Abstract: Current environmental, social and economic sustainability challenges are increasingly becoming sources of motivation for both manufacturing and service companies when attempting to innovate their businesses. In recent years, there has been growing interest from academics, policy-makers and practitioners on service innovation as a new business logicfor companies to address societal challenges regarding sustainability. Nevertheless, research specifically focusing on service innovation in relation to sustainability is scarce and ultimately scattered across different research fields. Thereby, only limited clues are available for companies willing to address sustainability challenges through service innovation. To encourage further research in this direction, this paper systematically reviewed the available literature by investigating peer-reviewed publications (from 2004 up to and including 2015) across different fields, which jointly focus on services, innovation and sustainability. The literature review confirmed both the growing amount of research on service innovation in relation to sustainability, as well as the lack of an overarching field to clearly identify such a phenomenon. The review also revealed that three main existing research streams (service innovation, product-service system and sustainability-oriented innovation) contribute to the investigation topic, though all have specific focuses when it comes to the sustainability and innovation dimensions considered. Taking stock of the descriptive and thematic analysis of the review and the identified research gaps, the paper concludes by discussing the need for a clear recognition of the emerging field of sustainability-oriented service innovation, and by outlining several future research pathways for its further enhancement.

Abstract: This paper studies a scheduling problem application for the optimization of the employees used in aircrafts’ refueling in a medium size airport. The problem is modelled as a particular resource leveling problem for which we provide a mixed integer mathematical formulation that we solve with CPLEX. The model allows to evaluate and analyse different scenarios that could be considered by the company in place of the current one in order to rearrange the available human resources used in refueling activity. Experimental results on a set of real test cases provided by an oil & gas company are discussed.

The United Nations aspirational agenda for sustainable development calls for the shared efforts of governments, business sector, society and stakeholders to promote prosperity while protecting the planet. In the business perspective, the joint pursuit of both durable competitive advantages and long-term benefits for society are not just the result of companies’ reactions to goals of institutions or demands of stakeholders. Rather, they depend on a holistic integration of sustainability in companies’ strategic decision-making.

This paper proposes an application of the fuzzy Analytic Hierarchy Process (AHP) method for selecting those sustainability issues that are most relevant for creating shared value for both business and society, and that should be the focus of strategic planning and management. The integration of the ISO 26000 framework with the method permits a holistic treatment of all areas of sustainability. The paper also illustrates to managers how the method should be applied in practice through a step-by-step application to a medium-sized company operating in the water technology sector. Finally, its usefulness as a managerial tool for strategic decision-makers is discussed.
