Abstract
In this paper, the single-machine scheduling problem is studied by simultaneously considering due-date assignment and group technology (GT). The objective is to determine the optimal sequence of groups and jobs within groups and optimal due-date assignment to minimize the weighted sum of the absolute value in lateness and due-date assignment cost, where the weights are position dependent. For the common (CON) due-date assignment, slack (SLK) due-date assignment, and different (DIF) due-date assignment, an O n log n time algorithm is proposed, respectively, to solve the problem, where n is the number of jobs.
Highlights
It is well known that firms can increase production efficiency by adopting the group technology (GT). e group technology is an approach to manufacturing that seeks to improve efficiency in highvolume production by exploiting the similarities of different products and activities in their production (Neufeld et al [1] and Yang et al [2]). rough decades of application, people have found many advantages of the group technology
Li et al [17] considered three due-date assignment methods under group technology. e objective function is to minimize the weighted sum of earliness, tardiness, due-date assignment, and completion time
For each of the three due-date assignment methods, there exists an optimal schedule with zero machine idle times
Summary
It is well known that firms can increase production efficiency by adopting the group technology (GT). e group technology is an approach to manufacturing that seeks to improve efficiency in highvolume production by exploiting the similarities of different products and activities in their production (Neufeld et al [1] and Yang et al [2]). rough decades of application, people have found many advantages of the group technology. Brucker [21] considered the CON due-date scheduling problem of minimizing the total cost comprising the total weighted absolute lateness value and common due-date (CON) cost, where the weight is position dependent He proved that the problem can be solved in a time O(n log n). Under the linear and convex resource consumption functions, they proved that the CON and SLK due-date assignment problems can be solved in polynomial time, respectively. We proceed to the study Brucker [21], Liu et al [18], and Wang et al [19], which is an extension of their work from considering the CON, SLK, and DIF due-date assignment scheduling problems with group technology and position-dependent weights.
