Gig Work Systems Design for Dynamic Work Management with Freelancers

Gig work is a work style in which freelancers undertake one-off jobs based on their own convenience. One can see that the gig work system is a management system that matches one-off jobs with registrant freelancers under their free decision-making. This paper addresses a systematic design of the gig work system. To this end, first, we model the decision-making by the freelancers and the evolutions in remaining workloads. We express the probability that at least one of the registrant freelancers gets opportunities of one-off jobs based on their utility. Next, we design a model-based controller, which matches one-off jobs with them. Finally, the effectiveness of the proposed work management system is verified in numerical experiments.
