Practitioners and researchers describe inventory service level with metrics that communicate the likelihood of demand fulfillment without considering the ongoing capabilities of the supplier, for example, in‐stock and fill rate. We develop a method for measuring inventory service level that incorporates such supplier capabilities, namely consistency (the ability of a supplier to fulfill orders repeatedly) and recovery (the ability of a supplier to fulfill orders after a lapse in service). Using data from two retail supply chains, we illustrate our approach. To demonstrate the impact of consistency and recovery on supply chain performance, we model a retailer purchasing from competing suppliers with different levels of consistency and recovery. The model incorporates the retailer's uncertainty about demand and the retailer's uncertainty about its suppliers' service levels. We characterize how the retailer's orders and profitability change with a supplier's delivery performance through numerical experiments calibrated with field data. We find notable differences in market share across suppliers with similar traditional inventory service level metrics but differences in consistency and recovery. Further, we observe that a retailer can increase its profitability by determining orders via consistency and recovery in lieu of common metrics like in‐stock. Given the influence of consistency and recovery on supply chain outcomes, we discuss implications for practice and future research. 相似文献

ABSTRACTThis study aims to explore the typology of hotel crime and how it is related to guests’ fear of crime based on a cause-and-consequence model. A total of 873 TripAdvisor reviews were content-analyzed to develop a typology of hotel crime. High-class hotels experienced more theft, fraud, and burglary while low-class hotels encountered more prostitution and drug-related activities. Hotel guests generated a higher fear of crime when crime occurred inside guest rooms, especially in cases of burglary, theft, or fraud. Reviews mentioning crimes were perceived to be more helpful. Managerial implications and best practices of crime prevention are provided for hotel practitioners. 相似文献

An Infant Feeding Practices Study (IFPS) in 1982 in Kenya, which included a cross-sectional survey of a weighted sample of 980 low and middle income Nairobi mothers who had given birth in the previous 18 months, found that most women breastfeed their infants for long periods, but many introduce alternate feeding, especially infant formula, in the 1st 4 months (86 and 50% of the infants were breastfed at 6 and 15 months respectively, but 50% of the 2 month-olds and 63% of the 4 month-olds were receiving substitutes, mostly formula). This is done largely out of the belief that infant formula is an additional health benefit. A workshop to discuss the findings of the IFPS and other available data, and to make policy recommendations urged the adoption of a policy of protection, support and promotion of breastfeeding. Since breastfeeding is already widely prevalent in Kenya, protection of breastfeeding should receive the 1st priority in policy related to infant feeding. Attention should be directed at at least 2 influences which help undermine breastfeeding: widespread availability and promotion of breast milk substitutes. Support for breastfeeding is viewed as the 2nd policy priority. Situations where support can play a helpful role are, women's paid employment outside the home, hospital practices, maternal morbidity, and difficulties in breastfeeding. Since promotion is the least cost effective of the 3 options, and most Kenyan women are already motivated to breastfeed, this should be the last priority. Promotion includes reeduction of mothers to make them better aware of the benefits of breastfeeding. The workshop recommended the dissemination of appropriate information, consisting of standarized messages based on clearcut guidelines, using mass media techniques. 相似文献

In the past decade the development of renewable energy technology has moved from being a somewhat eccentric idea to a significant practical proposition. Indeed, full-scale commercial systems are now in operation in many parts of the world. for example the USA now has more than 1.5 GW of installed wind power capacity feeding into electricity grids, mainly in wind farms in California. This article presents a strategic analysis of renewable energy R&D in the UK. 相似文献

To succeed, Internet retailers must make a profit on the goods and services they sell. But e-tailers are still searching for strategies that work. To test current practices, we became “phantom shoppers” and bought a randomly chosen set of CDs from a variety of Internet retailers. Our findings suggest that order management and logistics skills are pivotal for selling profitably on the Internet. In this article, we show how Internet retailers can deploy resources creatively to attract the right shoppers, convert these shoppers into buyers, and improve the chances of repeat purchase while maintaining profit margins. 相似文献

Inventory record inaccuracy (IRI) challenges multichannel retailers in fulfilling both brick‐and‐mortar and direct channel demands from their distribution centers. The nature and damaging effects of IRI largely go unnoticed because retailers assume daily IRI remains stable over time within the replenishment cycle. While research shows that a high level of IRI is damaging, in reality the level of IRI can change every day. We posit that daily IRI variation increases the uncertainty in the system to negatively affect inventory and service levels. Our research uses data collected daily from a multichannel retailer to ground a discrete‐event simulation experiment. Going beyond testing just the level of IRI, we evaluate daily IRI variation's impact on operating performance. What we find in our empirical data challenges extant assumptions regarding the characteristics of IRI. In addition, our simulation results reveal that daily IRI variation has a paradoxical effect: it increases inventory levels while also decreasing service levels. Moreover, we also reveal that brick‐and‐mortar and direct channels are impacted differently. Our findings show that assumptions and practices that ignore daily IRI variation need revising. For managers, we demonstrate how periods of multiday counting help assess their daily IRI variation and indicate what the causes may be. 相似文献

After reviewing the nature and extent of the landmine problem in Mozambique, this article applies cost-benefit analysis to landmine clearance in that country. The main benefits of clearance are saved lives, injuries and medical costs and the agricultural output that is not lost if landmines are cleared. A very large negative net present value was estimated, a result explicable by the high costs of clearance, the relatively small number of people killed or injured by landmines and the low value of agricultural productivity per hectare. The article concludes with a discussion of the role of the economist in analysing such issues and suggests some alternative areas in which financial resources would provide a greater positive impact on the welfare of Mozambicans. 相似文献

We use survey data and field research to investigate the effects of employee involvement practices on outcomes for blue-collar workers in the auto-supply industry. We find these practices raise wages by 3–5%. The causal mechanism linking involvement and wages appears to be most consistent with efficiency-wage theories, and least consistent with compensating differences. We find no evidence that employee involvement affects plants' survival or employment growth. 相似文献
