Generalized assignment problem

Example 13.2 Generalized Assignment Problem SAS/ORR 12.1. The assignment problem is a fundamental combinatorial optimization problem. The generalized assignment problem GAP is that of finding a maximum profit assignment from tasks to machines such that each task is assigned to precisely one machine subject to capacity restrictions on the machines.

A Survey of the Generalized Assignment Problem and Its. It consists of finding, in a weighted bipartite graph, a matching of a given size, in which the sum of weights of the edges is a minimum. AbstractGiven n items and m knapsacks, the Generalized Assignment Problem GAP is to find the optimum assignment of each item to exactly one knapsack, without exceeding the capacity of any knapsac.

Generalized Assignment Problem - GitHub A common variant consists of finding a maximum-weight matching. Generalized Assignment Problem. Algorithm implementations for the Generalized Assignment Problem. Description. The Generalized Assignment Problem GAP is the problem of assigning n jobs to m agent at minimum cost for each agent i, each job j has associated cost cij and weight wij; each agent i has a capacity ti

PDF Generalized assignment problem Generalized Assignment. This is a specialization of the maximum weight matching problem, in which the input graph is bipartite. These are usually modeled in terms of the generalized assignment problem 27, where the number of avail- able resources is essentially pre-determined and fixed, and the goal is to minimize cost.

Generalized Assignment Problem using Excel Solver Engineer. In its most general form, the problem is as follows: The problem instance has a number of agents and a number of tasks. Generalized Assignment Problem. In Generalized Assignment Problem for optimization is daily life problem in which we have n number of tasks/assignments and m number of machines/labor available to perform that tasks. Each machine/labor have some cost for performing specific task.

Generalized Assignment Problem SpringerLink Any agent can be assigned to perform any task, incurring some cost that may vary depending on the agent-task assignment. Amini MM, Racer M 1994 A rigorous computational comparison of alternative solution methods for the generalized assignment problem. Manag Sci 407868–890 zbMATH CrossRef Google Scholar

An approximation algorithm for the generalized assignment problem It is required to perform as many tasks as possible by assigning at most one agent to each task and at most one task to each agent, in such a way that the total cost of the assignment is minimized. The generalized assignment problem can be viewed as the following problem of scheduling parallel machines with costs. Each job is to be processed by exactly one machine; processing job j on machine i requires time pif and incurs a cost of c,f, each machine / is available for 7", time units, and the objective is.tminimize the total cost incurred.

Branch-and-Price for the Generalized Assignment Problem If the total cost of the assignment for all tasks is equal to the sum of the costs for each agent (or the sum of the costs for each task, which is the same thing in this case), then the problem is called linear assignment. The model implements a branch-and-price algorithm that solves a disaggregated formulation of the Generalized Assignment Problem GAP where columns represent feasible assignments of batches to machines. Column generation is applied at every node of the branch-and-bound tree.
