Pathological manifestations originate mainly in the production process of the poles, and knowing which measures can be taken in the production process to avoid pathological manifestations in the poles is the main problem. The purpose of this research is to elaborate these measures that will mitigate the pathological manifestations present in the company, which are blisters, spots and segregation. For this, the entire fabrication will be evaluated, making a follow-up from the project, assembling the reinforcement, preparing the concrete, launching, densification and storage of the posts, and then the pathological manifestations in the parts that had their manufacturing process will be analyzed. accompanied, verifying the cause and effect relationship, to then elaborate necessary measures to minimize these problems of the produced poles. For this, service verification sheets, test reports and projects provided by the company will be used. That done, it was observed that the company was using burnt oil as a release agent and did not perform an adequate cleaning of the forms, resulting in dark spots on the posts and bubbles, and these still found a relationship with the wrong launch and thickening. Other than that, it was observed that segregation was directly related to the leakage of forms. With this, it is known that the mitigation of the company's pathological manifestations will be done with the use of an appropriate release agent, an adequate cleaning of the forms and its correct sealing, the densification of the concrete with sufficient number of vibrators for its uniform densification together with the training of the employees responsible for concreting the posts.

Maintenance management is an orderly procedure to address the planning, organization, monitoring and evaluation of maintenance activities and associated costs. The maintenance management allows to have an efficient tool either to the management of the preventive or curative activity, an optimization of the production tool, and finally a follow-up of the costs and the performances. A good maintenance management system can help prevent problems and damages to the operating and storage environment, extend the life of assets, and reduce operating costs.In this paper, we will first present our model on the joint management of spare parts and maintenance. We will do a simulation study of our model, presented in the first section of this paper. The results of this study are presented in the second section through the presentation of the influence of certain parameters of the model on the operation of the system under consideration. This study carried out on the graphical interface of Matlab, which is one of the performance evaluation techniques. It allows to visualize the variations and anomalies which can be reached in the system considered as an overcoming of the repair of the machines by the unforeseen breakdowns.

In view of the production quality management of filter rods in the manufacturing and execution process of cigarette enterprises, this paper analyzes the necessity of implementing the manufacturing execution system (MES) in the production process of filter rods. In this paper, the filter rod quality system of cigarette enterprise based on MES is fully studied, and the constructive information management system demand analysis, cigarette quality control process, system function module design, implementation and test effect are given. This paper utilizes the Fuzzy analytic hierarchy process to find the optimal system for processing the manufacturing of cigarette. The implementation of MSE based filter rod quality information management system for a cigarette enterprise ensures the quality control in the cigarette production process. Through visualization, real-time and dynamic way, the information management of cigarette production is completed, which greatly improves the quality of cigarette enterprise manufacturing process.

Production of components, necessary for the construction of the machine resp. or device is a demanding manufacturing process. One of the possibilities of increasing efficiency and production quality is the introduction of unconventional technologies to the production process. Knowing the dependence of the impact of non-conventional technologies on the mechanical properties of products and their subsequent verification is an important aspect when designing and manufacturing them. The article deals with the impact of used unconventional technology, that means laser, plasma and water jet on the roughness of a cutting edge and microhardness of material S 355 J2 G3.

Two patients are reported in whom there was an association between the occurrence of optic neuritis with atrophy and the administration of isoniazid for the treatment of tuberculosis. Although a cause and effect relationship was not established, discontinuation of isoniazid therapy in one patient was followed by gradual improvement of the eye lesions. The authors assume that the optic lesions were neurotoxic effects of isoniazid and recommend that pyridoxine be given daily for prophylaxis.

Abstract This study aims to determine and identify the causes of defects in the production process of PT. Triteguh Manunggal Sejati and know the level of sigma level. This research uses the six sigma method with the DMAIC approach as a quality control tool, which includes the Define, Measure, Analyze, Improve and Control stages. Based on this study the results obtained are the level of sigma level at PT.Triteguh Manunggal Sejati is 4.96, which means that in the stage of sigma level the company has not reached the level of six sigma levels because in the production process at PT.Triteguh Manunggal Sejati still has product defects in the production process not yet achieved zero defect. The causes of product defects are based on cause and effect diagrams namely lid / seal defects are leaky lid, broken lid, and tilted lid. Kata kunci : Defect, Six Sigma, DMAIC, cause and effect diagram
