Using supply chain management to leverage a firm's market orientation

Building supplier relationships and becoming more market oriented have similar building blocks and have similar effects. Strong supplier relationships tend to impact the firm's performance, in part, because the firm can respond to customer needs in a more timely fashion. Supplier relationships tend to be stronger in firms where there is cross-functional sharing of supplier and customer information. Market orientation is an organizational culture that focuses the company on generating market information, cross-functionally sharing that market information, and rapidly responding to that market information to positively impact the performance of the firm. This study explored whether the positive effects of strong supplier relationships are enhanced in market-oriented firms. Results support the notion that supplier relationships are one way of leveraging a firm's market orientation through improved customer responsiveness. Cross-functional sharing of information appears to be the link that ties market orientation and stronger supplier relationships together.     

A firm's capability to calibrate supply chain knowledge—Antecedents and consequences

This paper proposes a conceptual model for a firm's capability to calibrate supply chain knowledge (CCK). Knowledge calibration is achieved when there is a match between managers’ ex ante confidence in the accuracy of held knowledge and the ex post accuracy of that knowledge. Knowledge calibration is closely related to knowledge utility or willingness to use the available ex ante knowledge: a manager uses the ex ante knowledge if he/she is confident in the accuracy of that knowledge, and does not use it or uses it with reservation, when the confidence is low. Thus, knowledge calibration attained through the firm's CCK enables managers to deal with incomplete and uncertain information and enhances quality of decisions. In the supply chain context, although demand- and supply-related knowledge is available, supply chain inefficiencies, such as the bullwhip effect, remain. These issues may be caused not by a lack of knowledge but by a firm's lack of capability to sense potential disagreement between knowledge accuracy and confidence. Therefore, this paper contributes to the understanding of supply chain knowledge utilization by defining CCK and identifying a set of antecedents and consequences of CCK in the supply chain context.     

Outsourcing, performance, and the role of e-commerce: A dynamic perspective

In a highly competitive global environment, many manufacturers respond by setting up outsourcing relations for components and finished products with lower-cost producers on a contractual OEM (original equipment manufacture) basis. In the last decade, we have witnessed a spectacular growth in outsourcing activities led primarily by U.S. and Japanese companies, although their approaches to outsourcing strategy and supplier relations are different. However, outsourcing strategy is not without drawbacks. We offer a dynamic perspective of outsourcing strategy and its performance implications, in which we argue that there is an optimal degree of outsourcing. The outsourcing-performance relationship takes on an inverted-U shape, implying that as firms deviate further from their optimal degree of outsourcing, by either insourcing or outsourcing too much, their performance will suffer disproportionately. We then discuss how e-commerce affects where the optimal point of any particular firm is located, hence explicitly linking developments in e-commerce to changing outsourcing levels. We provide implications for the practice and study of outsourcing and e-commerce.     

Capacity decisions and supply price games under flexibility of backward integration

A key issue in supply chain design for manufacturing firms is how to make a trade-off between strategies of vertical integration and outsourcing. A two-echelon supply chain model with one supplier and one manufacturer is set up to study this issue. The manufacturer makes decisions on two types of capacities, one is core capacity that cannot be outsourced, the other is non-core capacity on which the manufacturer implements a strategy that includes three options—complete, partial or no outsourcing. Such a strategy is referred to as “flexibility of backward integration”. Optimal capacity decisions of the manufacturer are given and the supplier's pricing strategies are discussed. Managerial implications of partial outsourcing are investigated. The impact of the flexibility of backward integration is presented and finally, supply chain coordination is analyzed.     

Retailer policy, uncertainty reduction, and supply chain performance

We investigate how the retailer’s inventory policy affects the total cost of a serial supply chain. When the retailer uses the locally optimal (s,S) policy, there is randomness in order time and order quantity to the supplier whereas the supplier sees randomness only in order quantity for the suboptimal (R,T) policy and only in order time for another suboptimal (Q,r) policy. Using an extensive computational study, we find that the suboptimal policies perform better from the total supply chain perspective. The benefit of policy changes is magnified when the retailer costs are low, when the supplier costs are high, and when there is information sharing.     

The joint replenishment and freight consolidation of a warehouse in a supply chain

We have developed joint replenishment and consolidated freight delivery policies for a third party warehouse that handles multiple items, which have deterministic demand rates in a supply chain. Two policies are proposed and mathematical models are developed to obtain the optimal parameters for the proposed policies. Four efficient algorithms are presented to solve the mathematical models for the two policies. The performances of the two policies with the parameters obtained from the proposed algorithms are then compared with the common cycle approach for 1600 randomly generated problems. The results show the robust performance of the proposed algorithm for both policies.     

The analysis of bullwhip effect in a HMMS-type supply chain

The aim of the paper is to investigate the well-known bullwhip effect of supply chains. Control theoretic analysis of bullwhip effect is extensively analyzed in the literature with the Laplace transform. This paper tries to examine the effect for an extended Holt-Modigliani-Muth-Simon model. A two-stage supply chain (supplier-manufacturer) is studied with quadratic costs functional. It is assumed that both firms minimize the relevant costs. The order of the manufacturer is delayed with a known constant. Two cases are examined: supplier and manufacturer minimize the relevant costs decentralized, and a centralized decision rule. The question is answered, how to decrease the bullwhip effect.     

Benefits of using hybrid business models within a supply chain

Today's competition between supply chains (SC) requires optimized strategies in order to satisfy customers’ demands. The business models used by the SC members play a big role in this delivery of value to the customer. From here the notion that a mismatch between the intended market and the business model used to address it translates into a poor SC performance. As real-life business environments have become really complex, SC members have been forced to use hybrid business models (that is, the integration of features of two different business models). A review of the literature in the area of supply chain management shows that past research have not paid much attention to this issue. The objective of this paper is to quantitatively evaluate the influence these hybrid business models have on the SC performance. For this purpose, a system dynamics (SD) simulation model is developed and tested under different operational conditions, so conclusions can be derived regarding the benefits of the use of hybrid business models.

Influence of the standardization of a firm's productive process on the long-term orientation of its supply relationships: An empirical study

Firms able to manage their supply relationships adequately, which is seen as a first step to success, will be able to exploit important competitive advantages. Many works have previously analyzed these supply relationships in very different contexts and considered the influence of various factors. The influence of the standardization of the productive process on the temporal orientation of interfirm relationships has been analyzed in some depth with respect to sales activities, but rather less in the relationships that standardized firms establish with their suppliers.In an attempt to fill this gap in the literature, the current work analyzes the possible influence of the standardization of the firm's productive process on the long-term orientation of firm-supplier relationships. Specifically, we use a sample of Spanish firms to analyze the moderating effect of this variable on this temporal orientation. Dividing the total sample into two subsamples - “standardized firms” versus “non-standardized firms” - we obtain interesting results and implications about the effects of trust, communication, cooperation, satisfaction and commitment on the long-term orientation of these relationships.     

Optimization of a vendor managed inventory supply chain with guaranteed stability and robustness

In this work we address the steady state optimization of a supply chain model that belongs to the class of vendor managed inventory, automatic pipeline, inventory and order based production control systems (VMI-APIOBPCS). The supply chain is optimized with the so-called normal vector method, which has specifically been developed for the economic optimization of uncertain dynamical systems with constraints on dynamics. We demonstrate that the normal vector method provides robust optimal points of operation for a number of scenarios. Since the method strictly distinguishes economic optimality, which is treated as the optimization objective, from dynamical requirements, which are incorporate by appropriate constraints, it provides a measure for the cost of stability and robustness as a desired side-effect.     

Mutual impacts of product standardization and supply chain design

This paper deals with two major issues for industries; the product design and the supply chain design. These problems are usually solved separately, but in recent years, approaches were proposed to tackle these two problems together. In this paper, we investigate more precisely the links between the standardization of products or components, and the design of the supply chain. First, we show on a little example that there is a great interest to consider simultaneously these two decisions, and that solving these interdependent problems separately could result in a suboptimal, or even a bad, decision. Then, on a simplified problem issued from an industrial case study, we outline the impact of standardization choices on the structure of the supply chain and the gain that can be obtained from solving the problem as a unique compound optimization model. To illustrate the solutions of the problem, we propose graphics in order to visualize, in function of quantities and/or transportation costs, the best decision for the product standardization and for the supply chain design. Graphics also permit to anticipate the impacts of a variation of either quantities or transportation costs, from a specific situation. Such graphics they could be used in a decision aid tool to help companies in their choices. Finally, we show that costs and supply chain structure are highly impacted.     

The intersection of strategic management and supply chain management

Strategic management and supply chain management (SCM) have overlapping interests, yet there has been little exchange between them. We examine areas of overlap and suggest how insights from each field can complement and support the other. Specifically, several of strategic management's theories and its emphasis on explaining firm profits should be useful to SCM. SCM offers to strategic management a new level of analysis and possibly a new type of organization. Overall, we argue that increased interaction between these important areas will benefit knowledge development in both and thereby enhance organizations' ability to meet their goals.     

Towards a sustainable fashion retail supply chain in Europe: Organisation and performance

Sustainability issues are particularly sensitive to the fashion supply chain, given current fierce competition, intensive resource use, and the exposure of penurious labour conditions in some regions.In this paper, we discuss how the sustainability movement is impacting the fashion retail supply chain organisation and its performance. We carried out a study with stakeholders of the fashion industry and we report on their views. We elaborate on the challenges and conflicts of the different dimensions of sustainability, and we discuss how to leverage both the internal and external organisations in the European supply chain.     

Competitive pricing decisions in a two-echelon supply chain with horizontal and vertical competition

This study investigates the pricing decisions in a non-cooperative supply chain that consists of two retailers and one common supplier. The retailers order from the common supplier and compete in the same market. We analyze six power structures that characterize exclusively horizontal competition between the retailers and vertical competition between the supplier and the retailers, leading to different sequences of moves among the chain members. We derive the analytical forms of the equilibrium quantities under each power structure and explore the effect of retail substitutability on the equilibrium quantities among all power structures. We further investigate the performances of the game models as compared with the integrated model.     

The role of ERP tools in supply chain information sharing,cooperation, and cost optimization

The transaction based integrated Enterprise Resource Planning (ERP) software provides different tools that can support supply chain integration but at the same time it has several features that obstructs the integration with business partners. We concentrate on the inventory management aspects of supply chain coordination reviewing the recent quantitative modeling and organizational results available in literature. We summarize the results of a detailed numerical and sensitivity analysis based on our previously published models for supply chain cooperation and joint optimal ordering and shipment policies for the buyer and supplier. These results can be used in enterprise software to measure the potential monetary value of policy coordination, to promote cooperation, and minimize the total supply chain system cost. Our further goal is to combine quantitative tools with organizational and management factors, and to integrate them in a multi-level framework of policy coordination.     

Inventory control in a two-echelon dual-channel supply chain with setup of production and delivery

This paper considers a two-echelon dual-channel supply chain model with setup of production and delivery and develops a new inventory control policy for the supply chain. Previously, a two-echelon supply chain model without setup of production and delivery is considered and a one-for-one inventory control policy is applied to the supply chain. In the inventory control policy, production is stopped when the warehouse inventory reaches the upper limit and is started again immediately after the inventory drops below the limit. Moreover, delivery to the retailer is stopped when the store inventory reaches the upper limit and is started again immediately after the inventory drops below the limit. The total cost that consists of inventory holding costs and lost sales cost is considered, and setup costs are not considered in the total cost. Once setup costs are introduced, the one-for-one inventory control policy is no longer appropriate. Then, this paper develops a new control policy for the two-echelon dual-channel supply chain with setup of production and delivery. As performance measure, the total cost that consists of inventory holding costs, lost sales cost, and production and delivery setup costs is considered, and the total cost calculated on the basis of Markov analysis demonstrates the effectiveness of the proposed control policy.     

Production planning of a hybrid manufacturing-remanufacturing system under uncertainty within a closed-loop supply chain

This paper deals with the production planning and control of a single product involving combined manufacturing and remanufacturing operations within a closed-loop reverse logistics network with machines subject to random failures and repairs. While consumers traditionally dispose of products at the end of their life cycle, recovery of the used products may be economically more attractive than disposal, while remanufacturing of the products also pursues sustainable development goals. Three types of inventories are involved in this network. The manufactured and remanufactured items are stored in the first and second inventories. The returned products are collected in the third inventory and then remanufactured or disposed of. The objective of this research is to propose a manufacturing/remanufacturing policy that would minimize the sum of the holding and backlog costs for manufacturing and remanufacturing products. The decision variables are the production rates of the manufacturing and the remanufacturing machines. The optimality conditions are developed using the optimal control theory based on stochastic dynamic programming. A computational algorithm, based on numerical methods, is used for solving the optimal control problem. Finally, a numerical example and a sensitivity analysis are presented to illustrate the usefulness of the proposed approach. The structure of the optimal control policy is discussed depending on the value of costs and parameters and extensions to more complex reverse logistics networks are discussed.     

Ordering and pricing policies in a manufacturing and distribution supply chain for fashion products

In the paper, we develop a model of manufacturing and distribution supply chains that are operating to meet price-sensitive random demand for products with short life cycles such as fashion products. Two specific scenarios are considered. The manufacturer-controlled scenario is one where the distributor shares price-sensitive random demand with the manufacturer, and the manufacturer controls the supply chain stocking decisions and bears the risk of overstocking costs. The distributor-controlled scenario works in the opposite direction. Prevailing wisdom suggests that the manufacturer should control supply chain decisions (e.g., via vendor-managed inventory). Our results indicate that such an arrangement is against the interest of a distributor selling short life-cycle products. Furthermore, we find that the total supply chain profit is generally higher when the distributor controls the supply chain stocking decisions and bears the risk of overstocking costs.     

The impact of trust on innovativeness and supply chain performance

Trust is identified as a significant predictor of positive performance in business relationships. On the premise that the effects of trust have not been given the deserved scholarly attention in the supply chain context, this paper investigates the effects of trust on innovativeness and supply chain performance. The hypothesised model is operationalised with survey data and analysed using structural equation modelling. The findings add credence to the positive effects of trust and identify trust and innovativeness as antecedents to higher performance in the supply chain.
