Exact Solutions to Task Allocation Problems

Ernst, Andreas; Jiang, Houyuan; Krishnamoorthy, Mohan - In: Management Science 52 (2006) 10, pp. 1634-1646

The task allocation problem (TAP) is one where a number of tasks or modules need to be assigned to a set of processors or machines at minimum overall cost. The overall cost includes the communication cost between tasks that are assigned to different processors and other costs such as the...

New cutting-planes for the time- and/or precedence-constrained ATSP and directed VRP

Mak, Vicky; Ernst, Andreas - In: Mathematical Methods of Operations Research 66 (2007) 1, pp. 69-98

In this paper, we introduce five classes of new valid cutting planes for the precedence-constrained (PC) and/or time-window-constrained (TW) Asymmetric Travelling Salesman Problems (ATSPs) and directed Vehicle Routing Problems (VRPs). We show that all five classes of new inequalities are...
