摘要：Despite high demand and resource limitations, humanitarian organizations (HOs) typically do not share resources and/or coordinate in the field. While coordination enhances operational performance and saves costs, the general perception is that it dilutes the media attention that individual organizations might receive, and negatively influences their future donation income. In this study, we empirically unveil the impact of media exposure and operational performance on the donations obtained by...

摘要：We consider a product sold in multiple variants, each with uncertain demand, produced in a multi-stage process from a standard (i.e., generic) sub-assembly. The fan-out point is defined as the last process stage at which outputs are generic (outputs at every subsequent stage are variant-specific). Insights gained from an analytical study of the system are used to develop heuristics that determine the stage(s) at which safety inventory should be held. We offer a relatively-simple heuristic that...

摘要：Past research (along with our experience) suggests that a firm's supply chain (i.e., value chain) plays an integral role in its ability to not only reduce cost via process innovation, but also in its ability to develop new products and services. Evidence suggests the value chain is playing an ever-more-important role, with greater prevalence of distributed product development (spanning geographic, organizational, or firm boundaries) and open innovation (performed outside the firm). We discuss ...

摘要：Motivated by our experience with a global company, we propose and study the concept of a semi-centralized supply chain and analyze its coordination issues. We focus on a supply chain consisting of a home plant and a foreign branch, both of which are under the same parent company but have considerable autonomy. The role of the home plant is to provide a key component to the foreign branch with guaranteed service (required by the headquarters). Because of a high fixed order cost, the branch orde...

摘要：We consider the inventory management problem of a firm reacting to potential change points in demand, which we define as known epochs at which the demand distribution may (or may not) abruptly change. Motivating examples include global news events (e. g., the 9/11 terrorist attacks), local events (e. g., the opening of a nearby attraction), or internal events (e. g., a product redesign). In the periods following such a potential change point in demand, a manager is torn between using a possibl...

摘要：This note analyzes the effects associated with reducing demand uncertainty in a decentralized supply chain comprising one manufacturer, one retailer, and a wholesale price contract that governs the transactions between them. The demand uncertainty level is parameterized through a mean-preserving spread, and the manufacturer's and the retailer's equilibrium decisions are solved accordingly. We consider the case of an exogenous retail price as well as the case of an endogenous retail price, and ...

摘要：We consider production and service systems that consist of parallel lines of two types: (i) M/M/1 lines and (ii) lines that have no buffers (loss systems). Each line is assumed to be controlled by a dedicated supervisor. The management measures the effectiveness of the supervisors by the long run expected cost of their line. Unbalanced lines cause congestion and bottlenecks, large variation in output, unnecessary wastes and, ultimately, high operating costs. Thus, the supervisors are expected ...

摘要：We examine the value of price commitment in a non-profit organization using individual-level purchases over a series of concert performances. To decide on a pricing policy, the performing arts organization must be able to accurately measure when each ticket will be sold and what type of audience will purchase the tickets for each performance. We use a competing hazards framework to model the timing of ticket purchases when customer segments differ in their valuations and arrival times. We show...

摘要：The practice of diverting genuine products to unauthorized gray markets continues to challenge companies in various industries and creates intense competition for authorized channels. Recent industry surveys report that the abuse of channel incentives is a primary reason for the growth of gray market activities. Therefore, it is crucial that companies take the presence of gray markets into consideration when they design contracts to distribute products through authorized retailers. This issue ...

摘要：We consider a multi-stage inventory system with stochastic demand and processing capacity constraints at each stage, for both finite-horizon and infinite-horizon, discounted-cost settings. For a class of such systems characterized by having the smallest capacity at the most downstream stage and system utilization above a certain threshold, we identify the structure of the optimal policy, which represents a novel variation of the order-up-to policy. We find the explicit functional form of the o...
