In the manufacture of certain products such as computers, turbines, and automobiles, various components and subassemblies must be combined in a specified assembly order over a period of time. Certain items must be on hand before others can be produced, and these requirements are determined by the product structure. Management's objective is to turn out timely products in the most economic ...

We consider a generalisation of the lot-sizing problem that includes an emission constraint. Besides the usual financial costs, there are emissions associated with production, keeping inventory and setting up the production process. Because the constraint on the emissions can be seen as a constraint on an alternative cost function, there is also a clear link with bi-objective optimisation. We s...

In this paper we investigate the complexity of the economic lot-sizing problem with remanufacturing (ELSR) options. Whereas in the classical economic lot-sizing problem demand can only be satisfied by production, in the ELSR problem demand can also be satisfied by remanufacturing returned items. Although the ELSR problem can be solved efficiently for some special cases, we show that the problem...

OBJECTIVE To evaluate the effectiveness of a rural clinical placement on students' self-perceived clinical skills and work location choice post-graduation. METHODS A one month rural placement program was introduced in 2008-2009 for 4(th) year dental undergraduates.
