Redução de desperdícios no serviço de atendimento ao consumidor: estudo de caso do orçamento base zero em uma empresa de linha branca

The self-evaluation is increasingly necessary in a competitive environment, and a way for companies to self-evaluate is through your budget. Knowing the importance of this budgetary process, this study aimed to observe and analyze the developing process of a zero-based budgeting (ZBB) highlighting its best practices and difficulties and propose recommendations for other companies in general. This goal was achieved through a case study in an area responsible for the budgeting process in the customer services department from a white-goods company. Also was required to review the literature regarding the customer services area, waste reduction, cost management, budgets in general and the zero-based budgeting. After reviewing the literature and the study, we can highlight good practices and difficulties observed in the studied company, and also propose recommendations on how to develop a zero-based budget and evidence what plans, analyzes and justifications are essential in a good budget process execution

Análise do sistema de medição em uma linha produtiva de radar

In this work, we analyze a measurement system that will be implanted in a wheels production line, in order to use those wheels for buses and trucks. The measurement device has to be approved according to the MSA study, due to the fact that the mentioned industry is an automobilistic supplier, so that it has to be conform with the ISO/TS 16949 standards. We showed the MSA studies, as well as some concepts for the work understanding. The airlock wheels systematic production is also broached, that is to say, wheels that use airlock tyres, with a better attention given to the rim production, where the device must be implanted. We analyze and assess the data’s acceptance according to the guidelines showed in this study, along with this, improvement proposals are elaborated and their analysis is made, in order to check the obtained results. Finally, we survey the analyzed measurement system, and new studies are suggested, with the intention of improving it

Análise e redução de custos e peso em veículo rodoviário de carga reboque linha de eixos

Load transportation in brazilian territory is made difficult by a deficient highway network, result of low maintenance and lack of government supervision. The problem aggravates when we consider the transportation of indivisible loads, mainly because the brazilian highways are not prepared for such task and few companies in Brazil have the necessary equipment suited for this kind of transport. In this dissertation it will be shown the analysis of a specific equipment to transport overweight indivisible loads, called hydraulic modular multi axle trailer. From an existing project (RB.04LE-01), manufactured and homologated in Brazil, it has been studied how the components in this trailer work so it could have been possible to elaborate a new model (RB.04LE-02), with two main objectives: reduction of costs and weight with subsequent increase in the liquid load for roadway transportation. The trailer’s components analyses were made utilizing the theory of fatigue strength of materials and finite element method with the von Misses criteria for a more safety when realizing the calculations

Análise da influência do torque de montagem na resistência de parafusos de fixação

Whereas the assembly torque calculation has great importance on efficiency and life of bolts, the objective of this study was to analyze the combined stresses during assembly, the friction coefficient, compare the rupture torque results with the indicated torques by standards and to present a new torque method without the stress combination (shear stress and normal stresses). For this study were carried eighteen tests with different diameters and materials, this bolts were undergoing five ranges torque until the breaking torque. With the experimental rupture torque values for each test and with the bolt quality certificate was possible to calculate the friction coefficient so compared with the theory. Another comparison was the experimental rupture torque with assembly torque indicated by NBR-8800 and ASME-PCC. The main conclusion are related to combined stress, because for this factor can fail at the assembly time, so for in some cases must use the tensioning method, because in this method won't be present torsional stresses
