Book excerpt: Le développement des technologies de l'information et de la communication que connait notre siècle a grandement facilité les pratiques d'échanges d'informations au sein des chaînes logistiques. Ces pratiques ont pu ainsi évoluer vers de nouvelles formes de collaborations entre entreprises, telles que le Partage d'Informations (PI) et le Vendor Managed Inventory (VMI). Le VMI est un mécanisme de coordination dans lequel le fournisseur a la responsabilité de la gestion des stocks de son client. Ce mécanisme repose sur plusieurs principes parmi lesquels un partage d'informations très développé entre les parties qui s'y engagent. Le PI et le VMI sont adoptés par les entreprises pour permettre une augmentation des profits et une réduction des coûts. Toutefois, leurs résultats sont mitigés et nécessitent encore un approfondissement de leur compréhension. La contribution de cette thèse se situe dans l'analyse des impacts de ces mécanismes sur des chaînes logistiques où tous les maillons sont des entreprises de production dont les efficacités peuvent être différentes. Pour ce faire, plusieurs scénarios ont été étudiés sur des chaînes logistiques constituées de trois échelons, chaque échelon peut appartenir à quatre classes d'efficacité. Ces chaînes peuvent répondre à deux types de demande du marché final ; une demande stable ou une demande variable. De plus, plusieurs mécanismes de coordination sont étudiés : les mécanismes de gestion standard, de partage d'informations entre deux échelons, de partage d'informations entre trois échelons, de VMI entre deux échelons, puis de VMI étendu aux trois échelons. L'outil utilisé pour mener ces expérimentations est le logiciel de simulation à évènements discrets Arena. L'interprétation des résultats a montré que le mécanisme de coordination avec partage d'informations n'a pas eu d'amélioration très significative sur les résultats. En effet, puisque les entreprises ont des capacités de production finies, la disponibilité de l'information n'a pas permis d'obtenir des résultats différents. Le VMI, de son côté, a pu réaliser des réductions des stocks et des coûts de la chaîne logistique. Ces réductions ont été plus importantes chez les chaînes logistiques dont les maillons sont de faibles efficacités. Chez ces dernières, ce sont les deux parties concernées par le VMI (le fournisseur et le donneur d'ordres) qui ont tiré des avantages du VMI. Chez les chaînes logistiques constituées de maillons de haute efficacité, le VMI a permis une réduction des coûts moins importante, car ces chaînes logistiques sont déjà de performance élevée. Pour celles ci, c'est le client qui a tiré profit du VMI, alors que le fournisseur VMI a subi une augmentation des coûts suite à l'augmentation de la fréquence de transport qu'a impliqué ce mécanisme.

Book excerpt: Cette recherche porte sur l'étude de l'impact du partage de plusieurs informations simultanément dans différentes configurations de chaînes logistiques. Celui-ci s'exprime en termes de réduction du coût logistique par rapport au scénario de non partage d'informations et est évalué au niveau de la chaîne logistique dans sa globalité, mais également au niveau de chaque coût élémentaire de chaque maillon. Le choix des informations partagées est basé sur leur importance dans la gestion de la chaîne logistique ainsi que sur leur provenance (amont et aval) pour permettre d'instaurer des mécanismes d'échange et de négociation entre les différents maillons. Notre approche est développée dans le cadre d'une chaîne logistique série mono-produit composée d'un fournisseur, d'un entrepôt, d'un détaillant et de clients. Nous avons développé un modèle mathématique permettant l'évaluation des gains de ce partage d'informations dans le cadre d'une décision décentralisée. Ce premier modèle nous a permis d'étudier les impacts du partage de ces informations dans des circonstances proches de la réalité suite à l'injection de perturbations même dans le cas de partage. L'étude expérimentale réalisée a permis de mettre en évidence la nécessité de mettre en place des mécanismes incitatifs de coopération entre les différents maillons de la chaîne logistique lorsque les gains ne bénéficient de manière quasi exclusive qu'à un seul des maillons ou s'avèrent particulièrement déséquilibrés, mécanismes visant à aboutir à des équilibres gagnant-gagnant entre les participants. Nous avons ensuite considéré le cas d'une décision décentralisée avec partage de deux informations simultanément. Cette partie de notre travail est réalisée sur une chaîne logistique divergente mono-produit intégrant plusieurs détaillants. L'affectation par l'entrepôt des produits aux détaillants est réalisée au prorata des commandes détaillants. Nous avons proposé de mettre en place des mécanismes de coopération nécessaires pour garantir un gain équilibré entre les différents maillons dans les différents scénarios de partage. Nous avons considéré par la suite une décision centralisée au niveau de l'entrepôt avec une affectation de produits minimisant le coût logistique de toute la chaîne. Pour terminer, notre approche a été étendue à l'étude de la répartition des gains entre détaillants dans différentes configurations de demande et ce dans les différents scenarii étudiés. Ceci nous a permis d'identifier les bénéficiaires de ce partage d'informations dans différents contextes. Nous avons conclu par le fait qu'une décision décentralisée avec partage d'informations est proche en termes de performance de celle obtenue dans un contexte centralisé et préconisé de poursuivre cette étude comparative en prenant en compte l'ensemble des coûts et bénéfices de ces deux modes de pilotage.

Book excerpt: Vendor-managed inventory (VMI) and consignment inventory (CI) are supply-chain sourcing practices between a vendor and customer. VMI allows the vendor to initiate orders on behalf of the customer. This presumably benefits the vendor who can then make replenishment decisions according to her own preferences. In CI, as in the usual independent-sourcing approach to doing business, the customer has authority over the timing and quantity of replenishments. CI seems to favor the customer because, in addition, he pays for the goods only upon use. Our main aim is to analyze CI in this supply chain under deterministic demand, and provide some general conditions under which CI creates benefits for the vendor, for the customer, and for the two parties together. We also consider similar issues for the combined use of CI and VMI.

Available in PDF, EPUB and Kindle. Book excerpt: Dans cette thèse, nous nous sommes intéressés à l’examen de la valeur d'information relative au délai d’approvisionnement dans les centres de distribution. Nous avons proposé une démarche de résolution en six étapes et ensuite nous avons développé un premier modèle de simulation paramétrable qui s’appuie sur cette démarche de résolution proposée. Ce modèle de simulation nous a permis de réaliser une première analyse numérique s’appuyant sur une structure de dépôt. Dans la suite de cette recherche, nous avons étudié un entrepôt avec plusieurs détaillants. Pour ce problème, nous avons d’abord formulé un modèle de stockage avec délai d’approvisionnement aléatoire. En appliquant successivement deux politiques de stockage, nous avons distingué deux modèles de base : un premier modèle dans le cas de partage d’information et un second pour le cas de non partage d’information. Nous avons programmé les deux modèles dans l’environnement LINGO. Les résultats de ces deux études théoriques montrent : - Le partage d’information de délai a des impacts importants ; - Des relations importantes entre la valeur du partage d’information et plusieurs d’autres éléments : le mode de coopération, le contexte du marché, le comportement clientèle, le coût unitaire de rupture, la structure de réseau et les caractéristiques du délai ; - Le comportement clientèle ressort comme étant le facteur le plus important en termes de sensibilité sur la valeur du partage et aussi sur l’effet des autres paramètres ; A la fin, pour valider les résultats issus des études théoriques, on a modélisé et étudié l'effet du partage d’information dans une chaîne logistique pharmaceutique aval.

This book was released on 2006 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study investigates the impacts of four advanced coordination mechanisms on supply chain performance under different operational and environmental conditions. Compared with the traditional supply chain system, consignment, two variants of vendor managed inventory (VMI I, VMI II) systems, and collaborative planning, forecasting and replenishment (CPFR) are considered to be advanced coordination mechanisms. They have been advocated in the past due to the efficiency that they may bring through joint decision making and information sharing, which may ultimately result in improved supply chain performance. Analytical modeling based on cost minimization and profit maximization problems is first applied to make the direct comparison of coordination mechanisms with the traditional system. In order to conduct additional sophisticated analyses, this study applies simulation modeling based on time-phased operations, as in materials requirements planning (MRP) systems. A two-stage supply chain system, with a single buyer and a supplier, is considered and it incorporates multiple steps of operations including forecasting, replenishment, inventory management, production, and transportation. The simulation models consider six operational and environmental factors: coordination mechanism, information sharing, demand pattern, lead time, production capacity, and cost structure. The performance of each supply chain system is evaluated in terms of service levels, bullwhip effect, and profits of the buyer, the supplier, and the whole supply chain. The outcomes of simulation runs are statistically analyzed by comprehensively using multi-variate analysis of variance (MANOVA) and analysis of variance (ANOVA). The simulation results generally support the widely held view that more advanced coordination mechanisms have greater supply chain profit than less advanced ones. On the other hand, advanced coordination mechanisms like CPFR do not necessarily improve customer service level and bullwhip effect. VMI I was found to result in good performance in terms of supplier's service level (fill rate) and bullwhip effect. Information sharing does not only increase the supply chain profit, but also is required for the coordination mechanisms to achieve improved performance. Further properties of coordination mechanisms are analyzed and discussed.

Book excerpt: How logistics clusters can create jobs while providing companies with competitive advantage. Why is Memphis home to hundreds of motor carrier terminals and distribution centers? Why does the tiny island-nation of Singapore handle a fifth of the world's maritime containers and half the world's annual supply of crude oil? Which jobs can replace lost manufacturing jobs in advanced economies? Some of the answers to these questions are rooted in the phenomenon of logistics clusters—geographically concentrated sets of logistics-related business activities. In this book, supply chain management expert Yossi Sheffi explains why Memphis, Singapore, Chicago, Rotterdam, Los Angeles, and scores of other locations have been successful in developing such clusters while others have not. Sheffi outlines the characteristic “positive feedback loop” of logistics clusters development and what differentiates them from other industrial clusters; how logistics clusters “add value” by generating other industrial activities; why firms should locate their distribution and value-added activities in logistics clusters; and the proper role of government support, in the form of investment, regulation, and trade policy. Sheffi also argues for the most important advantage offered by logistics clusters in today's recession-plagued economy: jobs, many of them open to low-skilled workers, that are concentrated locally and not “offshorable.” These logistics clusters offer what is rare in today's economy: authentic success stories. For this reason, numerous regional and central governments as well as scores of real estate developers are investing in the development of such clusters.

Book excerpt: Industrial revolutions have impacted both, manufacturing and service. From the steam engine to digital automated production, the industrial revolutions have conduced significant changes in operations and supply chain management (SCM) processes. Swift changes in manufacturing and service systems have led to phenomenal improvements in productivity. The fast-paced environment brings new challenges and opportunities for the companies that are associated with the adaptation to the new concepts such as Internet of Things (IoT) and Cyber Physical Systems, artificial intelligence (AI), robotics, cyber security, data analytics, block chain and cloud technology. These emerging technologies facilitated and expedited the birth of Logistics 4.0. Industrial Revolution 4.0 initiatives in SCM has attracted stakeholders’ attentions due to it is ability to empower using a set of technologies together that helps to execute more efficient production and distribution systems. This initiative has been called Logistics 4.0 of the fourth Industrial Revolution in SCM due to its high potential. Connecting entities, machines, physical items and enterprise resources to each other by using sensors, devices and the internet along the supply chains are the main attributes of Logistics 4.0. IoT enables customers to make more suitable and valuable decisions due to the data-driven structure of the Industry 4.0 paradigm. Besides that, the system’s ability of gathering and analyzing information about the environment at any given time and adapting itself to the rapid changes add significant value to the SCM processes. In this peer-reviewed book, experts from all over the world, in the field present a conceptual framework for Logistics 4.0 and provide examples for usage of Industry 4.0 tools in SCM. This book is a work that will be beneficial for both practitioners and students and academicians, as it covers the theoretical framework, on the one hand, and includes examples of practice and real world.

This book was released on 2020-10-14 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the current urbanization trend, there is an increased need for city development, i.e. to build apartment buildings, hospitals, schools and infrastructure in cities and urban areas to meet the rising demands. At the same time, land is increasingly seen as a finite resource. This has led to the regeneration of decommissioned industrial-use land for development purposes. This means that multiple individual construction projects are being built in the same or nearby areas during the same time-period. However, the end products of construction projects are produced at their place of consumption, which means that large quantities of materials and resources need to be delivered to, and removed from, each construction site. This leads to new transport flows being created in connection to city development. These transport flows need to be coordinated to ensure efficient construction productivity and reduce the transports’ environmental and social impact on the urban transport system. At the same time, it is important to ensure that construction sites can be managed from a logistics perspective without impairing efficiency due to the challenges of building in urban environments. One way of managing logistics to and from construction projects in city development is through so-called construction logistics setups (CLS). However, the implementation of CLS’s affect many different stakeholders and the interorganizational relationships between them. The implementation of CLS’s therefore faces three challenges; management of transport to and from construction sites, management of logistics at construction sites, and managing the interorganizational relationships amongst construction project stakeholders. The development of CLS’s is often undertaken by mimicking previous setups as there is currently no guiding procedure for developing and implementing CLS’s. To reduce the ad hoc approach to developing and implementing CLS’s, the purpose of this dissertation is to propose a framework for developing construction logistics setups. The purpose is fulfilled with the aid of the following four research questions: RQ1: Taking the perspectives of different stakeholders’, why are CLS’s implemented? RQ2: What type of CLS services are offered? RQ3: How can performance effects of CLS’s be measured? RQ4: How do CLS’s affect the identified challenges of managing the transports to and from construction sites, managing logistics at construction sites, and managing the interorganizational relationships amongst construction project stakeholders? To answer the research questions, three main methodologies have been used; literature reviews to inform the background of the studies and develop analytical frameworks, and case study and Delphi research for the empirical studies. In fulfilling the research purpose, the findings of this dissertation suggests that when developing a CLS, three activities need to be considered; 1. setting the scope of the CLS, 2. deciding on the structure of the CLS, and 3. managing the interorganizational relationships of the CLS. These activities are the foundation of the developed framework. The contents of the activities were derived through the research questions. When answering RQ1, it was found that contractors implement CLS’s to ensure construction productivity, developers implement CLS’s to reduce disturbances to businesses and residents nearby, and municipalities implement CLS’s to reduce disturbances to third-parties and to reduce the impact from construction logistics on the urban transport system. These stakeholder drivers for implementing CLS’s will impact the scope of the CLS. Furthermore, the scope of the CLS was found to be dependent on both the contextual considerations of the CLS in terms of physical context at site and in terms of what is being built, as well as the organizational context in terms of what stakeholders are part of the project, where in the hierarchy the CLS is located, and what level of mandate the CLS has. The scope will also set the terms for how transports are managed through the CLS. If for instance there is limited space at site, this can imply that time-planned deliveries are favoured. In answering RQ2, it was found that as a consequence of what transport management approach is chosen, the structure of the CLS will differ. This dissertation shows that asset-based setups are similar to traditional logistics outsourcing and TPL in which physical distribution services are offered. Non-asset based services on the other hand act more as supply chain orchestrators similar to fourth-party logistics service providers. In these cases, supplied services are aimed more at ensuring that the right services and capabilities can be procured for the CLS. One value-adding service that was found crucial to include in CLS’s is a joint booking and planning system. Having this type of support systems will allow the CLS to coordinate the different stakeholders connected to the CLS. Related to the structure of the CLS, RQ3 suggest that performance needs to be monitored for deliveries, on-site logistics, and the coordination of logistics activities on and off site. The performance monitoring needs to be developed from a logistics point-of-view, taking into consideration the different stakeholders’ perspectives. Finally, in answering RQ4, it was found that a CLS can affect the identified challenges positively. In essence, a CLS aims at managing construction logistics and if developed and implemented from this notion, transports to and from site as well as on-site logistics management can become more efficient. Additionally, the dissertation shows that CLS’s can help in managing the interorganizational relationships within the construction project(s). However, this builds on the notion of having well-developed and communicated service offerings and regulations, e.g. through business and governance models. It was also found that the activities of the framework are interrelated and dependent on one another, suggesting that developing construction logistics setups is an iterative process. The proposed framework should thus be seen as a guideline for how to develop the setup, allowing for adaptations of the setup to the context for which it is developed. Med pågående urbaniseringstrend finns det ett ökat behov av att bygga bostadshus, sjukhus, skolor och infrastruktur i stadsområden för att möta de ökande behoven. Samtidigt ses mark allt mer som en ändlig resurs. Detta har lett till att avvecklad industriell mark tas i anspråk för förtätning och storskaliga stadsutvecklingsprojekt där flera enskilda byggprojekt byggs i närliggande områden under samma tidsperiod. Byggprojekt produceras dock på konsumtionsplatsen vilket innebär att stora mängder material och resurser måste levereras till och tas bort från varje byggarbetsplats. Detta leder i sin tur till att nya transportflöden skapas i samband med stadsutveckling. Dessa måste samordnas för att säkerställa effektiv byggproduktion samtidigt som transporternas miljömässiga och sociala påverkan på det urbana transportsystemet kan minskas. Samtidigt är det viktigt att byggarbetsplatserna kan hanteras ur ett logistikperspektiv utan försämrad effektivitet på grund av det urbana läget. Ett sätt att hantera logistiken till och från byggprojekt inom stadsutveckling är genom så kallade bygglogistiklösningar (BLL). Dock påverkar införandet av BLL många olika intressenter och de interorganisatoriska relationer dem emellan. Införandet av BLL ställs därför inför tre utmaningar; att hantera transporter till och från byggprojekt, att hantera logistiken på byggarbetsplatser och att samordna de interorganisatoriska relationerna mellan byggprojektets intressenter. Utvecklandet av BLL utgår ofta från tidigare lösningar då det i nuläget saknas riktlinjer för hur man kan utveckla och implementera lösningarna. För att minska den här ad hoc-strategin för utvecklandet av BLL är syftet med denna avhandling att föreslå ett ramverk för att utveckla bygglogistiklösningar. Syftet uppnås med hjälp av följande forskningsfrågor: FF1: Utifrån olika intressenters perspektiv, varför implementeras bygglogistiklösningar? FF2: Vilken typ av bygglogistiktjänster erbjuds? FF3: Hur kan bygglogistiklösningars prestanda mätas? FF4: Hur påverkas de tre identifierade utmaningarna av implementeringen av bygglogistiklösningar? Hur påverkar bygglogistiklösningar de identifierade utmaningarna med att hantera transporter till och från byggprojekt, att hantera arbetsplatslogistiken och att samordna de interorganisatoriska relationerna mellan byggprojektets intressenter? För att besvara forskningsfrågorna har tre huvudmetoder använts; litteraturgranskningar för studiernas bakgrund och att utveckla analytiska ramverk, och fallstudieforskning och Delphi-forskning för de empiriska studierna. I uppfyllandet av syftet föreslår avhandlingen att tre aktiviteter måste övervägas när man utvecklar en BLL; 1. fastställa omfattningen av BLL, 2. besluta om BLL-strukturen och 3. hantera interorganisatoriska relationerna i BLL. Dessa aktiviteter är grunden för det utvecklade ramverket. Innehållet i aktiviteterna härleddes genom forskningsfrågorna. I besvarandet av FF1 befanns att entreprenörer implementerar BLL:er för att säkerställa byggproduktivitet, byggherrar implementerar BLL:er för att minska störningar för företag och boende i närheten, och kommuner implementerar BLL:er för att minska störningar för tredje part och för att minska påverkan från bygglogistik på det urbana transportsystemet. De identifierade drivkrafterna för att implementera BLL:er kommer även att påverka BLL:ens struktur. Avhandlingen visar att BLL-strukturen är beroende av kontextuella överväganden med avseende på arbetsplatsens fysiska egenskaper samt vad som byggs, såväl som den organisatoriska kontexten med avseende på vilka intressenter som är del av projektet, var i hierarkin BLL:en placeras och vilken mandatnivå BLL:en har. BLLomfattningen sätter även villkoren för hur transporter hanteras i projektet. Om utrymmet exempelvis är begränsat kan detta innebära att tidsplanerade leveranser premieras. I besvarandet av FF2 befanns det att en konsekvens av hur transporthanteringen läggs upp så kommer BLL-strukturen att påverkas. Den här avhandlingen visar att fysiska logistiklösningar liknar traditionell outsourcing av logistik och TPL där fysiska distributionstjänster erbjuds. Icke-fysiska logistiklösningar fungerar mer som försörjningskedjeorkestratorer och påminner om fjärdepartslogistiktleverantörer. I dessa fall syftar de erbjudna tjänsterna mer till att säkerställa att rätt tjänster och kapacitet kan erbjudas genom BLL. En värdeadderande tjänst fanns vara en grundförutsättning för BLL:er, nämligen gemensamma boknings- och planeringssystem. Ett sådant system hjälper BLL-operatören i koordinationen av de olika intressenterna som är kopplade till BLL:en. I framtagandet av BLL-strukturen föreslår FF3 även att logistikprestanda måste följas upp i processerna leveranser, arbetsplatslogistik och samordning av logistikaktiviteter på och utanför byggarbetsplatsen. Prestationsutvärderingen måste utvecklas ur ett logistikhänseende med hänsyn tagen till de olika intressenternas perspektiv. Slutligen, i besvarandet av FF4, befanns att en BLL kan påverka de identifierade utmaningarna positivt. I grund och botten syftar en BLL till att hantera bygglogistik och om BLL:en utvecklas och implementeras utifrån detta synsätt kan transporter till och från byggarbetsplats samt logistikhantering på plats bli effektivare. Vidare visar avhandlingen att BLL:er kan hjälpa till att hantera de interorganisatoriska relationerna inom byggprojekten. Detta bygger dock på att man har väl utvecklade och kommunicerade serviceerbjudanden med tillhörande regelverk för hur service skall användas. Dessa bör kommuniceras genom affärs- och styrningsmodeller. Det konstaterades också att ramverkets aktiviteter är inbördes relaterade och beroende av varandra, vilket tyder på att utvecklandet av bygglogistiklösningar är en iterativ process. Det föreslagna ramverket bör därför ses som riktlinjer för hur man utvecklar BLL, vilket möjliggör för anpassningar av lösningen till det sammanhang för vilken den utvecklas.

Available in PDF, EPUB and Kindle. Book excerpt: Construction, architecture and engineering projects are complex undertakings, involving a temporary grouping of people and companies, with different agendas and experience, coming together to achieve a project goal. This book investigates the dynamics of the relationships between individuals involved in architecture, engineering and construction projects. It combines a structured theoretical framework, derived from social psychology and mainstream management theory, with case studies and research from the built environment sector. Focusing on how people interact, communicate and work together, it examines how best to manage the interdisciplinary relationships that form and reform during the project life cycle. The book covers vital areas of project management, whose importance has recently come to be recognized, and will be valuable for students at both undergraduate and graduate level. Practitioners will also find it a useful insight into the social aspect of project management, with implications and applications that apply to all projects in the built environment sector.
