A new model for the asymmetric vehicle routing problem with simultaneous pickup and deliveries

  • Authors: Agarwal Y.K., Venkateshan P.
    Year: 2020 | IIM Ahmedabad
    Source: Operations Research Letters
    DOI: 10.1016/j.orl.2019.11.005

The asymmetric vehicle routing problem with simultaneous pickup and deliveries is considered. This paper develops four new classes of valid inequalities for the problem. We generalize the idea of a no-good cut. Together, these help us solve 45-node randomly generated problem instances more efficient...(Read Full Abstract)

Logit choice models for interactive attributes

In multi attribute decision making (MADM), the choice of a decision-maker (DM) is often the result of an interplay between the DM's unique attitude, the utilities (specific to the DM) for the attributes, and the degree of positive (or negative) interaction among the attributes. Based on this conglom...(Read Full Abstract)

Parametric binary regression models are used in group testing to estimate the covariate adjusted prevalence. Unlike the standard binary regression model (viz., logistic, complementary log–l...(Read Full Abstract)

What drives human resource acquisition and retention in social enterprises? An empirical investigation in the healthcare industry in an emerging market

Although healthcare is one of the fastest growing sectors in the world, it faces crucial shortages in human resource (HR) availability and retention. This challenge is worsened in social enterprises. In this research, we build on a multimethod and a multistudy approach. In the first study, using an ...(Read Full Abstract)

In such a set-up, basically two types...(Read Full Abstract)

A Robust Sharpe Ratio

Sharpe ratio is one of the widely used measures in the financial literature to compare two or more investment strategies. Since it is a ratio of the excess expected return of a portfolio to its standard deviation of returns, it is not robust against the presence of outliers. In this paper we propose...(Read Full Abstract)
