Information sharing and coordination mechanisms for managing uncertainty in supply chains: a simulation study

The study aims to investigate the effectiveness of information sharing and coordination mechanisms in reducing uncertainty. Supply chains are constantly subject to unpredictable events that can adversely influence its ability to achieve performance objectives. This paper primarily aims at managing uncertainties originating from unexpectedly large demand spikes. The supply chain literature is full of effective supply chain uncertainty management practices. This paper reviews the different practices for improving management of uncertainty and proposes several combinations of information sharing and coordination mechanism for reducing the uncertainty in supply chains. Next, the proposed combinations are tested on the make-to-stock supply chain of a paper tissue manufacturer using an agent-based simulation approach to show how the use of different levels of information sharing and coordination can be effective in managing uncertainty under daily operations facing a huge mismatch of actual and forecast demand. The findings of this research suggest that, a centralised information structure without widespread distribution of information and coordination is not effective in managing uncertainty of supply chain networks, even with increased frequency of information flow. Similarly, coordinating material flows without widespread information sharing does not improve supply chain uncertainty management. Central coordination of material flows with supply chain wide information sharing across different members is found to be essential in managing supply chains effectively under uncertainty.     

Forecasting errors and the value of information sharing in a supply chain

The paper investigates the impact of forecasting errors and information sharing on the performance of a supply chain. It also examines the impact of forecasting errors on the value of information sharing between retailers and a supplier. Analyses of the simulation outputs show that while information sharing can bring tremendous benefits to the supplier and the entire supply chain, it hurts the retailers under most conditions. Demand pattern and forecasting error distributions faced by the retailers significantly influence the magnitudes of the cost savings as a result of information sharing. The expected bias in forecast errors has a much more significant impact on supply chain performance and the value of information sharing than the standard deviation of forecasting errors and its pattern of deterioration over time. A slight positive bias in the retailer's forecast can actually increase the benefit of sharing information for the supplier and the entire supply chain. However, it can also increase the cost for retailers. The demand pattern faced by retailers also significantly influences the impact of forecasting accuracy on the value of the information sharing. These findings will motivate companies to share information, and will help to design incentive schemes to encourage information-sharing and justify investment in information-sharing projects. The findings can also be used to minimize the negative impact of forecasting errors on supply chain performance.     

How SMEs can benefit from supply chain partnerships

In recent literature on supply chain partnerships in small and medium-sized enterprises (SMEs), there is controversy regarding the benefits of these partnerships. To resolve this controversy, specific information is needed on the implementation of these partnerships by SMEs; an area, that, thus far, has received little academic attention. In this paper, we examine different business functions (production, marketing and sales, purchasing and logistics, research and development (R&D) and finance) within a supply chain partnership. We collected data for each individual function from 279 high-tech SMEs and examined the relationship between the specific types of partnerships and the overall performance of the SMEs. The results indicate that it is only in the area of R&D that partnerships have a significant positive effect on overall firm performance. The results imply that SMEs primarily can benefit from particular types of supply chain partnerships, i.e. R&D partnerships. The results contribute to the debate in the literature by explaining why many SMEs were found not to benefit from these partnerships. We also provide implications for firms and how SMEs can better utilise supply chain management (SCM).     

考虑水平竞争的农产品供应链结构设计

运用博弈论方法，建立了由农户、合作社、社会企业组成的三级农产品供应链，分析合作社和社会企业之间不同水平竞争程度对供应链的影响，以及合作社的益贫性。研究发现：合作社、社会企业之间的不同水平竞争程度，对供应链中所有成员的最优决策和各级成员的总利润均有影响；水平竞争更能体现合作社的益贫性。此外，还分析了合作社独占和共享供货农户对供应链的影响，发现合作社独占供货农户会抑制合作社之间的水平竞争。由此设计出对农户最有利的农产品供应链。     

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.     

Information system utilization in supply chain integration efforts

This paper investigates a set of advisable strategies for information systems utilization in supply chain integration initiatives. Through an analysis of structural relationships among the ways in which information systems are utilized for supply chain integration--i.e. Infrastructural Support, Value Creation Management, Logistical Operations--and supply chain management performance, we argue that there might be a recommended sequence in using information systems for supply chain integration. Tests of hypotheses relating to information systems utilization using empirical data from manufacturing firms indicate that, as the stage of integration moves from independent operation to internal and on to external integration, the focus of information systems utilization should shift from infrastructural support to value creation management and logistical operations, and this change of IS utilization focus can lead to sustainable competitiveness.     

Information sharing in capacity constrained supply chains under lost sales

We present a modelling approach for quantifying the value of information in supply chains using Markov decision processes (MDP). The case where information sharing occurs is modelled using a completely observable MDP. A restricted observation MDP is used to model the case where no information sharing occurs. We illustrate the use of this framework on a two-stage capacity-constrained supply chain consisting of a supplier and a retailer. We quantify the value of information sharing in this setting and construct several performance measures to identify the benefits to both the retailer and supplier as a result of the information sharing partnership.     

Distributed supply‐chain project rescheduling: Part I—impacts of information‐sharing strategies

A supply‐chain project normally involves a number of independent and autonomous enterprises that share information to varying levels. The initial project schedule (preschedule) established at the time of forming the supply‐chain often requires a series of amendments due to unexpected or abrupt disturbances such as temporary resource outage (e.g. machine break), arrival or cancellation of orders from customers, and change in an operation's processing time (e.g. rework). Rescheduling or adaptive scheduling is a process of updating/repairing the preschedule to adapt to the disturbances. Appropriate rescheduling methods must be chosen and applied depending on the specific protocol of sharing information agreed between the enterprises in the supply chain. This paper is concerned with the impacts of different levels of information sharing on the performance of supply‐chain project rescheduling problems. Three rescheduling methods are examined in the research. They are distributed AOR (Affected Operations Rescheduling), negotiation‐based rescheduling (NEG), and centralized total rescheduling (TR). These three rescheduling algorithms represent three typical information‐sharing scenarios: little information sharing, limited information sharing and complete information sharing, respectively. A comprehensive computational study is conducted under different experimental settings. The results show that NEG and distAOR outperforms the TR rescheduling in terms of total cost minimization and stability of schedule and contractual relationship. NEG is superior in both rescheduling efficiency and effectiveness due to the effect of a moderate level of information sharing.
