The second formulation considers basic process plans and bottleneck parts or bottleneck machines. The algorithms developed in the paper are illustrated with numerical examples. Computational results are also provided.DOI: 10.1287/opre.8.4.487 被引量: 209 年份: 1960 ...
To improve the solutions obtained by the constructive algorithms, fast polynomial heuristic improvement algorithms based on shift moves and pairwise interchanges of jobs are applied. In addition, metaheuristics are suggested, namely simulated annealing (SA), tabu search (TS) and genetic algorithms. ...
Summary: We study fractional scheduling problems in sensor networks, in particular, sleep scheduling (generalisation of fractional domatic partition) and activity scheduling (generalisation of fractional graph colouring). The problems are hard to solve in general even in a centralised setting; however, ...

In this report, we provide a survey of the few results known on schduling problems as well as some techniques for deriving exponential algorithms. In a second part we focus on some basic scheduling problems for which we propose exponential algorithms. 展开 ...
This paper considers the design and analysis of algorithms for vehicle routing and scheduling problems with time window constraints. Given the intrinsic difficulty of this problem class, approximation methods seem to offer the most promise for practical size problems. After describing a variety of heuri...
integer programming models for the four problems are presented and the computational complexity is analyzed.Then the operations of batching,production and delivery are integrated to provide polynomial time algorithms for the supply chain scheduling problems.For each algorithm,the time complexity and ...
This theoretical result implies that unless P=NP, we cannot solve any of these large set of scheduling problems in polynomial (efficient) time. Therefore, there is a need for designing exact algorithms to solve small instances of this set of hard problems, along with heuristic algorithms that ...
