Analýza a racionalizace zpětné logistiky u DHL Exel Supply Chain, Automotive UK / Analyses and rationalization of reverse logistics within DHL Exel Supply Chain, Automotive UK

Beneš, Martin January 2007 (has links)
This diploma thesis has been created based on the demand of the management of DHL Exel Supply Chain and Swindon Pressings Limited to increase the efficiency and utilization of resources employed within they operations. The theoretical introduction part is first of dealing with the terms "logistics" and "supply chain management" in the perspective of their use in the contemporary logistics theory, comparison of their meaning (are there differences) and explanation of their use in this thesis. Subsequently I am explaining "reverse logistic" and its position in the structures of corporations and logistics itself. Supply chain management and the concept of lean manufacturing combined with the six sigma approach are, from my point of view, essential for today's supplier-customer relationships. That is why those topics are examined in the last part of the theoretical chapter. Returnable packaging and the transport process are key elements of the second part -- practical part, the reengineering of logistics processes which occurred at Swindon Pressings Limited. The aim of this thesis is to analyze the give problem, develop problem solving options and critically comment them. Finally choose one of the options, implement it and document the process of "going live".

Adapting to Pandemics disruptions during the Covid-19: an analysis of DHL's Satregies for Maintaining Supply Chain Capabilities

DUFAY, Léa, VIROLLE, Apolline, GAY, Ulysse January 2023 (has links)
Background: COVID-19 pandemic had a vast and significant impact on today’s societies, in terms of economic, societal, and even environmental aspects. Global supply chains had to adapt to this changing landscape rapidly. Both supply and demand witnessed repercussions. The effects of COVID-19 on supply chains have been evident, with lockdowns and inconsistent supply and demand causing issues for international trade. Indeed, many companies were constrained to stop supply and production and could not deliver their goods.   Purpose: This study aims to investigate the impact of the COVID-19 pandemic on transportation operations in logistics companies, more precisely by using the case of DHL to emphasize our study. The purpose is to analyze the impacts that the crisis had on Logistics operations, by focusing on DHL and the way the company was impacted, understood and overcame the disruption. This study will take into consideration economic, social and environmental aspects.   Method: The research will be based on a case study and empirical evidence to provide a comprehensive understanding of the impact of the COVID-19 pandemic on DHL’s supply chain operations and more precisely on logistics and transport. We used the Triple Bottom Line approach to measure the economic, social, and environmental performances of DHL. Further, the analysis used in this paper is an inductive thematic analysis, to emphasize the findings and provide a better accuracy to our results.   Results: The study aims to identify the effects that COVID-19 had on logistics operations, and it more particularly seeks to highlight the strategies used by logistics companies that could be useful for other companies that need to build more resilient and flexible supply chains in the face of future disruptions. The findings of this thesis will be valuable to businesses, supply chain managers, and policymakers seeking to understand the role of improving their supply chains. Thanks to the interviews that were conducted, the findings highlighted several strategies that have been implemented by companies, such as the acceleration in automation, efforts put towards employee conditions, and restructuring companies.

RealTime and Anytime Supply Chain Planning

Schmalzried, Dirk January 2011 (has links)
Bisher sind die Planungsebenen des Supply Chain Management (SCM) konzeptionell, personell und softwaretechnologisch getrennt und oft hierarchisch organisiert. Geschäftsprozesse definieren die Übergänge von und Rückkopplung zwischen Ebenen grober, strategisch/ taktischer Planung und Ebenen feiner, operationaler Planung. Diese Trennung führt zu konzeptionellen, prozessualen und temporalen sowie zu systemtechnischen Defiziten im Supply Chain Planning (SCP). Kerngedanken des neuen Konzepts sind, alle heute üblichen Planungsebenen vollständig auf das operative Modell zu gründen die neuen Softwaresysteme vollständig im RAM zu verankern sowie mit neuen Nutzeroberflächen auszustatten, die den Aspekt der virtuellen Aggregation und Disaggregation der Daten zur Laufzeit befördern. Durch die Ergebnisse der Arbeit wird das den Stand der Technik darstellende Paradigma der sequenziellen, hierarchischen Planung verändert zu einem Konzept einer jederzeit ausführbaren (Anytime) Planung, welche Planungsergebnisse innerhalb sehr kurzer Antwortzeiten (Real-Time) liefert. Durch die schnellen Antworten können zudem ganz neue interaktive, simulationsbasierte Planungsprozesse anstelle bisheriger batchorientierter Prozesse eingeführt werden. Es werden Vorteile gegenüber dem alten Konzept und die praktische Machbarkeit anhand von Softwarefallstudien bewertet.

Supply chain management practices in construction and inter-organisational trust dynamics

Manu, Emmanuel January 2014 (has links)
The poor trust culture in the construction sector is often considered an inhibiting factor to collaboration success in the United Kingdom (UK) despite reform efforts. Numerous reform initiatives tend to have focused on improvements in client and main contractor aspects of construction supply chain relationships, prompting claims that failure to integrate subcontractors, suppliers and consultants into collaborative arrangements remains a major shortcoming. Main contractor and subcontractor relationships therefore continue to be typified by such problems as late payments, charging fees to tender for work, award of contracts based on cheapest price rather than best value, negative margins and demand of retrospective discounts and cash rebates; all of which negatively impact on trust. Some main contractor organisations however, continue to embed supply chain management practices as a strategy for levering value from subcontractors. Such collaborative practices and their implications for inter-organisational trust development, and indeed overall project outcomes, have nonetheless received limited attention in construction management research, raising significant questions on the empirical basis for their implementation. This research was thus undertaken to investigate strategic supply chain management practices adopted by UK main contractors and its implications for inter-organisational trust development during projects. The study adopts a multiple case study design so as to unravel complex subtleties of inter-organisational trust development in the main contractors’ supply chain during projects. With four purposefully selected UK main contractor organisations that had implemented strategic supply chain management, data was gathered through a supply chain workshop, semi-structured interviews, passive observations and documentary analysis. From analysis of the data, it was revealed that strategic supply chain management practices of the main contractors were instrumental for trust manifestation across cognition, system and relational based dimensions. These practices served as constitutive elements of face-to-face interactions through which inter-organisational trust developed, whilst providing the institutional framework to which respective supply chain parties directed their psychological expectations. These findings highlight the importance of maintaining a core of subcontractors from which the main contractor can leverage long-term value irrespective of economic climate. This can be achieved by adequately prioritizing relationally trusted subcontractors for sensitive and high risk work packages whilst ensuring that strategic supply chain management principles can be used to engender impersonal (cognition and system-based) trust dimensions amongst other subcontractors used on a project. Accordingly, a supply chain management oriented framework for engendering inter-organisational trust during projects has been developed based on the study findings and evaluated through semi-structured interviews with selected target participants. This framework does not only provide a systematic and coherent approach for implementing or benchmarking strategic supply chain management in a main contractor’s organisation, but can also be used to prioritize and promote different trust dimensions and their associated behavioural consequences on projects, depending on perceived work package risks.

The influence of market structure, collaboration and price competition on supply network disruptions in open and closed markets

Greening, Philip January 2013 (has links)
The relaxation of international boundaries has enabled the globalisation of markets making available an ever increasing number of specialised suppliers and markets. Inevitably this results in supply chains sharing suppliers and customers reflected in a network of relationships. Within this context firms buyers configure their supply relationships based on their perception of supply risk. Risk is managed by either increasing trust or commitment or by increasing the number of suppliers. Increasing trust and commitment facilitates collaboration and reduces the propensity for a supplier to exit the relationship. Conversely, increasing the number of suppliers reduces dependency and increases the ease of making alternative supply arrangements. The emergent network of relationships is dynamic and complex, and due in no small part to the influence of inventory management practices, tightly coupled. This critical organization of the network describes a system that contrary to existing supply chain conceptualisation exists far from equilibrium, requiring a different more appropriate theoretical lens through which to view them. This thesis adopts a Complex Adaptive Systems (CAS) perspective to position supply networks as tightly coupled complex systems which according to Normal Accident Theory (NAT) are vulnerable to disruptions as a consequence of normal operations. The consequential boundless and emergent nature of supply networks makes them difficult to research using traditional empirical methods, instead this research builds a generalised supply network agent based computer model, allowing network constituents (agents) to take autonomous parallel action reflecting the true emergent nature of supply networks. This thesis uses the results from a series of carefully designed computer experiments to elucidate how supply networks respond to a variety of market structures and permitted agent behaviours. Market structures define the vertical (between tier) and horizontal (within tier) levels of price differentiation. Within each structure agents are permitted to autonomously modify their prices (constrained by market structure) and collaborate by sharing demand information. By examining how supply networks respond to different permitted agent behaviours in a range of market structures this thesis makes 4 contributions. Firstly, it extends NAT by incorporating the adaptive nature of supply network constituents. Secondly it extends supply chain management by specifying supply networks as dynamic not static phenomena. Thirdly it extends supply chain risk management through developing an understanding of the impact different permitted behaviour combinations on the networks vulnerability to disruptions in the context of normal operations. Finally by developing the understanding how normal operations impact a supply networks vulnerability to disruptions it informs the practice of supply chain risk management.

Investigating socially responsible purchasing perceptions : perspective from the food and drink supply chains in Nigeria

Ogunyemi, Titilayo C. January 2017 (has links)
The purpose of this research was to examine how social issues are perceived and addressed in the food and drink sector, focusing on the narrower context of Nigerian purchasing practices, identifying the drivers, and barriers to the adoption of socially responsible purchasing (SRP) in the organisational supply chains. This research is underpinned by the stakeholder and institutional theories with the use of Carroll's CSR pyramid to explain the perceptions of stakeholders and the level at which each of the practices is in the pyramid. An in-depth study was conducted in multinational and indigenous food and drink organisations in Nigeria. Data was gathered from practitioners comprising of employees, managers, and executives by means of questionnaires and semi-structured face-to-face interviews to triangulate data sources. Drawing on the data collected, respondents' perspective of the meaning of socially responsible purchasing provided new insights into the phenomenon with various meanings and contestations. The findings suggest that socially responsible purchasing practices have a moderate positive influence on the organisations' supply chains within an unstable economic environment. Some of the practices were perceived to be voluntary and having an ethical underpinning while others were related to legal responsibilities. The findings suggest that the moderate influence is due to internal and external factors within the institutional environment. This research context was restricted to private organisations in the food and drink sector in Nigeria which might limit the generalisation of the findings. However, the findings may be transferable to other sectors of the economy where socially responsible purchasing issues are addressed in the supply chains. In practice, SRP is perceived to be an important element of CSR and supply chains despite the barriers to its implementation. The practices should be properly implemented to help in the sustenance of organisational supply chains. This research will be insightful for other industrial sectors as well as developing economies in Africa. The findings advance the stakeholder and institutional theories by providing an in-depth perception of various stakeholders and SRP practices within the institutional environment of organisations' supply chains. The research has contributed to enriching the literature on CSR and supply chains sustainability in Nigeria which has a relative shortage of literature on CSR and supply chain.

Capacity Planning And Range Setting In Quantity Flexibility Contracts As A Manufacturer

Pesen, Safak 01 January 2003 (has links) (PDF)
Quantity Flexibility contract is an arrangement where parties agree upon a scheme of forming ranges on volumes for their future transactions. The contract is based on setting upper and lower limits on replenishment orders as simple multiples of point estimates updated, published and committed by the buyers. We introduce a manufacturer with a limited capacity / also capable of subcontracting, for deliveries with a known lead time. He offers a Quantity Flexibility (QF) contract to a buyer while he has an active contract with another buyer serving a market with known demand forecast distributions. Using two-stage stochastic programming we study the effects of flexibility multiples and the environmental factors on the buyers&amp / #8217 / incentives and manufacturer&amp / #8217 / s capacity planning. Finally, the motivations of the Supply Chain actors to behave independently or to be involved into the integrated iv supply chain where information asymmetry is removed are investigated. Our experiments underline the critical roles played by the forecast accuracy and information sharing.
