We consider the n-period economic lot sizing problem, where the cost coefficients are not restricted in sign. In their seminal paper, H. M. Wagner and T. M. Whitin proposed an O (n 2) algorithm for ...

The algorithm, revealed Monday, works by combining user-input data on sleep schedules and maximum caffeine allowance with psychomotor vigilance task (PVT) tests. As it gathers data over time and ...

In the aspect of computation, the corresponding algorithm is designed and time complexity of algorithm is calculated. Moreover, the attribute reduction model of relative knowledge granularity of ...
