dcterms:description
Increased utilization of production capacities has a positive impact on competitiveness of a company both in the area of cost savings and in customer service. The effort to increase the utilization of production capacities should be primarily focused on bottlenecks which limit the production capacity of the entire production system. The objective of this article is to propose and evaluate possible measures leading to increased permeability of heat treatment of forged pieces process. The proposed measures result from an analysis of a concrete forging process where heat treatment had been identified as the bottleneck. Dynamic and stochastic simulation technique is applied in order to evaluate their impacts. The article describes the construction of the simulation model of a forging process, testing and validating the model, design of the experiment, conducting the experiments, evaluating the results, and implementation. The simulation model includes all technological operations from forging of pieces on a forging press, through flame cutting of the front parts of forged pieces, their tagging, cooling on cooling beds, heat treatment in two furnaces, repeated cooling, straightening and hardening to shot blasting. Twenty five simulation experiments – combinations of possible measures have been identified, realized and evaluated. Modelling and simulation of the process uses WITNESS 2007 software tool. The realized experiments demonstrate the opportunities to increase the permeability of heat treatment and thus the entire forging process by up to 70%.
