摘要：This study introduces a universal Dome appointment rule that can be parameterized through a planning constant for different clinics characterized by the environmental factorsno-shows, walk-ins, number of appointments per session, variability of service times, and cost of doctor's time to patients time. Simulation and nonlinear regression are used to derive an equation to predict the planning constant as a function of the environmental factors. We also introduce an adjustment procedure for appo...

摘要：Firms in service and make-to-order manufacturing industries often quote lead times and prices to customers. We define uniform quotation mode (UQM) as the strategy where a firm offers a single lead time and price quotation, and differentiated quotation mode (DQM) is where a firm offers a menu of lead times and prices for customers to choose from. Both modes are followed in practice. Firms should determine which is more profitable. We classify customers into two groups: lead time sensitive (LS) ...

摘要：Faced with demand uncertainty across multiple product lines, many companies have recourse to flexible capacities which can process different products in order to better balance the trade-off between capacity utilization and cost efficiency. Many studies demonstrated the potential benefit of using flexible capacity at the aggregate level by treating a whole plant or a whole process as a single stage. This paper extends these analyses by studying the benefits of flexible capacity while consideri...

摘要：Examination of team productivity finds that team familiarity, i.e., individuals' prior shared work experience, can positively impact the efficiency and quality of team output. Despite the attention given to team familiarity and its contingencies, prior work has focused on whether team members have worked together, not on which team members have worked together, and under what conditions. In this paper, I parse overall team familiarity to consider effects of geographic location and the hierarch...

摘要：We consider a dual-sourcing inventory system, where procuring from one supplier involves a high variable cost but negligible fixed cost whereas procuring from the other supplier involves a low variable cost but high fixed cost, as well as an order size constraint. We show that the problem can be reduced to an equivalent single-sourcing problem. However, the corresponding ordering cost is neither concave nor convex. Using the notion of quasi-convexity, we partially characterize the structure of...

摘要：It is becoming increasingly common to involve external technology providers in developing new technologies and new products. Two important phases involved in working with technology vendors are vendor selection and vendor management. Because for both steps theory development of key decision guidelines is still immature, we use detailed case studies of 31 innovation outsourcing projects at Siemens to develop grounded theory on provider selection criteria and on project management success driver...

摘要：This paper focuses on the issues of coalition formation and cost allocation in a joint replenishment system involving a set of independent and freely interacting retailers purchasing an item from one supplier to meet a deterministic demand. The papers dealing with this problem are mainly focused on supperadditive games, where the cost savings associated with a coalition increase with the number of players in the coalition. The most relevant question addressed then is how to allocate the saving...

摘要：We consider settings in which a revenue manager controls bookings over a sequence of flights. The revenue manager uses a buy-up model to select booking limits and updates estimates of the model parameters as data are accumulated. The buy-up model we consider is based upon a simple model of customer choice, wherein each low-fare customer who is not able to purchase a low-fare ticket will, with a fixed probability, buy up to the high fare, independent of everything else. We analyze the evolution...

摘要：We consider the transport of containers through a fleet of ships. Each ship has a capacity constraint limiting the total number of containers it can carry and each ship visits a given set of ports following a predetermined route. Each container has a release date at its origination port, and a due date at its destination port. A container has a size 1 or size 2; size 1 represents a 1 TEU (20-foot equivalent unit) and size 2 represents 2 TEUs. The delivery time of a container is defined as the ...
