摘要：This research examines how organizations simultaneously manage their operations and occupational health and safety. Although both safety and operations scholars conduct research in the same operational settings, they have reached different, yet untested, conclusions about the relationship between creating a safe workplace and creating a productive workplace. The results from a series of 10 case studies show that it is possible to create safe and productive workplaces, but that many facilities ...

摘要：We address an inventory rationing problem in a lost sales make-to-stock (MTS) production system with batch ordering and multiple demand classes. Each production order contains a single batch of a fixed lot size and the processing time of each batch is random. Assuming that there is at most one order outstanding at any point in time, we first address the case with the general production time distribution. We show that the optimal order policy is characterized by a reorder point and the optimal ...

摘要：When facing supply uncertainty caused by exogenous factors such as adverse weather conditions, firms diversify their supply sources following the wisdom of not holding all eggs in one basket. We study a firm that decides on investment and production levels of two unreliable but substitutable resources. Applying real options thinking, production decisions account for actual supply capabilities, whereas investment decisions are made in advance. To model triangular supply and demand correlations,...

摘要：Quality issues in milk-arising primarily from deliberate adulteration by producers-have been reported in several developing countries. In the milk supply chain, a station buys raw milk from a number of producers, mixes the milk and sells it to a firm (that then sells the processed milk to end consumers). We study a non-cooperative game between a station and a population of producers. Apart from penalties on proven low-quality producers, two types of incentives are analyzed: confessor rewards f...

摘要：We apply service-operations-management concepts to improve the efficiency and equity of voting systems. Recent elections in the United States and elsewhere have been plagued by long lines, excessive waiting times, and perceptions of unfairness. We build models for the waiting lines at voting precincts using both traditional steady-state queueing methods and simulation models. We develop solution methods to allocate voting machines optimally to precincts. Our objective functions consider both t...

摘要：Although online shopping is becoming popular, consumers who are unsure about whether to buy a product may find it advantageous to visit a brick-and-mortar retail store to first examine the product before purchasing it. But, after browsing at the store, consumers have the option of switching to an e-tailer to purchase the item at a cheaper price rather than buying at the store. Recent business press refers to this browse-and-switch behavior as showrooming, and attributes to it the declining pro...

摘要：Models of innovation diffusion typically depict an inexorable momentum once the process begins to roll. Limited production capacity, however, can place a cap on this process, leading to waiting lines of potential customers, thus diminishing overall service quality and the speed of diffusion. Identifying the minimum production capacity needed for unimpeded and unimpaired diffusion can ensure that there are no customers waiting to adopt the product. We propose a production-capacity-constrained d...

摘要：We consider a supplier selling to multiple retailers using one of two constant wholesale pricing strategies: a uniform wholesale price (UWP) vs. a retailer-specific wholesale price (RSWP). In line with the prior literature in economics, our initial finding is that as long as retailers are asymmetric, then (a) the supplier and less efficient retailer would prefer the RSWP strategy and (b) the more efficient retailer would prefer the UWP strategy. By examining the total profits of the supply cha...

摘要：This research analyzes how individual differences affect performance in judgmental time-series forecasting. Decision makers with the ability to balance intuitive judgment with cognitive deliberation, as measured by the cognitive reflection test, tend to have lower forecast errors. This relationship holds when controlling for intelligence. Furthermore, forecast errors increase for very fast or very slow decisions. We provide evidence that forecast performance can be improved by manipulating dec...

摘要：We propose a model where customers are classified into two groups: short lead-time customers who require the product immediately and long lead-time customers to whom the supplier may deliver either immediately or in the next cycle. Unmet orders are backlogged with associated costs. Specifically, the supplier faces two problems: how the on-hand inventories should be allocated between the two classes of customers and how the backlogged orders should be cleared when replenishments arrive. We trea...
