On Dynkin's model of economic equilibrium under uncertainty.

Carlier, Guillaume; Evstigneev, Igor - Université Paris-Dauphine - 2001

The article analyzes the Dynkin (1975) stochastic model of economic equilibrium. We solve a question regarding this …

A Stochastic Version of a Stackelberg-Nash-Cournot Equilibrium Model

Wolf, Daniel De; Smeers, Yves - In: Management Science 43 (1997) 2, pp. 190-197

We consider a stochastic version of the Stackelberg-Nash-Cournot model proposed by Murphy et al. (Murphy, F. H., H. D. Sherali, A. L. Soyester. 1983. Stackelberg-Nash-Cournot equilibria characterizations and computations. Oper. Res. 31 253--276.). In the first stage, the leader chooses and...

Reservation Planning for Elective Surgery Under Uncertain Demand for Emergency Surgery

Gerchak, Yigal; Gupta, Diwakar; Henig, Mordechai - In: Management Science 42 (1996) 3, pp. 321-334

This work concerns the advance scheduling of elective surgery when the operating rooms' capacity utilization by emergency surgery, as well as by elective procedures, is uncertain. New requests for bookings of elective surgery arrive each day. Such procedures preferably would be performed as soon...

La dinámica de la deuda pública: una perspectiva estocástica aplicada al caso español

Alloza, Mario; Martínez Pagés, Jorge; Rojas, Juan; …

This paper presents a methodology for analysing public debt sustainability that incorporates factors that enable uncertainty in the macro-financial environment to be quantified. The aim is to identify risks, not only under specific assumptions, but also considering a complete characterisation of...

On Properties of Stochastic Inventory Systems

Zheng, Yu-Sheng - In: Management Science 38 (1992) 1, pp. 87-103

For most order quantity/reorder point inventory systems, the stochastic model, which specifies the demands as … stochastic model has been limited because of the absence of insightful analytical results on the model. This paper analyzes the …) in contrast to the deterministic EOQ model, the controllable costs of the stochastic model due to selection of the order …

Optimal Centralized Ordering Policies in Multi-Echelon Inventory Systems with Correlated Demands

Erkip, Nesim; Hausman, Warren H.; Nahmias, Steven - In: Management Science 36 (1990) 3, pp. 381-392

This paper treats a depot-warehouse system in which demand occurs at the warehouse or retail level. This work differs from a number of other studies in that we allow item demands to be correlated both across warehouses and also correlated in time. Our motivation for this generalization arises...

Planning for Surprise: Water Resources Development Under Demand and Supply Uncertainty I. The General Model

Erlenkotter, Donald; Sethi, Suresh; Okada, Norio - In: Management Science 35 (1989) 2, pp. 149-163

A study of water resources development in South Sweden revealed that water consumption unexpectedly stopped growing after construction had begun on a large project to expand water supplies. The project had a long lead time for completion, and planning had been based on traditional deterministic...

A Model for Assessing the Value of Warehouse Risk-Pooling: Risk-Pooling Over Outside-Supplier Leadtimes

Schwarz, Leroy B. - In: Management Science 35 (1989) 7, pp. 828-842

This paper constructs and analyzes a multi-location inventory model to examine the value of warehouse risk-pooling in high service-level systems. Specifically, risk-pooling over the outside-supplier leadtime is examined. Two alternative systems of N identical retailers are formulated. In System...

Economic Design of Control Charts with Different Control Limits for Different Assignable Causes

Tagaras, George; Lee, Hau L. - In: Management Science 34 (1988) 11, pp. 1347-1366

The use of multiple control limits and multiple corresponding levels of response for processes is an effective way for statistical process control when different assignable causes exist which lead to different out-of-control states of the processes, and different restoration procedures. This...
