- This paper presents a decision-support system for reshoring decision-making based on fuzzy logic. The construction and functionality of the decision-support system is briefly outlined and evaluated in a highcost environment contemplating six specific decision criteria, namely cost, quality, time, flexibility, innovation and sustainability. A major challenge with fuzzy logic solutions has to do with the construction of the fuzzy inference rules. In the relocation domain, the fuzzy inference rules represent the knowledge and competence of relocation experts and they are usually created manually by the same experts. One obstacle is that the complexity of the fuzzy inference rules increases with the number of decision criteria. To overcome this complexity issue, this paper presents a solution whereby the fuzzy inference rules are automatically generated by applying one hundred reshoring scenarios as input data. The reshoring decision recommendations produced by the fuzzy logic decision-support system are demonstrated to be close to those of human reshoring domain experts.

Reshoring decision support in a Swedish context
- 2018
-
Konferensbidrag (refereegranskat)abstract
- This paper presents a decision-support system for reshoring decision-making based on fuzzy logic. The construction and functionality of the decision-support system are described, and the functionality is evaluated in a high cost environment exemplified through a Swedish context. Ten different reshoring scenarios, provided by Swedish reshoring experts, are entered into the decision-support system and the decision recommendations provided by the system are presented. The confidence that can be put on the recommendations is demonstrated by comparing them with those of the reshoring experts. The positive results obtained indicate that fuzzy logic is both feasible and that the quality of the results are sufficiently good for reshoring decision-making.

- Reshoring can be regarded as offshoring in reverse. While offshoring mainly has been driven by cost aspects, reshoring considers multiple aspects, such as higher quality demands, faster product delivery and product mass-customization. Where to locate manufacturing is usually a purely manual activity that relies on relocation experts, hence, an automated decision-support system would be extremely useful. This paper presents a decision-support system for reshoring decision-making building a fuzzy inference system. The construction and functionality of the fuzzy inference system is briefly outlined and evaluated within a high-cost environment considering six specific reshoring decision criteria, namely cost, quality, time, flexibility, innovation and sustainability. A challenge in fuzzy logic relates to the construction of the so called fuzzy inference rules. In the relocation domain, fuzzy inference rules represent the knowledge and competence of relocation experts and are usually generated manually by the same experts. This paper presents a solution where fuzzy inference rules are automatically generated applying one hundred reshoring scenarios as input data. Another important aspect in fuzzy logic relates to the membership functions. These are mostly manually defined but, in this paper, a semi-Automatic approach is presented. The reshoring decision recommendations produced by the semi-Automatically configured fuzzy inference system are shown to be as accurate as those of a manually configured fuzzy inference system.

Mitigating transportation disruptions in a supply chain : a cost-effective strategy

- Transportation disruptions can be damaging to a supply chain because goods may not arrive on time and this jeopardises the service level to the customers. While supply chain disruptions have gained significant attention from scholars, little has been done to explore these disruptions in the context of transportation. The study described in this paper aims to address disruptions occurring in the transportation of goods from a plant to a distribution centre. We modelled this real case to obtain insights on the effectiveness of different strategies to mitigate transportation disruptions. We evaluated four mitigation strategies and compared the outcomes in terms of service level and total costs: (1) the risk acceptance strategy, (2) the redundant stock strategy, (3) the flexible route strategy, and (4) the redundant-flexibility strategy. The results suggest that the best strategy differs depending on the budget that managers are willing to deploy to improve the service level. The simulation experiments and the use of the Incremental Cost Effectiveness Ratio (ICER) would be instrumental in helping decision makers in selecting the best disruption mitigation strategies where the best option would likely be different under varying circumstances.

Lean implementation in geriatric care in a municipal : A case study from Sweden

Konferensbidrag (refereegranskat)abstract
- Purpose: The aim of this research is to examine how lean has been implemented at geriatric care in a municipal department in Sweden, focusing on the experiences and challenges of the employees, together with the strengths and weaknesses of the lean philosophy.Design/methodology/approach: The primary method used was a case study with interviews and observations on spot, in combination with a literature study. All with the intention of defining and describing lean, its value, and how organizations generally apply lean.Findings: All sources of information have shown that there are many advantages with lean such as better communication and a better-organized workplace. In addition, lean tools help to eliminate non-value adding activities (waste). However, implementations also bring about issues and challenges such as the difficulty of creating a long lasting lean commitment. A lack of follow-ups and the decreasing demand for lean from the executives have been the main issues within the geriatric care. The next step might be to create a common organizational culture, which is permeated with continuous improvements, focusing on value-adding activities for the residents and others stakeholders.Originality/value: Very few studies have addressed lean implementation in geriatric care as well as in a municipal department.

- The aim of this research is to examine how lean has been implemented in the geriatric care sector in a municipality in Sweden. The research focuses on implementation experiences and challenges encountered. The research method used is a case study using interviews and observations for data collection. The findings indicate that there are many advantages of lean in the geriatric care sector, such as better communication, organisation and workflow. The lean implementation worked as an eye-opener and created a situation, where the employees realised a great deal of waste in the daily operations. In addition, lean tools helped to reduce the waste. The findings also indicate that there are some challenges of lean in the geriatric care sector, such as the difficulty to create long-lasting lean commitment. A lack of follow-ups, decreasing interest from senior management and lack of a holistic view were the main issues in the case organisation.

- Purpose: The aim is to examine if the joint-use strategy of Lean Six Sigma can improve flexibility, robustness, cost-efficiency, and agility at the same time.Design/methodology/approach: A single case study including a Swedish company from the telecom manufacturing industry was conducted.Findings: A Lean Six Sigma strategy ensures more flexible, robust, and efficient processes. However, to make them agile, something more is required. This could include training the staff, strengthening company culture and collaborating with key partners in the supply chain.Research limitations/implications: This study is limited to large companies that usually have a lot of resources and choices where to put the strategic emphasis. The situation could be very different in small and medium-sized companies.Practical implications: This research provides guidance on how to manage the Lean Six Sigma strategy in order to ensure more flexible, robust, and efficient processes.Originality/value: This research provides guidance to companies regarding the applicability and properties of the Lean Six Sigma strategy.
