricultural field, the European agricultural sector is able to promote and comply with the fossil energy use reduction policies, the related legal and regulatory frameworks and sustainable food production practices. This paper presents the current status of the AgroFossilFree project which is funded by the Horizon 2020 Programme of the European Commission.

description: Consider the primitive equations on R² × (z₀, z₁) with initial data a of the form a = a₁ + a₂, where a₁ ∈ BUCσ (R²; L¹(z₀, z₁)) and a₂ ∈ L∞ σ (R²; L¹(z₀, z₁)). These spaces are scaling-invariant and represent the anisotropic character of these equations. It is shown that for a₁ arbitrary large and a₂ sufficiently small, this set of equations admits a unique strong solution which extends to a global one and is thus strongly globally well posed for these data provided a is periodic in the horizontal variables. The approach presented depends crucially on mapping properties of the hydrostatic Stokes semigroup in the L∞(L¹)-setting. It can be seen as the counterpart of the classical iteration schemes for the Navier–Stokes equations, now for the primitive equations in the L∞(L¹)-setting.

description: Worldwide, three-quarter of a billion people live without electricity. Besides, hundreds of million use a solar lantern a few hours a day. Solar photovoltaic powered mini-grids are increasingly extending improved energy access to deprived regions. However, poor load-factor and expensive storage adversely impact reach and growth. Moreover, these mini-grids commonly do not support intermittent large loads to avoid drooping resource utilization. Though electric cooking is very efficient and non- polluting, feeble mini-grids struggle to power these. Comparable supply constraints affect water treatment infrastructure that can potentially save millions from contaminant and pathogen impacted water. In cold climates, space heating remains essential but may not be supported by the electric supply system. Washing machines are efficient in terms of water usage but need appropriate supply to operate. Consumers can collaborate to avoid some of these challenges but education and awareness of the prevailing situation and the potential can help in solar PV proliferation. Though solar PV is still perceived by many communities as suitable for tiny loads only, education, awareness and suitable ecosystem can change that. Increasingly, solar PV can integrate well into the supply infrastructure and eventually become the backbone of distributed 100% renewable sourced communities across nations and geographies.

description: 360-degree image and film content has gained popularity in the media and in the MICE industry (Meeting, Incentive, Conventions and Exhibitions). There are several reasons for this development. On the one hand, it is the immersive character of this media form, on the other hand, the development of recording and presentation technology has made considerable progress in resolution and quality. Additionally, after a decade of dynamic growth, the MICE industry is focusing on a disruptive shift towards more digitally based solutions. 360-degree panoramas are particularly prevalent in VR and AR technology. The aim is to project 360-degree content in specially equipped rooms to provide a shared experience for the audience. One area of application for 360-degree panoramas and films in particular is conference rooms in hotels, conference centre and other venues that want to create an immersive environment for their customers. The aim of this paper is to give an overview of the different application scenarios and possible uses in terms of customer centricity for such conference rooms. These applications and usage scenarios were successfully tested and implemented in the 360-degree conference room "Dortmund" at the Hotel Park Soltau in Soltau, Germany. Finally, the advantages, challenges and limitations of this proposed approach are described.

description: In the deployment of photovoltaic systems in the residential and commercial sectors, rooftop solar scheme such as feed-in-tariffs (FIT) have had a significant impact. Although this impact benefits the prosumer, the regulation of feed-in-tariffs based on time of generation (ToG) is an important factor for further growth of its integration. The methodology framework for setting feed-in-tariffs based on time of generation is proposed and evaluated in this paper. In contrast with the conventional feed-in-tariffs and the proposed feed-in-tariffs for a simulation model, the return on investment is observed to be more due to maximized total savings upon integration of grid connected photovoltaic (PV) system. Upon investigation of the proposed framework in this paper, it was found that the total savings would be 6.87% more than the current policy adopted worldwide.

description: This research paper aims to identifying factors which influence the adoption of agent banking by commercial Bank of Ethiopia. Clear understanding of these factors will enable agent banking service providers to develop suitable marketing strategies, business models, processes, and pilot projects. To address the research objective 126 sampled customers were selected. Purposive and convenience sampling methods were used. Questioners were distributed to 126 different managers, from which 117 sample respondents replied appropriately to the questionnaire. Data gathered were analyzed based on these 117 responses using SPSS 20 software package. Descriptive statistics and explanatory research approach were employed. All out puts were reported using frequency, mean, correlation and multiple linear regression analysis results such as ANOVA and coefficient and regression results were used. The result indicates that Compatibility, perceived support, perceived trust, Perceived Benefit, and Financial Literacy major factors influencing adoption of CBE Birr Service. But security factors were not significant. Among these factors Financial Literacy, and Perceived trust were the most statistically significant factors adopting agency banking. Financial literacy found to have a positive significant influence on mobile money adoption. This implies that users' knowledge, ability and skills are needed to use the new information technology. The study recommended that adoption can be increased by developing better functions in terms of flexibility, security and accessibility features to enhance consumers' confidence to adopt CBE Birr services and users' knowledge, ability and skills are needed to use the new information technology. Available support structures and strong top management support becomes an essential measure to encourage CBE Birr adoption.

description: We suggest the measurement of Drell-Yan (DY) lepton pairs in p-Pb collisions at the LHC (sqrt(s)=5.02 TeV) in order to disentangle the relative contributions of shadowing and coherent energy loss in quarkonium production off nuclei. The nuclear modification of low mass DY production is computed at NLO using various sets of nuclear parton densities. It is then observed that shadowing effects strongly cancel out in the J/psi over DY suppression ratio R_{pA}^{J/psi}(y) / R_{pA}^{DY}(y), unlike the effect of coherent energy loss. Such a measurement could be performed at forward rapidity by the ALICE and LHCb collaborations at the LHC.

description: Buildings play an important role in everyone's life: they serve as homes, workplaces, schools, shopping centres, hospitals or other public buildings. Nevertheless, about 75% of the EU building stock is not energy efficient, leading to a large amount of the energy produced being wasted. To minimize energy loss, existing buildings need to undergo energy efficient renovations. However, there is a particular deficit in finding suitable financing schemes for the implementation of energy efficiency measures. Innovative financing solutions are needed to enable energy-efficient retrofits on a large scale and to strengthen collaboration between all stakeholders (project promoters, public/private financial institutions, end-users) and especially with citizens. Based on the ongoing research activities in the frame of the H2020 European project CitizEE, this paper presents the latest advancements of the innovative Citizen Financing Scheme of the Pilot VIPA based in Lithuania. The VIPA scheme enables citizens to become prosumers (people who both consume and produce electricity) through the combination and leveraging of different funding sources.

description: This paper proposes a novel electricity price prediction method using past electricity demand. The previous method predicts the electricity price using LSTM after wavelet transform of the past electricity price series. Wavelet transform decomposes the series into more smooth and stable series, and accurate prediction is performed by LSTM with these series. The proposed method also uses the electricity demand series, and the demand is also applied wavelet transform for effective LSTM step. Experimental results show the effectiveness of the proposed method, and the accuracy is drastically improved over the previous method.

description: During the development of a photovoltaic plant project, the expected energy yield plays a key role for financial viability. Up to now, the uncertainty of the potential yield is dominated by the solar resource risk. The evaluation of solar resource for an average geographical situation still shows an uncertainty of approximately 5%. This risk can be significantly reduced by adaption to the specific site using qualified ground-based measurements. By measurements of highest quality and multiple years of overlap with satellite timeseries, the uncertainty of the solar resource may be reduced to a minimum of 2%. Such high accuracy of solar resource data sharpens forecasted project yields and improves financing terms. This study shows the impacts of on-site measurements to leveraged project finance and project value. Results show that costs for a one-year measurement campaign already pay off for plant sizes in the order of 10 MW. Moreover, the direct impact by high-quality on-site solar measurements translates into an increase of up to 200 kUSD each 10 MW.

description: Robots have a finite supply of resources such as fuel, battery charge, and storage space. The aim of the Stochastic Collection and Replenishment (SCAR) scenario is to use dedicated agents to refuel, recharge, or otherwise replenish robots in the field to facilitate persistent autonomy. This paper explores the optimisation of the SCAR scenario with a single replenishment agent, using several different objective functions. The problem is framed as a combinatorial optimisation problem, and A* is used to find the optimal schedule. Through a computational study, a ratio objective function is shown to have superior performance compared with a total weighted tardiness objective function, with a greater performance advantage present when using shorter schedule lengths. The importance of incorporating uncertainty in the objective function used in the optimisation process is also highlighted, in particular for scenarios in which the replenishment agent is under- or fully-utilised.
