We critically discuss the Jefferson/D'Hondt and Webster/Sainte-Laguë methods, which are used to allocate parliament seats to parties in the mixed-member proportional representation systems in Germany, New Zealand, Bolivia, South Africa, South Korea, Scotland and Wales, as well as in the...

This study was conducted to investigate the problem of robust integrated project scheduling and material ordering in terms of resource constraints, uncertainty, and lag times. Simultaneous consideration of discount, non-renewability, perishability, uncertainty, and different project...

The offshore oil and gas exploration and production activities must be supported by a fleet of supply vessels. The offshore installations are supplied by these vessels on a periodic basis from an onshore supply depot. Petrobras must decide on the number of supply vessels hired to perform the...

In this paper, we investigate an enhanced indexation methodology using robust Conditional Value-at-Risk (CVaR) and group-sparse optimization. A featured difference from the existing literatures is to describe the tail risk using the worst-case CVaR of excess returns (WCVaR-ER), and the process...

We characterize x-directional monotone comparative statics in function spaces, generalizing the results in Barthel and Sabarwal (2018) for finite-dimensional Euclidean spaces, and showing that their proofs generalize to infinite-dimensional spaces. Our generalizations include those for...

Edge computing brings computing and storage resources close to end-users to support new applications and services that require low network latency. Examples of such applications include augmented reality, connected cars, gaming and video analytics. The latency of accessing such applications must...

The globalization of world economy intensified the growth of containerized transportation since decades which shows several benefits of reducing the cost and damage of potential goods, consequently, plays an eminent role in intermodal trading which can prolong economic development. Due to its...

In this paper, an extended finite element method and a curve-fitting procedure are incorporated into an implicit level set method to construct a three successive shape transformation steps topology optimization approach inspired for manufacturing fields. The extended finite element method plays...

Renal patients which have a willing but incompatible donor can decide to participate in a kidney exchange program (KEP). The goal of a KEP is to identify sets of such incompatible pairs that can exchange donors, leading to compatible transplants for each recipient. There is significant...
