Internet of Things (IoT) has become a new paradigm of communication to reform traditional industries, in which distributed data automatically collected via IoT in a low cost enables many new IT services that were even impossible decades ago. This research reports on an IoT-enabled production management service for crude-oil industry. In practice, even if an optimal management decision is achieved, disruptions, such as possible oil-device failures, inclement weathers and other disturbances, arise frequently and then weaken efficiency and stability of supplement. With the help of IoT, a near-real-time management service comes into being, although the adoption of IoT brings new challenges to management of disruptions. The contributions of this article are as follows: First, a service framework is proposed for refinery which combines MQTT and Azure cloud, enabling reliable data/command delivery. Second, a …
