Bid Forecasting in Public Procurement / Budgivningsmodeller i offentliga upphandlingar

Stiti, Karim, Yape, Shih Jung January 2019 (has links)
Public procurement amounts to a significant part of Sweden's GDP. Nevertheless, it is an overlooked sector characterized by low digitization and inefficient competition where bids are not submitted based on proper mathematical tools. This Thesis seeks to create a structured approach to bidding in cleaning services by determining factors affecting the participation and pricing decision of potential buyers. Furthermore, we assess price prediction by comparing multiple linear regression models (MLR) to support vector regression (SVR). In line with previous research in the construction sector, we find significance for several factors such as project duration, location and type of contract on the participation decision in the cleaning sector. One notable deviant is that we do not find contract size to have an impact on the pricing decision. Surprisingly, the performance of MLR are comparable to more advanced SVR models. Stochastic dominance tests on price performance concludes that experienced bidders perform better than their inexperienced counterparts and companies place more competitive bids in lowest price tenders compared to economically most advantageous tenders (EMAT) indicating that EMAT tenders are regarded as unstructured. However, no significance is found for larger actors performing better in bidding than smaller companies. / Offentliga upphandlingar utgör en signifikant del av Sveriges BNP. Trots detta är det en förbisedd sektor som karakteriseras av låg digitalisering och ineffektiv konkurrens där bud läggs baserat på intuition snarare än matematiska modeller. Denna avhandling ämnar skapa ett strukturerat tillvägagångssätt för budgivning inom städsektorn genom att bestämma faktorer som påverkar deltagande och prissättning. Vidare undersöker vi prisprediktionsmodeller genom att jämföra multipel linjära regressionsmodeller med en maskininlärningsmetod benämnd support vector regression. I enlighet med tidigare forskning i byggindustrin finner vi att flera faktorer som typ av kontrakt, projekttid och kontraktsplats har en statistisk signifikant påverkan på deltagande i kontrakt i städindustrin. En anmärkningsvärd skillnad är att kontraktsvärdet inte påverkar prissättning som tidigare forskning visat i andra områden. För prisprediktionen är det överraskande att den enklare linjära regressionsmodellen presterar jämlikt till den mer avancerade maskininlärningsmodellen. Stokastisk dominanstest visar att erfarna företag har en bättre precision i sin budgivning än mindre erfarna företag. Därtill lägger företag överlag mer konkurrenskraftiga bud i kontrakt där kvalitetsaspekter tas i beaktning utöver priset. Vilket kan indikera att budgivare upplever dessa kontrakt som mindre strukturerade. Däremot finner vi ingen signifikant skillnad mellan större och mindre företag i denna bemärkning.

Compras públicas sustentáveis: aplicação da Agenda Ambiental da Administração Pública nos pregões municipais

REZENDE NETO, Renato 20 June 2017 (has links)
Por meio deste estudo, avaliou-se o impacto da adoção da Agenda Ambiental da Administração Pública (A3P) nos editais de licitação, na modalidade “pregão”, em dois municípios localizados na região Sul e Sudoeste de Minas Gerais, Varginha e Três Corações. O propósito foi identificar as diferenças, se é que existem, na descrição dos produtos licitados pelos dois municípios, ressaltando que, diferente de Varginha, Três Corações integra a Agenda Ambiental (A3P) desde o ano de 2013. Registre-se que a mencionada Agenda Ambiental é um programa que visa a implementar a gestão socioambiental sustentável nas atividades administrativas e operacionais do Governo. Assim, buscou-se verificar se as características dos produtos licitados se modificam conforme o município participe ou não da Agenda Ambiental da Administração Pública (A3P). A partir da análise dos editais de licitação na modalidade pregão do ano de 2015, de ambos os municípios envolvidos, identificou-se que a descrição dos produtos licitados não englobou, salvo pequenas exceções, critérios relativos à sustentabilidade. De posse dessa informação, entendeu-se cabível a elaboração de um plano de melhorias dos processos licitatórios, de modo a conciliar o sistema de licitações municipais ao eixo temático das compras públicas sustentáveis, um dos seis eixos estruturais da Agenda Ambiental da Administração Pública. / This study evaluated the impact of the adoption of the Public Administration Environmental Agenda (A3P) in the bidding documents, in the "pregão" modality, in two municipalities located in the South of Minas Gerais, Três Corações and Varginha. The purpose was to identify the differences, if any, in the description of the products tendered by the two municipalities, noting that, unlike Varginha, Três Corações is part of the Environmental Agenda (A3P) since 2013. It should be noted that the mentioned Environmental Agenda is a program that aims to implement sustainable socio-environmental management in the administrative and operational activities of the Government. Thus, it was sought to verify whether the characteristics of the products tendered change depending on whether the municipality participates or not in the A3P Environmental Agenda. Based on the analysis of the bidding documents in the negotiation modality of the year 2015, of both municipalities involved, it was identified that the description of the products tendered did not include, with minor exceptions, criteria related to sustainability. With this information, it was considered feasible to draw up a plan to improve the bidding processes, in order to reconcile the municipal bidding system with the thematic axis of sustainable public procurement, one of the six structural axes of the Public Administration Environmental Agenda.

Begreppet onormalt lågt anbud i direktiv 2004/18/EG om offentlig upphandling : Om begreppets innebörd och konsekvenserna av att det saknas förbud mot att anta onormalt låga anbud / The concept of abnormally low tender and the directive 2004/18/EC on public procurement : About the significance of the concept of abnormally low tender, and consequences of the lack of prohibitive legislation

Liljeblad, Elin January 2005 (has links)
<p>Som en följd av Sveriges medlemskap i EU har offentliga upphandlingar kommit att få allt större betydelse eftersom de nu kan ske inom ett betydligt större geografiskt område än tidigare. En konsekvens av detta är att konkurrensen blivit allt hårdare och nya regler införs i takt med den snabba utvecklingen. Ett av resultaten av den hårda konkurrensen på upphandlingsmarknaden har visat sig vara att en del leverantörer lämnar anbud med onormalt låga priser för att vinna upphandlingskontraktet. Förekomsten av onormalt låga anbud i offentliga upphandlingar medför allvarliga negativa konsekvenser såsom att konkurrensen snedvrids, effektiviteten minskar och kostnaderna ökar. Detta påverkar både den upphandlande enheten, leverantören som bjudit onormalt lågt, de leverantörer som slagits ut samt konsumenterna. Att det saknas ett förbud i upphandlingslagstiftningen mot att anta onormalt låga anbud är därför allvarligt. Syftet med denna framställning är att undersöka innebörden av begreppet onormalt lågt anbud i offentliga upphandlingar, belysa problemet med och konsekvenserna av att lagstiftning och regelverk inte i tillräcklig utsträckning uppmärksammar de risker som kan vara förenade med antagandet av onormalt låga anbud samt försöka finna en lösning på problemet.</p> / <p>As a result of Sweden’s membership of the European Union, public procurement has gained more importance, mainly due to the larger geographic territory available.

The presence of these abnormally low tenders in public procurement may have serious negative consequences such as distortion of competition and reduced efficiency, potentially causing delays and waste of resources in the procurement process. This will affect both the contracting authority, the tenderer that has won on an abnormally low bid, the other unsuccessful tenderers, and the ultimately consumers. The fact that public procurement law does not prohibit authorities from accepting abnormally low tenders is therefore potentially very serious. The main objective of this dissertation is to examine the significance of the concept of abnormally low tender, to illuminate the issues surrounding and consequences of the legislative lack of attention to the risks associated with accepting abnormally low tenders, and finally to propose solutions to these issues.</p>

Italian entrepreneurs of the construction business in a time of economic recession : ideas, strategies and movements

Sischarenco, Elena January 2017 (has links)
This thesis is based on an ethnographic study of entrepreneurs of the construction business in Lombardy, Northern Italy. The aim is to gain some understanding of this business, of entrepreneurialism, and of individuals in a non-stereotypical light through a full and complex account of their daily lives. The aim is to reveal the thoughts, actions and strategies of particular local actors in their everyday contingency and contradictoriness. No attempt is made to simplify the complexity of their understandings and practices for the sake of producing a single encompassing and consistent image. Many similarities were found between the practices of entrepreneurialism and those of the discipline of anthropology. Knowledge and information are constantly sought after but are recognised as emerging in unexpected places and times and as being socially negotiated. Apprenticeship is often used as a methodology, and learning often happens through experience. Contextual application of knowledge is seen as essential. In order to exchange information and knowledge, to collaborate with other businessmen or to simply get a job, trust is fundamental and constantly negotiated. Personal relationships and trust become particularly important in an uncertain market situation, as ways to face risk. Trust is acquired slowly and accorded contextually, through face-to-face interaction and cultivated relationships, but also through positive recommendations or simply a feeling of sympathy. Knowledge, apprenticeship, trust and risk are key themes of the thesis. The blurred borders between the distinct individual personalities of my informants and their collective identities and commonalities are also discussed. The personality of an entrepreneur is seen as ideally complex, in which many (possibly contradictory) characteristics can be expected to be present, but also ideally balanced, each manifesting itself in specific situations. The ethnography also explores the fragility of the entrepreneur, in apparent contradiction to their strong and charismatic personalities. It is seen to be despite and because of their positions of power that they also feel vulnerable: their discourse is imbued with their fears for their businesses in a difficult period of economic crisis. Finally, through a ubiquitous desire to control markets and the future, we also encounter forms of corruption; corruption that is often condemned verbally but nevertheless is present in the business world and amplified by public and media discourses. The mechanisms by which work that is put out to tender is subject to possible manipulation are examined, and the ideas of the entrepreneurs about these practices are described—again demonstrating how thoughts and practices are often self-contradictory in their contextual relevance and application.

Le régime juridique de l’accès aux réserves d’hydrocarbures, enjeux de la coopération entre Etats producteurs et investisseurs étrangers / Accessing hydrocarbon reserves, the legal and regulatory framework concerning cooperation between States and foreign investors

Lebdioui, Amina 15 December 2017 (has links)
Lorsque l’Etat décide de l’exploration ou de l’exploitation de ses réserves d’hydrocarbures, il n’est soumis à aucune règle internationale quant aux modalités de mise en œuvre de cette décision. Cette absence d’obligations n’a pas empêché les Etats développer, au niveau national, des règles réduisant leur liberté quant à la sélection des opérateurs. Aux négociations secrètes qui ont longtemps prévalu dans le secteur pétrolier, se sont alors substituées des procédures de mise en concurrence ouvertes s’appuyant sur des critères objectifs. Ayant pour but d’attirer l’investissement étranger et de faciliter la conclusion des contrats, elles se sont progressivement généralisées et standardisées, tant dans leur formalisme que dans leurs conditions. On constate alors un processus d’uniformisation globale des conditions d’accès aux réserves, auquel les institutions financières internationales ont directement ou indirectement pris part. L’un des aspects cruciaux des procédures d’attribution des droits a trait au rôle de l’entreprise pétrolière nationale. Celle-ci dispose souvent d’un traitement préférentiel. Dans de nombreux Etats, elle a en outre été traditionnellement chargée de l’octroi des contrats, combinant ainsi des fonctions qui lui ont permis de devenir un acteur incontournable du secteur. La standardisation de ses attributions a également fait l’objet d’un processus de convergence internationale, qui modifie le rapport entre l’Etat et l’investisseur étranger. / When the State decides to undertake the exploration or exploitation of its hydrocarbons reserves, it is not subject to any international obligation concerning the implementations of such decision. This lack of obligations has not prevented states from developing rules at the national level to reduce their freedom in the selection of operators. The secret negotiations that have long prevailed in the petroleum sector have been replaced by more transparent and open competition procedures, backed by objective criteria. With the objective of attracting foreign investment and facilitating the process of conclusion of contracts, those procedures have been progressively generalized and standardized, both in their formalism and in their terms. We consequently observe a global standardization process of the terms of access to reserves, in which international financial institutions have been directly or indirectly involved.One of the essential aspects of the procedure of rights allocation relates to the role of the national oil company. It enjoys preferential treatment, which has implications on the modalities of participation of foreign firms. Furthermore, in several states, the national oil company has been responsible for granting petroleum contracts, thereby combining functions that render it a key actor in the sector. The standardization of its attributions has also undergone a process of international convergence, which alters the relation between the State and the foreign investor.

Les appels d’offres municipaux, au lendemain de la Commission Charbonneau

Perreault, Julie 04 1900 (has links)
Le présent mémoire est divisé en deux parties. La première, un peu plus théorique, se veut un bref constat des problèmes reliés à l’octroi des contrats municipaux au fil du temps ainsi qu’un rappel des règles actuelles en matière d’attribution des contrats. La seconde partie porte sur les bonnes pratiques à adopter lors d’un appel d’offres, les zones grises et les erreurs à éviter lors du processus menant à l’adjudication d’un contrat. Dans un premier temps, l’auteure traite de la rédaction de l’appel d’offres, de sa publication, de l’ouverture des soumissions et des formalités à suivre afin de déterminer la soumission devant être retenue. Par la suite, elle aborde les concepts de division de contrat et d’avis d’intention. Finalement, le dernier chapitre relate les différents mécanismes de plaintes dans le milieu municipal. À la fin du mémoire, six (6) annexes viennent illustrer, sous forme de tableaux ou de schémas, différents concepts et étapes clés en matière de gestion contractuelle. / This master’s thesis is divided into two parts. The first one is a bit more theoretical and is intended to be a brief overview of the problems linked to the awarding of municipal contracts over time, as well as a reminder of the current rules governing the awarding of contracts. The second part informs on the best practices to be followed during a call for tenders, the gray areas, and the errors to avoid during the process leading to the awarding of a contract. First, the author addresses the writing of the call for tenders, its publication, the opening of tenders, and the formalities to be followed in order to determine the tender to be selected. Next, she discusses the concepts of contract division and notice of intention. The last chapter describes the various complaint mechanisms in the municipal sector. At the end of the thesis, six (6) appendices illustrate, using tables or diagrams, various key concepts and stages in terms of contractual management.

Le juge administratif et les libertés économiques : contribution à la définition des libertés économiques au sein de la jurisprudence adminuistrative / Administrative judges and economic freedoms : contributing to the definition of economic freedoms in administrative case law

Marson, Grégory 25 January 2012 (has links)
L'étude a pour principal objet l'identification et la définition des libertés publiques économiques au sein de la jurisprudence administrative. Au terme de cette recherche, il apparaît que la liberté d'entreprendre constitue la seule véritable liberté publique économique utilisée par le juge administratif. Elle est en effet la seule qui a pour fondement la protection de droits ou d'intérêts subjectifs liés à la personnalité juridique, en particulier celles des personnes privées. Elle recouvre deux prérogatives essentielles : l’accès à une activité économique et l’exercice d’une activité économique. Si l'expression « liberté d'entreprendre » n'est pas apparue au sein de la jurisprudence administrative mais au sein des jurisprudences constitutionnelle et européenne, il importe de ne pas se laisser abuser par les mots employés. Celle-ci est en réalité présente au sein de la jurisprudence administrative depuis fort longtemps sous l'expression « liberté du commerce et de l'industrie ». A ce titre, elle recouvre un certain nombre d'autres appellations qui varient en fonction du contexte. Même si le juge administratif considère - à l'image du juge constitutionnel ou du juge européen - qu'il s'agit d'une liberté de second rang, il n'en demeure pas moins qu'il s'agit d'une liberté de valeur constitutionnelle. La définition et la classification de la « libre concurrence » s'avèrent plus problématiques. Celle-ci recouvre deux aspects distincts :- un aspect dans lequel elle doit être envisagée comme le respect du principe d'égale concurrence, c'est-à-dire comme celui d'une déclinaison, le cas échéant rénovée, du principe d'égalité. Dans cette optique, elle peut revêtir un aspect subjectif, c’est-à-dire qu’elle protège un droit dont le fondement se trouve dans la personnalité juridique, alors même que son objet principal reste la protection du mécanisme de marché.- un aspect dans lequel elle doit être regardée comme un ordre concurrentiel. Dans cette optique, elle ne peut être assimilée à une liberté publique mais doit être envisagée comme un objectif ou un impératif d'intérêt général correspondant au bon fonctionnement concurrentiel du marché. Les prérogatives ou intérêts que les opérateurs économiques tirent de la défense de cet ordre concurrentiel ne leur sont pas accordés en raison de leur seule personnalité. Ces prérogatives et intérêts sont défendus de manière subsidiaire puisque c’est l’atteinte au fonctionnement concurrentiel du marché qui est en premier lieu et avant tout prohibée. Les prérogatives et intérêts que les opérateurs tirent de la défense de l’ordre concurrentiel trouvent leur source et leur assise dans la liberté d’entreprendre. C’est cette liberté qui octroie aux personnes morales et physiques le droit d’accéder à l’activité économique et le droit de l’exercer. La libre concurrence a pour effet de garantir et de renforcer l’effectivité de ces deux prérogatives fondamentales. / The primary purpose of this study is to identify and define economic public freedoms in administrative case law. The research shows that free enterprise is the only genuine public economic freedom relied upon by administrative judges. It is indeed the only one based on protecting the subjective rights or interests that are related to the legal personality, especially when it comes to individuals. It covers two essential rights: access to an economic activity and the running thereof. If the expression "free enterprise" was not created by the administrative judges but by the constitutional and European judges, it has however been known for a long time by administrative judges as "freedom of trade and industry." As such, it has a number of different names, which may vary depending on the context. Even if administrative judges consider – like their constitutional and European counterparts – that is it a secondary freedom, it is still a constitutional freedom.The definition and classification of "free competition" are more problematic, since such freedom covers two different aspects:- it may first be considered the respect of equal competition, as a new version of the equality principle. In this context, it can take a subjective aspect since it protects a right based on legal personality, even though its primary purpose is to protect market mechanisms.- it may also be considered as a competition system. From this perspective, it cannot be considered a public freedom but rather a goal or a requirement of general interest in the market good competitive functioning. The rights or interests of economic actors that derive from the protection of the competition system are not granted on the basis of their legal personality alone. The protection of those rights and interests in only subsidiary; interfering with free competition on the market is first and foremost prohibited. The rights and interests of economic actors in protecting the competition system have their source and guarantee in free enterprise. This freedom gives legal and natural persons the right to access and to run a business. Free competition ensures and reinforces the effectiveness of these two fundamental rights.
