The use of global suppliers has increased considerably over the last three decades. Operations management theory establishes that global sourcing requires more units of inventory, but since these units are often procured at a lower cost from global suppliers the capital invested in inventory and the consequent financial burden may increase or decrease with global sourcing. This study provides r...

Social media monitoring has been initially adopted by private sector firms in order to collect opinions, complaints and questions concerning their products and services, to be used for making appropriate changes and improvements of them and also for designing communication strategies. Recently government agencies have started adopting SMM, as a form of ‘passive citizen-sourcing’, in order to co...

In the networking age, Chinese government have done much on official online platforms for providing service and improving interaction between government to citizen (G2C). However the problem is the G2C platforms seem always could attract only part of citizen participation. Although most previous studies discuss e-participation, e-government service adoption from technological perspectives or pe...

The benefits of global sourcing as part of a firm’s purchasing strategy have been widely discussed in the academic literature, yet so there are few models that provide a comprehensive risk and cost assessment to guide managerial decision-making. In particular, few models capture the dynamic nature of many cost drivers, such as transportation and energy cost, labour cost inflation, or carbon off...

This paper applies the Red Queen theory to explain how organizations utilize various sourcing arrangements in order to compete in an evolutionary arms race where only the strongest competitors will survive. This case study incorporates competition and views sourcing strategies as a means to improve its viability to survive in the marketplace. The study begins with a review of sourcing literatur...

Outsourcing has advanced to an important measure that is applied broadly in operations management. Nowadays, suppliers of manufacturing companies do not only provide direct material like raw material and operational supplements but offer components and advanced modules incurring many value-adding stages. Whereas in the past companies built up local supplier networks, they recently tend to searc...

S upply disruptions are all too common in supply chains. To mitigate delivery risk, buyers may either source from multiple suppliers or offer incentives to their preferred supplier to improve its process reliability. These incentives can be either direct (investment subsidy) or indirect (inflated order quantity). In this study, we present a series of models to highlight buyers’ and suppliers’ o...

As suppliers provide more value in today’s supply chains, eliciting supplier cost-reduction efforts and inducing supplier competition are two important levers for a buyer to reduce sourcing costs. In this paper, we study a buyer’s sourcing strategy considering supplier effort and competition. The buyer has two instruments in her strategy: the composition of the supply base and the contracting m...

To cope with the uncertainty of labor supply from freelance/self-scheduling drivers, some ride-sourcing platforms recruit contractual who are paid a fixed salary for pre-specified work schedules. This paper develops an aggregate modeling framework to examine practicability such dual-sourcing strategy. We investigate optimal contract design dual sourcing under demand uncertainty, varying price s...

The potential of open data as a resource for driving citizen-led urban innovation relies not only on a suitable technical infrastructure but also on the skills and knowledge of the citizens themselves. This paper describes how a smart city project in Milton Keynes, UK, is supporting multiple stages of citizen innovation, from ideation through to citizen-led smart city projects. This approach en...
