Abstract: A heater condition monitoring and accessing method includes steps as follows: A plurality of history operating data of a heater under test are acquired, wherein each of the history operating data has a temperature, an operating sequence, and a resistance. A plurality subsets of the history operating data corresponding to a predetermined temperature range are picked up from the history operating data to form a resistance-operating sequence characteristic curve. At least one test is performed according to the resistance-operating sequence characteristic curve to determine whether a fault of the heater under test occurs at the current operating run or at the subsequent operating run and to evaluate the remaining useful life of the heater under test.

Abstract: A tree search-based scheduling method and an electronic apparatus are provided. In the method, multiple order lists are received and a schedule is initialized, wherein each order list includes multiple production operations. In each order list, a first production operation which has not been joined into the schedule yet is selected, such that multiple prior operations are selected. An execution priority of the prior operations is calculated according to multiple dispatching rules, and multiple candidate operations are selected from the prior operations according to the execution priority. Afterwards, the candidate operations are listed as a next operation of the schedule respectively, and a scheduling simulation is performed according to the dispatching rules to obtain multiple scheduling indicators of the candidate operations. Scheduling is performed according to the scheduling indicators.
