We show that these problems are NP-hard even if the number of machines is two, and cannot be approximated within a factor less than 2 if the number of machines is an input unless P=NP. We present several approximation algorithms for these combination problems....

Such variability would cause problems with certain scheduling algorithms—for example, the FCFS scheduling algorithm, since jobs with large resource requirements will cause added delays to the majority of jobs that will be smaller than the mean. The effect can be further compounded by other resources...

Type A papers mainly appeared in the early stage of scheduling problem research. They usually classify the scheduling problems into several types in a certain way first, and then review various solving approaches, algorithms and conclusions for these types of problems. Theclassification resultsare simi...
The problem as stated is equivalent to that with release dates and due dates , d j , rather than delivery times, in which case the objective is to minimize the maximum lateness, L j := σ j + p j + d j , of any job j . When considering the performance of approximation algorithms...
