An Enhanced Memetic Algorithm for Single-Objective Bilevel Optimization Problems

Abstract: Bilevel optimization, as the name reflects, deals with optimization at two interconnected hierarchical levels. The aim is to identify the optimum of an upper-level leader problem, subject to the optimality of a lower-level follower problem. Several problems from the domain of engineering, logistics, economics, and transportation have an inherent nested structure which requires them to be modeled as bilevel optimization problems. Increasing size and complexity of such problems has prompted active theoretical and practical interest in the design of efficient algorithms for bilevel optimization. Given the nested nature of bilevel problems, the computational effort (number of function evaluations) required to solve them is often quite high. In this article, we explore the use of a Memetic Algorithm (MA) to solve bilevel optimization problems. While MAs have been quite successful in solving single-level optimization problems, there have been relatively few studies exploring their potential for solving bilevel ...

Doing social good on a sustainable basis: competitive advantage of social businesses

Abstract: Purpose – The purpose of this paper is to investigate the capabilities of social entrepreneurship (SE) firms and how they achieve competitive advantage while engaging in social value creation. The authors employ a business model perspective to understand the (self-) sustaining mechanism for social good. Design/methodology/approach – The authors carry out an in-depth investigation of three SE ventures. The authors analyse the history of these ventures to determine how they achieved competitive advantage. The cases are analysed based on the internal development in the context of environmental support. Findings – The authors find that SE ventures, like all other organisations, achieve competitive advantage based on available resources such as reputation and network of the founder, managerial experience and other corporate resources within the firm. The authors also find that the competitive advantage often comes from innovate usage – a practice that is reinforced by the support from institutional environment...

Prior Related Work Experience and Job Performance: Role of personality

Abstract: In contrast to the general notion, recent studies presented a negative or insignificant relationship between prior related work experience (PRWE) and job performance (JP) and suggestively attributed the theoretically inconsistent results to individual factors. Using a sample of 688 sales persons in the insurance industry, the present study found support for the positive relationship between PRWE and JP. Further, the study found the moderation effect of personality factors on the above relationship. Implication of the study to the practitioners and the academia is discussed.
