Nguyen, Thi Thu Tam. „Learning techniques for the load forecasting of parcel pick-up points“. Electronic Thesis or Diss., université Paris-Saclay, 2023. http://www.theses.fr/2023UPASG034.
Der volle Inhalt der QuellePick-Up Points (PUP) represent an alternative delivery option for purchases from online retailers (Business-to-Customer, B2C) or online Customer-to-Customer (C2C) marketplaces. Parcels are delivered at a reduced cost to a PUP and wait until being picked up by customers or returned to the original warehouse if their sojourn time is over. When the chosen PUP is overloaded, the parcel may be refused and delivered to the next available PUP on the carrier tour. PUP load forecasting is an efficient method for the PUP management company (PMC) to better balance the load of each PUP and reduce the number of rerouted parcels. This thesis aims to describe the parcel flows in a PUP and to proposed models used to forecast the evolution of the load. For the PUP load associated with the B2C business, the parcel life-cycle has been taken into account in the forecasting process via models of the flow of parcel orders, the delivery delays, and the pick-up process. Model-driven and data-driven approaches are compared in terms of load-prediction accuracy. For the PUP load associated with the C2C business, the daily number of parcels dropped off with a given PUP as target is described by a Markov-Switching AutoRegressive model to account for the non-stationarity of the second-hand shopping activity. The life-cycle of each parcel is modeled by a Markov jump process. Model parameters are evaluated from previous parcel drop-off, delivery, and pick-up records. The probability mass function of the future load of a PUP is then evaluated using all information available on parcels with this PUP as target. In both cases, the proposed model-driven approaches give, for most of the cases, better forecasting performance, compared with the data-driven models, involving LSTM, Random forest, Holt-Winters, and SARIMA models, up to four days ahead in the B2C case and up to six days ahead in the C2C case. The first approach applied to the B2C parcel load yields an MAE of 3 parcels for the one-day ahead prediction and 8 parcels for the four-day ahead prediction. The second approach applied to the C2C parcel load yields an MAE of 5 parcels for the one-day ahead prediction and 8 parcels for the seven-day ahead prediction. These prediction horizons are consistent with the delivery delay associated with these parcels (1-3 days in the case of a B2C parcel and 4-5 days in the case of a C2C parcel). Future research directions aim at optimizing the prediction accuracy, especially in predicting future orders and studying a load-balancing approach to better share the load between PUPs

Der volle Inhalt der QuelleTravelling post offices, mail-sorting services aboard trains, first appeared in the nineteenth century. The french name for these units, ambulants postaux, refers to both the service and the people who work in it. With time, they became one of the key fixtures, in mail routing and in the public-service structure of the french post office, where their presence led to more widespread access for the public. Employees in these units where working conditions were labelled unhealthy sought to improve their lot by joining the same unions as privates-sector workers and by demanding contracts in order to clarify their ties with the state. The recognition of their collective representaion brought them new rights, when the right of civil servants to unionize was granted, in 1946, while retaining a certain autonomy, particularly around the organization of shift-work and compensatory reduction of overall working hours. Starting in the late sixties, the role of the travelling post

Der volle Inhalt der QuelleThis thesis is aimed at proposing a definition of the public service in the history of the mail Postal Office, between the Revolution and the liberal turning point of the second Empire. This work is based on a number of indications stemming trom elements that constitute the definition of the public service during the 19th century, that is to say, the structure, the aim of the service, the appropriate legal system. In other words, the point is to analyse how the postal administration evolves towards the notion of public service, and how this notion questions itself and becomes operative in the postal field. The research study during the envisaged time trame has highlighted two major periods in this contribution to the history of the postal public service. From the Revolution to the Empire, the first objective for the postal administration, is to outlive an adverse climate, while the highly polysemous notion of public service is trequently debated during parliamentary sessions. The postal administration stabilizes under the Empire regime. From the "Restauration" to the liberal turning point of the second Empire, the notion of the public service gains ground as the mail Postal Office evolves. If its influence is no more than unofficial, the speeches and the interventions about the graduai improvements brought to the postal service create a link between the monopole that the State exploits, the geographic and financial access to the service, the social function and the public service. Concurrently, during the second half of the 19th century, the courts more and more refer to the public service

Der volle Inhalt der QuelleIn chapter one, we investigate the consumers' preferences for various kinds of postal services. As such, we begin by reviewing the market and regulatory conditions for Europe and for our case study, Belgium. Then using data provided by the incumbent provider, the Belgian post (Bpost), we estimate demand price elasticities. The data comprises customer transactional information on letter mail, direct mail, parcels & express services, press delivery and value added services for the 2008-2009 period. These categories constitute not only the important lines of services that Bpost offers to its clients but also the main segments that constitute the whole Belgian postal market. As such, and using standard methods, we estimate for each service an equation that explains demand by prices, product varieties (i.e. mixes or combinations of volume, weight, priority and destination, inter alia), income, regulation proxies and other socioeconomic variables. The estimated price elasticities for regulated and partially regulated services are around -1.1, whereas for unregulated segments they fluctuate between -2.1 and -2.8. The lowest price elasticity is obtained for direct mail services (-1.0); the highest ones are associated with value added services (-2.1) and registered mail (-3.3). Price elasticities may be influenced by the cyclical effects during the period of analysis. Therefore, elasticities are higher when compared with the empirical evidence obtained for other countries and through the various methodologies applied over the last decades. The fact that technological substitutes, such as expenditures on telephony and internet access for daily and administrative mail services and, radio and television advertising for direct mail services, could not be accounted for (because there were no data available) may however be considered as a major limitation for the scope of our results.
In the second chapter, we explore theoretically the effects of the USO on unregulated markets. In particular, we are interested in investigating its welfare effects when the provision of services cannot be technologically separated. We present a model in which there is an incumbent who provides two services: a universal service and a non-USO service, the latter opened to competition. This is the case of letter mail and direct (or bulk) mail, services which have quite different purposes and regulatory frameworks (i.e. the former is fully regulated whereas the latter is liberalized under the current European Internal Market framework), but are jointly produce at some stages of the postal value chain. The USO is simplified to two dimensions, affordability and quality, implemented as a price cap and a minimum quality standard (MQS) for the provision of letter mail services. The latter involves the technological aspects that we are interested in. We find that the definition of the USO plays an important role in organizing markets that are open to competition. When it imposes few quality requirements (low MQS), the incumbent is not cost efficient enough to provide the high-quality variant of bulk mail, allowing its competitors to cream-skim the segment. However, because there are cost economies, the firm's participation in the segment yields a higher average quality of mail services at lower prices. When the USO is too comprehensive (high MQS), the incumbent exhibits large cost economies that ensure a dominant position in the provision of bulk mail services. Consumers are worse off as competition induces too much service differentiation in order to make profitable the provision. Relaxing the definition of the USO mitigates the competitive advantage of the USP and so, yields improvements in welfare. In the absence of access costs, firms will find profitable to participate in the bulk mail segment. However, foreclosure happens if the USO induces the incumbent to exhibit significant fixed costs. Therefore, the USP may end up as the sole supplier of bulk mail services if the definition of the USO imposes too many quality requirements (high MQS). In that case, the authority must balance the welfare gains of defining USO with the welfare losses of the consumers of the contested service.
Finally, in the third chapter we consider the ownership aspect of the provision of universal services as an incentive to introduce competition. One can further segment the provision between services for customers located in high-cost areas and services for customers located in low-cost areas. Additionally, under the current EU legislation, the supply is divided between upstream activities (e.g. collection and sorting) and downstream activities (i.e. delivery). The provision of upstream activities in high-cost areas remains in hands of the incumbent firm or the owner of the downstream (delivery) network. The upstream provision in low-cost areas is open to competition, but a retailer may be vertically integrated/separated or legally unbundled with the downstream firm. Legal unbundling means, in our model, that the downstream firm and one upstream firm located in the low-cost area belong legally to the same entity entitled to all profits, whom does not have full control rights over the firms' decisions. That is to say, upstream activities and the downstream services will be managed separately under the same ownership. In this framework we analyze the firm's boundaries in terms of competition development and welfare. We implement two criteria to answer questions like, does vertical separation promotes competition (entry of firms) while covers a larger demand than vertical integration? Does vertical integration demand less public funds to cover demand? Does legal unbundling is worse than ownership separation to promote competition? The first criterion is the probability of entry (of the potential upstream firm), which we determine for each modes of ownership. The second criterion is the cost of public funds. It is implemented by defining a loss function as the difference between the expected consumer surplus when the downstream firm chooses an access fee that maximizes its profits and the consumer surplus when access is priced at marginal cost. The use of both criteria let us conclude that efficient entry occurs when the downstream firm is vertically separated or legally unbundled of the retailer providing services in the low-cost area. However, it is under legal unbundling that the access charge takes its lowest value. The highest cost of public transfers is obtained when firms are vertically separated, but the lowest one is attained when firms are legally unbundled. Therefore legal unbundling constitutes the preferred organizational form to induce competition and to reduce the cost of public funds.

Der volle Inhalt der QuelleThe postal market evolution leads to a process of deregulation by reason of national monopoly review and competition rules application. The external environment transformation was accompanied by the creation of a new regulation: the change of the post office status. This old administration, which turned a nationalized company, seems to be into a heterogeneous organization. The hybrid nature of the post office status is analyzed in this thesis: the new rules and the new game of this organization have been described. The new regulation understanding is based on the case of the delivery of letters. This economic thesis includes not only a sociological proceeding but also a juridical and historical analysis of the organization

Der volle Inhalt der QuelleElectricity is undoubtedly an indispensable resource for modern society. The same has revolutionized the way of life of the human being in all aspects and substantially improved their quality of life. The distribution of electricity is up to the Electric Power System - EPS, basically divided into three macro sectors: generation, transmission and distribution. Electricity is actually delivered to consumers by the distribution system, consisting mainly of overhead lines supported by pylons, these mostly made of reinforced concrete. Given the adequate supply of electricity to society, it is necessary to ensure the power distribution lines, in which the poles play a fundamental role. It is understood that increasing the useful life of reinforced concrete poles can contribute to the reduction of maintenance of the distribution network, reducing investment in replacements or repairs on poles by concessionaires. Thus, this paper proposes the optimal trait used in the production of reinforced concrete poles on a firm concrete artifacts, seeking the life of it For both studies were performed in order to improve the composition of households, adding pozzolanic material, adding fiber and use of superplasticizers additives. For analysis of traces in real scale 12 posts, T type double with 9 feet long, employing five traits were shaped with distinct characteristics. The posts were evaluated following the methodology and requirements of NBR 8451-1 (ABNT, 2011), the mechanical response of concrete and chloride ion penetration ASTM C1202 (2012). By analyzing the results, the dash indicated for production of reinforced concrete poles, where it was possible to improve the trace currently produced by the company, reducing the cement content of 429 kg / m³ to 351 kg / m³ and reducing the rate appears penetration of chloride ions and increasing the service life of reinforced concrete post 10 to 60 years. In view of this, it was possible to extend the life of the element, even with the reduction in cement consumption and the cost for the production of concrete mix.

Dans un second chapitre, nous étudions les prix de transfert utilisés pour valoriser les transactions entre une maison mere régulée et une filiale concurrentielle. nous présentons dans le détail l'affaire chronopost qui a donne naissance a la jurisprudence européenne en matiere de prix de transfert.
Dans un troisième et dernier chapitre, nous reprenons les thématiques des chapitres précédents et ajoutons la possibilité pour un operateur d'adopter des stratégies anticoncurrentielles. nous présentons l'exemple de la poste allemande condamnée pour avoir adopté une strategie prédatrice sur un segment de son marché colis. nous tentons alors de verifier la conjecture selon laquelle les entreprises régulées seraient plus susceptibles d'adopter des comportements prédateurs.

The latter, supposed in conformity with the right of the competition, reconcile obligations of public interest and methods resulting from the common right. However, the realization of these modes in national laws creates the conditions of a scaling. The legal status of the universal service evolves of a research of a legal balance to the modeling and the harmonization of a political balance between the interest of the Member States and that of the European Union

Der volle Inhalt der QuelleThis thesis retraces the origin of the financial advisor position at La Poste. It analyses the emergence of a commercial position within a rapidly changing State administration. La Poste became a public limited company in 2010; symbolically, La Banque Postale was authorised at the same time to provide credit to consumers. However, it was also required to guarantee a certain number of public service missions and to settle previous, unresolved administrative tensions that were affecting its staff on a daily basis. The aim of the professionalisation process analysed in this research was not, however, to transform the professional group into a profession. Ln that sense it may partly be considered atypical. Even though it brought together the functionalist charaeteristics of the Anglo-Saxon "profession" (Wilensky 1964), it did, in fact, aim to impact on staff, thereby constituting more of a strategy for avoiding resistance through regulating the professional group than an empowerment of that group (Boussard, Demazière, Milbum, 20 10). Yet this professionalism from above was intended to ease the tension experienced by staff that were given orders, which we shall labei "prescribèd" and contradictory. The issue was settled by means of organisational changes and the postal staffs "submission", which took place because of the process of professionalism from above (Evetts, 2003). To support this theory, I have based my research approach on qualitative, quantitative, ethnographic and archival methods that are interconnected. These different types of material have been drawn together in the context of a sociology of professional groups, with the aim of analysing the occurrences that take place at group level without losing sight of what is involved in work activity, while bearing in mind the particularities involved in carrying out that work (Demazière, Gadéa, 2009)

Der volle Inhalt der QuelleIn 1957, the State is the organiser of the public postal service in France through its central administration. That same year, a treaty was signed in Rome between six European States around the idea of a common market with a delegation of sovereignty. At first, the public postal service and the Europe of the Treaty of Rome develop separately. But in the early 1980s, the political, economic and technological context evolves and Europe decides to take an active interest in the matter of the postal service. After a phase of disinterest in postal matters, we enter in a phase of confrontation; Europe submits the postal service to the competition law: monopoly, the traditional organisation of the postal service, is challenged. Moreover, the French public postal service is transformed: La Poste, independent public operator is born. Following the period of confrontation, a period of dialogue follows, bringing together the Europe of the Treaty of Rome and the States members to write the postal law. Several guidelines are adopted, focused in particular on the universal postal service. By 2012, the process of liberalisation of the postal service is complete: there is no legal monopoly in Europe. This new openness is concomitant with the digital era. The postal service must now continue to adapt to this new ideological, technological and economical context: in its form – La Poste becomes a public limited company – as well as in its mission to serve the public interest, the raison d’être of the public service, so the public postal service is reconfigured

Der volle Inhalt der QuelleThe thesis undertaken aims to try to define a legal status of the procedure of taking out of bond of the postal sendings. The legal nature of the postal sendings justifies a customs treatment autonomous and distinct from the customs formalities applicable to the goods of the international commercial exchanges. The completed works should first of all help to answer the problems related to the legal difficulties of the definition of this procedure of specific taking out of bond and their consequences. The study will relate particularly to settlement of disputes between the customs authorities and the importers or exporters of international postal sendings in the event of litigation related to the taking out of bond. As a preliminary, it is thus necessary to raise and clarify the legal rules which are already applicable to the taking out of bond of the postal sendings, so much at the national and European level, that with the international level in this field. However, that appears difficult, and there is necessary to remain obstinate in front of the extreme diversity of the sources and the texts, strewn in many branches with the right. It is then necessarily necessary to try to redefine, clearly and simply, the concept of postal sending and the notion of universal postal service justifying the application of a specific procedure of taking out of bond of the postal sendings. The concept of universal postal service implies a fast taking out of bond of the postal sendings. The customs administrations have, they, the obligation to ensure the control of all the imported or exported goods their territories main roads. The main mission of the customs authorities is to protect the economic attractivity from the States. The customs agents must, on the one hand, take the customs duties and import taxes, on the other hand, to fight against the illicit traffics of goods prohibited or subjected to restriction. The delicate combination of the universalism of the postal service and the customs obligations must allow the recognition and the establishment of a procedure of taking out of bond specific to the postal sendings implying a new determination of the sendings concerned with the universal postal service and the installation of rules of taking out of bond obligatory and communes the whole of the international postal services. The implementation of an international cooperation reinforced between the postal services and the customs authorities is, in this direction, beforehand essential. The study must make it possible to make comprehensible, for the companies and the individuals national and European, the customs substantive law applicable to the postal taking out of bond. One will analyze in particular the customs infringements and rules sanctioning the various frauds which one finds most frequently in practice. The test on the definition of a legal status of the procedure of taking out of bond of the postal sendings will show that it is imperative to reinforce the powers and the means of control and sanctions of the customs authorities for this singular type of taking out of bond. The not-contentious and contentious appeals which are opened up for the debtors and applicants will also be the object of a particular treatment. The rights of the debtors or applicants are in particular ensured by the principle of control of the legality of the decisions of the Customs and Excise and of its agents by the legal judge. The legal judge and the European right limit and frame the exorbitant powers of the customs authorities
