A centralized/decentralized design of a full return contract for a risk-free manufacturer and a risk-neutral retailer under partial information sharing: A discussion

This paper discusses some aspects of the centralised version of the supply chain coordination method that uses the so-called Alternating Direction Method (ADM) presented by Jeong (2012, A centralized/decentralized design of a full return contract for a risk-free manufacturer and a risk-neutral retailer under partial information sharing. International Journal of Production Economics 136 (1), 110–115). We show that the method requires both from the retailer and the manufacturer to faithfully follow the proposed algorithm, without any attempt to follow their own interests in gaining higher profits. We also warn that the condition of the information privacy is violated also in partial information sharing model. Furthermore, we correct an error in one of the equations.     

A serial supply chain of newsvendor problem with safety stocks under complete and partial information sharing

We consider a supply chain where multiple members are serially connected. The decision is to determine the ordering quantity of a member to the next upstream member in the supply chain. The basic cost model is similar to the newsvendor problem with additional consideration to safety stock. This paper presents optimal approaches for coordination of the supply chain under both complete and partial information sharing in order to maximize the total expected benefit. For complete information sharing we develop an optimal coordination algorithm. For partial information sharing, we propose an optimal coordination algorithm based on the Alternating Direction Method and the Diagonal Quadratic Approximation Method. A numerical example is discussed to show the optimal convergence of ordering quantities and discuss the properties of the proposed algorithms.     

Trade promotion mode choice and information sharing in fashion retail supply chains

Trade promotion has a significant impact on the retail business, particularly in the fashion sectors. Manufacturers have traditionally been concerned with the inefficiency of trade promotion due to the low pass-through rate of the trade deals from retailers to customers. The scan-back (SB) trade deal, which monitors a retailer's sales via an IT system, benefits the manufacturer, but may or may not benefit the retailer. We provide insight into when a retailer in a two-stage supply chain has incentive to accept the SB trade deal. We show that (1) the manufacturer and the entire supply chain can always benefit from the SB trade deal while the retailer benefits only under some conditions, and that (2) both the retailer and the manufacturer can benefit from the SB trade deal if the SB deal is accompanied by a buyback (BB) contract. We examine the effect of a retailer's confidential pass-through rate on both the retailer's and the manufacturer's incentives to use the SB trade deal.     

Coordinating a channel with asymmetric cost information and the manufacturer's optimality

In a manufacturer-retailer system with private retail cost information, we find that a set of incentive-compatible contracts consisting of wholesale and buyback prices can coordinate the channel for any retail cost. We then design two wholesale-buyback contracts by imposing a cutoff point on the retail cost. The first contract maximizes the manufacturer's expected profit while ensuring the channel is coordinated. The second contract assumes the same contractual structure without considering the effect on the channel. Both contracts are exactly solved. We find from numerical study that the manufacturer in the first contract can perform closely to the second one in many cases, and cases exist where both the manufacturer and the channel can do better in the first contract versus the second one.     

Supply chain integration and performance: The effects of long-term relationships, information technology and sharing, and logistics integration

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 integrations of both information and material flows between supply chain partners and their effect on operational performance. Specifically, we examine the role of long-term supplier relationship as the driver of the integration. Using data from 232 Australian firms, we find that logistics integration has a significant effect on operations performance. Information technology capabilities and information sharing both have significant effects on logistics integration. Furthermore, long-term supplier relationships have both direct and indirect significant effects on performance; the indirect effect via the effect on information integration and logistics integration.     

The impact of information technology on supply chain capabilities and firm performance: A resource-based view

Organizations increasingly rely on information technology (IT) to improve the supply chain process. Yet, past evidence suggests that the investment in IT per se does not guarantee enhanced organizational performance. Drawing from the resource-based view, this study proposes that IT-enabled supply chain capabilities are firm-specific, and hard-to-copy across organizations. These capabilities can serve as a catalyst in transforming IT-related resources into higher value for a firm. Based on data collected from surveying supply chain and logistics managers in various industries, the present study sheds light on these issues. The findings provide a new perspective in evaluating IT investment in the supply chain process.     

A causal analysis of the impact of information systems and supply chain management practices on operational performance: Evidence from manufacturing SMEs in Turkey

This study has empirically tested a framework identifying the causal links among supply chain management (SCM) and information systems (IS) practices, SCM–IS related inhibiting factors and operational performance based on a sample of 203 manufacturing SMEs operating in the manufacture of fabricated metal products and general purpose machinery within the greater metropolitan area of Istanbul in Turkey. Moderating effect of SCM and IS related enabling factors on the above mentioned relationships is also investigated in this study. Tests of hypotheses indicate that both SCM and IS practices positively and significantly influence the operational performance of sample firms. The results of the structural model also indicate a strong support for negative relationships between SCM–IS related inhibitors and the implementation levels of both SCM and IS practices. Similarly, a strong support was found for the hypothesized negative relationship between SCM–IS inhibitors and operational performance of SMEs. Finally, we verified the moderating impact of SCM–IS enablers on the link between SCM practices and operational performance. A similar moderating impact was also found with regard to the relationship between IS practices and operational performance.     

A strategic-tactical model for the supply chain design in the delocalization context: Mathematical formulation and a case study

In this paper, we propose a mathematical model for the design of supply chains in the delocalization context. Our main objective is to develop a strategic-tactical supply chain design model that integrates all the relevant components that characterize the delocalization problem. We adopt the activity based approach to model the problem and we focus on the logistic decisions of activity location, technology choice, supplier selection, etc., and the financial decisions of transfer pricing, transportation costs allocation, etc. The mathematical formulation is illustrated by a case study from the automotive sector. A comparison between the model solution and the real decisions is used to prove the applicability and the utility of the proposed model.
