摘要：The existing queueing literature typically assumes that customers either perfectly know the expected waiting time or are able to form rational expectations about it. In contrast, in this article, we study canonical service models where customers do not have such full information or capability. We assume that customers lack full capability or ample opportunities to perfectly infer the service rate or estimate the expected waiting time, and thus can only rely on past experiences and anecdotal re...

摘要：The agricultural sector plays an important role in emerging economies even though most farmers are trapped in the poverty cycle owing to their smallholdings. Aggregating farmers through formal or informal cooperatives (coops) can enable them to: (i) reduce production cost; (ii) increase/stabilize process yield; (iii) increase brand awareness; (iv) eliminate unnecessary intermediaries; and (v) eliminate price uncertainty. To examine whether these effects will benefit the members of such aggrega...

摘要：Online material and waste exchanges (OMWEs) provide online channels to repurpose by-products, unused materials and waste from industrial and commercial facilities. Unfortunately, OMWE's also have challenges. First, sellers may have access to other disposal options and, as a result, may not fully commit to the exchange. Second, buyers can face high uncertainty about the product exchanged and the transaction being undertaken. Overcoming these challenges is the last hurdle to making OMWEs success...

摘要：Most service systems consist of multidepartmental structures with multiskill agents that can deal with several types of service requests. The design of flexibility in terms of agents' skill sets and assignments of requests is a critical issue for such systems. The objective of this study was to identify preferred flexibility structures when demand is random and capacity is finite. We compare structures recommended by the flexibility literature to structures we observe in practice within call c...

摘要：Firms often cite cost savings as a reason why they charge separately for add-ons. Firms also often face situations where consumers' price sensitivity is correlated with their valuation of add-ons. While cost savings may directly translate into profit gains in some scenarios, this study examines the strategic implications of add-on pricing and is the first to suggest that cost savings from add-on pricing may in fact result in profit loss for firms when consumers are heterogeneous in price sensi...

摘要：We consider a stochastically failing component that will be needed at a random future time when an emergency occurs. If the component is not operational at that time, the system incurs a large penalty, which we want to avoid through inspections and replacements. We propose a model and solution algorithm for finding an inspection policy that minimizes the infinite horizon discounted expected penalty, replacement, and inspection costs. We also discuss structural properties of the solution, as we...

摘要：This note complements the study of Burke, Carillo, and Vakharia ( hereafter BCV) which analyzes a class of single-product multisourcing problems under stochastic demand and random yields. The purpose is twofold. First, we prove that the objective function used by these authors is only a lower bound for the expected profit for which we provide the correct expression. Second, we show on some of the numerical instances provided in BCV's study that the structure and the performance of the BCV orde...

摘要：This study examines a deterministic material requirements planning (MRP) problem where lead times at subsequent ordering moments differ. Adequate replenishment methods that can cope with lead time differences are lacking because of the order crossover phenomenon, that is, replenishment orders are not received in the sequence they are ordered. This study specifies how to handle order crossovers and recalculate planned order releases after an update of gross requirements. The optimal (s, S) poli...
