SUPPLY CHAIN INFORMATION SHARING IN A VENDOR MANAGED INVENTORY PARTNERSHIP

Vendor Managed Inventory (VMI) involves the vendor making the replenishment decision for products supplied to a customer based on various inventory and supply chain policies. Information sharing between supply chain members is required in VMI. Sometimes VMI decisions are delayed and/or the information shared is inaccurate. This research examines the effects of information delay and accuracy, and the sharing of sales and forecast information in a VMI environment facing stationary and nonstationary demand. The simulation experiments show the impact of information delay, information inaccuracy, and information sharing on a variety of performance measures, including inventory levels and fill rates.     

VENDOR‐OWNED INVENTORY MANAGEMENT ARRANGEMENTS IN RETAIL: AN AGENCY THEORY PERSPECTIVE

This paper undertakes two related tasks to augment current understanding regarding vendor‐owned inventory management (VOIM) arrangements implemented in the retail industry. The first task formally juxtaposes three prevalent forms of VOIM arrangements (i.e., Consignment, Pay‐On‐Scan, and Scan‐Based Trading) to one another and identifies three dimensions (i.e., Relevant Data Visibility, Timeliness of Information Release, and Shrink Responsibility) that serve to discriminate among them. The second task applies an Agency Theory lens to uncover differing profiles of characteristics underlying the retailer‐vendor relationship across the Consignment, Pay‐On‐Scan, and Scan‐Based Trading arrangements. These conceptual results contribute to and have implications for the science and practice of VOIM arrangements in the retail industry.     

INVENTORY CONSIDERATIONS IN NETWORK DESIGN

Network design is a cornerstone of logistics management. It is traditionally used to determine the number and location of warehouses that optimize the joint transportation and fixed warehousing cost. We propose a network design model that enables managers to include inventory cost simultaneously with transportation and fixed warehouse cost in the optimization process. The proposed model treats inventory cost as a discrete function of the number of warehouses. The research also includes an illustration of the application of the proposed model using data obtained from a national retailer based in the Midwest. Results show that savings can be substantial and that the proposed model might also be used to define different configurations for C items than for A and B items.     

MANAGING VENDOR INVENTORY IN A DUAL LEVEL DISTRIBUTION SYSTEM

Collaborative arrangements among members of the supply chain have received a great deal of interest in recent years as a means of reducing costs. One such arrangement is vendor managed inventory (VMI). VMI allows the vendor to make decisions concerning the quantity and timing of deliveries to the retailer. Such an arrangement offers the potential of a more efficient supply chain by removing the negative effects of retail ordering policies. A thorough review of the literature was conducted to identify factors likely to impact the performance of a VMI partnership. Computer simulation was used to study the effects of these factors from both the vendor's and retailer's perspectives. The results lend insight into the performance of VMI and guidance for managers as to the environments in which VMI is most effective.     

INTERNET RETAILING INTERMEDIATION: A MULTILEVEL ANALYSIS OF INVENTORY LIQUIDITY AND FULFILLMENT GUARANTEES

Internet retailers intermediate online markets by setting prices, matching wholesalers' supply with consumers' demand, affording inventory liquidity, and meeting fulfillment guarantees to consumers. Little attention has been given to studying the two latter intermediation functions. To fill this research gap, this study examined a sample of 25 mainstream online retailers in some 704 transactions with consumers. The study evaluates the inventory liquidity and the fulfillment guarantees these Internet retailers provide to consumers. Furthermore, it presents a path‐analysis model, which suggests that retailers coordinate their actual and promised inventory‐liquidity and delivery performance to satisfy the fulfillment guarantees made to consumers. Moreover, the results show that key transactional attributes (i.e., the net price and the number of items fulfilled) commonly present in Internet markets and visible to all market participants impact both the levels of inventory liquidity and the delivery performance of the transactions between consumers and Internet retailers.     

A CONVENIENT MULTISECTORAL POLICY CONTROL FOR ICT IN THE US ECONOMY

Through the application of the Macro Multiplier (MM) approach on an Input–Output matrix for US economy in year 2005, the paper identifies the ‘convenient’ structure of a policy control on final demand, oriented to a particular policy objective. The approach quantifies a set of aggregated scale effects, called MM, and the associated structures of both policy and objective variables. In this way the policy maker can both get a complete picture of the patterns of the objective that can be attained and determine a ‘convenient’ structure of the policy variable that compels the model towards those patterns.     

A COMPARISON OF THE ECONOMIC ORDER QUANTITY AND QUICK RESPONSE INVENTORY REPLENISHMENT METHODS

When determining order quantity, logistics managers can choose between ordering the Economic Order quantity (EOQ) or a Quick Response (QR) quantity. QR is a general term that collectively describes several rapid‐replenishment inventory methods such as Just‐In‐Time or Continuous Replenishment. The QR order quantity is defined as the minimum inventory needed to support operations until the next delivery. The EOQ and the QR methods are substantially different because the EOQ minimizes the joint cost of ordering and holding inventory whereas the QR method minimizes only the cost of holding inventory. The goals of this research are to compare the costs of the two methods and to propose rules that help managers select the more appropriate method to use in specific situations.     

THE IMPACT OF POINT‐OF‐SALE DATA INACCURACY AND INVENTORY RECORD DATA ERRORS

The presence or absence of error in point‐of‐sale (POS) data and inventory system records directly affects retailer performance. This study identifies various error sources in retail supply chains and studies the influence of inventory and POS (demand) errors in a simulated retail outlet according to fill rate and average inventory. Other things being equal, we find that inventory record error reduces fill rate more than demand error. This study adds further evidence to other studies that suggest the costs caused by errors in POS systems may be overstated.     

THE IMPACT OF CUSTOMER RESPONSE ON INVENTORY AND UTILIZATION POLICIES

Drawing on extensive fieldwork at a semiconductor manufacturer, this research provides a framework for understanding how customer response and long production delays interact, leading to increased demand amplification across a company's supply chain. Investigating the impact resulting from the higher demand amplification, suggestions are derived for the company's capacity utilization and inventory policies     

Is sponsorship retention dependent on the geographic location of the sports facility?

This study tested the hypothesis that 'revenue maximization of the tenants of sports facilities is dependent on the geographical location of the facility (location of distribution)'. Revenue maximization was operationalized pertaining to sponsorship. A survey instrument was sent to all sponsors of a Melbourne-based football club. The sponsors were grouped as location dependent and location independent based on the location of their head office and financial turnover achieved in the area around the sports facility. The survey collected information on three different steps in the sports consumption process including 'coming to the sports facility', 'being in and around the sports facility' and 'being serviced in the sports facility'. t-Tests were run for most items of the questionnaire in relation to location dependency. Indicative evidence was found in support of the general hypothesis. In particular, direct sales (turnover) in the area around a sports facility were found to be an important factor when considering the issue of location dependency. Smaller, lowspending sponsors with an important percentage of turnover in the area around the sports facility were less likely to move with the football club to a (remote) new facility. In relation to sponsors' objectives, it was found that the objectives of location-dependent sponsors are directed more towards direct sales (or product /brand related as defined elsewhere), whereas location-independent sponsor's objectives seemed to be indirectly related to sales (or corporation related and generation of media benefits as defined elsewhere).     

INTERORGANIZATIONAL TIME‐BASED POSTPONEMENT IN THE SUPPLY CHAIN

This paper presents the results of empirical research on the use of time‐based postponement in a supply chain context using data collected from two manufacturers, a distributor, and a retailer. The analysis shows that implementing postponement at the firm level can result in the supply chain carrying more inventory. In order to achieve its full potential, postponement needs to be implemented across organizations in the supply chain.     

AN INVESTIGATION INTO THE EFFECT OF FULL‐SCALE SUPPLY CHAIN MANAGEMENT SOFTWARE ADOPTIONS ON INVENTORY BALANCES AND TURNS

Supply chain management (SCM) software vendors, analysts, and others claim that firms implementing SCM software stand to benefit by being able to reduce inventory holdings and increase inventory turns. We theorize that full‐scale implementations lead to system‐wide inventory optimization, which in turn leads to cost improvement associated with inventory balances and turns. To examine the question, we develop an analytical model of inventory optimization, then analyze the effects of the model with a numerical experiment, and finally confirm the results with an empirical examination. We find that firm‐wide implementation is significant in explaining improvement in inventory metrics, relative to pre‐implementation metrics for our sample. Our empirical tests indicate that implementing SCM software across only a portion of the firm does not impact inventory metrics, but that the scale of implementation does. More precisely, we find that firms implementing SCM software across the entire company significantly improve both inventory turns and inventory as a percent of revenue relative to partially‐implementing firms and non‐implementers.     

CONSUMER DIRECT FULFILLMENT PERFORMANCE IN INTERNET RETAILING: EMERGENCY TRANSSHIPMENTS AND DEMAND DISPERSION

The collaborative fulfillment of consumer orders by Internet retailers and wholesalers has proven important in the realization of sustainable levels of online profitability. Concentrating on consumer direct fulfillment (or drop shipping), an empirical simulation model evaluates avenues for improving logistical performance. The empirical simulation model centers on the online music CD retailing industry. It evaluates the effects of emergency transshipments and demand dispersion on inventory and product‐release performance, as well as on transportation costs, in consumer direct fulfillment operations. Results show that emergency transshipments improve inventory and product‐release performance in these operations. Furthermore, the inventory‐performance improvements are maximized when inventory facilities fulfill demand that is uniformly balanced across markets primarily assigned to each facility. Finally, gains in inventory and release performance obtained from emergency transshipments outweigh additional transportation costs incurred from a greater reliance on emergency transshipments for consumer direct fulfillment.

THE RELATIONSHIP BETWEEN PURCHASING AND SUPPLY MANAGEMENT'S PERCEIVED VALUE AND PARTICIPATION IN STRATEGIC SUPPLIER COST MANAGEMENT ACTIVITIES

As firms have placed more emphasis on their core competencies and outsourced production and services to suppliers, effective cost management of purchases has become a critical factor in achieving corporate success. The Purchasing and Supply Management (PSM) function is generally responsible for obtaining goods and services from outside suppliers. Techniques such as total cost of ownership, supplier cost structure analysis, and target costing have become important tools for PSM to manage inbound supply costs. Results of a survey indicate that the perceptions of PSM by peer functions and top management, in terms of PSM's importance and accountability, are related to implementing the strategic cost management activities of total cost of ownership, supplier cost structure analysis, and target costing.     

THE ROLE OF PURCHASING IN CORPORATE SOCIAL RESPONSIBILITY: A STRUCTURAL EQUATION ANALYSIS

Researchers in the field of corporate social responsibility (CSR) have examined a broad array of activities including environmental management, ethical issues, the advancement of a diverse workplace, safety, human rights, philanthropic donations, and community involvement. Yet despite over 30 years of inquiry in this field, there has been no holistic, empirical investigation of the particular dimensions or sets of activities that are encompassed by CSR and the relationship between ethics and CSR. In the purchasing and supply management literature, similar sets of activities have been investigated, but generally as separate, standalone streams of research with little recognition of their potential inter‐relatedness. The current study empirically identified the dimensions of purchasing's involvement in CSR and applied the label purchasing social responsibility (PSR).     

MEAN‐VARIANCE POLICY FOR DISCRETE‐TIME CONE‐CONSTRAINED MARKETS: TIME CONSISTENCY IN EFFICIENCY AND THE MINIMUM‐VARIANCE SIGNED SUPERMARTINGALE MEASURE

The discrete‐time mean‐variance portfolio selection formulation, which is a representative of general dynamic mean‐risk portfolio selection problems, typically does not satisfy time consistency in efficiency (TCIE), i.e., a truncated precommitted efficient policy may become inefficient for the corresponding truncated problem. In this paper, we analytically investigate the effect of portfolio constraints on the TCIE of convex cone‐constrained markets. More specifically, we derive semi‐analytical expressions for the precommitted efficient mean‐variance policy and the minimum‐variance signed supermartingale measure (VSSM) and examine their relationship. Our analysis shows that the precommitted discrete‐time efficient mean‐variance policy satisfies TCIE if and only if the conditional expectation of the density of the VSSM (with respect to the original probability measure) is nonnegative, or once the conditional expectation becomes negative, it remains at the same negative value until the terminal time. Our finding indicates that the TCIE property depends only on the basic market setting, including portfolio constraints. This motivates us to establish a general procedure for constructing TCIE dynamic portfolio selection problems by introducing suitable portfolio constraints.
