Towards robust service workflows: a decentralized approach

Nowadays service workflows are used to increase the efficiency of process oriented supply chains. Service workflows can encompass hundreds of services around a single process. These services are geographically spread and cross organizational boundaries. This raises the need for coordination, such as assigning tasks, synchronizing production schedules, between companies collaborating through services. We present a fully decentralized coordination mechanism that, using the local knowledge available at each company participating in the supply chain, allows the enactment of robust processes. We evaluate our solution through simulations and show that it can create robust service compositions.
