Abstract
Decision of planning input for make-to-order system based on learning rate is researched in the paper, affect of employee learning rate on the qualified rate in the manual operating system is analyzed and characteristics of the qualified rate’ s random fluctuation under the changing production condition are studied. We propose that the random fluctuation of qualified rate is determined by different requirements in specifications, technical difficulties, materials of make-to-order and the random uncertainty characteristics of the production system itself. Considering of affects of learning rate and random factors on the qualified rate, a model of decision-making of planning input is established with the objective to minimize the total expected expenses composed of the costs about excess output, output gaps and scrap losses. By simulating with MathCAD, it is proved that there is an optimal input as customers’ orders are certain.
