Article
Supply chain integration is widely considered by both practitioners and researchers a vital contributor to supply chain performance. The two key flows in such relationships are material and information. Previous studies have addressed information integration and material (logistics) integration in separate studies. In this paper, we investigate the...

Purpose The purpose of this paper is to present and test a new model for competitive capabilities. Traditionally, a cumulative model has been viewed as having one sequence of building competitive capabilities in a firm in support of market needs, including quality, delivery, cost efficiency and flexibility. Although appealing as a conceptual model,...

Full-text available
In order to compete successfully, operations in any type of firm need to be strategically aligned to the market requirements. This concerns both manufacturing and supply chain operations. The customer order decoupling point (CODP) is getting increasing attention as an important input to the design of manufacturing operations as well as supply chain...
Chapter
The concept of a customer order decoupling point (CODP) has been discussed since 1984. The CODP refers to the point in the supply chain at which a product is linked to a specific customer. Consequently, make to stock (MTS), assemble to order (ATO), make to order (MTO), purchase and make to order (PMTO), and engineer to order (ETO) all refer to diff...
Chapter
Global supply chain management concerns the management of sourcing, manufacturing, and distribution that take place in different countries before a product is sold and delivered to the final buyers. From the view of the focal manufacturing firm, a global supply chain consists of three key parts: the upstream supply network, the manufacturing networ...
Presentation
Aims The paper describes efforts to understand and work towards supply chain visibility (SCV): enumerating factors influencing its implementation, information that should be shared for better visibility and evaluating different technologies that can facilitate SCV. It summarises findings from different studies conducted during the research project...
Article
This study aims at investigating the influence of contingency factors on the drivers of offshoring and backshoring decision processes. A case survey of existing case studies on backshoring was performed with qualitative comparative analysis (QCA). In total, 43 cases from 16 research papers were analyzed. The results showed that many factors act as...
Article
Full-text available
Supply chain visibility (SCV) has been gaining recognition in recent years as a key factor for achieving analytical capabilities and improving supply chain performance. However, levels of SCV implementation lag behind current technological advances. This research was motivated by the lack of visibility in inbound logistics, which limits the possibi...
Article
Full-text available
Visibility across supply chains has been a key concern for organisations for many years, but the tools and information systems to achieve real-time visibility have not been available until recently. In response to uncertainty and complexity, advanced information and communication technologies have been explored for supply chain visibility (SCV). Ho...
Article
Full-text available

This paper is concerned with the management of multi-plant manufacturing networks. Two key concepts in this domain are plant roles and plant autonomy in the context of operations strategy decision-making. We investigate the relationship between these two concepts and their impact on plant performance. We use data from 102 manufacturing plants belon...
Chapter
Events such as Covid-19 have revealed the vulnerabilities that companies face due to low visibility. Consequently, companies experience impact on their supply chains in terms of disruptions of material supply, deliveries, productivity and revenue. Thus, the importance of Supply Chain Visibility (SCV) in global and competitive markets with increasin...
Chapter
Visibility in production logistics and across the supply chain has become a key concern for organizations. Its need has been further emphasized due to the current COVID 19 crisis. Organizations find it challenging to prepare the internal logistics and supply chain, and quickly respond to such unexpected events, due to low visibility. Against this b...
Article
We address how to manage extended supply chains that lie beyond the first‐tier suppliers. The first‐tier suppliers have their suppliers who provide them with goods or services. While lower‐tier suppliers are often not an explicit concern of the focal firm, the firm's performance not only depends on the performance of its first‐tier suppliers, but a...

Globalisation, competitive markets and increasing sustainability requirements are demanding companies to focus on visibility to improve their supply chains and ultimately their businesses. This paper aims to identify perspectives, principles and prospects of production logistics visibility (PLV). The study is based on a literature review of article...
Conference Paper
This study is built on a quantitative meta-analysis of already existing reshoring case studies. Case studies have been popular in this research stream, given its still exploratory stage. They usually provide rich insights through qualitative data, but in this study, they have been codified into quantitative data, thus allowing to make statistical i...
Article
Full-text available
When manufacturing firms are deciding which products to produce, it is of utmost importance that they correctly allocate costs to products. It is common practice for manufacturers to use a single model for cost allocation and management accounting and to apply it to all products and production resources. Since most organisations have different type...
Article
Full-text available
Manufacturing firms with multiple product groups do not need to involve all factories in the production of all product groups. Some factories may specialize on a small set of products, while others participate in the manufacturing of a broader set of products. However, current theories on international manufacturing networks do not explain in detai...

Article
Full-text available
The global nature of businesses has increased the geographical dispersion of operations and has made the location decision an important strategic perspective for manufacturing firms. The consensus view is that three major plant location factors must be kept in mind: (1) access to low-cost manufacturing, (2) proximity to market, and (3) access to de...

All supply chains are not the same. A key factor that affects the design and management of a value chain is the position of the customer order decoupling point; some products are produced to order (e.g. configured to particular customer needs) while others are produced to stock (typically standard products). The customer order decoupling point (COD...

Strategic decision-making is often based on conceptual and qualitative models. Considering the vast amount of quantitative models in the literature, it is most interesting and important to explore the possibilities to expand the modelling base for decision-making with quantitative models that can provide deeper analysis, new insights and allow for...
Article
Firms using industrial goods as a resource in their own operations need support and services to maintain the efficient use of these resources. The prevailing trend is to integrate goods and services in a product package. We take the supplier's view on the task of providing industrial services, i.e. the supply of after-sales services, including tang...
Article
All value chains are not designed the same way. A major determinant is the type of product that is to be supplied through the chain or network, calling for different types of value chains. An interesting model for this selection is the one developed by Fisher, arguing that products can be characterised as being either functional or innovative, and...

Safety stocks can be introduced in different ways in production and inventory control systems. The three basic types are physical safety stock, safety lead time, and hedging. Departing from the formula for calculating the number of kanbans, it is shown that all three approaches are implicitly incorporated in the kanban safety mechanism approach. Di...

In a note by Rosling (1994) he pointed out that the model presented in the paper “Balancing capacity and lot sizes” in European Journal of Operational Research (1985) can be viewed as an approximate queueing model and that the results of the model in such a context can lead to inappropriate interpretations. However, the model was not developed as a...
