Towards a Reconfigurable Supply Network Model

Through the establishment of Yuhua ring-shaped heat supply network model, the paper analyses the influence on hydraulic condition and the heat source’s flow change when heat exchange station at different locations closed. Final results show that the nearer heat users distance the closed heat exchange station, the bigger change in hydraulic condition; When the farther heat exchange station closed, it has more influence than the nearer one on the whole network’s hydraulic condition, but it has little influence on the heat source’s flow change.

Path Detection

Civil aircraft is a complex product to manufacture, and the collaborative supply network consist of grades suppliers plays an important part in the progress of development. Due to the interferences from every kind of uncertainties to the network, it’s necessary to find out the critical supply path which decides the completion date for the network going well. This paper first sets the supply network model based on the hierarchical structure of civil aircraft, and then uses Dijkstra and ant colony optimization (ACO) searching for the critical path respectively, in the last the two methods are compared in order to prove performance and superiority.

Gas Supply

The paper analyzes the impact of the sensor reading errors on parameters that affect the production costs of a leading US industrial gas supply company. For this purpose, a systematic methodology is applied first to determine the relationship between the system output and input parameters and second to identify the assigned input sensors whose readings need to be improved in a prioritized manner based on the strength of those input-output relationships. The two main criteria used to prioritize these sensors are the decrease in production costs and the decrease in production costs’ volatility obtained when the selected sensor’s precision is improved. To illustrate the effectiveness of the proposed approach, we first apply it to a simplified version of the real supply network model where the results can be readily validated with the simulated data. Next, we apply and test the proposed approach in the real supply network model with historical data.
