This paper deals with the production planning of a manufacturing system based on a dry machining process, which is considered a “green process” because it does not require the use of cutting fluids. Two types of raw materials with different prices and environmental impact are considered. The aim is to derive a cost-effective production plan over a specified time frame. Such a plan is achieved through total average cost minimization which incorporates the costs of raw materials, production, energy use, recycling, storage, shortages and CO 2 emissions. Demand is taken to be stochastic during the finite time model, consisting of discrete successive production periods. A mathematical model is established that expresses the average total cost as a function of decision variables, which are the quantities of each of the two types of products to be produced in each period. A numerical solving algorithm is devised for the problem at hand and is put to test. To demonstrate how to use the developed format and its consistency, a numerical example is proposed.
