Information technology (IT) services are indispensable in enterprise sustainability programs. For the outsourcing of IT services, many companies use the contract service model and set up a project to implement timely IT requests which constantly arrive at different IT sites. The demand for outsourced IT services and related workforce coordination is a permanent decisional process, yet existing studies mainly focus on the one-time assignment or the centralized service model. Hence, this paper bases on the multi-period and multi-service allocation requirement to develop a sustainable assignment model. The model handles continuous service requests and decentralized worker assignments to optimize overall costs under the fixed-price contract type of IT service. A real industrial service case is reported to illustrate the model. A comparative review with related works is also provided to discuss the contributions of the model and to outline its future research and development.
