“…The production lines involve several process stages, where the rhythm or capacity is determined by bottleneck operation. In order to avoid a structural under-use of the available capacity, Vanhoucke and Debels (2009) introduced an unused capacity of the previous period to the capacity of current period. We refer to this capacity flexibility as capacity shift.…”

“…Each production line has a limited capacity expressed in hours, which may not be exceeded by all assigned steel plate orders as eq.(10). In order to avoid a structural under-use of the available capacity, unused capacity of the previous period 1 md ta   is added (Vanhoucke and Debels 2009). The capacity to be allocated should be limited by upper and lower bound as eq.(11).…”

“…A study employing the Lagrangian relaxation approach to address the steelmaking process scheduling is also presented in Tang et al (2002). As heuristic optimisation methods, there are Roy et al (2004), Vanhoucke andDebels (2009) andDong et al (2010). Note that many of the aforementioned research studies combined their main optimisation methods and other strategies to some or much degree.…”

Scheduling of die casting operations including high-mix low-volume and line-type production

This article addresses the scheduling problem of a real die casting shop. The problem is of practical importance and yet complicated, especially for a modern casting environment where a variety of cast products made of different alloys are simultaneously manufactured in relatively small lot sizes. As a simple and robust scheduling methodology, a Linear Programming (LP) model is proposed so as to determine the quantity of each product in a casting shift. The solution of the LP model maximises the average efficiency of melting furnaces, i.e., the percentage use of molten alloys throughout the shifts. Our model can represent a most general casting environment to the extent that some die casting machines carry out frequent in-process die exchanges for flexible manufacturing. At the same time, we employ line-type casting as well as a combination die with multi-cavities which can cast dissimilar shapes concurrently. In the high-mix low-volume manufacturing world, the proposed LP model can assist the die casting industry to strengthen its competence by providing an optimal schedule that satisfies practical constraints on casting processes.

“…to deal with real-life problems. A finite-capacity procedure for a Belgian steel company has been developed by Vanhoucke and Debels (2009) in which a multi-objective function consisting of five different cost functions is minimized under consideration of very company specific constraints. It is desirable to prevent capacity problems at the MRP calculation stage using an integrated approach of MRP and capacity planning.…”
