In such a scenario, a close relationship between customers and suppliers has enhanced the possibility of technological improvement and innovation. The suppliers are expected to deliver products and services at much faster phase by using direct communication and reliable services. Now, implementation of better marketing strategies plays an important role in increasing sales, profitability and consumer’s satisfaction. Understanding the weaknesses at each level of supply chain helps in not only reducing the cost component leading to profitability but better customer service also. This study aims to analyze the consumer perception towards the strategies which are responsible for influencing the perceptions of unorganized retailers with respect to consumer durables. A sample of 300 retailers from different locations in National Capital Region of Delhi has been selected and studied with reference to various strategies. Factor analysis technique has been applied for the analysis of perceptions of the sample retailers. The results of factor analysis show that product strategies are the most important factor followed by price, place/supply and promotion strategies. The study also focused on whether the importance given to different factors vary across location of retailers. The t- test has been employed to analyze the data. The study reveals that there is no difference between the strategies of the retailers and location but found a little difference in place and supply strategies.","PeriodicalId":129698,"journal":{"name":"Supply Chain Management eJournal","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115891775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The disruption risk is continuously monitored via collaborative forecasting based on advance supply signals—such as financial health and operational viability. We first develop a Markov model to capture the nonstationary, volatile, and dynamic nature of the forecast evolution. We then integrate the forecast into a dynamic programming for inventory hedging under three hierarchies. We derive an easy-to-implement coordination contract and a simple policy structure that facilitates ex ante strategic planning and ex post dynamic execution. The optimal strategy is driven by properly balanced adaptiveness, resilience and intertemporal imperatives. It outperforms the conventional inventory hedging and lean management by reducing premature inventory holding in good times, and timely ramping up safety stock ahead of looming disruptions. The proposed subsidy contract can effectively address double marginalization and information concealment problems via risk sharing, power preserving, and Pareto improving. We show that dynamic forecast is valuable for high margin products, moderate fixed cost, and low demand volatility. Without coordination, mandating supply information sharing can exacerbate supply disruptions. The three instruments are strategic complements and most effective when deployed jointly. This research highlights the importance of integrating forecast, inventory, and contract instruments in managing supply risk dynamically. It also explains two rationales—the resilience and information imperatives—behind recent trends of onshoring and vertical integration.","PeriodicalId":129698,"journal":{"name":"Supply Chain Management eJournal","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130363995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of research reported in this paper is the identification of important strategic changes in the field and to outline future requirements and research opportunities in SCRM.Design/methodology/approach - The Systematic Literature Review (SLR) methodology employed by our research was used to evaluate and categorise a literature survey of quality articles published over a period of 10 years (2000-2010). Additionally, the findings from the SLR have been strengthened through cross validation against results obtained from an associated text mining activity.Findings - The SLR methodology has provided a rich, unbiased and holistic picture of the advances in the field of SCRM. Consequently, important new research areas have been identified based on a multi-perspective descriptive and thematic data analysis. In addition, our analysis based on evolved typologies indicates a growth of SCRM from a nascent to a fairly established activity over the past decadePractical implications - The systematic approach undertaken for the literature review will provide future researchers and managers with an insightful understanding of the scope of the SCRM field. Also, the literature review provides important clues on new research directions for SCRM through identification of gaps in current knowledge.Originality/value - The holistic approach to SCRM was found to be an important missing link in earlier literature surveys. The outcome of the Systematic Literature Review reported in this paper has provided critical insights into the present and future scope of the SCRM field. The identified research insights, gaps and future directions will encourage new research techniques with a view to managing the risks in the globalized supply chain environment.","PeriodicalId":129698,"journal":{"name":"Supply Chain Management eJournal","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127782160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous research shows that the optimal policies in models with random yields even in models with a single installation lack the familiar order-up-to structure and are not myopic. Thus, dynamic programming algorithms are needed to compute optimal policies, and one encounters the “curse of dimensionality”; this is exacerbated here by the need to expand the size and dimension of the state space to accommodate the autoregressive demand feature. Nevertheless, although our model is more complex, we prove that there is an optimal policy with the order-up-to feature and, more importantly, that the optimal policy is myopic. This avoids the computational burden of dynamic programming. Our results depend on two assumptions concerning the stochastic yield, namely that the expected yield at a work station is proportional to the lot size, and the distribution of the deviation of the yield from its mean does not depend on the lot size. We introduce the concept of echelon-like variables, a generalization of Clark and Scarf's classical concept of echelon variables, to derive the structure of optimal policies. Furthermore, we show that the same kind of policy is optimal for several criteria: infinite-horizon discounted cost, infinite-horizon long-run average cost, and finite-horizon discounted cost with the appropriate choice of the salvage value function.","PeriodicalId":129698,"journal":{"name":"Supply Chain Management eJournal","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127205982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The integrated framework incorporates two main views on managing disruptions, namely pre- and post-disruption views, which are usually treated as separate issues in existing frameworks described in literature. The proposed integrated framework is used to structure literature review on the supply chain risk and disruption management. The literature review gives an overview of key aspects and specific methods which can be used for each step in the framework. Finally, two main observations in the existing literature on supply chain risk/disruption management are discussed. The first observation is that the literature has not uniformly discussed different parts of the framework. In general, the post-disruption process for managing supply chain disruptions has received relatively less attention than pre-disruption activities. The second observation which can be regarded as a direction for future research is lack of quantitative studies involving modeling and simulation to support the decision makers in better handling supply chain disruption.","PeriodicalId":129698,"journal":{"name":"Supply Chain Management eJournal","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129158143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The outcome of information acquisition may turn out to be successful such that the firm learns much about the market demand, thus becoming “informed,” or unsuccessful such that it learns very little about the market demand, thus remaining “uninformed.” After the outcome becomes clear, the firm knows its information status, informed or uninformed, and the information content if informed. The client firm usually requires strict confidentiality that forbids the consultant to make any disclosure about the information acquisition, believing that greater informational advantage will surely be to its own benefits. As a result, neither the information content nor the information status is known to any third party. But should the firm always care so much about strict confidentiality? Will it be beneficial if the firm's information status, but not the information content, is known to its partners or any other firms? We investigate this issue in the context of a two-tier supply chain. A manufacturer offers a menu of contracts for supplying a product to a retailer who sells it in a market with random demand that has a known continuous distribution. The retailer hires a consultant to acquire demand information, with uncertain outcome. With probability t , the retailer becomes informed about the market demand, and with probability 1 − t , he remains uninformed, where the probability t can be regarded as representing the retailer's information acquisition capability. We find that disclosing its information status benefits the retailer if its information acquisition capability is less than stellar and the market variability is intermediate. Our investigation shows that there are benefits that are foregone by following strict confidentiality but can potentially be recovered by switching to a policy of partial confidentiality.","PeriodicalId":129698,"journal":{"name":"Supply Chain Management eJournal","volume":"391 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131440614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
