The supply chain faces uncertainties, especially with the flow of products and information that may affect the productivity, revenue and competitive advantages of many organizations. It is therefore necessary for these organizations to be agile and resilient enough to meet with these uncertainties so that they may be managed appropriately or even avoided. In a publication by Mensah et.al (2014), the authors introduce a theoretical approach where the „conceptualization of risks for subsequent simulation-based analysis‟ is evaluated. This includes the description of „a generic conceptual model of a retail node‟ followed by the introduction of performance indicators relevant for simulation base analysis. Hence, a concept for further studies from a practical point of view has now arisen. This article therefore introduces a new case study where the flow of products in a real company is conceptualized for simulation base analysis to raise the awareness of the organization in case of uncertainties.

In recent years, logistics outsourcing has shown a strong development. However, despite the benefits associated with logistics outsourcing, there are many relationships that do not last as long as they were initially planned. In this chapter the authors tried to sketch a conceptual model of Risk Management applied to logistics outsourcing and supported by a case study within aerospace industry. Their results show that Risk Management could be an innovative tool favoring the success of logistics outsourcing by securing future performance and relationships between supply chain partners.

Web technology has enabled many organizations to form an e-enterprise for effective communicating, collaborating, and information sharing. To gain competitive advantages, it is necessary for e-enterprises to integrate the entire lines of business operations and critical business data with external supply chain participants over the Web, which may introduce significant security risks to the organizations’ critical assets and infrastructures. This chapter reports a case study of e-service security design and implementation at a leading U.S. company. First, the chapter reviews security concerns and challenges in front-end e-business and back-end supply chain operations. This is followed by the analysis of the company’s e-service and its security problems. The case then presents an integrated e-enterprise security methodology to guide the company for meeting its security needs. The results of this case study provides security professionals with practical steps and sustainable solutions for tackling the unique security challenges arising in an open, unbounded e-enterprise supply chain environment.

Due to the nature of the manufacturing and support activities associated with long life cycle products, the parts that products required need to be dependably and consistently available. However, the parts that comprise long lifetime products are susceptible to a variety of supply chain disruptions. In order to minimize the impact of these unavoidable disruptions to production, manufacturers can implement proactive mitigation strategies. Two mitigation strategies in particular have been proven to decrease the penalty costs associated with disruptions: second sourcing and buffering. Second sourcing involves selecting two distinct suppliers from which to purchase parts over the life of the part’s use within a product or organization. Second sourcing reduces the probability of part unavailability (and its associated penalties), but at the expense of qualification and support costs for multiple suppliers. An alternative disruption mitigation strategy is buffering (also referred to as hoarding). Buffering involves stocking enough parts in inventory to satisfy the forecasted part demand (for both manufacturing and maintenance requirements) for a fixed future time period so as to offset the impact of disruptions. Careful selection of the mitigation strategy (second sourcing, buffering, or a combination of the two) is key, as it can dramatically impact a part’s total cost of ownership. This paper studies the effectiveness of traditional analytical models compared to a simulation-based approach for the selection of an optimal disruption mitigation strategy. A verification case study was performed to check the accuracy and applicability of the simulation-based model. The case study results show that the simulation model is capable of replicating results from operations research models, and overcomes significant scenario restrictions that limit the usefulness of analytical models as decision-making tools. Four assumptions, in particular, severely limit the realism of most analytical models but do not constrain the simulation-based model. These limiting assumptions are: 1) no fixed costs associated with part orders, 2) infinite-horizon, 3) perfectly reliable backup supplier, and 4) disruptions lasting full ordering periods (as opposed to fractional periods).

Abstract On the world stage, Brazil is the third largest world fruit producer. However, purchasing fruit companies are suffering from the effects of fluctuations in production and demand, inefficiency in production and information trade, lack of understanding of the dynamics of supply and reduction in profitability for all members of the fruit production chain. The supply chain management has been touted as one of the ways to reduce this volatility and improve outcomes for all involved with the supply chain. However, results of recent researches do not relate it directly to the fruit industry. To solve this problem, the present research aimed to analyze the planning and management of the supply chain of a fruit purchasing company and identify contributions and improvements to the theories and methods related to supply chain management to propose a method for planning and management the supply chain of fruit purchasing companies. It was conducted a case study from a mango fruit purchasing company using interviews with industry experts to assess the applicability, functionality and usefulness from the managerial point of view of the proposed method. Data analysis was done through the cross analysis of the methods of the supply chain management and the description of the case. The results of the study allowed the development of a method for planning and management the supply chain of fruit purchasing company. With the proposition of this method is expected to contribute with a sequence of steps to assist in planning and management of supply chain managers and specialists from a fruit purchasing company.

PurposeThe purpose of this paper was to investigate what types of supply chain strategies (SCS) are implemented within luxury fashion companies, according to the drivers that regulate competitiveness in this sector (brand positioning, distribution channel, type and line of product). Moreover, the objective was to define which key performance indicators (KPIs) should be measured according to the chosen strategy, and finally to evaluate the alignment of luxury fashion companies with the proposed indicators.Design/methodology/approachThe literature review was the first step performed. Thereafter, a case study was conducted and the sample, composed of six companies, was selected, a questionnaire was then developed to guide the interviews, after which the data were collected. From the data, a primary case analysis was conducted, from which cross-case patterns were also researched.FindingsFrom the results obtained, it was possible to state that companies involved in the case study adopted different SCS within the same company according to the drivers that regulate the sector competitiveness. As a result, the product line was shown to be the only driver that affected both the alignment between the expected and implemented SCS, respectively, and the alignment with the selected KPIs.Originality/valueThe paper provides valuable insights to companies that are trying to align SCS and KPIs. The close link between these aspects had not yet been explored previously. In particular, there were no indications about the KPIs that have to be measured for a specific SCS.

Purpose Numerous and diverse organizations have implemented lean principles and practices, which concentrate on improving the efficiency of business processes by reducing cost, waste, consumptions and effort. However, previous assessments have not focused on the leanness of the supply chain in a health-care setting. This paper aims to introduce a method for assessing the successful implementation of lean principles and tools in a supply chain. Furthermore, this paper validates the method in a health-care organization. Design/methodology/approach This paper starts with an extensive literature review on assessing leanness and using multi-grade fuzzy logic. Then, a conceptual model was developed to measure leanness. The conceptual model was validated by discussing the initial version with select academic experts, especially those who deal with leanness in health-care organizations. After responding to the experts’ valuable comments, the health-care organization that is the focus of this case study was chosen based on two criteria. The first criterion was the organization’s ability to participate in the study, and the second was the organization’s commitment to implementing lean principles. These criteria were important to ensure the organization had the necessary foundation for implementing change initiatives such as lean process improvements. Next, a multi-grade (multi-attributes) fuzzy logic was used for leanness measurement. A leanness index was calculated, and the results were validated using experts from the case study organization. Finally, the weaker areas of the organization’s processes were identified to point the way for further improvements. Findings The assessment indicated that the case study organization is not lean. The organization’s weaker attributes were identified, and improvements have been suggested. Research limitations/implications This study focused on a single health-care organization, which was selected from a limited pool of potential organizations, namely, organizations which are accredited by both the Saudi Central Board for Accreditation of Healthcare Institutions and the Joint Commission International. The scope of future research should be extended to multi-case studies to enhance the findings presented in this paper. This paper’s findings can be used to help decision-makers at health-care providers to implement lean thinking in supply chain processes. Practical implications This research may be interest to practicing supply chain managers, as it proposes what enablers, factors and attributes should be emphasized in lean implementation. The proposed model can work as an assessment tool to identify the gap between the present level of leanness and the desired leanness state so the health-care organization can identify what can be improved. This model enables decision-makers in hospital supply chain to take suitable actions for improving lean implementation level. Originality/value This study makes an original contribution to the body of research concerning lean principles; the study developed a conceptual model for leanness assessment that can be applied to the supply chain of health-care organizations. Indeed, the conceptual model is likely to be useful for assessing leanness outside of the health-care field, which suggests avenues for future research.

The failure in 1697 of the ‘Malt Lottery’, the second lottery loan, presents a fruitful case study. From a practical point of view, it tells us three things. First, the technical features of the English state lottery loans were established for more than a century after only three experiments. Second, its two components (‘lottery’ and ‘loan’) led to an abnormally poor return for investors since its expected return was 3.91 per cent whereas its effective return was 5.84 per cent – two figures in contradiction with the 6.3 per cent advanced by Dickson (1967). Third, a most strange solution was devised to counteract the failure: delivering the unsold tickets to the Exchequer to be used as cash. From a more theoretical point of view, the condition North and Weingast (1989) advanced for a successful financial issue proves necessary but not sufficient. The Malt Lottery failed (1,763 tickets sold out of 140,000) because it did not meet the three requirements for success: its return was too low and was lower than the return on competitive assets; its reimbursement dates were uncertain; and the economic and political environment was gloomy.
