“…This makes the borderline between planning and scheduling very tight. The problem of scheduling in a multi-site manufacturing context has been reported in several articles (Bruns and Sauer 1995;Miller and Matta 2003;Lin et al 2015;Marandi and Fatemi Ghomi 2019;etc.). The multi-site planning, scheduling and integration of planning and scheduling literature in a multi-site context has been…”

This paper proposes a multi-site global optimisation model of blending operations, alternative routings and order scheduling with a co-production flow. It is performed in a phosphoric supply chain owning three open-pit mines of different geological structures and chemical compositions, each having a dry blending plant. One main challenge of the phosphate industries is to produce merchantable ores (MO) that verify a quality charter (chemical composition) with chemical heterogeneous source ores (SO). Thus, a process of SO blending followed by a treatment is mostly necessary to obtain the required MO. Six alternative routings exist to produce an MO; one of them involving a calcination plant generates a co-product. The model objective is to determine the least costly production program of a set of MO orders to be delivered within precise time windows, in given quantities and compliance with a specific quality charter, by assigning for each MO its blending plant, routing, blend of SOs and production schedule; it also defines the feeding of the blending plants. A real case study illustrates the proposed model.

In recent decades, manufacturers’ intense competitiveness to suit consumer expectations has compelled them to abandon the conventional workflow in favour of a more flexible one. This new trend increased the importance of master production schedule and make-to-order (MTO) strategy concepts. The former improves overall planning and controls complexity. The latter enables the production businesses to reinforce their flexibility and produce customized products. In a production setting, fluctuating resource capacity restricts production line performance, and ignoring this fact renders planning inapplicable. The current research work addresses the MPS problem in the context of the MTO production environment. The objective is to resolve Rough-Cut Capacity Planning by considering resource capacity fluctuation to schedule the customer’s order with the minimum cost imposed by the company and customer side. Consequently, this study is an initial attempt to propose a mathematical programming approach, which provides the optimum result for small and medium-size problems. Regarding the combinatorial intrinsic of this kind of problem, the mathematical programming approach can no longer reach the optimum solution for a large-scale problem. To overcome this, an innovative agent-based heuristic has been proposed. Computational experiments on variously sized problems confirm the efficiency of the agent-based approach.

“…However, given many reasons, they are believed not to be suitable proxies for the contemporary macroeconomic condition of the country. For instance, the production of flat glass, an important material directly used in industries such as the construction industry, cannot be easily altered as the furnace used in the production process cannot be stopped on a regular basis (Caner Taşkın & Tamer Ünal 2009). By contrast, this is not the case for the steel scrap market.…”

Steel scrap is an important raw material in the steel making industry. As steel is a vital metal in modern life, the price of steel scrap is viewed as an important indicator of the macroeconomic activity. Steel scrap is consumed mainly in the electric arc furnace steel making, which represents approximately 30 per cent of the world annual steel production. Unlike other minerals including iron ore, both the supply and consumption amounts of steel scrap can be relatively easily adjusted based on the contemporary industrial activity level. For this reason, the steel scrap price reflects the condition of the macro economy and thereby it can be used as an indicator of future stock market performance in the country by market participants. Nevertheless, there is not much research on the market of steel scrap. This study aims to close this gap by testing the lead-lag relationship between the changes of steel scrap price and the aggregate Japanese stock market movement. Our empirical analyses suggest that the steel scrap price changes are informative in explaining the future stock market performance in Japan.
