Communication and interactivity in B2B relationships

Unknown Date (has links)
This research explores the impact of interactive communication on business-to business (B2B) relationships. In the past decade the internet and especially social media as a mode of communication has grown rapidly in both consumer and business markets. Drawing on marketing channels and communications literature this paper identifies the dimensions of interactive communication and develops a theoretical framework to examine their impact on satisfaction, commitment, and advocacy. Media synchronicity theory and the concept of the internet as an alternative to the real world are used to distinguish between digital and non-digital modes of communication. Relationship marketing is used to identify the dimensions of interactivity: rationality, social interaction, contact density, and reciprocal feedback. The framework developed is usedto explore the influence of face-to-face (F2F), digital, and traditional, impersonalcommunications on the dimensions of interactivity.Hypotheses linking the mode of communication: personal, digital, and impersonal with the dimensions of interactivity and relational outcomes are empirically examined with data from the commercial printing and graphic design industry. Confirmatory Factor Analysis is used to analyze the measurement and structural model. Personal, F2F communication has the greatest impact on social interaction, reciprocal feedback, and number of contacts. Digital communication has a weaker effect on these dimensions and impersonal communication has the weakest effect. Personal and Digital have equal impacts on rationality and rationality is the only dimension of interactivity positively associated with relationship satisfaction. Contact density has a negative impact on relationship satisfaction and this negative impact is greater with personal communication that it is with digital. The study shows that affective commitment leads to advocacy in a B2B channel, but trust and calculative commitment have no impact on advocacy. The findings of the study have implications for both managers and researchers regarding the mode and content of communications in B2B relationships. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2013.

Delivery planning under uncertainty in logistics and express industry. / CUHK electronic theses & dissertations collection

January 2007 (has links)
In this dissertation, we aim to investigate some delivery planning problems under different aspects of uncertain conditions in order to present some insights on how to develop more efficient and effective logistics solutions in the challenging, dynamic and competitive industry of express delivery nowadays. / Lastly, we introduce a travel time estimation method which can be considered as an upstream extension on the first delivery planning problem or any routing problems that require travel time in a road network as an input parameter. We realize that different trips may traverse on some links that are transited by other trips as well; and therefore linear and quadratic programming models can be developed to infer the travel time of any road segments which are traversed by more than one trip from the consideration of the common road segments of various trips. Bus routes information is proposed as the data source because of their coverage on the road network and their data available. Robustness of the proposed models is evaluated according to the deviation between the resultant inferences and the means of the segment travel times. It is found that the basic models suffer from a fundamental problem of underspecification issue if the number of observed trips (i.e. constraints) is fewer than the number of road segments (i.e. variables) to be estimated. Therefore, two additional types of constraints are introduced to address these issues. / The focus of the second delivery planning problem addressed in this dissertation is switched to the randomness of the demands at the delivery locations. We consider a single-depot problem in which a large volume of packages have to be delivered in a dense and small area with a lot of high-rise buildings within an extremely tight delivery commitment time window. At each vertex, the package volume (i.e. demand) is a highly stochastic variable and its service time is also dependent on the demand. This version of problem is typically faced by express service providers which offer premium express services to customers that are protected by the money back guarantee (MBG) condition. We name this version of problem as a time-constrained vehicle routing problem with stochastic demands and service times (SVRP-D). Since both the demand and service time of a vertex are stochastic, the vehicle capacity and the commitment-time (i.e. deadline) constraints may not be satisfied after the demands are realized, and recourse action is thus necessary to "rescue" the "infeasible" delivery plan through additional effort and cost. Three typical recourse actions are independently considered: (1) restocking; (2) outsourcing; and (3) reassignment. A two-stage stochastic integer programming is proposed such that the first-stage problem is to determine a set of a priori routes which minimize the vehicle travel cost and the cost for any known recourse actions. Dependent on a first-stage solution, the second-stage problem is to decide the optimal recourse plan with least cost according to the pre-determined recourse action. / Two delivery planning problems and one travel time estimation model under various aspects of randomness are addressed in this dissertation. The first delivery planning problem considers an extension on a well-known problem---the vehicle routing problem with time windows (VRPTW), where the travel time required between each delivery location is a stochastic variable, instead of a fixed value. We name this version of the VRPTW as a vehicle routing problem with time windows and stochastic travel times (VRPTWST). A two-stage stochastic integer programming with recourse model is developed and its objective is to minimize the vehicle travel cost together with the expected loss due to the violation of the delivery time windows. An exact branch-and-cut (B&C) algorithm is proposed. This algorithm is effective for small-size problems, e.g. instances with only 8 vertices. For larger-size problems, some modifications on the B&C algorithm are suggested to improve the solution time with only a small deviation from optimality. / Wong Chi Fat. / "May 2007." / Adviser: Janny Leung. / Source: Dissertation Abstracts International, Volume: 69-01, Section: B, page: 0596. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2007. / Includes bibliographical references (p. 256-270). / Electronic reproduction.

Information revision and decision making in a two-stage supply chain. / CUHK electronic theses & dissertations collection / Digital dissertation consortium / ProQuest dissertations and theses

January 2001 (has links)
As information revision is becoming a more and more common practice in industry, we put our emphasis on the context of information revision and decision making in a supply chain. This dissertation is concerned with the analysis of information updating, competitive study of a two-level supply chain, and volume flexible contract together with spot market purchase. / For the competitive study, we focus on the dynamics of competitive behaviors between the supplier and the buyer. For the demand and demand forecast with single-peak probability distribution functions, we prove the existence of a unique Stackelberg equilibrium from the Stackelberg game at each stage. / For the contract study, we develop a model which takes both volume flexible contract and spot market purchase into consideration. The optimal order quantity at each stage is determined. Furthermore, by making use of the stochastic comparison theory, we investigate the impact on profit and the optimal order quantity induced by the accuracy of the demand forecast. (Abstract shortened by UMI.) / With the framework of information revision, the decision dynamics is the focus of supply chain management. We primarily concentrate on the competitive and cooperative study of a simple two-level supply chain. / With the phenomenon observed from local industry, our research, on the analysis of information updating within a node in a supply chain, involves three tasks: (a) analyzing the data collected from local industry; (b) modeling demand forecasting process based on the observation; and (c) determining the operational factors which drive the fluctuation of demand forecast variances. With regard to (a), we observe that, as the forecasting horizon decreases, the variances of forecasts increase and variances of forecasting errors decrease. With regard to (b), we make use of Bayesian analysis approach to model the demand forecasting process, and prove that, under multi-stage demand forecasting structure, both the variance and the precision of demand forecast increase. Concerning (c), four operational factors, i.e. price promotion, lotsizing, new product introduction, and pre-confirmed order, are considered to be the causes. / Hua Xiang. / "November 2001." / Adviser: Houmin Yan. / Source: Dissertation Abstracts International, Volume: 63-01, Section: B, page: 0506. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2001. / Includes bibliographical references (p. 104-111). / Electronic reproduction.

Competition and collaboration issues in technology development and deployment

Erzurumlu, Sadik Sinan 28 August 2008 (has links)
In today's marketplace firms have to become specialized in specific technological aspects in product development due to intensifying competition. Further, the increasing complexity of offerings make firms become more dependent on other value-chain contributors such as providers of complementary and component technologies. Therefore, in addition to the inherent market of appeal of product, a successful introduction may depend on the firm's interactions with suppliers and even "competitors". These interactions with other firms in the marketplace present a unique set of challenges to firms. In this dissertation, we explore how a firm's approach to interacting with supply chain partners and/or competitors may depend upon how its product provides value to customers. In the first essay, we look into how a firm should design the interdependence between a durable good and a consumable such as a printer and a cartridge and utilize the benefits of an industry of generic consumable suppliers. In the second essay, we analyze the different approaches that firms adopt while commercializing their technologies to competitors in a networked environment (such as telecommunications). We identify the impact of the competitor's development capabilities on the trade-off between the increased competition and network benefits. In the third essay, we explore situations in which firms collaborate to develop a component innovation that they later market individually; they codevelop and jointly market; and they choose to individually develop and market. We consider how competitive strategies between development partners should consider the influence of supplier formation on the investment incentives of an OEM. In summary, this dissertation examines how the management of interactions with supply chain partners and competitors can play an important role in technology development and deployment. Our results highlight key trade-offs and provide insights for managers who are involved in developing and deploying new products. / text

The role of GMSA to assist their suppliers with the successful implementation of lean practices

Conybeare, Nabiel January 2007 (has links)
Over the past couple of decades traditional manufacturing techniques have been replaced by lean production around the world. This change in production methodology brought about the opportunity for numerous companies to reduce costs and customer lead time through the application of this lean philosophy. The worldwide shift from traditional manufacturing to lean manufacturing can be ascribed to the success of Toyota Motor Company. Lean manufacturing refers to a manufacturing improvement process in order to minimize or eliminate waste while maximizing production flow (Tapping, et al., 2002:30). A value stream includes all the operations and processes to transform raw material into finished products or services. Value stream is a management tool used for the planning of a production process involving lean techniques through systematic data capturing and analysis (Tapping 2002 et al., 41). Value stream is a proven process for planning the improvements that will allow companies to develop lean practices. One key to Toyota’s success that GMSA and many other South African companies have not been able to emulate is the transformation of their suppliers to apply the lean philosophy. This lack of supplier transformation is due to various reasons including supplier proximity, supplier relationships, supplier performance levels, and the ordering policies used for supplied parts. Even though many manufacturing organizations realize the importance of practicing lean manufacturing techniques, few organizations apply lean techniques with the required knowledge and tools to transform their organization from traditional manufacturing to lean manufacturing. This research project is based purely on the lean manufacturing principles and philosophies. The aim of the study is to make GMSA’s suppliers aware of the principles and processes of lean manufacturing and to develop a lean implementation strategy to assist organizations with the successful implementation of lean practices. In order to correctly implement and sustain lean manufacturing practices this study will also focus on supplier support and development and the behavior an organization must exhibit to make this transformation a success. The research methodology comprised the following steps: • A literature study was performed by the researcher to get a better understanding of the principles and philosophies of lean manufacturing; • A second literature study was also performed to get a better understanding of the continuous improvement philosophies of lean manufacturing including supplier support & development; and • To accomplish the objectives of this study, interview sessions were conducted with four senior managers of General Motors South Africa. The researcher selected the interviewees from the following departments within General Motors South Africa: Global Purchasing and Supply Chain; Supplier Quality and Development; Vehicle Assembly Operations and Material Supply. The interviewees from General Motors South Africa were identified as qualified data sources for this research project, as their professional opinions and viewpoints could best address the research questions.

Investigating sustainable supply chain practices within the luxury brand market

Colesky, Yolanda January 2017 (has links)
Luxury fashion brands seem to contradict sustainability. The values of sustainability are commonly associated with terms such as sharing, collaboration, austerity, and collective thinking. Luxury, however, is associated with excess, self-indulgence, delight and decadence (Kapferer & Bastien, 2012:360). Further paradoxes exist where the apparel of the luxury consumer is often manufactured by labourers in low wage-paying producing countries. High wastage is evident in the seasonality of the fashion industry. However, work opportunities are created by the fickleness of the fashion industry and the constant need to own the most current designs (Black, 2012:8). Owing to the high visibility of luxury fashion and the contractions between one -- on the one hand -- supplying income to families by way of employment and -- on the other hand -- not complying to sustainable international human resource practices, fashion brands are the focus of many non-governmental organisations (NGOs) that use the mass media to expose any social wrongdoing in the industry. Luxury fashion brands are constantly in the spotlight, as highlighted in articles posted by the Clean Clothes campaign, a custodian for employees in the global garment industries; Greenpeace; and People for the Ethical Treatment of Animals (PETA). An example of such practices was when Greenpeace reported in 2009 that shoe brands such as Timberland and Clarks were manufactured from leather sourced from the hides of cattle in illegally deforested areas in Brazil. This provided negative publicity for these luxury shoe brands as well as for the Brazilian government that was financing this project (Vurro, Russo & Perrini, 2009:609). The luxury fashion brand industry, as well as the consumers of luxury fashion labels, are accused -- often only for the sake of sensationalism -- of living in the lap of luxury whilst maintaining a supply chain that is riddled with unsustainable practices. The social structure and hierarchy of patrons within a community have, since the Middle Ages, been signalled by the clothes they wore. Social class was a birthright. Today, sporting luxury brands continues to serve as status symbols, but unlike mediaeval times, it is not limited to people with a high social standing at birth as one can work for status, and purchase the items because one deserves them. (Han, Nunes, & Drèze, 2010:15). In 2009, during the International Herald Tribune (IHT) Suzy Menkes, the fashion editor at The Herald, called for “luxury”’ and “fashion” to be separated. Luxury prides itself in its handcrafted garments manufactured by respected tradesmen in the industry. The outcome is that the manufactured goods are made to last a lifetime (Gibson, 2012:23).

The port of Maputo as an alternative supply chain gateway in Southern Africa

Greeff, Jacques, Venter, Carli 27 August 2015 (has links)
M.Phil. / Successfully establishing an organisational service delivery footprint in Africa is a challenge that faces many South-Africa-based companies. Africa is a large continent, containing numerous countries, dialects and cultures. Each country presents its own set of unique opportunities and threats, and therefore a focused approach is required to develop a plan for organisations to not only grow into new markets and to service new clients, but also to expand service-rendering capability among its current clients by providing services from the product source to their end destination in Africa. It is therefore the purpose of this research project to focus on Mozambique and the Port of Maputo, with a detailed consideration of the strategic value that the Port of Maputo presents to organisations on the basis of its geographic location and proximity to product sources, both within Mozambique and its neighbouring countries ...

Erasmus, Bradley Quentin January 2006 (has links)
The underlying objective of the research is to assess the nature of the supplier training at Volkswagen of South Africa (VWSA). To achieve this objective, a theoretical study was conducted to establish what literature reveals to be the most important theory of supply chain management as well as supplier development geared towards lean manufacturing. The information obtained in the literature study was analysed to solve the main problem namely, an assessment of the nature of the supplier training at Volkswagen of South Africa (VWSA). The research was divided into two questionnaires: The first questionnaire is targeted at the suppliers. This questionnaire has two sections namely section A, the biographical data and section B attempts to determine the quality systems and manufacturing requirements. It further attempts to gauge training support and needs as compared to other OEM’s. The second questionnaire is targeted at the Supplier Development Manager. The aim of this questionnaire is to establish what the current training offerings are, the source of what VWSA teachers and the awareness of the Toyota Training College.

Improving supply chain competitiveness through the application of technology : a case study on a routing and scheduling system

Hollander, Ryan 25 October 2010 (has links)
M.Comm. / In the last hundred years there has been a technological revolution that has forced people to change the way they live and run their organisations. This technological revolution has had a major impact on the business world. Coyle, Bardi and Langley (2003; 57) have suggested that “the rate of change has accelerated with consequent negative impacts if organisations do not change.” With today’s emphasis on cutting costs, streamlining expenses while at the same time trying to offer a competitive edge with regard to customer service, many organisations are looking to improve their bottom line and financial performance by implementing new technology into their supply chains. A popular way for organisations to speedily reap the benefits of having a more competent and competitive, technology-enabled supply chain, is by outsourcing their supply chain needs to a third party logistics organisations. The Star newspaper reported that, according to Brett Bowes, inefficiencies in the supply chain meant that fast-moving consumer goods manufacturers and retailers were losing R7 billion every year (The Star, 16 March 2007; 2). Although there are many auxiliary benefits and advantages of implementing software systems into the supply chain, the two critical benefits which justify the expense are reduced costs and improved customer service. Implementing technology is a costly, challenging and sometimes risky endeavor. This often results in an unwillingness to change until these organisations outgrow their systems, or the business environment becomes so complex, that they are forced to implement new technology. This hesitancy to introduce new technology timeously could hamper the progress and growth of these organisations, and could also affect their competitiveness in a highly competitive environment. The purpose of this case study is to compare the benefits achieved from existing older technology to new technology, based on a routing and scheduling case study in a large 3PL organisation.

The effect of social media advertising on brand image of motor vehicles in South Africa

Hoeanat, Rethabile January 2018 (has links)
A research report Submitted in partial fulfillment of the requirements for the degree Master of Management in strategic marketing In the Faculty of Commerce, Law and Management at the University of the Witwatersrand Wits Business School, Johannesburg March 2018 / The automotive industry has experienced immense pressure as a result of global factors - inflation, competition, technology and political factors. Changing trends in consumer expectations have put the automobile industry under increasing pressure with more choices available. The practise of using Social Media Advertising by organisations and clients has revolutionalised the advertising and business landscape as it might be the most cost-effective way that organisations can promote their goods and services in the future. The marketing environment has evolved and marketers need to keep up and find innovative, cost effective ways to build brands. The main aim of this research was to examine the effects of Social Media Advertising on Brand Image of motor cars in South Africa. The study was grounded using 2 theories , AIDA (Attention, Interest, Desire, Action) and DAGMAR models. Social media involved the use of Facebook, Twitter, Instagram and Linkedin social media platforms. The study introduced the Keller Model of Brand Knowledge and investigated the relationship between Social Media Advertising, Brand Image, Types of Brand Associations, Benefits (Functional, Symbolic and Experiential) and Attitudes. The research design entails a quantitative approach and involves a cross sectional study design. The sample (N = 254) comprises owners and drivers of motor vehicles. A snowball sampling technique was used in selecting the final sample for the current study. This method was the most practical and feasible to arrive at the selected sample. The data involved a 2 phased approach. This study emphasises the use of Social Media Advertising in brand building strategies, particularly through social media platforms - Facebook, Twitter, Instagram and LinkedIn. The findings also suggest that through social media platforms consumers’ attitudes are influenced towards advertising, brands and intentions in forwarding messages to other users. The conclusions of this study have implications for brand managers. The study reveals practical value because it demonstrates that social media activities do have a positive effect on brands because they are supportive of the buying process. / MT 2018
