Models for evaluating and improving delivery performance play an important role in the management of supply chains. A review of supply chain delivery models that use Six Sigma methodologies indicate that the models are limited to only make-to-order supply chains where improvement in delivery performance occurs at a fixed (static) point in time. In this chapter, the authors present a generalized delivery performance model that overcomes these limitations. The model presented here can be used to measure delivery performance in both make-to-order and make-to-stock supply chains and supports improvement in delivery performance over a planned time horizon with definable milestones for attaining targeted levels of improvement. Numerical illustrations of the model are presented.

Novel Approach

PurposeThis paper aims to depict the practical execution of the problem-solving structure provided by the define, measure, analyze, improve and control (DMAIC) framework in combination with the analytical power provided by process mining capabilities, to improve the supply chain quality of a health-care provider. Design/methodology/approachPrior to the study, a literature review was conducted to identify existing frameworks combining six sigma with process mining. The authors use a descriptive case study approach to explain how the two methodologies blend across the different phases of DMAIC in a health-care setting. FindingsThis case study describes how analyzing data extracted from core information systems has significant value to improvement initiatives when complemented by traditional quality methods. By intersecting process mining techniques with lean six sigma tools, the researchers found 65% of orders not complying with the target ordering time and 200 redundant purchases with high operational costs. Research limitations/implicationsBy depicting how the two methodologies can be intertwined, this paper complements existing research by presenting it as a viable quality improvement approach. Practical implicationsThis paper provides insights for six sigma and process mining practitioners on the benefits of combining both methodologies within the DMAIC structure. Implementing this blended approach can bring visibility to operations and accelerate process improvement initiatives. Originality/valueThe prime value of this paper lies in the integration of traditional six sigma methods with process mining as a technological approach in a health-care context, going beyond existing research, which, to the best of the knowledge, lacks descriptive case studies.

PurposeModern supply chains are at risk as a result of increasing disturbance. The use of Lean and Six Sigma’'s values, methods and tools can be one option to analyze, prevent and mitigate risks. The purpose of this study is to investigate whether a combined Lean Six Sigma philosophy can support the awareness and management of supply-chain risk.Design/methodology/approachThe methodology followed in the study is based on a literature review and multiple case study, performed by means of qualitative methods of data collection, such as observations on-site, face-to-face interviews and document analysis. Case selection includes the results of research conducted in seven large Swedish companies.FindingsIt has been indicated that Lean and Six Sigma values, methods and tools can be very effective in companies’ efforts to control the supply-chain risks and that they improve the companies’ ability to handle variability and risk management. Lean Six Sigma supports a risk-management culture in the focal companies, but they must involve customers and companies in the supply chain if they wish to create a risk-management culture in the entire supply chain. In order to do this, they can use the Six Sigma training structure, but they need to include more risk tools and methods developed for the supply chain management. It has also been indicated in the literature that if more people involve in 6S projects, the financial results will be better, and the innovation of processes will increase.Research limitations/implicationsThese include suggestions for how the companies can use the Six sigma training structure to collaborate in the supply chain.Practical implicationsThis study gives practical suggestions for how the companies in supply chain can collaborate and use the Six Sigma training structure for creating a more holistic view of supply chain, which also decrease risks in supply chain.Originality/valueThis study indicates that Lean Six Sigma supports risk awareness and management in the focal companies of the supply chains, which improves companies’ ability to handle variability and risk management. It has also been demonstrated that the companies should use the Six Sigma framework, especially training, as a foundation, and they should create common projects for better collaboration in the supply chain, which will decrease the risks in the entire supply chain.

The article reveals the main trends in the functioning of global supply chains in the context of the COVID-19 pandemic and their impact on the activities of Ukrainian enterprises are identified. It is noted that the closure of borders between countries and the introduction of self-isolation regime caused a significant reduction in production capacity and the volume of international trade. Global supply chains have become very vulnerable and necessitate their revision and the search for alternative ways to deliver goods to end users. Since Ukraine is a country with an open market economy, this article summarizes the main challenges for import-dependent supply chains and makes proposals on ways to overcome them. The expediency of applying the concept of Lean-management in business processes management of refrigeration supply chains during a pandemic as a means of overcoming crisis situations and ensuring sustainable development are proved. The dynamics and structure analysis of the company LLC "Holod Engineering" income and expenses allowed to establish a tendency to reduce the profitability of the company's business and capital turnover, as well as increase the share of logistics costs in the production costs. The greatest impact on the growth of logistics costs have the inventory costs due to the processes of storage and orders completion and delivery delays, which lead to customer dissatisfaction and complaints. Methodical approaches to estimating the level of processes coordination in the supply chains of refrigeration equipment, calculation of supply lots optimal parameters, levels of raw materials and components stocks, production and storage capacity rationalization of the enterprise are substantiated. With the help of Shewhart's control charts, the coordination of business processes in the equipment supply chains were assessed and the sources of potential losses were identified. The technological and logistics processes optimization in terms of their cost, duration and quality of results takes into account not only individual processes of enterprises, but also interprocess connections between supply chain links. It is proposed to implement a number of organizational measures using the concept of lean management, which involves market integration, production process, procurement and sales in order to provide a high level of customer service. The efficiency of the proposed organizational changes and their impact on business profitability, inventory turnover, the amount of logistics costs and the quality of customer service are determined.

Astrans Putra Logistik Ltd. is a logistics service company with shipping routes in Sidoarjo, Denpasar, Lombok and NTB. Some of the problems that occur, such as delays in the pick-up process of goods to the load that large but not enough for departure, cause the quality of the supply chain system to be poor. So this research needs to be done with the aim of knowing the point of waste in the supply chain, identifying the sigma value, and determining the priority for its improvement. Quality improvement is carried out using the Lean Six Sigma method with AHP integration as a priority selection for improvement. From the research results, it was found that there was waste that caused 3 (three) CTQ, namely delivery was delayed, goods were damaged or leaked, and there was a difference in the number of goods. The company's DPMO value is 34272 with a sigma value of 3.34. The priority for improvements that can be made based on AHP weight, namely check the package packages before they are sent (0,353), make SOP for the preparation of goods (0,167), and apply SOP for goods checking documents (0,142).
