Towards a contingency theory of collaborative planning initiatives in supply networks

In recent years there has been increased interest in supply chain (SC) collaboration, as a process that promotes inter-company co-operation in different business areas. This paper focuses on collaborative planning initiatives adopted to support demand and supply planning in supply networks. Since companies implement several different forms of collaborative planning initiatives, this paper intends to examine the relevant contingency effects that lead firms to choose a precise collaborative planning initiative. Ten cases were analysed to investigate the research question. Results found indicate that specific contextual conditions – i.e. goals of the collaboration, demand elasticity, product diversity and supply network spatial complexity – can affect the level of the collaboration in collaborative planning initiatives. Three different levels of collaboration are identified (i.e. communication, limited collaboration and full collaboration) – depending on the level of integration (i.e. whether companies simply exchange data/information, or synchronise and jointly decide their plans) and multiplexity (i.e. the number of business areas involved in the collaboration). It emerges that, while the goals of the collaboration influence the level of integration between companies; the elasticity of demand can determine the level of multiplexity. Furthermore, the research found that product diversity (i.e. whether companies sell different products) and a high supply network spatial complexity could limit the level of multiplexity in the collaboration.     

Integration of manufacturing and distribution networks in a global car company – network models and numerical simulation

Global supply chain practices and their effects have received considerable attention over the last two decades. In the recent past, the need for integration across supply chains has been identified as a key for effective and efficient operations of supply chains. This is observed with the increasing trend of collaborative partnerships among supply chain partners. This paper presents an integrated approach for manufacturing and distribution networks within the supply chain system of a global car company. The paper shows that the integration of manufacturing and distribution networks creates the environment for effective planning of many components and execution/follow-up of those plans. These components include materials, resources, operations/activities, suppliers and customers. The main features of the integration include component integration at individual networks via use of a central warehouse. This integration reduces various interfacing steps between partners and enables representations of relationships (component precedence, parent-component and component-component). The proposed integrated model is numerically tested using past data from one of Japan's auto-makers, based in the emerging economy of Thailand. The paper concludes that the integrated supply network eliminates the need for interfacing of individual networks and enables simultaneous planning of many components as well as forward planning of supply components in global supply chain operations. It also shows that the integrated approach is capable of providing visibility, flexibility, and maintainability for further improvement in the supply network environment.     

The impact of supply chain analytics on operational performance: a resource-based view

This study seeks to better understand the role of supply chain analytics (SCA) on supply chain planning satisfaction and operational performance. We define the architecture of SCA as the integration of three sets of resources, data management resources (DMR), IT-enabled planning resources and performance management resources (PMR), from the perspective of a resource-based view. Based on the data collected from 537 manufacturing plants, we test hypotheses exploring the relationships among these resources, supply chain planning satisfaction, and operational performance. Our analysis supports that DMR should be considered a key building block of manufacturers’ business analytics initiatives for supply chains. The value of data is transmitted to outcome values through increasing supply chain planning and performance capabilities. Additionally, the deployment of advanced IT-enabled planning resources occurs after acquisition of DMR. Manufacturers with sophisticated planning technologies are likely to take advantage of data-driven processes and quality control practices. DMR are found to be a stronger predictor of PMR than IT planning resources. All three sets of resources are related to supply chain planning satisfaction and operational performance. The paper concludes by reviewing research limitations and suggesting further SCA research issues.     

Cloud computing and its impact on service level: a multi-agent simulation model

Supply chains are increasingly becoming more complex, making collaboration progressively difficult to establish and maintain. It is imperative to understand not only the consequences, but also the drivers of effective and efficient collaboration. In this study, we attempt to show how varying levels of collaboration impact service level and how cloud computing fosters these levels of collaboration. We introduce a framework detailing how cloud computing impacts three levels of collaboration: (1) information centralisation, (2) vendor managed inventory and continuous replenishment programmes and (3) business intelligence (BI) collaborative planning, forecasting and replenishment. In addition, we use multi-agent-based simulation to analyse how each level of collaboration (enhanced through cloud computing) impacts service level as measured by fill rate. Obtained results show that cloud computing can enhance all three levels of collaboration. Further, our results demonstrate that BI collaborative planning, forecasting and replenishment have significantly greater service level benefits in comparison to other collaboration levels.     

The performance impact of implementing Web-based e-procurement systems

As Web-based e-procurement has become an important business avenue for the improvement of inter-organisational process efficiency, its implementation for purchasing direct materials nevertheless implies establishing collaboration mechanism among supply chain participants based on the adopted Internet based infrastructure. However, the value of Web-based procurement to the supply chain participants remains an arduous task for researchers. This study proposes a Web-based e-procurement impact model based on supply chain orientation, which includes both operational and strategic impacts. Specifically, the strategic dimension is about partner relationship, and the operational efficiency dimension includes supplier performance, buyer performance, process integration, and process automation. To prove the proposed model's contribution, a questionnaire survey was conducted on 137 firms in Taiwan who have all participated in e-procurement related projects. The results verify that the electronic execution of purchasing activities improves both the operational efficiency dimension and the strategic dimension. Furthermore, partnership has a positive impact on supplier performance and buyer performance.     

A holistic view of knowledge integration in collaborative supply chains

New product development (NPD) projects offer a unique opportunity to examine knowledge integration themes in a collaborative network. We propose a finer grained view of knowledge integration mechanisms in collaborative supply chains. Specifically, we propose two different types of mechanisms that are in play within a collaborative supply chain; short-term knowledge sharing and iterative knowledge enrichment. Using data from a large and diverse set of 432 NPD projects, we investigate the effects of knowledge sharing and enrichment between firms and their collaborative network partners, on product concept effectiveness and process performance. Our findings suggest that knowledge sharing and enrichment are significant mechanisms for enterprise-wide knowledge integration in collaborative networks. In addition, upstream knowledge sharing and enrichment has a significant influence on both product concept effectiveness and manufacturing process performance, over and above the effects of downstream knowledge sharing and enrichment. The relationship of upstream and downstream knowledge sharing and enrichment on product concept effectiveness and process performance had varying effects based on the contexts of product type, stage in the product life cycle and project size, indicating a context-specific influence of knowledge strategies. The implication of our results on academic theory and managerial practice is offered.     

Arcs of supply chain integration

Integration is posited by many authors as a supply chain utopia. Indeed, it is claimed as being synonymous with supply chain management excellence. The primary aim of this research is to verify the link between supply chain integration and competitive performance. Detailed information collected via an 8-year international field study of 50 products and their associated supply chains subjected to an extensive statistical analysis provides rigorous insight into supply chain integration in practice. The breadth of supply chain integration significantly correlates with increased performance, yet in practice, the majority of supply chains are not well integrated. However, most supply chains seem to follow a popular route when seeking to enable seamless operations. This starts with enhanced internal effectiveness followed by upstream streamlining and then finally downstream integration. If practitioners are still struggling with supply chain integration, this research confirms that they are not unique in their predicament. Indifferent practice is indeed the norm. Fortunately, practitioners can follow the popular route established herein when seeking to improve integrative capability.     

Designing a collaborative supply-chain plan using the analytic hierarchy process and genetic algorithm with cycle-time estimation

Collaboration management has become a key issue for supply-chain management and can improve the overall production/manufacturing performance and value. This paper aims to conduct collaborative supply-chain planning and establish supplier selection, as well as production and distribution planning. This study uses an Analytic Hierarchy Process with Rough Sets Theory to establish a supplier purchasing value rating system. Also, a cycle-time estimation procedure is developed to effectively estimate the operating time of a collaborative supply chain. Assembly-line balancing technology is also introduced to guarantee smooth production and distribution in a supply chain. A multi-objective optimisation mathematical model, including purchasing value, cost, cycle time, and smoothness index, is constructed to complete the supplier selection and production-distribution planning. To efficiently solve this mathematical model, this paper proposes a genetic algorithm (E_ctGA) combined with a cycle-time estimation procedure. Finally, it presents a case study for validation. The results show that a better collaborative supply chain plan could be achieved by combining the proposed cycle-time estimation procedure.     

Current issues and emerging trends in supply chain management: an editorial perspective

Due to the ever-changing dynamics of today's global market place, it is necessary to examine upcoming future trends that may impact businesses. Supply chains are a valuable component of all business planning, and hence, they must be continuously monitored. This paper reflects on the views and contributions of various authors writing on the crucial issue of managing supply chains. Specifically, topics such as relationship quality, performance, integration, responsiveness, risk management strategies, agility, and incentive systems in supply chains are addressed.     

The potential of emergent disruptive technologies for humanitarian supply chains: the integration of blockchain,Artificial Intelligence and 3D printing

The growing importance of humanitarian operations has created an imperative to overcome the complications currently recorded in the field. Challenges such as delays, congestion, poor communication and lack of accountability may represent opportunities to test the reported advantages of emergent disruptive technologies. Meanwhile, the literature on humanitarian supply chains looks at isolated applications of technology and lacks a framework for understanding challenges and solutions, a gap that this article aims to fill. Using a case study based on the flood of Tabasco of 2007 in Mexico, this research identifies solutions based on the use of emergent disruptive technologies. Furthermore, this article argues that the integration of different technologies is essential to deliver real benefits to the humanitarian supply chain. As a result, it proposes a framework to improve the flow of information, products and financial resources in humanitarian supply chains integrating three emergent disruptive technologies; Artificial Intelligence, Blockchain and 3D Printing. The analysis presented shows the potential of the framework to reduce congestion in the supply chain, enhance simultaneous collaboration of different stakeholders, decrease lead times, increase transparency, traceability and accountability of material and financial resources, and allow victims to get involved in the fulfilment of their own needs.

Entrepreneurial SCM competence and performance of manufacturing SMEs

This study reviewed the literature and interviewed managers to discover the dimensions of a new construct called the entrepreneurial supply chain management competence of small and medium-sized enterprises. We measured entrepreneurial SCM competence in terms of five first-order constructs: innovation orientation, proactiveness orientation, risk-taking characteristics, relational capital, and coordination capability. We further proposed that this competence affects SMEs’ performance directly and indirectly via the firm's SCM strategies. A set of survey data collected from automotive OEM suppliers in five ASEAN countries was used to test the research model. Results show that the five constructs are important dimensions of entrepreneurial SCM competence, and that they affect performance indirectly. Our findings provide valuable insights about the enablers of an SME's SCM practices and their effects on firm performance.     

Technological collaboration patterns in solar cell industry based on patent inventors and assignees analysis

This study examines technological collaboration in the solar cell industry using the information of patent assignees and inventors as defined by the United States Patent and Trademark Office. Three different collaborative types, namely local (same city), domestic (different cities of the same country), and international collaboration, are discussed. The general status of solar cell patent collaborations, transforming trends of collaborative patterns, average numbers of assignees and inventors for three collaborative types, and international collaboration countries are studied. It is found that co-invented patents and co-assigned patents have both increased in numbers during the four decades studied, and that collaboration between technology owners is very low while the collaboration between inventors is active. Domestic collaboration is the main collaborative pattern for both assignee collaboration and inventor collaboration. The other two collaborative types show contrary trends: international collaboration has slowly risen in the past decades while local collaboration has dwindled. The US has the largest number of internationally collaborative patents worldwide, though such patents account for a low portion of total US patents. In contrast, China has a small total number of patents and internationally collaborative patents, however its international collaborative shares are higher. The international collaboration patents among countries are few. A co-assigned patent analysis indicates that the main international cooperation partner of the United States is Japan. Based on an international co-invented patent analysis, the main international collaboration partners of the United States are Britain, Japan, and Germany; and the United States is also the most important collaboration partner of China.     

Collaboration networks and collaboration tools: a match for SMEs?

Global patterns of industrial production have resulted in relocation of industrial operations groups in an effort to create new markets for mass and customised mass production. The collaborative effort between these dispersed teams increases the likelihood of combining ideas and knowledge in novel ways. Internet technologies enable these virtual collaboration networks to seamlessly engage in discussions that demonstrate a richness of perspectives when it comes to problem-solving and innovative idea-exchange. Indeed, knowledge creation and harnessing collective knowledge are salient features of collaborative networks (CNs) and this is witnessed by a new interest in these entities. However, small and medium enterprises (SMEs) display a difficulty in partnering and collaborating in global networks, especially since their technological infrastructure may be lacking. Given the widespread adoption of collaborative technologies in social contexts, this research seeks to examine how such informal interactions are facilitated in SMEs through Web 2.0 tools. Specifically, this paper seeks to contribute to existing literature by examining how Web 2.0 affects the collaborative effort in two SME CNs; this study demonstrated that the collaboration effort is amplified when Web 2.0 tools are available. Other parameters such as trust in other members’ ability; perception of usefulness; and enhancement of collective knowledge are seen as supporting the CN mutuality. In addition, it brings together the three diverse research areas of collaborative networks, internet collaborative tools and psychological barriers and enablers.

Integrated product design,shelf-space allocation and transportation decisions in green supply chains

In this paper, we examine a supply chain consisting of a manufacturer and retailer where the manufacturer undertakes greening efforts in terms of pack-size reduction and transportation cost reduction. The retailer decides on shelf-space allocation for the product. Both the players benefit from the greening efforts of the manufacturer. In such a setting, we examine strategic decisions of the players and compare and contrast the performance of the decentralised supply chain with the centralised supply chain. We also examine the effect of collaborative mechanisms by modelling two contracts in which the retailer offers a transportation cost reduction effort based contract and a two-part tariff contract. We find that the decentralised supply chain leads to lower greening efforts and shelf-space allocation decisions. We also find that the contracts improve pack-size reduction effort, transportation cost reduction effort and shelf-space allocation, while also improving the profitability of individual players. The findings demonstrate a scope for supply chain collaboration between manufacturer–retailer pairs in this setting. The paper uniquely combines three critical elements in supply chains, namely, product design, transportation and retailing decisions, and aims to provide insights into the decision making of players considering environmental waste and pollution. The paper also reflects consumer behavior and trade-offs that the supply chain players face.     

Lean management in the context of construction supply chains

Construction started its lean journey with learning from manufacturing. Unlike lean manufacturing, few studies to date have investigated lean construction in both breadth and depth, especially from the perspective of construction supply chains. The limited understanding of lean construction results in a research problem. This research aims to explore the implementation of lean principles in the context of project-based construction supply chains. It achieves its aim through an empirical investigation in the UK. A combination of quantitative and qualitative methodologies provides this research with validity and reliability. Lean principles are found applicable to both residential building projects and many other types of construction projects. It is also found that lean construction can be enhanced if it synergizes with supply chain collaboration. Another finding is that lean management has a significant impact on project performance. Nowadays, construction pursues best lean practices through both learning from manufacturing and developing its own paths. Similar to manufacturing, more and more construction projects adopt industrialised and standardised production and lean management with supply chain collaboration to become leaner. On the other hand, construction-specific management approaches and information technology (IT) tools are increasingly used in lean construction practices to maximise value and minimise waste.     

Effect of firm characteristics,supplier relationships and techniques used on Supply Chain Risk Management (SCRM): an empirical investigation on French industrial firms

Recent years have witnessed a focus on managing risks in supply chains. On the one hand, there are many cases where events like natural disasters, strikes and terrorism have significantly influenced the performance of organisational supply chains and in turn their competitiveness. And on the other hand, operational activities and strategic decisions of the firms (concerning, for e.g. supply, procurement, production, delivery, commercialisation, demand management, planning, etc.) can be different than expected and so create uncertainties. Uncertainties, whether they are external or internal, impact organisations leading to increased supply chain risk. Realising the potential implications of these situations on supply chain competitiveness, an attempt has been made to define risks and their sources and to identify the management that can help reduce the negative impact of risks on supply chains. In this paper, a framework for supply chain risk management (SCRM) is proposed and is applied using the data collected from 164 French companies, in manufacturing sector. The literature review, theoretical framework and empirical research undertaken in this work have led to identifying critical success management for SCRM. The focus of this paper is the inter-organisational management of supply chain risk: the collaborative relationship (with industrial and supply partners) can be considered as an efficient way to make SCRM. The paper finishes with a summary of the findings and conclusions, along with suggestions for future research projects.     

Innovative knowledge sharing,supply chain integration and firm performance of Australian manufacturing firms

A number of reports show that innovation in Australian manufacturing firms is declining. We propose that better knowledge sharing practices can assist these firms to become more innovative. In this paper, we examine this proposition by empirically testing the relationship between knowledge sharing practices within and between trading partners as a framework for integration, and testing for the effect of these practices on firm performance. Data were collected from 418 organisations in the manufacturing industry in Australia to assess the degree to which innovative knowledge sharing practices provide a competitive advantage to Australian firms. Structural equation modelling approach to data analysis was used. It was found that the three innovative knowledge sharing constructs (internal knowledge integration, knowledge integration with customers and knowledge integration with suppliers) were strongly inter-related, providing a case for knowledge-based integration of firms with their trading partners. Further, these three exogenous constructs collectively explained about a third of the variance in the endogenous construct (firm performance). The relationships identified provide support for the efficacy of knowledge-based collaboration as an innovation promoting higher firm performance levels. Managers of manufacturing firms in Australia specifically, and others more generally, can use this as a way to conceptualise how their firms can develop internal integration and collaborative relationships with their trading partners.     

Collaboration in humanitarian supply chains: an organisational culture framework

The purpose of this study was to determine the impact that institutional logics and, more specifically, organisational culture can have on humanitarian supply chain (HSC) collaboration. A framework was developed that explicates buyer–supplier collaboration in a humanitarian setting. Twenty-nine semi-structured interviews were conducted with buyers and suppliers. The data indicated that in a HSC, collaborative outcomes, such as new product development, inventory management, and product/service delivery, are influenced by the buyers’ and suppliers’ organisational cultures. Based on suppliers’ characteristics, they can be classified as humanitarian suppliers, commercial suppliers, and humanitarian and commercial suppliers. These groups have distinct organisational cultures. An unexpected finding is that suppliers that serve commercial buyers primarily claim to have encountered no issues in supply chain collaboration with humanitarian buyers, although they have different types of organisational cultures. The factors that lead to successful collaboration are identified as trust, commitment, information sharing and mutual respect. Simultaneously, dominant institutional logics are observed in the dyadic relationship.
