The decision of when to calve beef females is critical to production efficiency and profitability in a cow and calf enterprise. Calf production and associated costs are affected by calving season because environmental conditions, stage of production, and season of the year interact to affect nutritional status and reproductive performance. Cow and calf producers typically choose to commence cal...

determining production rate considering costs and revenues in order to maximize profit is one of the applied problems in small and medium size factories. mostly existing models in production planning consider production system statically and specify production rate, although the factors determining production rate include many different changes in practice. in fact, by increasing the production...

Just-In-Time (JIT) is a lean manufacturing tool, which provides the benefits of efficiency, and of minimizing unnecessary costs for many organisations. However, the risks arising from these benefits have been disregarded. These risks impact on system processes disrupting the whole supply chain. This paper proposes an inventory model that can simultaneously reduce costs and risks in JIT systems....

This paper is interested in a food industrial group which produces large quantities of sugar and distributes it to warehouses and customers. The group should review its distribution policy, in particular, to optimize transportation costs and reduce losses caused by the current organization. In this paper, we propose an integer linear model to optimize the travel of full loaded trucks taking int...

The process industries exhibit an increasing need for efficient management of all the factors that can reduce their operating costs, leading to the necessity for a global multi-objective optimization methodology that will enable the generation of optimum strategies, fulfilling the required restrictions. In this paper a genetic algorithm is developed and applied for the optimal assignment of all...
