Publication number: 20240296395Abstract: A near-optimal scheduling system for considering processing-time variations and real-time data streaming includes a data parser module, a publish subscribe mechanism module, a processing time prediction module and a scheduling optimization module. In the processing time prediction module, an orthogonal greedy algorithm and a recurrent neural network are used to extract key features and then predict varying operation processing time. By formulating the scheduling problem in an integer programming form, an ordinal-optimization (OO) embedded decomposition and coordination method is established in the scheduling optimization module to provide dynamic and near-optimal schedules in a computationally efficient manner. Moreover, a publish subscribe mechanism is developed in the publish subscribe mechanism module by using subscribe and publish methods to realize real-time needs.Type: ApplicationFiled: June 1, 2023Publication date: September 5, 2024Inventors: Tsung-Han TSAI, Bing YAN, Peter B.

Patent number: 8839913Abstract: A near-optimal scheduling method for a group of elevators uses advance traffic information. More particularly, advance traffic information is used to define a snapshot problem (24) in which the objective is to improve performance for customers. To solve the snapshot problem (24), the objective function is transformed into a form to facilitate the decomposition of the problem into individual car subproblems (26). The subproblems (26) are independently solved using a two-level formulation, with passenger to car assignment (28) at the higher level, and the dispatching of individual cars (30) at the lower level. Near-optimal passenger selection and individual car routing (38) are obtained. The individual cars are then coordinated through an iterative process (40, 42) to arrive at a group control solution that achieves a near-optimal result for passengers.Type: GrantFiled: June 19, 2012Date of Patent: September 23, 2014Assignees: Otis Elevator Company, University of ConnecticutInventors: Mauro J.

Patent number: 5715165Abstract: A method and system for scheduling using a facet ascending algorithm or a reduced complexity bundle method for solving an integer programming problem is presented. A Lagrangian dual function of an integer scheduling problem is maximized (for a primal minimization problem) to obtain a good near-feasible solution, and to provide a lower bound to the optimal value of the original problem. The dual function is a polyhedral concave function made up of many facets. The facet ascending algorithm of the present invention exploits the polyhedral concave nature of the dual function by ascending facets along intersections of facets. At each iteration, the algorithm finds the facets that intersect at the current dual point, calculates a direction of ascent along these facets, and then performs a specialized line search which optimizes a scaler polyhedral concave function in a finite number of steps.Type: GrantFiled: December 23, 1994Date of Patent: February 3, 1998Assignee: The University of ConnecticutInventors: Peter B.
