Abstract

An emerging synthesis between natural and social sciences is discussed and the new science of “chaos” which originates in chemical researches is introduced. Educational systems are seen to be dissipative structures allowing analysis of them in “chaotic” terms. Such structures have a self‐organising dynamic which produces “second order” changes to a new regime. This has long been associated with analysis of leadership. The creative input of a single individual, though small, may lead to far‐reaching effects if guided by vision.

Abstract

Purpose

The paper aims to study the challenges and solutions of city logistics in the new retail era. The new retail, which is characterized by omni-channel, fragmented orders and decentralized 2C distribution, is becoming the mainstream of the retail industry worldwide. In order to achieve a comprehensive breakthrough in new retail, the change of order fulfillment mode is the most noteworthy issue. The aim of this paper is to design a city logistics operation model for new retail and verify its feasibility and efficiency.

Design/methodology/approach

A physical internet (PI) enabled two-tier city logistics solution is proposed by redefining the key facilities in city logistics with the PI concept. A “Container-as-a-Warehouse” operation mode is designed to provide a more flexible store and transfer solution. A mathematical model of the proposed solution is established. An adaptive large neighborhood search (ALNS) is designed based upon an iterative procedure, which ensures consistent and optimal results.

Findings

To quantitatively assess the feasibility of the proposed solution, a computational experiment is designed to compare the performance of the proposed model against the conventional two-tier city logistics operation. The effects of geographical location pattern, utilization of PI-hub as well as the fluctuation of customer orders are analyzed. The results show that the PI-enabled city logistics is more advantageous than the conventional solution.

Research limitations/implications

This study does not consider the impact of new technologies in city logistics; for example, the replenishment problem of unmanned vending machines and the charging problem of electric vehicles.

Practical implications

The proposed PI-enabled solution and analysis results in this paper have positive guiding significance for future practical application.

Originality/value

Based on the concept of PI, this paper proposes an innovative and practical operation model to solve the city logistics challenges.

Abstract

Purpose

The popular “beer game” illustrates the bullwhip effect where a small perturbation in downstream demand can create wild swings in upstream product flows. The purpose of this paper is to present a methodical framework to measure the bullwhip effect and evaluate its impact.

Design/methodology/approach

This paper illustrates a framework using SKU-level data from an industry-leading manufacturer, its distributors, end-users and suppliers.

Findings

Firms benefit from tracking multiple intra-firm bullwhips and from tracking bullwhips pertinent to specific products, specific suppliers and specific customers. The framework presented in this paper enables managers to pinpoint bullwhip sources and mitigate bullwhip effects.

Research limitations/implications

This paper presents a framework for methodically measuring and tracking intra-firm and inter-firm bullwhips.

Practical implications

A disconnect exists between what is known and taught regarding the bullwhip effect and how it is actually tracked and managed in practice. This paper aims to reduce this gap. For the various products analyzed herein, the authors show how using this framework has the potential to reduce delivered product cost by 2 to 15 per cent.

Social implications

Properly managing the bullwhip leads to lower inventories and potentially lower product prices while simultaneously increasing firm profits.

Originality/value

This paper presents a novel approach to systematically tracking intra-firm bullwhips along with bullwhips specific to a given supplier or customer.

Abstract

THE Treaty of Rome is one of the least publicised, yet potentially most important, international documents of our time. Under that treaty the six signatory powers began on the first day of this year that process of tariff reductions which will, over the next twelve or fourteen years, reduce and ultimately abolish all tariffs and trade barriers between them. For all practical purposes six national economies will be welded into a single supranational authority, with a common trade and commercial policy. That is to re‐draw the economic map of Europe.

Abstract

Agile manufacturing is a response to competition in environments characterised by unpredictable change, so having the ability to vary capacity, respond to sporadic changes in demand, mass customise at the cost of mass production, and compete in both mass and custom markets is crucial. Empirical justification of the benefits of implementing agile manufacturing is rare in the literature and an in‐depth empirical study of the benefits of implementing agile manufacturing practices is lacking. This article aims to address this gap by conducting a preliminary analysis of a much wider empirical research. The adoption and impact of a set of tools – enablers of agile manufacturing – were studied through a survey by questionnaire. The results show lower volume flexibility at higher levels of adoption of the five enablers, thus the resource competencies for enhancing it were not in place. Also, volume flexibility ranked very low in hierarchy of future improvement plans. Suggests virtual cells, and its extension into supply chain networks, as a solution to volume flexibility.

Abstract

Purpose

The purpose of the paper is to explore the practices with logistics performance management in two textiles supply chains, and to identify the related best practices and barriers.

Design/methodology/approach

The method is a multiple case study of two textiles supply chains with a special focus on the rarely addressed interface between the manufacturer and the retail chain. The retail chains represent one large, global retail chain and one Nordic, comparably smaller retail chain. This paper is primarily empirical and describes practices for logistics performance management. The analysis discusses and explains best practices and barriers for logistics performance managements in textiles supply chains.

Findings

Differences were identified regarding practices, priorities and collaboration in the logistics performance management process. No textiles industry-specific practices were found. A way of exchanging action plans between the actors is an interesting best practice, which enables improvement projects even with long geographical distances. Barriers in the shape of difficulties in creating a collaborative culture were found; however, IT support seems no longer to be a barrier.

Research limitations/implications

Two cases are explored, why a broader study is necessary to confirm the results. The best practices and barriers identified are similar to those known from manufacturing companies.

Practical implications

The detailed descriptions of logistics performance management practices can provide insights for practitioners. Even if the studied supply chains are important for the respective actors, there is a potential for increased effectiveness in textiles supply chains.

Originality/value

Supply chains for textiles products “starting at a manufacturer and ending in a retail chain” seem to be an unchartered territory and not many studies have been performed.

Abstract

Purpose

The purpose of this paper is to describe the characteristics of complexity and how a retail supply chain can contain complexity in itself. A case has been provided to show the measurement of complexity with/without information sharing and the relation of complexity with the performance measures. Quantification of the complexity will help the practitioners to take strategic actions.

Design/methodology/approach

System dynamics simulation has been used to model the retail supply chain with and without information sharing and data visibility. Entropy-based metric used for quantification and comparison of complexity based on the outputs of the models. Performance measures proposed for the retail supply chains to understand the effect of data visibility.

Findings

Paper provides insight about the complexity of retail supply chain perspective. Using system dynamics modelling can be a useful way to perform what-if type analysis before business process changes. Including both complexity and performance measures can be useful to understand if the complexity is good or bad for the business and if it is in manageable amount.

Research limitations/implications

Paper can encourage the future research on retail supply chains.

Practical implications

Approach can be useful to analyse what-if type analysis in practice easily. It can support strategic decision making process.

Originality/value

Combines retail supply chain with complexity and performance measurement.

Abstract

Both practitioners and research scientists have noted a number of problems regarding measurement activities during the past decade. The problems reported suggest that measurement activities are fragmented both within and across organizations. Expands on a systems perspective on supply chain measurements and describes how problems can be communicated, understood and managed by developing methods and tools for describing interrelationships within supply chains. Empirical evidence from a case study of a Swedish home furnishing business supply chain provides data suggesting that firms within a supply chain cannot simply be categorized as either having adopted systems thinking or not. Rather, both structured models indicating a high degree of systems thinking, and problems showing fragmentation, are present. A performance model, which is used to reflect the systemic structure of an underlying supply chain and a potential integrator, is introduced and suggested as the focus of future research initiatives within supply chain measurements.

Abstract

Purpose

To improve robustness of a dairy supply chain (SC) against corruption, the purpose of this paper is to propose a systemic model of a corruption impacted dairy SC, exposing relationships among SC operations, risks and the impact of corruption.

Design/methodology/approach

Cases from the dairy industry in New Zealand (NZ) are used for thematic analysis of interview data collected from participants at senior levels of NZ dairy firms. Based on these and other inputs from literature, a systemic model is built subsequently.

Findings

Mitigating certain risks can significantly alleviate the impact of corruption, an external factor, on supply chain performance (SCP). The causal loop diagram (CLD) developed here brings out the modifying effect of corruption on dairy risks and SCP.

Practical implications

The illustration of the CLD helps business managers better understand the interactions among risk variables and explains the systemic reasons for SC vulnerability.

Originality/value

This is the first paper to construct a holistic system to comprehensively reveal the interactions of supply chain risks (SCRs) and the impact of corruption. Also, by utilizing SCR interactions, this study indicates a pathway to mitigate the negative effects of corruption through improving dairy SC robustness.

Abstract

Subject area

The case deals with the Bullwhip phenomena that can be observed in a supply chain.

Study level/applicability

This case is suitable for all levels of students, undergraduate MBA to Executive MBA classes and practitioners. Assignment questions are designed from the perspective of teaching this case to a business student audience. The case is ideally suited for a supply chain management course and can be introduced to demonstrate the bullwhip effect in an operations management course.

Case overview

Set in May 2011, the case presents the discussions in the meeting summoned by Mr Srinivas, the director (technical) of Health Pharma (not the name of a real organization) in response to the huge losses faced by the organization in the last financial year. The discussions point to the inability of the organization to appropriately forecast demand across the different echelons and also absence of information transparency, leading to the loss. The catastrophe indicated the need to adopt an ERP solution, which was earlier overlooked by Health Pharma management.

Expected learning outcomes

These are an introduction to the concepts of the bullwhip effect and the case presents a managerial solution to the supply chain problem demonstrated.

Supplementary materials

Teaching notes are available for facilitating the instructor to present and discuss the case in a classroom setting.
