Planejamento e controle da produção de cilindros para laminação: um estudo de caso quantitativo

Este trabalho apresenta um modelo de otimização-simulação aplicado em um estudo de caso real no setor de cilindros para laminação de uma siderúrgica, buscando melhorar o gerenciamento da área/equipamento gargalo da linha de produção. A simulação atuou em conjunto com um modelo de otimização da programação linear inteira (PLI) para melhorar o atendimento de prazo junto aos clientes em uma produção não seriada. Como resultado deste procedimento combinado da PLI e simulação, o processo produtivo foi otimizado e as filas de espera e o lead-time foram reduzidos, melhorando o atendimento aos clientes.

A importância da rapidez de atendimento em supermercados: um estudo de caso

Neste trabalho, analisam-se algumas causas pelas quais clientes frequentam um supermercado, tais como: preço de produtos, localização do estabelecimento, rapidez de atendimento, qualidade de atendimento, variedade de produtos, estacionamento e outras. Por meio de análise estatística multivariada, foi verificada a relevância de cada causa em contraste com as outras, ou seja, a importância relativa de cada uma. Assim, pôde-se observar que a rapidez de atendimento desempenha um papel importante em relação às demais para o nível de serviço dos clientes. Utilizando-se análise de agrupamentos hierárquicos de variáveis e análise de correspondência, associaram-se causas em grupos e relacionaram-se causas a alguns fatores, como, por exemplo, escolaridade dos clientes, sendo esta uma observação interessante por existir, no Brasil, uma relação significativa entre renda e escolaridade. A coleta de dados foi realizada em um supermercado no interior de São Paulo e, desta forma, os resultados baseiam-se em um estudo de caso, tendo limitações inferenciais.

Analytical and Monte Carlo approaches to evaluate probability distributions of interruption duration

Regulatory authorities in many countries, in order to maintain an acceptable balance between appropriate customer service qualities and costs, are introducing a performance-based regulation. These regulations impose penalties-and, in some cases, rewards-that introduce a component of financial risk to an electric power utility due to the uncertainty associated with preserving a specific level of system reliability. In Brazil, for instance, one of the reliability indices receiving special attention by the utilities is the maximum continuous interruption duration (MCID) per customer.This parameter is responsible for the majority of penalties in many electric distribution utilities. This paper describes analytical and Monte Carlo simulation approaches to evaluate probability distributions of interruption duration indices. More emphasis will be given to the development of an analytical method to assess the probability distribution associated with the parameter MCID and the correspond ng penalties. Case studies on a simple distribution network and on a real Brazilian distribution system are presented and discussed.

Chronological Monte Carlo-based assessment of distribution system reliability

Regulatory authorities in many countries, in order to maintain an acceptable balance between appropriate customer service qualities and costs, are introducing a performance-based regulation. These regulations impose penalties, and in some cases rewards, which introduce a component of financial risk to an electric power utility due to the uncertainty associated with preserving a specific level of system reliability. In Brazil, for instance, one of the reliability indices receiving special attention by the utilities is the Maximum Continuous Interruption Duration per customer (MCID). This paper describes a chronological Monte Carlo simulation approach to evaluate probability distributions of reliability indices, including the MCID, and the corresponding penalties. In order to get the desired efficiency, modern computational techniques are used for modeling (UML -Unified Modeling Language) as well as for programming (Object- Oriented Programming). Case studies on a simple distribution network and on real Brazilian distribution systems are presented and discussed. © Copyright KTH 2006.

Melhoria de processos de serviços prestados em assistência técnica

Currently the service sectors have an increasingly important role in the productive sector because they can represent a great advantage to the consumer. In this graduate work a study was conducted with the objective of process improveme nt services in the sector of technical assistance in a factory machinery and equipment. Through process mapping, through the technical blueprint, and time study were able to identify opportunities for improvement for reducing the time customer service, as well as the proposed performance indicators for the service

Improving logistics services through the technology used in fleet management

Outsourcing logistics has established itself in the area of the LSP (Logistics Service Provider), which offers a range of services to its customers. In this line, transportation is characterized as one of the most important services, and therefore efficient fleet management is essential for establishing a high level of customer service. With advances in technology and vehicle tracking systems, this approach of management has gained new possibilities for the improvement of logistics services. By studying the specific case of an LSP, this paper investigates the use of these technologies in the management of their business and services. The results indicate that the LSP seeks to increase its services and to streamline information in order to respond to customer needs in real time. It is also evident in this case under study that the combination of the technology available together with the fleet management system has become a distinguishing feature for this LSP, one which increases their skills and important information for both customers and business.

Aplicação do desdobramento da função qualidade (QFD) para melhoria da qualidade em um restaurante self-service

Currently, with the competitiveness that is seen in the market, it is crucial to the success of the business, develop new strategies to keep and win new customer preference. To ensure the success of a particular service or product, the secret is to continually meet the wishes and demands of the customers, which are the key parts of the business, through innovation, variety and quality assurance. To achieve this goal managers should be aware of all types of process that exist in the company, as they are primarily responsible and interested by quality service, customer satisfaction and consequently, generating favorable financial results. A tool used to ensure good results to business is the Quality Function Deployment (QFD) that seeks to hear and interpret customers requirements and turn them into essential features for a project
