摘要:In procurement auctions, the object for sale is a contract, bidders are suppliers, and the bid taker is a buyer. The suppliers bidding for the contract are usually the current supplier (the incumbent) and a group of potential new suppliers (the entrants). As the buyer has an ongoing relationship with the incumbent, he needs to adjust the bids of the entrants to include non-price attributes, such as the switching costs. The buyer can run a scoring auction, in which suppliers compete on the adju...

摘要:Seasonal demand for products is common at many companies including Kraft Foods, Case New Holland, and Elmer's Products. This study documents how these, and many other companies, experience bloated inventories as they transition from a low season to a high season and a severe drop in service levels as they transition from a high season to a low season. Kraft has termed this latter phenomenon the landslide effect. In this study, we present real examples of the landslide effect and attribute its ...

摘要:We consider a patient admission problem to a hospital with multiple resource constraints (e. g., OR and beds) and a stochastic evolution of patient care requirements across multiple resources. There is a small but significant proportion of emergency patients who arrive randomly and have to be accepted at the hospital. However, the hospital needs to decide whether to accept, postpone, or even reject the admission from a random stream of non-emergency elective patients. We formulate the control ...

摘要:To alleviate poverty in developing countries, governments and non-governmental organizations disseminate two types of information: (i) agricultural advice to enable farmers to improve their operations (cost reduction, quality improvement, and process yield increase); and (ii) market information about future price/demand to enable farmers to make better production planning decisions. This information is usually disseminated free of charge. While farmers can use the market information to improve...

摘要:This study analyzes optimal replenishment policies that minimize expected discounted cost of multi-product stochastic inventory systems. The distinguishing feature of the multi-product inventory system that we analyze is the existence of correlated demand and joint-replenishment costs across multiple products. Our objective is to understand the structure of the optimal policy and use this structure to construct a heuristic method that can solve problems set in real-world sizes/dimensions. Usin...

摘要:Few unfocused factories outperform competitors, but focus is elusive because the environment is constantly evolving and this requires changes to a factory's key tasks. So how can focus be achieved and sustained? We present insights derived from an historical analysis of the German Hewlett-Packard server plant which went through a series of focus changes over the years. Using this example, we provide clues for the right timing of focus changes and discuss critical structural and infrastructural...

摘要:Gray markets, also known as parallel imports, have created fierce competition for manufacturers in many industries. We analyze the impact of parallel importation on a price-setting manufacturer that serves two markets with uncertain demand, and characterize her policy against parallel importation. We show that ignoring demand uncertainty can take a significant toll on the manufacturer's profit, highlighting the value of making price and quantity decisions jointly. We find that adjusting prices...

摘要:This study empirically investigates consumer perceptions of remanufactured consumer products in closed-loop supply chains. A multi-study approach led to increasing levels of measure refinement and facilitated examination of various assumptions researchers have made about the consumer market for remanufactured products. Based in part on the measure building studies, an experimental study examined remanufactured product perceptions from a national panel of consumers. The consumers responded to r...
