This note considers a problem of simultaneous selection of a subset of N projects and determination of an optimal sequence to implement these projects so as to maximize the net present value of the total return. We first establish an optimal sequence of all projects which does not depend on the...

This paper gives optimality conditions to obtain a priori precedence relationships among some of the jobs in a single machine scheduling problem so as to curtail the enumeration while using branch-and-bound technique. The objective is to minimize a quadratic (or generalized quadratic) penalty...

We present a unified analysis for single-machine scheduling problems in which the actual job processing times are controlled by either a linear or a convex resource allocation function and also vary concurrently depending on either the job's position in the sequence and/or on the total...

The research work on supply-chain management has primarily focused on the study of materials flow and very little work has been done on the study of upstream flow of money. In this paper we study the flow of money in a supply chain from the viewpoint of a supply chain partner who receives money...

The aim of this article is to explain the transition from implicit CSR to explicit CSR that has taken place in Scandinavia over the last two decades. Matten and Moon’s (Academy of Management Review, 33:404–424, <CitationRef CitationID="CR39">2008</CitationRef>) distinction between implicit and explicit CSR is the point of departure for...</citationref>

The United Nations Global Compact (UNGC) was created in 2000 to leverage UN prestige and induce corporations to embrace 10 principles incorporating values of environmental sustainability, protection of human rights, fair treatment of workers, and elimination of bribery and corruption. We review...
