Purpose The emergence of mega-farms in middle-income countries like Brazil and Ukraine and the efforts to consolidate small farms into larger ones in China and elsewhere have suggested that new institutional arrangements and technology progress may increase the significant farm economies of size, and therefore challenging the classical inverse relationship (IR) between productivity and farm size. The purpose of this paper is to conduct a research to examine the existence of IR in China’s cereal production and further explore the possible mechanism. Design/methodology/approach Based on the panel data concerning farms from 31 provinces in China in 2009–2014, technology efficiency and allocation efficiency in cereal production were measured based on the Translog production function. Findings In China, an IR exists between wheat, rice and maize production after controlling the related variables. Further, the presence of this IR is due to allocation efficiency rather than technology efficiency. Results of technology efficiency show that there is no significant difference between different size groups; in other words, even the larger size groups enjoy a higher technology efficiency in rice production. Results of allocation efficiency demonstrate that, compared with the larger farms, smaller holders tend to invest more in factors which are beneficial in growing productivity. Hence, yields of small-size farms exceed those of large-size farms, which consequently leads to the IR. Practical implications The scale consolidation of cropland is harmless to the efficiency of factor utilization and, conversely, may contribute in improving the technology efficiency of specific crops (like rice). Based on the results of allocation efficiency estimation, the extent of misallocation in large scales is relatively less due to their less input of fertilizer and pesticide; thus, the size-improving policy of farmland may contribute to the ease of the non-point pollution in agriculture. Originality/value The existing discussions of the IR in the context of recent China mainly focus on the accurate verification of IRs. This paper steps forward from the perspective of technology efficiency and allocation efficiency and explores the exact resources of IR with up-to-date and representative data and hopes to find some new conclusions.

Improving the energy-efficiency of computing systems has been the focus of computer science research for many decades. In the data center domain, for example, there has been an intense focus on improving energy efficiency by improving the Power Usage Effectiveness (PUE) of data centers. Other domains such as civil and mechanical engineering have also focused on improving the energy efficiency of built environments such as buildings. More recently, there has been an increased emphasis on sustainability on the human-built infrastructure of various kinds motivated by climate change, which has resulted in an emphasis on reducing carbon emissions of such infrastructure by optimizing their carbon efficiency.

Consumerism is on the list of critical targets of ecological economists, but an economic theory of consumerism has still to be developed. The present paper intends to contribute to such a theory based on an institutionalist view of consumption as a social process and focussing on the interrelations between consumers as skilled social agents, infrastructures and institutions. In the present paper consumption is understood as the life-process encompassing all kinds of social activities necessary to the life-enjoyment objective of socialized and culturally determined individuals. In their consumption activities, individuals have to move between different types of institutions (the market, the firm, the state, personal relations, etc.) with the aim of successfully organizing their life-processes. Consumers are therefore potentially creative and consumption may become an important source of social and environmental innovation. Innovative behaviour involves a change in the relationship between consumers, infrastructures and institutions and its outcome may be evaluated under different criteria. The present paper suggests a comparison of three types of efficiency: ecological, economic and time efficiency. In order to illustrate the here proposed view, some environmental problems of the transportation system are discussed.

Le principal objectif de cette thèse est d'expliquer en quoi l’efficience statique (static efficiency), l’efficience de coordination (coordinative efficiency) et l’efficience créative (creative efficiency) jouent un rôle déterminant dans la conception de la gouvernance à l'ère numérique. Il s’agit également d’étudier des mécanismes originaux de gouvernance, au-delà de la traditionnelle dimension marché-hiérarchie, pouvant faciliter les processus de coordination intégrative (integrative coordination) ainsi que de création collective dans les organisations.La thèse comprend trois essais. Le premier est une contribution de nature théorique montrant que l’économie des coûts de transaction (Williamson 1979, 1991, 1996, 2002) ne permet pas de rendre compte de façon satisfaisante de la conception de la gouvernance à l’ère numérique. Le modèle conceptuel normatif proposé contribue à repenser celle-ci dans une perspective pluraliste intégrant complexité et variété. Les choix de gouvernance ne sont ainsi plus limités à la seule dimension marché-hiérarchie comme le laisse penser l’économie des coûts de transaction. Une perspective intégrant la construction sociale des modes d’organisation (Giddens, 1985; Greenwood et al. 2011) permet de définir une variété de formes de gouvernance. Il est possible de représenter, dans un espace à trois dimensions (efficience statique, efficience de coordination et efficience créative), les différentes configurations de gouvernance sous la forme d’un triangle. Cette représentation peut être appliquée afin de rendre compte des choix de gouvernance possibles à différents niveaux organisationnels.Les deux essais suivants sont à dominante empirique. Ils visent à prolonger le premier en étudiant le lien entre des configurations innovantes de gouvernance et la performance des organisations en matière d’efficacité de coordination et d’efficacité créative. Le deuxième essai se concentre sur la coordination d’intégration dans les organisations. Des structures organisationnelles distribuées à plusieurs couches ou layered distributed organizational structures (Simon, 1962), des plans définis ex ante de façon imprécise ou broad-brushed ex ante plans (Edmondson, Bohmer et Pisano, 2001), ainsi que des semi-structures (Brown et Eisenhardt, 1997) s’avèrent utiles au processus de coordination lorsque les interdépendances sont complexes et incertaines. Le troisième essai porte sur la performance des organisations en matière de créativité collective. Il s’intéresse notamment aux dispositifs organisationnels facilitant l’émergence d’une telle créativité tout en préservant stabilité et efficacité. Plusieurs formes de perturbation qualifiées d’ordonnées (ordered disruption), tant au niveau spatial (ordered spatial disruption) que temporel (ordered temporal disruption) et affectif (ordered affective disruption), contribuent à l'émergence de la créativité collective.Le matériel empirique utilisé dans les deuxième et troisième essais provient d’une étude des modes de gouvernance de différents projets de villes intelligentes (smart-cities) nécessitant une collaboration entre plusieurs organisations
The main objective of this dissertation is to explain why coordinative efficiency, creative efficiency, together with static efficiency are all critical goals of governance design in digital age, and to explore innovative governance arrangements, beyond the one-dimensional line defined by “market” and “hierarchy”, that can facilitate the processes of integrative coordination, and collective creation in organizations.The dissertation is composed of three essays. Essay 1 is a theory paper that provides the overall theoretical arguments about why transaction cost economics (Williamson 1979, 1991, 1996, 2002) is no longer a satisfactory theoretical framework for governance design in the digital age, and offers a normative model which suggest possibilities of much more nuanced, complicated and pluralistic governance choices than suggested by transaction cost economics. It is argued that potential governance choices are not solely situated on a one-dimensional line between hierarchy and market, as transaction cost economics asserts. The rich connotations of socially constructed agency (Giddens, 1985; Greenwood et al. 2011) provide diverse possibilities of governance arrangements, which spread across a triangular plane in a three-dimensional space defined by static efficiency, coordinative efficiency and creative efficiency (see Figure 1). This paper provides both graphic and mathematical presentations of this three-dimensional model for governance design, which can be applied to different levels of organizing.Essay 2 and 3 are two empirical papers that endeavor to extend Essay 1 by finding out the exact relationship between certain innovative governance arrangements with organizations’ performance in coordinative and creative efficiencies. Essay 2 focuses on the realization of integrative coordination in organizations. It found out that layered distributed organizational structure (Simon, 1962), broad-brushed ex ante plan (Edmondson, Bohmer and Pisano, 2001), and semi-structures (Brown and Eisenhardt, 1997) are beneficial in facilitating an ongoing coordination process when interdependencies are complex and uncertain. Essay 3 focuses on organizations’ performance in collective creativity (Shalley et al., 2004; George, 2007), especially on what governance arrangements can best allow collective creativity to emerge without overly sacrificing organizational stability and efficiency. It is discovered that “ordered disruption”, including ordered spatial disruption, ordered temporal disruption and ordered affective disruption, have positive effects on the emergence of collective creativity. Both Essay 2 and Essay 3 use collaborative organizations on smart city projects as the empirical setting. The findings of these two empirical papers are grounded on multiple case studies on those collaborative organizations

The energy consumption of the first world has reached unexpected heights, and is increasing every day. Because of this, energy efficiency has become a hot subject, both on a small and large scale. Every individual has a possibility to improve their energy efficiency and energy use alike by substantial amounts, and should act on this for the sake of the environment. The report begins with a study of different regulations and standards regarding energy efficiency. After this, a literature study is conducted regarding the latest available technology in all areas of home appliances. Finally, a field study is conducted on an apartment in Stockholm to find out how much energy that actually can be saved, and what the economic results are from this. The result shows that in general, it isn’t economically viable to upgrade to the latest energy efficient technology within home appliances, but that one has to consider the environmental gains as incitement for action. Approximately 10% of the total annual energy consumption could be saved by changing all machinery and functions in the house, except the heating, ventilation and air conditioning part.
Västvärldens energianvändning har nått oanade höjder, och ökar varje dag. Därför har energieffektivitet blivit ett hett ämne, både på liten och stor skala. Varje enskild individ har möjlighet att förbättra sin energieffektivitet och därmed sin energianvändning med märkbara skillnader, och bör agera därefter för miljöns skull. Rapporten börjar med en studie av olika regleringar och bestämmelser om energieffektivitet. Efter det kommer en litteraturstudie om vilken teknik som finns tillgänglig inom alla delar av hemmets energianvändning. Slutligen utförs en fältstudie på en lägenhet i Stockholm för att avgöra hur mycket energi som kan sparas, och vilka ekonomiska följder detta har. Resultatet visar att det i allmänhet inte är ekonomiskt hållbart att byta till den senaste energieffektiva tekniken inom hemmets apparater, utan att man får avse de miljömässiga vinsterna som incitament för dessa uppgraderingar. Ungefär 10% av den totala årliga energianvändningen kunde sparas genom att åtgärda alla apparater och funktioner i huset, utan avseende på uppvärmning och isolering.

Impeding Efficiency is based on my interest in the manner in which we experience space and in particular, the moment we become conscious of our surrounding built environment. The point of change between spaces, the threshold. Contemporary society lives in fast-forward; everything we do has been streamlined, developed in principles of efficiency. This phenomenon has caused a divide between user and the experience of architecture. We move rapidly, only with goal in mind, very rarely pausing, to adjust and reflect on our surroundings. This sparked a study of the threshold in architecture through the lens of four architects and the architectural strategies they have applied in a manner that impedes efficiency, hinders mobility, slows down time and allows for personal interpretation of the build environment.

As wireless communication becomes an ever-more important and pervasive part of our everyday life, system capacity and quality of service issues are becoming more critical. In order to increase the system capacity and improve the quality of service, it is necessary that we pay closer attention to bandwidth and power efficiency issues. Orthogonal Frequency Division Multiplexing (OFDM) is a multicarrier modulation technique for high speed data transmission and is generally regarded as bandwidth efficient. However, OFDM signals suffer from high peak-to-average power ratios (PARs) which lead to power inefficiency in the RF portion of the transmitter. Moreover, in OFDM, the well-known pilot tone assisted modulation (PTAM) technique utilizes a number of dedicated training pilots to acquire the channel state information (CSI), resulting in somewhat reduced bandwidth efficiency. In this dissertation, we will address the above mentioned bandwidth and power efficiency issues in wireless transmissions. To avoid bandwidth efficiency loss due to dedicated training, we will first develop a superimposed training framework that can be used to track the frequency selective as well as the Doppler shift characteristics of a channel. Later on, we will propose a generalized superimposed training framework that allows improved channel estimates. To improve the power efficiency, we adopt the selected mapping (SLM) framework to reduce the PARs for both OFDM and forward link Code Division Multiple Access (CDMA). We first propose a dynamic SLM algorithm to greatly reduce the computational requirement of SLM without sacrificing its PAR reducing capability. We propose a number of blind SLM techniques for OFDM and for forward link CDMA; they require no side information and are easy to implement. Our proposed blind SLM technique for OFDM is a novel joint channel estimation and PAR reduction algorithm, for which bandwidth efficiency power efficiency - complexity - bit error rate tradeoffs are carefully considered.

In this paper we combine ideas from cutting plane and interior point methods in order to solve variational inequality problems efficiently. In particular, we introduce a general framework that incorporates nonlinear as well as linear "smarter" cuts. These cuts utilize second order information on the problem through the use of a gap function. We establish convergence as well as complexity results for this framework. Moreover, in order to devise more practical methods, we consider an affine scaling method as it applies to symmetric, monotone variationalinequality problems and demonstrate its convergence. Finally, in order to further improve the computational efficiency of the methods in this paper, we combine the cutting plane approach with the affine scaling approach.

L'une des stratégies utilisée pour augmenter l'efficacité spectrale (ES) des réseaux cellulaires est de réutiliser la bande de fréquences sur des zones relativement petites. Le problème majeur dans ce cas est un plus grand niveau d'interférence, diminuant l'efficacité énergétique (EE). En plus d'une plus grande largeur de bande, la densification des réseaux (cellules de petite taille ou multi-utilisateur à entrées multiples et sortie unique, MU-EMSO), peut augmenter l'efficacité spectrale par unité de surface (ESuS). La consommation totale d'énergie des réseaux sans fil augmente en raison de la grande quantité de puissance de circuit consommée par les structures de réseau denses, réduisant l'EE. Dans cette thèse, la région EE-SE est caractérisé dans un réseau cellulaire hexagonal en considérant plusieurs facteurs de réutilisation de fréquences (FRF), ainsi que l'effet de masquage. La région EE-ESuS est étudiée avec des processus de Poisson ponctuels (PPP) pour modéliser un réseau MU-EMSO avec un précodeur à rapport signal sur fuite plus bruit (RSFB). Différentes densités de station de base (SB) et nombre d'antennes aux SB avec une consommation d'énergie statique sont considérées.Nous caractérisons d'abord la région EE-SE dans le réseau cellulaire hexagonal pour différentes FRF, avec et sans masquage. Avec le masquage en plus de la perte de propagation, la mesure de coupure ε-EE-ES est proposée pour évaluer les performances. Les courbes EE-ES présentent une grande partie linéaire, due à la consommation de puissance statique, suivie d'une forte diminution de l'EE, puisque le réseau est homogène et limité par les interférences. Les résultats montrent qu'un FRF de 1 pour les régions proches de la SB et des FRF plus élevés dans la région plus proche du bord de la cellule améliorent le point optimal du EE-ES. De plus, un meilleur compromis EE-ES peut être obtenu avec une valeur plus élevée de coupure. En outre, un FRF de 1 est le meilleur choix pour une valeur élevée de coupure en raison d'une réduction du rapport signal sur interférence plus bruit (RSIB).Les précodeurs sont utilisés en liaison descendante des réseaux cellulaires MU-EMSO à accès multiple par division spatiale (AMDS) pour améliorer le RSIB. La géométrie stochastique a été utilisée intensivement pour analyser de tels systèmes complexes. Nous obtenons une expression analytique de l'ESuS en régime asymptotique, c.-à-d. nombre d'antennes et d'utilisateurs infinis, en utilisant des résultats de matrices aléatoires et de géométrie stochastique. Les SBs et les utilisateurs sont modélisés par deux PPP indépendants et le précodage RSFB est utilisé. L'EE est dérivée d'un modèle de consommation de puissance linéaire. Les simulations de Monte Carlo montrent que les expressions analytiques sont précises même pour un nombre faible d'antennes et d'utilisateurs. De plus, les courbes d'EE-ESuS ont une grande partie linéaire avant une forte décroissante de l'EE, comme pour les réseaux hexagonaux. Les résultats montrent également que le précodeur RSFB offre de meilleurs performances que le précodeur forçage à zéro (FZ), qui est typiquement utilisé dans la literature. Les résultats numériques pour le précodeur RSFB montrent que déployer plus de SBs ou d'antennes aux BSs augmente l'ESuS, mais que le gain dépend du rapport des densités SB-utilisateurs et du nombre d'antennes lorsque la densité de l'utilisateur est fixe. L'EE augmente seulement lorsque l'augmentation de l'ESuS est plus importante que l'augmentation de la consommation d'énergie par unité de surface. D'autre part, lorsque la densité d'utilisateur augmente, l'ESuS dans la région limitée par les interférences peut être améliorée en déployant davantage de SB sans sacrifier l'EE et le débit ergodique des utilisateurs
One of the used strategies to increase the spectral efficiency (SE) of cellular network is to reuse the frequency bandwidth over relatively small areas. The major issue in this case is higher interference, decreasing the energy efficiency (EE). In addition to the higher bandwidth, densification of the networks (e.g. small cells or multi-user multiple input single output, MU-MISO) potentially increases the area spectral efficiency (ASE). The total energy consumption of the wireless networks increases due to the large amount of circuit power consumed by the dense network structures, leading to the decrease of EE. In this thesis, the EE-SE achievable region is characterized in a hexagonal cellular network considering several frequency reuse factors (FRF), as well as shadowing. The EE-ASE region is also studied using Poisson point processes (PPP) to model the MU-MISO network with signal-to-leakage-and-noise ratio (SLNR) precoder. Different base station (BS) densities and different number of BS antennas with static power consumption are considered.The EE-SE region in a hexagonal cellular network for different FRF, both with and without shadowing is first characterized. When shadowing is considered in addition to the path loss, the ε-SE-EE tradeoff is proposed as an outage measure for performance evaluation. The EE-SE curves have a large linear part, due to the static power consumption, followed by a sharp decreasing EE, since the network is homogeneous and interference-limited. The results show that FRF of 1 for regions close to BS and higher FRF for regions closer to the cell edge improve the EE-SE optimal point. Moreover, better EE-SE tradeoff can be achieved with higher outage values. Besides, FRF of 1 is the best choice for very high outage value due to the significant signal-to-interference-plus-noise ratio (SINR) decrease.In downlink, precoders are used in space division multiple access (SDMA) MU-MISO cellular networks to improve the SINR. Stochastic geometry has been intensively used to analyse such a complex system. A closed-form expression for ASE in asymptotic regime, i.e. number of antennas and number of users grow to infinity, has been derived using random matrix theory and stochastic geometry. BSs and users are modeled by two independent PPP and SLNR precoder is used at BS. EE is then derived from a linear power consumption model. Monte Carlo simulations show that the analytical expressions are tight even for moderate number of antennas and users. Moreover, the EE-ASE curves have a large linear part before a sharply decreasing EE, as observed for hexagonal network. The results also show that SLNR outperforms the zero-foring (ZF) precoder, which is typically used in literature. Numerical results for SLNR show that deploying more BS or a large number of BS antennas increase ASE, but the gain depends on the BS-user density ratio and on the number of antennas when user density is fixed. EE increases only when the increase in ASE dominates the increase of the power consumption per unit area. On the other hand, when the user density increases, ASE in interference-limited region can be improved by deploying more BS without sacrificing EE and the ergodic rate of the users

Maintenir un accroissement soutenu de la valeur pour les actionnaires estaujourd'hui reconnu comme un des principaux objectifs stratégiques pour les institutions financières. Générer une croissance stable de la valeur pour les actionnaires nécessite une concentration intense sur une prestation de services de meilleure qualité aux clients, le recrutement, le maintien d'un effectif motivé, et l'entretien d'excellentes relations avec les différents partenaires de la firme bancaire.Cette thèse présente une évaluation analytique de la création de la valeur actionnariale dans le secteur bancaire. La première partie : Fournit un cadre pour l'analyse théorique de la valeur actionnariale en discutant comment la valeur actionnariale peut être définie, si elle peut être considérée comme un objectif valable et stratégique pour la banque, comment la valeur actionnariale peut être mesuré et comment elle peut être créé. La deuxième partie de la thèse présente des Investigations empiriques afin de mesurer la valeur actionnariale et certains de ses déterminants. La partie finale Analyses l'importance de Ces facteurs dans lacréation de valeur pour les actionnaires.L'échantillon utilisé comprend les dix banques tunisiennes cotées sur la bourse des valeurs mobilières de Tunisie entre 1995 et 2009. Nous utilisons un modèle de panel pour examiner les déterminants de la création de valeur pour les actionnaires (Mesuré par l'EVA et ses composante, c.-à-d. profits économiques et coût de capital) comme une fonction linéaire de variables spécifique aux banques et a l?industrie bancaire et des variables macro-économique. Nous trouvons que Divers facteurs semble être d'importants déterminants significatifs des profits économiques et de la valeur actionnariale créée par les banques. En cohérence avec la littérature antérieure, nous avons des efficiences coût et revenu qui sont liées positivement à la performance des banques: à savoir, les profits économiques ont eu un lien positif avec l'amélioration de l'efficience revenu, tandis que l'EVA est positivement liée a l'amélioration de l'efficience coût. Deuxièmement, nous trouvons une relation positive entre les pertes de crédit et la valeur actionnariale, ce qui explique que des pertes élevées inattendues impliquent un plus grand volume d'affaires et peut-être de moins bonne qualité du portefeuille de prêts. Troisièmement, nous avonsobservé un lien positif entre l'endettement bancaire et les profits économiques, mais non pas avec l'EVA. Cela est dû à la relation positive entre effet de levier financier et le coût du capital. Dans l'ensemble, plus le levier financier est important plus les profits économiques seront aussi importantes, mais cela est compensé par des coûts du capital plus élevés
Creating sustainable shareholder value is at this time accepted as one of the mostimportant strategic objectives for financial institutions. Generating stable shareholder value growth requires an intense focus on delivering benefits to customers in the most efficient way, hiring and retaining motivated personnel, maintaining excellent relationship with other firm stakeholders.This thesis provides an analytical assessment of shareholder value creation in banking. The first part of the text provides a framework for analysing shareholder value theory by discussing how shareholder value can be defined, if it can be considered a valid strategic objective for banks, how shareholder value can be measured and how it can be created.The second part of the text presents empirical investigations in order to measureshareholder value and some of it drivers. The final part analyses the importance of these drivers in creating shareholder value. In order to have a broad view of the sector, the sample analysed comprises commercial Tunisian banks listed on Tunisian stock exchange between 1995 and 2009. We use a panel model to examine the determinants of bank's shareholder value reaction (measured by EVA and its components) as a linear function of various bank-specific, industry-specific and macroeconomic. We find that various factors are found to be statistically significantdeterminants of economic profits and shareholder value created by banks. Consistently with the previous literature, we find that cost and revenue efficiency are positively related to bank performance: namely, economic profits are found to have a positive link with revenue efficiency improvements, while EVA is positively related to cost efficiency improvements. Secondly, we find a positive relationship between credit losses and shareholder value providing evidence that higher unexpected losses imply larger business volume and perhaps lower loan portfolio quality. Thirdly, we observe a positive link between bank's leverage and economic profits, but not with EVA. This is due to the positive relationship between financial leverage and the cost of capital, overall, greater financial leverage increase economic profits but this is compensate by higher costs of capital

Can statistical analysis of professional basketball players lead to a more efficient evaluation of a player's worth? Following the recent success of statistic-driven baseball franchises, many basketball executives and followers are beginning to mine the sport's production in search of an all-encompassing player value rating. Teams could thus exploit undervalued players, leading to increased team and fan welfare. My thesis addresses this ongoing debate by examining various player and team statistics in the National Basketball Association (NBA). While I find significant relationships between individual efficiency statistics and team success, I also discover the paramount importance of defensive statistics and balanced team payrolls. This paper proposes a model that would help team executives find players who promote team efficiency, rather than individual production

Detta examensarbete har utförts på Almroths Åkeri AB i Norrköping. Almroths är ett tredjepartslogistikföretag som inriktar sig på service inom lager och transport såväl som helhetslösningar skräddarsydda för att erhålla en god servicenivå mot slutkund. Stora krav ställs därför på effektiva flöden och hantering av artiklar på lagret. Fokus i detta arbete har koncentrerats på Almroths kund Garden Girl, som säljer trädgårdsartiklar av varierat sortiment med en säsongsbetonad försäljning. Almroths lagerhåller Garden Girls artiklar innan vidare leverans sker mot slutkund. Syftet med detta examensarbete är att effektivisera Almroths verksamhet med hänsyn till plockning av artiklar genom en förbättrad artikelplacering för kunden Garden Girl. Utifrån Almroths affärssystem innehållande artikeldata över Garden Girls efterfråga har en ABC-klassificering genomförts. Denna klassificering ska generera en placering för Garden Girls artiklar som minskar plocktiden. Observationer av Almroths lager har utförts för att kartlägga hur plockningen genomförs i nuläget. En mätning av plockmetoder har genomförts för att jämföra nulägets plockmetod med orderplockning, artikelplockning och zonplockning. Resultatet av ABC-klassificeringen utformas av ett Excelark innehållande en klassificering för samtliga artiklar som förekommer i Garden Girls sortiment. Dessa artiklar delas in i A, B och C klass (A är den grupp med högst antal artiklar placerade i en order) beroende på hur många gånger en artikel plockas. Klass A i ABC-klassificeringen består av artiklar som lagts i en order mellan 36-24 gånger, klass B artiklar mellan 24-7 gånger och klass C artiklar mellan 7-1 gång. Med detta menas att artiklarna i klass A kommer placeras närmst plockcentralen, klass B artiklar därefter och längst ifrån plockcentralen placeras klass C artiklar. Resultatet för mätningen av plockmetoder visade på att orderplockning med två order är den metod som anses effektivast tidsmässigt för Garden Girls artiklar. Vid mätningen framkom att plockning med totalt 100 artiklar kunde generera en tidsbesparing på upp till sju minuter alternativt 30 % med plockmetoden orderplockning om två order plockas parallellt jämfört med en order åt gången. Rekommendationerna gruppen ger till Almroths är att utifrån ABC-klassificeringen, arrangera om Garden Girls artiklarna efter det resultat som tagits fram. Även trots att omplaceringen kräver mycket tid och kapacitet anser gruppen det kommer bli en besparing i framtiden. Avslutningsvis föreslår gruppen att Almroths ska bibehålla sin nuvarande plockmetod orderplockning, med två eller tre order.
