This paper considers production planning of multi-site production facilities with substitutable capacities serving multiple selling locations where the supplying plant is dynamically determined. A linear programming model is developed to produce the time and capacity aggregated plan and the detailed plan simultaneously to overcome the …

Today, as mentioned before, aggregate production and recycling are defined in the form of crushing and in the central and the mobile plant types. In this research, with regard to the large-scale proposed recycling plan for Iran, only is the central type (fixed) considered. NA production (the first scenario) consists of three stages.

The production of aggregate for the infrastructural development of the country has been increasing for the last three decades due to the high urbanization rates in the main cities of the country and the ever-growing demand for basic infrastructural facilities. The environmental impact of both fine and coarse aggregate production is …

We define productivity growth as the change in welfare that arises from additional output holding primary inputs constant. Using this traditional growth-accounting definition, we show that gains may arise because of plant-level technology shocks, and, in imperfectly competitive settings, from the reallocation of inputs across plants with …

Production costs in general, and workforce and inventory costs in particular, constitute a large fraction of the operating costs of many manufacturing plants. We introduce cooperative aggregate production planning as a way to decrease these costs. That is, when production planning of two or more facilities (plants) is integrated, …

Research findings indicate that regardless of the manufacturing plant used, the price of recycled concrete aggregate cannot decrease below the price of natural aggregate concrete. The key result of this research is that recycled concrete aggregate manufacturing set-ups can be used in the industrial-scale manufacture of recycled …

Slag, that is obtained from iron and steel plants during the steel production, is brought to the discharge plant (slag tippling plant and site) via railways. Molten steel slags are subject to various methods of cooling; simple cooling, cooling with blasting water, cooling with water, cooling with air, and the shallow pool method.
