Implementing coordination contracts in a manufacturer Stackelberg dual-channel supply chain

We examine a manufacturer's pricing strategies in a dual-channel supply chain, in which the manufacturer is a Stackelberg leader and the retailer is a follower. We show the conditions under which the manufacturer and the retailer both prefer a dual-channel supply chain. We examine the coordination schemes for a dual-channel supply chain and find that a manufacturer's contract with a wholesale price and a price for the direct channel can coordinate the dual-channel supply channel, benefiting the retailer but not the manufacturer. We illustrate how such a contract with a complementary agreement, such as a two-part tariff or a profit-sharing agreement, can coordinate the dual-channel supply chain and enable both the manufacturer and the retailer to be a win-win.     

Supplier integration and company performance: A configurational view

Supplier integration is considered a key managerial strategy for improving buyer performance. This study adopts a configurational approach to supplier integration, based on the interaction and complementarity between supply chain management practices. In this perspective, this study explores the impact of supplier integration and measures aimed at creating a fast supply network structure on buyer performance. This research also attempts to ascertain whether these practices can exert a synergic effect. After examining data from a sample of 186 manufacturing plants, we can conclude that while taken singly supplier integration and fast supply network structure practices have a markedly positive effect on the performance goals considered (i.e., efficiency, schedule attainment and flexibility); in addition, they interact to produce an additional synergic effect on efficiency and schedule attainment. The analyses also reveal that investing in FSNS or SI initiatives alone can be risky. On one hand, when companies fail to make any effort to structure their supply network in order to achieve fast lead times, the impact of supplier integration on efficiency and schedule attainment may be hindered and, in extreme cases, supplier integration might even have no impact at all. On the other hand, investing only in fast supply network structure initiatives, without striving to achieve an adequate level of supplier integration might well be useless: indeed, even detrimental to any improvement in performance. These findings provide useful guidelines for managers who must decide how to combine supplier integration and fast supply network structure initiatives in order to improve or maximize performance.     

A framework for managing sustainable palm oil supply chain operations: a case of Indonesia

The challenges faced by the palm oil industry in Indonesia lie in the supply chain risk management, specifically in the integration of decision-making at the operational level. Problems at this level have become more apparent while the industry continues to face pressures as a consequence of the strict conditions imposed by, predominantly, international trading communities, and in some cases, by the environmental issues from domestic and overseas. As part of an effort to address the underlying problems, this paper aims to propose a conceptual framework that can be used to effectively manage the palm oil supply chain, by integrating risk assessment, performance measurement and supply chain optimisation, which will be compiled into a decision-making tool. The perceived benefits from the implementation of this framework include more realistic target planning, clearer prediction of risks and better visibility of the operating performance.     

Eco-efficient supply chain networks: development of a design framework and application to a real case study

This paper presents a supply chain network design framework that is based on multi-objective mathematical programming and that can identify ‘eco-efficient’ configuration alternatives that are both efficient and ecologically sound. This work is original in that it encompasses the environmental impact of both transportation and warehousing activities. We apply the proposed framework to a real-life case study (i.e. Lindt & Sprüngli) for the distribution of chocolate products. The results show that cost-driven network optimisation may lead to beneficial effects for the environment and that a minor increase in distribution costs can be offset by a major improvement in environmental performance. This paper contributes to the body of knowledge on eco-efficient supply chain design and closes the missing link between model-based methods and empirical applied research. It also generates insights into the growing debate on the trade-off between the economic and environmental performance of supply chains, supporting organisations in the eco-efficient configuration of their supply chains.     

Implementation of just-in-time in a small company: A case study

This paper deals with the implementation of JIT in a small company in Taiwan that produces different kinds of automobile lamps such as rear combination lamps and front turn signal lamps. JIT systems have tremendous effects on all operations of a firm, including design, accounting, finance, marketing, distribution, etc., and thus are of interest to all levels of a firm's management. Realizing the success of JIT, large-scale manufacturing companies all over the world have implemented JIT in their production systems with the objective of improving their competitiveness. Nevertheless, small and medium enterprises SMEs play a major role in the national economy. However, JIT has not received serious attention from SMEs. Realising the importance of improving the performance of SMEs, a case study is presented to motivate practitioners to implement JIT in their SMEs. In addition, future research directions in the areas of implementing JIT in SMEs are presented.     

A harmony search-based memetic optimization model for integrated production and transportation scheduling in MTO manufacturing

This paper investigates an integrated production and transportation scheduling problem in an MTO supply chain. A harmony search-based memetic optimization model is developed to handle this problem, in which certain heuristic procedures are proposed to convert the investigated problem into an order assignment problem. A novel improvisation process is also proposed to improve the optimum-seeking performance. The effectiveness of the proposed model is validated by numerical experiments. The experimental results show that (1) the proposed model can solve the investigated problem effectively and that (2) the proposed memetic optimization process exhibits better optimum-seeking performance than genetic algorithm-based and traditional memetic optimization processes.     

Sustainable supply chain network design: A case of the wine industry in Australia

This paper comes at a time when many companies and people are increasingly facing various global problems linked to sustainability challenges, and when the literature is still scarce on research incorporating all three dimensions of sustainability in supply chain analytical models. The paper conducts a case-based modeling study to address this gap in the area of supply chain network design. We investigate the wine supply chain and propose a generic model for sustainable wine supply chain network design encompassing economic, environmental and social objectives. The case company is a real large-sized wine company located in Australia, for which a customized model is provided. Both models are formulated as a multi-objective mixed-integer program and solved using the augmented ϵ-constraint method by CPLEX. Social implications of the feasible scenarios are examined through introducing social impact coefficients. Non-dominated solutions are obtained and some balanced scenarios are proposed. The results show trade-offs between the objectives, yet more interestingly demonstrate how large is the gap between the existing supply chain configuration and the proposed scenarios in terms of supply chain cost and emissions.

Measuring and analysing supply chain schedule stability: A case study in the automotive industry

Final assembly plants send material schedules to first-tier suppliers who in turn send schedules to second-tier suppliers and so on through the multiple tiers of the supply chain. A key cost driver for the supply chain is a schedule characteristic termed stability. The Total Quality Management approach is applied to improve schedule stability in the supply chain of a large vertically integrated automotive manufacturer. A measurement described, actual stability results are provided, the causes of instability are listed, and some corrective actions are specified. Results indicate that schedule stability can be improved without damaging the performance of other measures such as inventory and customer responsiveness. and analysis process is     

The green company: A case of labor management and employee empowerment in a small business

The basis of this teaching case is a small nursery and landscape business in the Northeast United States. The case describes how the company attempted to implement a decentralization and employee empowerment program to move relevant decision-making closer to the work site. It illustrates that shifting from a centralized top-down style of management to a decentralized incentive driven style can create many challenges for a small business. Moreover, top management should be cautious about delegating responsibilities to line managers. Not all employees will be successful in this new environment, and without procedures for monitoring and control, significant learning may be necessary as employees move into this environment.     

Scrutinising the interplay between governance and resilience in supply chain management: A systems thinking framework

Supply chain disruptions recurrently challenge end-to-end operations owing to the ambiguous understanding of the role of governance in impacting supply network resilience. This paper scrutinises the relevant literature to understand the plethora of interpretations in supply chain governance and resilience while further providing a new perspective on the representation of the interplay between governance and resilience in supply chains. In this regard, the Systems Thinking lens is adopted to pull together the typologies and constructs of supply chain governance and resilience from the literature. Methodologically, System Dynamics modelling principles are leveraged to capture the underpinning structural interdependencies in a causal loop diagram. The study reveals that endogenous and exogenous supply chain governance processes and mechanisms support the intrinsic and extrinsic resilience in networks. Overall, this research contributes to the supply chain risk management domain by synthesising the interplay between governance and resilience, identifying pertinent typologies, and articulating research propositions that can inform decision-making at policy and management levels.     

Knowledge transfer and R&D in pharmaceutical companies: A case study

This paper analyzes the consequences for the knowledge transfer and the organization of R&D of pharmaceutical companies after the acquisition of biotech companies. Based on four in-depth case studies, this paper comes to the conclusion that there is no systematic biotechnological know-how transfer from the biotech to the pharmaceutical company after the acquisition. Instead, the biotech companies remain independent and take over the role of centers of excellence for R&D within the pharmaceutical companies because that is the only way of preserving the innovative capabilities of the biotech company.     

Coordinated Contract Decisions in a Make‐to‐Order Manufacturing Supply Chain: A Stochastic Programming Approach

One of the important objectives of supply chain S&OP (Sales and Operations Planning) is the profitable alignment of customer demand with supply chain capabilities through the coordinated planning of sales, production, distribution, and procurement. In the make‐to‐order manufacturing context considered in this paper, sales plans cover both contract and spot sales, and procurement plans require the selection of supplier contracts. S&OP decisions also involve the allocation of capacity to support sales plans. This article studies the coordinated contract selection and capacity allocation problem, in a three‐tier manufacturing supply chain, with the objective to maximize the manufacturer's profitability. Using a modeling approach based on stochastic programming with recourse, we show how these S&OP decisions can be made taking into account economic, market, supply, and system uncertainties. The research is based on a real business case in the Oriented Strand Board (OSB) industry. The computational results show that the proposed approach provides realistic and robust solutions. For the case considered, the planning method elaborated yields significant performance improvements over the solutions obtained from the mixed integer programming model previously suggested for S&OP.     

Formal governance,interfirm coordination,and performance in partnerships: An empirical investigation of a mediation model

This study investigates the extent to which formal governance mechanisms such as contracts and equity ownership affect interfirm coordination and partnership performance. We analysed data from a survey of 301 Korean firms to show that interfirm coordination partially mediates the relationship between contract completeness, defined as the extent to which a contract specifies task operations and contingencies, and partnership performance. Furthermore, we find that more complete contracts can attenuate the negative effects of equity ownership on coordination, and that this effect is particularly strong when partner tasks are interdependent and relational norms are weak.     

Developing a supplier selection system through integrating fuzzy AHP and fuzzy DEA: a case study on an auto lighting system company in Taiwan

Supplier selection plays a very important role in supply chain management. This study intends to develop a novel performance evaluation method, which integrates both fuzzy analytical hierarchy process (AHP) method and fuzzy data envelopment analysis (DEA) for assisting organisations to make the supplier selection decision. Fuzzy AHP method is first applied to find the indicators’ weights through expert questionnaire survey. Then, these weights are integrated with fuzzy DEA. We use α -cut set and extension principle of fuzzy set theory to simplify the fuzzy DEA as a pair of traditional DEA model. Finally, fuzzy ranking using maximising and minimising set method is able to rank the evaluation samples. A case study on an internationally well-known auto lighting OEM company shows that the proposed method is very suitable for practical applications.     

Revised MRP for reducing inventory level and smoothing order releases: a case in manufacturing industry

Although material requirement planning (MRP) systems are widely used in manufacturing companies, they exhibit significant drawbacks. Rev MRP algorithm has been developed in order to reduce the system nervousness, generate a more regular pattern of order released and lower inventory levels. The aim of this paper is to test the Rev MRP algorithm on the case of one of the largest Italian manufacturing companies of home appliances. The company provided three sets of real data, referring to three different runs of their MRP. Results showed that the Rev MRP outperformed the company’s MRP smoothing the production order releases, eliminating overshoots and drastically reducing the inventory levels along the supply chain, even in case of frequent forecasts updates.     

Sustainable planning strategies in supply chain systems: proposal and applications with a real case study in fashion

Abstract

Pollution generated by the fashion industry drives people to pay attention to fashion companies’ sustainability practice. This increase in attention has induced vast literature studying the related area. Since the fashion apparel supply chain is complicated which involves a lot of interrelated steps and decisions, how fashion companies can identify the demand in sustainable fashion and make the right decision in resource allocation throughout the supply chain becomes a critical issue. As a result, this paper examines how a fashion company can develop a successful sustainable planning strategy throughout the sustainable fashion supply chain. The sustainability attributes and the sustainable planning strategy mechanism are also discussed. Based on the institutional theory and resource-based theory, we first analyse the external pressure and internal motivations for companies to adopt a sustainable planning strategy in the fashion supply chain. We then identify the core stakeholders related to the sustainable planning strategy and propose how the decision-making theory can help develop the sustainable supply chain management mechanism. Next, we establish a sustainable planning strategy framework. Finally, via a case study with public data on the fashion giant brand Nike, we explore the application of our proposed sustainable planning strategy framework. The finding suggests that the strategic planning of fashion companies on sustainability can improve the performance of the stakeholders throughout the whole sustainable fashion supply chain.
