We examine the problem of estimating clearing functions that relate the expected output of a production resource as a function of its expected workload, from empirical data. We use a simulation model of a scaled-down wafer fabrication facility to generate the data and evaluate the performance of the resulting clearing functions. We compare several different regression approaches and report computational...
Refined Oil demand has great influence on the planning, operation and control of Refined Oil systems. A combined forecasting model based on the principle of gray theories was put forward to optimize Refined Oil demand forecasting models. The example shows that combined gray forecasting model can overcome the disadvantages of individual model, raise the precision.
Web services bonding with stateful resources are different from traditional web services. Because the state of those resources can be highly dynamic which make it difficult to discover and combine proper web services and fulfill clients' demand. This paper proposes a new method of web services description and registration based on WSRF (Web Service Resource Framework), aiming to provide real-time...
The production process inside a hospital surgery department is made up of three distinct main sub-processes: waiting list management, operating theatre planning and scheduling, stay area sizing and organization. Overall department performance depends on how these sub-processes are managed as well as they are integrated. In the literature, they are mainly treated separately recurring to two approaches:...
A primary component of the wafer assembly and final testing phases of the semiconductor manufacturing process is the process of binning wherein integrated circuits are tested for speed, voltage, and other functionality requirements. Customer demand for products is satisfied using binned components. While higher functionality components can be used to satisfy lower-level demand at a profit loss, the...
To solve the problem of process instances adaptation caused by dynamic process changes in workflow systems, a solution of workflow instance migration based on automatic planning mechanism was proposed, in which AI planning methods were used in migrating workflow system. The initial state and the target state of migrating instance were expressed with disjunction of an order prediction, the HTN method...
The distribution system problems, such as planning, loss minimization, and energy restoration, usually involve the phase balancing or network reconfiguration procedures. The determination of an optimal phase balance is, in general a combinatorial optimization problem. Several Algorithms have been proposed and had achieved good result. However, the running time may be very high or the algorithm can...
This paper researches the data association problem in mobile robot simultaneous localization and mapping (SLAM) and try to solve this problem with the thought of simulate anneal arithmetic. The essentiality of data association in SLAM is analyzed and then the data association problem is transformed into a combinatorial optimization problem, defined by variables and functions in details. The simulate...
