A systems engineering approach to performance-based maintenance services design

Traditionally, industrial services have been mainly transaction-based, i.e., the equipment user pays the service provider for getting a job done or providing assistance and support for equipment operations. Recently, a trend has emerged of increasing the relational perspective of these services, which are becoming more oriented towards customer value and service performance levels. Among these emergent industrial services, performance-based services represent an opportunity for equipment manufacturers to transform their service offerings towards more relational and customer-oriented services. The purpose of this work is to study the design of a generic performance-based maintenance service under a novel perspective given by systems engineering. This paper is intended to serve as a starting point to fully understand this type of services and to develop a method that can support equipment manufacturers who wish to advance their service offerings

Combination of end-of-life strategies for extension of industrial equipment life cycle

As many manufacturing companies are changing their production philosophies from a traditional focus on the manufacturing of the physical product towards a focus on the life cycle of the physical product, it is becoming important to engineer product's life cycle. Even more, many industrial researchers of the last decade see product's life cycle prolonging activities as a business opportunity both in economical and environmental ways. As a result, more focus is now put on the use phase and end-of-life phase, including maintenance and remanufacturing. The analysis of current end-of-life practices identifies significant improvements to product design that reduce the impact of manufactured goods on the environment as whole. Life cycle engineering and product take-back is a routine for many large industries and corporations nowadays, but, it is still a big challenge for a small and medium companies. In context of end-of-life strategies implementation, there is a very little experience for smaller firms, and results are often controversial. This paper will touch material processing equipment end-of-life strategies combination perspectives, real-life implementation of them, benefits and consequences. The case study is made on a basis of a lorry that will be transferred into spoil mixing plant

Green Manufacturing in Machinery Industry

Green manufacturing cuts across every aspect of manufacturing including product development, process technologies, energy consumption and material flow. Becoming green can be viewed as a process where we start using more eco-friendly manufacturing resources that have low embedded energy and come from renewable resources. Green Manufacturing covers the whole life cycle of product, from requirements specification, design, manufacturing, and maintenance to final discarding. Green design is the most significant part of product's life cycle. Term "green" means that design should consider the product's impact on the environment and causes minimal pollution. This term includes such important approaches as design for the environment (DFE), design for disassembly (DFD), and design for recycling (DFR). Manufacturers can think about the end-of-life approaches across a wide range of products they use in production processes, for example, different machines, machine-tools, material handling equipment, cranes, etc. The analysis of current end-of-life practices identifies significant improvements to product design that reduce the impact of manufactured goods on the environment as whole. The scope of this paper is to describe possible product's end-of-life strategies on the basis of material handling equipment case study

Lean and TRIZ: from the problems to creative and sustainable solutions

Lean Thinking philosophy pursuit continuous improvement and continuous innovation towards economic and eco-sustainable growth by new solutions. Such solutions involve eco-efficient products (goods and/or services) and cleaner production to produce them. Nevertheless, sometimes, there are technical contradictions that inhibited companies to achieve good solutions. TRIZ is a methodology capable to solve such contradictions and Lean could use it. Lean and TRIZ are on the road to achieve sustainable development goals, directly, the Goal 12, responsible consumption and production. This paper presents some case studies where this alliance is recognized and credited. These case studies were collected and synthetized by: type of work developed, company/sector, main TRIZ and Lean principles and tools used, problem(s) to solve and products/solutions designed. Building on the results, the authors systematized that Lean and TRIZ impact the design of creative solutions. Many of such solutions were developed in students’ master dissertations that reveals the importance of teaching Lean allied with TRIZ.FCT - Fundação para a Ciência e a Tecnologia (UID/CEC/00319/2019
