This paper describes how the proper priority structure of non-linear goal programming (NLGP) model can be selected for obtaining economic order quantity(EOQ) of multi-item inventory problems. In the solution process, sensitivity analysis of the priority under the given weight structure of goals has been performed. A set of solution is obtained. From the solutions, the ideal solution is identifi...

The design of closed-loop logistics (forward and reverse logistics) has attracted growing attention with the stringent pressures of customer expectations, environmental concerns and economic factors. This paper considers a multi-product, multi-period and multi-objective closed-loop logistics network model with regard to facility expansion as a facility location–allocation problem, which more cl...

A parametric optimization problem of cross-sectional sizes for cold-formed steel lipped channel structural members subjected to axial compression has been considered by the paper. An is formulated as define optimum member taking into account post-buckling behavior (web and flange local distortional buckling) well requirements when profile perimeter (strip width), thickness, design lengths mater...

trauma is the most common cause of mortality and morbidity in pediatric population. caring for the injured child requires special knowledge, precise management, and scrupulous attention to details. all clinicians who are responsible for the care of a pediatric trauma patient, including pediatricians, pediatric emergency room clinicians, and trauma surgeons, must be familiar with every tenet of ...

This manuscript investigates the supercritical carbon dioxide (sCO2) power cycle employed in block of concentrated solar (CSP) plants—solar tower—as an alternative for desalination, developed with either distillation or reverse osmosis. concept is investigated as a possible up-scaling SOLMIDEFF project, originally based on hot-air micro gas turbine combined dish collector. For upscaled concept,...

This paper deals with preference representation and aggregation in combinatorial domains. We assume that the set of alternatives is defined as the cartesian product of finite domains and that agents’ preferences are represented by generalized additive decomposable (GAI) utility functions. GAI functions allow an efficient representation of interactions between attributes while preserving some de...
