We consider the extended economic production quantity (EPQ) problem when demand follows a Poisson process in a production system. A fixed lot sizing policy is implemented to minimize fluctuation of workload, and to smooth production planning and inventory control. The considered costs include...

This series of discussions presents commentaries on where the field of healthcare operations management is now and possible future research directions, expanding upon the key points raised by Green [Green LV (2012) The vital role of operations analysis in improving healthcare delivery....</i>

In our prior work on product diffusions in presence of a capacity constraint, we postulated that a firm operating in such an environment should always attempt to fulfill as much of the present demand as is possible with the capacity constraint. In other words, the firm would never have demand...

This paper introduces a newsvendor approach for capacity planning of information and communication technologies (ICT), in particular the hardware. Contrary to the reference models in computer sciences, which are primarily concerned with technical aspects and a high system utilization, this...

The purpose of this article is to determine the optimal nonlinear pricingrules for water services. The model presents a standard water distributionsystem and a separate wastewater collection and treatment system. Technicaland financial constraints are considered. The optimization process of...

In optimisation models, the characteristic features of capacity investment and dispatch planning of supply technologies are well explored for electricity systems. Little attention to date has been paid to exploring these features in an adequate manner for heat systems. This paper discusses the...

In this paper, we consider the problem of making simultaneous decisions on the location, service rate (capacity) and the price of providing service for facilities on a network. We assume that the demand for service from each node of the network follows a Poisson process. The demand is assumed to...

The current literature in the rail–truck intermodal transportation of hazardous materials (hazmat) domain ignores congestion at intermodal yards. We attempt to close that gap by proposing a bi-objective optimization framework for managing hazmat freight that not only considers congestion at...

In semiconductor manufacturing, machines are usually qualified to process a limited number of recipes related to products. It is possible to qualify recipes on machines to better balance the workload on machines in a given toolset. However, all machines of a toolset do not have equal uptimes and...

As ports have become key logistics nodes in global chains, port management of container operations has been experiencing radical changes. Moreover, the ramifications of the associated policy-making expand well beyond their own boundaries. The challenging managerial environment is further...
