摘要:
A method of scheduling delivery of at least one of goods (e.g., repair parts) and services (e.g., repair services) includes inputting a performance objective (e.g., a plurality of performance objectives), and network data pertaining to a network of mobile points, and generating (e.g., by utilizing the input network data and the performance objective) a delivery schedule for a delivery vehicle (e.g., one or more delivery vehicles) to deliver the at least one of the goods and services.
摘要:
A method for determining the set of winning bids in a combinatorial auction. Two variants of the method are disclosed. The first method is appropriate when the number of players and the number of combinations of items that are bid on by an individual player are relatively small. The second method is applicable when either of these values becomes large.
摘要:
A computer-based method and system comprising three data structures: partially ordered data structure (or simply ordered data structure), contiguous list v, and vector p, is used for solving a large sparse triangular system of linear equations which utilizes only the non-zero components of a matrix to solve large sparse triangular linear equations and generates explicitly only the non-zero entries of the solution. A list of the row indices of the known non-zero values of x which require further processing is stored in the ordered data structure. Actual non-zero values of x are stored in the contiguous list v and the corresponding pointers to the location of these values are stored in the vector p. The computer-based method manipulates these three matrices to find a solution to an upper or lower sparse triangular system of linear equations. In addition, in the instance a matrix becomes dense (or increases in density) by the presence of many active rows, a partitioning method is described via which the dense matrix problem is solved.
